Description

This disclosure generally relates to an environmental control system, a livestock shed, a sensible temperature calculation method, and a program, and more specifically to an environmental control system equipped with a sensible temperature calculation system used in a space where livestock are present, a livestock shed, a sensible temperature calculation method, and a program.

Patent document 1 describes an environmental control system that controls the environment inside and outside an open-type chicken coop (see, for example, patent document 1).

The poultry house in which the environmental control system described in Patent Document 1 is used is equipped with temperature and humidity sensors, wind speed sensors, and gas sensors for ammonia, etc. The environmental control system inputs each detection value into a control computer via control means, compares it with a control program input in advance, and outputs the collated and analyzed results from the control terminal of the poultry house via the control means, thereby comprehensively controlling each control device.

Patent document 1 describes factors that play a major role in egg productivity, such as perceived temperature, perceived humidity, perceived illuminance, perceived gas concentration, and perceived wind speed. Furthermore, patent document 1 describes that in order to meet all of the above factors, detection can be performed by various sensors, and control can be performed by a control computer having a control program.

However, the conventional environmental control system described in Patent Document 1 has the problem that the accuracy of the spatial environment is low because it only indicates the temperature felt by the poultry present in the space.

The present disclosure has been made in consideration of the above points, and the purpose of the present disclosure is to provide an environmental control system, livestock barn, sensible temperature calculation method, and program that can control the environment of a space so that the actual sensible temperature of livestock throughout the space is a temperature suitable for the livestock.

An environmental control system according to one aspect of the present disclosure includes a sensible temperature calculation system, a control system, an abnormality detection unit, and a notification control unit. The sensible temperature calculation system includes a first calculation unit and a second calculation unit. The first calculation unit calculates an environmental distribution of the space using environmental information representing the environment of the space in which the livestock are present in a livestock barn where the livestock are raised.

In the control step, in an internal space of a building ventilated by a ventilation system, a wind speed of air supplied from an air intake port of the building and exhausted to the outside of the building from an exhaust port of the building through the internal space is controlled. In the abnormality detection step, livestock present in the space with an abnormal environment is detected. In the notification control step, when livestock present in the space with an abnormal environment is detected in the abnormality detection step, the notification device is controlled so as to notify at least one of the livestock present in the space with an abnormal environment and the position of the livestock present in the space with an abnormal environment via the notification device. In the control step, the height of the lower end of at least one baffle member is higher than the height of the air inlet and lower than the height of the upper end of the exhaust port. The baffle member is provided between the air inlet and the exhaust port in the internal space, and is suspended from the ceiling of the building so that there is a space between the lower end and the floor surface of the building.

(Embodiment 1)
Hereinafter, the sensible temperature calculation system, the environmental control system, the sensible temperature calculation method, and the program according to the embodiment 1 will be described with reference to the drawings. Figures 2 and 3 referred to in the following embodiment are schematic diagrams, and the ratios of sizes and thicknesses of the components in the figures do not necessarily reflect the actual dimensional ratios.

(1) Sensible Temperature Calculation System The configuration of a sensible temperature calculation system 1 according to the first embodiment will be described with reference to the drawings.

As shown in FIG. 1, the sensible temperature calculation system 1 according to the first embodiment includes an acquisition unit 11, a processing unit 12, an equipment control unit 13, a storage unit 14, and a notification control unit 15.

The sensible temperature calculation system 1 is used to determine the sensible temperature distribution of livestock 9 (see FIG. 3) in a space 7 (see FIG. 2) of a building 6 (see FIG. 2) in which the livestock 9 reside. A large number of livestock 9 reside in the space 7 (see FIG. 3).

(2) Building The building 6 in which the sensible temperature calculation system 1 is used will be described with reference to the drawings. Note that the building 6 shown in Fig. 2 is an example, and the building 6 in which the sensible temperature calculation system 1 is used is not limited to the example in Fig. 2.

As shown in FIG. 2, the building 6 includes a building body 61 having, for example, a rectangular parallelepiped shape. The building 6 also has a space 7.

In the example of FIG. 2, the building 6 is a livestock barn where livestock 9 are raised. When the building 6 is a livestock barn, the building body 61 is the livestock barn body. In the building 6, a large number of livestock 9 are raised in a space 7 (see FIG. 3). The livestock barn is, for example, a chicken barn where chickens are raised. However, the livestock barn is not limited to being a chicken barn, and may be a pig barn where pigs are raised as the livestock 9, or a cow barn where cows are raised as the livestock 9.

The building body 61 has two first side walls 62, 63 and two second side walls 64, 65.

The two first side walls 62, 63 are, for example, rectangular and are arranged along the longitudinal direction D1 of the building 6. The two first side walls 62, 63 face each other in the lateral direction D2 of the building 6 with a space 7 between them.

The two second side walls 64, 65 are, for example, rectangular and are provided along the short direction D2 of the building 6. The two second side walls 64, 65 face each other in the long direction D1 of the building 6 with a space 7 between them.

Space 7 is a space surrounded by the building body 61. More specifically, space 7 is a space surrounded by two first side walls 62, 63 and two second side walls 64, 65 in a plan view in the height direction D3.

The building 6 also has multiple (two in the illustrated example) air intakes 66 and an exhaust vent 67. Air is supplied from outside the building 6 to the space 7 through each of the multiple air intakes 66. Air is exhausted from the space 7 to outside the building 6 through the exhaust vent 67.

The multiple air intakes 66 (air intakes 661, 662) are provided at the lower ends of the first side walls 62, 63 along the longitudinal direction D1 of the building 6. More specifically, one air intake 661 is provided at the lower end of the first side wall 62 at the first end side (second side wall 64 side) of the longitudinal direction D1. The other air intake 662 is provided at the lower end of the first side wall 63 at the first end side (second side wall 64 side) of the longitudinal direction D1. One air intake 661 and the other air intake 662 face each other in the transverse direction D2 of the building 6.

The exhaust vent 67 is provided on the second end side (the second side wall 65 side) of the building 6 in the longitudinal direction D1. The exhaust vent 67 is provided near the center of the second side wall 65 in the height direction D3. The exhaust vent 67 may also be provided near the upper end of the second side wall 65.

The number of air intake ports 66 is not limited to two, and may be only one, or may be three or more. In other words, the number of air intake ports 66 must be one or more. The number of exhaust ports 67 is not limited to one, and may be two or more. In other words, the number of exhaust ports 67 must be one or more.

1 , the environmental control system 2 according to the first embodiment includes a sensible temperature calculation system 1, a plurality of measuring devices 3 (two in the illustrated example), a control device 4, and an environmental facility 5. The environmental control system 2 according to the first embodiment further includes a detection device 33 and an alarm device 21.

(3.1) Measuring Device As shown in Fig. 2, the multiple measuring devices 3 measure environmental information representing the environment of the space 7. The multiple measuring devices 3 measure physical quantities related to the environment at representative points 71 and 72 of the space 7 as the environmental information. The multiple measuring devices 3 output the measured environmental information to the sensible temperature calculation system 1.

The multiple measuring devices 3 include a measuring device 31 that measures a physical quantity related to the environment of a representative point 71 of the space 7, and a measuring device 32 that measures a physical quantity related to the environment of a representative point 72 of the space 7. The representative point 71 of the space 7 is an upwind position in the space 7. The representative point 71 is closer to the air intake 66 than the air exhaust 67 in the longitudinal direction D1 of the building 6. In the longitudinal direction D1, the distance between the representative point 71 and the air intake 66 is shorter than the distance between the representative point 71 and the air exhaust 67. The representative point 72 of the space 7 is a downwind position in the space 7. The representative point 72 is closer to the air exhaust 67 than the air intake 66 in the longitudinal direction D1 of the building 6. In the longitudinal direction D1, the distance between the representative point 72 and the air exhaust 67 is shorter than the distance between the representative point 72 and the air intake 66.

Examples of physical quantities related to the environment of space 7 include temperature, humidity, wind speed, carbon dioxide concentration, ammonia concentration, and dust concentration. For example, when measuring temperature, each measuring device 3 includes a temperature sensor. When measuring humidity, each measuring device 3 includes a humidity sensor. When measuring wind speed, each measuring device 3 includes a wind speed sensor. Note that each measuring device 3 is not limited to measuring all of temperature, humidity, wind speed, carbon dioxide concentration, ammonia concentration, and dust concentration as physical quantities related to the environment of space 7. Each measuring device 3 only needs to measure at least one of temperature, humidity, wind speed, carbon dioxide concentration, ammonia concentration, and dust concentration as physical quantities related to the environment of space 7. In other words, each measuring device 3 only needs to include at least one sensor.

Dust concentration refers to the amount of dust contained in a space per unit volume. A large amount of dust tends to be generated in space 7 where livestock 9 are present. Dust can affect the formation of body tissues of livestock 9. For this reason, it is preferable to measure the dust concentration in space 7.

(3.2) Control Device As shown in Fig. 1 and Fig. 2, the control device 4 outputs a control signal to the environmental equipment 5 to control the environmental equipment 5. More specifically, the control device 4 acquires control contents (control parameters) of the environmental equipment 5 from the sensible temperature calculation system 1. The control device 4 controls the environmental equipment 5 by outputting a control signal including the control contents acquired from the sensible temperature calculation system 1 to the environmental equipment 5.

(3.3) Environmental Equipment The environmental equipment 5 shown in Fig. 1 is equipment for controlling the environment of the space 7 (see Fig. 2). As shown in Fig. 1, the environmental equipment 5 includes a plurality of (two in the illustrated example) openable/closable windows 51 and a plurality of (three in the illustrated example) ventilator fans 52. The environmental equipment 5 controls the environment of the space 7 according to the control of the control device 4.

(3.3.1) Openable Windows The multiple openable windows 51 are provided at the air supply opening 66 of the building 6, as shown in Fig. 2. More specifically, of the multiple openable windows 51 (openable windows 511, 512), one openable window 511 is provided at the air supply opening 661 of the first side wall 62, and the other openable window 512 is provided at the air supply opening 662 of the first side wall 63.

The multiple opening and closing windows 51 are also known as tunnel doors, and open and close by rotating up and down. When the opening and closing windows 51 are open, air can be let in from outside the building 6 into the space 7 through the air intake vent 66.

(3.3.2) Ventilation Fan As shown in Fig. 2, the multiple ventilation fans 52 are provided at the exhaust port 67. More specifically, the multiple ventilation fans 52 are provided on the opposite side to the opening/closing window 51 in the longitudinal direction D1. That is, the multiple ventilation fans 52 are provided at the second side wall 65.

The multiple ventilation fans 52 are arranged in a row in the short-side direction D2. More specifically, in the short-side direction D2, ventilation fans 521, 522, and 523 are arranged in this order from the first side wall 63 side.

The multiple ventilation fans 52 exhaust air from space 7 in building 6 to the outside of building 6. More specifically, the multiple ventilation fans 52 are installed so that the air from space 7 is exhausted in substantially the same direction. This allows air from space 7 to be drawn in at a position on the exhaust side (downwind) of space 7 and exhausted to the outside of building 6.

(3.4) Detection device The detection device 33 shown in Fig. 1 detects the presence of livestock 9 (see Fig. 3). The detection device 33 includes, for example, an imaging device that images the space 7 and has a function of extracting the livestock 9 from the captured image. Alternatively, the detection device 33 includes, for example, an infrared sensor and has a function of receiving infrared rays emitted from the livestock 9. By having the above functions, the detection device 33 can detect areas in the space 7 where the livestock 9 are present and areas where there are many livestock 9. The detection device 33 outputs such detection results to the sensible temperature calculation system 1 as living body detection information.

1 notifies the livestock 9 (see FIG. 3) present in the space of the abnormal environment and the position of the livestock 9 present in the space of the abnormal environment. The notification device 21 notifies the information to be notified according to the control of the sensible temperature calculation system 1.

The notification device 21 has, for example, a display with a display function for displaying predetermined information. When the notification device 21 has a display, the notification device 21 can visually notify the livestock 9 present in the space of the abnormal environment and the position of the livestock 9 present in the space of the abnormal environment.

The notification device 21 has, for example, a speaker with an audio output function that outputs predetermined information by voice. When the notification device 21 has a speaker, the notification device 21 can audibly notify the livestock 9 present in the space of the abnormal environment and the position of the livestock 9 present in the space of the abnormal environment.

(4) Components of the Sensible Temperature Calculation System Hereinafter, each component of the sensible temperature calculation system 1 according to the first embodiment will be described with reference to the drawings.

(4.1) Acquisition Unit As shown in Fig. 1, the acquisition unit 11 acquires the measurement results of the measurement device 3 from the measurement device 3 as environmental information of the space 7 (see Fig. 2) in which livestock 9 (see Fig. 3) exist. More specifically, the acquisition unit 11 acquires environmental information representing the environments at two representative points 71, 72 (see Fig. 2) of the space 7 by wired communication or wireless communication. Here, the environmental information includes at least one of temperature, humidity, wind speed, carbon dioxide concentration, ammonia concentration, and dust concentration.

1, the processing unit 12 has a first calculation unit 121 and a second calculation unit 122. The processing unit 12 is configured as one function of a processor of a computer.

(4.2.1) First Calculation Unit The first calculation unit 121 shown in Fig. 1 calculates an environmental distribution in the space 7 by using environmental information of the space 7 (see Fig. 2). In the first embodiment, the environmental information includes information representing the environment at a plurality of representative points 71, 72 (see Fig. 2) in the space 7. Specifically, there are two representative points 71, 72. The two representative points 71, 72 are a windward position in the space 7 and a downwind position in the space 7. More specifically, as shown in Fig. 2, the representative point 71 is a windward position in the space 7, and the representative point 72 is a downwind position in the space 7.

The first calculation unit 121 shown in FIG. 1 calculates the environmental distribution of the space 7 from the environmental information of the representative points 71, 72, taking into account the layout of the space 7 of the building 6 and the positions of the representative points 71, 72 in the space 7. For example, a function is prepared in advance that takes into account the layout of the space 7 and the positions of the representative points 71, 72 in the space 7. The first calculation unit 121 calculates the environmental distribution of the space 7 by inputting the environmental information of the representative points 71, 72 into the above function. The above function is stored in the memory unit 14 in advance. Note that the method of calculating the environmental distribution by the first calculation unit 121 is not limited to the method using the above function, and other methods may be used.

(4.2.2) Second Calculation Unit The second calculation unit 122 shown in FIG. 1 calculates the sensible temperature distribution of the livestock 9 by using the environmental distribution calculated by the first calculation unit 121 and a calculation model.

Here, the sensible temperature distribution of the livestock 9 refers to the distribution of temperatures that the livestock 9 will experience in the space 7. It is difficult to measure the actual sensible temperature of the livestock 9, and when there are many livestock 9 in the space 7, it is even more difficult to measure the actual sensible temperature of each livestock 9. On the other hand, in order to measure the environmental temperature in the area where the livestock 9 are present, it is necessary to install temperature sensors in many places in the space 7.

In addition, as the livestock 9 grows, the height of the livestock 9 changes, so the sensible temperature distribution in a two-dimensional area when viewed from above the building 6 is not sufficient. Therefore, the second calculation unit 122 calculates the sensible temperature distribution of the livestock 9 as a three-dimensional distribution including not only the planar direction but also the height direction D3. This makes it possible to take into account the size of the livestock 9 at each growth stage, thereby improving the accuracy of the sensible temperature distribution of the livestock 9.

(4.2.3) Application of Processing Unit In the processing unit 12 shown in FIG. 1, the second calculation unit 122 performs calculations using a classifier that has undergone machine learning. Note that it is not limited that only the second calculation unit 122 performs calculations using a classifier that has undergone machine learning. Only the first calculation unit 121 may perform calculations using a classifier that has undergone machine learning, or both the first calculation unit 121 and the second calculation unit 122 may perform calculations using a classifier that has undergone machine learning. In short, it is preferable that at least one of the first calculation unit 121 and the second calculation unit 122 performs calculations using a classifier that has undergone machine learning.

In the first embodiment, the first calculation unit 121 and the second calculation unit 122 shown in FIG. 1 perform calculations taking into account the airflow in the space 7 (see FIG. 2). The airflow in the space 7 is based on the layout of the building 6 (see FIG. 2), the opening degree of the opening and closing window 51 (see FIG. 2), the ventilation capacity of the ventilation fan 52 (see FIG. 2), the wind speed upwind, and the wind speed downwind. Information on the airflow in the space 7 is stored in advance in the storage unit 14. Note that it is not limited that both the first calculation unit 121 and the second calculation unit 122 perform calculations taking into account the airflow in the space 7. Only the first calculation unit 121 may perform calculations taking into account the airflow in the space 7, or only the second calculation unit 122 may perform calculations taking into account the airflow in the space 7. In short, it is preferable that at least one of the first calculation unit 121 and the second calculation unit 122 performs calculations taking into account the airflow in the space 7.

The second calculation unit 122 of the processing unit 12 shown in FIG. 1 is not limited to calculating the sensible temperature distribution of the livestock 9 in the entire space 7, and may calculate it in only a part of the space 7. For example, the second calculation unit 122 calculates the sensible temperature distribution of the livestock 9 only in the area of the space 7 where the livestock 9 are present. The second calculation unit 122 calculates the sensible temperature distribution of the livestock 9 using the livestock detection information and the environmental distribution of the space 7. The livestock detection information is information that indicates the presence of the livestock 9 in the space 7. The second calculation unit 122 acquires the livestock detection information from the detection device 33.

For example, in the example of FIG. 3, the second calculation unit 122 calculates the sensible temperature distribution of the livestock 9 only for areas A1 and A4 in the space 7 where there are many livestock 9. On the other hand, the sensible temperature distribution for areas A2 and A3 is not calculated.

Furthermore, the processing unit 12 shown in FIG. 1 may have a function of tracking the position of the livestock 9. As shown in FIG. 1, the processing unit 12 has a tracking calculation unit 123. The tracking calculation unit 123 tracks the position of the livestock 9 using position information indicating the position of the livestock 9. The tracking calculation unit 123 acquires the position information from the detection device 33.

As shown in FIG. 1, the processing unit 12 further includes an abnormality detection unit 124. The abnormality detection unit 124 detects livestock 9 that are present in an abnormal environment space in the space 7. More specifically, the abnormality detection unit 124 detects livestock 9 that are present in an abnormal environment space using the detection result of the detection device 33.

(4.3) Equipment control unit The equipment control unit 13 shown in Fig. 1 controls the environmental equipment 5 (the multiple opening and closing windows 51 and the multiple ventilation fans 52). More specifically, the equipment control unit 13 controls the environmental equipment 5 based on the sensible temperature calculated by the second calculation unit 122 of the processing unit 12 so that the actual sensible temperature of the livestock 9 becomes a temperature suitable for the livestock 9. In the first embodiment, the equipment control unit 13 outputs the control contents (control parameters) of the environmental equipment 5 to the control device 4. The environmental equipment 5 controls the environment of the space 7 based on the sensible temperature distribution calculated by the second calculation unit 122 so that the actual sensible temperature of the livestock 9 becomes a temperature suitable for the livestock 9.

When the second calculation unit 122 calculates the sensible temperature distribution using the living body detection information, the equipment control unit 13 controls the environmental equipment 5 to control the environment of the area where the livestock 9 actually exist using the living body detection information. This makes it possible to control the environment of the area in the space 7 where the livestock 9 actually exist with priority over areas where the livestock 9 do not exist. As a result, the environment can be controlled efficiently.

The equipment control unit 13 also controls the environmental equipment 5 so as to control the environment of the location of the livestock 9 tracked by the tracking calculation unit 123. This allows the environment of the area in which the livestock 9 actually exists to be controlled with high precision.

(4.4) Notification control unit When the abnormality detection unit 124 detects livestock 9 present in an abnormal environment space, the notification control unit 15 shown in Fig. 1 controls the notification device 21 so as to notify the livestock 9 present in the abnormal environment space and the position of the livestock 9 present in the abnormal environment space via the notification device 21. This allows for early response to the livestock 9 present in the abnormal environment space.

1 stores a computation model used by the processing unit 12. More specifically, the storage unit 14 stores a plurality of parameters used in the computation model.

The memory unit 14 also stores the environmental distribution of the space 7 calculated by the first calculation unit 121. The memory unit 14 stores historical data of the environmental distribution of the space 7 (the calculation result of the first calculation unit 121). The historical data of the environmental distribution of the space 7 is, for example, a combination of the environmental distribution of the space 7 and the time points at which physical quantities related to the environmental information used in the calculation of the environmental distribution were measured.

Furthermore, the memory unit 14 stores the sensible temperature distribution of the livestock 9 calculated by the second calculation unit 122. The memory unit 14 stores historical data of the sensible temperature distribution of the livestock 9 (the calculation result of the second calculation unit 122). The historical data of the sensible temperature distribution of the livestock 9 includes, for example, a combination of the environmental distribution of the space 7 and the sensible temperature distribution of the livestock 9 at the time when the above-mentioned environmental distribution is obtained.

(4.6) Calculation Model The calculation model used in the processing unit 12 shown in Fig. 1 is a trained model trained using a plurality of data. The calculation model is a model for causing one or more processors to function so that, for example, an environmental distribution in a space 7 (see Fig. 2) is input to an input layer 81 (see Fig. 4) of a neural network 8 (see Fig. 4) and a sensible temperature distribution of livestock 9 is output from an output layer 82 (see Fig. 4) of the neural network 8.

The computational model is trained using multiple pieces of historical data. Each piece of historical data includes a combination of the environmental distribution in the space 7 and the sensible temperature distribution of the livestock 9 at the time the environmental information is obtained.

In the case of the neural network 8 shown in FIG. 4, the computational model is trained using multiple historical data as supervised data. When an environmental distribution is input to the input layer 81 of the neural network 8, each parameter is adjusted so that a sensible temperature distribution is output from the output layer 82 of the neural network 8.

By using such a computational model (trained model), the actual temperature felt by the livestock 9 throughout the space 7 can be brought closer to a temperature suitable for the livestock 9.

(5) Operation of Environmental Control System Hereinafter, the operation (sensible temperature calculation method) of the environmental control system 2 according to the first embodiment will be described with reference to FIG.

In the first step, multiple measurement devices 3 measure environmental information of the space 7 (S1 in FIG. 4). More specifically, the measurement device 31 measures a predetermined physical quantity related to the environment at multiple representative points 71 of the space 7, and the measurement device 32 measures a predetermined physical quantity related to the environment at multiple representative points 72 of the space 7.

In the second step, in the sensible temperature calculation system 1, the processing unit 12 calculates the environmental distribution in the space 7 using the sensor values (environmental information of the representative points 71, 72) of the sensors of the measuring devices 31, 32 (S2 in FIG. 4). The processing unit 12 calculates, as the environmental distribution in the space 7, for example, the temperature distribution in the space 7, the humidity distribution in the space 7, and the wind speed distribution in the space 7. The second step corresponds to the first calculation step.

In the third step, the environmental distribution calculated in the second step and the calculation model are used to calculate the sensible temperature distribution of the livestock 9 in the space 7. The third step corresponds to the second calculation step.

Specifically, in the third step, the processing unit 12 inputs the environmental distribution in the space 7 to the input layer 81 of the neural network 8, and outputs the sensible temperature distribution of the livestock 9 in the space 7 from the output layer 82 of the neural network 8 (S3 in Figure 4).

In the fourth step, the equipment control unit 13 outputs the control content based on the sensible temperature distribution calculated by the processing unit 12 to the control device 4, thereby controlling the environmental equipment 5 (multiple opening and closing windows 51 and multiple ventilation fans 52) (S4 in Figure 4).

In the fifth step, the environmental equipment 5 operates according to the control by the control device 4 (S5 in Figure 4).

A program for causing one or more processors to execute the sensible temperature calculation method having the second step, the third step, and the fourth step is stored in the memory unit 14 of the sensible temperature calculation system 1.

(6) Effects The sensible temperature calculation system 1 according to the first embodiment calculates the sensible temperature distribution of the livestock 9 in the space 7 by using the environmental distribution of the space 7. By controlling the environment of the space 7 in consideration of the sensible temperature distribution calculated by the first calculation unit 121, it is possible to make the actual sensible temperatures of the livestock 9 throughout the space 7 closer to a temperature suitable for the livestock 9.

In the sensible temperature calculation system 1 according to the first embodiment, the environmental information includes at least one of temperature, humidity, and wind speed. As a result, when calculating the sensible temperature distribution of the livestock 9, the accuracy of the sensible temperature distribution of the livestock 9 can be improved by using physical quantities that are likely to affect the sensible temperature of the livestock 9.

In the sensible temperature calculation system 1 according to the first embodiment, the environmental information represents the environment at at least one representative point 71, 72 in the space 7. This allows the number of measurement points of the environmental information to be reduced, and therefore the number of measurement devices 3 that measure the environmental information to be reduced.

In the sensible temperature calculation system 1 according to the first embodiment, the multiple representative points 71, 72 include an upwind position in the space 7 and a downwind position in the space 7. This improves the accuracy of the environmental distribution in the space 7, and therefore allows the sensible temperature distribution of the livestock 9 to be calculated with high accuracy.

The sensible temperature calculation system 1 according to the first embodiment calculates the sensible temperature distribution of the livestock 9 using living body detection information indicating the presence of the livestock 9 and the environmental distribution of the space 7. As a result, when calculating the sensible temperature distribution of the livestock 9, it is possible to give priority to areas in the space 7 where the livestock 9 actually exist over areas where the livestock 9 do not exist.

The sensible temperature calculation system 1 according to the first embodiment uses the living body detection information to control the environmental equipment 5 so as to control the environment of the area where the livestock 9 actually exist. This allows the environment to be controlled by prioritizing the area in the space 7 where the livestock 9 actually exist over areas where the livestock 9 do not exist. As a result, the environment can be controlled efficiently.

The sensible temperature calculation system 1 according to the first embodiment detects and tracks the position of the livestock 9 in the space 7. This makes it possible to precisely control the environment of the area in which the livestock 9 actually exist.

In the sensible temperature calculation system 1 according to the first embodiment, the second calculation unit 122 calculates the sensible temperature distribution of the livestock 9 as a three-dimensional distribution. This allows the size of the livestock 9 at each growth stage to be taken into account, thereby improving the accuracy of the sensible temperature distribution of the livestock 9.

The sensible temperature calculation system 1 according to the first embodiment detects livestock 9 present in an abnormal environment space and controls the alarm device 21 to notify at least one of the livestock 9 present in the abnormal environment space and the location of the livestock 9 present in the abnormal environment space. This allows for early response to the livestock 9 present in the abnormal environment space.

In the sensible temperature calculation system 1 according to the first embodiment, at least one of the first calculation unit 121 and the second calculation unit 122 performs calculations using a classifier that has undergone machine learning. This makes it possible to calculate the sensible temperature distribution based on the history in a short period of time.

(7) Modifications Modifications of the first embodiment will now be described.

As a modification of the first embodiment, the number of representative points of the environment included in the environmental information is not limited to multiple, and may be one. In other words, the number of representative points needs to be at least one. The environmental information includes information that represents the environment at at least one representative point of the space 7.

As another variation of the first embodiment, the environmental equipment 5 may include an air conditioner. The air conditioner is installed in the building 6 and adjusts the temperature of the space 7 in the building 6 by discharging warm or cold air into the space 7.

As yet another variation of embodiment 1, space 7 is not limited to being an interior space of building 6, but may be an open space.

As a modified example of the first embodiment, when livestock 9 present in the space of an abnormal environment is detected, the notification control unit 15 is not limited to controlling the notification device 21 to notify both the livestock 9 present in the space of an abnormal environment and the position of the livestock 9 present in the space of an abnormal environment. The notification control unit 15 may control the notification device 21 to notify only the livestock 9 present in the space of an abnormal environment, or may control the notification device 21 to notify only the position of the livestock 9 present in the space of an abnormal environment. In short, when livestock 9 present in the space of an abnormal environment is detected by the abnormality detection unit 124, it is preferable that the notification control unit 15 controls the notification device 21 to notify at least one of the livestock 9 present in the space of an abnormal environment and the position of the livestock 9 present in the space of an abnormal environment.

The notification device 21 notifies information according to instructions from the notification control unit 15, and therefore the notification device 21 is not limited to notifying both the livestock 9 present in the space with an abnormal environment and the position of the livestock 9 present in the space with an abnormal environment. The notification device 21 may only notify the livestock 9 present in the space with an abnormal environment, or may only notify the position of the livestock 9 present in the space with an abnormal environment. In short, it is preferable for the notification device 21 to notify at least one of the livestock 9 present in the space with an abnormal environment and the position of the livestock 9 present in the space with an abnormal environment.

In the first embodiment, as described above, the computational model (trained model) used in the processing unit 12 is generated by machine learning. The processing unit 12 may be implemented as any type of artificial intelligence or system. Here, the machine learning algorithm is, for example, a neural network. However, the machine learning algorithm is not limited to a neural network, and may be, for example, an eXtreme Gradient Boosting (XGB) regression, a random forest, a decision tree, a logistic regression, a support vector machine (SVM), a Naive Bayes classifier, or k-nearest neighbors. Furthermore, the machine learning algorithm may be, for example, a Gaussian Mixture Model (GMM), or k-means clustering.

In addition, in the first embodiment, the learning method is, as an example, supervised learning. However, the learning method is not limited to supervised learning, and may be unsupervised learning or reinforcement learning.

The sensible temperature calculation system according to each of the above modified examples also achieves the same effects as the sensible temperature calculation system 1 according to embodiment 1.

The subject of execution of the sensible temperature calculation system 1 or the sensible temperature calculation method in the present disclosure includes a computer system. The computer system is mainly composed of a processor and a memory as hardware. The processor executes a program recorded in the memory of the computer system, thereby realizing the function of the subject of execution of the sensible temperature calculation system 1 or the sensible temperature calculation method in the present disclosure. The program may be pre-recorded in the memory of the computer system, or may be provided through an electric communication line, or may be recorded and provided in a non-transitory recording medium such as a memory card, an optical disk, or a hard disk drive that can be read by the computer system. The processor of the computer system is composed of one or more electronic circuits including a semiconductor integrated circuit (IC) or a large-scale integrated circuit (LSI). The multiple electronic circuits may be integrated in one chip or distributed across multiple chips. The multiple chips may be integrated in one device or distributed across multiple devices.

In addition, in the first embodiment, the sensible temperature calculation system 1 includes an acquisition unit 11, a processing unit 12, an equipment control unit 13, a memory unit 14, and a notification control unit 15, but the acquisition unit 11, the equipment control unit 13, the memory unit 14, and the notification control unit 15 are not essential components of the sensible temperature calculation system 1. In other words, the sensible temperature calculation system 1 only needs to include the processing unit 12, and at least one of the acquisition unit 11, the equipment control unit 13, the memory unit 14, and the notification control unit 15 does not have to be included as a component of the sensible temperature calculation system 1.

The sensible temperature calculation system 1 may be realized by one device that fits into one housing, or may be realized by two or more devices. At least one of the acquisition unit 11, the processing unit 12, the equipment control unit 13, the storage unit 14, and the notification control unit 15 may be provided in a distributed manner with the remaining of the acquisition unit 11, the processing unit 12, the equipment control unit 13, the storage unit 14, and the notification control unit 15. For example, the processing unit 12 may be provided in a distributed manner with the equipment control unit 13. In addition, each function of the acquisition unit 11, the processing unit 12, the equipment control unit 13, the storage unit 14, and the notification control unit 15 may be provided in a distributed manner with multiple devices. For example, at least one of the first calculation unit 121, the second calculation unit 122, the tracking calculation unit 123, and the abnormality detection unit 124 may be provided in a distributed manner with the remaining of the first calculation unit 121, the second calculation unit 122, the tracking calculation unit 123, and the abnormality detection unit 124. At least a part of the functions of the sensible temperature calculation system 1 may be realized, for example, by the cloud (cloud computing).

(Embodiment 2)
Hereinafter, the control system according to the second embodiment will be described with reference to the drawings. Figures 5, 6, 7A, 7B, 9, and 10 referred to in the following embodiments are schematic diagrams, and the ratios of sizes and thicknesses of the components in the diagrams do not necessarily reflect the actual dimensional ratios.

(1) Control System The configuration of a control system 100 according to the second embodiment will be described with reference to the drawings.

As shown in Figs. 5 and 6, the control system 100 according to the second embodiment includes a plurality of baffle members 2A (three in the illustrated example), an environmental facility (ventilation facility) 5, and a control device 4. The control system 100 according to the second embodiment controls the wind speed of air in the internal space (space 7).

The control system 100 is a system that controls the wind speed of air in the internal space (space 7) of the building 6. The control system 100 is used in a barn or the like where livestock 9 are raised. The barn is, for example, a chicken barn where chickens are raised. However, the barn is not limited to being a chicken barn, and may be a pig barn where pigs are raised as livestock 9, or a cow barn where cows are raised as livestock 9.

(2) Building The building 6 in which the control system 100 is installed will be described with reference to the drawings.

As shown in Figs. 5 and 6, the building 6 includes a building body 61 having, for example, a rectangular parallelepiped shape. The building 6 also has an internal space (space 7). The building 6 also includes a control system 100.

In the example of FIG. 5, the building 6 is a livestock barn. When the building 6 is a livestock barn, the building body 61 is the livestock barn body. In the building 6, a large number of livestock 9 are raised in the internal space (space 7).

The building body 61 has two first side walls 62, 63 and two second side walls 64, 65. A plurality of baffle members 2A and environmental equipment (ventilation equipment) 5 are attached to the building body 61.

The two first side walls 62, 63 are, for example, rectangular and are arranged along the longitudinal direction D1 of the building 6. The two first side walls 62, 63 face each other in the lateral direction D2 of the building 6 through an internal space (space 7).

The two second side walls 64, 65 are, for example, rectangular and are arranged along the short direction D2 of the building 6. The two second side walls 64, 65 face each other in the long direction D1 of the building 6 through the internal space (space 7).

The internal space (space 7) is a space surrounded by the building body 61. More specifically, the internal space (space 7) is a space surrounded by two first side walls 62, 63 and two second side walls 64, 65.

The building 6 also has multiple (two in the illustrated example) air intakes 66 and an exhaust vent 67. Each of the multiple air intakes 66 draws air from the outside of the building 6 into the internal space (space 7). The exhaust vent 67 exhausts air from the internal space (space 7) to the outside of the building 6.

The multiple air intakes 66 (air intakes 661, 662) are provided at the lower ends of the first side walls 62, 63 along the longitudinal direction D1 of the building 6. More specifically, one air intake 661 is provided at the lower end of the first side wall 62 at the first end side (the second side wall 64 side) of the longitudinal direction D1. The other air intake 662 is provided at the lower end of the first side wall 63 at the first end side of the longitudinal direction D1. One air intake 661 and the other air intake 662 face each other in the transverse direction D2 of the building 6.

The exhaust vent 67 is provided on the second end side (the second side wall 65 side) of the building 6 in the longitudinal direction D1. More specifically, the exhaust vent 67 is provided near the center of the second side wall 65. The exhaust vent 67 may also be provided near the upper end of the second side wall 65.

The number of air intake ports 66 is not limited to two, and may be only one, or may be three or more. In other words, the number of air intake ports 66 must be one or more. The number of exhaust ports 67 is not limited to one, and may be two or more. In other words, the number of exhaust ports 67 must be one or more.

(3) Components of the Control System Each component of the control system 100 according to the second embodiment will be described below with reference to the drawings.

(3.1) Baffle Member As shown in Fig. 5 and Fig. 6, a plurality of baffle members 2A are provided between an air intake port 66 and an exhaust port 67 in the internal space (space 7) of the building 6. In the example of Fig. 5, the number of baffle members 2A is three. Each baffle member 2A is suspended from a ceiling 69 of the building 6 so that a space 73 is formed between a lower end 20A of the baffle member 2A and a floor surface 68 of the building 6. In other words, each baffle member 2A is suspended from the ceiling 69 in a range that does not touch the floor surface 68 of the building 6. Each baffle member 2A is formed, for example, of a translucent material or a transparent material.

Each of the multiple baffle members 2A is arranged to block a portion of the longitudinal direction D1 in the internal space (space 7). In other words, the multiple baffle members 2A block air from flowing along the longitudinal direction D1.

In the internal space (space 7), the wind speed of the air passing through the position where the baffle member 2A is installed is higher than the wind speed of the air passing through the position where the baffle member 2A is not installed. Also, the larger the space 73 between the floor surface 68 of the building 6 and the lower end 20A of the baffle member 2A, the lower the wind speed of the air passing through the space 73.

Each baffle member 2A in embodiment 2 is a plate installed in the interior space (space 7) of the building 6 so that its normal direction is along a direction (longitudinal direction D1) perpendicular to the height direction D3 of the building 6. This makes it difficult for the baffle member 2A to deform even when exposed to air, allowing the wind speed of the air to be stably controlled.

The multiple baffle members 2A include a first baffle member 21A, a second baffle member 22A, and a third baffle member 23A. The first baffle member 21A, the second baffle member 22A, and the third baffle member 23A are arranged in this order from the second side wall 64 side at intervals in the longitudinal direction D1 of the building 6. The first baffle member 21A is arranged closest to the air intake port 66 in the longitudinal direction D1 among the multiple baffle members 2A. On the other hand, the third baffle member 23A is arranged closest to the exhaust port 67 in the longitudinal direction D1 among the multiple baffle members 2A.

The baffle member 2A is positioned so that the wind speed is uniform in the region between the baffle member 2A and the exhaust port 67 in the internal space (space 7) of the building 6. In other words, the baffle member 2A is positioned so that the difference in wind speed between positions in the region between the baffle member 2A and the exhaust port 67 in the internal space (space 7) of the building 6 is reduced. This allows the heat in the internal space (space 7) of the building 6 to be smoothly discharged to the outside of the building 6.

Here, "uniform wind speed" means that the variation in wind speed is 1.0 m/s or less. More preferably, the variation in wind speed is 0.5 m/s or less. In addition, it is preferable that the variation in wind speed is 20% or less of the average wind speed.

As described above, three or more baffle members 2A are provided. In addition, the distance between two adjacent baffle members 2A among the three or more baffle members 2A is uniform. In other words, the distance L1 between the first baffle member 21A and the second baffle member 22A is the same as the distance L2 between the second baffle member 22A and the third baffle member 23A.

In addition, when there are three or more baffle members 2A, the distance between two adjacent baffle members 2A may be uneven. In other words, the distance L1 between the first baffle member 21A and the second baffle member 22A may be different from the distance L2 between the second baffle member 22A and the third baffle member 23A. This allows wind speed control to be performed according to the state of the building 6 and the internal space (space 7) of the building 6.

In addition, two or more baffle members 2A are provided, and the heights of the two or more baffle members 2A are uniform. In other words, the height T1 of the first baffle member 21A is the same as the height T2 of the second baffle member 22A and the height T3 of the third baffle member 23A. Here, the "height of the baffle member" refers to the height from the floor surface 68 of the building 6 to the lower end of the baffle member 2A. More specifically, the height T1 of the first baffle member 21A is the height from the floor surface 68 of the building 6 to the lower end 210A of the first baffle member 21A. The height T2 of the second baffle member 22A is the height from the floor surface 68 of the building 6 to the lower end 220A of the second baffle member 22A. The height T3 of the third baffle member 23A is the height from the floor surface 68 of the building 6 to the lower end 230A of the third baffle member 23A.

The heights of two or more baffle members 2A may be uneven. In other words, the height T1 of the first baffle member 21A, the height T2 of the second baffle member 22A, and the height T3 of the third baffle member 23A may be different from each other. Alternatively, any one of the height T1 of the first baffle member 21A, the height T2 of the second baffle member 22A, and the height T3 of the third baffle member 23A may be different from the remaining two. This allows wind speed control according to the state of the building 6 and the internal space (space 7) of the building 6. In particular, when a ventilation fan 52 is provided at the exhaust port 67, the air in the area close to the exhaust port 67 has higher kinetic energy than the air in the area close to the intake port 66. Therefore, even if the space 733 (see FIG. 7) between the third baffle member 23A and the floor surface 68 is large, the air passing through the space 733 has a higher wind speed than the air passing through the space 731 (see FIG. 7) between the first baffle member 21A and the floor surface 68 and the air passing through the space 732 (see FIG. 7) between the second baffle member 22A and the floor surface 68.

The number of baffle members 2A is not limited to three. The number of baffle members 2A may be only one, only two, or four or more. In short, it is sufficient for the control system 100 to be equipped with at least one baffle member 2A.

(3.2) Environmental equipment (ventilation equipment)
As shown in FIGS. 5 and 6 , the environmental equipment (ventilation equipment) 5 includes a plurality of (two in the illustrated example) opening/closing windows 51 and a plurality of (five in the illustrated example) ventilation fans 52 .

(3.2.1) Openable Windows The multiple openable windows 51 are provided in the air supply opening 66 of the building 6, as shown in Figures 5 and 6. More specifically, of the multiple openable windows 51 (openable windows 511, 512), one openable window 511 is provided in the air supply opening 661 of the first side wall 62 provided along the longitudinal direction D1, and the other openable window 512 is provided in the air supply opening 662 of the first side wall 63 provided along the longitudinal direction D1.

The multiple opening and closing windows 51 are also known as tunnel doors, and open and close by rotating up and down. When the opening and closing windows 51 are open, air can be let in from outside the building 6 through the air intake vent 66 into the interior space (space 7).

5 and 6 , the multiple ventilation fans 52 are provided at the exhaust port 67. More specifically, the multiple ventilation fans 52 are provided on the opposite side to the opening/closing window 51 in the longitudinal direction D1. That is, the multiple ventilation fans 52 are provided at the second side wall 65.

The multiple ventilation fans 52 are also arranged in a row in the short direction D2. More specifically, in the short direction D2, ventilation fans 521, 522, 523, 524, and 525 are arranged in this order from the first side wall 63 side.

The multiple ventilation fans 52 exhaust air from the internal space (space 7) of the building 6 to the outside of the building 6. More specifically, the multiple ventilation fans 52 are installed so that the air from the internal space (space 7) is exhausted in substantially the same direction. This allows air from the internal space (space 7) to be drawn in on the exhaust side and exhausted to the outside of the building 6.

(3.3) Control Device The control device 4 shown in Fig. 5 has a function of controlling the multiple ventilation fans 52. More specifically, the control device 4 individually controls the multiple ventilation fans 52. In addition, the control device 4 has a function of receiving an input of the outside air temperature outside the building 6.

The control device 4 controls the multiple ventilation fans 52 according to the outside air temperature input to the control device 4. More specifically, the control device 4 adjusts the number of ventilation fans 52 to be operated among the multiple ventilation fans 52 according to the outside air temperature.

Specifically, the higher the outside air temperature input to the control device 4, the more the control device 4 operates the number of ventilation fans 52 out of the multiple ventilation fans 52. On the other hand, the lower the outside air temperature input to the control device 4, the less the number of ventilation fans 52 that are operated out of the multiple ventilation fans 52. This makes it possible to maintain the air speed in the interior space (space 7) of the building 6 within a desired speed range, even if the outside air temperature outside the building 6 fluctuates.

The control device 4 may obtain the outside air temperature by manual input, or may obtain the outside air temperature by automatic input from an air temperature sensor installed near the outside of the building 6. When the control device 4 obtains the outside air temperature by manual input, the accuracy of the outside air temperature is often higher because a person can manually input a correction to the outside air temperature of the building 6. On the other hand, when the control device 4 obtains the outside air temperature by automatic input from an air temperature sensor, it becomes possible to automatically control the air speed in the internal space (space 7) 24 hours a day.

(4) Control Method The control method according to the second embodiment will be described below with reference to Figs. 7A and 7B. The control method according to the second embodiment is a method for controlling the wind speed of air in the internal space (space 7) of the building 6. Fig. 7A shows the distribution of wind speed by the control method according to the second embodiment. Fig. 7B shows the distribution of wind speed by a comparative example. The height from the floor surface 68 (see Fig. 6) of the building 6 to the lower end 20A (see Fig. 6) of each baffle member 2A is 1.5 m. The wind speeds shown in Figs. 7A and 7B are those at a position 300 mm above the floor surface 68.

As shown in FIG. 7B, the comparative example is an example in which the baffle member 2A is not provided in the internal space (space 7A) of the building 6A. In the comparative example, since the baffle member 2A is not provided, the wind speed of the air in the internal space (space 7A) is low. For example, in the main area of the internal space (space 7A), the wind speed of the air at a height of 300 mm from the floor surface 68 is about 1.0 m/s. Here, the "main area of the internal space (space 7A)" refers to the area of the internal space (space 7A) excluding the area in which the air intake 66 (see FIG. 5) and the exhaust 67 (see FIG. 5) are provided, and refers to the area near the center in the short direction D2. In other words, the areas at both ends in the short direction D2 are not included in the main area of the internal space (space 7A). When the building 6A is a livestock shed, the main area of the internal space (space 7A) is the area in which a large number of livestock 9 exist.

On the other hand, in the control method according to the second embodiment, as shown in FIG. 6, multiple baffle members 2A are provided. The multiple baffle members 2A are suspended from the ceiling 69 of the building 6 between the air intake 66 (see FIG. 5) and the exhaust 67 (see FIG. 5) in the internal space (space 7) of the building 6, so that there is a space 73 between the lower end 20A of the baffle member 2A and the floor surface 68 of the building 6. As described above, the air intake 66 is an opening through which air is supplied from the outside of the building 6 to the internal space (space 7). As described above, the exhaust 67 is an opening through which air is exhausted from the internal space (space 7) to the outside of the building 6.

In this case, in the space 73 in which the baffle member 2A is provided, the cross-sectional area of the space 73 becomes smaller than the cross-sectional area of the remaining space, so that the wind speed of the air passing through the space 73 becomes higher, as shown in FIG. 7A. More specifically, in the case of FIG. 7A, the wind speed of the air can be increased in the space between the first baffle member 21A closest to the air supply port 66 and the third baffle member 23A closest to the exhaust port 67 in the internal space (space 7) of the building 6. For example, in the main area of the internal space (space 7), the wind speed of the air at a height of 300 mm from the floor surface 68 is about 2.5 m/s. As a result, the wind speed of the air in the internal space (space 7) can be increased compared to when the baffle member 2A is not provided, so that the heat remaining in the internal space (space 7) can be easily discharged to the outside. Here, the "main area of the internal space (space 7)" refers to the area of the internal space (space 7) between the first baffle member 21A closest to the air intake vent 66 and the third baffle member 23A closest to the exhaust vent 67, and refers to the area near the center in the short direction D2. In other words, the areas at both ends in the short direction D2 are not included in the main area of the internal space (space 7). When the building 6 is a livestock shed, the main area of the internal space (space 7) is the area where many livestock 9 reside.

In the second embodiment, when the intake air taken in through the opening/closing window 51 is sucked out through the ventilation fan 52 and exhausted, a spiral air current is generated in the internal space (space 7). As this spiral air current travels from the opening/closing window 51 to the ventilation fan 52, it hits the lower end 20A of the baffle member 2A and increases in wind speed. It then loses speed before reaching the next baffle member 2A, but increases in wind speed when it hits the next baffle member 2A. This allows the spiral air current to be controlled to a substantially constant wind speed at any position within the internal space (space 7) of the long and narrow building 6.

For example, if building 6 is a chicken coop, the industry's chicken farmer training instruction manual states that a comfortable wind speed for chickens is around 3.0 to 4.0 m/s. For this reason, it is desirable for the wind speed in the interior space (space 7) to be kept within the above numerical range. In the example of Figure 7A, the air speed at a height of 300 mm from floor 68 increases to 1.0 m/s to 2.5 m/s. The height of 300 mm from floor 68 is close to the height of a cockscomb. This can increase the effect of cooling the chickens.

In this case, the multiple baffle members 2A can make the air speed uniform in the space between the first baffle member 21A and the third baffle member 23A in the internal space (space 7). In the example of FIG. 7B, the wind speed at a height of 300 mm from the floor surface 68 is 1.0 m/s to 2.0 m/s, whereas in the example of FIG. 7A, the wind speed at a height of 300 mm from the floor surface 68 is 2.5 m/s to 3.0 m/s. In the example of FIG. 7A, there is less variation in the wind speed compared to the example of FIG. 7B.

(5) Effects In the control system 100 according to the second embodiment, the baffle member 2A is suspended from the ceiling 69 of the building 6 so as to have a space 73 between the lower end 20A and the floor surface 68 of the building 6, and is provided in the interior space (space 7) of the building 6. This makes it possible to narrow the space 73 between the lower end 20A of the baffle member 2A and the floor surface 68, thereby increasing the wind speed when air passes through the space 73. As a result, it becomes easier to discharge heat retained in the interior space (space 7) of the building 6 to the outside of the building 6.

When the control system 100 is used in a barn for raising livestock 9, it is possible to reduce stress on the livestock 9 caused by heat retained in the internal space (space 7). In particular, since chickens are covered entirely in feathers and do not have sweat glands, when the livestock 9 is a chicken, it is important to expel heat retained in the internal space (space 7) to prevent the internal space (space 7) from becoming too hot.

In the control system 100 according to the second embodiment, the baffle member 2A is arranged so as to reduce the difference in wind speed between positions in the region between the baffle member 2A and the exhaust port 67. This allows the heat in the interior space (space 7) of the building 6 to be smoothly discharged to the outside of the building 6.

In the control system 100 according to the second embodiment, an opening/closing window 51 is provided in an air supply port 66 provided at the lower end of the first side walls 62, 63 along the longitudinal direction D1 of the building 6. This makes it possible to adjust the amount of air supplied from the air supply port 66 to the internal space (space 7) according to the opening/closing degree of the opening/closing window 51.

In the control system 100 according to the second embodiment, the spacing between two adjacent baffle members 2A may be uneven. This allows wind speed control according to the state of the building 6 and the interior space (space 7) of the building 6.

In the control system 100 according to the second embodiment, the heights of two or more baffle members 2A may be non-uniform. This allows wind speed control according to the state of the building 6 and the interior space (space 7) of the building 6.

In the control system 100 according to the second embodiment, a ventilation fan 52 that exhausts air from the internal space (space 7) to the outside of the building 6 is provided at the exhaust port 67. This allows air from the internal space (space 7) to be sucked in on the exhaust side and exhausted to the outside of the building 6.

In the control system 100 according to the second embodiment, the higher the outside temperature outside the building 6, the more ventilation fans 52 are operated, and the lower the outside temperature, the less ventilation fans 52 are operated. This allows the air speed in the interior space (space 7) of the building 6 to be maintained within a desired speed range, even if the outside temperature outside the building 6 fluctuates.

In the control system 100 according to the second embodiment, the building 6 is a livestock barn. This reduces the accumulation of heat even in the internal space (space 7) of the barn, thereby reducing the stress of the livestock 9 caused by the heat. As a result, a comfortable environment for raising the livestock 9 can be provided.

There is a system that irradiates light with wavelengths between 550 and 650 nm, which is more effective at preventing the temperature rise inside the poultry house (the interior space of the building) and the poultry (the building) than infrared rays, but this system does not have the function of expelling heat from inside the poultry house. In other words, this system does not have the function of controlling the air flow inside the poultry house.

The control system 100 according to the second embodiment can increase the air velocity in the interior space (space 7) of the building 6.

(6) Modifications Modifications of the second embodiment will now be described.

As a first modification of the second embodiment, the control system 100a may further include a plurality of (three in the illustrated example) hanging mechanisms 9A as shown in FIG. 8. The plurality of hanging mechanisms 9A can move the plurality of baffle members 2A in the height direction D3 (see FIG. 6) of the building 6 (see FIG. 6).

In the case of variant 1, each baffle member 2A is a flexible member such as a vinyl sheet. Examples of each baffle member 2A include structures such as roll curtains and drop curtains.

The multiple hanging mechanisms 9A correspond one-to-one to the multiple baffle members 2A. More specifically, the multiple hanging mechanisms 9A include a first hanging mechanism 91A, a second hanging mechanism 92A, and a third hanging mechanism 93A. The first hanging mechanism 91A corresponds to the first baffle member 21A, the second hanging mechanism 92A corresponds to the second baffle member 22A, and the third hanging mechanism 93A corresponds to the third baffle member 23A. Each hanging mechanism 9A has the function of moving the corresponding baffle member 2A in the height direction D3 of the building 6. When the baffle member 2A is a roll curtain, each hanging mechanism 9A can change the position of the lower end 20A (see FIG. 6) of the baffle member 2A in the height direction D3 by rolling up the corresponding baffle member 2A. When the baffle member 2A has a structure similar to a stage curtain, each hanging mechanism 9A can change the position of the lower end 20A of the baffle member 2A in the height direction D3 by moving the lower end of the corresponding baffle member 2A up and down.

In addition, in variant 1, the control system 100a is equipped with a control device 4a as shown in FIG. 8 instead of the control device 4.

The control device 4a has a function to control multiple ventilation fans 52 (five in the illustrated example) as well as a function to control multiple hanging mechanisms 9A. More specifically, the control device 4a is configured to control the multiple hanging mechanisms 9A individually. When changing the height of the lower end 20A (see FIG. 6) of each baffle member 2A, the control device 4a controls the multiple hanging mechanisms 9A individually.

As described above, in the control system 100a according to the first modified example, a hanging mechanism 9A is provided that can move the baffle member 2A in the height direction D3 (see FIG. 6) of the building 6 (see FIG. 6). This allows the height of the baffle member 2A to be easily changed. In other words, the height from the floor surface 68 (see FIG. 6) of the building 6 to the lower end 20A of the baffle member 2A can be easily changed. As a result, the arrangement of the baffle member 2A can be adjusted according to the season, time, or temperature of the internal space (space 7) (see FIG. 6) of the building 6. For example, if livestock 9 are present in the internal space (space 7), the height of the baffle member 2A can be adjusted according to the breeding conditions of the livestock 9.

As a second modification of the second embodiment, the control system 100b may include an environmental facility (ventilation facility) 5b as shown in FIG. 9, instead of the environmental facility (ventilation facility) 5 (see FIG. 5).

Instead of the multiple ventilation fans 52 (see FIG. 5) provided at the exhaust port 67, the environmental equipment (ventilation equipment) 5b includes multiple (six in the illustrated example) ventilation fans 52b provided at the air intake port 66. For example, the same number of multiple ventilation fans 52b are provided at the two air intake ports 66. More specifically, at the air intake port 661, ventilation fans 52b, 522b, and 523b are lined up in this order in the longitudinal direction D1. At the air intake port 662, ventilation fans 524b, 525b, and 526b are lined up in this order in the longitudinal direction D1. The multiple ventilation fans 52b supply air from outside the building 6 to the interior space (space 7).

The environmental equipment (ventilation equipment) 5b also includes an opening/closing window 51b provided at the exhaust port 67, instead of the opening/closing window 51 (see FIG. 5) provided at the air intake port 66.

The control device 4b of the control system 100b according to the second modification has a function of controlling a plurality of ventilation fans 52b. More specifically, the control device 4b controls the plurality of ventilation fans 52b individually. Note that, regarding the control device 4b, a description of the same functions as those of the control device 4 of the second embodiment will be omitted.

In the control system 100b according to the second modification, a ventilation fan 52b that supplies air from outside the building 6 to the internal space (space 7) is provided at the air intake port 66. This allows air in the internal space (space 7) to be exhausted by being pushed out from the exhaust port 67 by drawing air in through the air intake port 66.

As a third modification of the second embodiment, the control system 100c may include an environmental facility (ventilation facility) 5c as shown in FIG. 10. The environmental facility (ventilation facility) 5c includes both a plurality of ventilation fans 52 provided at the exhaust port 67 and a plurality of ventilation fans 52b provided at the intake port 66.

The control device 4c of the control system 100c according to the third modification has a function of controlling the multiple ventilation fans 52 and the multiple ventilation fans 52b. More specifically, the control device 4c individually controls the multiple ventilation fans 52 and the multiple ventilation fans 52b. Note that, regarding the control device 4c, a description of the same functions as the control device 4 of the second embodiment will be omitted.

In the control system 100c according to the third modification, ventilation fans 52, 52b that supply air from outside the building 6 to the internal space (space 7) are provided at both the air inlet 66 and the exhaust port 67. As a result, by drawing air in from the air inlet 66, the air in the internal space (space 7) can be pushed out and exhausted from the exhaust port 67, and by drawing air in from the exhaust port 67, the air in the internal space (space 7) can be sucked in and exhausted to the outside. As a result, the capacity for air intake and exhaust can be increased.

As another variation of the second embodiment, the baffle member 2A is removable from the building 6. This allows the baffle member 2A to be attached to or removed from the building 6 depending on the need for the baffle member 2A. For example, if livestock 9 are present in the internal space (space 7), the baffle member 2A can be attached to or removed from the building 6 depending on the breeding status of the livestock 9.

As another variation of embodiment 2, the baffle member 2A may be a flexible vinyl sheet.

The building 6 is not limited to a livestock barn, but may be a building in which people reside. The building 6 may be, for example, a gymnasium in a school or the like. In general, it is desirable to avoid constantly blowing wind on people. However, for example, when exercising in a gymnasium, it is preferable to install at least one baffle member 2A and set the air speed to the desired speed at any height (at the height of a person's head) in the internal space (space 7) of the building 6 to prevent heatstroke.

As another variation of the second embodiment, a mechanism may be provided for moving each of the multiple baffle members 2A in the longitudinal direction D1 of the building 6. This makes it easy to change the spacing between adjacent baffle members 2A.

As another variation of embodiment 2, the air intake vent 66 may be provided in the second side wall 64 of the building 6, and the air exhaust vent 67 may be provided in the first side walls 62 and 63 of the building 6.

The control systems according to the above-mentioned modified examples also achieve the same effects as the control system 100 according to the second embodiment.

The above-described embodiments and modifications are merely a part of the various embodiments and modifications of the present invention. Furthermore, the embodiments and modifications can be modified in various ways depending on the design, etc., as long as the object of the present invention can be achieved.

An environmental control system (2) according to a fourteenth aspect includes a sensible temperature calculation system (1) according to any one of the first to tenth aspects, and a control system (100; 100a; 100b; 100c). The control system (100; 100a; 100b; 100c) is used together with an environmental facility (5; 5b; 5c) that ventilates an internal space (space 7) of a building (6). The control system (100; 100a; 100b; 100c) controls the wind speed of air that is supplied from an air supply port (66) of the building (6) and exhausted from an exhaust port (67) of the building (6) to the outside of the building (6) through the internal space (space 7). The control system (100; 100a; 100b; 100c) includes at least one baffle member (2A).

The control device (4; 4a; 4c) receives an input of the outside air temperature outside the building (6). The higher the outside air temperature inputted to the control device (4; 4a; 4c), the more the control device (4; 4a; 4c) operates the number of ventilation fans (52) out of the plurality of ventilation fans (52). The lower the outside air temperature inputted to the control device (4; 4a; 4c), the more the control device (4; 4a; 4c) operates the number of ventilation fans (52) out of the plurality of ventilation fans (52).

According to the environmental control system (2) of the twentieth aspect, even if the outside air temperature outside the building (6) fluctuates, the wind speed of the air in the interior space (space 7) of the building (6) can be maintained within a desired speed range.

According to the environmental control system (2) of the twenty-third aspect, the baffle member (2A) can be attached to the building (6) or detached from the building (6) depending on the need for the baffle member (2A). For example, if livestock (9) are present in the internal space (space 7), the baffle member (2A) can be attached to the building (6) or detached from the building (6) depending on the rearing status of the livestock (9).

The livestock shed (building 6) according to the 24th aspect includes an environmental control system (2) according to any one of the 14th to 23rd aspects and a building body (61). A baffle member (2A) and environmental equipment (5; 5b; 5c) are attached to the building body (61).

According to the livestock barn (building 6) of the 24th aspect, the control system (100; 100a; 100b; 100c) can narrow the space (73) between the lower end (20A) of the baffle member (2A) and the floor surface (68), thereby increasing the wind speed when air passes through the space (73). As a result, heat retained in the internal space (space 7) of the building (6) can be easily discharged to the outside of the building (6).

When the control system (100; 100a; 100b; 100c) is used in a barn for raising livestock (9), it is possible to reduce stress on the livestock (9) caused by heat retained in the internal space (space 7). In particular, since chickens are covered entirely in feathers and do not have sweat glands, when the livestock (9) is a chicken, it is important to expel heat retained in the internal space (space 7) to prevent the internal space (space 7) from becoming too hot.

The control method according to the 25th aspect is a control method for controlling the wind speed of air supplied from an air supply port (66) of a building (6) and exhausted from an exhaust port (67) of the building (6) to the outside of the building (6) through an internal space (space 7). In the above control method, a baffle member (2A) is suspended from a ceiling (69) of the building (6) between the air supply port (66) and the exhaust port (67) in the internal space (space 7) so that there is a space between the lower end (20A) of the baffle member (2A) and the floor surface (68) of the building (6).

According to the control method of the 25th aspect, the space (73) between the lower end (20A) of the baffle member (2A) and the floor surface (68) can be narrowed, so that the wind speed can be increased when the air passes through the space (73). As a result, heat that is trapped in the internal space (space 7) of the building (6) can be easily discharged to the outside of the building (6).

The control system (100; 100a; 100b; 100c) according to the 26th aspect is used together with an environmental facility (5; 5b; 5c) that ventilates an internal space (space 7) of a building (6), and controls the wind speed of air that is supplied from an air supply port (66) of the building (6) and exhausted from an exhaust port (67) of the building (6) to the outside of the building (6) through the internal space (space 7). The control system (100; 100a; 100b; 100c) includes at least one baffle member (2A). The baffle member (2A) is provided between the air supply port (66) and the exhaust port (67) in the internal space (space 7), and is suspended from the ceiling (69) of the building (6) so as to have a space (73) between its lower end (20A) and the floor surface (68) of the building (6).
