Description

  The present invention relates to a house cultivation system, and relates to a technique that enables advanced growth management of agricultural products.

  Conventionally, in order to cultivate crops such as tropical fruits with different environmental conditions and cultivation in cold regions, such as greenhouses, greenhouses, greenhouses, greenhouses, etc. A simple house is set up on the area), and house cultivation is carried out widely to grow crops and the like inside the house.

  In house cultivation, since the planting area can be isolated from the outside by the house, even if external environmental conditions such as temperature and humidity are inappropriate, the inside of the house can be made an environment suitable for crops. However, even if the top of the planting area is covered with a house, the planting area is connected to the outside of the house through the ground, so the outside temperature is transmitted from the ground to the inside of the house, and the inside of the house is maintained at an appropriate temperature. It can be difficult. In addition, groundwater and pests may enter the planting area from the ground and adversely affect the growth of crops.

  Therefore, for example, in Patent Document 1, a recess is provided in farmland under the house, and the recess is covered with a sealed water partition wall in which a vinyl sheet is covered with a heat insulating material such as polystyrene foam, and the recessed portion is covered with a sealed water partition wall. A method for isolating the farmland under the house from the outside world by housing the cultivated soil is disclosed. However, since the area of the planting area is generally large, it is too impractical to completely isolate the planting area from the outside world.

  On the other hand, Patent Document 2 proposes a maintenance unit that can keep the soil of the planting area, prevent the ingress of groundwater, and the like by surrounding only the periphery of the planting area. The maintenance unit is composed of a heat insulating material made of a flat plate-like resin, a drainage basin made of a pipe having a split along the longitudinal direction, and a water permeable block made of a strip-like porous resin. In the state where the lower end of the heat insulating material and the water permeable block are elastically sandwiched between the drainage basins, it is embedded in the ground so as to surround the planting area.

  In addition, in order to perform advanced growth management of agricultural products, a growth condition measurement device equipped with a temperature sensor, humidity sensor, etc. is installed in the vicinity of the plant to be managed, and the measurement results obtained by each sensor are wirelessly communicated. Alternatively, a system for transmitting to a centralized management device by wired communication is disclosed (Patent Document 3).

  The centralized management device manages the growth state of the plant by calculating and displaying the optimum amount of irrigation, and warning when the measurement result deviates from the allowable range.

JP-A-5-260857 JP 11-46596 A JP 2012-187074 A

  Since the maintenance unit of Patent Document 2 is configured by combining a plurality of members, it takes time to install. Furthermore, since the heat insulating material is only sandwiched in the drainage basin, when the amount of groundwater increases, it may be lifted by its buoyancy and may not function normally.

  The growth condition measuring apparatus of Patent Document 3 has room for improvement because changes in temperature and moisture in the ground are not taken into consideration. On the ground, temperature sensors can be visually observed and can be easily installed and maintained, so stable measurements can be performed for a long time. However, when underground, the temperature sensors cannot be visually observed and installation and maintenance are difficult. Therefore, it is not easy to measure stably for a long time.

  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a house cultivation system that can maintain not only the ground of a planting area but also the ground in a state suitable for the growth of agricultural crops and enables advanced growth management of the agricultural crops.

  The house cultivation system according to the present invention includes a house installed on the farmland so as to cover the planting area, and a heat insulation embedded in the ground along the side wall of the house so that the upper end is exposed to the ground. A wall, an underground measuring instrument embedded in the ground, and a power transmission device that transmits a measurement value measured by the underground measuring instrument to the terminal device. The heat retaining wall has a panel made of a plurality of foamed plastics connected in parallel, and the panel has a floating prevention portion that protrudes from the side surface and is buried in the ground. And at least 1 said underground measuring device is arrange | positioned in the vicinity of the lower end of the said heat insulating wall.

  That is, according to this house cultivation system, since not only the ground of the planting area but also the ground is simply isolated from the outside by the heat insulation wall, more advanced growth management can be performed. Since the panels that make up the insulation wall have an anti-floating part, even if the moisture in the soil increases due to heavy rain, etc., the panel can be prevented from rising due to the soil that accumulates on it. It can be stably held at the installed position for a period.

  And since the underground measuring instrument is located near the lower end of the heat insulation wall, the influence of the outside world on the planting area can be grasped by crossing the lower end of the heat insulation wall, before the adverse effects on the crops. It becomes possible to deal with. And since the measured value measured with an underground measuring instrument can be transmitted to a terminal device, it can grasp | ascertain the growth conditions of agricultural products through a terminal device even in the place away from a house. Therefore, advanced growth management of agricultural products becomes possible, and stable and efficient cultivation can be realized.

  Specifically, it is preferable that the terminal device is configured to be able to wirelessly communicate with the power transmission device via a network, and the measurement value can be transmitted to the terminal device in real time.

  By doing so, it is possible to adjust the temperature, humidity, irrigation amount, etc. inside the house quickly and appropriately, so that more advanced growth management of crops becomes possible.

  More specifically, the panel has a through-hole penetrating from the upper end to the lower end thereof, and the underground measuring instrument is arranged in the vicinity of the lower end of the heat retaining wall through the through-hole. Good.

  Then, the underground measuring instrument can be stably installed at an appropriate position in the ground. In addition, since the underground measuring instrument is supported by the heat insulating wall, positional displacement is prevented and high-precision measurement can be performed for a long period of time. Since the upper through-hole is exposed to the ground, the underground measuring instrument can be wired safely and easily, and can be easily replaced even if a failure occurs.

  In this case, the panel further has a lateral hole that opens on a side surface thereof and communicates with the through hole, and the second underground measuring instrument is disposed on the side of the heat retaining wall through the lateral hole. It is good to do so.

  Then, it will be possible to measure underground changes around the crops. Moreover, since it becomes possible to analyze the time-dependent change of the measured value from which a depth differs, the advanced change prediction in the underground of a planting area can also be performed now.

  Moreover, the said panel can also be made to have the heat insulation adjustment part which can be inserted or extracted from the upper end part.

  Then, the thermal insulation effect of each panel can be easily adjusted, so by adjusting the thermal insulation effect according to the location of the thermal insulation wall based on the measurement value of the underground measuring instrument, stable crops can be obtained throughout the planting area. Growth management can be performed.

  Still further, the heat retaining wall has a heat transfer body attached to a lower end portion of the panel, and a water passage space facing the heat transfer body is formed at the lower end portion of the panel, and the upper end portion of the panel Further, a water intake port and a water discharge port communicating with both ends of the water flow space may be formed, and hot water or cold water may be passed through the water flow space through the water intake port and the water discharge port.

  Then, the underground temperature can be adjusted, and the underground temperature of the planting area can be stably maintained at an appropriate temperature.

  In this case, in particular, it is preferable that the temperature of water passed through the water flow space can be adjusted based on a measurement value measured by the underground measuring instrument.

  If it does so, since the underground temperature of a planting area can be automatically hold | maintained at suitable temperature, the higher growth management of agricultural products will be attained.

  According to the house cultivation system of the present invention, not only on the ground of the planting area but also in the ground can be stably maintained in a state suitable for the growth of the crop, so that advanced growth management of the crop can be performed. .

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. However, the following description is merely illustrative in nature and does not limit the present invention, its application, or its use.

(Overall configuration of house cultivation system)
The whole structure of the house cultivation system 1 of this embodiment is shown in FIG.1 and FIG.2. The house cultivation system 1 includes a house 10, a heat insulating wall 30, a power transmission device 50, a terminal device 70, various measuring instruments 91, 92, 93, and the like, and is configured to perform advanced growth management of agricultural products. . This house cultivation system 1 is suitable for a cold region such as Hokkaido where outdoor cultivation is difficult in winter. However, even if it is not a cold region, such as a tropical fruit, It is also suitable for extremely hot areas that exceed the growth temperature in summer and areas where the temperature difference is high.

  The house 10 is a simple hut-like structure installed on the farmland so as to cover a planting area PA where crops are planted, such as a greenhouse 10 or a greenhouse. In this embodiment, the greenhouse 10 is exemplified. doing. The greenhouse 10 is composed of a plurality of steel pipes, and by attaching a sheet having excellent weather resistance to the framework, the greenhouse 10 includes a rectangular side wall portion 10a surrounding the four sides and a roof portion 10b having an arched cross section. Is formed.

  Since the space above the planting area PA is blocked from the outside by the installation of the house 10, an environment suitable for the crop planted in the planting area PA can be realized inside the house 10. In order to maintain the environment, the house 10 is provided with an attachment device 13 including a heating device such as a boiler and a heater, a cooling device such as a cooler, and a ventilation device such as a duct and a fan. In addition, in order to supply water to the crops, an irrigation device 14 for supplying water to the planting area PA is also installed in the house 10.

  The heat insulating wall 30 insulates between the planting area PA and the outside world, conducts heat from the outside world to the planting area PA through the ground, and invades the planting area PA from the ground of water and pests. In order to prevent the above, it is embedded in the ground along the inside of the side wall of the house 10 so as to surround the planting area PA. In order to prevent outside air and water from entering the planting area PA along the ground surface, the heat retaining wall 30 is embedded so that the upper end portion thereof is exposed to the ground.

  The depth of embedding the heat retaining wall 30 is preferably deep, but is set in a range of approximately 400 mm to 700 mm in consideration of ease of handling and environmental conditions. For example, in the case of a cold region, it is preferable to embed to a depth equal to or greater than the freezing depth (the depth from the ground surface where freezing does not occur).

  The power transmission device 50 according to the present embodiment includes a transmission device 51, a host computer 52, and the like. The transmission device 51 is installed in the vicinity of the house 10 and is electrically connected to various measuring instruments 91, 92, 93 installed in the house 10. The transmission device 51 has a function of transmitting measurement values measured by these measuring instruments 91, 92, and 93 to the host computer 52 in real time by wired communication or wireless communication.

  The host computer 52 is a well-known computer system including hardware such as a CPU, a memory, and a monitor, and software installed in these hardware. In this embodiment, the host computer 52 is a desktop type. A high-performance personal computer is exemplified. The host computer 52 includes an input / output device and communication software that enable bidirectional wireless communication with a portable terminal device 70 such as a smartphone or a tablet terminal via the Internet (an example of a network) IN. Is provided.

  The measuring instrument is a device that measures environmental conditions such as temperature, humidity, and pH that are important for the growth of crops planted in the planting area PA, and is installed as necessary. The measuring instrument is composed of a ground measuring instrument installed on the ground and an underground measuring instrument buried in the ground. In the present embodiment, a thermometer 91 and a hygrometer 92 are exemplified as the ground measuring instrument, and a temperature sensor and a moisture sensor are exemplified as the underground measuring instrument (also collectively referred to as the underground sensor 93).

  The underground sensors 93 embedded in the ground are arranged at a plurality of locations around the planting area PA, such as the four corners of the planting area PA and intermediate portions thereof. Furthermore, these underground sensors 93 are also arranged at a plurality of locations having different depths. Specifically, the underground sensor 93 is disposed in the vicinity of the lower end of the heat retaining wall 30 and in the vicinity of the inner side of the heat retaining wall 30.

  The underground sensor 93 (first underground sensor 93a) disposed in the vicinity of the lower end of the heat insulation wall 30 causes the temperature change in the ground due to heat transmitted to the planting area PA across the heat insulation wall 30 and the heat insulation wall 30 to The moisture change in the ground that crosses and enters the planting area PA can be measured. And the underground temperature change and water | moisture content change around agricultural products can be measured with the underground sensor 93 (2nd underground sensor 93b) arrange | positioned in the inner side vicinity of the heat insulation wall 30. FIG.

  By comparing the measured values of these underground sensors 93 arranged at a plurality of locations around the planting area PA, it is possible to grasp in detail the growth conditions for each location of the planting area PA. Then, by analyzing the change over time of the measured values of the first underground sensor 93a and the second underground sensor 93b, it is possible to predict the underground temperature change and moisture change of the planting area PA.

  Measurement values such as the house temperature measured by the thermometer 91, the house humidity measured by the hygrometer 92, the underground temperature and underground moisture measured by the underground sensor 93 are transmitted at a constant cycle. 51 and sent to the host computer 52 in real time. These measured values sent to the host computer 52 are stored in a storage device so that data processing and data analysis can be performed as necessary.

  By accessing the host computer 52 from the terminal device 70, it is possible to browse the measurement value data and analysis results stored in the host computer 52. In addition, by setting the terminal device 70 in a state where it can communicate with the host computer 52, the measurement value transmitted from the transmission device 51 to the host computer 52 can be transmitted to the terminal device 70 in real time. .

  As a result, the crop growth manager can always grasp the growth conditions of the crop in real time through the terminal device 70 even in a place away from the house 10, and the temperature, humidity, and irrigation amount inside the house 10. Can be adjusted quickly and appropriately, so that advanced growth management of agricultural products becomes possible, and stable and efficient cultivation can be realized.

  In particular, in this house cultivation system 1, since the soil of the planting area PA is simply isolated from the outside by installing the heat insulating wall 30, more advanced growth management can be performed.

  That is, the movement of heat and moisture through the soil to the planting area PA is performed by crossing the lower end of the heat insulating wall 30, and after the lower end of the heat insulating wall 30 is crossed, the influence is planted where the crop is planted. There is a time lag before reaching the surface layer of the area PA. Therefore, by grasping the measurement value of the first underground sensor 93a in real time, it becomes possible to cope with the adverse effects on the crops.

  For example, when the upper limit value and the lower limit value of the crop management temperature are set in the memory of the host computer 52 and the measured value of the underground sensor 93 reaches the lower limit temperature or the upper limit temperature, the terminal device 70 is used. If a warning is given to the crop growth manager, stable growth management can be performed without overlooking abnormalities.

  In addition, the heat retaining wall 30 is devised so that the installation can be performed easily and the underground measuring instrument can be installed easily and appropriately.

(Insulating wall 30)
FIG. 3 shows the heat insulating wall 30 of the present embodiment. The heat retaining wall 30 is configured by connecting a plurality of rectangular plate-like panels 31 made of foamed plastic such as polystyrene foam (EPS) in parallel and arranging them in a rectangular frame shape around the planting area PA. . Each panel 31 has, for example, a thickness of 10 cm to 50 cm, a horizontal dimension of 1 m to 2 m, and a vertical dimension of 0.7 m to 1 m.

  The side end surface 31b of each panel 31 is provided with dovetail-shaped connecting portions 32a and 32b. Specifically, a dovetail groove 32a having an inverted triangular shape in cross section is formed in one side end face 31b so as to be recessed from the upper end face 31c to the lower end face 31d, and the other side end face 31b has an inverted cross section. A triangular ant tenon 32b is formed so as to protrude from the upper end surface 31c to the lower end surface 31d. By fitting the dovetail 32b of the other panel 31 into the dovetail groove 32a of the adjacent one panel 31, each panel 31 can be connected in parallel and its length can be freely adjusted. Yes.

  Since the panel 31 is made of foamed plastic, it has excellent heat insulation, is lightweight and easy to handle, and is a general-purpose product and inexpensive, so there is a great cost merit. Moreover, since it can be easily processed, the shape and size can be adjusted as needed on site, such as cutting off unnecessary parts, and the workability is excellent.

  Further, a floating prevention portion 33 is formed on the side surface 31 a of the panel 31. Specifically, a strip-like portion that protrudes laterally from the lower end portion of one side surface 31 a of the panel 31 embedded in the ground and extends between both side end surfaces 31 b and 31 b of the panel 31 is integrated with the panel 31. Is formed.

  When the moisture in the soil increases due to heavy rain or the like, the foamed plastic panel 31 has a high buoyancy, so that the heat retaining wall 30 may be broken up due to floating. On the other hand, in this heat retaining wall 30, since the floating prevention part 33 is formed, it is possible to prevent the panel 31 from being lifted by the soil deposited thereon, and the heat retaining wall 30 is placed at a position where it has been installed for a long time. It can be held stably.

  A protrusion 34 that protrudes upward and extends in parallel with the side surface 31 a of the panel 31 is formed at the tip of the floating prevention portion 33. The lateral protrusion of the panel 31 can be prevented by the protrusion 34. In addition, when the insulated wall 30 is buried, if the crushed stone or the like is laid on the floating prevention portion 33, the insulated wall 30 can be held more stably.

  A through hole 35 used for installing an underground measuring instrument is formed at the side end of the panel 31. As shown in FIG. 4, the through hole 35 is a cylindrical long hole penetrating from the upper end surface 31 c of the panel 31 to the lower end surface 31 d. Further, the panel 31 is formed with a lateral hole 36 that opens to a predetermined height position from the lower end surface 31 d of one side surface 31 a and communicates with the through hole 35.

  The first underground sensor 93a and the second underground sensor 93b are disposed at predetermined positions in the ground through the through holes 35 and the lateral holes 36. Specifically, the first underground sensor 93a is disposed through the through hole 35 so as to protrude downward from the lower end of the heat retaining wall 30, and laterally from the side surface 31a facing the planting area PA of the heat retaining wall 30. 2nd underground sensor 93b is arrange | positioned through the horizontal hole 36 so that it may protrude.

  Since the 1st underground sensor 93a and the 2nd underground sensor 93b can be installed through the through-hole 35 and the horizontal hole 36 which were formed in the predetermined position of the heat insulation wall 30, it is stably in the appropriate position in the ground. Can be installed. Since the 1st underground sensor 93a and the 2nd underground sensor 93b are supported by the heat insulating wall 30, position shift is prevented and highly accurate measurement can be performed for a long period of time. Since the upper through hole 35 is exposed to the ground, the wiring of the first underground sensor 93a and the second underground sensor 93b can be safely and easily performed along the upper end of the heat retaining wall 30, and a failure occurs. Can be easily replaced.

  The through hole 35 can also be used to support the ground measuring instrument, and the thermometer 91 and the hygrometer 92 of the present embodiment are arranged at a predetermined height by being attached to a support column that is inserted into the through hole 35 and fixed. ing.

(Modification 1)
FIG. 5 shows a first modification of the heat retaining wall 30. The heat retaining wall 30A of the present modification is different from the heat retaining wall 30 described above in that the adjustment of the heat insulation effect can be easily performed. In other words, the panel 31 constituting the heat retaining wall 30A has the heat insulation adjusting portion 40 that can be inserted and removed from the upper end portion thereof. In addition, since the other structure of this modification is the same as embodiment, about that description, it abbreviate | omits (the modification 2 is also the same).

  The heat insulation adjustment part 40 of this embodiment is comprised by the insertion space 41 and the insertion panel 42. FIG. The insertion space 41 is a space that is rectangular in a side view extending between both side surfaces 31 a and 31 a of the panel 31, and has a slit-like opening on the upper end surface 31 c of the panel 31. The insertion panel 42 is a rectangular plate-like foamed plastic member that fits into the insertion space 41. The insertion space 41 and the insertion panel 42 can be easily formed by cutting out the insertion panel 42 from a portion where the insertion space 41 of the panel 31 is formed.

  By pulling out the insertion panel 42 from the insertion space 41, the thickness of the panel 31 can be substantially reduced, and the heat insulation effect of the heat retaining wall 30 can be reduced. Since the insertion panel 42 is made of foamed plastic, its thickness and shape can be easily processed. Therefore, the crop growth manager inserts the insertion panel 42 whose thickness is adjusted into the insertion space 41 based on the measurement value of the sensor, or inserts the insertion panel 42 whose size is adjusted into the insertion space 41. By inserting it into a part, the heat insulation effect of each heat retaining wall 30 can be easily adjusted, and stable crop growth management can be performed over the entire planting area PA.

(Modification 2)
6 and 7 show a second modification of the heat retaining wall 30. FIG. The heat retaining wall 30B of this modification is different from the heat retaining wall 30 described above in that the temperature adjustment in the ground is possible.

  That is, the heat retaining wall 30B has a strip-shaped metal plate 45 (an example of a heat transfer body) in addition to the panel 31 made of foamed plastic. The metal plate 45 is attached to the lower end surface 31d of the panel 31 by welding. A water passing space 46 facing the metal plate 45 is formed at the lower end portion of the panel 31 between both end portions of the panel 31.

  A water intake 47 and a water outlet 48 are opened on the upper end surface 31 c of the panel 31. Both ends of the water flow space 46 communicate with each of the water intake 47 and the water outlet 48 through a pair of water passages 49. If the water intake 47 of one adjacent panel 31 and the water outlet 48 of the other panel 31 are connected by piping, the water flow space 46 of each panel 31 can be connected and water can flow. Further, water can be passed only to a specific panel 31.

  In the house cultivation system 1 of this modification, a temperature-controlled water supply device that can circulate and supply hot water or cold water is installed as the attachment device 13. With this temperature control water supply device, the temperature-adjusted hot water or cold water can be passed through the water intake space 47 of each panel 31 through the water intake 47 and the water outlet 48.

  Therefore, the crop growth manager can adjust the underground temperature of the planting area PA based on the measurement value of the underground sensor 93. For example, if the growth manager determines that the underground temperature of the planting area PA may be lower than the appropriate temperature based on the measured values of the first underground sensor 93a and the second underground sensor 93b transmitted, The administrator may operate the temperature control water supply device to pass the warm water through the water space 46. By doing so, the temperature of warm water is transmitted to the soil via the metal plate 45 and the soil around the planting area PA is warmed, so that the underground temperature of the planting area PA can be maintained at an appropriate temperature.

  Similarly, when the growth manager determines that the underground temperature of the planting area PA may exceed the appropriate temperature based on the measured values of the first underground sensor 93a and the second underground sensor 93b that are transmitted, The growth manager may operate the temperature control water supply device to pass cold water through the water space 46. By doing so, the temperature of cold water is transmitted to the soil via the metal plate 45, and the soil around the planting area PA is cooled, so that the underground temperature of the planting area PA can be maintained at an appropriate temperature.

  Since the heat of the outside world is transmitted to the planting area PA across the lower end of the heat retaining wall 30, by adjusting the temperature at the lower end of the heat retaining wall 30, heat such as hot water can be directly applied. The underground temperature of the planting area PA can be efficiently maintained at an appropriate temperature.

  In the case of using the heat retaining wall 30, in particular, it is preferable that the temperature of the water passed through the water passing space 46 can be automatically adjusted based on the measurement value measured by the underground sensor 93.

  Specifically, the temperature control water supply device is electrically connected to the host computer 52 via the transmission device 51, and the operation of the temperature control water supply device is based on the temperature measurement value measured by the underground sensor 93. Configure to be controllable. For example, when the upper limit value and the lower limit value of the crop management temperature are set in the memory of the host computer 52 and the measured value of the underground sensor 93 reaches the lower limit temperature, the temperature control water supply device is operated to When the measured value of the temperature sensor reaches the upper limit temperature, the temperature control water supply device is operated to control the supply of cold water.

  Then, since the underground temperature of the planting area PA can be automatically maintained at an appropriate temperature, advanced growth management of the crop can be performed, and stable crop cultivation can be performed.

  Similarly, the irrigation device 14 may be controlled based on the moisture measurement value measured by the underground sensor 93. If it does so, since the water | moisture content in the ground of the planting area PA can be automatically hold | maintained in an appropriate quantity, the more advanced growth management of agricultural crops will be attained.

  In addition, the house cultivation system 1 concerning this invention is not limited to embodiment mentioned above, The other various structure is included. For example, the electric transmission device 50 may directly transmit the measurement value from the transmission device 51 to the terminal device 70 without using the host computer 52. The underground measuring instrument may be a PH sensor. The horizontal holes 36 may be provided on both sides of the side surface 31 a of the panel 31, and the underground sensor 93 may be installed outside the heat retaining wall 30. The heat insulation adjusting unit 40 may be provided on the panel 31 of the heat retaining wall 30B.
