Description

The present invention relates to a wind measuring device that detects the magnitude and direction of a wind force and measures the wind speed, the wind direction, and the like.

At farm sites such as living spaces, industrial equipment, and cultivation facilities, "wind speed" is an important environmental factor and also affects productivity. Furthermore, information on the "wind direction" from which direction the wind is blowing is important for understanding the environment. For example, in a living space, it is better to be able to grasp the flow direction of harmful substances such as cigarette smoke. Even in industrial equipment, it is necessary to pay attention to the direction of the wind in clean rooms. Furthermore, in data centers and server rooms, which play a central role in ICT and cloud computing, if wind airflow is not properly managed, the server will not be cooled properly, limiting processing speed. Will receive.

Further, unlike the outdoor environment, the wind speed in these spaces is often 1 m / s or less, and the installation location is limited, so that the wind measuring device needs to be small. Further, even outdoors, there is an increasing demand for miniaturization and cost reduction of sensors, and a wind measuring device that meets these needs is required.

By the way, various methods have been conventionally proposed as wind measuring devices for measuring wind speed and direction. For example, a so-called weathercock, which is generally used in outdoor meteorological measurement, is known to have feathers on the leeward side due to the force of the wind. In particular, the Japan Meteorological Agency and outdoor meteorological measurements use what is called an airplane type equipped with a propeller for wind speed detection.

In addition, an ultrasonic method that obtains the wind speed and direction from the transmission speed of ultrasonic waves has been put into practical use. This is a method of simultaneously measuring wind speeds in a plurality of directions, deriving a vector from the plurality of wind speeds, and obtaining a wind direction. To calculate the wind direction, an ultrasonic oscillator and a receiver with at least two axes are required, and if three sets of these are used for measurement on three axes, a three-dimensional wind direction can also be obtained.

Further, a method in which a propeller type anemometer is combined in three directions to obtain a three-dimensional wind direction is also used in some cases.

However, these conventional wind measuring devices are large in size because they require a space of 20 cm square or more, and the cost of the device is also high. In addition, since the above wind measuring devices other than the ultrasonic type utilize the fact that a force proportional to the cube of the wind speed is applied to the object, it is difficult to measure in the light wind speed range, or it is difficult to make a difference due to the difference in wind speed. On the contrary, when the design was optimized for the breeze speed range, the range was over when placed in an environment with a slightly strong wind speed range. On the other hand, among the above, only the ultrasonic type can satisfactorily detect a breeze speed of 1 m / s or less, but in order to improve the resolution, the ultrasonic type also has to increase the frequency used or the oscillator to receive. It was necessary to increase the distance between the vessels.

Therefore, apart from the above-mentioned method, a thermal wind measuring device has been put into practical use. This method has the features that it is easy to miniaturize, the structure is relatively simple, and the breeze speed can be measured. As an example of practical use, a method of calculating the wind direction by combining three Pt self-heating wind speed sensors having directivity and utilizing the difference in sensitivity due to directivity has been adopted and is also commercially available. .. However, since this method uses three thin platinum resistors, it has problems that it has low weather resistance against mechanical impact and corrosiveness, and that it requires labor for manufacturing.
Therefore, the present inventor has invented the ones shown in Patent Documents 1 to 3 as a structure and manufacturing method of a wind measuring device having high cost, miniaturization, and robustness by overcoming these problems, and applied for a patent. ing.

However, as a problem of the thermal type, it is necessary to keep the detection portion warm, which causes a problem that the sensor does not operate unless a constant heat energy source is supplied to the sensor. As a result, when a battery is used as a power source, continuous operation cannot be performed for a long time, and in order to perform continuous operation, it is necessary to prepare a power source such as a commercial power source as an energy source so that electricity can be stably received for a long period of time. There is. This problem imposes restrictions on the installation and operation of equipment, and imposes restrictions on the IoT and smart community realization that are expected in the future.

In addition to the above methods, pitot tubes used in aircraft and differential pressure type flow meters for measuring fluids such as pipes have been put into practical use, but these may be used when the flow direction is fixed. , For fluids with known flow paths, not suitable for measurements where the flow direction is uncertain or the flow direction is unpredictable.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a wind measuring device capable of accurately measuring a wind speed and a wind direction with a simple configuration.

In order to achieve the above object, the wind measuring device according to the present invention has a detector that receives wind, a transmission member that supports the detector and transmits the force of the wind received by the detector, and the transmission member. It is characterized by being provided with a detection sensor that detects the magnitude of the force of the incoming wind.

According to this, it is possible to easily and surely detect the magnitude of the wind force with a simple configuration consisting of a detector, a transmission member and a detection sensor, and it is possible to accurately measure the wind speed and direction. Become.

Further, the detector may be formed in a sphere. According to this, since the wind has no directivity to the wind from all directions, up, down, left and right, the magnitude of the wind force from all directions can be detected.

Further, the detector may be formed in such a manner that a plurality of thin rod-shaped members extend radially. According to this, when the detector receives a strong wind, it is possible to prevent an excessive force from being applied to the transmission member and the detection sensor by passing the wind between the rod-shaped members.

Further, the transmission member is composed of a rod-shaped member extending in the axial direction, and the detector may be provided at the tip end portion and the detection sensor may be provided at the base end portion. It may be arranged on the peripheral surface side of the base end portion of the member. According to this, it is possible to easily and surely detect the magnitude of the wind force by making the configuration even simpler.

Further, the transmission member includes a rod-shaped member extending in the axial direction and a plurality of leg members provided at the base end portions of the rod-shaped member, and a detection sensor may be provided at the base end portion of each leg member. .. According to this, the direction of the wind can be measured by synthesizing the detection results of the magnitude of the wind force by each detection sensor provided at the base end portion of each leg member.

Further, the transmission member is composed of a rod-shaped member extending in the axial direction and a flat plate member provided at a base end portion of the rod-shaped member, and a plurality of detection sensors may be provided on the back surface of the flat plate member. The transmission member is made of a flat plate member extending in the plane direction, and the detector may be provided on the front surface and a plurality of the detection sensors may be provided on the back surface. According to this, the direction of the wind can be measured by synthesizing the detection results of the magnitude of the wind force by each detection sensor provided on the back surface of the flat plate member.

Further, the rod-shaped member may be made of a flexible material. According to this, since the force transmitted to the detection sensor can be attenuated by bending according to the wind force received by the deductor, it can be applied in a wide wind speed range from a weak wind speed environment to a strong wind speed environment.

Further, a measuring unit that measures the wind speed and / or the wind direction based on the magnitude of the wind force detected by the detection sensor may be provided. According to this, it is possible to accurately measure the wind speed and / or the wind direction based on the magnitude of the wind force detected by the detection sensor.

According to the present invention, it is possible to easily and surely detect the magnitude of the wind force by using a simple configuration consisting of a detector, a transmission member and a detection sensor, and it is possible to accurately measure the wind speed, the wind direction, and the like. It becomes.

Therefore, it is possible to provide a small and inexpensive wind measuring device for a situation where a wind speed or a wind direction is required in a living space, an industrial facility, an agricultural site such as a cultivation facility, or the like.

In addition, detection devices such as piezo elements that detect pressure and force do not require a large amount of power to save power, so they can be used in environments with limited power capacity such as chemical batteries, and energy harvesting such as solar cells and vibration power generation. The device can also operate in a power environment where the energy is complete within the device.

<First Embodiment>
Next, a first embodiment of the wind measuring device (hereinafter referred to as the present device) according to the present invention will be described with reference to FIG.

This device includes a detector 1 that receives wind, a transmission member 2 that transmits wind force, and a detection sensor 3 that detects wind force.

The detector 1 is formed in a sphere and has a shape that does not have directivity with respect to wind from all directions, up, down, left, and right. Therefore, when the detector 1 receives the wind from a certain direction, the detector 1 receives the force of the wind while flowing the wind along the surface of the sphere.

The transmission member 2 is made of a flexible resin or metal rod-shaped member extending in the axial direction, and a detector 1 is provided at a tip portion 2a and a detection sensor 3 is provided at a base end portion 2b. .. The transmission member 2 transmits the wind force received by the detector 1 to the detection sensor 3. Specifically, when the detector 1 receives wind, the transmission member 2 bends with the connection portion with the detection sensor 3 as a fulcrum, so that the base end portion 2b of the transmission member 2 is pulled in the Z-axis direction. A pushing force acts, and the tensile force and the pushing pressure are transmitted to the detection sensor 3 as a wind force.

The detection sensor 3 is formed on a flat plate having a rectangular shape in a plan view, and a transmission member 2 is erected at the center of the front surface, and the back surface is fixed to a fixed object such as a housing. The detection sensor 3 includes a conversion element such as a piezo element for detecting the magnitude of the wind force transmitted from the transmission member 2 and converting the magnitude of the wind force into an electric signal. In the present embodiment, the detection sensor 3 outputs a positive value when the base end portion 2b of the transmission member 2 is pulled in the positive direction of the Z axis, and negative when the transmission member 2 is pushed in the negative direction of the Z axis. Output the value.

Thus, when the wind flows in the lateral direction of the X-axis or the Y-axis and the detector 1 receives the wind in the lateral direction of the X-axis or the Y-axis, the transmission member 2 bends with the connection portion with the detection sensor 3 as a fulcrum. As a result, the base end portion 2b of the transmission member 2 is in a state of being pulled in the positive direction of the Z axis, so that the detection sensor 3 detects the tensile force at that time as a wind force and outputs a positive value.

<Second embodiment>
Next, a second embodiment of the present device according to the present invention will be described with reference to FIGS. 2 to 3. In the following, only the configurations different from the above-described embodiment will be described, and the same configurations will be omitted and the same reference numerals will be given.

In the present embodiment, the base end portion 2b of the transmission member 2 is directly fixed to a solid object G such as a housing. Therefore, when the detector 1 receives wind, the transmission member 2 bends with the connection portion with the solid object G as a fulcrum, so that the base end portion 2b of the transmission member 2 is pushed in the X-axis direction or the Y-axis direction. A force acts and the pressing force is transmitted to the detection sensor 3 as a wind force.

Further, the detection sensor 3 includes two first and second detection sensors 3A and 3B formed in a rectangular parallelepiped. The first and second detection sensors 3A and 3B are provided via the connecting members 41 and 42 in the X-axis direction and the Y-axis direction on the peripheral surface side of the base end portion 2b of the transmission member 2, respectively. These first and second detection sensors 3A and 3B are piezo elements for detecting the magnitude of the wind force transmitted from the transmission member 2 and converting the magnitude of the wind force into an electric signal. It consists of conversion elements such as. In the present embodiment, the first detection sensor 3A outputs a positive value when pulled in the positive direction of the X-axis by the base end portion 2b of the transmission member 2 via the connecting member 41, and outputs a positive value in the negative direction of the X-axis. When pressed, a negative value is output. On the other hand, when the second detection sensor 3B is pushed by the base end portion 2b of the transmission member 2 via the connecting member 42 in the positive direction of the Y axis, it outputs a positive value, and when it is pulled in the negative direction of the X axis. Output a negative value.

Thus, when the wind flows in the lateral direction of the X-axis and the Y-axis and the detector 1 receives the wind in the lateral direction of the X-axis and the Y-axis, the transmission member 2 bends with the connection portion with the fixed object G as a fulcrum. As a result, the base end portion 2b of the transmission member 2 is pushed in the X-axis and Y-axis directions via the connecting members 41 and 42, and the first and second detection sensors 3A and 3B are pushed accordingly. The first and second detection sensors 3A and 3B detect the pressing force and the tensile force at that time as the wind force and output a positive value or a negative value. At this time, since the first detection sensor 3A detects the wind force in the X-axis direction and the second detection sensor 3B detects the wind force in the Y-axis direction, the X-axis direction by these first detection sensors 3A The total wind force and direction (direction of the two-dimensional plane in the X-axis-Y-axis direction) is measured by synthesizing the wind force of the above and the wind force in the Y-axis direction by the second detection sensor 3B. Can be done.

In the present embodiment, the first detection sensor 3A and the second detection sensor 3B are provided separately, but the first detection sensor 3A and the second detection sensor 3B are integrated into one. The forces of the two winds may be converted into electrical signals.

<Third embodiment>
Next, a third embodiment of the present device according to the present invention will be described with reference to FIGS. 4 to 5.

In the present embodiment, the transmission member 2 is attached to a first transmission member 21 made of a rod-shaped member made of flexible resin or metal extending in the axial direction, and a base end portion of the first transmission member 21. It is composed of a second transmission member 22 made of a flexible resin or metal leg member provided. The second transmission member 22 is composed of three transmission members 22A, 22B, and 22C, each extending diagonally downward from the base end portion of the first transmission member 21 at an angle of 120 degrees in a plan view. A detection sensor 3 (3A, 3B, 3C) is provided at the base end portion 2b. Therefore, when the detector 1 receives wind, the transmission member 2 bends with the connection portion with the detection sensor 3 as a fulcrum, so that the base end portion 2b of the second transmission member 22 is pulled in the Z-axis direction. , Pushing force acts, and those tensile force and pushing force are transmitted to the detection sensor 3 as wind force.

Is erected, and the back surface is fixed to a fixed object such as a housing. The detection sensor 3 (3A, 3B, 3C) detects the magnitude of the wind force transmitted from the transmission member 2, and converts the magnitude of the wind force into an electric signal such as a piezo element. Consists of conversion elements. In the present embodiment, the detection sensor 3 (3A, 3B, 3C) outputs a positive value when the base end portion 2b of the second transmission member 22 (22A, 22B, 22C) is pulled in the positive direction of the Z axis. Then, when the base end portion 2b of the second transmission member 22 (22A, 22B, 22C) is pushed in the negative direction of the Z axis, a negative value is output.

Thus, when the wind flows in a predetermined direction and the detector 1 receives the wind in a predetermined direction, the base end portion 2b of the second transmission member 22 (22A, 22B, 22C) is pulled in the positive direction of the Z axis. The detection sensor 3 (3A, 3B, 3C) detects the tensile force and pressing force at that time as the force of the wind and sets a positive value or a negative value. Output each. Further, by synthesizing the wind force in the Z-axis direction of these detection sensors 3 (3A, 3B, 3C), the total wind force and direction (three-dimensional direction in the X-axis-Y-axis-Z-axis direction) can be obtained. Can be measured.

For example, as shown in FIG. 5A, when the wind flows in the positive direction of the Y-axis and the detector 1 receives the wind in the positive direction of the Y-axis, the base end portion 2b of the second transmission member 22C has the Z-axis. Since the state is pushed in the negative direction of, the detection sensor 3C detects the pushing pressure at that time as the force of the wind and outputs a negative value. On the other hand, since the base end portions 2b of the second transmission members 22A and 22B are in a state of being pulled in the positive direction of the Z axis, the detection sensors 3A and 3B detect the tensile force at that time as the wind force and are positive. Outputs the value of. By synthesizing the wind force in the Z-axis direction by these detection sensors 3 (3A, 3B, 3C), the total wind force and direction (positive direction of the Y-axis) can be measured.

Further, for example, as shown in FIG. 5B, when the wind flows in the negative direction of the Y axis and the detector 1 receives the wind in the negative direction of the Y axis, the base end portions of the second transmission members 22A and 22B Since 2b is in a state of being pushed in the negative direction of the Z axis, the detection sensors 3A and 3B detect the pushing pressure at that time as a wind force and output a negative value. On the other hand, since the base end portion 2b of the second transmission member 22C is in a state of being pulled in the positive direction of the Z axis, the detection sensor 3C detects the tensile force at that time as a wind force and outputs a positive value. To do. By synthesizing the wind force in the Z-axis direction by these detection sensors 3 (3A, 3B, 3C), the total wind force and direction (negative direction in the Y-axis) can be measured.

Further, for example, as shown in FIG. 5C, when the wind flows in the positive direction of the X-axis and the detector 1 receives the wind in the positive direction of the X-axis, the base end portion 2b of the second transmission member 22B is moved. Since the Z-axis is pushed in the negative direction, the second detection sensor 3B detects the pushing pressure at that time as a wind force and outputs a negative value. On the other hand, since the base end portion 2b of the second transmission member 22A is in a state of being pulled in the positive direction of the Z axis, the detection sensor 3A detects the tensile force at that time as a wind force and outputs a positive value. To do. Since the base end portion 2b of the second transmission member 22C is neither pushed nor pulled, the detection sensor 3C outputs a neutral value (± 0). By synthesizing the wind force in the Z-axis direction by these detection sensors 3 (3A, 3B, 3C), the total wind force and direction (positive direction of the X-axis) can be measured.

Further, for example, as shown in FIG. 5D, when the wind flows in the negative direction of the Z axis and the detector 1 receives the wind in the negative direction of the Z axis, each of the second transmission members 22A, 22B, and 22C. Since the base end portion 2b is in a state of being pushed in the negative direction of the Z axis, the detection sensors 3A, 3B, and 3C detect the pressing force at that time as a wind force and output the same negative value. .. By synthesizing the wind force in the Z-axis direction by these detection sensors 3 (3A, 3B, 3C), the total wind force and direction (negative direction in the Z-axis) can be measured.

Further, for example, as shown in FIG. 5E, when the wind flows in the positive direction of the Z axis and the detector 1 receives the wind in the positive direction of the Z axis, each of the second transmission members 22A, 22B, and 22C. Since the base end portion 2b is in a state of being pulled in the positive direction of the Z axis, the detection sensors 3A, 3B, and 3C detect the tensile force at that time as a wind force and output the same positive value. .. By synthesizing the wind force in the Z-axis direction by these detection sensors 3 (3A, 3B, 3C), the total wind force and direction (positive direction of the Z-axis) can be measured.

<Fourth Embodiment>

It is composed of a member 22. In the second transmission member 22, the first transmission member 21 is erected from the central portion of the front surface, and the detection sensor 3 is provided on the back surface. Therefore, when the detector 1 receives the wind, the first transmission member 21 bends with the connecting portion with the second transmission member 22 as a fulcrum, so that each portion on the plane of the second transmission member 22 becomes Z. Forces that are pulled or pushed in the axial direction act, and these tensile forces and pushing pressures are transmitted to the detection sensor 3 as wind forces.

As shown in FIG. 6B, the detection sensor 3 is composed of three detection sensors 3A, 3B, and 3C formed in a disk shape, and each is along the peripheral edge of the back surface of the second transmission member 22. It is provided and is arranged at an angle of 120 degrees with respect to the central portion of the second transmission member 22.

Can be measured.

In the present embodiment, the transmission member 2 is composed of a first transmission member 21 made of a rod-shaped member and a second transmission member 22 made of a flat plate member, but as shown in FIG. 7, the flat plate member It may consist of only.

<Fifth Embodiment>
Next, a fifth embodiment of the present device according to the present invention will be described with reference to FIG.

According to this, when the detector 1 receives a strong wind, it is possible to prevent an excessive force from being applied to the transmission member 2 and the detection sensor 3 by passing the wind between the rod-shaped members 11.

In the present embodiment, the rod-shaped member 11 includes not only a rigid material having a certain diameter but also a material made of hair and the like.

In each of the above embodiments, as shown in FIG. 9, a measuring unit that measures the wind speed and / or the wind direction may be provided based on the magnitude of the wind force detected by the detection sensor 3.

However, when the transmission member 2 is made of a flexible member, the force transmitted to the detection sensor 3 can be attenuated by bending according to the wind force received by the detector, so that the wind speed environment can be changed from a weak wind speed environment to a strong wind speed environment. It can be applied in a wide range of wind speeds.

Further, although the detection sensor 3 uses 1 to 3 detection sensors 3, 4 or more detection sensors 3 may be used. When three detection sensors 3 (3A, 3B, 3C) are used, each detection sensor 3 (3A, 3B, 3C) is arranged so as to form an angle of 120 degrees from the center, but other detection sensors 3 (3A, 3B, 3C) are used. It may be an arrangement. However, when three detection sensors 3 (3A, 3B, 3C) are provided, if they are arranged so as not to line up in a straight line, the magnitude and direction of the wind can be measured with high accuracy.

Although the embodiments of the present invention have been described above with reference to the drawings, the present invention is not limited to those of the illustrated embodiments. Various modifications and modifications can be made to the illustrated embodiment within the same range as the present invention or within the same range.
