Description

Technical Field

[0001] The utility model relates to the technical field of environmental parameter detection, in particular to a wind speed and direction detection device. Background Art

[0002] Wind is a common natural phenomenon caused by solar radiation heat. The air in different places on the earth's surface is different in temperature, causing it to flow and form wind. From the perspective of meteorology, wind mainly refers to the horizontal component of air movement. Because wind is a vector, it is divided into wind speed and wind direction. Wind speed is the horizontal distance that air moves per unit time, based on the international unit of meters per second; wind direction refers to the direction from which the wind blows, generally expressed in sixteen-position method. The test of wind speed and direction has wide and important applications in many fields such as experimental research, weather forecasting, power station monitoring, navigation, and military. In the prior art, anemometers are generally divided into three categories: the first category is a mechanical rotating wind cup and a sensor with a wind direction arrow, the second category is anemometers based on ultrasonic principles, and the third category is to use the wind field to dissipate local heat on metal sheets, judge the temperature of metal sheets at different parts, and then know the size and direction of the wind. The three types of wind speed and direction detection devices in the prior art all have corresponding problems, among which: (1) the mechanical anemometer and wind vane are separated and rely on a mechanical rotating structure for detection, which is subject to wear and tear, is greatly affected by the environment, requires regular maintenance, and is costly; (2) the ultrasonic anemometer has no mechanical wear, but has the disadvantage of being large in size, and rain, snow, frost, fog, sand and dust, etc., will affect the accuracy of the measurement results; (3) the disadvantage of the hot wire anemometer is that it has high requirements for the use environment, is not suitable for high temperature, high humidity and low temperature environments, requires frequent calibration, cannot measure wind direction, and has a single function. Utility Model Content

[0003] The utility model aims to provide a wind speed and direction detection device, which can improve detection accuracy, prolong service life, increase the scope of use, and reduce operating costs.

[0004] The embodiment of the utility model is achieved as follows:

[0005] In a first aspect, the utility model provides a wind speed and direction detection device, comprising:

[0006] A carrying shell, a processor and a plurality of atmospheric pressure sensors, wherein the processor and the plurality of atmospheric pressure sensors are both mounted on the carrying shell, the processor is simultaneously communicatively connected with the plurality of atmospheric pressure sensors, and each of the atmospheric pressure sensors is used to obtain wind pressure.

[0007] In an optional embodiment, the multiple atmospheric pressure sensors include a first atmospheric pressure sensor and a second atmospheric pressure sensor; the carrying shell is provided with a windproof cavity connected to the outside world, and the first atmospheric pressure sensor is arranged in the windproof cavity to obtain a reference atmospheric pressure of the external environment; the second atmospheric pressure sensor is installed on the outside of the carrying shell to obtain wind pressure.

[0008] Based on the above scheme, by placing the first atmospheric pressure sensor in the windproof cavity, the first atmospheric pressure sensor is not affected by whether there is wind in the external environment, and the pressure value obtained is the reference value in the current environment, so that the values ​​obtained by the first atmospheric pressure sensor in different environments can be used as a reference for other atmospheric pressure sensors. For example, when the value of the second atmospheric pressure sensor in a certain direction changes, the value of the second atmospheric pressure sensor in the direction increases, and the environmental value obtained by the second atmospheric pressure sensor minus the reference value can be used to obtain the wind speed in the current environment.

[0009] In an optional embodiment, there are multiple second atmospheric pressure sensors, and the multiple second atmospheric pressure sensors are arranged at intervals in the circumferential direction of the carrying shell.

[0010] Based on the above solution, by setting up multiple second atmospheric pressure sensors, the wind speed blowing from different directions can be obtained, thereby expanding the scope of use.

[0011] In an optional embodiment, the number of the second atmospheric pressure sensors is four, and the four second atmospheric pressure sensors are evenly spaced and arranged in the circumferential direction of the carrying shell to correspond to four directions of east, south, west and north during operation.

[0012] Based on the above scheme, by setting four second atmospheric pressure sensors, each of the four second atmospheric pressure sensors can operate independently and can obtain wind speeds in four directions. When the wind direction is opposite to the position of the four second atmospheric pressure sensors, that is, when the wind is blowing from the east, south, west or north, the corresponding wind speed can be obtained by subtracting the environmental value obtained by the second atmospheric pressure sensor at the corresponding position from the reference value obtained by the first atmospheric pressure sensor. When the wind blows from between two adjacent second atmospheric pressure sensors, the wind pressure detected by the two adjacent second atmospheric pressure sensors increases. The value obtained by one of the second atmospheric pressure sensors is A, and the value obtained by the other second atmospheric pressure sensor is B. The actual wind speed is set to O, and the pressure differences between the two second atmospheric pressure sensors and the first atmospheric pressure sensor are △A and △B respectively. According to the Pythagorean theorem, the actual wind speed is O^ 2 =(△A)^ 2 +(△B)^ 2, and the wind speed is obtained by taking the square root. Further, the angle between △A and O, or the angle between △B and O can be calculated according to the sine function or the cosine function, so as to obtain the wind direction.

[0013] In an optional embodiment, the wind speed and direction detection device also includes a base and a driver, the base is used to be fixed to the ground surface, the driver is installed on the base, and the driver is connected to the supporting shell to drive the supporting shell to rotate around a preset axis, wherein, in the working state, the preset axis extends vertically.

[0014] Based on the above scheme, in the process of detecting wind speed, the driver can drive the carrying shell to rotate, thereby driving the second atmospheric pressure sensor to rotate, so that the second atmospheric pressure sensor obtains multiple environmental values ​​of wind speed in a week. When the second atmospheric pressure sensor is rotated to be directly opposite to the wind direction, the value obtained by the second atmospheric pressure sensor is the required environmental value. That is, the environmental values ​​obtained by rotating the second atmospheric pressure sensor for one week are compared, the largest environmental value is selected, and the environmental value is subtracted from the reference value to obtain the wind speed. The detection is convenient and accurate.

[0015] In an optional embodiment, the wind speed and direction detection device further includes an angle sensor or a gyroscope, and the angle sensor or the gyroscope is mounted on the supporting shell and is used to obtain the rotation angle of the rotating shaft.

[0016] Based on the above scheme, the angle of the second atmospheric pressure sensor from the initial position to the maximum environmental value is obtained through an angle sensor or a gyroscope, so that the wind direction can be known, and the detection is convenient and fast.

[0017] In an optional embodiment, the wind speed and direction detection device also includes an electronic compass or a magnetic sensor communicatively connected to the processor, and the electronic compass or the magnetic sensor is installed on the carrier shell, and the electronic compass or the magnetic sensor is used to obtain direction data; the direction data is combined with the rotation angle obtained by the angle sensor to obtain the wind direction.

[0018] Based on the above scheme, direction data can be obtained through an electronic compass or a magnetic sensor; then the rotation angle obtained by the angle sensor is used to match the direction data and the rotation angle data, and the wind direction is calculated through a known calculation formula to improve the accuracy of wind direction measurement.

[0019] In an optional embodiment, the supporting shell includes a main shell and an enclosure installed at the bottom of the main shell, and a side of the enclosure facing away from the main shell is set to be an opening, and the opening is used to connect to the external environment; the enclosure cooperates with the main shell to define the wind shelter cavity, and the first atmospheric pressure sensor is installed on the main shell.

[0020] Based on the above solution, the structure of the bearing shell is simple, and the windproof cavity is arranged at the bottom of the bearing shell. The airflow in the windproof cavity is less affected by the external environment, which can improve the accuracy of the wind speed measurement result.

[0021] In an optional embodiment, the wind speed and direction detection device further includes a temperature and humidity sensor communicatively connected to the processor, the temperature and humidity sensor is connected to the carrying shell, and the temperature and humidity sensor is used to obtain ambient temperature and humidity.

[0022] Based on the above solution, the ambient temperature and humidity can be acquired in real time, thereby obtaining more comprehensive environmental parameters.

[0023] The beneficial effects of the embodiments of the utility model are:

[0024] In summary, the wind speed and direction detection device provided in this embodiment is provided with a plurality of atmospheric pressure sensors. When there is wind, the atmospheric pressure sensors can obtain wind pressure, and the wind speed is calculated according to the wind pressure obtained by the atmospheric pressure sensors, which is convenient and quick. Since the atmospheric pressure sensor itself does not need to realize measurement through the rotation or extrusion of mechanical parts when working, there is no wear, and the measurement precision and accuracy are high.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] In the prior art, there are various wind speed and direction detection devices. Mechanical detection devices are subject to wear during operation, resulting in reduced measurement precision and poor accuracy. Ultrasonic anemometers have no mechanical wear, but are greatly affected by environmental factors and have poor measurement results. Hot wire anemometers are not suitable for high temperature and high humidity environments and low temperature environments, and cannot measure wind direction and have a single function.

[0039] In view of this, the designer provides a wind speed and direction detection device that can obtain wind speed and direction with high precision and accuracy, is less affected by environmental factors, and has a wide range of uses.

[0040] In this embodiment, the wind speed and direction detection device includes a carrier shell 100, a processor 200 and multiple atmospheric pressure sensors. The processor 200 and the multiple atmospheric pressure sensors are all installed on the carrier shell 100. The processor 200 is simultaneously communicated with the multiple atmospheric pressure sensors, and each atmospheric pressure sensor is used to obtain wind pressure.

[0041] Based on the above, the working principle of the wind speed and direction detection device provided in this embodiment is as follows:

[0042] The bearing shell 100 is used to position multiple atmospheric pressure sensors in the external environment, and the positions of the multiple atmospheric pressure sensors can be adjusted according to the needs, and the east, west, north or south directions can be used as references, which is conducive to the subsequent detection of wind speed and wind direction. In the actual operation process, when there is wind, the atmospheric pressure sensor can obtain the wind pressure, and the wind speed is calculated according to the wind pressure obtained by the atmospheric pressure sensor, which is convenient and fast. Since the atmospheric pressure sensor does not need to realize measurement through the rotation or extrusion of mechanical parts when working, there is no wear, and the measurement precision and accuracy are high.

[0043] The following embodiments illustrate the details of the wind speed and direction detection device provided by the present invention by way of examples.

[0044] Please combine Figure 1In this embodiment, optionally, the plurality of atmospheric pressure sensors include a first atmospheric pressure sensor 300 and a second atmospheric pressure sensor 400; the bearing shell 100 is provided with a windproof cavity 101 connected to the outside, the first atmospheric pressure sensor 300 is arranged in the windproof cavity 101, and is used to obtain the reference atmospheric pressure of the external environment; the second atmospheric pressure sensor 400 is installed outside the bearing shell 100, and is used to obtain the wind pressure. By arranging the first atmospheric pressure sensor 300 in the windproof cavity 101, the first atmospheric pressure sensor 300 is not affected by whether there is wind in the external environment, and the pressure value obtained is the reference value in the current environment, so that the values ​​obtained by the first atmospheric pressure sensor 300 in different environments can be used as a reference for other atmospheric pressure sensors. For example, when the value of the second atmospheric pressure sensor 400 in a certain direction changes, the value of the second atmospheric pressure sensor 400 in the direction increases, and the wind speed in the current environment can be obtained by subtracting the reference value from the environmental value obtained by the second atmospheric pressure sensor 400.

[0045] It should be noted that there are multiple second atmospheric pressure sensors 400, which are arranged at intervals in the circumferential direction of the carrying shell 100. By providing multiple second atmospheric pressure sensors 400, wind speeds blowing from different directions can be obtained, thereby expanding the scope of use.

[0046] Please combine Figure 2 For example, in an optional embodiment, the number of the second atmospheric pressure sensors 400 is four, and the four second atmospheric pressure sensors 400 are evenly spaced and arranged in the circumferential direction of the carrier shell 100 to correspond to the four directions of southeast, northwest, and northeast during operation. By setting four second atmospheric pressure sensors 400, each of the four second atmospheric pressure sensors 400 can operate independently and can obtain wind speeds in four directions. When the wind direction is directly opposite to the position of the four second atmospheric pressure sensors 400, that is, when the wind is blowing from the east, south, west, or north, the corresponding wind speed can be obtained by subtracting the environmental value obtained by the second atmospheric pressure sensor 400 at the corresponding position from the reference value obtained by the first atmospheric pressure sensor 300. When the wind blows from between two adjacent second atmospheric pressure sensors 400, the wind pressure detected by the two adjacent second atmospheric pressure sensors 400 increases, the value obtained by one second atmospheric pressure sensor 400 is A, and the value obtained by the other second atmospheric pressure sensor 400 is B. The actual wind speed is set to O, and the pressure difference between the two second atmospheric pressure sensors 400 and the first atmospheric pressure sensor 300 is △A and △B respectively. According to the Pythagorean theorem, the actual wind speed O^2=(△A)^2+(△B)^2, so the wind speed is obtained by square root calculation. Further, the angle between △A and O, or the angle between △B and O can be calculated according to the sine function or cosine function, so as to obtain the wind direction.

[0047] Please combine Figure 3 In other embodiments, optionally, the wind speed and wind direction detection device further includes a base 500 and a driver 600, wherein the base 500 is used to be fixed on the ground surface, and the driver 600 is installed on the base 500. The driver 600 is connected to the supporting shell 100 and is used to drive the supporting shell 100 to rotate around a preset axis, wherein the preset axis extends vertically in the working state. The number of the second atmospheric pressure sensor 400 is one and is installed on the side of the supporting shell 100. In the process of detecting the wind speed, the driver 600 can drive the supporting shell 100 to rotate, thereby driving the second atmospheric pressure sensor 400 to rotate around the preset axis extending vertically through the supporting shell 100, so that the second atmospheric pressure sensor 400 can obtain multiple environmental values ​​of wind speeds in a week. It should be understood that when the second atmospheric pressure sensor 400 rotates to face the wind direction, the value obtained by the second atmospheric pressure sensor 400 is the required environmental value, that is, the environmental values ​​obtained by rotating the second atmospheric pressure sensor 400 one circle are compared, and the largest environmental value is selected. The largest environmental value is the wind pressure obtained by the second atmospheric pressure sensor 400 when the second atmospheric pressure sensor 400 is facing the wind direction. The maximum environmental value is subtracted from the reference value of the detection activity of the first atmospheric pressure sensor 300 to obtain the wind speed. The detection is convenient and accurate.

[0048] Furthermore, in a windless environment, the reference value obtained by the first atmospheric pressure sensor 300 is equal to the environmental value obtained by the second atmospheric pressure. At this time, the driver 600 does not need to work, that is, the driver 600 does not need to drive the supporting shell 100 to rotate, thereby saving energy.

[0049] Specifically, the method for measuring wind speed and direction is as follows:

[0050] Compare the reference value detected by the first atmospheric pressure sensor 300 and the environmental value detected by the second atmospheric pressure sensor 400. When the reference value is equal to the environmental value, the driver 600 stops working, that is, there is no wind in the environment at this time, and the driver 600 does not work, saving energy. When the reference value is not equal to the environmental value, the driver 600 starts and drives the bearing shell 100 to rotate one circle, and the processor 200 records and processes multiple environmental values ​​measured by the second atmospheric pressure sensor 400 rotating one circle, selects the highest environmental value among the multiple environmental values, and subtracts the highest environmental value from the reference value, and the obtained numerical difference is the environmental wind speed; and the processor 200 obtains the angle of rotation of the bearing shell 100 during the process of rotating from the initial position to the position with the highest environmental value, and the angle corresponds to the wind direction of the environmental wind speed. It should be understood that the processor 200 can store and compare the values ​​obtained by the atmospheric pressure sensor to control the driver 600, and the processor 200 can be connected to the intelligent terminal for communication, and the data and the analysis results are transmitted to the intelligent terminal, which is conducive to the preservation of data and the display of data.

[0051] It should be understood that in order to improve the measurement accuracy, multiple second atmospheric pressure sensors 400 can be arranged in the circumference of the carrier shell 100. When the environmental value obtained by one of the second atmospheric pressure sensors 400 increases, it can be known that wind has been generated in the environment. Therefore, under the control of the processor 200, the driver 600 is started, which can drive multiple second atmospheric pressure sensors 400 to rotate at the same time, so as to obtain the environmental wind speed more timely and effectively. Multiple second atmospheric pressure sensors 400 rotate one circle, and each second atmospheric pressure sensor 400 can obtain multiple environmental values. The largest environmental value among the multiple environmental values ​​obtained by each second pressure sensor is taken out, and then the average of the multiple largest environmental values ​​is calculated, and the average is subtracted from the reference value to obtain the wind speed, reduce the error, and improve the accuracy of the measurement result.

[0052] In addition, in order to facilitate the connection between the rotating shaft of the driver 600 and the supporting shell 100, a plurality of connecting rods 130 are installed on the open side of the enclosure 120, and a connecting ring 140 is installed in the middle of the plurality of connecting rods 130. The rotating shaft is connected and fixed to the connecting ring 140, and there is a gap between adjacent connecting rods 130 to communicate with the outside world. In this way, it will not affect the first atmospheric pressure sensor 300 in the enclosure 120 to measure the atmospheric pressure of the external environment.

[0053] Optionally, the wind speed and direction detection device further includes an angle sensor or a gyroscope, which is mounted on the carrier shell 100 and is used to obtain the rotation angle of the rotating shaft. The angle sensor or the gyroscope can be used to obtain the angle that the second atmospheric pressure sensor 400 rotates from the initial position to the maximum environmental value, that is, the wind direction can be known, and the detection is convenient and quick.

[0054] Optionally, the bearing shell 100 includes a main shell 110 and a baffle 120 installed at the bottom of the main shell 110, and the side of the baffle 120 facing away from the main shell 110 is set to be open, and the opening is used to connect to the external environment; the baffle 120 cooperates with the main shell 110 to define a windproof cavity 101, and the first atmospheric pressure sensor 300 is installed on the main shell 110. The structure of the bearing shell 100 is simple, and the windproof cavity 101 is arranged at the bottom of the bearing shell 100. The airflow in the windproof cavity 101 is less affected by the external environment, which can improve the accuracy of the wind speed measurement result.

[0055] Please combine Figure 4 In other embodiments, the wind speed and direction detection device may further include an electronic compass 700 or a magnetic sensor that is connected to the processor 200. The electronic compass 700 or the magnetic sensor is mounted on the carrier shell 100. The electronic compass 700 or the magnetic sensor is used to obtain direction data; the direction data is combined with the rotation angle obtained by the angle sensor to obtain the wind direction, that is, the direction data and the rotation angle data are combined to obtain the wind direction through a calculation formula. The calculation formula is a well-known formula, and in order to avoid repeated description, it is not described in detail in this embodiment.

[0056] In other embodiments, optionally, the wind speed and direction detection device further includes a temperature and humidity sensor 800 that is communicatively connected to the processor 200, the temperature and humidity sensor 800 is connected to the carrier shell 100, and the temperature and humidity sensor 800 is used to obtain the ambient temperature and humidity.

[0057] The wind speed and direction detection device provided in this embodiment has high accuracy in obtaining wind speed and direction, long service life and low operating cost.

[0058] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
