[0030] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0031] like Figures 1 to 3As shown, an embodiment of the present invention provides a wind meter. The wind meter 100 includes a mounting shell 10, a detection assembly 30 and a floating mechanism. The mounting shell 10 includes a bottom wall 12, a circumferential side wall 11 connected to the bottom wall 12, and a mounting cavity 101 surrounded by the bottom wall 12 and the circumferential side wall 11; the detection assembly 30 is located in the mounting cavity 101, and the detection assembly 30 includes a first circuit board 31 and a plurality of temperature measuring components 33 arranged on the first circuit board 31; the floating mechanism is located in the mounting cavity 101, and the floating mechanism includes a floating assembly 50 connected to the first circuit board 31, and the floating assembly 50 is used to move the temperature measuring component 33 along a first direction so that the temperature measuring component 33 contacts the bottom wall 12.

[0032] In the above technical solution, by providing a floating component 50 that can move the temperature measuring component 33 along the first direction, multiple temperature measuring components 33 can contact the bottom wall at the same time under the action of the floating component 50. In this way, when multiple temperature measuring components 33 detect the temperature at different positions of the bottom wall, the temperature at different positions of the bottom wall 12 can be transferred to the multiple temperature measuring components 33 through the floating component 50, thereby improving the accuracy of the temperature detection of multiple positions of the bottom wall 12 by the multiple temperature measuring components 33, and further improving the accuracy of the wind direction and wind speed detection by the anemometer 100.

[0033] Specifically, in an embodiment of the present invention, the anemometer 100 also includes a heating element 32 arranged on the first circuit board 31, and the heating element 32 can heat the bottom wall 12 of the mounting shell 10, so that a plurality of temperature measuring elements 33 can measure the temperature of a plurality of positions of the bottom wall 12, so that a temperature field can be established on the bottom wall 12, and when the windward surface of the bottom wall 12 (the side of the bottom wall 12 facing away from the detection component 30) is in a windless state, that is, the wind field is stable, and the temperature field constructed by the anemometer 100 is also stable; when there is wind, the wind field will change, and according to the principle of convective heat transfer, the temperature of each position of the temperature field plane will also change according to the flow of wind, and then a plurality of temperature measuring elements can be used to measure the temperature changes at different positions of the bottom wall 12, so that the wind speed and wind direction can be measured according to the temperature changes, thereby facilitating farmers and other personnel to obtain farmland environmental conditions.

[0034] Specifically, in the embodiment of the present invention, the heating element 32 is located on the side of the first circuit board 31 facing the bottom wall 12 , so that the bottom wall 12 can be heated better.

[0035] Specifically, in the embodiment of the present invention, the heating element 32 is in contact with the bottom wall 12 , so that the bottom wall 12 can be heated better.

[0036] Preferably, in an embodiment of the present invention, the anemometer 100 further comprises a connector connected to the bottom wall 12 , and the bottom wall 12 is connected to the circumferential side wall 11 via the connector, so that the bottom wall 12 and the circumferential side wall 11 can be integrally formed by inlaying.

[0037] Preferably, in an embodiment of the present invention, the circumferential side wall 11 is made of plastic material, which is beneficial to reducing the mass of the anemometer 100; the bottom wall 12 is made of metal material, preferably copper, which can increase the thermal conductivity of the bottom wall 12, so that the temperature measuring component can detect the temperature of the bottom wall 12.

[0038] Preferably, in an embodiment of the present invention, the anemometer 100 further comprises an insulating layer arranged on the leeward side of the bottom wall 12, that is, an insulating layer is provided on the side of the bottom wall 12 facing the detection assembly 30, so that the bottom wall 12 can be ensured to have good electrical insulation.

[0039] Preferably, in the embodiment of the present invention, the number of the temperature measuring elements 33 is nine. Of course, in alternative embodiments not shown in the drawings, the number of the first temperature measuring elements 33 may also be eight or ten, etc.

[0040] Preferably, in the embodiment of the present invention, the first circuit board 31 may be a circular circuit board, so as to be installed in the installation housing 10 .

[0041] Specifically, in an embodiment of the present invention, the anemometer 100 also includes a controller 90 connected to the first circuit board 31, and the temperature measuring component 33 transmits the detected signal to the controller 90, so that the controller 90 can calculate the wind speed and wind direction through the temperature change measured by the temperature measuring component 33, and the controller 90 is connected to the display device to display the wind speed on the display screen of the display device.

[0042] Preferably, if Figure 1 As shown, in the embodiment of the present invention, the controller 90 is located outside the mounting housing 10 . Of course, in an alternative embodiment not shown in the drawings, the controller 90 may be located inside the mounting cavity 101 .

[0043] Specifically, in the embodiment of the present invention, the temperature measuring element 33 is configured as a temperature sensor, preferably a thermistor temperature sensor, so that the thermal sensing principle can be utilized to construct a two-dimensional thermal field plane reflected by the potential through the thermal sensing element.

[0044] like Figure 3As shown, in the embodiment of the present invention, the anemometer 100 also includes a second circuit board 21 arranged in the installation cavity 101, the floating assembly 50 includes a telescopic member 51, the telescopic member 51 has a first end and a second end arranged opposite to each other, the second end is movably arranged along a first direction relative to the first end, one of the first end and the second end of the telescopic member 51 is electrically connected to the first circuit board 31, and the other of the first end and the second end of the telescopic member 51 is electrically connected to the second circuit board 21.

[0045] Through the above-mentioned arrangement, the first circuit board 31 can move along the first direction relative to the second circuit board 21. Under the action of the telescopic member 51, the multiple temperature measuring components 33 on the first circuit board 31 can contact the bottom wall 12, so that the temperatures at different positions of the bottom wall 12 can be transferred to the multiple temperature measuring components 33, thereby improving the accuracy of the temperature detection of multiple positions of the bottom wall 12 by the multiple temperature measuring components 33, thereby improving the accuracy of the wind direction and wind speed detection of the anemometer 100.

[0046] Specifically, Figure 3 As shown, in an embodiment of the present invention, before installing the detection component 30 and the second circuit board 21, the detection component 30 can move upward along a first direction relative to the second circuit board 21, that is, compress the telescopic member 51, and then fix the second circuit board 21 and the detection component 30 in the installation cavity 101. In this way, under the action of the telescopic member 51, the detection component 30 can move downward along the first direction relative to the second circuit board 21, so that multiple temperature measuring components 33 can be in contact with the bottom wall 12. In this way, the problem of the temperature measuring components 33 being difficult to contact with the bottom wall 12 due to manufacturing accuracy problems can be avoided, thereby improving the accuracy of temperature detection, and further improving the accuracy of wind speed and wind direction measurement.

[0047] Furthermore, the telescopic member 51 may also realize electrical connection between the first circuit board 31 and the second circuit board 21 .

[0048] Preferably, in the embodiment of the present invention, the first circuit board 31 is connected to the controller 90 through the second circuit board 21. In this way, sufficient wiring space can be reserved, so as to facilitate the control connection of the first circuit board 31 and the controller 90, thereby facilitating the installation of the detection component 30.

[0049] like Figure 3 and Figure 4 As shown, in the embodiment of the present invention, the floating assembly 50 further includes a connector 52 electrically connected to the second circuit board 21, and the connector 52 is electrically connected to the second end.

[0050] In the above technical solution, the second end of the telescopic member 51 can be better connected to the second circuit board 21 by providing the connecting piece 52, thereby avoiding the situation where the second end is directly connected to the second circuit board 21 and causing poor contact.

[0051] like Figure 3 and Figure 4 As shown, in the embodiment of the present invention, the telescopic member 51 includes a POGO PIN. The POGO PIN (i.e., a spring pin) includes a needle tube, a spring located in the needle tube, and a needle shaft movably arranged relative to the needle tube along the axial direction of the needle tube. Among them, one end of the spring is connected to the needle tube, and the other end of the spring is connected to the needle shaft. The needle tube of the POGO PIN forms the first end, and the needle shaft of the POGO PIN forms the second end.

[0052] Through the above-mentioned arrangement, the needle tube of the POGO PIN is connected to the first circuit board 31, and the needle shaft of the POGO PIN is connected to the second circuit board 21 through the connecting piece 52. In this way, not only can the electrical connection between the first circuit board 31 and the second circuit board 21 be achieved, but the first circuit board 31 can also be moved relative to the second circuit board 21 in a direction away from the second circuit board 21, that is, the multiple temperature measuring components 33 on the first circuit board 31 can abut against the bottom wall 12, so that the temperatures at different positions of the bottom wall 12 can be transmitted to the multiple temperature measuring components 33, thereby improving the accuracy of the temperature detection of multiple positions of the bottom wall 12 by the multiple temperature measuring components 33, which can improve the accuracy of the wind direction and wind speed detection of the anemometer 100.

[0053] Of course, in an alternative embodiment not shown in the drawings, the telescopic member 51 may also be configured as a conductive spring that is telescopically disposed along the first direction.

[0054] like Figure 4 As shown, in the embodiment of the present invention, the wind detector 100 includes a plurality of floating components 50 , and at least part of the plurality of floating components 50 are evenly spaced along the circumference of the first circuit board 31 .

[0055] Through the above arrangement, the multiple temperature measuring components 33 on the first circuit board 31 can be in uniform contact with the bottom wall 12, so that the temperature on the bottom wall 12 is evenly transferred to the multiple temperature measuring components 33. In this way, the accuracy of the detection component 30 in detecting the temperature of the bottom wall 12 can be further improved, thereby improving the accuracy of the wind speed and wind direction detection of the anemometer 100.

[0056] Specifically, Figure 5As shown, in an embodiment of the present invention, at least part of the multiple temperature measuring elements 33 are evenly spaced along the circumference of the first circuit board 31, so that the temperature field constructed by the anemometer 100 is also evenly and symmetrically distributed. On the circumference of the bottom wall 12, no matter which direction the wind flows, the temperature measuring elements 33 can measure the temperature change, thereby more accurately measuring the direction of the wind.

[0057] like Figure 4 As shown, in the embodiment of the present invention, the floating assembly 50 and the temperature measuring element 33 are staggered in the horizontal plane, so that the floating assembly 50 is provided between two adjacent temperature measuring elements 33 .

[0058] In the above technical solution, a floating component 50 is provided between two adjacent temperature measuring components 33, so that each of the multiple temperature measuring components 33 distributed along the circumferential direction of the first circuit board 31 can be in contact with the bottom wall 12, so that each temperature measuring component 33 can accurately measure the temperature of the bottom wall 12, thereby improving the accuracy of the temperature measurement of the detection component 30, and further improving the accuracy of the wind speed and wind direction measurement of the anemometer 100. Further, by staggering the floating component 50 and the temperature measuring component 33 in the horizontal plane, it is possible to avoid the heat generated by the floating component 50 affecting the detection accuracy of the temperature measuring component 33.

[0059] In an alternative embodiment not shown in the accompanying drawings, the floating component 50 and the temperature measuring component 33 are arranged correspondingly in the first direction, that is, the positive projections of the temperature measuring component 33 and the floating component 50 on the first circuit board 31 at least partially overlap, so that a compact structure can be formed, thereby effectively utilizing the limited space between the first circuit board 31 and the second circuit board 21.

[0060] like Figure 4 and Figure 5 As shown, in the embodiment of the present invention, one of the multiple temperature measuring components 33 is located in the middle of the first circuit board 31 , and a floating component 50 is provided on at least one side of the temperature measuring component 33 located in the middle.

[0061] In the above technical solution, a floating component 50 is provided on at least one side of the temperature measuring component 33 located in the middle position, so that the temperature measuring component 33 located in the middle position can contact with the bottom wall 12, so that the temperature measuring component 33 located in the middle position can measure the temperature of the bottom wall 12, so that the detection component 30 can measure the temperature of multiple positions of the bottom wall 12, so as to improve the accuracy of the anemometer 100 in measuring wind speed and wind direction.

[0062] Preferably, in the embodiment of the present invention, floating components 50 are provided on opposite sides of the temperature measuring element 33 located in the middle position, so that the temperature measuring element 33 located in the middle position can be in uniform contact with the bottom wall 12 .

[0063] Preferably, in an embodiment of the present invention, a portion of the multiple floating components 50 are evenly spaced along the circumference of the first circuit board 31, and another portion of the multiple floating components 50 are located on opposite sides of the temperature measuring component 33 at the middle position. In this way, the temperature measuring component 33 at the middle position and the circumferentially distributed temperature measuring components 33 can both contact the bottom wall 12 to improve the accuracy of the anemometer 100 in measuring wind speed and wind direction.

[0064] Of course, in alternative embodiments not shown in the accompanying drawings, the floating component 50 may be arranged only in the circumferential direction, that is, a plurality of floating components 50 are evenly spaced along the circumference of the first circuit board 31, or the floating component 50 is arranged only on the radial inner side of the first circuit board 31, that is, the floating components 50 are provided on the opposite sides of the temperature measuring component 33 located in the middle position.

[0065] Specifically, in an embodiment of the present invention, one of the multiple temperature measuring elements 33 is located in the middle of the first circuit board 31, and the remaining temperature measuring elements 33 of the multiple temperature measuring elements 33 are evenly spaced around the temperature measuring element 33 located in the middle along the circumference of the first circuit board 31. In this way, the temperature field constructed by the anemometer 100 is also evenly and symmetrically distributed. In the circumference of the bottom wall 12, no matter which direction the wind flows, the first temperature measuring element 33 can measure the temperature change, so that the wind direction can be measured more accurately. Furthermore, two of the multiple temperature measuring elements 33 distributed along the circumference and the temperature measuring element 33 located in the middle can measure the temperature of three positions on the bottom wall 12. In this way, when the windward surface of the bottom wall 12 feels the wind, the temperature of the above three positions will change with the flow of the wind, thereby generating a temperature gradient, and then calculating the wind speed. When the windward surface of the bottom wall 12 feels the wind, the three temperature measuring components 33 can generate a temperature gradient. In this way, the wind speed can be calculated by using the generated multiple temperature gradients, which can effectively improve the accuracy of wind speed measurement.

[0066] Preferably, in an embodiment of the present invention, the number of temperature measuring elements 33 is nine, wherein eight temperature measuring elements 33 are evenly spaced around a temperature measuring element 33 located in the middle. In this way, four electrical coordinate axes with a graduation of 45 degrees can be established on the two-dimensional temperature field plane, and the heat source is located on the inner side of multiple temperature measuring elements 33. In this way, in a windless state, the wind field is stable, and the temperature field constructed by the temperature measuring element 33 is also symmetrically distributed. When there is wind, the wind field will change. According to the principle of convective heat transfer, the distribution of the temperature field plane will also shift according to the flow of wind, so that the direction of wind flow can be measured according to this change.

[0067] Specifically, in an embodiment of the present invention, a heating element 32 is provided between the temperature measuring element 33 located in the middle position and a plurality of temperature measuring elements 33 arranged along the circumference of the first circuit board 31, so that the bottom wall 12 can be heated evenly, thereby making subsequent measurement results more accurate.

[0068] It should be noted that, in the embodiment of the present invention, the middle position includes the position where the center line of the first circuit board 31 is located and the position deviating from the center line by a preset distance.

[0069] like Figure 5 As shown, in the embodiment of the present invention, the detection assembly 30 includes two heating elements 32, and the two heating elements 32 are symmetrically arranged relative to the temperature measuring element 33 located in the middle.

[0070] Through the above arrangement, the bottom wall 12 can be heated more evenly, which is conducive to establishing a uniformly arranged temperature field. Preferably, the heating element 32 is in the shape of a rectangular plate.

[0071] Of course, in alternative embodiments not shown in the drawings, the number of the heating elements 32 may also be three, four, five, or the like.

[0072] Alternatively, in an alternative embodiment not shown in the drawings, the heating element 32 may also be annular, and the annular heating element is arranged on the periphery of the temperature measuring element 33 at the middle position, so that the bottom wall 12 can be heated evenly.

[0073] like Figure 6 As shown, in the embodiment of the present invention, a guide through hole 211 is provided on the second circuit board 21, and the wind detector 100 further includes a guide structure 40, and the guide structure 40 includes a body portion 41 and a guide member 42. The guide member 42 is provided on the body portion 41, and a part of the guide member 42 is passed through the guide through hole 211, and the guide member 42 and the guide through hole 211 are slidably matched.

[0074] Through the above arrangement, the guide member 42 is slidably arranged in the guide through hole 211, so that the guide structure 40 can guide the movement of the first circuit board 31 along the first direction, so that the detection component 30 can move more smoothly along the first direction.

[0075] Specifically, in the embodiment of the present invention, a evacuation hole is provided at a position corresponding to the middle position of the main body 41, so that the floating components 50 on opposite sides of the temperature measuring element 33 at the middle position can pass through the evacuation hole. Furthermore, the evacuation hole can also play a role in reducing weight.

[0076] like Figure 4 and Figure 6As shown, in the embodiment of the present invention, the guide structure 40 further includes a limit member 43 located on a side of the main body 41 facing the second circuit board 21 , and the limit member 43 is used to limit the extreme position of movement of the first circuit board 31 .

[0077] Through the above-mentioned arrangement, when the first circuit board 31 moves toward the second circuit board 21 along the first direction, the limit member 43 can limit the extreme position of the movement of the first circuit board 31, thereby preventing multiple temperature measuring components 33 and heating components 32 on the first circuit board 31 from contacting the second circuit board 21 and being damaged; further, by setting the limit member 43, it is also possible to prevent the floating component 50 from being over-compressed and failing.

[0078] Specifically, in the embodiment of the present invention, the limiter 43 is connected to the body 41. Of course, in an alternative embodiment not shown in the drawings, the limiter 43 may be connected to the guide 42 as long as the limit position of the movement of the first circuit board 31 can be limited.

[0079] Preferably, in the embodiment of the present invention, the number of the limiting members 43 is two. Of course, in alternative embodiments not shown in the drawings, the number of the limiting members 43 may also be three or four.

[0080] like Figure 5 and Figure 6 As shown, in an embodiment of the present invention, the anemometer 100 further includes a snap-in structure, which includes a snap-in slot 35 provided on the first circuit board 31 and a snap-in block 44 located on a side of the main body 41 facing the first circuit board 31 , and the snap-in block 44 is snap-fitted with the snap-in slot 35 .

[0081] Through the above arrangement, the snap-fit ​​structure can realize the positioning and detachable connection between the main body 41 and the first circuit board 31, thereby facilitating the removal of the guide structure 40 from the first circuit board 31, and further facilitating the inspection and repair of the first circuit board 31 by technicians.

[0082] Of course, in an alternative embodiment not shown in the drawings, the snap-fit ​​structure may also include a snap-fit ​​block 44 disposed on the side of the first circuit board 31 facing the main body 41 and a snap-fit ​​slot 35 located in the main body 41 , and the snap-fit ​​block 44 is snap-fitted with the snap-fit ​​slot 35 .

[0083] like Figure 3 As shown, in the embodiment of the present invention, the anemometer 100 further includes a fixing member 110 for fixing the second circuit board 21 . The fixing member 110 is located in the mounting cavity 101 , and the fixing member 110 is connected to the circumferential side wall 11 .

[0084] Through the above-mentioned arrangement, the second circuit board 21 can be fixed on the fixing member 110, that is, the second circuit board 21 can be fixed in the mounting cavity 101, so that the second circuit board 21 is fixedly installed, and under the action of the floating component 50, the first circuit board 31 moves along the first direction away from the second circuit board 21, so that the multiple temperature measuring components 33 can be evenly contacted with the bottom wall 12, so as to improve the accuracy of the detection component 30 in detecting wind speed and wind direction.

[0085] Preferably, in the embodiment of the present invention, the fixing member 110 is a step connected to the circumferential side wall 11, so that under the action of external force, the second circuit board 21 can abut against the step surface, that is, the second circuit board 21 is fixed on the step surface. Of course, in an alternative embodiment not shown in the drawings, the fixing member 110 can also be a plurality of ribs arranged at intervals along the circumferential direction, as long as the second circuit board 21 can be supported.

[0086] like Figure 7 As shown, an embodiment of the present invention provides a weather station. The weather station includes a mounting bracket 60, a housing 80 disposed on the mounting bracket 60, a rain gauge 70 disposed in the housing 80, and the above-mentioned anemometer 100 connected to the housing 80. Through the above-mentioned configuration, the weather station can not only detect wind speed and wind direction, but also detect precipitation, thereby increasing the function of the weather station.

[0087] Specifically, in the embodiment of the present invention, the rain gauge 70 is controllably connected to the controller 90 so as to feed back the signal detected by the rain gauge 70 to the controller 90 .
