[0031] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this 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.

[0032] It should be noted that, in the embodiment of the present invention, the anemometer 100 of this embodiment can reflect the changes in the wind field by setting up a heating element and multiple temperature measuring elements to establish a temperature field. Since the heating element and the temperature measuring element are both relatively sophisticated thermal elements, the anemometer 100 of this embodiment has a simple structure and a smaller size compared to the wind speed and direction measuring device in the prior art, thereby reducing production costs and maintenance costs.

[0033] like Figure 1 As shown, an embodiment of the present invention provides a weather station comprising a mounting bracket 60 , a housing 80 disposed on the mounting bracket 60 , a rain gauge 70 disposed in the housing 80 , and the aforementioned wind gauge 100 connected to the housing 80 .

[0034] Through the above settings, the weather station can not only detect wind speed and direction, but also precipitation, thereby increasing the functionality of the weather station.

[0035] 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 .

[0036] Preferably, in an embodiment of the present invention, the housing 80 includes an upper shell and a lower shell connected to the upper shell, the anemometer 100 is disposed in the upper shell, and the rain gauge 70 is disposed in the upper shell.

[0037] like Figures 2 to 5 As shown, in this embodiment of the present invention, the weather station further includes a mounting member 13. The housing 80 has a mounting slot 81. The mounting member 13 includes a mounting body 131 and a sleeve 132. At least a portion of the mounting body 131 is located within the mounting slot 81 and is connected to the housing 80. The sleeve 132 is connected to the mounting body 131, with at least a portion of the sleeve 132 located within the mounting cavity 101. The end of the sleeve 132, which is away from the mounting body 131, abuts against the second circuit board 21 of the control assembly 20.

[0038] Through the above-mentioned setting, the anemometer 100 can be installed on the housing 80 through the mounting member 13, and the sleeve 132 can press the second circuit board 21 onto the fixing member 110, so that the second temperature measuring member 34, the first temperature measuring member 33 and the heating member 32 on the first circuit board 31 can better contact the bottom wall 12.

[0039] The present invention and its embodiments provide a novel anemometer 100, as described below:

[0040] like Figure 6 and Figure 8 As shown, an embodiment of the present invention provides a wind detector 100 , which includes a mounting housing 10 , a control component 20 , and a detection component 30 . Among them, the mounting shell 10 includes a bottom wall 12, a circumferential side wall 11 connected to the bottom wall 12, and an installation cavity 101 surrounded by the bottom wall 12 and the circumferential side wall 11; the control component 20 includes a controller 90; the detection component 30 is located in the installation cavity 101, and the detection component 30 includes a first circuit board 31, multiple first temperature measuring components 33, a second temperature measuring component 34 and a heating component 32 for heating the bottom wall, the first temperature measuring component 33 and the second temperature measuring component 34 are both arranged on the side of the first circuit board 31 facing the bottom wall 12, and the first temperature measuring component 33 and the second temperature measuring component 34 are configured to be able to contact the bottom wall 12, wherein the second temperature measuring component 34 is located in the middle position of the first circuit board 31, and multiple first temperature measuring components 33 are arranged at intervals around the second temperature measuring component 34, and the first circuit board 31 and the controller 90 are electrically connected to transmit the signals detected by the first temperature measuring component 33 and the second temperature measuring component 34 to the controller 90.

[0041] In the above technical solution, the bottom wall 12 of the mounting shell 10 is heated by setting a heating element 32, a second temperature measuring element 34 is set in the middle position of the bottom wall 12, and multiple first temperature measuring elements 33 are set around the bottom wall 12. In this way, the temperatures of multiple positions of the bottom wall 12 can be measured, so that a temperature field can be established on the bottom wall 12. When the windward side of the bottom wall 12 (the side of the bottom wall 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. According to the principle of convective heat transfer, the temperature of each position on the temperature field plane will also change according to the flow of wind. Then, multiple first temperature measuring elements 33 and second temperature measuring elements 34 can be used to measure the temperature changes at different positions of the bottom wall 12, so that the wind speed can be measured according to the temperature changes. The above-mentioned anemometer 100 can effectively improve the accuracy of wind speed measurement by setting multiple first temperature measuring components 33 and second temperature measuring components 34 to measure the change of temperature field, thereby making it easier for farmers to obtain farmland environmental conditions.

[0042] Specifically, in an embodiment of the present invention, two first temperature measuring members 33 disposed opposite to each other and a second temperature measuring member 34 located between the two first temperature measuring members 33 can measure the temperature at three locations on the bottom wall 12. In this way, when the windward surface of the bottom wall 12 senses the wind, the temperature at the three locations 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 senses the wind, any two first temperature measuring members 33 disposed opposite to each other among the plurality of first temperature measuring members 33 and the second temperature measuring member 34 located between the two first temperature measuring members 33 can generate a temperature gradient. In this way, using the generated multiple temperature gradients to calculate the wind speed can effectively improve the accuracy of the wind speed measurement.

[0043] 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.

[0044] 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.

[0045] Preferably, in an embodiment of the present invention, the anemometer 100 further includes 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.

[0046] 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.

[0047] Preferably, in an embodiment of the present invention, the anemometer 100 further includes an insulating layer provided 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 , thereby ensuring that the bottom wall 12 has good electrical insulation.

[0048] Preferably, in the embodiment of the present invention, the number of the first temperature measuring elements 33 is eight. Of course, in alternative embodiments not shown in the drawings, the number of the first temperature measuring elements 33 may also be six or ten, etc.

[0049] Preferably, in the embodiment of the present invention, the first circuit board 31 may be a circular circuit board so as to be easily installed in the mounting housing 10 .

[0050] It should be noted that, in the embodiment of the present invention, the middle position includes the position of the center line of the first circuit board 31 and the position deviated from the center line by a preset distance. Preferably, the second temperature measuring element 34 is located at the center of the first circuit board 31.

[0051] Preferably, in an embodiment of the present invention, the controller 90 can calculate the wind speed through the temperature changes measured by the first temperature measuring component 33 and the second temperature measuring component 34, and the controller 90 is connected to the display device to display the wind speed on the display screen of the display device.

[0052] Preferably, if Figure 2 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 .

[0053] Specifically, in an embodiment of the present invention, the first temperature measuring element 33 and the second temperature measuring element 34 are configured as temperature sensors, preferably thermistor temperature sensors. In this way, the thermal sensing principle can be utilized to construct a two-dimensional thermal field plane reflected by the potential through the thermal sensing element.

[0054] like Figure 8 As shown, in the embodiment of the present invention, a plurality of first temperature measuring elements 33 are evenly spaced around the second temperature measuring element 34 , and the heating element 32 is located between the second temperature measuring element 34 and at least one first temperature measuring element 33 .

[0055] In the above technical solution, multiple first temperature measuring elements 33 are evenly spaced around the second temperature measuring element 34. In this way, 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 first temperature measuring element 33 can measure the temperature change, thereby more accurately measuring the direction of the wind.

[0056] Specifically, in an embodiment of the present invention, the number of first temperature measuring elements 33 is eight, and the eight first temperature measuring elements 33 are evenly spaced around the second temperature measuring element 34. In this way, four electrical coordinate axes with a 45-degree scale can be established on the two-dimensional temperature field plane, and the heat source is located on the inner side of the multiple first 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 elements also presents a symmetrical distribution. 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 the wind, so that the direction of the wind flow can be measured based on this change.

[0057] Specifically, in an embodiment of the present invention, the heating element 32 is arranged between the second temperature measuring element 34 and at least one first temperature measuring element 33. In this way, the positions of the bottom wall 12 where the second temperature measuring element 34 and the first temperature measuring element 33 are provided can be heated, thereby making subsequent measurement results more accurate.

[0058] like Figure 8 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 second temperature measuring element 34 .

[0059] By the above arrangement, the bottom wall 12 can be heated more evenly, thereby facilitating the establishment of a uniformly arranged temperature field. Preferably, the heating element 32 is in the shape of a rectangular plate.

[0060] Of course, in alternative embodiments not shown in the drawings, the number of heating elements 32 may also be three, four, five, or the like.

[0061] Alternatively, in an alternative embodiment not shown in the drawings, the heating element 32 may also be annular and located at the periphery of the second temperature measuring element 34 , so that the bottom wall 12 can be heated evenly.

[0062] like Figure 6 and Figure 7 As shown, in an embodiment of the present invention, the control component 20 also includes a second circuit board 21 electrically connected to the first circuit board 31, the first circuit board 31 is electrically connected to the controller 90 through the second circuit board 21, the second circuit board 21 is located in the installation cavity 101, and the detection component 30 is movably arranged along the first direction relative to the second circuit board 21.

[0063] Through the above-mentioned arrangement, before the detection component 30 and the partial control component 20 are installed, the detection component 30 can be moved upward along the first direction relative to the second circuit board 21, and then the second circuit board 21 and the detection component 30 can be fixed in the installation cavity 101. In this way, under the action of external force, the detection component 30 will move downward along the first direction relative to the second circuit board 21, so that the second temperature measuring component 34, the first temperature measuring component 33 and the heating component 32 can be in contact with the bottom wall 12. In this way, the problem of the second temperature measuring component 34, the first temperature measuring component 33 and the heating component 32 being unable to contact the bottom wall 12 due to manufacturing accuracy problems can be avoided, thereby improving the accuracy of temperature detection, and then improving the accuracy of wind speed measurement.

[0064] Furthermore, by providing the second circuit board 21 , the detection component 30 can be fixed in the installation cavity 101 , and the first circuit board 31 can be controlled and connected to the controller 90 through the second circuit board 21 .

[0065] It should be noted that, in the embodiment of the present invention, the external force may be gravity or elastic force, as long as the second temperature measuring element 34 , the first temperature measuring element 33 and the heating element 32 can be brought into contact with the bottom wall 12 .

[0066] It should be noted that, in the embodiment of the present invention, the first direction is the direction of the axis of the mounting housing 10 .

[0067] like Figure 6 and Figure 7 As shown, in the embodiment of the present invention, the anemometer 100 further includes an elastic member 50 located between the first circuit board 31 and the second circuit board 21 , one end of the elastic member 50 is electrically connected to the first circuit board 31 , and the other end of the elastic member 50 is electrically connected to the second circuit board 21 .

[0068] Through the above-mentioned arrangement, before the detection component 30 and the partial control component 20 are installed, the detection component 30 can be moved upward along the first direction relative to the second circuit board 21, that is, the elastic member 50 is compressed, and then the second circuit board 21 and the detection component 30 are fixed in the installation cavity 101. In this way, under the action of the restoring force of the elastic member, the detection component 30 can be moved downward along the first direction relative to the second circuit board 21, so that the second temperature measuring component 34, the first temperature measuring component 33 and the heating component 32 can be in contact with the bottom wall 12. In this way, the problem of the second temperature measuring component 34, the first temperature measuring component 33 and the heating component 32 being unable to contact the bottom wall 12 due to manufacturing accuracy problems can be avoided, thereby improving the accuracy of temperature detection, and then improving the accuracy of wind speed measurement.

[0069] Furthermore, the elastic member 50 can also realize the electrical connection between the first circuit board 31 and the second circuit board 21 .

[0070] Preferably, in the embodiment of the present invention, the elastic member 50 may be a conductive spring or a POGO PIN (ie, a pogo pin).

[0071] like Figure 7 As shown, in the embodiment of the present invention, the anemometer 100 includes a plurality of elastic members 50 , and at least some of the plurality of elastic members 50 are evenly spaced along the circumference of the first circuit board 31 .

[0072] Through the above-mentioned arrangement, the multiple first 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 first 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.

[0073] Specifically, if Figure 7 As shown, in an embodiment of the present invention, at least part of the multiple first temperature measuring elements 33 are evenly spaced 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. On 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, thereby more accurately measuring the direction of the wind.

[0074] like Figure 7 As shown, in the embodiment of the present invention, the elastic member 50 and the first temperature measuring member 33 are staggered in the horizontal plane, so that the elastic member 50 is provided between two adjacent first temperature measuring members 33 .

[0075] In the above technical solution, an elastic member 50 is provided between two adjacent first temperature measuring elements 33. This ensures that each of the multiple first temperature measuring elements 33 distributed circumferentially along the first circuit board 31 is in contact with the bottom wall 12, allowing each first temperature measuring element 33 to accurately measure the temperature of the bottom wall 12. This improves the accuracy of temperature measurement by the detection assembly 30, and further improves the accuracy of wind speed and direction measurements by the anemometer 100. Furthermore, by staggering the elastic member 50 and the first temperature measuring elements 33 in the horizontal plane, it is possible to prevent heat generated by the elastic member 50 from affecting the detection accuracy of the first temperature measuring elements 33.

[0076] In an alternative embodiment not shown in the accompanying drawings, the elastic member 50 and the first temperature measuring member 33 are arranged correspondingly in the first direction, that is, the positive projections of the first temperature measuring member 33 and the elastic member 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.

[0077] like Figure 6 and Figure 7 As shown, in this embodiment of the present invention, the second circuit board 21 is provided with a guide hole 211. The wind detector 100 further includes a guide structure 40, which includes a main body 41 and a guide member 42. The main body 41 is connected to the first circuit board 31; the guide member 42 is connected to the main body 41. A portion of the guide member 42 is disposed within the guide hole 211, and the guide member 42 and the guide hole 211 are slidably engaged.

[0078] 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.

[0079] like Figure 7 and Figure 9 As 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 .

[0080] Through the above-mentioned arrangement, when the first circuit board 31 moves along the first direction toward the second circuit board 21, the limit member 43 can limit the extreme position of the movement of the first circuit board 31, thereby preventing the second temperature measuring member 34, the first temperature measuring member 33 and the heating member 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 elastic member 50 from being over-compressed and failing.

[0081] Specifically, in the embodiment of the present invention, the limiting member 43 is connected to the main body 41. Of course, in an alternative embodiment not shown in the drawings, the limiting member 43 can also be connected to the guide member 42, as long as the limit position of the movement of the first circuit board 31 can be limited.

[0082] 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.

[0083] like Figure 8 and Figure 9 As shown, in an embodiment of the present invention, the anemometer 100 further includes a snap-fit ​​structure, which includes a slot 35 provided on the first circuit board 31 and a block 44 located on a side of the main body 41 facing the first circuit board 31 , and the block 44 is snap-fitted with the slot 35 .

[0084] Through the above-mentioned setting, 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 maintenance of the first circuit board 31 by technicians.

[0085] Of course, in an alternative embodiment not shown in the accompanying drawings, the snap-fit ​​structure may also include a snap-fit ​​block 44 provided 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 .

[0086] like Figure 6 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 of the control assembly 20 . The fixing member 110 is located in the installation cavity 101 and connected to the circumferential side wall 11 .

[0087] Preferably, in the embodiment of the present invention, the fixing member 110 is a step connected to the circumferential side wall 11. In this way, under the action of an external force, the second circuit board 21 can abut against the step surface, that is, the second circuit board 21 is fixed to 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 circumference, as long as it can support the second circuit board 21.

[0088] From the above description, it can be seen that the above embodiment of the present invention achieves the following technical effects: by setting a heating element to heat the bottom wall of the mounting shell, setting a second temperature measuring element in the middle position of the bottom wall and setting multiple first temperature measuring elements in the circumference of the bottom wall, the temperature of multiple positions of the bottom wall can be measured, so that a temperature field can be established on the bottom wall. When the windward side of the bottom wall (the side of the bottom wall facing away from the detection component) is in a windless state, the wind field is stable, and the temperature field constructed by the anemometer is also stable; when there is wind, the wind field will change. 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. Then, multiple first temperature measuring elements and second temperature measuring elements can be used to measure the temperature changes at different positions of the bottom wall, so that the wind speed can be measured according to the temperature changes. The above anemometer can effectively improve the accuracy of wind speed measurement by setting multiple first temperature measuring elements and second temperature measuring elements to measure the changes in the temperature field.

[0089] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
