[0023] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0024] It should be noted that, although the functional modules are divided in the device schematic diagram and the logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than the module division in the device or the order in the flowchart. The terms "first", "target" and the like in the specification, claims or the above drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0025] Reference Figures 1 to 3 The rain and snow sensor provided in this embodiment includes:

[0026] The housing comprises an upper housing 30 and a lower housing 70, wherein the lower housing 70 is fixed to the lower side of the upper housing 30, a top cover 20 is disposed on the upper side of the upper housing 30, and a first boss 10 extending upward is disposed on the upper side of the top cover 20;

[0027] The rain and snow detection device 80 is disposed inside the housing and is used to detect rain and snow signals. The detection end of the rain and snow detection device 80 is aligned with the first boss 10 .

[0028] It should be noted that the shape of the first boss 10 is not limited, as long as the first boss 10 is higher than the top cover 20, and there is a height difference between the first boss 10 and the upper shell 30. The rain and snow sensor is installed in an outdoor environment. When it rains or snows in the outdoor environment, rain or snow falls on the top cover 20. The first boss 10 higher than the upper shell 30 can make the rain or snow gathered on the first boss 10 flow from the first boss 10 to the upper shell 30, and the rain or snow on the first boss 10 can be drained away in time, thereby improving the detection accuracy of the rain and snow sensor.

[0029] It should be noted that the detection end of the rain and snow detection device 80 is aligned with the first boss 10. When rain or snow falls on the first boss 10, the rain and snow detection device 80 can obtain a rain and snow signal through the first boss 10, thereby obtaining the outdoor rain or snow environment.

[0030] It should be noted that the rain and snow sensor is installed in an outdoor environment. When the outdoor environment is rainy or snowy, rain or snow falls on the first boss 10. The detection end of the rain and snow detection device 80 obtains a rain and snow signal through the first boss 10, and processes the obtained rain and snow signal to obtain real-time outdoor rainfall or snow conditions. The rain or snow falling on the first boss 10 flows from the first boss 10 to the top cover 20, thereby timely draining the rain or snow from the first boss 10, ensuring that the rain and snow signal obtained by the detection end of the rain and snow detection device 80 is accurate.

[0031] In addition, in one embodiment, referring to Figure 2 and Figure 3 A first through hole is provided on the upper side of the upper shell 30, the top cover 20 is installed in the first through hole, the lower shell 70 is sealed and connected to the upper shell 30, and a closed cavity is formed between the upper side of the lower shell 70 and the lower side of the upper shell 30.

[0032] It should be noted that the top cover 20 can be installed on the first through hole by means of screws or other connecting parts, and the first through hole facilitates the transmission of the rain and snow signal of the first boss 10 to the rain and snow detection device 80 located inside the shell.

[0033] It should be noted that the lower shell 70 is sealed and connected to the upper shell 30, so that in the subsequent installation process, other components of the rain and snow sensor can be installed in the closed cavity at any time, and the air inside the closed cavity can be isolated from the air outside the closed cavity, so that the rain and snow detection device 80 located inside the shell is in a stable physical environment.

[0034] In addition, in one embodiment, referring to Figure 3 , also includes a humidity sensor and a first sealing ring 40, the humidity sensor is installed inside the closed cavity, the humidity sensor is used to measure the air humidity outside the closed cavity, the humidity sensor includes a humidity detection chip 50, the humidity detection chip 50 is arranged downward, a second through hole 72 is arranged on the lower side of the lower shell 70, the humidity detection chip 50 covers the upper side of the second through hole 72, and the first sealing ring 40 is sealed between the humidity detection chip 50 and the second through hole 72.

[0035] It should be noted that the surface of the humidity detection chip 50 contacts the air outside the closed cavity, thereby obtaining the external air humidity of the closed cavity. The first sealing ring 40 is used to ensure the airtightness of the closed cavity and prevent the air outside the closed cavity from entering the closed cavity and affecting the detection accuracy of the humidity detection chip 50.

[0036] It should be noted that, in order to ensure accurate air humidity measurement results, the second through hole 72 is provided on the lower side of the lower housing 70, and the humidity detection chip 50 is provided downwardly, so that when the rain and snow sensor is located outdoors, rain is prevented from entering the second through hole 72 and affecting the detection effect of the humidity detection chip 50. The second through hole 72 located on the lower side of the lower housing 70 can also prevent dew generated by the temperature difference between morning and evening in the outdoor environment from gathering in the second through hole 72 and affecting the accuracy of the detection result of the humidity detection chip 50.

[0037] In addition, in one embodiment, referring to Figure 3 A second boss 31 is disposed on the lower edge of the upper shell 30 , and a groove 71 is disposed on the upper edge of the lower shell 70 . The second boss 31 is located inside the groove 71 .

[0038] It should be noted that the upper shell 30 is buckled with the lower shell 70, and the second boss 31 of the upper shell 30 is located inside the groove 71 of the lower shell 70, so as to realize the connection between the upper shell 30 and the lower shell 70. The second boss 31 and the groove 71 facilitate the buckling and positioning of the upper shell 30 and the lower shell 70, improve the installation efficiency between the upper shell 30 and the lower shell 70, and make it difficult for external air to pass through the second boss 31 and the groove 71, so as to improve the sealing effect between the upper shell 30 and the lower shell 70.

[0039] In addition, in one embodiment, referring to Figure 2 and Figure 3 , and also includes a second sealing ring 60 , which is located inside the groove 71 , and the second sealing ring 60 is sealed to the groove 71 and the second boss 31 .

[0040] It should be noted that the second sealing ring 60 is arranged inside the groove 71 to ensure the airtightness of the closed cavity. In the specific implementation process, since the rain and snow sensor is located in an outdoor environment, the closed cavity will be affected by a certain temperature, and the external temperature influence will cause the internal and external air pressure of the closed cavity to change. The second boss 31 and the groove 71 can prevent the second sealing ring 60 from being squeezed and deformed due to the change in air pressure and shifting.

[0041] In addition, in one embodiment, referring to Figure 1 , the top cover 20 is made of non-metallic material.

[0042] It should be noted that the first boss 10 and the top cover 20 made of non-metallic materials can transmit external rain and snow signals to the rain and snow detection device 80 inside the housing, thereby preventing the metal material from shielding the rain and snow signals.

[0043] It should be noted that the rain and snow sensor is installed in an outdoor environment. When the outdoor environment is raining or snowing, the rain or snow falls on the first boss 10. The detection end of the rain and snow detection device 80 is aligned with the first boss 10. The rain and snow detection device 80 collects and processes the rain and snow signals through the first boss 10, and finally outputs the rain or snow result. The height difference between the first boss 10 and the upper shell 30 enables the rain or snow falling on the first boss 10 to flow to the upper shell 30 in time, ensuring the detection accuracy of the rain and snow sensor. The humidity detection chip 50 contacts the outside air and collects the air humidity signal of the outside air. The humidity sensor processes the collected air humidity signal and finally obtains the air humidity of the outdoor air.

[0044] In addition, an embodiment of the present invention further provides a sensing system, including the above rain and snow sensor.

[0045] It should be noted that the sensing system may be the rain and snow sensor itself, or other equipment using the rain and snow sensor. This embodiment does not limit the specific type of the sensing system, and any system that can use the above-mentioned rain and snow sensor will suffice.

[0046] In addition, in one embodiment, referring to Figure 5 The sensing system includes a monitoring device, a rain and snow sensor is installed on the upper side of the monitoring device, and the sensing system also includes a top cover 200, which is fixedly connected to both sides of the monitoring device, and is located on the upper side of the monitoring device. A gap is left between the top cover 200 and the monitoring device, and the length of the top cover 200 is greater than the length of the monitoring device.

[0047] It should be noted that the monitoring equipment includes but is not limited to cameras, radar bodies, etc. that can be used for outdoor monitoring, and can be equipped with rain and snow sensors, which together serve as components of the sensing system.

[0048] It should be noted that the top cover 200 is fixedly connected to the monitoring device including but not limited to screw connection, snap connection or riveting connection.

[0049] It should be noted that a certain gap is left between the top cover 200 and the monitoring device, which can facilitate air circulation between the top cover 200 and the monitoring device, thereby reducing the temperature of the monitoring device. The top cover 200 is located above the monitoring device and the length of the top cover 200 is greater than the length of the monitoring device, which prevents the monitoring device from being directly exposed to sunlight and can reduce the temperature rise of the monitoring device caused by light.

[0050] In addition, in one embodiment, referring to Figure 4 and Figure 5 A third through hole 210 is provided on the upper side of the top cover 200 , and the first boss 10 extends out of the third through hole 210 .

[0051] It should be noted that the first boss 10 of the rain and snow sensor is installed on the third through hole 210 of the top cover 200, which is higher than the first boss 10 of the top cover 200. This allows rain or snow falling on the first boss 10 to slide down to the top cover 200, preventing rain or snow from gathering on the first boss 10 and affecting the detection accuracy of the rain and snow detection device 80.

[0052] In addition, in one embodiment, referring to Figures 1 to 5 At least two fourth through holes 220 are provided on the upper side of the top cover 200, and the fourth through holes 220 are in a long strip shape.

[0053] It should be noted that at least two of the elongated fourth through holes 220 can be used as handles to facilitate the movement of the sensor system and improve transportation portability.

[0054] It should be noted that the sensing system is installed outdoors. When the outdoor environment is rainy or snowy, the rain or snow falls on the first boss 10 and flows to the top cover 200. The top cover 200 shields part of the rain or snow for the monitoring device. The rain and snow detection device 80 collects and processes the rain and snow signals through the first boss 10, and finally obtains the rain or snow weather conditions of the outdoor environment. The humidity detection chip 50 contacts the outdoor air, obtains the outdoor air humidity signal and transmits it to the humidity sensor. The humidity sensor processes the air humidity signal and finally obtains the air humidity of the outdoor environment. When the outdoor environment is sunny, the top cover 200 shields the monitoring device from direct sunlight, reduces the temperature rise of the monitoring device, and prolongs the service life of the monitoring device. When the position of the sensing system needs to be moved, at least two fourth through holes 220 can be passed through, and the top cover 200 between the fourth through holes 220 can be used as a handle to facilitate the movement of the sensing system.
