Description

Technical Field

[0001] The present invention relates to the technical field of LoRa gateways, and in particular to a LoRa temperature and humidity sensor gateway with good protection effect. Background Art

[0002] The LoRa temperature and humidity sensor gateway combines LoRaWAN technology and temperature and humidity sensor technology. LoRaWAN technology: LoRaWAN (Long Range Wide Area Network) is a low-power wide-area network technology for long-distance, low-power Internet of Things connections. It is based on LoRa (Long Range) modulation technology and can provide long-distance communication capabilities in indoor and outdoor environments. LoRaWAN adopts a star topology, where Internet of Things devices are connected to the Internet through LoRaWAN gateways. The LoRaWAN network supports large-scale device connections and has the characteristics of low power consumption, long signal coverage, and cooperative communication. Temperature and humidity sensor technology: Temperature and humidity sensors are used to measure the temperature and humidity of the surrounding environment. They collect the physical parameters of the environment and convert them into electrical signals for processing and transmission. Temperature and humidity sensors usually use principles such as thermoelectric, capacitive, resistive, or semiconductor to sense changes in temperature and humidity, and there are mainly two types of sensors, digital and analog, and appropriate sensors can be selected according to different application scenarios. The LoRa temperature and humidity sensor gateway combines LoRaWAN technology and temperature and humidity sensor technology, and transmits sensor data to the cloud platform or data center through the LoRaWAN wireless communication protocol. The sensor gateway collects the temperature and humidity data of the sensor nodes and uses the LoRaWAN protocol for data communication, and finally transmits the data to the cloud for storage, analysis, and application.

[0034] Many specific details are set forth in the following description in order to fully understand the present invention, but the present invention can also be implemented in other ways different from those described herein. Those skilled in the art can make similar promotions without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0035] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure or characteristic that can be included in at least one implementation manner of the present invention. The "in one embodiment" appearing in different places in this specification does not all refer to the same embodiment, nor is it a separate or selectively exclusive embodiment from other embodiments.

[0036] Embodiment 1

[0037] Refer to Figures 1 to 6 , which is the first embodiment of the present invention. This embodiment provides a LoRa temperature and humidity sensor gateway with good protection effect, including a bottom shell 1. A top shell 4 is fixedly installed at the top of the bottom shell 1. A positioning and stabilizing component 3 is fixedly installed inside the top shell 4. A circuit board 5 is fixedly installed at the bottom inside the top shell 4. A temperature and humidity sensor module is installed on the circuit board 5, which can detect temperature and humidity and upload data to the server. An adjustment and protection component 2 is fixedly installed outside the bottom shell 1. The adjustment and protection component 2 includes a fixed plate 201, a connecting block 202, a tightening bolt 203, a fixed rod 204, a limiting frame 205, a limiting rod 206, a spring damper 207, a slide block 208, a transmission rod 209, a filter screen 210, a fixed frame 211, a deflector 212 and a drying packet 213;

[0038] On one side of the two fixing plates 201, they are respectively fixedly connected to the bottoms of both sides of the bottom case 1. The inner sides of the fixing plates 201 are slidably connected to the outer sides of the connecting blocks 202. The outer sides of several fastening bolts 203 are respectively slidably connected to the connecting blocks 202 and the inner side of the bottom case 1. The outer sides of the fastening bolts 203 are threadedly connected to the inner side of an external object, and can fix the position of the bottom case 1. The outer sides of the four fixing rods 204 are respectively fixedly connected to the four corners of the inner bottom of the bottom case 1. The tops of the eight limiting frames 205 are symmetrically and fixedly connected to the four corners of the inner top of the top case 4. The inner sides of the two limiting frames 205 are slidably connected to the outer side of the limiting rod 206. One end of each of the four spring dampers 207 is fixedly connected to the inner sides of the two sides of the fixing rod 204 and the limiting rod 206;

[0039] One end of the spring damper 207 is fixedly connected to one side of the slider 208. The slider 208 is slidably connected to the inner sides of the fixing rod 204 and the limiting rod 206, and can limit the moving direction of the slider 208. One side of each of the two sliders 208 is rotatably connected to both ends of the transmission rod 209. The outer sides of the two filter meshes 210 are respectively fixedly connected to the middle parts of both sides of the top case 4, and can filter impurities in the gas entering the top case 4. One side of each of the two fixing frames 211 is fixedly connected to both sides of the inner side of the top case 4. The bottoms of several flow guide plates 212 are fixedly connected to the inner side edges of the fixing frames 211. The inner side of one fixing frame 211 is slidably connected to the outer side of the drying packet 213. The drying packet 213 is located at one side of the flow guide plates 212, and can adsorb moisture in the entering gas;

[0040] The staff moves the connecting block 202, and the connecting block 202 is slidably connected to the inner side of the fixing plate 201 by the connecting block 202, so that the moving direction of the connecting block 202 can be limited. When the connecting block 202 is moved to the appropriate position, the staff moves the fastening bolt 203, so that the fastening bolt 203 passes through the bottom shell 1 and the inner side of the connecting block 202, and twists the fastening bolt 203. The outer side of the fastening bolt 203 is threadedly connected with the external object, so that the position of the moving connecting block 202 can be fixed, thereby completing the installation of the bottom shell 1. Afterwards, the staff moves the top shell 4. During the movement of the top shell 4, the limiting rod 206 is slidably connected to the inner side of the limiting frame 205 fixedly installed on the inner side of the top shell 4, so that the moving direction of the top shell 4 can be limited. When the top shell 4 is moved to the appropriate position, the top shell 4 can be fixedly connected to the bottom shell 1 by the bolts. Afterwards, when external gas enters the inner side of the top shell 4, the impurities in the gas can be filtered out by the filter 210 fixedly installed inside the top shell 4. The gas is filtered and then guided by the guide plate 212. The guided gas flows into the inner side of the drying bag 213. The moisture in the gas can be adsorbed by the drying bag 213. The dried gas flows into the inner side of the top shell 4, and the inner side of the top shell 4 can be heat-dissipated. At the same time, during the use of the top shell 4, if the top shell 4 is hit by an external object, the position of the limit rod 206 connected to the inner side of the top shell 4 will move. During the movement of the limit rod 206, the slider 208 is respectively slidably connected to the fixed rod 204 and the inner side of the limit rod 206, and the two sliders 208 are connected by a transmission rod 209, so that the limit rod 206 moves and drives the slider 208 to move. During the movement of the slider 208, the spring damper 207 fixedly installed on one side of the slider 208 can buffer the impact force on the top shell 4, thereby improving the structural strength of the gateway.

[0041] Example 2

[0042] Reference Figures 6 to 8 , which is the second embodiment of the present invention. This embodiment is based on the previous embodiment. The positioning and stabilizing component 3 includes a fixing frame 301, a bidirectional screw rod 302, a slide seat 303, a threaded cylinder 304, a threaded column 305, a limiting column 306, a pressing plate 307 and a rubber pad 308;

[0043] The top of the inner side of the top shell 4 is fixedly connected to the top end of the fixing frame 301. The inner side of the fixing frame 301 is rotatably connected to the outer side of the bidirectional lead screw 302. The inner sides of the two sliding seats 303 are respectively threadedly connected to the outer sides of the two side parts of the bidirectional lead screw 302. The sliding seats 303 are slidably connected to the inner side of the fixing frame 301, which can limit the moving direction of the sliding seats 303. The middle part of the bottom end of the sliding seat 303 is rotatably connected to the top end of the threaded barrel 304. The inner side of the threaded barrel 304 is rotatably connected to the outer side of the threaded column 305. The middle part of the bottom end of the sliding seat 303 is fixedly connected to the top end of the limiting column 306. The outer side of the limiting column 306 is threadedly connected to the inner side of the threaded column 305, which can prevent the threaded column 305 from rotating when moving. The bottom end of the threaded column 305 is fixedly connected to the top end of the pressing plate 307. The bottom end of the pressing plate 307 is fixedly connected to the top end of the rubber pad 308. The bottom end of the rubber pad 308 is in contact with the circuit board 5, which can stably process the installed circuit board 5 and ensure the stability of the circuit board 5 during use.

[0044] When the staff needs to install the top shell 4, the staff twists the bidirectional lead screw 302. Through the threaded connection between the outer side of the bidirectional lead screw 302 and the inner side of the sliding seat 303, the two sliding seats 303 can be moved relatively synchronously, and then the position of the threaded barrel 304 connected to the bottom end of the sliding seat 303 can be adjusted and fixed. When the threaded barrel 304 moves to the appropriate position, the staff rotates the threaded barrel 304. Through the threaded connection between the inner side of the threaded barrel 304 and the outer side of the threaded column 305, the position of the threaded column 305 can be moved. During the movement of the threaded column 305, through the sliding connection between the inner side of the threaded column 305 and the outer side of the limiting column 306, the threaded column 305 can be prevented from rotating when moving, and then the position of the pressing plate 307 fixedly connected to the bottom end of the threaded column 305 can be adjusted and fixed. When the installation of the top shell 4 is completed, the extrusion of the circuit board 5 by the rubber pad 308 fixedly connected to the bottom end of the pressing plate 307 can ensure the stability of the circuit board 5 during use.
