Description

Technical Field

[0001] The utility model relates to the fields of edge computing, intelligent sensors, environmental perception and long-distance wireless communication, and in particular to an outdoor edge computing intelligent sensor with environmental perception and long-distance wireless communication functions. Background Art

[0002] Edge computing refers to providing edge intelligent services at the edge of the network close to the source of objects or data through a distributed open platform that integrates network, computing, storage, and application core capabilities. Since edge computing data analysis and processing are completed on the edge side, it can generate faster network service responses and meet the real-time, security, and privacy requirements of data processing. Cloud computing can access historical data of edge computing.

[0003] Smart sensors are sensors with information processing functions. Smart sensors are equipped with microprocessors and integrated with multifunctional sensors. They can collect, process and exchange information and are characterized by high precision, low cost, automation and multi-functions.

[0004] Environmental perception refers to the collection of parameters of the surrounding environment through sensors and other devices, such as detecting the distance and relative position of surrounding active objects and equipment, detecting the environment's temperature and humidity, light intensity, soil temperature and humidity, and plant electrical signals.

[0005] Long-distance wireless communication refers to the low-power long-distance transmission of terminal device data, such as sensor data, through solutions such as the LoRa communication protocol. It can extend the distance by 3-5 times compared with traditional wireless RF communication at the same power consumption, reduce the energy consumption of terminal devices, extend the battery life, and reduce the cost of deploying sensors over a large area.

[0006] The combination of edge computing technology, smart sensor technology, environmental perception technology and long-distance wireless communication technology provides more intelligent, customized, low-cost and rapidly deployable services for intelligent detection and perception of plant growth environments in outdoor scenes. For example, for outdoor parks, gardens and agricultural scenes, smart sensors with environmental perception functions can collect environmental temperature and humidity, light intensity, soil temperature and humidity, plant electrical signals, and detect the displacement of people in the environment under privacy-free conditions through artificial intelligence algorithms through distance detection modules. Edge computing devices use multi-model data analysis algorithms to fuse multiple sensor data to analyze the growth status and population density of park plants at the location of the device. For example, by analyzing the biovoltage of plants to detect plant water shortage, combined with the current light intensity, soil and environmental temperature and humidity, and the density of people around the device, and give plant watering tasks that improve the plant growth environment and do not affect the people in the area, and send the data to the control center through long-distance wireless communication technology, which will complete the allocation of watering tasks or automatically control the watering system to complete the watering tasks, thereby improving the survival rate and aesthetics of the plants in the park, reducing operating costs, and avoiding unnecessary troubles and property losses caused by watering tasks to people in the environment. However, in existing technical solutions, edge computing devices, smart sensors, and environmental perception devices are usually independent products that do not have long-distance wireless transmission capabilities, making it impossible to flexibly configure and quickly deploy the three in specific application scenarios. In addition, the costs of developing, hardware costs, installation and deployment, and operation and maintenance management of the three platforms are relatively high. Summary of the invention

[0027] Figure 4 A module structure diagram of a printed circuit board 200 of an outdoor edge computing smart sensor 100 is shown. DETAILED DESCRIPTION

[0028] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0029] Figure 1 , Figure 2 Axonometric diagrams of an edge computing smart sensor 100 with environmental perception and long-distance wireless communication functions in two different directions are respectively shown according to an embodiment of the utility model; Figure 3 The front view, left view, right view, top view and bottom view of the outdoor edge computing smart sensor 100 are shown; Figure 4 A module structure diagram of the printed circuit board 200 in the outdoor edge computing smart sensor 100 is shown.

[0030] like Figure 1 , Figure 2 As shown, the outdoor edge computing smart sensor 100 includes a first shell 110 and a second shell 120. The first shell 110 and the second shell 120 are fixedly connected to form a hollow chamber 130. It should be noted that since the chamber 130 is an internal space formed by the first shell 110 and the second shell 120, it is difficult to mark it on the outside. Figure 1 , Figure 2 The chamber 130 is not marked. According to one embodiment, the first housing 110 is provided with a plurality of through holes 112, and the second housing is provided with threaded holes (threaded holes are provided at the bottom of the housing) that can be matched with the through holes 112. Figure 1-Figure 4 (not shown), accordingly, the first housing 110 and the second housing 120 are fixedly connected by screws. Of course, in addition to screw connection, other connection methods such as snap connection can also be used to fix the first housing 110 and the second housing 120 together, and the utility model does not limit the fixed connection method of the first housing 110 and the second housing 120.

[0031] A printed circuit board 200 is arranged in the chamber 130, and a microcomputer module 210, a distance detection module 220, a communication module 230, a display screen 240, a battery module 250 and at least one environment perception sensor 260 are arranged on the printed circuit board 200. The printed circuit board 200 can be fixed in the chamber 130 by screws (such as self-tapping screws), or can be fixed in the chamber 130 by bonding. The utility model does not limit the fixing method of the printed circuit board 200 in the chamber 130. The microcomputer module 210, the distance detection module 220, the communication module 230, the display screen 240, the battery module 250 and at least one environment perception sensor 260 can be fixed on the printed circuit board 200 by welding, screws (such as nylon screws) or other methods.

[0032] It should be noted that the microcomputer module 210 can be of any model and any size, and the present invention does not limit the model and size of the microcomputer module 210. For example, the microcomputer module 210 can be an Espressif single-board microcomputer (ESPRESSIF ESP32-S2). In addition, the present invention does not limit the model of the distance detection module 220. For example, the distance detection module 220 can be a Hailingke 24G millimeter wave radar module (HLK-LD2450). It should be noted that the distance detection module 220 is used to detect the distance between the surrounding objects and the device, and it must be in a sealed environment to meet the requirements of outdoor waterproofing. Accordingly, the shell in front of the distance detection module 220 must be a transparent material. According to one embodiment, the first shell 110 or the second shell 120 is made of a transparent material, for example, Figure 1 , Figure 2 As shown, the first shell 110 is made of transparent PC material, so that the radar signal of the distance detection module 220 can penetrate the shell.

[0033] The microcomputer module 210 further includes a processor 211 and at least one expansion interface 212. The distance detection module 220, the communication module 230, the display screen 240, the battery module 250 and the at least one environment perception sensor 260 are connected to the microcomputer module 210 via the expansion interface 212. The processor 211 may be, for example, an Xtensa® 32-bit LX7 single-core processor, but is not limited thereto. The expansion interface 212 may include, for example, an I2C bus interface, a GPIO interface, a sensor interface, a power interface, etc., but is not limited thereto.

[0034] like Figure 1 As shown, the second housing 120 is made of aluminum alloy material, which has good thermal conductivity, and a protruding structure heat-conducting device 129 is provided on the first panel 128 of the heat-dissipating structure of the second housing 120 close to the battery module 250. The heat-conducting device 129 can effectively absorb the heat in the chamber 130 and conduct it to the first panel 128 of the heat-dissipating structure of the second housing 120, and dissipate heat through air circulation, thereby reducing the operating temperature of the overall device and improving the battery life and operating life of the overall device.

[0035] According to one embodiment, the environmental perception sensor 260 includes: one or more of an environmental temperature and humidity sensor, an environmental light intensity sensor, a soil temperature and humidity sensor, a plant electrical signal sensor, a volatile organic compound concentration sensor, a PM2.5 particle sensor, a carbon dioxide concentration sensor, and a sound sensor. Those skilled in the art can arrange suitable environmental perception sensors 260 according to actual needs. The utility model does not limit the type, quantity, and model of the environmental perception sensors 260 arranged on the printed circuit board 200. For example, Figure 4As shown, the environmental perception sensor 260 includes: an environmental temperature and humidity sensor 260-1, whose model may be, for example, SHT30; an environmental light intensity sensor 260-2, whose model may be, for example, TEMT6000; a soil temperature and humidity sensor 260-3, whose model may be, for example, SHT30; a plant electrical signal sensor 260-4, whose model may be, for example, MAX4080; a volatile organic compound (VOC) concentration sensor 260-5, whose model may be, for example, SGP40; a PM2.5 particle sensor 260-6, whose model may be, for example, SPS30; a carbon dioxide concentration sensor 260-7, whose model may be, for example, STC31; and a sound sensor 260-8, whose model may be, for example, LM386. It should be noted that since the ambient temperature and humidity sensor 260-1, the soil temperature and humidity sensor 260-3 and the plant electrical signal sensor 260-4 need to directly detect the temperature and humidity of the environment and the plant electrical signals, the ambient temperature and humidity sensor 260-1, the soil temperature and humidity sensor 260-3 and the plant electrical signal sensor 260-4 need to be designed with an external electrode interface or a signal interface, and the electrodes or part of the sensor elements are exposed to the external environment. Accordingly, according to one embodiment, a through hole suitable for exposing the external electrodes or sensor element connecting wires of the ambient temperature and humidity sensor 260-1, the soil temperature and humidity sensor 260-3 and the plant electrical signal sensor 260-4 is provided on the first shell 110 or the second shell 120, for example, Figure 1~Figure 3 As shown, a through hole 124 is provided on the first shell 110, so as to facilitate the exposure of the external electrodes or sensing elements of the environmental temperature and humidity sensor 260-1, the soil temperature and humidity sensor 260-3 and the plant electrical signal sensor 260-4. In addition, it should be noted that when a plurality of environmental sensing sensors 260 are provided on the printed circuit board 200, those skilled in the art can design the arrangement of the plurality of environmental sensing sensors 260 according to actual conditions, and the present utility model does not limit this. According to a preferred embodiment, as Figure 1~Figure 4 As shown, the ambient light intensity sensor 260-2 is disposed near the top of the first housing 110 made of transparent PC, so as to avoid reading errors caused by light being blocked by other components in the cavity as much as possible, and the measurement is more accurate. In addition, other environmental perception sensors should also consider the actual measurement target, place some electrodes or sensor elements outside the cavity 130, and transmit data through the sensor signal interface on the printed circuit board 200 via the data connection line, so as to truly collect the surrounding environment information and make the measurement value more accurate.

[0036] According to one embodiment, Figure 4 As shown, the microcomputer module 210 also includes a waterproof power interface 213. Figure 1 , Figure 3As shown, the second housing 120 is provided with a through hole 125 suitable for exposing the waterproof power interface 213. Figure 1 , Figure 3 In the embodiment of the present invention, the through hole 125 is provided on the second shell 120, but in other embodiments, the through hole 125 can also be provided on the first shell 110, and the utility model does not limit the specific position of the power through hole 125. According to one embodiment, the power interface 213 is a USB Type-C interface, and the microcomputer module 210 receives a 5V voltage supply via the waterproof power interface 213 for the operation of the device and charging the battery module 250. When the external power supply cannot supply power, the battery module 250 will provide 5V power. According to one embodiment, the waterproof power interface 213 can be connected to an external solar photovoltaic panel device to charge the device when daylight conditions are met, and the battery module 250 is powered at night, which can meet the need for wiring in a large range, and can complete the rapid and large-scale deployment of the device.

[0037] According to one embodiment, Figure 4 As shown, the WeChat computer module 210 also includes a waterproof external communication interface 214, and the waterproof external communication interface 214 includes a waterproof 3.5MM round hole interface or a USB Type-C interface. It should be noted that the utility model does not limit the number of waterproof 3.5MM round hole interfaces or USB Type-C interfaces included in the waterproof external communication interface 214. Of course, in addition to the waterproof 3.5MM round hole interface or USB Type-C interface, the waterproof external communication interface 214 may also include other interfaces, such as an HDMI interface, a VGA interface, etc., but is not limited to this. It should be noted that the waterproof external communication interface 214 is used to connect to an external device, and accordingly, a through hole suitable for exposing the external communication interface 214 should be provided on the first shell 110 or the second shell 120. For example, as Figure 2 , Figure 3 As shown, a through hole 126 is opened on the second shell 120 , and the position of the through hole 126 corresponds to the position of the external communication interface 214 .

[0038] According to one embodiment, the communication module 230 provided on the printed circuit board 200 is a LoRa module, so that the microcomputer module 210 can upload data to the server through the communication module 230. The communication module 230 can be, for example, a LoRa module, and the model can be SX1262, but is not limited thereto.

[0039] According to one embodiment, Figure 1 to Figure 3As shown, the second housing 120 is provided with a mounting hole 127 on its exterior. The mounting hole 127 is provided with a fixing hole suitable for screwing a stud into, so that the outdoor edge computing smart sensor 100 can be fixed to the ground or soil surface by a rod equipped with a stud. Figure 1~Figure 3 The mounting holes 127 in the embodiment are arranged on the second housing 120, but in other embodiments, the mounting holes 127 may also be arranged on the first housing 110. The present invention does not limit the specific position of the mounting holes 127 on the device 100, as long as it can achieve the fixation of the device 100. Of course, in addition to setting the mounting holes 127 and using studs to fix the device 100, other methods such as bonding, hanging, etc. may also be used to fix the device 100 in the surrounding environment. The present invention does not limit the specific fixing method of the device 100.

[0040] According to the technical solution of the utility model, the environment perception sensor 260 collects environmental data at a predetermined frequency (for example, once per second), and the processor 211 of the microcomputer module 210 receives the environmental data collected by the sensor 260 and processes it (including removing abnormal values, calculating average values, filtering, etc.), and then packages the processed data and uploads it to the server. In addition, the processor 211 collects the data collected by the environment perception sensor 260 at a preset frequency (for example, once every 5 seconds), uses a multi-model data analysis algorithm to fuse multiple sensor data, analyzes the health status of the park plants and the density of people at the location of the device, and provides a plant watering task that adapts to the natural environment of the device and does not affect the people in the area. The communication module 230 uploads the data to the server through long-distance wireless communication technology at a preset frequency (for example, once every 5 seconds).

[0041] The technical solution of this utility model integrates edge computing intelligent sensors, environmental perception equipment, and long-distance wireless communication functions into one, which is easy to install and deploy and flexibly configure, saving hardware costs, deployment costs, and operation and management costs. In addition, the equipment of this utility model collects environmental data through distance detection sensors and environmental perception sensors, and processes data locally through microcomputer modules, realizing centralized data collection and centralized processing, and ensuring the real-time nature of data processing.
