[0021] The micro-power wireless uses a 2.4G / 470M dual-mode micro-power wireless, and 2 paths are set for each of 2.4G / 470M; the LoRa transparent transmission uses a 470M LoRa transparent transmission, and 2 paths are set.

[0022] In this embodiment, for the 4G / 470M dual-mode micro-power wireless interface, 2 paths are set for each mode, which meets the requirements of the communication protocol standard of the micro-power wireless network for power transmission and transformation equipment Internet of Things, and is suitable for connecting Internet of Things devices with short distance and low power consumption, such as sensors for contact temperature measurement, switch cabinet partial discharge, environmental temperature and humidity, etc.;

[0023] There are 2 paths of LoRa transparent transmission. Using LoRa (Long Range) low-power wide-area network technology, it realizes long-distance and low-power data transmission. The transparent transmission function ensures the direct transmission of data from one end to the other end, without additional data processing on the gateway, and is used for accessing data of non-standard wireless sensors (non-micro-power wireless);

[0025] There are 2 USB interfaces, 4 100M Ethernet interfaces, 4 RS485 interfaces, and 4 RS232 interfaces.

[0026] In this embodiment, the 4 RS485 interfaces and the 4 RS232 interfaces support half-duplex multi-point communication and full-duplex point-to-point communication respectively, with strong anti-interference ability and long-distance transmission ability, and are mainly used to access controllers such as fans and water pumps.

[0027] The core board consists of a CPU+NPU hybrid processor, memory, and storage.

[0028] When the core board collects data, it communicates with the terminal device through network ports, wireless, RS232, and RS485 communication interfaces, and collects the sensed data into the gateway according to the protocol format of the terminal device.

[0029] When the core board calculates, it analyzes and processes the sensed data of the terminal device collected, and conducts analysis and judgment through an artificial intelligence model. The built-in NPU processor of the core board can efficiently run the artificial intelligence model to accelerate artificial intelligence reasoning.

[0030] When the core board transmits data, it sends the collected original sensed data, calculation analysis, and artificial intelligence reasoning results to the Internet of Things management platform through the 5G / 4G full-netcom module via the APN node.

The collection application is responsible for communicating with the terminal device through communication interfaces such as network ports, wireless, RS232, and RS485, and collecting the sensed data into the gateway according to the protocol format of the terminal device; the calculation application is responsible for analyzing and processing the sensed data of the terminal device collected, and conducting analysis and judgment through an artificial intelligence model. The built-in NPU of the core board can efficiently run the artificial intelligence model to accelerate artificial intelligence application reasoning; the transmission application is responsible for sending the collected original sensed data, calculation analysis, and artificial intelligence reasoning results to the Internet of Things management platform through the 5G / 4G full-netcom module via the APN node.

[0032] In this embodiment, the integrated acquisition and calculation gateway of the present utility model has the following functions: ① Acquisition function: The acquisition function supports access through wired and wireless interfaces such as micro-power wireless, LoRa transparent transmission, RS485, RS232, and Ethernet. For example, it can access 9 types of sensing terminals such as contact temperature sensors, switchgear partial discharge sensors, switchgear temperature and humidity, ambient temperature and humidity, water level, smoke, cameras, fans, and water pumps. In terms of protocols, it supports Modbus RTU, Modbus TCP, the communication protocol of the micro-power wireless network for power transmission and transformation equipment Internet of Things, Onvif protocol, RTSP protocol, etc., and can support custom protocols in the form of upgrading protocol library files. For the unstructured data of partial discharge spectrograms, the acquisition supports collecting data into the gateway through standard protocols and custom protocols. Then, the gateway converts the unstructured data into XML hypertext language for description, and performs GZIP compression processing on the results, converting the processed hypertext content into a string for subsequent transmission;

[0033] ② Calculation function: The calculation function is divided into two types. One is data calculation and analysis. Based on the data of the 9 types of sensing terminals collected, it analyzes the data change rate and threshold, alarms when the change rate and threshold exceed the limit, and executes linkage strategies. For example, when the ambient temperature and humidity exceed the limit, it alarms and turns on the fan to cool down and remove moisture; when the ambient water level exceeds the limit, it alarms and turns on the water pump to drain water; when the contact temperature rise exceeds the limit, it alarms, etc. The other is artificial intelligence reasoning. The gateway extracts image frames from the RTSP data stream of the camera at a minute frequency and inputs them into an artificial intelligence model (such as safety helmets, water accumulation, fires, people falling, small animal intrusion, etc.) for reasoning and analysis. If a suspected result is identified, it increases the image frame extraction frequency of the RTSP data stream to 5S / frame (can be set), continuously captures the suspected frames and converts them into the Base64 string format, and finally uploads the suspected result and the suspected frames to the Internet of Things management platform to trigger the large model of the artificial intelligence platform for secondary accurate judgment;

[0034] ③ Transmission function: The transmission function mainly transmits the original data of the 9 types of sensing terminals collected, the calculation analysis, and the results of artificial intelligence reasoning and identification to the power grid information intranet platform through 5G / 4G APN; 9 types of sensing data such as contact temperature sensors, switchgear partial discharge (spectrograms), switchgear temperature and humidity, ambient temperature and humidity, water level, smoke, fans, water pumps, image frames, etc., as well as the calculation analysis and the results of artificial intelligence reasoning and identification, are connected to the Internet of Things management platform through the MQTT protocol; The camera video data is connected to the unified video platform through the B interface protocol; In addition, it also supports receiving remote management commands issued by the Internet of Things management platform through the MQTT protocol, such as program debugging and upgrade management operations, to achieve remote operation and maintenance.

It solves the information interaction between the data plane and the control plane and the data acquisition and transmission of unstructured data such as videos and graphs, realizes practical edge computing and edge AI framework, and accelerates the application of artificial intelligence in station room scenarios such as equipment defect identification and video violation identification. During use, this utility model realizes the collection and transmission of unstructured data such as partial discharge spectra and video images on the basis of the existing gateway remote signaling and telemetry data collection and transmission, comprehensively covers the data acquisition and transmission needs of station room equipment and environment (structured and unstructured), and further improves the intelligent level of station room monitoring; this utility model realizes artificial intelligence application on the side, which is different from In the existing gateway artificial intelligence fixed-cycle reasoning and recognition mode, it can dynamically adjust the data collection frequency according to the recognition results and link with the artificial intelligence platform for secondary precise analysis, with higher timeliness and accuracy. Compared with the centralized cloud reasoning mode, it greatly reduces the gateway traffic consumption and improves the practicality of gateway artificial intelligence without sacrificing the timeliness and accuracy of recognition. The utility model uses the communication channel between the Internet of Things management platform and the gateway to realize remote operation and maintenance functions such as program debugging, upgrading, and restarting. The equipment on-site operation and maintenance workload is small, and the operation and maintenance is convenient and fast. The utility model has the advantages of dynamically adjusting the data collection frequency, linking to achieve secondary precise analysis, improving practicality, and reducing the workload of equipment on-site operation and maintenance.
