Remote Monitoring and Fault Detection Technology in Distributed Photovoltaic System

This project studies the intelligent communication terminal based on ZigBee and S3C2440+ 4G dual-layer wireless architecture. It uses ZigBee wireless local area network to collect the information of key equipment of each distributed power plant and transmit it to S3C2440 processor. The embedded network server is constructed by using Linux operating system on S3C2440 processor platform. 4 G module is used to connect the intelligent terminal to the Internet. Users can see all kinds of important data parameters of distributed power plants at any time through the Internet. It has good practicability and expansibility. Collect, store and query the real-time data in serial communication, and realize the setting of the data received by the upper computer to the serial port, the monitoring of the running state of the lower computer, and the setting of the system. Finally, this paper discusses the communication flow of GPRS communication system, the driver program of MC35i, the compilation of AT command and the compilation of communication protocol.
