Multi-branch power parameter monitoring system based on LoRa network

Abstract

The design is a multi-branch power parameter monitoring system based on Lora Network. The system adopts the IM2812B power acquisition module to collect the branch power parameters, the data transmission mainly adopts the Lora and WiFi wireless communication technology as the transmission media, and the transmission protocol is based on the Lora private protocol and the MQTT transmission protocol. The power parameters and environment data of each branch are displayed on the serial port PC and APP through Lora Network, and can analyze the current branch of the electrical appliances and predict the existence of the security risk, make up the existing defects. It is not only to solve the remote monitoring problem, but also to solve the problem of wireless network multi-branch. The system supports the power parameter acquisition with 65,536 branches, and it can greatly reduce the data transmission delay by using the star network and FIFO. After testing, the system's data transmission delay is low and stable. It is easy to layout, and with low maintenance difficulties, it has positive significance for the power parameter monitoring system.
