In order to reduce safety accidents in university laboratories,an electrical safety management system for laboratories was developed.The system includes terminals,a concentrator and a cloud platform.Through the terminals,the system detects and reads the power information and environmental information from various parts of the laboratory.After being organized through the LoRa network,the concentrator compiles the data from each terminal and uploads it to the cloud platform through 4G DTU.Experimenters show that the system can monitor data and control relevant equipment in the laboratory through mobile or PC devices.This system enables the experimenters to better grasp the real-time electrical status and experimental environment of the entire laboratory,and effectively reduces the occurrence of experimental accidents.
