Abstract: With rapid development of computer technology,communication technology and intelligent sensor technology, the monitoring of power equipment has also embarked on the road of intelligence and automation. In order to better ensure the stability and safety of power equipment, more and more chemical, mechanical, thermal and other non-electric parameters are integrated into the related monitoring system at the present stage. Based on artificial intelligence, Internet of things and other technologies, a multi physical quantity integrated perception and early warning device with edge computing and collaborative analysis functions are developed,which has been verified and promoted in the demonstration project of Qingdao Power Supply Company in Shandong Province, providing effective technical means and solutions for the construction of the Internet of things of power transmission and transformation equipment.
