Abstract


This paper describes the design and implementation of online monitoring alarm system which is a set of technologies based on Zigbee network communications high-voltage switch room SF6 Gas and oxygen concentration. Designers deeply research and analyze the SF6 Gas detection technology on the current, and they use microcontroller unit technology to resolve the digital sampling and data processing; The design use double high-voltage dynamic micro-detection method to resolve SF6 Gas Sensor of low accuracy sampling and running-short and it uses reliable Zigbee networking technology to realize the wireless communication between monitoring unit and control host, and to resolve difficult problems of installation, maintenance,expansion and construction. The system realizes SF6 and O2 gas concentrations of online monitoring and gas concentration limit alarm and in high-voltage switch room, and starting the ventilation devices at the same time, thus resolving the safety of person’s life who working in high-voltage switch room.
