Abstract：In order to detect a leakage of SF6 gas in high voltage distribution room and ensure the safety of maintenance and in?spection personnel,the design of the SF6 gas leakage monitoring and alarming system based on STM32 is put forward. The system us?es STM32F103 microprocessor as the core,uses high-precision SF6 infrared sensor and O2 electrochemical sensor. It collects the gas concentration information and transmitted to the STM32 for data processing and display. When the SF6 gas concentration overran or hypoxia,the system gives the sound and light alarm,and starts air exhaust device. The system communicates with PC by the RS232 bus to achieve data transmission and storage. Experimental result show that the system has high precision,good stability,fast re?sponse and other excellent performance.
