SF6 equipment room safety protection device

The invention provides an SF6 equipment room safety protection device which comprises a single chip microcomputer, a detection module, a liquid crystal display module, a fan control module, a locking module, a monitoring module, an alarm module and a memory module. The detection module, the liquid crystal display module, the fan control module, the locking module, the monitoring module, the alarm module and the memory module are respectively connected to the single chip microcomputer. By designing and integrating multiple modules, gas warning, entrance guard turnoff, fan switching, video monitoring and other functions are achieved, device states and monitoring frames can be displayed and retrieved in real time, a series of problems that existing manual operation is lagged, danger easily occurs and the like are avoided through intelligentized processing, and the manpower cost is greatly reduced.
