Design of an Electrical Fire Monitoring and ...

An electrical fire monitoring and warning system based on transducers is designed. The system consists of SCM, drain current detecting circuit, smog detecting circuit and temperature detecting circuit. Electric isolation and protection of the important components in general electrical environment are also designed. Experiments show that, when abnormal temperature, drain current, or smoke happens, the system can carry out data collection, aggregation, comparison, analysis and alarm, achieving the function of automatic monitoring and warning of electrical fire.
