Abstract:A portable intelligent voice alarm system for live switch gear based on multi-sensor monitoring was designed to solve the hidden danger of electric shock casualties caused by maintenance personnel mistakenly entering live interval when working in live switch gear. The distance between personnel and equipment was judged by pyroelectric infrared sensor and ultrasonic ranging when switchgear was live，and the HW3000 module was used to realize the functions of voice broadcasting，warning and alarm. At the same time，temperature and humidity sensor could monitor the temperature and humidity values of the wire joint in the switchgear in real time to realize the fire warning function，so as to improve the safety and reliability of power operation and prevent the occurrence of power accidents. Experiments showed that the system could realize the functions of early warning and accurate monitoring of temperature and humidity of three-phase wire joints in live switchgear，and had strong practicability and real-time.
