The intelligent fire equipment power monitoring system is developed based on the national standard "Fire Equipment Power Monitoring System". The system consists of a fire equipment power status monitor, a power bus, a communication bus, and connected current signal sensors, voltage signal sensors, current/voltage signal sensors, intermediate module boxes, and other devices. Through sensors, the main and backup power supplies of the fire equipment are detected in real time to determine whether the power equipment has overvoltage, undervoltage, overcurrent, open circuit, short circuit, and phase loss faults. When a fault occurs, it can quickly display and record the location, type, and time of the fault on the monitor, and emit sound and light alarm signals, effectively ensuring the reliability of the fire linkage system in the event of a fire.
