Power monitoring system of fire fighting apparatus

Abstract

The invention discloses a power monitoring system of a fire fighting apparatus. The power monitoring system comprises a fire fighting apparatus power monitor and sensors, the sensors comprise a single-phase voltage/current sensor, a voltage sensor and a current sensor, the fire fighting apparatus power monitor is communicated with the sensors through a CAN bus, and a Modbus-RTU communication protocol is provided for the outside. The power monitoring system has the advantages of being reliable, real-time, digitalized, intelligent, networked and automatic and achieving continuous monitoring, the condition of a power source of a monitored device is reflected in real time, and is displayed in a centralized mode, and therefore the emergent condition that when a fire disaster happens, due to the power failure, the fire fighting apparatus cannot normally work can be effectively avoided, and the reliability of a fire fighting linkage system is ensured to the greatest extent.

Description

technical field [0001] The invention relates to the field of fire-fighting equipment, in particular to a fire-fighting equipment power monitoring system. Background technique [0002] In recent years, it is not uncommon for various types of fire-fighting equipment to fail to operate normally when a fire breaks out. It is also common for local fire departments to find that fire-fighting equipment is useless in their daily fire inspections. Numerous experiences and lessons have proved that whether the fire alarm is timely and accurate and whether the initial fire is successfully extinguished or not, one of the important prerequisites is whether the fire-fighting equipment can play a role, and the power supply of the fire-fighting equipment is a key to ensure the normal operation of the fire-fighting equipment. fundamental problem. The fire safety of a building largely depends on the working status of the power supply. Because the power supply of fire-fighting equipment does...

AI Technical Summary

Problems solved by technology

Because the power supply of fire-fighting equipment does not work and the fire-fighting water pump does not start, the fire site is short of water and the fire cannot be extinguished. As a result, the fire shutters and fire doors of the fire compartment cannot be put in place, and the spread of the fire cannot be controlled. The smoke exhaust fan cannot be activated and cannot exhaust smoke. The stairwell cannot prevent smoke, the fire elevator cannot
