Automatic fire alarms and automatic fire suppression systems have become an important part of the building. All along, the operation and maintenance of the fire-fighting equipment power supply system is managed by the equipment maintenance personnel of the property management company. Whether it is normal or not depends largely on the maintenance management mechanism and the responsibility of the maintenance personnel. It cannot guarantee the normal operation of the fire-fighting equipment power supply and fire-fighting equipment. Run effectively. In recent years, fire-fighting equipment has not been able to operate normally in the event of a fire accident due to equipment power failure, causing frequent incidents of heavy casualties and property damage. Especially in the state of tight power supply and long-term environmentally unsatisfactory power equipment, the problem of power failure of fire-fighting equipment is particularly prominent.
In order to realize the real-time management of the fire equipment power supply and eliminate the negligence of manual maintenance, it is necessary to strengthen the fire control room management and real-time monitoring and management of the most important fire equipment power supply through technical measures. GB25506-2010 "General Technical Requirements for Fire Control Room" shall make a mandatory provision for the fire control room. The fire control room shall be able to display the working status and undervoltage alarm information of the power supply and backup power of each fire-fighting equipment in the system. . By setting up the fire-fighting equipment power monitoring system, real-time monitoring and management of the fire-fighting equipment power supply is realized, ensuring the running state of the building fire-fighting equipment is intact, improving the fire safety management level of the building, and eliminating the power failure of the fire-fighting equipment in time to prevent and reduce the fire hazard in the building.
GB28184-2011 "Fire Power Monitoring System" stipulates that the fire power monitoring system is used to monitor the working state of the fire equipment power supply, and can issue an alarm when the power supply has overvoltage, undervoltage, overcurrent, and lack of equal faults, and mandatory fire protection is imposed. Basic functions, test and inspection rules of the power monitoring system.
1 Fire equipment power monitoring system overview
The fire equipment power monitoring system can accurately monitor the fault and abnormal state of the fire equipment power supply, and comprehensively monitor the voltage, current, circuit breaker overvoltage, undervoltage, overcurrent, and lack of equal faults to prevent fire equipment from being used normally. The phenomenon that the fire cannot be effectively controlled and spread is ensured, and the fire-fighting equipment is effectively operated when the fire occurs.
The fire power monitoring system has the characteristics of reliability and real-time performance, and has the functions of digitalization, intelligence, network, automation and real-time monitoring. It monitors the status of the power supply of the equipment in real time and displays it in a centralized manner to solve the problem that the fire equipment fails due to power failure. The problem of operation maximizes the reliability of the fire linkage system.
