A state monitoring method of fire water supply system based on hydraulic pressure mean value

Real-time control of urban fire water supply system status, to ensure the safety and reliability of fire fighting and rescue is of great significance. This paper proposes a method of monitoring the status of urban firefighting water supply system based on water pressure mean. It theoretically analyzed the principle and realization method of sliding filter for hydraulic pressure sensor, and emphatically studied the time domain law of hydraulic pressure signal. The differences in the water pressure mean values in different states of water system were studied in detail. Finally, the effectiveness of the algorithm was verified by the actual leakage test. The results show that the method can obtain the status of the fire water supply system accurately, and monitor the abnormal state of the system in real time, which provide a reliable information guarantee for the fire rescue operation command.
