Abstract:

In order to further improve the detection accuracy and the response time of fire-fighting equipment power monitoring system, in advance of the traditional monitoring systems, designed a fire equipment supply monitoring system which based on STM32F series microcontrollers core chip, with the use of modern power electronics and advanced intelligent algorithms. The monitoring sensors collect voltage and current signals and switch variable from power supply for fire protection equipment, use RMS and the threshold analysis method to make a preliminary analysis of the data through the high-performance microprocessors. And use S-transform algorithm take signal feature extraction to further judgment and identify the fault signal. The monitoring sensors via RS485 send data to the host monitor to centralize monitoring after processing the data, and it provide Modbus-RTU communication protocol to facilitate data exchange with other external systems, then to display and alarm operation. The tentative results shows that the fire-fighting equipment power monitoring system detects the voltage and current failures accuracy up to 99.18% which based on STM32F, and the response time great to meet the national standard. It can effectively ensure the normal operation of fire equipment supply.
