The design of alarm and control system for electric fire prevention based on MSP430F149

This paper introduces an electrical fire control system which is composed of stand-alone electrical fire detector and electrical fire monitoring equipment. The detector with fieldbus communication technologies uses MCU to realize the main route leakage protection for low-voltage 3-phase 4-wire system; at the same time, finish the measure, display and control of voltage, current, power, electricity, temperature and other parameters; through the monitoring equipments have been installed the management software written by VC++, the operation of the scene can be monitored and the alarm information can be detected in time. With RS-485 or Ethernet communication, the system can be associated with kinds of standard power monitoring software, circular monitoring and control more than 250 detects, and record 100 types of faults and data with more than 12 months storage time.
