Fire Supervisory System Design Based On Embedded System

This paper designs a fire supervisory system based on ARM9for intelligent building, This system has use of embedded technology, field bus technology, can achieve line inspection, can continuously monitor the building’s fire information through the LCD screen, leakage current, environmental temperature, and power lines operating current. Through this system can keep abreast of information on building’s fire alarm, electrical lines or equipment, changes in parameters of fire danger, failure, and abnormal state. This system has the ability to detect fire hazards, through the alarm as well as terminal linkage device to eliminate fire hazard.This paper research for the fire supervisory system, based on the search of intelligent fire alarm system’s development and has in-depth analysis, paper detailing the system software and hardware design. Paper describes the hardware design, including the concentrated fire mentioning’s overall structure, as well as function and regional fire mentioning’s structure, in order to ensure the fire signals reliability of transmission and real-time, the system uses a bus system for distributed intelligent control method, the two-bus and CAN bus have used in the fire supervisory system to ensure the reliability of system operation. Software design, including the concentrated fire monitoring, the regional fire monitoring and Linux System Migration and related application software design, software design use the top-down design method, this paper has completed the program flow chart and fire supervisory system’s software functional design.This system has high intelligence and reliability characteristics, has certain reference for the development of building fire supervisory system, but there are some areas to be further improved, so in the article finally, the development of fire supervisory system was prospected, and put forward a number of specific ways to improve the system.
