分布式智能消防报警与联动控制系统

Fire Alarm and Joint Control System Based on Distributed Intelligence

消防系统完善程度直接关系智能楼宇的安全,针对消防报警效率低、误报警率高的问题,探讨了一种分布式智能消防报警与联动控制系统。该系统的火灾探测器本身具有微处理功能,可以实现火灾信号与干扰信号的低级判断,利用阀值比较电路对信号阈值幅度进行"滤波",大幅度地减少了主机信号判断的程序量,提高了整个系统的稳定性和可靠性。论述了火灾形成的机理,剖析了导致报警效率低、误报警率高的原因,讨论了火灾报警控制器工作原理、系统框架以及联动控制系统,对分布式智能消防报警与联动控制系统作了探讨。

The perfect degree of fire system is directly related to the security of intelligent building. Aimed at the puzzle that it is lower in efficiency of fire system, and higher in error alert rate, the pa- per explored a sort of fire alarm and joint control system based on distributed intelligence. The fire de- tector of system itself owned the microprocessor function. It could realize the low level judgement of fire signal and interference signal, made the filtering for threshold amplitude by means of comparator circuit in threshold, reduced the program quantity of signal judgement in host computer, and en- hanced the stability and reliability of the whole system. In the paper, it expounded the mechanism of fire disaster production, made the anatomy resulted in cause of being lower in alarm efficiency, and higher in error alert rate, built the system frame of FA system in intelligent addressing, and designed the structure of fire alarm and joint control system. And finally the paper explored the fire alarm and joint control system based on distributed intelligence
