摘　　要：提出了一种由可编程控制器 (PLC)控制的火灾自动探测报警控制器。将烟感、温度探测器接入PLC ,经PLC逻辑判断 ,经专用声光报警集成电路来进行火灾报警、异常报警 (烟感、温感其中之一动作 )、故障报警 ,并发出不同的声光信号、显示出事故类型及位置。本控制器适用于总建筑面积不超过 1 0 0 0m2 的各种地方 ,如图书馆、档案馆、计算机房等处。由于PLC系统集成度高、抗干扰性强、编程简单、系统便于开发、维护及升级 ,因此其结构简单、可靠性强、开发使用及维护的成本都很低 。This article offers us an instrument of fire autoalarm controlled by PLC.It receives fire signal by smoke detector and temperature detector,and analyses logic,then issues different light & sound signals and status messages:Fire Alarm,Unusual Alert,Fault Alert,and shows the places.This instrument can be applied to the places which area less than 1000m 2,for example,libraries,archives and computer rooms etc..This instrument has simple structure and is reliable,and can be developed,maintained and popularized easily and cheaply,because of it′s high integrated and antijamming level,modular system structure and is easy to be programmed.
