PAGE I 基于PLC的智能建筑火灾报警与联动控制系统的设计 摘 要 随着我国智能建筑（IB）业的发展，高层建筑及建筑群体越来越多，促使了消防系统以迅猛的速度向前迈进。在智能建筑的建筑物自动化系统（BAS）中火灾报警消防系统是非常重要的一个子系统, 担负着保障人员及财产安全的重任。本课题针对某厂房仓库设计了一个火灾报警与灭火联动控制系统。该设计采用报警延时启动灭火系统的控制模式来减少因早期报警系统的误报给用户带来的损失，同时利用烟雾传感器之间的互锁控制模式，避免了因烟雾在仓库中的扩散而引起其它区域的误报，减少系统的误报率。 关键词：PLC 火灾报警　消防联动 The Design Based On The PLC Intelligent Building Fire Alarm And Linkage Control System ABSTRACT With the development of our countrys intelligent building(IB) industry,there are more and more high building and construction group,which make the fire control system improve with a rapid speed.In the building automation system (BAS) of intelligent buildings,fire alarm control system is a very important sub-system,bearing the responsibility of keeping people and their property safe.My issue is to design a fire alarm and fire linkage control system for one warehouse.It takes the principle that when the alarm time delay then it starts the fire extinguishing systems control model so as to decrease peoples loss because of the alarm system mistakes during the early stage,and it also uses the interlock control model between the smoke sensors in order to avoid the smog diffusion which would cause other regional mistakes in the warehouse,then reduce the systems misinformation rates.
