基于PLC的消防报警系统模块设计改造

摘要

对消防报警的控制电路图在PLC的基础上进行改造，使其只有输入端和输出端。系统设计中以PLC为控制核心，以被监测建的筑物或地点为警戒对象，使用自动化手段实现早期的火灾探测，火灾自动报警和消防设备联动控制。具有安全、稳定、可靠且灵活性强的优点，降低了因误报而带来的损失，提高了消防报警的效率。%Fire aIarm controI circuit is on the basis of the PLC transformation,which onIy has the input and output termi-naI.Regarding PLC as the controI core,the monitored buiIdings or sites as the aIert object and using automation,the system can achieve earIy fire detection,automatic fire aIarm and fire controI Iinkage equipment automatic fire extinguishing system.It is a safe,stabIe,reIiabIe and fIexibIe system,which reduces the Iosses greatIy caused by faIse aIaming.
