Design of Fire and Security Training System Based on PLC
A fire and security training system controlled by PLC was designed,using Mitsubishi FX3U64MR series PLC.The smoke detectors,temperature detectors,and manual alarm buttons of fire system,and the emergency alarm button and passive infrared detector of the security system feed back the signal to the PLC control host,and after being processed by the PLC controller,the output signal is controlled to achieve fire alarm and intrusion alarm.Compared to the original fire and security training system,this system achieves centralized control of the fire and security system,and has good secondary development performance,which can be widely applied to students'practical training and teachers'research projects.
