摘　　要：介绍了一种基于PLC和GPRS的交通信号灯监控系统,详尽地阐述了监控系统的总体方案,远程无线通讯,及其系统的具体实现方法。针对城市交通的不确定性,随机性等特点,提出了用PLC对信号灯进行模糊控制的策略。又给出了具体的实验过程及调试方法,实验表明采用模糊控制策略具有很强的鲁棒性和抗干扰能力。通过专用S7-200的GRPS无线数据通讯模块MD720-3对交通灯进行远程监控及其数据的传输,其传输速率快,实时性好,实现了分布式系统的远程无线监控。A kind of traffic lights monitoring system based on PLC and GPRS was introduced, detailed ex- pounds the overall scheme of the monitoring system, remote wireless communications and its concrete realiza- tion method of the system. According to the characteristics of uncertainty and random of the urban traffic, a fuzzy control strategy of PLC in light was presented. And give a specific experiments and debugging method and the simulation results show that the fuzzy control strategy has good robustness and the anti-interference ability. Through the special S7 - 200 GRPS of wireless data communication module MD720 - 3 for remote mo- nitoring traffic lights and data transmission, the transmission speed, good real-time, distributed the system of remote wireless monitoring.
