We can control the traffic lights by the PLC and MCGS configuration, replace the original relay control, improve the system39。 also discussed in detail the wiring of the hardware and PLC ladder. Traffic lights at the crossroads of the remote monitoring system design configuration software MCGS, realtime monitoring of traffic lights, greatly improving the reliability of data transmission. At the same time, we can configure the traffic lights to change the status of photographs. Keywords: switching power,supply protection, circuit system design 濱州學(xué)院本科畢業(yè)設(shè)計(jì) (外文翻譯 ) 2 1. Introduction With the social development and progress, traffic flow bees increasingly important. On the one hand, too many crossroads, more and more vehicles, which are causing serious traffic congestion. On the other hand, in the limited time it is necessary to maintain the vehicle and pedestrian fast and safe. Therefore, one kind of traffic light control system design, can be used to display time countdown, with puter controlled realtime data. In addition, the configuration technology for realtime images that reflect the traffic lights, understand the historical crossroads of work to get traffic lights visualization. The system consists of host puter and a low puter. MCGS configuration is installed in the host puter is lower by the PLC control system. Normal traffic signal timing diagram shown in Figure 1. But there are some urgent matters, for example. There are a number of ambulances to transport patients to the hospital or to deal with a number of fire engines and fire. Fire engines and ambulances rushed to take precedence over other traffic scene. According to urban traffic control system, under normal circumstances, two control methods and urgency traffic control factors into account. This process can show 14 segment encoder. . traffic lights instant record of the monitoring process. Emergency control signals to control
