【正文】 . 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 traffic emergency switch. If there is no emergency lights all work, but when an emergency open. In this case, the car is urgent priority pass. Once the emergency vehicle passes, emergency switch off immediately. The green light in the same direction of the vehicle quickly flashes three times, followed by the normal operation. If you were from the northsouth and eastwest two emergency vehicles, traffic control systems can respond quickly came early, and then another. 2. Traffic Control System Design A. Hardware design CP1H series PLC as controller, display the procedure should stop when the time series of abnormal system operation, the time will not be displayed. When the emergency procedures are pleted time series, countdown display program should be reset. At 220 V AC system is used to control traffic lights, 24 V DC control segment encoder, Figure 2 shows the scheme Eastern time display. CP1H series programmable logic controller (PLC) is a simple controller, which consists of 24 inputs and sixteen outputs. Because the output to twenty In this sys
