2、ftware control traffic lights run automatically. in the system, the original line is the program instead of the relay, programmable logic controller (plc) system hardware and software resources to be fair use. normal operation and emergency transport for a detailed description and from the east and

3、west emergencies can be mutually linked. traffic signal systems and two seven-segment digital display in the countdown order; 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, real-

4、time 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 design1. introduction with the social development and progr

5、ess, traffic flow becomes 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 li

6、ght control system design, can be used to display time countdown, with computer controlled real-time data. in addition, the configuration technology for real-time images that reflect the traffic lights, understand the historical crossroads of work to get traffic lights visualization. the system cons

7、ists of host computer and a low computer. mcgs configuration is installed in the host computer 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 hosp

8、ital 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 1

9、4 segment encoder. u.s. 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, emerg

10、ency 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 north-south and east-west two emergency vehicles, traffic control systems can respond quickly came early, and then another.2. traffic

11、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 completed time series, countdown display program should be reset. at 220 v ac

12、 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 system, an i / o m

13、odule must be extended. circuit is shown in figure 2.b. control program designsix timers and two special normal open pulse is used in this system, the green light flashes for all north-south and east-timer and a special pulse; eight kinds of interlocking internal relay is used to implement the urgen

14、cy and transmit pulse two directions to plc, shown in the figure. two sdec instructions are used to display the countdown display the corresponding light. as an important part of the countdown display program, east and west of the green light reflected in the view 4 in these programs downloaded to t

15、he programmable logic controller (plc), all the traffic lights running accuracy, urgency, and things can be interlocked from north to south strictly, all the lights can be set back to the urgency of passing state. therefore, these control program is correct, simple.c. monitoring system computer syst

16、em has two main functions: an output signal acquisition and display real-time status of the programmable logic controller (plc) to control traffic lights, traffic lights. another notification robot status and history of the state real-time curve by examining the history and alarm window. this monito

17、ring system design and configuration software mcgs configuration is easy. the serial communication is implemented as follows.data inspection methods: double endedserial communications number: com0 endedthe minimum sampling period: 200 msprogrammable logic controller (plc) the parameters are defined

18、as follows:the minimum sampling period of the basic properties: 200 msthree read / write channel: x0, x1, x2six read-only access (read u.s. traffic lights): q0-q5 all channels must be connected to a variable defined in a real-time database access visits and other parameters to their default values.

19、after a successful relationship, plc and computer control system is able to change the color of the analog signal lights in the picture on the pc being collected data through the serial port. in contrast, by changing the parameters of the host, the corresponding value is written to the plc internal

20、relay control, intersection traffic lights can be implemented. experimental results show that the system is usually good enough and animation. online monitoring system of traffic lights in figure 5:3. conclusionexperimental results show that the system is usually configured with enough good photos.

21、this system simplifies the programmable logic controller (plc) and the communication between the host computer using industrial configuration software development time is greatly reduced. in particular, more suitable for complex control systems. we can control the traffic lights by the plc and mcgs

22、configuration, replace the original relay control, improve the systems lifetime. at the same time, this method can be applied to control the motor and fluid levels. remote control and configuration combined with the simulation, can be applied to similar control zone.4. references1 whitworth, duller,
