Abstract
Along with society's development, people's consumption level unceasing enhancement, personal vehicles unceasing increase, the human are many, the vehicle multi-path few road traffic condition was very already obvious. The traffic accident frequency sends, poses the enormous threat to the humanity safety. According to the statistical survey indicated: In the world total population, will have the nearly 19/100000 person to die every year of the traffic accident, this digit may compare with war's in casualty. The vehicles increase the reflection study abroad family's whole progress, but has also brought other negative influences to the people. jinhou ji nian the motor vehicle digit also in sharp growth, the path excess load load bearing, the cause traffic accident year by year increases. In a transportation intersection, if looked like before maintained the transportation by the pure one kind of signal light and traffic police's coordinated is equally insufficient. Therefore, we act according to the topic the request to carry on the design traffic control system based on the new traffic regulations, makes the more reasonable street-traffic control lights and the additional function. In order to satisfy the design the need, selects present in the part performance, the price and so on aspect most feasible components completes the traffic light control system's manufacture. Traffic light's basic function as the core expands the nixietube take Mitsubishi small PLC using driving force very strong CD4511, and uses the configuration software configuration traffic light system to carry on the monitoring. Makes the end product basis actual situation has also made many improvements in the basic traffic light foundation, causes the entire transportation to be more reasonable, the more systematic reduced state of roads occurrence. In addition, our procedure may act according to the different time interval to make the adjustment to the main traffic direction signal, suits like in the peak or the peculiar circumstance transportation demand. This may reduce the busy route most traffic disturbances. This gave people's life to bring the convenience to a great extent, reduced the serious traffic accident's occurrence.
key word: Traffic light PLC configuration monitoring
