Data Tekecommunications Base Of GPRS Network

With the automobile popularizing and the road construction, economy exchanges between cities are more frequently, traffic is also more and more crowd, it is the one of the society's hot spot problem that how to manage and control the transportation and how to using a road effectively to be in progress. Therefore, all kinds of intelligence traffic system and supervisory control system have arisen at the historic moment, that system with technology of computer, wireless communicating and automation technology and so on. Long-range supervisory control system has very important significance in industrial control field, in a lot of industrial occasion, especially the scene that dispersed and unmanned value guards appears.The wireless data transmission technology has decisive position in intelligence traffic supervisory control system; base on compare current several kinds wireless data transmission technology, in this article, I having chosen the method of GPRS (General Protocol Radio System) which have broad meshing range and completely network coverage range, then I could designed one kind of monitors system owing to network GPRS intelligence traffic light.The control element unit is programming controller that self weaves which control traffic light bright and go out. The centre computer of monitor treatment feedback information which come from the module of GPRS to controller and vehicle rate of flow information which come from vehicle detector, and mix up through controlling treatment then get a time optimizing comparatively and transmit to programming controller that control the traffic lights. So it would improve the road traffic capacity. Adopt the GPRS network to be the data communication platform, it would fully utilize GPRS business's merits: the data transmission rate is high, lower mistake yard rate, the big transmission rate of flow, the lower cost communicating. Overcome the shortcoming that circuit exchange communication waste resource.
