| Abstract: | This paper studies a project of control traffic light by PLC, and design an Intelligent Transport System by PLC control. This system could self regulation the time of traffic light base on the change of car's flux. Concretely, it use electromagnetic induction loop to detect the car, and count the number of the car by the high speed counter in the PLC system. Base on the principle of Intelligent Control System in this paper, PLC could self regulation the time of traffic light, and reach the best of control. |
