Abstract

The invention relates to an intelligent transportation system of a PLC. The system comprises an induction coil group buried in the road, a PLC control platform which comprises an inductive detector, a comparison discrimination circuit and a pulse output circuit which are in mutual coupling, wherein the inductive detector is connected with the induction coil group. According to the intelligent transportation system of the PLC and the control method thereof, through the statistics of traffic flow, the programmable logic controller (PLC) is employed to design an intelligent traffic light control system to solve the traffic congestion, the traffic efficiency of a crossroad is rapidly improved, and the red light waiting time of a vehicle is reduced.

Description

technical field [0001] The invention relates to an intelligent regulation system, in particular to a PLC intelligent traffic system and a regulation method thereof. Background technique [0002] Today, with the increasing economic development, the traffic flow in cities is also increasing, and traffic jams have become a concern of the whole society. In view of the current situation of urban traffic congestion in our country, it is an effective way to solve this problem by rapidly improving the traffic efficiency of intersections and reducing the time for vehicles to wait for red lights. However, some schemes and measures are not mature enough or the methods are complicated or the cost is too high and the construction is inconvenient, etc., which are difficult to promote and realize. Contents of the invention [0003] The object of the present invention is to provide a PLC intelligent transportation system with convenient implementation and low cost and its control method....
