Abstract

The invention discloses an intelligent traffic light control system based on a PLC and a sensor. The intelligent traffic light control system comprises detectors, a PLC, an east road, a west road, a south road, a north road and a traffic control center; detectors are arranged on the roads toward the east, the west, the north and the south from the crossroad; the detector comprises a sensor node, a common WSN node and a Sink node; the sensor node transmits data and information through a common WSN node; the Sink node transmits the information converging on the WSN node to the PLC for processing; the PLC is connected to the traffic control center through an external network; the Sink node, the common WSN node and the sensor constitute a ZigBee local area network. In the invention, the WSN is adopted as an emerging application technology, and the intelligent traffic light control system is small in volume, low in cost, small in power consumption and flexible in network combination, and the wide application of the invention can change people's life. The intelligent traffic light control system combines the MSN and the PLC, and can determine whether the road in the direction is busy according to the quantity of the stranded vehicles waiting for the traffic light. The intelligent traffic light control system is simple and economic, can effectively ease the traffic jam, improves the passage capability of the traffic intersection and has a good application prospect.

Description

technical field [0001] The invention relates to a traffic light control system, in particular to an intelligent traffic light control system based on PLC and sensors. Background technique [0002] Setting up traffic lights at intersections can effectively unblock traffic and provide a strong guarantee for the safety of traffic participants. But with the rapid development of society and economy, the original traffic light control system can no longer adapt to the increasingly busy traffic conditions. How to improve the traffic light control system and make it adapt to the current traffic conditions has become a research topic. The usual way of traditional traffic control lights at crossroads is: through the investigation of vehicle flow in advance, the time delay of traffic lights in two directions is pre-set by using statistical methods. However, in fact, the change of vehicle flow is often uncertain, and some intersections may even have great differences in different time...
