Abstract

The invention discloses a traffic light control system, and relates to the field of traffic light control. The system comprises a geomagnetic detector module, a traffic light module and a control host. The control host is connected with the geomagnetic detector module and the traffic light module; the geomagnetic detector module is used for detecting vehicle information at an intersection; the geomagnetic detector module comprises a first geomagnetic detector and a second geomagnetic detector; the first geomagnetic detector is arranged at a first detection point of an entrance of the intersection, the second geomagnetic detector is arranged at a second detection point of the entrance of the intersection, and the distance between the first detection point and the intersection is smaller than the distance between the second detection point and the intersection; and the control host is used for judging the traffic jam condition of the intersection according to the vehicle information detected by the geomagnetic detector module and controlling the work of the traffic light module. According to the system and a method provided by the invention, the low-cost detection of the vehicle information is realized through the geomagnetic detector, and then the traffic lights are controlled through the vehicle information so as to relieve the traffic jam condition.

Description

technical field

[0001] The invention relates to the field of traffic light control, in particular to a traffic light control system and method. Background technique

[0002] In recent years, due to the increase in the number of motor vehicles, the phenomenon of traffic congestion continues to occur, and the importance of traffic light control is also increasing day by day. In the prior art, traffic lights are controlled through video images or infrared sensors to count traffic flow data, and the traffic control host adjusts the duration of traffic according to the size of traffic flow. The algorithm of traffic flow statistics through video images is relatively complex and requires high hardware requirements. The traffic flow data is counted by the infrared sensor, which is greatly affected by the weather. The traffic flow acquisition equipment used in these methods not only has high cost, but also requires a large amount of construction, and the installation cost is also v...
