Automatic control type traffic light control system

Abstract

The invention relates to a self-controlled type traffic light control system, which comprises a central control unit which is used to control switching actions of traffic lights, wherein the central control unit is provided with a parameter setting and inputting device, a forced switch device and a multistage induction coil detecting device, wherein the multistage induction coil detecting device is mainly composed of a plurality of induction coils which are distributed underground along the extending direction of a road, wherein certain distance is left between the induction coils, a signal output line of each induction coil is switched into the central control unit through a corresponding interface circuit, a vehicle detecting signal is sent to a central processing unit, the central processing unit is used to analyze and operate the vehicle detecting signal, and the vehicle releasing time on different directions and the releasing order on each direction can be automatically adjusted according to the difference of the static vehicle queuing length of each road. The control system can automatically adjust a traffic light control parameter according to traffic flow changes on different directions to improve the traffic efficiency of intersections and to realize the optimum control to the intersection traffic.

Description

technical field [0001] The invention relates to a self-controlled traffic light control system, which is mainly used for controlling traffic signal lights. technical background [0002] The existing traffic light control system is set in the cabinet located on the side of the traffic light road, and the action of the traffic light switch is controlled by the central control unit to realize the sequential conversion of the traffic lights. The control system is equipped with a parameter setting input device and a forced switch device. Input and control the control parameters such as traffic light switching sequence and switching time, and realize the direct control of traffic lights by people through the forced switch device. The defect of this technology is that the control parameters cannot be automatically adjusted according to the traffic flow in each direction. Finally, no matter how the traffic conditions change in each time period, they cannot actively adapt to the traf...

[0002] The existing traffic light control system is set in the cabinet located on the side of the traffic light road, and the action of the traffic light switch is controlled by the central control unit to realize the sequential conversion of the traffic lights. The control system is equipped with a parameter setting input device and a forced switch device. Input and control the control parameters such as traffic light switching sequence and switching time, and realize the direct control of traffic lights by people through the forced switch device. The defect of this technology is that the control parameters cannot be automatically adjusted according to the traffic flow in each direction. Finally, no matter how the traffic situation changes in each time period, it cannot actively adapt to the traffic situation, so that the traffic control at the intersection cannot always be in the best state.
