Embodiment 1

[0029] Such as figure 1 Shown is the system block diagram of the control system that provides priority signals for setting vehicles (such as guard vehicles, official vehicles for special official duties, ambulances for first aid, etc.) of the present invention, which includes

[0030] A plurality of video detection units, which include: a video acquisition device for collecting image information of a driving vehicle; an image recognition module for converting the image information of the driving vehicle into license plate number information; the video acquisition device of this embodiment is 4 cameras set at a certain distance at each intersection, such as figure 2 shown. It is arranged on the lane on the side of the intersection that the vehicle is about to enter in the direction of the incoming vehicle, so as to ensure that only the license plate number of the incoming vehicle can be detected, and the video acquisition unit cannot collect the vehicles passing through the ...

Abstract

The invention discloses a control system for providing a priority signal for a set vehicle. A plurality of video detection units that are arranged on a road apart from a junction for a certain distance are employed to detect license plate number information of a driving vehicle; and a data processing unit compares the license plate number information of the driving vehicle with a stored set vehicle license plate number information; when the information is matched, a priority control signal is sent to a signal light control unit according to a driving direction of the vehicle and a green light signal for passing through with priority is set for a set vehicle. Meanwhile, the invention also discloses a control method for providing a priority signal for a set vehicle by applying the system. According to the invention, problems of complex operation of a control system and low intelligent degree in the prior art can be solved; and the system and the method are widely applied to an urban traffic control system.

Description

technical field [0001] The invention belongs to the field of intelligent traffic control, in particular to a control system and method capable of providing priority signals for setting vehicles. Background technique [0002] Nowadays, on urban roads with large traffic volume and poor road traffic capacity, the problem of traffic jams is becoming more and more serious. Special vehicles (such as guards, official convoys performing special official duties, ambulance convoys for first aid, etc.) pass through intersections controlled by signal lights How to ensure that the clearing signal is obtained quickly and accurately, so that the intersection can be passed quickly, and the traffic lights can be restored to normal after passing the intersection, so as to reduce the impact on normal traffic, which is the primary task of the traffic command center. [0003] The existing Chinese patent document CN 1189850 C discloses a method for quickly generating a green wave control scheme f...
