Description

Technical Field

[0001] The present invention relates to a road traffic perception system, and in particular to a road traffic perception system based on a large traffic model. Background Art

[0002] There is usually at least one pedestrian traffic light near the sidewalk, and the switching of the pedestrian traffic light is also preset at a fixed time; for example, the Chinese patent with patent number CN200610155609.1 provides an interactive traffic light control device, which involves a traffic light control circuit structure, including a single-chip control circuit. Its characteristics are: two sets of red, green and yellow light control circuits are set in the single-chip control circuit of the straight direction of the main road, and eight sets of traffic light control circuits are set on the sidewalk crossing the main road. The single-chip input circuit includes a start circuit, a setting circuit, and a reset circuit connected to the input end of the single-chip; the output circuit includes a display circuit and two sets of red, green and yellow light control circuits of the main road in the straight direction and eight sets of pedestrian crossing traffic light control circuits, and its load is a transformer, a rectifier circuit and a matrix circuit of LED light-emitting tubes. The single-chip control transformer is turned on and off in order. When the green light on the main road is on, the sidewalk is on red, and when the red light on the main road is on, the sidewalk is on green. The beneficial effect is that it can ensure that when the main road turns green, motor vehicles can pass through the sidewalks crossing the main road without obstacles, and also ensure the safety of pedestrians crossing the crosswalk. However, there are few pedestrians on some sections of the road, and the fixed time switching of pedestrian traffic lights makes vehicles wait for a long time, which is not conducive to the smooth flow of traffic. Summary of the invention

[0003] The purpose of the present invention is to provide a road traffic perception system based on a large traffic model, which solves the problem that there are few pedestrians on some sections of the road and the fixed-time switching of pedestrian traffic lights causes a long waiting time for vehicles, which is not conducive to smooth traffic.

[0004] In order to achieve the above-mentioned purpose, the present invention provides a road traffic perception system based on a traffic big model, characterized in that the road traffic perception system includes a vehicle traffic light device arranged near a sidewalk, wherein the vehicle traffic light device is provided with a control module, a switch module, a counting module, and a signal receiving module; a vehicle sensor is arranged 100-200 meters away from the traffic light, and a signal transmitting module is arranged in the vehicle sensor; the traffic light is in a green light state in the initial state; the counting module is used to monitor the number of waiting pedestrians in the target area; when the switch module is pressed and the number of waiting pedestrians exceeds a preset value, the control module controls the vehicle traffic light to turn red; when the switch module is pressed and the number of waiting pedestrians is lower than a preset value, the vehicle sensor is turned on, and when the vehicle sensor fails to sense a vehicle for a certain period of time, a signal is generated through the signal transmitting module, and after the signal receiving module receives the signal, the vehicle traffic light is controlled to turn red through the control module.

[0005] Preferably, the counting module includes a high-definition camera arranged on the traffic light. The high-definition camera periodically scans the target area to obtain real-time images. The counting module recognizes the number of people in the obtained images and transmits the number of people information to the control module.

[0006] Preferably, the vehicle traffic light device is also provided with a pedestrian traffic light, and when the vehicle traffic light turns red, the pedestrian traffic light turns green after a delay of 2-3 seconds.

[0007] Preferably, a delay module is provided in the signal transmitting module. When the vehicle sensor fails to sense a vehicle for a certain period of time, a signal is generated through the signal transmitting module after a predetermined delay. After the signal receiving module receives the signal, the control module controls the vehicle traffic light to turn red.

[0008] Preferably, the vehicle traffic light device is provided with a lighting device.

[0009] Preferably, the lighting device is provided with a timing module to turn on the lighting device when a predetermined time period is reached.

[0010] Preferably, switch modules are respectively provided at both ends of the sidewalk.

[0011] Beneficial effects: The present invention provides a road traffic perception system based on a large traffic model, characterized in that the road traffic perception system includes a vehicle traffic light device arranged near a sidewalk, wherein the vehicle traffic light device is provided with a control module, a switch module, a counting module, and a signal receiving module; a vehicle sensor is arranged 100-200 meters away from the traffic light, wherein the vehicle sensor is provided with a signal transmitting module; the traffic light is in a green light state in the initial state; the counting module is used to monitor the number of waiting pedestrians in the target area; when the switch module is pressed and the number of waiting pedestrians exceeds a preset value, the control module controls the vehicle traffic light to turn red; when the switch module is pressed and the number of waiting pedestrians is lower than a preset value, the vehicle sensor is turned on, and when the vehicle sensor fails to sense a vehicle for a certain period of time, a signal is generated through the signal transmitting module, and after the signal receiving module receives the signal, the vehicle traffic light is controlled to turn red through the control module. When the number of waiting pedestrians in the sidewalk monitoring target area is small, priority is given to ensuring the passage of vehicles. When the vehicle sensor cannot sense any vehicle for a certain period of time, the control module controls the vehicle traffic light to turn red to allow pedestrians to pass safely. When the number of waiting pedestrians in the sidewalk monitoring target area is large, the vehicle traffic light is promptly controlled to turn red to ensure that pedestrians pass first. The road traffic perception system provided by the present invention can choose to give priority to vehicle driving or pedestrian passage according to the situation of vehicles and waiting pedestrians on a specific road section, thereby improving the smoothness of traffic on a specific road section.
