Detailed Description

As shown in fig. 1 to 8, the traffic control device based on the front-end camera access platform provided in this embodiment includes a signal lamp regulation mechanism, a water spray warning mechanism and a mounting assembly.
As shown in fig. 1 and 2, the signal lamp regulation mechanism comprises a camera 34, a crowding degree analysis module, a central controller and a traffic signal lamp 33 which are sequentially connected in a signal mode, a lamp bracket 32 is arranged on one side of a road, and the traffic signal lamp 33 and the camera 34 are arranged on the lamp bracket 32. The congestion degree analysis module analyzes the vehicle congestion degree according to the vehicle picture collected by the camera 34, the central controller regulates the traffic signal lamp 33 according to the vehicle congestion degree, and the vehicle congestion degree is in direct proportion to the green light display time of the traffic signal lamp 33 in the vehicle passing direction. The crowding degree analysis module can also analyze the crowding degree of the pedestrians according to the pedestrian images collected by the camera 34, and the central controller regulates and controls the traffic lights of the sidewalk arranged on two sides of the sidewalk according to the crowding degree of the pedestrians, wherein the crowding degree of the pedestrians is in direct proportion to the green light display time of the traffic lights of the sidewalk in the pedestrian passing direction. If the crowding degree of the vehicle and the pedestrian is higher, the green light display time of the traffic signal lamp 33 and the pavement traffic light is correspondingly prolonged respectively.
The water spraying warning mechanism comprises a human body infrared sensor 21, a warning line 35, a speed-reducing air compressing mechanism and a water spraying mechanism, wherein a plurality of groups of speed-reducing air compressing mechanisms are arranged side by side in the width direction in the right-leaning area of the motor vehicle lane, the water spraying mechanisms are symmetrically distributed in two groups relative to the sidewalk, the two groups of water spraying mechanisms are respectively positioned above two sides of the sidewalk, and the passing direction of the sidewalk is perpendicular to the passing direction of the motor vehicle lane. The warning line 35 is arranged on the ground below the water spraying mechanism, the warning line 35 can be L-shaped, and can warn nearby two adjacent sidewalks. The human body infrared sensor 21 is in communication connection with the central controller; when the human body infrared sensor 21 detects that a pedestrian crosses the warning line 35 to break the red light, the decelerating air compressing mechanism triggers the water spraying mechanism to spray water to the side, close to the sidewalk, of the warning line 35 when the decelerating air compressing mechanism is rolled by a vehicle. The sprayed water can be common urban water, and can be tap water, fire-fighting water and other public water, and also can be rainwater. In winter, antifreeze can be added to prevent water from freezing. In order to improve the water spraying warning effect, pigment with color can be added into water, and the pigment can be attached to clothes or bodies of pedestrians when the water is sprayed out, so that the pedestrians are less likely to try to break the red light when knowing that the pedestrians break the red light to possibly spray the colored water, and after the pedestrians are sprayed with the colored water, washing products such as washing powder, washing liquid, bath cream and the like can be used for cleaning clothes and dirt on the bodies.
As shown in fig. 2 and 5, the mounting assembly is used for mounting the human body infrared sensor 21, the speed reducing air compressing mechanism and the water spraying mechanism.
As shown in fig. 2, 3 and 5, a group of water spraying warning mechanisms are respectively arranged on four azimuth roads of the crossroad, and two groups of water spraying mechanisms in the group of water spraying warning mechanisms are respectively positioned on two sides of the crosswalk. The mounting assembly can be used to mount one of each of two sets of adjacent water spray warning mechanisms, each of the two sets of water spray warning mechanisms facing two adjacent sidewalks.
The control method of the traffic control device based on the front-end camera access platform comprises the following steps:
s1, a camera 34 collects vehicle pictures and transmits collected data to a crowdedness analysis module;
s2, analyzing the congestion degree of the vehicle by the congestion degree analysis module, and transmitting an analysis result to the central controller;
s3, the central controller regulates and controls the traffic signal lamp 33 according to the vehicle congestion degree, and the more serious the vehicle congestion degree is, the longer the green light display time of the traffic signal lamp 33 in the vehicle passing direction is, so that enough passing time is provided for the vehicle, and the traffic jam condition is relieved;
s4, rolling the speed-reducing air compressing mechanism when the vehicle normally runs on the motor vehicle lane;
if the human body infrared sensor 21 detects that the pedestrian passes over the warning line 35, namely when the pedestrian wants to break the red light, the decelerating air compressing mechanism triggers the water spraying mechanism to spray water to the side, close to the sidewalk, of the warning line 35 when the pedestrian is rolled by the vehicle, namely to spray water to the pedestrian needing to break the red light, and the pedestrian is warned to stop the behavior of breaking the red light;
if the human body infrared sensor 21 does not detect that the pedestrian passes over the warning line 35, namely, when the pedestrian does not break the red light, the speed-reducing air compressing mechanism cannot trigger the water spraying mechanism to spray water when being rolled by the vehicle, so that the water source is saved.
According to the embodiment, when the pedestrian wants to break the red light, the pedestrian can be warned in a water spraying mode so as to prompt the pedestrian to stop breaking the red light. When the vehicle is running normally, it is determined whether the speed-reducing air compressing mechanism is effective to trigger the water spraying mechanism to spray water according to whether the human body infrared sensor 21 detects that the pedestrian passes over the warning line 35. If the pedestrian passes over the warning line 35, when the vehicle rolls the speed-reducing air compressing mechanism, the speed-reducing air compressing mechanism can trigger the water spraying mechanism to spray water to the pedestrian passing over the warning line to warn, thereby prompting the pedestrian to stop running the red light, preventing the traffic from being blocked and preventing traffic accidents. If the pedestrian does not cross the warning line 35, the water spraying mechanism is not triggered to spray water even if the decelerating air compressing mechanism is rolled by the vehicle. When the speed-reducing air compressing mechanism is rolled to the limit degree by the vehicle, the top end of the speed-reducing air compressing mechanism is still protruded on the ground, so that the speed-reducing effect on the vehicle can be achieved, the vehicle can be driven in a speed-reducing way when passing through a road intersection, and the traffic accident rate near the road intersection is further reduced.
