Description

A temporary traffic signal light at an intersection and a red light capture device

technical field

The invention relates to a temporary traffic signal light at an intersection and a snapping device for running a red light, which belongs to the field of intelligent traffic.

Background technique

Nowadays, electronic monitoring systems for motor vehicles have become popular in cities, especially at intersections equipped with monitoring probes. Once violations are captured by the monitoring probes, points will be deducted and fines will be deducted, so motor vehicles dare not easily violate the rules. However, in some road construction areas, remote areas, and areas with insufficient power supply, traffic lights are about to be built, or fail to be used, and at this time only temporary traffic lights at intersections can be used. However, motor vehicle drivers passing through these road sections often have a fluke mentality because they know that there is no monitoring probe at this intersection. The accident was more serious.

Temporary traffic lights at intersections, such as patents 00223432.7, 02270451.5, 200520105624.6, 201010230177.2 provide a variety of battery-powered easy-to-handle, detachable, height-adjustable mobile traffic emergency signal devices, and patent 201220434205.7 provides solar-powered energy-saving and environmentally friendly mobile Type energy-saving traffic light, 201220584190.2 provides a solar-powered temporary intelligent traffic light with ambient light detector, which can automatically adjust the brightness of the signal light according to the environment, patent 201320216237.4 provides a solar intelligent mobile LED traffic light with ultrasonic detector, Control the display time of traffic lights by collecting traffic flow information on the road.

The above-mentioned temporary traffic lights at intersections provide the function of maintaining traffic order at intersections, and gradually begin to have certain intelligence, including automatically adjusting brightness and controlling display time, but they do not have the function of running a red light to capture snapshots, and cannot take chances on motor vehicles passing through special intersections. members act as a deterrent.

A red light capture device at an intersection, such as patent 200710066500.5, provides a device for video monitoring illegal behavior of vehicles, including: image collector, pan/tilt, supplementary light equipment, traffic lights, processor, recording equipment, transmission equipment and external systems. The processor is connected to the output end of the traffic signal light, and the signal light detection circuit in the processor is a voltage converter, which converts the 0-220V AC voltage output by the red light into a 0-5V DC voltage, and connects it to the serial port of the processor. Patent 200710121793.2 provides a digital camera-based detection system and method for running a red light. It is mainly composed of a digital camera, an industrial computer, and a switch input and output card for transmitting signal light status. The switch input and output card transmits the signal light status by judging the signal light level The red light detection software in the industrial computer obtains the driving information of the vehicle by processing the image of the intersection, and judges whether to run a red light based on the state of the signal light, and then saves the picture sequence or video stream of the vehicle before and after the stop line, and records the current Time, serial number of the picture, lane information of the vehicle, vehicle model size information, vehicle color information and license plate number information. Patent 200910033475.X provides a traffic violation detection method based on video tracking and pattern recognition. The camera captures the intersection video, uses the pattern recognition method to detect the vehicle, video tracking to obtain the movement track, and analyzes the vehicle behavior according to the pattern recognition method and captures it. The output terminals of the traffic lights described in the above three patents are connected to a processor, and the processor realizes the detection of traffic light signals by judging the voltage of the output terminals of the traffic lights.

As another example, patent 201220468489.1 provides an electronic police system based on high-definition video detection, including one high-definition camera, industrial computer and strobe light. The high-definition camera shoots the intersection video, compresses it and transmits it to the industrial computer through Ethernet, and the industrial computer receives and decodes the compressed video stream data in real time, and processes the video stream data frame by frame to detect illegal vehicles , the processing includes: traffic light status detection and vehicle detection, tracking the detected vehicle, and judging the behavior of the vehicle through the tracking track. The strobe light is connected with the high-definition camera by wire, and is used to accept the control of the high-definition camera, and is turned on when the light is dim, so as to provide a shooting light source for the high-definition camera. Patent 201210551907.8 provides a vehicle red-light behavior detection device based on monocular multi-detection surface machine vision. The monocular multi-detection surface high-definition camera simultaneously captures the related images of traffic lights and traffic lights near the stop line of the lane related to the signal light. Through the image Processing technology recognizes the state of traffic lights and the movement of vehicles near stop lines to detect violations. The traffic lights described in the above two patents are detected by taking images of the signal lights with a high-definition camera and using image recognition methods to obtain them.

As another example, patent 200510086976.6 provides an electronic police and intersection machine device and control method. The electronic police that realizes the red light capture function and the intersection machine that controls the traffic light display are installed in a box, and the CCD camera is installed at the intersection through an ordinary cable. The camera monitors the vehicles in four directions at the intersection, and transmits the images of the vehicles to the video acquisition control card. When a vehicle runs a red light, the intersection machine detects it and sends a snapshot to the video acquisition control card. signal, the video capture card captures the red vehicle, recognizes the license plate number at the same time, and then transmits the captured photo and the recognized license plate number to the main control center of the intersection machine. The camera and the intersection machine described in this patent are connected by common cables, and the two are in a separated state.

As another example, patent 201210239881.3 provides a high-definition video-based method for collecting evidence of violations of motor vehicle red light violations. It uses high-definition cameras to shoot video, and uses the target detection and tracking technology of video content to analyze vehicle behavior trajectory. Detect and capture, and form a forensic video at the same time. The state of the traffic signal light can be acquired through image recognition, or directly through traffic light control signals. The images captured by the patented high-definition camera cover traffic intersections, specifically including traffic control lights, zebra crossing areas on the opposite road, intersections and own stop line areas.

The above-mentioned crossing red light capture device is mainly for conventional intersections under normal power supply conditions, through the camera to obtain vehicle behavior and judge and capture illegal vehicles, but at present there is no red light capture device integrated in the temporary traffic lights at the intersection. The temporary traffic lights at intersections and the red light capture device can assist temporary traffic lights and maintain traffic order at special intersections.
