The main control computer system consists of a central controller, a network communication module, a software analysis module and a control module, wherein the central controller is an AT89S51 single chip microcomputer, and the main control computer system analyzes displacement change of vehicles in vehicle information acquired for multiple times to judge whether traffic lights need to be regulated and controlled. The judgment of traffic light regulation specifically comprises the following steps: when the master control computer system analyzes the vehicle information acquired for many times and obtains that the displacement change of the vehicle does not exceed a set value, judging that regulation and control are not needed; when the master control computer system analyzes the vehicle information acquired for many times and obtains that the displacement change of the vehicle exceeds a set value, the master control computer system judges that the regulation and control are needed; the regulation and control specifically comprises the following steps: when the main control computer system judges that the regulation is needed and the traffic light is changed into the green light, the green light is changed into the red light when the last vehicle in the 90m-100m area in the direction crosses the traffic light.
The intelligent traffic light regulation and control system regulates and controls traffic lights according to commands sent by the master control computer system.
The tracking system is used for tracking and monitoring information of the last vehicle in the acquired vehicle information after the master control computer system judges that the regulation and control are needed, the tracking system is particularly used for monitoring the traffic light intersection area, and the video monitoring system carries out monitoring once every 5 s.
The video monitoring system is a foundation and mainly comprises a camera shooting module and a network information transmission module arranged in the camera shooting module, wherein the camera shoots within a range of 90 meters to 100 meters away from a traffic light, shoots at preset same time intervals such as 5 seconds, and transmits the shot pictures to a main control computer system.
The image preprocessing part is used for filtering and denoising images in the video stream, and reducing the image noise by adopting median filtering; due to the particularity of the installation environment of the traffic monitoring camera, the traffic monitoring camera is extremely inconvenient to maintain, dust is easily attached to the outside after a lens is exposed for a long time, so that salt and pepper noises such as spots appear in an image, the definition of the image is influenced, the medium value filtering can well inhibit the salt and pepper noises of the image, the image is restored to be clear, and the detection accuracy is improved; then, contrast enhancement is carried out by adopting histogram equalization, so that the interference of light rays on the whole image is reduced; after the image is preprocessed, the definition is improved, the visual effect is improved, and the accuracy of subsequent detection is improved.
A main control computer system: the system comprises a central controller, a network communication module and a software analysis module, wherein a main control computer system receives the transmitted pictures, utilizes software to compare and analyze the pictures, judges the traffic jam condition of the traffic light intersection, makes a command according to the analysis and processing result, and sends the command to an intelligent traffic light regulation and control system through the network communication module,
the design of the central controller adopts an AT89S51 singlechip as the central controller, data acquisition is carried out through a sensor, and data are transmitted to a control center through an A/D converter for data analysis and comparison.

A tracking system: the system may function to track whether the last vehicle has completely passed the intersection. If the traffic light passes, the traffic light turns to red light.
When the signal lamp becomes the red light, the video monitoring system in the red light direction starts to work at the moment, the monitoring road section is photographed every 5 seconds, the photographed photos in the adjacent time periods are compared, when the comparison result of the photos in the adjacent time periods is almost unchanged, whether the situation belongs to a waiting overlong stage or not is judged, and if the situation does not belong to the waiting overlong stage, the signal lamp runs the original signal lamp control system. When the waiting too long stage is judged, the main control computer judges whether the vehicle tracked and monitored in the green light driving direction has driven through the crossroad or not. If the vehicle passes through the intersection, the main control computer sends an instruction to the control system, the control system controls the signal lamp to change into green, and the control is finished. And if the tracked and monitored vehicle does not pass through the intersection in the green light driving direction, waiting, judging once every five seconds until the tracked vehicle passes through the intersection, and performing the next step.
