The bayonet system refers to the use of advanced photoelectric, computer, image processing, pattern recognition, remote data access and other technologies to monitor motor vehicle lanes and non-motor vehicle lanes in real time and record relevant image data. The front-end processing system analyzes the photographed images and automatically obtains data such as vehicle passing time, place, driving direction, license plate number, license plate color and body color. The obtained information will be transmitted to the database of the control center of the bayonet system through the computer network for data storage, query, comparison and other processing. When a hit-and-run or illegal or suspicious vehicle is found, the system will automatically send an alarm signal to the interception system and relevant personnel.
