The electronic police at traffic checkpoints mainly implements functions such as vehicle capture, license plate recognition, network deployment and control, speed measurement, and on-site audio. The communication system adopts a star networking method, that is, a point-to-point structure, one point and one fiber, and each traffic checkpoint is basically a grid. Distributed in a star shape and uploaded to the traffic command center through their respective optical fibers, forming a star optical transmission network. In order to save investment in optical communication channel construction and equipment, TV surveillance images and red light violation records/control information can be multiplexed into an optical terminal and transmitted to the traffic command center. The video can be connected to a large-screen projection system to monitor different intersection conditions. Jiangmen Municipal Traffic Management Bureau uses Tianwei Telecom's multi-service optical transceiver. The middle video interface is mainly used to take pictures of vehicles, and R realizes the control of the on-site pan/tilt. An Ethernet port realizes networking with the center, and the other isolated network port connects to Wanwan. Pixel's high-definition camera and two-way audio realize on-site audio collection and intercom/announcement. If there is a duty point on site, a telephone interface can also be provided to extend the center's telephone switch port to the site to realize internal calls.
