The invention provides a vehicle-mounted electronic police system. The system carries out positioning through the combination of satellite positioning and inertia positioning, and is capable of providing high-precision vehicle positioning data, so that violations or accidents of a vehicle during travelling can be monitored in real time. The system is provided with a travel data recorder for recording the scenes of the violations or accidents. The system can communicate with a server in real time. In addition, the system has expansion interfaces which facilitate connection with various expansion devices. Besides, the system has self-protection functions, specifically including: inertia positioning and satellite positioning are combined, so that the phenomenon that the satellite positioning is shielded can be detected; the vehicle-mounted electronic police main body can carry out real-time recording when the state of communication with the external is changed, and can provide a warning through a state indication device; a traffic checkpoint detection device can detect the situation that a vehicle travels normally but the communication of the vehicle-mounted electronic police is abnormal.
