Vehicle GPS positioning distance measuring and vehicle electronic license tag information terminal

Abstract

The invention relates to a vehicle GPS positioning, range measuring and vehicle electronic license plate information terminal which is provided with a mobile vehicle comprehensive information processing instrument and a vehicle-rear electronic license plate information transceiver, wherein the comprehensive information processing instrument is provided with a CPU microcontroller series which comprise a main CPU and a plurality of microunit array CPUs respectively arranged on each microunit array wireless transceiver; a GPS positioning system, a storage, an audio circuit, a display circuit andthe microunit array wireless transceivers are connected to a core CPU microcontroller through communication bus; a voltage stabilizing circuit connected with a vehicle storage battery provides power supply for each circuit and system through the communication bus; the core CPU microcontroller is connected with the vehicle-rear electronic license plate information transceiver through the communication bus. The vehicle GPS positioning, range measuring and vehicle electronic license plate information terminal overcomes the disadvantages that the prior vehicle anticollision system can not operatebecause of radar interference wave and can carry out wireless communication between fore-and-aft vehicles in real time to achieve the aim of preventing traffic accidents.

Description

technical field [0001] The invention relates to a "vehicle GPS positioning distance measurement and vehicle electronic license plate information terminal", referred to as On-Board Unit-OBU for short. It specifically involves the comprehensive information processing instrument of mobile vehicles with wireless communication, the electronic license plate information transceiver at the rear of the vehicle, and the traffic information between vehicles, vehicle distance information, vehicle license information, and vehicle navigation information composed of DCPL communication bus (or CAN bus). processing device. Background technique [0002] Expressways and high-grade road networks in various countries have been preliminarily formed, but traffic accidents occur more frequently, and secondary accidents are also more frequent, especially expressway vehicle rear-end collisions, which often cause many casualties. Due to the randomness and suddenness of expressway traffic accidents, t...
