Wireless communication electronic vehicle license and vehicle distance measuring system

Abstract

The invention relates to a wireless communication electronic vehicle license and vehicle distance measuring system which comprises an electronic license device and a vehicle distance measuring integrated information processor and is characterized in that a micro-processing RF transceiver chip, a PCB transceiver antenna, a GPS circuit, a memory chip, a temperature sensor, a time circuit chip, an LIN bus chip, solar batteries and a voltage stabilizing circuit are arranged in the electronic license device; a micro-processing RF transceiver chip, a display circuit, a buzzing circuit, a RFIC circuit and a keyboard circuit are arranged in the integrated information processor; the micro-processing RF transceiver chip and the PCB transceiver antenna in the system are combined with other circuit chips and the peripheral component of each chip to form a wireless communication film circuit; and the film circuit is pressed in a high-strength plastic film by a plastic molding process to form a plastic electronic license. The invention realizes prevention of traffic accidents on highways, supervision of vehicles and monitoring of vehicle license information, and simultaneously realizes miniaturization, convenient installation and use and low cost.

Description

technical field [0001] The invention relates to a "wireless communication vehicle electronic license plate and vehicle distance measurement system", which mainly includes two parts: a wireless communication vehicle electronic license plate and a comprehensive information processor for vehicle distance measurement. It specifically involves wireless ZigBee (communication standard adopts IEEE802.15.4) communication standard vehicle electronic license plates, and a comprehensive information processor for wireless communication vehicle distance measurement; System device for comprehensive processing of information, vehicle license plate information, vehicle GPS information, automatic payment, etc. Background technique [0002] my country's expressway and high-grade road network has been formed, but traffic accidents occur more frequently, and there are many secondary accidents, especially expressway vehicle rear collisions, which often cause many casualties. Due to the randomnes...

AI Technical Summary

Problems solved by technology

Due to the randomness and suddenness of highway traffic accidents, the driver of the vehicle driving on the highway cannot quickly understand the distance information between the nearest vehicle in front and the self-driving vehicle, the speed information of the vehicle in front, and the distance of several hundred meters ahead. The number of vehicles driving within the range, and the traffic information interaction between vehicles driving in heavy fog and heavy rain and vehicles driving ahead

Therefore, there is still no effective means for expressway traffic accident prevention, vehicle supervision, and vehicle monitoring.
