Highway safety access device and working method thereof

Abstract

The invention provides a highway safety access device with real-time communication and safety protection functions. The highway safety access device comprises a highway safety access card, an on-board unit (OBU) matched with the highway safety access card and a road side unit (RSU) communicated with the OBU. The safety access card is placed in the OBU, communication is carried out by using the dedicated short-range communication (DSRC) technology, and travelling information needing to be paid attention to is told to a driver in real time. In particular, by means of data interaction and operation, accident chains are blocked, and serial harm caused by highway vehicle accidents is reduced to the minimum. According to the highway safety access device, the highway safety access card is locked in the OBU in the whole process, so that vehicles are prevented from evading highway tolls; DSCR is adopted, so communication quality can be guaranteed under bad weather conditions; meanwhile, a DSRC module has an encryption function, and communication safety can be guaranteed.

Description

technical field [0001] The invention relates to the field of expressway communication devices, in particular to an expressway safe passage device and a working method thereof. Background technique [0002] The development of expressways has promoted the rapid development of our country's society and economy, and the safety of driving on expressways has gradually become the focus of people's attention. The expressway adopts fully closed management and has the characteristics of fast driving speed and large traffic flow. On the expressway, especially under severe weather conditions such as snow and fog, once accidents such as collision, reverse travel, high-speed breakdown, rollover, and fire occur, a series of subsequent accidents will occur, and the losses caused are difficult to estimate. [0003] Aiming at the characteristics of expressway driving, in order to improve the safety of expressway driving, a patent with application number 201120182142.6 and authorized announce...

AI Technical Summary

Problems solved by technology

However, when the car is running at high speed, GPS, Beidou satellite navigation system, 2G, 3G, Zigbee and other wireless transmission systems have the problems of slow communication speed and unstable communication, which cannot realize the fatigue driving reminder and anti-rear collision reminder proposed in the patent. , car distance reminder and other functions

At the same time, the current expressway pass card in my country has a single function, does not have real-time communication, security protection and other functions, and does not match the increasingly developed expressway network
