Multi-mode wireless communication vehicle road cooperation data interaction system

Abstract

The invention discloses a multi-mode wireless communication vehicle road cooperation data interaction system which belongs to the intelligent traffic field. The system is formed by road test equipment, center equipment, vehicle equipment and hand-held terminal equipment and is operated under a Linux operating system environment. The system of the invention has the following advantages: 1) Realizing data interaction between traffic participants; 2) Satisfying a diversification demand of the traffic participants to traffic communication; 3) Integrating a plurality of information interaction modes in a plurality of vehicle road cooperation system, such as vehicle to vehicle / vehicle-road communication and the like; 4) Using communication control to effectively guarantee reliability and soundness of a vehicle road cooperation communication network and effectively adapt problems of topological high-speed transformation, a communication barrier and the like; 5) Using a mode comprising AES encryption and CRC data verification to guarantee security and reliability of data, eliminating a foreign attack and detecting data loss in wireless transmission.

Description

technical field [0001] The present invention relates to the field of intelligent transportation, in particular to a multi-mode wireless communication vehicle-road coordination data interaction system, which provides motor vehicle drivers, pedestrians and traffic managers and travelers in urban road traffic that can be used to improve traffic safety and traffic Efficient data interaction platform. Background technique [0002] With the continuous increase of traffic accidents and traffic congestion, a large number of traffic control and traffic guidance facilities have been applied to the actual road traffic system. The data basis for its normal operation is various types of traffic sensors, but the traffic data collected by these sensors are often only Compared with the whole city, it is only partial traffic data from floating cars, some intersections and a small number of road sections. These data are often incomplete for traffic control and traffic guidance, resulting in t...

Problems solved by technology

[0005] In order to solve the defects in the autonomous safety protection of vehicles and the cross-section collection of traffic information in the prior art: the vehicle cannot carry out coordinated safety protection according to the operating conditions of surrounding vehicles, but only relies on the sensors carried by the vehicle itself and the safety awareness of the driver and response for autonomous safety protection; the traffic control and guidance system cannot obtain overall traffic information, but can only rely on incomplete traffic information in local areas to implement traffic control strategies and issue guidance information; the present invention provides a multi-mode The wireless communication vehicle-road coordination data interaction system, with the help of advanced multi-mode wireless communication technology, realizes real-time, reliable and large-capacity data interaction among traffic participants including vehicles, roadside equipment, pedestrians and centers, so as to further improve urban Provide data support for road traffic efficiency and traffic safety conditions
