Vehicle-road collaborative data interactive system by means of multi-mode wireless communication

Abstract

The invention discloses a vehicle-road collaborative data interactive system by means of multi-mode wireless communication, which belongs to the field of intelligent transportation, comprises road testing equipment, central equipment, vehicular equipment and hand-held terminal equipment, and is operated in a Windows operation system environment. The vehicle-road collaborative data interactive system has the advantages that 1) realizing data interaction among transportation participants; 2) meeting diversified demands of the transportation participants on transportation communication; 3) integrating various information interactive modes in various vehicle-road collaborative systems including vehicle-vehicle/vehicle-road communication; 4) reliability and soundness of a vehicle-road collaborative communication network are effectively guaranteed by communication control, and the problems of topology high-speed transformation, communication barrier and the like are effectively adapted to; and 5) safety and reliability of data are guaranteed by means of AES (advanced encryption standard) encryption and CRC (cyclic redundancy check) data check, external attack is eliminated, and data loss in wireless transmission is detected.

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 info
