Vehicle road real-time communication system and communication method based on cellular network

Abstract

The invention relates to a vehicle road real-time communication system and communication method based on a cellular network. The vehicle road real-time communication system based on a cellular networkincludes a vehicle-mounted-end communication component, and a central platform, wherein the vehicle-mounted-end communication component is used for acquiring vehicle information and motion parametersfrom a vehicle-mounted client in real time, transmitting the vehicle information and the motion parameters to the central platform, and performing information verification and delay correction on thecontrol signal data; and the central platform is used for receiving the location information data sent by the vehicle-mounted-end communication component to perform analysis, association and matchingon the location information data, and sending the control signal data to the vehicle mounted-end communication component. Compared with the prior art, the vehicle road real-time communication systembased on a cellular network has the advantages of being flexible in system deployment, being safe and controllable, being simple in development and maintenance, supporting independent development, being low in delay and high in reliability, being low in traffic consumption, being preferable in scalability, supporting communication technology evolution and the like.
