A communication device and control method based on the Internet of Vehicles

Abstract

The invention discloses a communication device based on the Internet of vehicles and a control method and belongs to the technical field of the vehicles. The communication device comprises a vehicle-mounted device mounted on a vehicle, an Internet of vehicles server in wireless communication connection with the vehicle-mounted device, a supplier server in wireless communication connection with the Internet of vehicles server, wherein the vehicle-mounted device communicates with the Internet of vehicles server through a TCP / IP protocol, and the Internet of vehicles server and the supplier server communicate through the TCP / IP protocol. The invention further provides a corresponding control method. According to the communication device, the TCP / IP protocol is employed to carry out communication, the communication device is reliable and simple and further has properties of low band width, low energy consumption and low cost, information transmission reliability can be effectively guaranteed, and better communication service can be provided for remote sensors and control equipment which have limited calculation capabilities and work under low band width and unreliable network environments.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a communication device and a control method based on the Internet of Vehicles. Background technique [0002] In recent years, in the technical framework of the Internet of Vehicles project, an open technical standard protocol, namely the NGTP protocol, is usually used. This agreement mainly includes three parts: the vehicle device, the dispatcher, and the service provider. The role of the effective connection between the provider's servers. When information is transmitted from the vehicle-mounted device to the supplier server, the information will first be transmitted to the dispatcher, and the dispatcher will store the information, and then transmit the information to the supplier server through the dispatcher. [0003] However, in this transmission system, the communication between the vehicle-mounted device and the dispatcher, and between the dispatcher and the supplier serv...

Problems solved by technology

[0003] However, in this transmission system, the communication between the vehicle-mounted device and the dispatcher, and between the dispatcher and the supplier server all use the HTTP seven-layer application layer protocol. Using this protocol has a large network overhead and takes up more resources, not only for the entire communication Causes a burden, and when the vehicle is in a low or unstable signal environment, it will seriously affect the quality of communication services
