Internet of Vehicles communication method and system

Abstract

The embodiment of the invention provides an Internet of Vehicles communication method and system, and the system comprises a vehicle-mounted communication terminal and a cloud platform which are installed in an intelligent vehicle, and the vehicle-mounted communication terminal transmits an uplink message to the cloud platform. The uplink message comprises a first message type identifier, a firstrequest identifier, a first message matching field, a first request matching field and a first service message; the cloud platform analyzes the uplink information message, and sends a downlink response message to the intelligent network connection vehicle when the first message type identifier is a request confirmation identifier, wherein the downlink response message comprises a confirmation identifier corresponding to the request confirmation identifier, a first response identifier corresponding to the first request identifier, a message matching field which is the same as the first messagematching field and a request matching field which is the same as the first request matching field. And a perfect and reliable request response matching mode in Internet of Vehicles communication is provided.

Description

technical field [0001] The present invention relates to the technical field of the Internet of Things, in particular to a communication method and system for the Internet of Vehicles. Background technique [0002] With the continuous development of information technology, there are more and more applications of the Internet of Things, among which the Internet of Vehicles is an important application scenario of the Internet of Things. [0003] In the Internet of Vehicles system, a vehicle-mounted communication terminal is installed on the vehicle, and wireless networking is realized through a SIM card. The vehicle-mounted communication terminal acts as a gateway for the vehicle to access the Internet, and realizes the collection, buffering and forwarding of vehicle-related data. Correspondingly, the cloud server in the Internet of Vehicles system is responsible for storing and processing the data sent by the vehicle communication terminal, and can also send instructions to th...

Problems solved by technology

[0005] However, the MQTT protocol does not provide a request-response matching relationship, which will lead to the following two problems: On the one hand, every time the MQTT protocol is used for vehicle networking communication, the user needs to define the corresponding request-response matching method , which will cause additional workload; on the other hand, the user-defined request-response matching method may not be perfect, resulting in error-prone request-response matching
