Abstract

The invention belongs to the technical field of Internet of Vehicles data transmission, and discloses a distributed Internet of Vehicles data transmission system and method based on a blockchain technology, the distributed Internet of Vehicles data transmission method based on the blockchain technology comprises the following steps that: a data acquisition module acquires channel related information; a positioning module carries out real-time positioning on a vehicle; a data request sending module sends required data keywords by utilizing input equipment; a data processing module is used for processing and classifying the acquired data based on a plurality of node blockchains according to the area in the charge of each node blockchain; a database uses a plurality of distributed databases corresponding to the node blockchains to store data of each area; an abnormality determination module determines whether the vehicle is abnormal or not; a map updating module is used for updating and perfecting a conventional map; a road condition information summarizing module is used for extracting and summarizing road condition data; a navigation module is used for path planning. According to the invention, various information such as weather, positioning, vehicles, road conditions and the like can be collected and networked for sharing.

Description

technical field [0001] The invention belongs to the technical field of vehicle networking data transmission, and in particular relates to a distributed vehicle networking data transmission system and method based on block chain technology. Background technique [0002] At present, as cars become more and more popular, the types and functions of on-board equipment are also increasing, including navigation, monitoring, anti-theft and multimedia entertainment. Existing vehicle-mounted devices operate independently and need to use related mobile terminals. Each device is independent of each other and cannot communicate with each other. Each vehicle also exists independently and cannot share data. Therefore, there is an urgent need for a new data transmission method for the Internet of Vehicles. [0003] Through the above analysis, the existing problems and defects of the existing technology are: the existing Internet of Vehicles data technology is all about uploading data infor...
