High-speed charging method and system based on block chain

Abstract

The invention discloses a high-speed charging method and system based on a block chain, and the method comprises the steps: S100, obtaining the vehicle information of a vehicle when the vehicle passesthrough an entrance of a toll station, generating first transaction flow data, and uploading the first transaction flow data to a road section center to which the toll station belongs; s200, when thevehicle passes through the ETC portal frame, acquiring and uploading path information and cost information of the vehicle to a road section center to which the ETC portal frame belongs; and S300, when the vehicle passes through an exit of the toll station, acquiring path information and cost information of the vehicle and uploading the information to a road section center to which the toll station belongs. The block chain technology and the high-speed CPC charging technology are combined, distributed storage of data is achieved, the data security level is improved, data loss and illegal tampering are prevented, point-to-point data transmission of the center of a road section is achieved, the path backtracking speed is increased, and the path query network pressure is reduced.

Description

technical field [0001] The invention relates to the field of intelligent transportation, in particular to a blockchain-based high-speed billing method and system. Background technique [0002] At present, the overall structure of the national expressway network toll collection system consists of the toll road network settlement management center (hereinafter referred to as the "ministry network center"), the provincial (district, city) network settlement management center (hereinafter referred to as the "provincial network center"), and the road sections in the province. Center, toll station, ETC gantry system, etc. Based on 5.8G DSRC technology, the OBU vehicle "segment billing, segment toll" is realized in the state of free flow of vehicles, and the vehicle equipped with CPC calculates the charges of different road sections according to the polysemous path method, and collects them uniformly at the exit. Vehicle information is stored in the provincial networking center an...

AI Technical Summary

Problems solved by technology

Vehicle information is stored in the provincial networking center and the departmental networking center. Centralized storage may lead to slow query information, increase vehicle transit time, prone to data loss and tampering, and difficulty in tracing vehicle routes.
