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.
