Vehicle maintenance information processing method and system based on block chain

Abstract

The invention provides a block chain-based vehicle maintenance information processing method and system, and the method comprises the steps: obtaining maintenance data of a target vehicle through a data collection module, the maintenance data comprising fault data, vehicle attribute data and a maintenance record; the data verification module verifies the vehicle attribute data and the maintenance record to obtain a first verification result; when the first verification result meets a preset first verification condition, the block chain network module encrypts the fault data and the maintenance record according to the vehicle attribute data to obtain first encrypted data, and broadcasts the first encrypted data to a query sharing module; after the query sharing module receives the first encrypted data, the block chain network module analyzes the first encrypted data to obtain first analyzed data; and the query sharing module determines query sharing data corresponding to the first analysis data according to the query sharing request and shares the query sharing data. Therefore, the credibility and the sharing degree of the vehicle maintenance information can be improved.
