Subway vehicle electronic record system based on blockchain technology

A subway vehicle electronic record system based on blockchain technology, comprising includes:

• at least one processor;
• and
• a memory storing instructions that, when executed by the at least one processor, implement:
• a business view module which allows users with different functions to access a record information view comprising a user interface;
• a record information maintenance module, which is used to add, modify and search data information about subway vehicle records according to different stages and different functions as well as allow personnel of responsible departments to access the maintenance function for the vehicle record information, wherein the “stages” refers to procurement, operation, renewal and reconstruction, and the “functions” refers to maintenance, repair and assets;
• a statistical analysis module, in which the vehicle information could be searched, sorted out and analyzed from different management dimensions, for data statistical analysis related to a vehicle, which could be displayed in tables and charts;
• a record information management module, which is for the management and maintenance of subway vehicle basic information, parts, data collection, suppliers and data security;
• wherein the “subway vehicle basic information” includes subway vehicle models, subway vehicle configuration, and subway vehicle grouping;
• a system management module, which is for the management of organizational system, personnel, system roles, authority and log monitoring;
• and
• a blockchain foundation platform, which is for the visual deployment, upgrading, and updating of smart contracts, as well as the uploading of the record data to a blockchain and storage and verification of record data;
• wherein the smart contracts on the blockchain comprise basic function contracts, the basic function contracts aiming to manage and control the permission scheme on each node in the blockchain, and including a blockchain access control contract, a digital identity management contract, and a data privacy protection contract;
• wherein the blockchain access control contract realizes platform resources, authority, roles, and authentication on the chain;
• wherein the digital identity management contract realizes mutual mapping between user identity and digital identity;
• and
• wherein the data privacy protection contract provides on-chain data privacy rule settings and data encryption authorization at a multi-identity level.
