A blockchain-based train diagram generation system and method

Abstract

Embodiments of the present invention provide a system and method for generating train diagrams based on blockchain. The system includes subsystems of a preset type of CBTC system, and a blockchain composed of blockchain nodes set in each subsystem based on a consensus mechanism; the subsystem is used to update trigger conditions according to train passenger information and operation diagrams, Send an instruction to update the operation diagram to the blockchain node; the blockchain node is used to generate blockchain transactions, execute the pre-stored smart contract to update the operation diagram information, and broadcast to other blockchain nodes. The selected subsystems of the CBTC system set up the corresponding blockchain nodes and combine them into a blockchain. According to the operating diagram update instructions issued by the subsystems and the smart contracts pre-stored by the blockchain nodes, new operating diagram information is generated, and Send it to each blockchain node, so that the operation graph information can be efficiently updated to adapt to the current operating environment of each subsystem in real time.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a system and method for generating train diagrams based on block chains. Background technique [0002] In the CBTC (Communication Based Train Control System) system (communication-based train operation control system), the operation diagram generation method based on the traditional compilation method is mainly to optimize the train operation plan, solve the train operation plan by time period, and finally obtain Train operation diagram with fixed departure intervals by time period. [0003] The traditional compilation method is mainly manual compilation. Before starting the map compilation work, it is necessary to manually search for line operation data, line operation diagram compilation restrictions, and transfer data. During the map compilation process, it is necessary to manually check the return conditions, Manual statistics of technical index parameters and manual in...

AI Technical Summary

Problems solved by technology

[0004] The preparation method based on manual compilation makes the formation process of the operation diagram excessively dependent on manual operation, and the preparation of the operation diagram takes a long time, and it is impossible to adjust the train operation plan in real time according to the change of passenger flow and energy consumption indicators
