Problems solved by technology

However, under the background of increasing pressure on network security, the direct access of the main machine of the self-discipline machine to the storage medium of the backup machine is very easy to be intercepted by the security monitoring equipment, resulting in the failure of the synchronization operation
In addition, the performance of read and write operations of third-party storage media is seriously behind the performance of data memory operations, which hinders the synchronization efficiency of the master and backup of the self-discipline machine

Embodiment Construction

[0027] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0028] The embodiment of the present invention provides a high-speed railway dispatching centralized autonomous machine system for real-time synchronization of primary and backup data. Among the two sets of autonomous machine equipment, the module with the smaller IP address is the A machine, and the other is the B machine. At the same time, the A / B machine has only one set of modules as the main machine, and the other set is the standby machine. T...

Abstract

The invention discloses a high-speed railway dispatching centralized autonomous machine system capable of synchronizing main and standby data in real time, which realizes seamless transition of service logic in the main and standby switching process of an autonomous machine through overall synchronization of main and standby timing of the autonomous machine to assist real-time incremental synchronization, and ensures the integrity, consistency, uniformity and continuity of the service logic of the autonomous machine. Finally, stable, reliable and continuous operation of core functions of the driving scheduling system is realized, and high-speed rail driving safety is guaranteed.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a high-speed railway dispatching centralized autonomous machine system for real-time synchronization of master and backup data. Background technique [0002] The high-speed railway dispatching system is the command center for the daily organization of railway transportation. The autonomous machine system deployed at the station generates traffic instructions within the jurisdiction according to the stage plan laid out by the dispatching center, and generates traffic instructions in the station objects such as lanes, intervals, switches, and various signals, as well as the routes represented by the combination of these objects. Under the control of state change drive and instruction trigger timing, internal business logic and security card control operations are executed in an orderly and reliable manner. As the core unit of the train dispatching system, the stable operation...
