Problems solved by technology

[0003] However, during the joint exercise of the multi-work and remote distributed simulation training system for railways across networks and distances, there is data out-of-sync when the modules in different regions communicate, which leads to inaccurate system simulation results; in addition, the star network structure of the railway private network The unreasonable setting of the location of the simulation server in the middle reduces the simulation speed to a certain extent

Abstract

The invention discloses a distributed simulation method and system for railway multi-work types based on cross-network and cross-distance, and relates to the field of railway simulation training. The server completes the core computing tasks of the training clients corresponding to each type of work; through the synchronization manager, statistically manages the dependencies representing the core computing processes in each training client, and triggers and controls the training clients in order to perform simulation model calculations according to the dependencies. After the training client finishes sending data, perform time stamp registration, and after completing all time stamp registrations within the synchronization period, perform synchronization point registration update. The invention can realize data interaction and synchronization in the joint exercise process of cross-network and cross-distance training subsystems, and ensure that the simulation speed meets the real-time requirement without adding additional hardware devices, and has good application prospects.

Description

technical field [0001] The invention relates to the field of railway simulation training, more specifically, it relates to a distributed simulation method and system for railway multi-work types based on cross-network and cross-distance. Background technique [0002] The large-scale construction and operation of railways has made the training needs of railway employees continue to increase, and the railway multi-job joint simulation training system came into being. Railway multi-type joint simulation training systems are often distributed in different regions and have the characteristics of spanning distances. At the same time, each module of the system in the same area communicates through the internal LAN, and each module in different areas relies on the railway private network to connect to a star network structure for communication, so it also has the characteristics of cross-network. [0003] However, during the joint exercise of the distributed simulation training sys...
