Research on High-speed Railway Train Operation Simulation System

为辅助解决铁路运营中不同层次的规划和设计问题,进一步提高高速铁路运营精细化管理水平,有必要构建高速铁路行车仿真系统。在阐述国内外铁路行车仿真系统研究现状的基础上,确定高速铁路行车仿真系统的整体框架,并采用时间驱动机制描述行车仿真的工作流程,重点分析铁路行车仿真系统中复杂度最高的调度系统与列车运行控制2个核心模块,最后通过计算京沪高速铁路曲阜东—滕州东区段列车最小追踪间隔时间,对仿真系统进行功能验证。结果表明,该系统能为铁路相关单位提供试验设计、线路规划、运营模拟、调度优化等方面的技术和平台支撑。

In order to solve different-level planning and design problems in railway operation, and further improve the management of high-speed railway operations, it is necessary to build a high-speed railway operation simulation system. On the basis of expounding the study status of the system in China and other countries, the overall system framework is determined. This paper describes the working process of train operation simulation by time-driven, and focuses on the analysis of 2 core modules（traffic control system and train operation control system）, which are the most complicated in railway train operation simulation system. In the end, through calculating the minimum train headway time from Qufu East Station to Tengzhou East Station on Beijing-Shanghai high-speed railway, the simulation system＇s function is verified. The study result shows that the system could provide technical and platform supports for railway-related departments from the aspects, such as test and design, line planning, operation simulation, and traffic control optimization.
