Abstract:
重点研究了面向列车群的运行仿真平台搭建技术。基于面向列车群的运行仿真平台需求分析，将整个系统划分为数据结构化存储与维护模块、仿真基础建模、列车运行仿真(列车牵引计算模块、车站作业仿真模块、区间运行仿真模块)、运行计划生成与优化模块、指标统计分析模块和仿真过程可视化展示模块等主要功能模块；然后搭建了面向列车群的运行仿真平台架构及数据流程；最后针对车站到发线运用核心问题构建了数学优化模型。通过上述工作，仿真平台可真实有效地实现列车群的追踪运行。该平台可进行单列车牵引计算、多列车追踪运行、列车延误及其传播特点分析、影响追踪间隔因素分析等相关技术领域。
The focus is on the construction technology of the train group-oriented operation simulation platform in this paper. Based on the demand analysis of the train group-oriented operation simulation platform, the whole system is divided into data structured storage and maintenance module, simulation basic modeling, train operation simulation (train traction calculation module, station operation simulation module, section operation simulation module), operation plan generation and optimization module, index statistical analysis module and simulation process visualization display module and other main functional modules; then build the train group-oriented operation simulation platform architecture and data flow; finally build mathematics for the core problems of the station arrival and departure line optimize the model. Through the above work, the simulation platform can truly and effectively realize the tracking operation of the train group. The platform can carry out single-train traction calculations, multi-train tracking operations, analysis of train delays and their propagation characteristics, analysis of factors affecting tracking intervals, and other related technical fields.
