[目的]随着城市轨道交通网络化发展,线网客流时空分布不均衡的特性逐渐凸显,既有列车固定编组方式难以实现“按需运输”。为充分利用线路运力,需研究新一代列车运行控制系统。[方法]提出了一种支持虚拟编组技术的列车运行控制系统设计方案,并从列车运行逻辑控制、线路资源管理及调度指挥机制等方面分析了支持虚拟编组技术的列车运行控制系统与传统列车运行控制系统的性能差异;介绍了虚拟编组的关键技术;为实现虚拟编组技术在工程项目中的应用,提出了在项目规划和设计阶段,针对虚拟编组列车停车区域、正线站台区域及站台门接口等方面需要考虑的工程设计内容。[结果及结论]车车通信架构为虚拟编组技术的实现提供了更合理的系统架构设计基础;基于“撞软墙”模型协同运行控制及智能感知的列车运行控制是虚拟编组列车运行控制系统的关键技术。随着虚拟编组技术的大规模应用,列车运行控制系统能够在客流变化时快速调整在线列车编组长度,提高了运输组织的灵活性,提升了乘客服务水平。

[Objective]With the development of urban rail transit network,the uneven temporal and spatial distribution characteristic of the network passenger flow is growing promi-nent,and it is difficult to achieve the"on-demand transporta-tion"with the existing fixed marshalling train.In order to make full use of the line capacity,it is necessary to study a new generation of train operation control system.[Method]A design scheme of train operation control system supporting vir-tual marshalling technology is proposed,and the performance difference between the train operation control system supporting virtual marshalling technology and the traditional one is ana-lyzed from aspects of train operation logic control,line re-source management and dispatching command mechanism.The key technology of virtual marshalling is introduced.In order to realize the application of virtual marshalling technology in engi-neering projects,the engineering design that needs to be con-sidered in project planning and design stage for virtual marshal-ling train parking area,main line platform area and platform door interface are proposed.[Result&Conclusion]The ve-hicle-to-vehicle communication architecture provides a more reasonable system architecture design basis for realizing virtual marshalling technology.The train operation control based on"collision soft wall"model collaborative control and intelligent perception is the key technology in virtual marshalling train op-eration control system.With the extensive application of virtual marshalling technology,train operation control system can quickly adjust the online train length when the passenger flow changes,improving the flexibility of transportation organization and the passenger service level.
