Abstract: In the case of virtual coupling without actual physical connection, multiple trains can form a logical unit virtually coupled through cooperative control to realize joint train control and dispatching. Based on the traditional CBTC system, this paper introduces the virtual coupling application in the CBTC system, and analyzes key technologies and the architecture of CBTC system using virtual coupling. The virtual coupling application in the CBTC system makes the operation more flexible and can greatly shorten the train operation interval. The research of virtual coupling provides ideas and references for future train control system.

摘要： 虚拟编组在无实际物理连接的情况下，通过协同控制使多个列车形成一个虚拟耦合的逻辑整体，共同实现大编组列车运营组织。基于传统CBTC系统提出虚拟编组CBTC系统方案，并对虚拟编组CBTC系统方案的系统结构以及关键技术进行分析。该虚拟编组CBTC系统方案使运营更加灵活，能够极大地缩短列车运行间隔，为未来轨道交通的列控系统研究提供思路和参考。
