以列车为中心自主控制系统研究

Research on Train-centric Autonomous Control System

随着城市化的迅速发展,对列车运行速度和密度的要求不断增加,传统的地面控制中心控制范式受到系统架构的限制,已不能满足新需求,逐渐演变为以列车为中心的控制架构。与基于通信的列车控制系统相比,以列车为中心自主系统架构的改变带来了控制逻辑、功能、设备和接口等方面的变革。通过对车车通信和控制、资源管理和环境状态感知3个新增核心功能和关键技术进行分析,新系统控制信息流链路更加紧凑,简化了道岔区间的控制逻辑,提升了系统的运行性能。系统架构突破了以前的规模限制,引入虚拟连挂和虚拟编队等多种业态,提高了系统的可靠性;此外,系统的拓展性也得到了增强,有利于进行系统改造;在系统故障时,可以实现无人化和远程处理,在增加系统可靠性的同时减少了人工操作的需求。

With the rapid development of urbanization,the demands for train operation speed and density are continuously increasing.The traditional ground control center control paradigm is constrained by system architecture and can no longer meet new requirements,gradually evolving into a train-centric control architecture.Compared to communication-based train control systems,the shift to a train-centric autonomous system architecture brings about changes in control logic,functions,equipment and interfaces.By analyzing three new core functions and key technologies in train-to-train communication and control,resource management,and environmental state awareness,the new system streamlines control information flow links,simplifies control logic in track sections,and enhanced system performance.The system architecture breaks through previous scale limitations,introducing various formats such as virtual coupling and virtual convoy,thus improving system reliability.Furthermore,system scalability is also enhanced,facilitating system upgrades.In the event of system failures,unmanned and remote handling can be achieved,increasing system reliability while reducing the need for manual operations.
