摘　　要：根据轨道交通信号控制系统在物理上的分布特性和物理-信息的紧密性,提出了一种信息在物理融合系统(Cyber-Physical System,CPS)环境下的分布式轨道交通信号控制系统,并分析CPS在轨道交通控制领域的优势。对在该环境下的CPS结构体系进行了模块划分和构架,提出了将轨道交通控制设备划分为不同类型的三层架构节点:自治层、信息层和协同层。基于轨道交通安全基本条件划分了三大类安全控制功能,最后通过这三类安全控制功能设计了各节点之间的协同机制及协同控制过程。阐明了将CPS运用于分布式轨道交通控制系统中可产生可拓展性、灵活性和鲁棒性上的优势。According to the physical distribution characteristics and the tightness of physical-information in railway signal control system,a system of distributed railway signal control in CPS is proposed,the advantages of CPS in railway control are analyzed.Then,the module division and structure in CPS environment are given,in which the rail traffic control equipment is divided into three-layer nodes:autonomous layer,information layer and cooperative layer,their safety control functions are summarized based on railway safety conditions.Finally,the cooperative control process of each node is designed by using the three types of safety control functions,the advantages of the CPS distributed control system in producing scalability,flexibility and robustness are illustrated.
