摘　　要：通过分析CBTC系统各子系统间信息流交换的信息和通信方式,简述应答器、联锁系统、ATS子系统等互联互通的制约性因素为基础设施硬件设备的统一、各子系统间传输交换信息的格式、定义及内容的统一和信息传输网络通道的畅通。简述CBTC信号系统互联互通测试与验证的工作流程及各个阶段的主要工作内容和工作重点,建议测试平台主要以验证车载系统与其他地面系统的共线及跨线运营为主,试车线测试以测试不同厂商硬件设备之间信息交互为主,针对互联互通相关线路的安全授权责任划分和授权内容提出建议;剖析郑州地铁互联互通发展的制约性因素,为后续线路建设提出建议。By analyzing the information exchange and communication methods between the subsystems of the CBTC(communication-based train control)system,the restrictive interconnection factors are improved;e.g.,transponders,interlocking systems,and ATS subsystems for infrastructure interconnectivity of conditionality factors,such as the unity of the hardware,the format of the information transmitted between each subsystem,the unification of the definition,and content and information transmission network channels.This paper briefly describes the workflow of the CBTC signal system interconnection testing and verification and the main work contents and priorities of each stage.It is recommended that the test platform is predominantly used to verify the co-line and cross-line operation of the in-vehicle and other ground systems and,the test line to test the information interaction between hardware devices with different manufacturers.Furthermore,this paper gives suggestions for the division of security authorization responsibility and authorization content for interconnectionrelated lines and analyses the restrictive factors of Zhengzhou Metro’s interconnection and development,suggesting methods for the follow-up line construction.
