CBTC与CTCS-2兼容互通方案

CBTC and CTCS-2 Compatible and Interoperable Scheme

提出“双套地面”、“双套车载”和“兼容型车载”3种解决C B T C与C T C S-2(含C T C S-2+ATO)系统之间兼容互通的可行方案,并对3种方案进行比对分析,推荐采用“兼容型车载”方案。通过“兼容型车载系统结构图”对方案的车载软、硬件配置和地面设备配置进行说明。同时,重点对切换场景进行详细描述,按不同运行方向分别对切换场景中的行车许可获得,车-地信息的交互内容,临时限速及行车许可管辖范围,切换信息的下达时机,轨旁设备的布置原则,切换失败的运行方式及对司机的操作要求等问题进行详细分析。

This paper proposes three feasible schemes to solve the compatibility and interoperability between CBTC and CTCS-2(including C2+ATO)systems:"dual trackside","dual onboard"and"compatible onboard",and compares and analyzes the three schemes,and recommends the"compatible on-board".The onboard software and hardware configuration and trackside equipment configuration of the scheme are described through the compatible onboard system structure diagram.It focuses on the detailed description of the switching scene.According to diff erent running directions,the obtaining of the movement authority(MA)in the switching scene,the onboard-trackside information interaction content,temporary speed restriction(TSR)and the MA control area,the issuing time of switching information,the arrangement principle of trackside equipment,the operation mode in switching failure,and the operational requirements for drivers,etc.are analyzed in detail.
