适应四网融合的市域(郊)铁路列控系统互联互通设计方案研究

Research on Design Scheme of Interconnection and Interoperability of Regional(Suburban)Railway Train Control System in Response to the Integration of the Four Networks

近年来,“四网融合”发展已成为国家对轨道交通发展的重大战略,信号系统互联互通是实现“四网融合”的关键条件。从信号系统应用情况看,近期市域(郊)铁路信号系统列控制式大多数采用CTCS2+ATO,城市轨道交通线路信号系统主要采用CBTC,有必要对这两种列控系统互联互通设计方案进行研究。依托实际工程应用需求,采用重点内容举例和类比分析方法。首先,分析了互联互通土建及设备系统需要具备的工程条件,并对两种典型列控系统情况进行说明;之后,结合国内互联互通线路接驳及车站配线工程需求,阐述互联互通主要设计原则、制式转换最关键的共管区设计要点,以举例分析方式对停车和不停车切换的典型运营场景进行说明;最后,根据不同的设备设置方式,从调度指挥、车载列控和联锁设备几个方面,提出了完全独立和完全融合两种系统互联互通的建议方案;系统阐述互联互通需要具备的工程条件、共管区结合列控系统统一布置的设计要点,按两套车载设备同时在线和作业流程研究典型运营场景,提出了完全独立和完全融合两种方案的调度信息处理、车辆接口方式和联锁处理策略。

In recent years,the development of“Four-network Integration”has become a major strategy for the country railway transportation development.Interoperability of signal systems is a key condition for achieving“Four-network Integration”.Based on the application of signal systems,the majority of urban and suburban railway signal systems currently use CTCS2+ATO,while urban rail transit line signal systems mainly adopt CBTC.Therefore,it is necessary to study the design schemes for the interconnection of these two train control systems.Relying on the actual engineering application requirements,we will use examples and analogy analysis methods,focusing on key contents.Firstly,we analyze the engineering conditions that need to be met by the interoperable civil and equipment systems,and explain the typical train control system scenarios.Then,combining with the domestic interconnection line connection and station distribution engineering requirements,we elaborate on the main design principles and key points of co-management area design for system conversion.We also illustrate typical operational scenarios of stop and non-stop switching through case analysis.Finally,according to different equipment setup methods,we propose two recommended interoperability schemes:completely independent and completely integrated systems.We systematically describe the engineering conditions required for interoperability and the key design points of co-management area combined with train control system layout.We also study typical operational scenarios based on the simultaneous online operation of two sets of onboard equipment and work processes.The dispatch information processing,vehicle interface mode,and interlocking handling strategies are proposed for both completely independent and completely integrated schemes.
