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OA北大核心

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.
