目的:随着我国城镇化发展,城市轨道交通作为重要的交通手段,逐步呈现出多网融合、网络化发展趋势。“四网融合”发展背景下,存在跨线网互联互通运营的需求。为解决跨线网互联互通的技术壁垒,须分析研究信号系统不同制式之间的兼容解决方案。方法:介绍了CBTC(基于通信的列车控制)系统和CTCS(中国列车控制系统)的主要功能,对比分析了这2种信号系统的差异;介绍了双车载设备方案的系统总体架构,以及人工驾驶转换方案和自动过制式转换区方案的操作流程。指出从技术角度实现跨CBTC线路与CTCS线路之间的跨线运行并不存在技术壁垒,而针对管理体制以及认证模式的构建是实现“四网融合”发展的关键性因素。结果及结论:针对CBTC和CTCS兼容方案提出了双地面设备和双车载设备两种解决方案,并逐一分析其优缺点;就双车载设备解决方案展开研究,详述其人工过制式转换区和自动过制式转换区的业务流程及配套方案,分析双车载方案的优势和面临急需解决的问题。

Objective:With the development of urbanization in China,urban rail transit becomes an important transportation means,gradually demonstrating a trend of multi-network integration and networking development.In the context of′four-network integration′,there is the demand for cross-line interoperability.To address its technical barriers,it is necessary to analyze and study compatibility solution schemes among different formats of signaling systems.Method:The main functions of CBTC(communication-based train control)system and CTCS(China train control system)are introduced,and the difference between these two signaling systems is comparatively analyzed.The overall architecture of the dual on-board equipment scheme is presented,as well as the operational procedures for manual driving conversion scheme and auto-passing neutral zone scheme.It is pointed out that there are no technical barriers to achieve cross-line operation between CBTC and CTCS from the technical perspective,however the key factor for achieving′four-network integration′lies in the establishment of management systems and certification modes.Result&Conclusion:Two solutions of dual ground equipment and dual on-board equipment are proposed for CBTC and CTCS compatibility,and their advantages and disadvantages are analyzed in detail.The study on dual on-board equipment solution is carried out,providing an elaborate explanation of the business process and supporting plans for manual-passing neutral zone and auto-passing neutral zone.The advantages and urgent problems faced by the dual on-board equipment scheme are thoroughly examined.
