摘要:
根据当前互联互通CBTC（基于通信的列车控制）系统的标准化情况、系统实施方案、延伸线和跨线的需求差异及互联互通信号系统在国内的应用情况，对比分析了延伸线路采用统一信号系统接入既有线，以及采用互联互通信号系统接入既有线在技术方案和工程实施（运营维护、安全认证、投资等）方面的差异。给出了既有信号系统互联互通标准体系用于延伸线接入时的建议方案，并得出当前互联互通信号系统在延伸线适用性结论。
Abstracts:
According to the standardization status and implementation schemeof interconnection CBTC (communication based train control) system, thedemand difference between existing line and extension line, and the application of interconnectionsignal system in China at present, the technical scheme and project implementation differences between the conventional unified signal system and the interconnection CBTC system in connecting the extension line to existing line are compared and analyzed, including operation maintenance, safety verification, investment and so on. Suggestions for applying the interconnection standard of existing signal system in connecting extension line are put forward. The conclusion of feasible applicability of interconnection signal system on extension line is obtained.
