摘　　要：城市轨道交通延伸线的建设必然会对既有线运营产生一定影响,因此延伸线信号系统方案的选择、与既有线信号系统如何实现贯通等成为影响延伸线项目开通运营的关键因素。结合青岛地铁2号线既有线和延伸线的实际情况,对比延伸线采用与既有线相同信号系统和采用自主化信号系统2种方案,确定延伸线采用自主化信号系统方案,并阐述其架构和优势。从共用控制中心、软件升级、硬件改造、延伸线测试及调试等方面详细阐述与既有线互联互通的方案,并针对系统差异提出应对措施。为城市轨道交通类似的分段开通线路的信号系统延伸线项目,在不中断既有线正常运营的前提下,实现延伸线与既有线贯通运营的目标,提供信号系统设计方案的技术参考。The construction of the extension line of an urban rail transit will inevitably have a certain impact on the operation of the existing line.The selection of the signal system of the extension line and how to connect the signal system of the extension line with that of the existing line become the key factors affecting the opening and operation of the extension line.Based on the actual situation of the existing line and the extension line of Qingdao Metro Line 2,two schemes of the signal system for the extension line,one scheme adopting the same type of signal system of the existing line and the other adopting domestic signal system,are compared.And it is determined that domestic signal system is adopted for the extension line and the architecture and the advantages of the domestic signal system are described.The connectivity and inter-operation solution to the signal system of the extension line with that of the existing line is discussed,including sharing control center,software upgrading,hardware transformation,as well as testing and commissioning of the signal system of the extension line.Responding measures are also presented to cope with their discrepancies.For similar extension line project of a segmented opening in urban rail transit,this article can provide technical reference for the design scheme of the signal system to attain the goal of connecting the signal system of the extension line to that of the existing line without interrupting the normal operation of the existing line.
