摘　　要：根据城市轨道交通信号系统改造的设计原则,提出"维持既有系统制式"和"完全新建系统"2种不同的信号系统改造方案.从工程投资、工程实施,以及改造后的系统性能和运营需求等方面对2种方案进行了详细对比分析,可为信号系统的大修改造提供参考.Based on the design principle of renovating the signaling system in urban rail transit,two technical solutions for renovating the signaling system are presented:one solution to maintaining the mode of the existing system and the other solution to building a completely new system.Detailed comparison of the two technical solutions are made in considerations of project investment and project implementation as well as the performance and operational requirements of the signaling system after renovation,which can offer references for the overhaul or renovation project of the signaling system in urban rail transit.
