大连市快速轨道交通3号线调度集中系统实现方案

Implememtation of CTC System in Dalian Rapid Rail Line 3

国产化的调度集中(CTC)系统,以其完善和可靠的性能在城市轨道交通领域得到广泛应用。针对大连市快速轨道交通3号线信号CTC系统工程实例,介绍了CTC系统的体系结构、设计原理、系统功能、系统特点等。在工程实施过程中,根据大连市城市轨道交通初期客流小的特点,CTC系统的设计尽量简约,既减少了投资,又提高了性能价格比;CTC系统设计采用模块化结构,便于中、远期系统扩容;核心部件采用冗余设计,以增加系统的可靠性;所有硬件均采用国产化设备,降低了用户的维修成本;软件设计可根据用户的需求,提供灵活的解决方案。

Because of the high performance and the reliability, CTC has been applied in many urban mass transit fields. According to the transportation demands,Dalian Repid Rail Transit Line 3 signaling system, provides a set of CTC solution in detail, including system structm＇e, design principle, function, characters, etc.. The CTC was put in use in 2003 and is proved very successful.
