摘要
对轨道交通系统中信号系统的升级需求进行了分析,归纳了系统升级中应考虑的几个问题。以英国伦敦维多利亚线信号系统升级项目为实例,分别从过渡设备的安装、车辆测试、信号系统更新、控制中心升级等方面介绍了基于通信的列车控制技术的应用及其关键技术。
Communication based train control（CBTC） technology, with its advanced communication and computing management, breaks through the limitation of fixed block control. This paper briefly introduces the CBTC technology, its advantages in technology and low cost compared to the tradition signal system, discusses the problems in the upgrading of UMT signal system, the application of CBTC and the critical techniques in the upgrading projects.
