浅谈CBTC信号系统后备模式的分类及应用

Discussion on Classification and Application of CBTC Signal System in Stand-by Mode

目前在建及拟建的城轨交通项目中,信号系统绝大多数采用基于通信的移动闭塞列车控制(CBTC)系统,且大部分城市的CBTC系统都考虑了适当的后备模式。介绍国内城轨交通CBTC信号系统不同后备模式的设备配置、工作原理、系统性能等,以便进一步阐述CBTC信号系统后备模式的分类及应用情况。

Signaling systems based on moving block train traffic control system, for short, CBTC, are a dopted in most of the urban rail transit projects currently under construction or being proposed and appro priate back-up mode have been taken into consideration for the CBTC systems in most cities. This article introduces the device configuration, working principle, and system performance of different back-up modes of the CBTC signaling systems of domestic urban rail transit and elaborates the classification of back-up modes of CBTC signaling systems and their apphcations
