全自动运行的地铁信号故障高效恢复设计及其高可用性

Design for Efficient Failure Recovery and High Availability of Fully Automatic Operation in Metro Transit Systems

CBTC(基于通信的列车控制)是城市轨道交通领域最先进的信号技术,能够实现不同等级的列车自动化,并保证列车的安全运行。全自动运行(FAO)CBTC系统能够实现最高等级的列车自动运行。然而,在FAO下列车上没有司机,因此故障的发生成为运营方最为关切的问题。泰雷兹FAO CBTC系统中所采用的技术可以将故障对列车运行的影响最小化,能够实现高可用性,并使中央操作人员远程管理列车与轨旁设备的某些故障。此外,智能传感器与自动驾驶领域的新技术为FAO CBTC系统带来了新的发展,使其具备自动故障恢复和意外事件管理的能力。

CBTC signaling is considered as the most advanced technology in urban rail transit domain,it can offer different automation grades and ensure safety of train operations. The CBTC FAO system offers the maximum automation of train operation and is popular in modern urban rail transit signaling domain. However,automation failures are significant operation concerns because there is no driver on a FAO train.It is feasible to minimize the operational failure impacts in a CBTC FAO system,which is illustrated by the techniques used in Thales CBTC FAO systems to provide high availability for central operators in remote management of trains and trackside device failures. At the same time,new technologies in smart sensor and autonomous vehicle operation domains may lead to development of new solutions for FAO signaling system,raising intelligence for autonomous failure recovery and unexpected event management.
