Research on Backup Operation Solution of a Perception-based Train Control System
In urban rail transit lines using the CBTC system,when the train-ground wireless communication equipment or ground ATP equipment fails,the train usually turns to a backup operation system.The way for a train to tracking trains ahead in backup operation system determines the operating performance.It also determines the recovery time,which indicates the severity and scope of the impact on operation by the system failure.This article analyzes the shortcomings of the ITC system through a fault,and analyzes the tracking scheme based on the train active perception system,which shows that the backup operation system based on active perception can have a smaller headway on high density lines effectively,and can keep trains in service,and effectively improve the passenger service level under fault.
