CBTC系统在车站保护区段的解锁优化方案

在基于通信的列车控制系统(CBTC)中,保护区段的设置在保障列车安全停车、提高运营效率方面有着重要的作用。为此,在分析保护区段CBTC功能实现及解锁方式的基础上,基于项目实际经验,设计了保护区段解锁的触发区段,以及增加站台区域点式列车自动防护模式下车载设备与联锁设备间无线通信接口的优化方案,以实现保护区段解锁的优化。

Optimum Scheme of Overlap Releasing in Urban Rail Transit CBTC System

In CBTC,the overlap design plays a very important role in the guarantee of train safety stopping and the operation efficiency improvement. Based on an analysis of overlap func-tion and releasing strategy,an optimum scheme of overlap re-leasing triggering section is designed according to the experi-ences of practical project,the radio interface between spot transmission ATP on-board equipment and interlocking equip-ment in station region is added,aiming to implement the over-lap releasing optimization.
