一种双移动闭塞制式下的区间折返方法

An Interval Turn-back Method under Double Moving Block System Format

以上海轨道交通2号线TBTC(基于轨道电路的列车控制)系统改造为例,结合城市轨道交通TBTC及CBTC(基于通信的列车控制)系统的信号系统技术特点,介绍了一种基于区间方向控制的TBTC+CBTC双移动闭塞系统融合下的区间折返智能管理方法。其能可靠地保证列车在不同系统间自适应混合运营下的安全,同时又可有效地提高TBTC+CBTC双移动闭塞融合系统在区间混跑下的区间折返通过能力。

Taking the TBTC(track-circuit based train control)system transformation of Shanghai Rail Transit Line 2 as an example,combined with the technical characteristics of urban rail transit TBTC and CBTC(communication-based train control)signaling system,an intelligent management method of interval turn-back under TBTC+CBTC dual moving block system integration is introduced.It can reliably ensure the safety of trains during the adaptive mixed operation among different systems,while effectively improve the interval turn-back passing capacity of TBTC+CBTC dual moving block fusion system during interval mixed operation.
