印度新孟买地铁1号线车辆自动过分相系统设计

Design of automatic control neutral-section passing system of navi mumbai metro rail project line-1

介绍了印度新孟买地铁1号线车辆(NMML1)自动过分相系统的设计。该项目和国内大多数项目不同的是:地面传感器的供货和安装由车辆供应方负责,因此需要计算地面传感器的安装位置,以便于施工人员安装地面传感器。模拟分析车载信号接收器失效情况,主要是为了验证在自动过分相系统失效的情况下,司机根据“分”“合”主断路器的指示牌进行手动过分相也能满足车辆运行要求。计算过分相的最低运行速度则是为了保证列车能在各种极限工况下都能安全有效地通过分相区,后续将在车辆实际运营后,对有效通过分相区的最低速度以及地面传感器的设置进行验证。

This paper chiefly introduced the design of automatic control neutral-section passing system of Navi Mumbai Metro Rail Project Line-1(NMML1),including the working principles,introduction of system composition,calculation of installing position of ground sensor,simulation analysis when onboard inductive receivers lose efficacy.The calculation of lowest running speed when metro passing through the neutral section effectively under all kinds of running conditions.
