大坡道线路条件下信号系统适应性设计及ATO节能的策略

Adaptability Design of Signal System and ATO Energy Saving Strategy in Line Condition with Long Steep Grades

在山地城市轨道交通工程的建设中,长大坡道已是常见的线路条件。信号系统是城市轨道交通中安全相关的系统,针对长大坡道线路条件需要提出适应性设计的措施。结合贵阳市轨道交通2号线工程案例,提出信号系统设计为适应长大坡道线路的几个关键策略,同时对ATO的节能方案进行研究,为类似线路条件下的信号系统方案提供设计参考。

In mountainous regions, urban rail transit projects are usually m me nne condition with long steep grades. As a safety related system, the signal system should be especially designed suitable to the long steep grade line condition. The paper puts forward several key strategies of signal system design and ATO energy saving strategies that adapt to long steep grade line conditions combining with actual case of implementing Guiyang metro line 2, hopefully providing reference for the similar cases in other projects.
