信号系统提升车站折返能力的研究

影响城市轨道交通通过能力的关键因素是折返站的折返间隔,提高车站折返间隔可采用合理配置车站配线、优化信号系统控制、优化车辆性能、压缩停站时间等措施。文章从分析典型站折返的作业项目和作业时间入手,提出影响折返间隔的因素和优化措施;并重点从优化信号系统控制的角度,根据联锁进路控制原理、列车控制原理,提出通过联锁设计、ATP设计、ATO设计以及设备选型来提高折返站折返能力的方法。

Study of Improving Turn-back Capability of Turn-back Station through Signal System

The key factor affecting the passing capacity of urban rail transit is the turn-back interval of the turn-back station.To improve the turn-back interval of the station,measures such as proper allocation of station track layout,optimized control of signal system,improvement of vehicle performance,and cut-down of stop time can be adopted.Starting with an analysis of the operation jobs and operation time of the turn-back for a typical station,the factors influencing the turn-back interval are analyzed and some optimization measures are put forward.For the purpose of optimizing the control of signal system,the method of improving the turn-back capability of a turn-back station through interlocking design,ATP design,ATO design and equipment selection according to the interlocking route control principle and train control principle is found out.
