摘要
接近锁闭是保障铁路行车安全的一种作业方式。对于不同速度等级的列车,现有接近锁闭方法将接近区段的长度统一设置为固定值,忽略了列控等级、车速和制动性能的差异,造成车站资源的过度占用,影响车站的通过能力。本研究从接近区段长度的计算方法以及自动排路触发时机与接近区段的关系入手,以列车牵引计算和高速铁路进路办理流程为关键因素,提出一种可变接近锁闭方法。通过在列车和车站增设必要的硬件设备实现车站根据列车状态信息动态设置接近锁闭区段长度和触发办理进路时机的功能。最后,以某车站为例进行仿真实验,实验结果表明采用可变接近锁闭方法能有效提高车站通过能力,采用可变接近锁闭方法后咽喉区通过能力最大提高85列,到发线通过能力最大提高32列。
Approach locking is a way to ensure railway operation safety.For the trains with different speed levels,the existing approach locking methods uniformly set the approach section length as a fixed value,which ignores the differences in the train control levels,speeds,and braking performance to cause excessive occupation of station resources and affect the station passing capacity.Based on the calculation methods of approach locking sections and the relationship between trigger time for automatic routing and approach sections,this paper proposed a variable approach locking method by considering train traction calculation and routing handling process of high speed railway as key factors.This method added necessary hardware equipment to make the station set the approach locking length and trigger routing handling time according to the train status information.Simulation experiments conducted by taking a station as an example show that the proposed method can improve the station passing capacity,and increase the passing capacity of the throat area by up to 85 trains and the passing capacity of the arrival-departure track by up to 32 trains.
