高普速场互联互通时场联及列控系统方案研究

客运专线高速场与既有线普速场并站互联互通的情况在实际工程应用中越来越多,此时两场间联络线信号机设置情况及普速场列控、联锁设置方案比较复杂。以张呼铁路呼和浩特东站(含高、普速场)为例,详细分析普速场联锁及列控设置的最佳方案,并根据联络线长短分别给出高、普速场间联络线信号机设置最优方案:联络线较短时,因无法设置信号机,可由普速场集中控制该组双动道岔,经过道岔反位的进路,采取在各自的联锁区先后分段办理进路的方式;联络线较长时,需要结合安全、方便操作及节省投资等因素综合考虑,推荐在联络线处设虚拟列车信号机的方案,办理列车接发车进路时,同样需采用两联锁区两段进路分段办理方式。上述推荐方案可实现高、普速场跨场接发普速车及动车组的运营需求。

Research on Liaison between Yards and Train Control System in Interconnection of High-speed and Conventional Speed Railway

Taking Hohhot East Station(including yards of both high-speed railway and conventional railway)of Zhangjiakou-Hohhot railway as an example,the paper analyzes the optimal scheme for setting the interlocking and train control systems for the conventional railway,and presents the scheme of setting signals for the liaison line between yards of the high-speed railway and conventional railway according to the length of the liaison line.When the line is too short to set a signal,crossover turnouts will be controlled with double-working switches in conventional yards,meanwhile,the train receiving/departure routes through the turnouts in reverse position will be set in two interlocking sections separately.When the liaison line is long,it needs to be considered in combination with factors such as safety,convenient operation,and investment saving.This article recommends the scheme of setting up a virtual train signal at the liaison line.When handling the train receiving-departure route,sectional route handling is also needed in the two interlocking areas.The recommended scheme can meet the operation requirements of receiving-departure trains and EMUs between high-speed and conventional yards.
