摘　　要：跨座式单轨作为中运量的城市轨道交通系统,它主要通过信号系统控制列车运行并同时保障列车的安全;当信号系统故障时,跨座式单轨系统的工作人员必须通过瞭望、人工准备进路组织行车,此时如果出现人员失误,会造成列车掉下轨道梁等事故,导致严重的人员伤亡。为提高跨座式单轨的安全性,根据跨座式单轨的特点设计一种道岔辅助防护系统,该系统能在信号系统故障或者失效时控制列车在安全区域停车,保证列车运行安全,从而降低人为操作失误带来的行车风险。As a medium volume urban rail transit system,straddle-monorail mainly controls train operation and meanwhile guarantees the safety of a train by signalling system.When the signalling system fails,the staff s of straddle-monorail system must organize train operation through lookout and manual preparing routes.At this time,even though a small human mistake will lead to a train fallling off from the track beam which will cause serious injuries and facilities.In order to improve the safety of straddle-monorail system,this paper designs a turnout auxiliary protection system considering the characteristics of straddle-monorail.This system can stop the train in the safe area in case of signalling system failure,and ensure the safety of train operation so as to reduce the operation risk caused by human operating errors.
