摘　　要：基于DX3型道口信号系统提出一种新的道口防护方法,即在列车信号开放条件中加入道口看守员确认道口防护完成以及遮断信号机状态的条件,通过道口防护完全的状态来卡控列车信号机的开放条件。当所有条件均满足时,可以实现不需要延时开放列车信号就能够实现保证平交道口行车安全的目的。同时,大大减轻交通拥堵压力,提高铁路列车和道路车辆的运输效率,提升铁路平交道口的管理水平。本方法适用于不同牵引联锁或闭塞制式的单、双、多线的站内或区间道口。This paper proposes a new method of level crossing protection based on the DX3 level crossing signaling system.The requirement on the level crossing guard to confi rm the completion of level crossing protection and the status of obstruction signals is added to the clearance conditions of train signals.Thus,the clearance conditions of train signals are controlled with the completion status of level crossing protection.When all the conditions are met,the proposed method can ensure traffic safety at the level crossing without delaying the clearance of train signals.Moreover,it greatly reduces traffi c congestion pressure,improves the transport effi ciency of railway trains and road vehicles,and upgrades the management level of railway level crossings.The proposed method is applicable to level crossings in stations and sections of single-track,double-track and multi-track lines with various types of traction interlocking and blocking systems.
