摘　　要：针对短区间列车反向追踪运行的特殊需求,深入研究信号显示关系及其配套点灯电路设计方案。首先,分析车站正线与到发线列车行车组织方式和允许速度的差异性,提出基于实际允许速度设计短区间信号显示关系,取消侧线红灯重复显示,以提升到发线的行车组织效率和车站的通过能力;其次,根据信号“故障-安全”原则及点灯电路技术条件,在兼容现有四显示出站信号机点灯电路的基础上,通过增加灯丝监督继电器,优化反向发车信号显示,以适应短区间反向按四显示追踪运行的需求。经仿真测试和实际应用验证,结果表明该方案能够保障行车安全,提高短区间列车运行效率,为铁路枢纽和繁忙干线短区间特殊信号显示关系优化及点灯电路设计提供参考和借鉴。Aiming at the special demand of train reverse tracking operation in short section,the signal indication relation and design scheme of lighting circuit are deeply studied.Firstly,the differences of train operation organization mode and permissive speed between the main line and the receiving-departure track are analyzed,and a signal indication relation of short section based on the actual permissive speed is designed,and the repeated indication of the red light on the receivingdeparture track is canceled to improve the train operation organization efficiency and the carrying capacity of the station.Secondly,according to the principle of signal fail-safe and the technical conditions of the lighting circuit,the reverse starting signal indication is optimized by adding the filament surveillance relay on the basis of compatibility with the existing four-indication starting signal lighting circuit,so as to meet the needs of reverse four-indication tracking operation in the short section.The simulation test and practical application verify that this scheme can guarantee the running safety and improve the train operation efficiency in short sections.It provides reference for the optimization of special signal indication relation and lighting circuit design in railway hubs and busy trunk lines in short sections.
