摘要
在城市轨道交通网络化进程加速与城际铁路深度融合的背景下,高密度、大客流的轨道交通运营体系已趋于成熟。然而,既有信号系统在极端工况下面临着显著挑战,包括单一列车晚点易引发连锁延误,且故障处置机制响应滞后,导致高峰期客流拥堵加剧。针对上述瓶颈,文中提出了列车降级场景下的3种信号技术方案,基于系统架构、控制逻辑与设备冗余设计的技术原理,对比分析了其安全性、可靠性、经济性等特征。
Against the backdrop of the accelerated process of urban rail transit networking and the deep integration of intercity railways,the high-density and high passenger flow rail transit operation system has become mature.However,existing signal systems face significant challenges under extreme operating conditions,including the risk of chain delays caused by single train delays,and delayed response of fault handling mechanisms,leading to increased passenger congestion during peak hours.In response to the above bottlenecks,this paper proposes three signal technology solutions for train degradation scenarios,based on the technical principles of system architecture,control logic,and equipment redundancy design,and compares and analyzes their safety,reliability,economy,and other characteristics.
