全自动运行系统已经成为城市轨道交通的主流发展方向，但出于安全和应急响应及时性等因素考虑，目前我国全自动运行线路仍以人员值守方式运营，未能充分发挥“全自动”优势。为了解决运营单位的后顾之忧，提升设备故障应急处置效率，本文在广泛调研多个城市全自动运行线路应急预案的基础上，提出以行车关键设备为核心的FAO线路设备相关应急预案框架。面向现行预案的完备性不足、流程不明确的问题，提出融合失效模式分析和熵权法的故障处置应急预案设计方法。考虑故障影响的严酷度、发生概率、影响范围、隔离处置难度、运营恢复难度五方面因素，结合系统设计信息和运营日志数据客观计算故障综合影响指标，并以此为依据确定故障处置策略，进而设计应急预案。最后，以计轴设备为案例，借助某线路85个月故障日志数据，完成设备故障模式分级并针对性设计应急预案。结果表明，故障处置预案的完备性和可操作性得到有效改善。

The fully automatic operation (FAO) system has become the mainstream of urban rail transit in China. Considering factors such as safety and timeliness of emergency response, at present, FAO lines in China still operate in a staffed manner, failing to give full play to the "fully automatic" advantage. To address the concerns of operation units and improve the efficiency of emergency response for equipment failures, this paper proposes an emergency plan framework related to FAO line directed by key equipment based on extensive survey on the current emergency plans of fully automatic operation lines in multiple cities. Aiming at the problems of insufficient completeness and poor operability of current emergency plans, a design method of emergency plans for fault handling that integrates failure mode analysis and entropy weight method is proposed. Considering five factors such as the severity, occurrence probability, scope of influence, difficulty of isolation, and difficulty of operation restoration, objectively calculate the comprehensive fault impact index, combined with system design information and operation log data. Based on this impact index, operators can determine the fault handling strategy and design the emergency plans. Finally, taking the axle counter equipment as an example, the equipment fault mode is classified and an emergency plan is designed targeted with 85 months of fault log data of a certain line. The results show that the completeness and operability of the failure handling emergency plan have been effectively improved.
