Abstract: The characteristics of the train doors and their emergency devices are analyzed in the scenario where a passenger triggers an emergency handle of an FAO train. The “maintain doors closed” signal, as the final authorization of opening train doors, is added in the onboard ATC and vehicle interface. The “maintain doors closed” signal can play a protective role when an emergency handle is triggered, as demonstrated by the research on the sequences of signals or information between onboard ATC and the vehicle in various scenarios.

Key words: maintain doors closed, emergency handle, train doors, fully automatic operation

摘要： 针对乘客触发全自动驾驶列车车门紧急手柄的情况，分析车门及其紧急装置的特性，在车载ATC和车辆接口中增加保持门关闭信号作为车门打开的最终授权，通过研究各种场景下车载ATC和车辆之间信号或信息的时序，保持门关闭信号可以对触发车门紧急手柄的情况起到防护作用。
