信号与间隙探测接口方案设计分析

摘要：随着全自动运行项目的日益增多，间隙探测作为防护乘客安全的第二道隐形门，其安全作用越来重要。为避免间隙探测系统在启动和停止状态转换时影响列车进出站效率和产生安全隐患，研究分析了一种“信号—间隙探测”接口方案。该方案定义了接口内容、正常和故障场景，并针对安全风险提出了改进措施。

Abstract： With the increasing number of Fully Automatic Operation （FAO） projects， Gap Detection System （GDS）， as the second invisible door for protecting passenger safety， has become increasingly important in terms of safety. To prevent the gap detection system from affecting the efficiency of train entry and exit and causing safety hazards during the transition between start and stop states， a “signal-gap detection” interface scheme is studied and analyzed. This scheme defines the interface content， normal and fault scenarios， and proposes improvement measures for safety risks.
