摘要:
城市轨道交通站台门与列车车门间的空隙可能存在着夹人夹物的情况，需要对该间隙空间进行必要的障碍物探测，以实现列车安全发车。应将站台门间隙探测系统的控制逻辑接入城市轨道交通线路的信号系统中。基于站台门间隙探测系统的功能特点，分析了站台门间隙探测系统与信号系统间的控制时序。在此基础上，对站台门间隙探测系统与信号系统之间的接口和控制逻辑进行分析，并重点对控制逻辑中的可选方案进行了技术比对。该探测系统可视为城市轨道交通FAO(全自动运行)线路局部范围的功能补强。
Abstracts:
Since passengers and articles may be caught in the gap between urban rail transit platform door and train door, detecting the obstacles in the clearance space is necessary to ensure the train safe departure, but the control logic of platform door clearance detection system should be connected to the signal system of urban rail transit lines. According to the functional characteristics of platform door clearance detection system, the control sequence between platform door clearance detection and signal system is analyzed. On this basis, the interface and control logic between clearance detection and signal system are studied, and the technical comparison of the optional schemes in control logic is emphasized. This detection system can be regarded as the functional reinforcement for the local scope of urban rail transit FAO (fully automatic operation) line.
