Risk Space Analysis and Technical Requirements for Foreign Object Detection System

为了规范地铁风险空间异物检测系统的设计与安装,切合未来地铁无人驾驶的需求,首先分析地铁站台屏蔽门与列车门之间风险空间的风险特性与异物事件的发生原因,对比现有防夹装置和风险空间异物检测技术的优缺点,然后根据异物事件的异物体积、风险性与危害程度进行风险等级划分,并对现有异物检测系统进行检测水平评估,最后总结未来地铁无人驾驶环境下的异物检测系统必须达到理想化人工瞭望灯带技术及其以上的检测水平,本研究为未来地铁无人驾驶技术和异物检测技术的发展与应用提供参考。

In order to standardize the design and installation of the subway risk space foreign object detection system and meet the needs of future subway unmanned driving, the risk characteristics of the risk space and the cause of the foreign objects between the subway screen doors and the train doors are analyzed, and the advantages and disadvantages of the existing anti-trap device and foreign object detection system are compared. Then, according to the volume of foreign objects, and risk and damage degree of the foreign object incident, the risk rate of the risk space incident is determined, and the detection level of foreign object detection system is evaluated. Finally, it is concluded that, in future subway unmanned driving environment, the risk space foreign object detection system must reach the detection level above that of the manual detection under ideal conditions. This study provides some reference for the development and application of future subway unmanned driving and foreign object detection.
