地铁站台屏蔽门系统隐患分析及改进研究

Analysis and Improvement of the Hidden Dangers of Platform Screen Door

城市轨道交通车站站台屏蔽门系统是保障乘客安全和地铁系统正常运行的一个重要安全装置。因地铁列车门与站台屏蔽门、列车与站台之间存在一定间隙,时有乘客被夹和踏空等安全事故出现。针对存在的隐患,提出了解决办法:在站台屏蔽门和列车门之间加装激光传感器阵列和自动伸缩踏板。该解决方案对于现有系统的改造较为简单。在实验室做出了模拟样机,经试验证明对站台屏蔽门的安全事故有很好的防范作用。

In rail transit the platform screen door （PSD） is an important device to protect the safety of passengers and the subway system, but there is a gap between the subway train doors and the platform screen doors,also between the train and the platform, incidents often occur when passen- gers get on/off the train. Aiming at these hidden dangers, a solution scheme is proposed in the paper, that is to install laser sensor arrays and automated retractable pedals be- tween the PSD and the train door, this scheme is easy to improve the existing PSD system. A prototype in the laboratory has been made and the experiment has verified that the scheme is of good preventive effect.
