新型地铁站台门与车门之间顶置式防夹人自动探测系统的设计

针对地铁车站站台门与车门之间空隙存在夹人夹物的安全问题,介绍了目前应用较广泛的只适合于直线站台的通过司机瞭望检测方式的瞭望灯带,以及受限界尺寸影响的激光对射探测方式存在检测盲区的问题。提出了基于机器视觉的顶置式防夹人夹物的自动探测设计方案。该方案的安装不受限界尺寸影响,探测范围广,盲区小,实现了对乘客及行车运营更为可靠的安全防护。

Design of Top Mounted Anti-pinch Automatic Detection System between Platform Screen Door and Train Door

To avoid clamping problems caused by the gap between subway platform door and train door,the widely used outlook light band is introduced,which is only suitable for the linear platform and driver's outlook detection,because of the blind area in laser detection affected by the limited size.So,the design of the top mounted foreign body detection based on machine vision is put forward,which has a wide detection range,smaller blind area and could not be affected by the limit of installation,the safety of passengers and more reliable protection for the vehicle operation are achieved.
