城市轨道交通站台门和列车门间隙安全探测系统的设计

Design of Safety Detection System for Gap Between Platform Door and Train Door of Urban Rail Transit

采用基于ToF①的激光探测器(间隙探测系统)可以对站台门与列车门狭缝之间特定平面上的异物进行检测。当列车门与站台门都关闭后,该间隙探测系统能够对列车门与站台门间狭缝平面进行扫描,并检测出狭缝间意外滞留的人员或者物体,并且在狭缝平面上可灵活设置预警区域,对预警区域内是否有物体遮挡进行判别。论文阐述了间隙探测系统的研发背景,并且详细介绍了其系统设计,希望能促进其推广使用,提高地铁运行的效率和安全性。

A laser detector based on ToF①(clearance detection system)can be used to detect foreign bodies on the specific plane between the platform door and the train door slit.When the train door and the platform door are closed,the clearance detection system can scan the slit plane between the train door and the platform door,and detect the people or objects accidentally trapped in the slit plane,and the warning area can be flexibly set on the slit plane to distinguish whether there is object in the warning area.This paper describes the research and development background of the clearance detection system,and introduces its system design in detail,hoping to promote its use and improve the efficiency and safety of subway operation.
