轨道交通站台门与列车间隙障碍物探测方法

Detection method for the barrier between the platform and the train of the rail transit station

轨道交通已作为城市公共交通系统中的一个重要组成部分,站台门与列车间隙障碍物探测则对安全运营起到非常重要的作用。本文将对站台门与列车门间隙障碍物探测的物理方法、光电技术、图像处理技术三种方法分别进行论述,前两种方法已广泛运用在目前站台门系统上,图像处理技术也已在国内部分地铁站台上进行试用,随着地铁安全运营要求的不断提高,图像处理技术将逐步应用在站台门系统上。

As the city rail transit has been an important component part of the public transport system,platform screen door and train clearance obstacle detection for safe operations play a very important role.In this article,the physical method,photoelectric technology and image processing technology of detecting obstacles between platform and train are discussed respectively.The first two methods have been widely used in the current platform screen door system,and image processing technology has been tried on some domestic railway platforms.With the continuous improvement of the requirements for safe operation of metro,image processing technology will be gradually applied on the platform screen door system.
