城市轨道安全门智能门机控制系统研究

Intelligent Control System of platform screen door for Urban Transit

本文针对现有城市轨道安全门控制系统存在安全门夹人或挤人的问题,提出了基于图像特征匹配城市轨道安全门智能控制系统和方法。智能控制系统采用图像特征提取和匹配的方法,不仅能有效地减少图像目标识别运算时间,而且能实时判断列车车门和站台安全门之间是否存在异物,以及列车进出站的状态,做出智能化的判断和决策,从而能有效的保障列车安全节能运行及乘客的安全,以及安全门系统安全性、可靠性和可用性。

The existing Intelligent Control System of platform screen door was with the problems of clip or squeeze.The methods of image feature extraction and matching were put forward for solving the problems.The methods could not only effectively reduce operating time of the image target recognition,but also could realtime judge whether there was foreign body between exit train doors and platform,as well as the state of train in or train out of the station,let the train make intelligent judgment and decision,effectively ensure the safety of train running and the safety of the passengers,as well as the security,reliability and availability of the existing system.
