基于多传感融合的地铁站台门与列车门间隙防夹探测系统研究

地铁站台门与列车门之间的间隙探测,是地铁交通行业的疑难问题。目前国内地铁主要采用激光对射、红外对射和车尾设置瞭望灯带的探测方案,但这些方案存在误报率高、定位精度低以及探测盲区等问题,从而降低地铁运行效率,且存在一定的安全隐患。针对目前间隙探测技术的局限性,以及未来全自动运行线路更高的安全需求,文章提出一种基于多传感融合的地铁站台门与列车门间隙防夹探测系统的方案。该方案可克服传统方案的局限性,实现障碍物的可靠、精准、智能识别,继而提高未来全自动运行线路的运营效率以及安全性。

On anti-pinch detection system of metro platform door and train door gap based on multi sensor fusion

Gap detection between platform door and train door is a challenge in metro transportation industry.At present,the metro in China mainly uses the laser beam detection,infrared beam and lookout light band EOT,but these schemes have the problems of high false alarm rate,low positioning accuracy and detection blind area,deteriorating the metro operation efficiency,and there are some safety risks.In view of the constraints of traditional gap detection technology and the higher safety requirements of future fully automated operation lines,this paper proposes a scheme of metro platform door and train door gap anti-pinch detection system based on multisensor fusion.This scheme overcomes the constraints of the traditional schemes,realizes reliable,accurate and intelligent identification of obstacles,and improves the operation effi ciency and safety of fully automated operation lines in the future.
