基于激光扫描的地铁站台门与列车间隙异物检测研究

Study on Foreign Objects Detection in the Gap between Platform Edge Door and Train Based on Laser Scanning

针对地铁站台门与列车之间间隙的安全防护问题,介绍了目前业内广泛采用的激光对射和红外光幕2种自动检测方式,并分析了各自存在的检测问题。提出了基于激光扫描的异物检测方案,包括工作原理、系统设计和安装方式等。该方案具有高可靠性及高安全性、可精确定位障碍物、安装简单且不受限界尺寸影响等特点,实现了对乘客及行车运营(尤其在全自动驾驶模式下)更为可靠的安全防护。

According to the safety protection problem of the gap between platform edge door and train, the two automatic detection methods of laser correlation and infrared light curtain were introduced, which were wide spread adopted in the industry, and the detection problems of each were pointed out. A foreign object detection scheme based on laser scanning was proposed, including working principle, system design and installation method, etc. The solution was characterized by high reliability and high safety, precise positioning of obstacles, simple installation and unlimited by vehicle gauge, etc., and achieved more reliable safety protection for passengers and driving operations, especially in fully automatic driving mode.
