摘要
提出一种基于车载激光测距仪的铁路障碍物检测方案,该方案通过在列车头部安装激光发射及接收装置对列车前方障碍物进行检测。检测系统实时发射激光光束,当列车前方存在障碍物时激光发生反射,返回激光被接收装置接收,再通过测量激光的飞行时间推算出目标距离。该方案不仅能够发现线路障碍物,还能获取障碍物与列车之间的距离信息及移动障碍物的速度信息,为车载安全计算机生成列车自动防护曲线提供数据支持。
A detection scheme is put forward based on on-board laser rangefinder in this paper. Laser emitting and receiving devices are installed on the train head. A laser beam is emitted forward in real time and it will reflect if there are obstacles on the rail. Then the receiving device take over the return signal and the object distance is achieved through mearing the laser flight time. Apart from obstacle detection, the range and velocity information will be obtained through this scheme as well. It can provide data support to the on-board computer for generating distance-to-go profile.
