Method of pantograph slide wear detection of urban rail trains based on laser displacement sensor

针对城市轨道交通(简称:城轨)列车受电弓滑板磨耗检测精度较低的问题,提出了一种基于激光位移传感器的城轨列车受电弓滑板磨耗检测方法。设计了受电弓滑板磨耗检测装置。采用该检测装置,通过数据筛选、数据融合和倾斜校正,获取受电弓滑板的实际轮廓线;将受电弓滑板的实际轮廓线与标准轮廓线进行曲线配准,获得受电弓滑板的磨耗曲线,实现受电弓滑板磨耗状态检测。在实验室搭建受电弓滑板磨耗检测装置进行实验,实验结果表明,与传统的检测方法相比,该检测方法具有较好的检测精度,符合城轨列车受电弓滑板磨耗测检测的实际要求。

Aiming at the low detection accuracy of pantograph slider wear for urban rail trains,this paper proposed a method of pantograph slider wear detection of urban rail trains based on the laser displacement sensor.The paper designed a wear detection device for the pantograph slider.By using this detection device,the paper obtained the actual wear contour of the pantograph slider by data filtering,data fusion and slider correction,matched the actual contour line with the standard contour line of the pantograph slider to obtain the wear curve of the pantograph slider plate,and achieved the detection of the wear status of the pantograph slider.By establishing a wear detection device for the pantograph slider in the laboratory for experiments,the experimental results show that the proposed method has good detection accuracy of pantograph slider wear compared with the traditional detection methods,and can meet the practical requirements for urban rail trains.
