间接接触网自动检测方法的研究

Study on Indirect Methods for Automatic Detection of Overhead Contact Line

提出了一种通过对受电弓状态的检测,间接判断接触网是否有故障可能的方法。利用图像处理技术,采用霍夫变换分析采集受电弓图像的倾斜角度。建立受电弓形状模板,提出受电弓重合面积比这一参数,利用模板匹配法分析受电弓形变情况。实验证明,该方法可以有效判断受电弓的倾斜和变形情况,从而实现接触网故障报警。

This paper presented an indirect contact line detection method, which detected the contact line condition by analyzing the pantograph parameters. The angle of pantograph inclination was calculated based on Hough transform. Pantograph shape model was established. The overlap area of pantograph image and the model was calculated to estimate the pantograph shape condition based on template matching. Test proved that the proposed method can estimate condition of the pantograph effectively, which can achieve the contact line damage alert.
