摘　　要：以不同检测时间的高速铁路接触网动态检测数据为基础,研究拉出值数据的变化特征,通过检测数据对齐和异常值剔除来获得连续的拉出值差值波形,采用基于滑动窗口的拉出值变化识别算法,根据变化窗口中心定位点处的拉出值差值变化情况,准确定位拉出值发生变化的处所。经过线路实测数据的分析验证该方法的有效性。研究结果表明:该方法可以有效识别出拉出值发生异常变化的定位点,提前预警设备恶化趋势。Based on the dynamic detection data of high-speed railway catenary with different detection times,the change characteristics of the stagger data are studied,and the continuous stagger difference waveform is obtained by detecting data alignment and outlier value rejection,and the stagger change recognition algorithm based on sliding window is adopted to accurately locate the place where the stagger changes according to the change of the stagger difference at the central anchor point of the change window.The analysis of line measured data verifies the effectiveness of the proposed method.The results show that this method can effectively identify the anchor point with abnormal change in stagger,and warn the deterioration trend of equipment in advance.
