Recognition Method for Stagger Change of Overhead Contact Line Based on Data Characteristics
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.
