Research on Stuck Recognition of Catenary Compensation Device Based on Data Characteristics
To find anomalies of mid-point anchors and catenary compensation devices,the research paper summarizes data characteristics and proposes the corresponding algorithm according to the waveform data collected by high-speed railway pantograph and catenary comprehensive detection device(1C).Select pantograph-catenary contact force and height of contact line as two characteristic variables for judging such defects.After data pre-processing,calculate the standard deviation of pantograph-catenary contact force within a span.The upper boundary line is formed by moving sliding window of height of contact line and using corresponding rules.Combined with characteristics of the waveform data,determine the threshold value and make logical judgments to obtain the abnormal location kilometer mark.Through the calculation and analysis of typical lines,the results show that the method can identify the defects,which can provide data support for finding such defects quickly and related analysis.
