The invention discloses an overhead line system comprehensive diagnosis method based on multi-source detection parameters. The method comprises the following steps: S1, automatically aligning detection data; s2, performing standard state generation on the automatically aligned detection data; and S3, carrying out potential defect analysis, including time domain analysis and frequency domain analysis, on the detection data in the standard state to obtain potential defects of the overhead line system. The invention relates to an overhead line system comprehensive diagnosis method based on multi-source detection parameters. The overhead line system comprehensive diagnosis method mainly utilizes multi-dimensional detection data for multiple times to carry out comprehensive diagnosis evaluation on an overhead line system. The multi-dimensional detection data includes but is not limited to a pull-out value, conductive height, pantograph-catenary contact force and a hard point.
Description
technical field [0001] The invention relates to the field of catenary detection, in particular to a catenary comprehensive diagnosis method based on multi-source detection parameters. Background technique [0002] With the rapid development of urban rail transit, the catenary detection system has become more accurate and comprehensive, and can comprehensively monitor the status of the catenary from multiple aspects. At present, the use of detection data is mainly limited to the judgment of whether it exceeds the limit, and the threshold setting of the limit is generally large, and the data that does not exceed the limit is rarely concerned. Existing methods for the use of detection data are: 1. Use fault tree analysis, event number analysis, and reliability theory to establish the reliability model of the entire catenary system; 2. Based on the Hilbert-Huang transform, the catenary system Analyze the detection data to evaluate the entire operating state of the catenary; 3. ...
