Construction method of power transmission fitting dynamic matrix defect focusing algorithm

Abstract

The invention discloses a construction method of a power transmission fitting dynamic matrix defect focusing algorithm. The construction method comprises the following steps: performing full-matrix capture through a phased array probe, acquiring FMC data, dividing a detection area into a plurality of pixel points, and setting a focusing point; carrying out delay correction on the signal based on propagation time calculation, and carrying out dynamic weight distribution and focusing superposition on the signal after delay correction based on signal quality to generate a signal intensity matrix; and carrying out multi-frequency signal fusion and multi-mode signal conjoint analysis on the superposed signal matrix, generating a three-dimensional imaging graph based on the optimized signal, and carrying out defect feature extraction and classification labeling by using a deep learning model. According to the invention, the power transmission fitting defect detection efficiency and precision are significantly improved, and powerful technical support is provided for safe operation of a power transmission line.
