METHOD FOR DETECTING POSITION OF TUBE SUPPORT SIGNALS IN EDDY CURRENTS RAW DATA AND METHOD FOR DETECTING POSITION OF DETECT IN EDDY CURRENT TESTING

摘要

A method for locating a signal corresponding to a structure in eddy current source data, the method comprising: reading eddy current source data in an eddy current data group; normalizing voltage and phase of eddy current source data; Extracting and patterning a signal corresponding to the structure from the eddy current source data to obtain a structure pattern signal, and determining a position of the signal corresponding to the structure in the eddy current source data based on the structure pattern signal. do.The present invention also provides a method of locating defective portions derived from an eddy current test, comprising: reading eddy current source data in an eddy current data group; normalizing voltage and phase of eddy current source data; Extracting and patterning a signal corresponding to the structure from the eddy current source data to obtain a structure pattern signal, determining the position of the signal corresponding to the structure in the eddy current source data based on the structure pattern signal, Extracting an eddy current signal corresponding to the defect from the eddy current source data in the phase, determining the position of the eddy current signal corresponding to the defect based on the position of the signal corresponding to the detected structure, Determining the position of the defective part based on the position of the defective part .
