ACOUSTIC EMISSION-BASED DEFECT SIGNAL DETECTION DEVICE AND METHOD

摘要

A method for evaluating the degree of abnormality in facility data according to an embodiment of the present invention includes: a step for generating boundary data, which is distinguishable from normal data, through a boundary data generation algorithm; a step for generating an evaluation model which learns the boundary data and evaluates the degree of deviation from the normal data; a step for generating a two-dimensional map for visualizing the degree of evaluation of the evaluation model; a step for generating a two-dimensional evaluation map by evaluating, for each position, the data mapped onto the two-dimensional map; and a step for determining a two-dimensional map position for an input signal, and evaluating the degree of abnormality of the input signal.
