Abstract
In feature value extraction processing step, feature values are extracted from time-series vibroacoustic data in equipment in operation. In machine learning diagnosis step, accumulated are feature values corresponding to normal equipment-operation-state and general measurement data on equipment. Probability distribution model related to correlation between general measurement data and feature values corresponding to normal equipment-operation-state and constructed through machine learning is fed with general-measurement data and feature values extracted in feature value extraction processing step to calculate degree of anomaly based on probability distribution model. In anomalous location estimation step, precalculated damaged-case dataset of degrees of anomaly is compared with actual-measurement dataset of degrees of anomaly calculated from general-measurement data in equipment to obtain degree of similarity for each location in the equipment and output the locations, in order ranked by degrees of similarity for each location in equipment, as locations having high likelihoods of being damaged.
