State evaluation system, state evaluation device and state evaluation method

摘要

Problem to be solved: to provide a state evaluation system, a state evaluation apparatus and a state evaluation method capable of evaluating the abnormality of industrial equipment with high accuracy.The state evaluation system of the embodiment includes a sensor, a filter, a signal processing unit, and an evaluation unit.The sensor detects an elastic wave generated from the operating industrial equipment.The filter can pass an elastic wave having a frequency characteristic caused by wear occurring in the industrial equipment.The signal processing section extracts a plurality of characteristic quantities using the elastic wave passing through the filter.The evaluation part evaluates the abnormality of the industrial equipment based on the combination of the extracted plurality of characteristic quantities.Diagram
