Abnormality diagnostic device, abnormality diagnosis method and abnormality diagnosis program

摘要

Problem: the abnormality of the self circulating type driving apparatus is diagnosed more reliably than in the prior art.First vibration characteristic data detected in the normal state of the self circulating type driving deviceAnd a data acquisition section 131 for acquiring the second vibration characteristic data detected at the time of diagnosis, andEach of the first vibration characteristic data and the second vibration characteristic data is processed by a statistical information filter.For each of the first vibration characteristic data and the second vibration characteristic data after the treatment, respectivelyA parameter calculating section 132 for calculating characteristic parameters including at least two characteristic parameters andPrincipal component analysis section 134 extracts two main components by normalized feature parameter for normalized feature parametersBased on the Euclidean distance between the first and second points corresponding to the two main components extracted from the characteristic parameters associated with each of the first vibrational characteristic data and the second vibration characteristic dataAbnormality diagnosis unit 135 to diagnose abnormality.Diagram
