Abnormality detection program, abnormality detection device, and abnormality detection method

Abstract

A non-transitory computer-readable recording medium having stored therein an abnormality detection program for causing a computer to execute a process, the process includes referring to a storage that stores a plurality of determination criteria for each of processes based on a rotation frequency of the rotating part and harmonic frequencies of the rotation frequency in each of a plurality of processes, the rotation frequency and the harmonic frequencies of the rotation frequency being specified from a frequency spectrum of vibration data obtained by measuring, by a sensor, vibration of a monitoring target device that executes the plurality of processes in a predetermined order by using a rotating part that rotates, and detecting occurrence of an abnormality of the monitoring target device from the vibration data measured by the sensor based on the predetermined order and the plurality of determination criteria for each of the processes.
