摘要： A computer program causing a computer to execute processing of detecting an abnormality of an industrial machine having a movable part is provided. The computer executes the processing of acquiring physical quantity data on a time-series basis output from a sensor detecting a physical quantity related to a motion of the movable part; converting the physical quantity data on a time-series basis acquired to a time-series data image representing the physical quantity data; inputting the time-series data image converted to a learning model to calculate a feature of the time-series data image, the learning model being trained with a feature of the time-series data image related to the movable part in a normal condition; and determining a presence or an absence of an abnormality of the industrial machine based on the calculated feature.
