Production equipment monitoring equipment, production equipment monitoring method and production equipment monitoring program

摘要

In order to accurately determine the abnormality degree of the production equipment based on the log data, the learning unit (44) determines the text feature amount (for example, the text feature amount obtained from the number of texts included in the plurality of log data obtained in the predetermined process of the production equipment). , The first principal component and the second principal component) and the production history information of the production facility, and learns a classification rule for classifying normality/abnormality of the production facility from the text feature quantity, and the extraction unit (46) The text feature amount of the log data of the monitoring target obtained in the predetermined process of the production facility is extracted, and the determination unit (48) determines the log data of the monitoring target based on the extracted text feature amount and the classification rule. The normality/abnormality of the production equipment when it is obtained is determined.
