Abnormal symptom diagnostic apparatus and abnormal symptom diagnostic methods

摘要

The present invention I provide an abnormal symptom diagnostic equipment such as for diagnosing the presence or absence of abnormal sign of mechanical equipment with a high degree of accuracy. A abnormal sign diagnosing apparatus divides the time the series data acquisition unit, a plurality of time periods the operation schedule of the machinery to obtain the time-series data including the detected value of a plurality of sensors installed on the machine equipment , the clustering means 161 for performing clustering in each time zone, the diagnostic means 162 for diagnosing the presence or absence of abnormality sign of mechanical equipment using the clusters generated or updated by the clustering means 161 includes a clustering section 161, It was added using a normal time series data acquired in the past for each time zone and a cluster generating unit 1611d for generating the cluster, time-series data that is diagnosed as no abnormality prediction by the diagnostic means 162 in the cluster member It has, and the cluster update section 1612d to be updated. .BACKGROUND
