发明名称 ABNORMALITY DETERMINATION SYSTEM AND ABNORMALITY DETERMINATION METHOD FOR PROCESSING APPARATUS
摘要 An abnormality determination system for a processing apparatus includes: a data acquiring section that acquires time-series data changing with time from a signal outputted by a sensor installed in a processing apparatus for processing a processing object; a data selecting section that selects only model data, which is useful time-series data, from the time-series data acquired by the data acquiring section; a threshold value setting section configured to calculate variable threshold value data changing with time from the model data selected by the data selecting section; and a determining section configured to determine an occurrence of an abnormality by comparing time-series data to be monitored, acquired by the data acquiring section, with the variable threshold value data. The selection of model data is performed based on an evaluation performed by an inspection device which is configured to evaluate a processing result of the processing object performed by the processing apparatus.
