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.

Abnormality determination system and abnormality determination method for processing apparatus

A processing system comprising a loading/unloading section, a processing section and an interface section. The system further comprises a convey mechanism and at least two waiting sections. The convey mechanism can move in either direction between between the loading/unloading section and the interface section, for conveying objects to the processing units included in the processing section and conveying objects in either direction between the loading/unloading section and the interface section. The waiting sections are provided for temporarily holding an object before the convey mechanism conveys an object to the interface section.
