Patent ID: 8688246

Claim:
An operation monitoring system for a processing apparatus, the processing apparatus comprising: moveable parts disposed to form a predetermined processing environment within a processing chamber in which a predetermined processing is performed on an object to be processed; and a control means for controlling the operation of each of the moveable parts, the operation monitoring system having a vibration detection means for detecting waveforms of vibrations to be generated accompanied by the operation of the moveable parts, wherein, when control by the control means is performed to operate any one of the moveable parts, there are obtained: event data corresponding to the control; and waveforms of vibrations of all the moveable parts that are detected by the vibration detection means and that are moving simultaneously, and only when any one of the movable parts corresponding to the event data is operated, the change in the waveform is monitored and, if the waveform has changed beyond a predetermined range, the processing apparatus is judged to be abnormal.
