Abstract
A process monitoring system includes: a plurality of field devices configured to measure state quantities in an industrial process implemented in a plant; a trend calculation unit configured to determine the variation trend of the state quantities based on time-sequence data output from each of the plurality of field devices and classify each of the variation trends of the state quantities into one of a pre-established plurality of statuses; a state change judgment unit configured to judge the existence or non-existence of a pre-indicator of a change in the plant state, in accordance with the existence or non-existence of a change in at least one of the statuses classified by the trend calculation unit; and a notification unit configured to notify of judgment results of the state change judgment unit.
