<p>PURPOSE:To provide the monitor screen on which a plant state showing abnormality or an abnormality sign and the direction of a change are grasped on a plant system map without increasing the amount of data. CONSTITUTION:An analytic process part 14 which simulates the plant on the basis of time-series plant data inputted periodically at respective monitor points finds time-seires predicted plant data at the respective monitor points, and a symbolizing process part 15 retrieves patterns similar to the variation trend of the time-series predicted plant data in a symbolization dictionary file and converts the time-series predicted plant data into symbolization data on the names set in, the patterns, e.g. 'sudden fall and sudden rise'. A map symbol converting process part 16 change the symbolization data of the respective monitor points into map symbols with corresponding attribute information by referring to the attribute information for drawing the map symbols of the places of the respective monitor points and a symbolization data conversion table 37. A monitor screen display process part 17 displays the monitor screen of the plant system map consisting of map symbol on which plant states are reflected.</p> |
