<p>PURPOSE:To shorten a time required to recognize an abnormal state by an operator by displaying the abnormal part and the abnormal level of a plant on a CRT display device in a chart. CONSTITUTION:An abnormal data detecting means 3 finds the abnormal part and the level of the abnormal state in an object to be monitored, and generates display data on the CRT display device 7 based on the abnormal part and the level of the abnormal state of the object to be monitored by a data generating means 4 for display. Also, the display format on the CRT display device 7 of a plant state is expressed in a crisscross matrix table by arranging the objects A0, A1, A2...Am horizontally and arranging monitoring items B0, B1, B2...Bl in sequence of alarm importance vertically. Also, as for display in the matrix in an individual group, levels by stages from the abnormal state (quality and quantity) of the monitoring item to a normal state are provided, and color switching and display in bar chart corresponding to the level is performed. In such a way, the operator can recognize the level of the abnormal state rapidly.</p> |
