<p>PURPOSE:To understand the inference process well by selecting information of an explanatory diagram of the inference process in correspondence to an inference point designated by an operator, and displaying the information at a display device in accordance with information of a color change/text information table. CONSTITUTION:The presence or absence of abnormality in a process value of a plant 4 is detected by an abnormality detecting means 12 through an input processing means 11, and the generation of an abnormality is informed to an inference executing means 14. The content of the abnormality is detected and the reason for the abnormality are inferred with use of a knowledge base 13 in the means 14. The inferred result and guidance information for the reason of the abnormality are sent to a display device 2 by a guidance/result information means 15. Then, a color change/text interface means 16 detects whether to display the color change or the text in accordance with the inferred result of the means 14, and a required parameter is preserved in a color change/text information table 17. An explanatory diagram selecting means 20 displays the explanatory diagram of the inference process at the device 2 via a display means 21 by a selecting signal from an input device 3.</p> |
