<p>PURPOSE:To enable the avoiding of an abnormality diagnosis of a plant by inputting an actual state signal from a man-machine interface element to be compared with a man-machine interface element reference state signal. CONSTITUTION:A man-machine interface element state estimating means 13 inputs a plant state signal (b) from a plant monitoring diagnosis system 19 to estimate a man-machine interface element reference state for each of man- machine interface element reference elements. Then, a comparison/judgment means 15 compares an actual state signal (e) of the man-machine interface element with a reference state signal (d) from the estimating means 13 to judge whether the man-machine interface element is proper or not while the results of the judgment are displayed to an operator with a CRT 16 for display the results of judgment and a warning is sounded. Thus, the presence of abnormality of the man-machine interface element can be judged beforehand.</p> |
