PLANT DATA ESTIMATION SYSTEM AND METHOD, CONDENSER VACUUM MONITORING METHOD, DATA MINING METHOD, AND PROGRAM |
摘要 |
<p><P>PROBLEM TO BE SOLVED: To efficiently extract and process data correlated with plant data that is a monitoring target to find out a sign of minute abnormality hiding in a normal range, particularly when a plurality of operation modes is provided for a plant. <P>SOLUTION: A plant data estimation system has: a data registration means 22 storing the data on a plant; a multimode determination means 70 determining whether or not a plurality of operation modes of the plant is present on the basis of the data; an evaluation standard configuration means 23 temporarily calculating a correlation approximate expression with the other data item in each a monitoring target data item, eliminating defective data on the basis of deviation between a value by the correlation approximate expression and actual data, and conclusively calculating at least the correlation approximate expression and an evaluation standard including a standard deviation, by use of the data after the elimination; a data evaluation means 24 evaluating the data on the plant by use of the evaluation standard actually calculated by the evaluation standard configuration means 23; and a state display means 26 displaying an evaluation result by the data evaluation means. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
