FEATURE EXTRACTING DEVICE FOR PLANT OPERATION DATA

摘要

PROBLEM TO BE SOLVED: To provide a process operation data sorting device with which the feature of input case can be properly extracted even when the time base of an input case is not coincident with the time base of a comparative case. ;SOLUTION: A feature extracting means 3 selects a standard case corresponding to an input case, extracts the feature of the input case based on the difference of a selected standard case and input case, and outputs an output case for which the extracted feature is added to the input case. An extracted result confirming means 4 displays the output case on a screen for confirming the extracted feature. A time point defining means 5 defines the desired time point to be made coincident between the time bases of the standard case and the input case. A time base transforming means 6 compares the time bases of the standard case and the input case while referring to the defined time point and when these time bases are not coincident, the time base of the input case is changed and made correspondent to the time base of the standard case.;COPYRIGHT: (C)1998,JPO
