METHOD OF DIAGNOSING OF PREEFECTIVE STATE OF TECHNICAL OBJECT Russian patent published in 2009 - IPC G05B23/02 

FIELD: physics, computer facilities.

SUBSTANCE: method of diagnosing of the predefective state of technical object concerns technical cybernetics and can be used in systems of diagnosing of a state of the difficult technical objects. At the given way the separate parametres are allocated, which are signs of its technical state, signals for all signs of states of the chosen group of classes are measured, the class in the chosen group of classes of a state is spotted with the peak medial value of the empirical correlation relation which is an actual class of a state. Time of functioning of diagnosed technical object is measured and the signal corresponding to in addition analised priority sign, characterising a state of the allocated plurality of builders of the diagnosed technical object which unworkable functioning can lead to catastrophic consequences is nonsinglely periodically measured. In case of revealing of several classes of states with identical (close) peak medial values of the empirical correlation relation, for each of these classes of states the relation is calculated between quantities of an intergroup variance and the grand average, the calculated relations are compared and by results of comparison the solution on a select of an actual class of a state for which the peak quantity of the calculated relation is made.

EFFECT: increase of reliability of diagnosing of a state of difficult technical objects before failure.
