ABSTRACT:
A signal classifier system is disclosed that includes an on-line apparatus for monitoring various electrical signal inputs derived from vibration signals without data interruption, and providing an output from each of several levels of classifications. Classification is by a three-level classification algorithm. A first level of classification provides for the independent processing without structural or operational information of each signal input. The output of the first level is stored according to a strain gauge in a spatial file. The second level of classification provides a combination of the output of the spatial file with structural information (such as compressor structural information) and on-line operational information to provide an output indicative of event probabilities which are stored. Finally, in a third level of classification, there is a temporal combination of event probabilities and on-line operational information, off-line a priori information and data from sensors to produce an output indicative of running probabilities for a particular phenomena. The final output will provide a prediction, for example, of a source of vibration and other aeromechanical phenomena during operation of turbomachinery, such as a gas turbine engine.
