Abstract:
A tool for monitoring system operation, said tool comprising:a data acquisition unit, said data acquisition unit receiving signals from sensors, said sensors being disposed upon a system being monitored and providing parametric snapshots of system operation; a memory storing a training set, said training set containing a plurality of system vectors, each of said system vectors being representative of an expected operating state of said system being monitored; a processor receiving snapshots from said data acquisition unit and comparing received snapshots with system vectors from said memory, said processor selectively applying a lensing similarity function to said comparison; and an output unit, said processor providing results of said comparison to said output unit, said processor comprising a similarity engine, said similarity engine receiving said snapshots from said acquisition unit and training set vectors from said memory and applying said lensing similarity function to said received vectors to generate a similarity vector, said similarity engine selectively providing said similarity vector to said output device.
