Fault detection system and associated method

摘要

A method 300 implemented using a controller based device 190 includes receiving 302 a measured electrical signal from an electrical device 150 of an electromechanical device 110 and receiving a measured vibration signal from a mechanical device 140 of the electromechanical device 110, coupled to the electrical device 150. The method 300 further includes determining 306 a first signal signature based on the measured electrical signal and determining 308 a second signal signature based on the measured vibration signal. The method 300 also includes determining 312 a diagnostic parameter based on the first signal signature and the second signal signature and determining 318 a fault in the mechanical device 140 based on the diagnostic parameter.
