Item Intelligent sensor based on acoustic emission analysis applied to gear fault diagnosis(IEEE Computer Society, 2013) Zurita, Daniel; Delgado, Miguel; Ortega, Juan Antonio; Romeral, Luis; FACTORYThe development of intelligent and autonomous monitoring systems applied to rotating machinery, represents the evolution towards the automatic industrial plants supervision. In this regard, an acoustic emission based intelligent sensor is presented in this work. The proposed sensor records regularly the acoustic emission signal generated by gearboxes. A time domain statistical analysis is applied in order to characterize the acquired data. Afterwards, a neural network based algorithm is applied to detect gear fault patterns. Finally, the diagnosis result is sent through a wireless transceiver to the central control unit. Moreover, in order to reach a real autonomous operation, the sensor power is approached by different energy harvesting solutions.
