MONITORING SYSTEM AND METHOD

Abstract: a monitoring system includes a vibrating module, an acoustic emission sensor and a processing device. the vibrating module is configured to vibrate a target object. the acoustic emission sensor is configured to sense an acoustic emission signal with liquid generated by a deformation of the target object. the processing device is connected to the vibrating module and the acoustic emission sensor, and is configured to receive the acoustic emission signal and perform: dividing the acoustic emission signal into signal segments having a same time length, performing a time-frequency transformation on the signal segments to generate power spectrums, performing an average calculation on the power spectrums to generate a power spectral density, and adjusting or maintaining an operation parameter of the vibrating module according to a comparison result between a default difference value and a difference value between a maximum value of the power spectral density and a set value.
