Abstract
The invention discloses a real-time detection system for detecting the real-time machining by a rotating machine or rotating quality thereof. The real-time detection system comprises a signal capture module, a preprocessor, a processor and a comparison module. The signal capture module is used to capture a time-sequence signal of the rotating machine. The preprocessor is coupled to the signal capture module for receiving the time-sequence signal and generating a stationary time-sequence signal. The processor is coupled to the preprocessor for receiving the stationary time-sequence signal and calculating a plurality of entropies of the stationary time-sequence signal. The comparison module with an entropy table or a feature judgment mechanism of the entropy variation is coupled to the processor for receiving the plurality of entropy and comparing the plurality of entropy according to the entropy table or the feature judgment of the entropy variation and generating a quality signal.
