【Abstract】 A method to extract the features of frequency band and qualitative trend in real process measurement signals based on wavelet transform was studied. A new pattern classification algorithm was proposed to induce the relationships of the extracted features and corresponding process conditions. The application results have proved the feasibility and effectiveness of the method.更多还原
