A new method of data preparing and data processing in data mining is given. The decomposition and restructuring algorithm of wavelet packet analysis (WPA) is introduced. The initial data collected by sensor group are denoised and compressed by WPA. The viewpoint about data information identification based on `energy-information' is shown. A new algorithm of data mining using WPA extracting data feature is presented
