| Abstract: | This paper presented a new prognostic method for surface scrape of wheel with combination of rough set and wavelet analysis. On the basis of analyzing the hazards of surface scrape and characteristics of multi-sensor data fusion,rough set theory and wavelet analysis were introduced into multi-sensor data fusion. This paper firstly studied the techniques of feature extraction by wavelet analysis and the reduction arithmetic of rough set theory.Secondly a data fusion method based on rough set theory with feature extraction of wavelet was designed. According to the method, wavelet extracts multi-characteristics from multi-sensor signals, and rough set selects characteristics and forms a set of rules which can accomplish the prognosis for surface scrape of the wheel. |
