【摘要】 基于小波变换的时频域局部化特性及人工神经网络的非线性映射特性，将小波变换和人工种经网络的优点结合起来，用加权法实现信息的初级融合，用小波变换实现特征提取，再用人工种经网络实现信息的二级融合；介绍网络的构造方法和信息处理的步骤。更多还原

【Abstract】 According to the time-frequencylocalization characteristics of the wavelet trans-form (WT) and the nonlinear mapping of theneural network, this paper presents the neuralnetwork data fusion fault diagnosis methodbased on wavelet transform. The network con-struction and the signal processing steps are in-troduced in details. It proves the method efficientin fault diagnosis, which is expected to have awide application.更多还原
