基于分形几何的信号特征提取技术及其应用研究

摘要

针对分形客观展现事物原貌的特点，从工程应用的角度分别对信号的分形性验证、有效分析区间的确定、分形性描述和刻画、设备状态的趋势分析等方面作了探讨，形成了基于分形几何的信号特征提取技术，并描绘出基于分形几何的设备故障诊断模式.%According to the specialty fractal，an integrated and usefulcharacteristics extraction model for signals is presented. It includes validating the fractal nature, determining the efficient analysis region，describing the fractal nature and analyzing the equipment′s state tendency.
