摘要
在对压力脉搏波的分析及中医理论研究基础上,提出了一种多点三维动态压力脉搏波的采集方案,以获得有效的脉象数据用于模拟传统中医诊脉.根据信号功率谱的特点,在数据采集过程中结合了功率谱分析手段动态提取脉象的位置及力度特征,同时通过实验得出脉象变化与压力脉搏波功率谱变化的内在相关性,从而得到一种简单有效的脉象特征分析和提取的实验和研究方法.
Based on an analysis of pulse pressure waves and a study of traditional Chinese medicine theories, a multi-point three-dimensional dynamic pulse pressure wave data collecting method was designed to obtain valid pulse data for simulating traditional pulse diagnosis. Considering the feature of the signal, the method of power spectral density analysis was used during the data collection to extract the position and strength features of the pulse wave on a dynamic mode. At the same time, the pertinence between the changes of pulse image and the power spectral density of pulse waves was found. Thus a kind of simple and efficient experimenting and analyzing method for pulse image feature analysis and extraction is obtained.
