基于卡尔曼滤波的蒙医脉象采集分析系统

Mongolian Medicine Pulse Acquisition and Analysis System Based on Kalman Filter

针对蒙医诊断学现代化的要求,设计了蒙医脉象采集分析系统.该系统可以对病人的脉象进行采集,并根据蒙医文献资料中总结的寒热十二种脉象进行疾病分类.根据脉诊过程中的指压取脉过程,设计传感器自动加压装置.采集信号过程中,存在杂波和信号干扰.设计了卡尔曼滤波器,对采集的脉搏信号进行优化.脉象信息采集实验表明,卡尔曼滤波器可以有效地提取脉象特征信号,对后续的脉象频率、幅度、变化等一系列数字化信息的获取有重要意义.

For the requirements of modernization of Mongolian medicine diagnostics,a Mongolian medicine pulse acquisition and analysis system is designed.The system can collect patient's pulse,and classify the diseases according to the twelve kinds of chills and fever pulse signal summarized in Mongolian literature.According to the pulse extraction by finger pressure in pulse diagnosis,the automatic pressure device of the sensor is designed.In the process of signal acquisition,there are problems of clutter and signal interference.Kalman filter is designed to optimize the collected pulse signal.Pulse information acquisition experiments show that the Kalman filter can effectively extract the characteristic pulse signal,which is of great significance to acquire a series of subsequent digital information such as pulse frequency,amplitude and change.
