经络电信号的测量与分析

Detection and analysis system for meridian signal

本文给出了一种经络穴位信号的采集与处理系统的设计。该系统以AD620、OP07等器件做为放大电路核心元件,针对经络穴位信号的特点,对由电极采集到的经络穴位信号,通过前置放大,将微弱的经穴信号高保真放大,并通过各种滤波电路滤除干扰,再经过采样变成数字信号在计算机中用MATLAB进行分析和处理。实验表明:该测量系统可明显检测到经络的良导性,该测量系统为经络信息的进一步研究打下良好的基础。

This paper presents a method to design a detection and processing system for meridian system. In the system, the amplification chips, i.e. AD620 and OP07 are used as the core components to obtain HI-FI pre-amplifieation. Thus, the very weak signals of the meridian points detected by the detecting electrodes can be amplified. Then, through the filtering circuit, the measuring noise will be suppressed. The filtered signals are sampled as the digital data which will be analyzed by using the Matlab software in the computer. The experimental results show that the good conductivity of the meridian points can be observed clearly. This system will provide a good foundation for further study of the meridian system.
