Abstract: To provide a more effective method for the visualization of the meridian, applying the host-slave machine to design a multi-
channel meridian locating and imaging system. The meridian detector uses the rheostat to balance the 16 channel system parameters, for the meridian electrical impedance getting from the host machine and the three-dimensional-coordiante acquired from the slave machine, the multi-threading technology of operating system is used to match these two signals, and the cost function is introduced to select the accurate meridian location through two different angles. The experimental results show that the system can make the detection error of the impedance be less than 0.2%, remove interference from the system, and extract the accurate meridian channel.

Key words: meridian, multi-channel impedance detecting, host-slave machine, locating and imaging

摘要： 为给经络可视化研究提供更有效的工具，基于上下位机工作模式设计了一套多通道经络定位与成像系统。采用电位器平衡16通道经络检测仪的系统参数，对上位机采集到的经络电阻抗数据和下位机获得的三维坐标信息，利用操作系统的多线程技术进行匹配，并引入代价函数的方法，从两个不同的角度确定出准确的经络点位置。实验结果表明，用该检测系统采集到的经络电阻抗最大误差不超过0.2%，并能去掉检测系统中出现的多个干扰点，提高了系统的检测精度。
