This system mainly contains the front-end pulse interception and back-end software analysis. In the first part, we used a non-invasive infrared measurement method based on the dual channel simultaneous measurement technique. We measured the photo-plethysmograph from the subject's fingers and toes simultaneously, then used an analog circuit and central control unit to process the signals. Finally, the digital volume pulse data is processed by a personal computer. Because the characteristic points of digital volume pulse always occur in sharp variations, this paper proposes two algorithms to solve this problem. First, we find the pacemaker and percussion wave peak from transient slope variation, and then locate the dicrotic notch and dicrotic wave peak by using the wavelet transformation algorithm. When we analyze the data, we use the Visual Basic graphical user interface, which together with the Matlab is the core of the system.

本系统主要包含前端脉波撷取及后端软体分析两部分，其中前端脉波撷取部份是以非侵入式的红外线量测方式，双通道同步量测受测者手指与脚趾的光容积变化描记图，同时将此讯号经类比处理电路及中央控制单元输出成为数位容积波，再传送至个人电脑中；而在后端软体分析部份，因数位容积波之特徵点皆出现於波形中急剧变化的部份，故本论文以瞬间斜率变化量来定位脉波讯号中的起搏点及主波峰顶点，并利用小波转换演算法（wavelet transformation algorithm）来分析重搏切迹与重搏波顶点；程式撰写主要以Matlab为核心，结合Visual Basic的图形化使用者操作介面，增加系统与使用者间的亲和力。

In the course of the impulse through underground mediator, because the physical property and the geometric property of mediator is non-uniform, wave form and wave amplitude will change very much and the impulse after shock、antenna direction figure、the couple degree of ground surface、system interfere、non-uniform of the underground mediator、reflection surface's rough cause the disturb of radiation scatter and diffract will complex the figure .

脉冲在通过地下介质的过程中，由于介质的物性和几何性质的不均一性，波形和波幅将发生较大的变化，而脉冲余振、天线方向图形、天线的地表偶合程度、系统内部的干扰、地下介质的不均匀、反射面不光滑等引起的辐射效率、散射的变化以及剖面旁侧的绕射等干扰，均使实时记录图像复杂化。

For the models by MMFI is a nonlinear differential equation with variable coefficients and the 'nonlinearity' brings discommodiousness to analyse the nature and quantification of a control system, it applies brim linearization method to better MMFI. By transforming 'triangle wave' membership functions of the base elements into 'rectangle wave' membership functions, we get three models which represent different aspect respectively. By simulating second order system and analysing the errors of the results, a conclusion is drawn, that is, the model obtained by brim linearization method has a good precision in contrast with the real model.

由于模糊推理建模法得到的模型是变系数非线性微分方程，这种&非线性&对该控制系统的某些定性或定量分析带来不便，因此应用边缘线性化方法对模糊推理建模法进行改进，将基元的隶属函数由&三角波&改成&矩形波&，从而得到了三个模型，这三个模型各有侧重，通过对二阶系统进行仿真，分析仿真结果，从而给出了关于边缘线性化方法的结论，即由边缘线性化方法得到的系统模型对该系统的真实模型有较高的逼近精度。
