摘 要随着科技的发展和社会的进步，人们的生活环境也发生了大幅度的变化，各类疾病随着各种污染源的出现而产生，对我们的健康造成了巨大的侵害。特别是近年来流感病毒的传播和心脑血管疾病的发病率变高受到了全球的高度关注。计算机渐渐进入家庭，为研究开发具有处理、分析和存储能力的家庭医疗监护系统提供了可行的基础。为了监测疾病和提高预防的水平，对常见病、慢性病进行实时监测，本课题设计了一种监测系统和家庭医疗护理，可以在家里更方便、更快捷地实行对体温信号、心电信号和脉搏信号的监测，并且能对采集的信号进行合理的分析、存储和显示。

整个系统包括放大电路模块、传感器模块、DAQ数据采集模块和PC机软件编程几个部分。分别通过温度传感器和心电传感器进行体温信号和心电信号的采集，经过模拟的电路处理，再将已经处理过的信号送到数据采集卡输进电脑，最后利用LabVIEW编程，对体温信号进行标度变换、从心电信号中分离脉搏信号。实现各类信号时域和频域的分析和数据的存储，最后把处理和分析的数据通过界面显示出来。78208

Multifunctional Household Medicaldetection System   based on LabVIEW 

Abstract With the development of science and technology and the progress of society, people's living environment has also changed a great range, all kinds of diseases with the emergence of a variety of pollution sources, resulting in our health caused great damage。 Especially in recent years, the spread of influenza viruses and the incidence of cardiovascular and cerebrovascular diseases have become highly concerned about the global。 The computer is gradually entering the family, which provides a feasible basis for the research and development of the family medical monitoring system which has the ability of processing, analysis and storage。 In order to improve the level of preventing disease surveillance and, for common diseases and chronic diseases of real-time monitoring, this project design a monitoring system and home health care, can be at home more convenient and more quickly implement the monitoring of temperature signals, ECG signals and pulse signals, and to rational analysis, storage and display of signal acquisition

The whole system consists of amplifier circuit module, sensor module, DAQ data acquisition module and PC software programming。 Respectively by ECG and temperature sensor for temperature signal and ECG signal acquisition, processed by circuit simulation, again will have already processed the signal sent to the data acquisition card into the computer。 Finally, using LabVIEW programming, scale transformation, from the ECG signal separation pulse signal of temperature signal。 The realization of various types of signals in the time and frequency domain analysis and data storage, and finally the processing and analysis of the data through the interface display。
