【摘要】 随着对于自身健康的越来越关注,人们开始逐步注重了解日常的身体状况,希望能够及早的发现疾病所引起的一些身体基本指标的变化,从而达到在早期就对疾病进行治疗的目的。基于这一目标,越来越多的研究集中在健康监测领域。鉴于此,我们分析了目前国内相关领域的发展水平和未来的市场应用前景,提出了一种基于GSM/GPRS的嵌入式人体健康监测系统。整个系统由信号采集、控制、显示及发送单元组成。我们选取心电信号这一典型信号作为基本指标,在对心电信号进行分析和研究的基础上,设计了心电信号采集电路,该电路能较好的实现对心电信号的采集,同时对于心电信号所携带的典型干扰信号有较强的抑制能力。控制单元选用Samsung公司的ARM微控制器S3C44BOX,该微控制器是Samsung公司设计的一款低功耗高性能的、基于ARM7TDMI以及精简指令集的32位高速处理器,采用0.25umCMOS工艺制造,特别适用于对成本敏感和功耗敏感的应用场合。通过对嵌入式操作系统uClinux以及图形界面MiniGUI的移植,使得该系统易于扩展并且具有良好的人机界面,易于使用者进行操作。此外,该系统还利用GSM/GPRS无线网络进行数据传输,可以做到数据的实时传输。本文首先介绍了人体健康监测的研究目的和意义,接下来分别对于心电信号的采集、嵌入式操作系统uClinux以及图形界面MiniGUI的移植分别进行了阐述,最后详细说明了基于GSM/GPRS网络进行无线数据传输的方法。

【Abstract】 Putting much emphasis on self-health, people pay more attention to their daily health situation, hoping to discover the changes of the health that caused by diseases. Then they can do some thing to treat the disease earlier. Base on this aim, more and more researches focus on the human health monitoring. Consider of this situation, after analyzing the domestic development in related fields at present and its application in future market, we puts forward a kind of embedded human health monitoring system based on GSM/GPRS.The whole system is made up of the units for sampling signal, the unit for controlling and the unit for displaying and transmitting. We choose the ECG(electrocardiogram) signal as the typical signal and design the ECG signal sampling circuit based on analyse about the ECG signal. This circuit performed well on the ECG signal sampling and can also reduce the influence of the noise signal.We chooses the ARM-based microprocessor S3C44B0X as the controlling unit which manufactured by the company of Samsung. This microprocessor is a high performance and low power consumption 32-bit high speed CPU based on ARM7TDMI core and RISC(Reduced Instruction Set Computing). For using the 0.25umCMOS standard cells, the microprocessor worked well at the field that need low power consumpution and cost.This system have a good human-machine interface to users by translating the embedded system uClinux and graph interface MiniGUI. More over, this system uses the GSM/GPRS wireless network to transmit ECG data and real-time data. This paper first introduces the purpose and meaning of monitoring human health, followed by the ECG signal’s sampling, the transplant of the embedded system uClinux and the graph-user-interface MiniGUI. Finally, we give the details of the wireless data transmission based on GSM/GPRS network.
