【摘要】：健康,是亙古以來人類除了生存以外所考慮的問題之一。由于古代的醫(yī)療條件落后,所以由疾病引發(fā)的死亡是造成人口減少的主要原因,因而如何預(yù)防疾病也就逐漸被人類所重視。隨著人們的物質(zhì)水平逐漸提高,人們不僅僅關(guān)注精神方面的需求,更對(duì)自己的健康狀態(tài)要求逐漸提升。由于我國的人口基本國情表現(xiàn)為低出生率與高老齡化的兩極分化以及亞健康人群數(shù)量增長的趨勢,所以對(duì)健康醫(yī)療監(jiān)測系統(tǒng)的研究設(shè)計(jì)也是社會(huì)需求的結(jié)果。 本文重點(diǎn)介紹了一種基于無線多參數(shù)人體健康監(jiān)護(hù)系統(tǒng)中的血壓監(jiān)測系統(tǒng)的設(shè)計(jì)。該監(jiān)測系統(tǒng)主要包括信息采集模塊、數(shù)據(jù)處理模塊和ZigBee傳輸模塊,信息采集模塊完成人體生理參數(shù)血壓的采集并在數(shù)據(jù)處理模塊部分進(jìn)行計(jì)算,采用ZigBee傳輸模式將信號(hào)數(shù)據(jù)送至數(shù)據(jù)中心模塊,最后在中心模塊完成與其他生理參數(shù)信號(hào)的融合處理并通過局域網(wǎng)網(wǎng)絡(luò)上傳至醫(yī)療監(jiān)控中心方便專家查閱診斷。本論文重點(diǎn)介紹血壓信號(hào)采集模塊的原理、電路硬件設(shè)計(jì)及其軟件設(shè)計(jì)。采集模塊的硬件電路包含外接電路、氣動(dòng)電路以及驅(qū)動(dòng)電路,這部分電路完成血壓的前期采集,通過壓力傳感器轉(zhuǎn)換為電信號(hào),并通過信號(hào)提取電路進(jìn)行濾波和運(yùn)放送至控制芯片的A/D轉(zhuǎn)換得到相應(yīng)的靜壓信號(hào)和脈搏信號(hào),最后通過軟件計(jì)算最終得出我們需要的平均壓、收縮壓和舒張壓以及脈搏值。 系統(tǒng)采用IT公司的MSP430FG149低功耗芯片,設(shè)計(jì)了無線血壓監(jiān)護(hù)系統(tǒng),使其具有功耗低、體積小、存儲(chǔ)容量大和處理速度高等特點(diǎn),采集模塊與ZigBee發(fā)射接收模塊相連,可以實(shí)現(xiàn)血壓生理信號(hào)的監(jiān)測和無線傳輸,使得人體健康狀況無線血壓監(jiān)測到實(shí)時(shí)監(jiān)控成為一種可能。
[Abstract]:Health has been one of the problems that human beings have considered in addition to survival since ancient times. Because of the backward medical conditions in ancient times, the death caused by disease is the main cause of population decline, so how to prevent disease is gradually paid attention to by human beings. With the improvement of people's material level, people pay more attention not only to their spiritual needs, but also to their state of health. Because of the polarization of low birth rate and high aging population and the increasing trend of the number of sub-healthy population in China, the research and design of health medical monitoring system is also the result of social demand. This paper focuses on the design of a blood pressure monitoring system based on wireless multi-parameter human health monitoring system. The monitoring system mainly includes information acquisition module, data processing module and ZigBee transmission module. The information acquisition module completes the blood pressure collection of human physiological parameters and calculates in the data processing module. The signal data is sent to the data center module by ZigBee transmission mode. Finally, the signal fusion with other physiological parameters is completed in the center module and uploaded to the medical monitoring center through the LAN network to facilitate experts to consult the diagnosis. This paper focuses on the principle of blood pressure signal acquisition module, circuit hardware design and software design. The hardware circuit of the acquisition module includes external circuit, pneumatic circuit and drive circuit. The signal extraction circuit is used to filter and transport to the control chip A / D conversion to obtain the corresponding static pressure signal and pulse signal. Finally, the average pressure, systolic pressure, diastolic pressure and pulse value we need are obtained by software calculation. The system adopts MSP430FG149 low power chip of IT company, designs wireless blood pressure monitoring system, which has the characteristics of low power consumption, small volume, large storage capacity and high processing speed. The acquisition module is connected with the ZigBee transmitting and receiving module. It can realize the monitoring and wireless transmission of blood pressure physiological signals, which makes it possible to monitor human health status by wireless blood pressure monitoring in real time.
