【摘要】：在医疗监护系统中,体温、血压和脉搏3个生理参数是人体最重要、最基本的生命体征。如何能自动、及时、准确完成对这些参数的监测,并且实现数据的无线传输成为当前研究的热点。本文针对嵌入式系统体积小、功能强大、成本低廉等优势,智能手机日益普及,Internet高速发展,将物联网的概念应用于医疗监护系统,提出了eHealthCare系统,并完成了系统下健康伴侣的设计与实现。本文的选题对医疗事业有着深远的意义,随着我国经济的快速发展,人民的生活水平有了极大的提高,但经济的发展使得社会的竞争愈加激烈,工作和生活节奏的加快,压力的与日俱增,使人们无暇关注自己的身体健康,久而久之自身的身体健康状况不断下降,身体开始出现各种各样的问题,这种情况在大城市尤为明显。人们开始对自身健康问题的关注,希望通过更加方便,更加快捷的方法去了解自身的身体状况,同样,医务工作者也希望通过简单的方法来获得病人的生理参数,以便及时观察病人健康状况的变化。因此,研究出一套在家就能自动、准确完成对人体生理参数的监测,并能将数据发送给远程的医疗信息系统,使医务工作者能够及时获取第一手的资料和数据的医疗监护系统显得意义重大。 eHealthCare系统利用物联网这一新颖概念将便携式医疗设备、用户手机和医疗信息系统联系在一起,实现了便携式医疗设备的无线化,网络化和远程化。健康伴侣就是一台基于嵌入式的便携式家用医疗设备,在研究与设计前对市场上存在的以电子血压计为主的各类医疗检测设备进行了充分的调查与分析,针对存在的不足提出了健康伴侣的设计方案,健康伴侣实现的主要功能包括多参数测量,LCD显示,蓝牙无线发送,除此之外,还要满足体积小,功耗低,成本低,安全性高等特点。为了实现以上功能,本系统采用了高性能的AVR微控制器为核心进行设计,实现对测量过程的自动控制与调节；采用飞思卡尔半导体公司研制的压力传感器MPX2050GP完成血压信号的数据采集,采用DALLAS公司生产的单线数字温度传感器DS18B20完成体温信号的数据采集；利用AD620组成的直流放大电路及OPA277构成的带通滤波网络提取信号；使用微控制器内部集成的10位逐次比较模数转换器实现对数据的转换；所有数据测量完毕后可以在LCD显示屏自动显示；系统还加入蓝牙模块,实现数据的无线发送功能。最后,本文对本系统的研究和设计进行了总结,并提出了改进措施及下一步的工作,相信对未来医疗监护设备的进一步研究具有一定的指导意义。
[Abstract]:In the medical monitoring system, three physiological parameters, body temperature, blood pressure and pulse, are the most important and basic vital signs of the human body. This paper aims at the advantages of small size, powerful function and low cost of embedded system. The concept of Internet of things is applied to the medical monitoring system, and the eHealthCare system is proposed, and the design and implementation of the healthy partner under the system is completed. With the rapid development of our economy, the living standards of the people have been greatly improved, but the economic development has made the social competition more intense, and the pace of work and life has accelerated. With the increasing pressure, people have no time to pay attention to their own health. Over time, their own health condition is declining, and the body begins to appear various problems. This is especially true in big cities. People are beginning to pay attention to their own health problems, hoping to understand their physical condition in a more convenient and faster way. Medical workers also hope to obtain the patient's physiological parameters through a simple method in order to observe the changes in the patient's health status in time. Therefore, to develop a set of automatic and accurate monitoring of human physiological parameters at home, It is of great significance to send the data to the remote medical information system, so that the medical workers can get the first-hand information and data in time. EHealthCare system uses the novel concept of Internet of things to connect portable medical equipment, user's mobile phone and medical information system together, and realizes the wireless, network and remote of portable medical device. The health partner is a portable medical device based on embedded system. Before the research and design, we have made a thorough investigation and analysis of all kinds of medical testing equipment, which is mainly electronic sphygmomanometer in the market. The main functions of the health partner include multi-parameter measurement LCD display, Bluetooth wireless transmission, in addition to small size, low power consumption and low cost. High safety features. In order to realize the above functions, the system adopts the high-performance AVR microcontroller as the core to realize the automatic control and adjustment of the measurement process. The pressure sensor MPX2050GP developed by Freescale Semiconductor Company is used to complete the data acquisition of blood pressure signal, and the single line digital temperature sensor DS18B20 produced by DALLAS Company is used to complete the data acquisition of body temperature signal. The DC amplifier circuit composed of AD620 and the band-pass filter network composed of OPA277 are used to extract the signal, and the data conversion is realized by the 10-bit successive analog-to-digital converter integrated in the microcontroller. All the data can be automatically displayed on LCD display screen, and Bluetooth module is added to the system to realize wireless data transmission. Finally, this paper summarizes the research and design of the system, and puts forward the improvement measures and the next step, which is believed to be of certain guiding significance to the further study of medical monitoring equipment in the future.
