【摘要】：近年来慢性病发病率和发病人数的不断攀升,人们越来越关心自身的健康问题,健康观念也从重视病后治疗恢复逐渐转向病前及时预防诊断,以追求更健康的生活方式。伴随着各种智能技术在医疗领域的应用和互联网的快速发展,尤其是生理指标采集设备的普及,为慢性病的监控管理提供了可能。论文以ARM920T的S3C2440A为核心处理器,搭建嵌入式Linux软硬件开发平台,采用多线程执行基于TCP/IP协议的Socket套接字实现网络通信,通过Mysql数据库进行数据存储,设计并实现了集健康参数采集、监测管理、风险预测、专家建议、信息管理等功能为一体的健康监测系统。论文主要研究内容如下:首先,基于系统的设计要求,给出了系统总体方案,包括测量数据采集、通信网关数据封装传输、系统应用管理三个部分。其中测量数据采集分为生理指标和用户身份两种数据,分别通过专业设备采集后经串口或USB接口传输到通信网关,由通信网关进行数据转换和封装后上传数据,用户在一体机上的健康监测管理系统查看测量结果、风险预测结果、个人档案等信息,由服务器的数据库存储数据,管理员可通过WEB远程登录管理系统进行查看用户数据和系统维护。其次,依据系统的总体方案和硬件结构方案进行了系统硬件详细设计,主要包括通信网关的外围电路如音频、功放、网络、电源、串口等模块。音频模块和功放模块分别采用UDA1341TS声卡芯片和SGM4871音频功放芯片,连接扬声器播放语音提示;网络模块采用DM9000CE以太网芯片,搭配带网络变压器HR911105A的RJ45接口,实现网络连接;采用LM1117稳压芯片和DC/DC隔离保证电路稳定的工作电压;采用MAX3232进行电平转换后,再经过9针串口接口和USB接口实现数据传输。最后,根据搭建的硬件开发平台,移植并搭建嵌入式Linux软件开发环境。运用C开发语言进行多线程和Socket编程,实现通信网关的系统初始化、数据收发、封装传输、播放语音提示、检测网络连接等功能;运用JAVA开发语言实现监控系统通信等功能;并给出了系统数据库的设计,对系统进行了测试。经过运行测试,系统实现了生理指标的采集、检测和查询,通过历史记录和测量数据分析实现慢性病的评级、预警,并提供相应的专家建议和防控知识,生成个人电子档案便于保存,实现了健康监测系统的基本功能,达到了预期效果。系统拆分功能按模块进行设计,便于系统升级、维护和裁剪扩展,可应用于体检中心、社区医院、基层康复中心、养老院等机构。
[Abstract]:In recent years, with the increasing incidence and number of chronic diseases, people are more and more concerned about their own health problems. The concept of health has gradually shifted from paying attention to the recovery of post-illness treatment to timely prevention and diagnosis before illness, in order to pursue a healthier lifestyle. With the application of various intelligent technologies in the medical field and the rapid development of the Internet, especially the popularization of physiological index collection equipment, it is possible to monitor and manage chronic diseases. This paper takes ARM920T S3C2440A as the core processor, builds the embedded Linux software and hardware development platform, uses the multi-thread to execute the socket based on TCP / IP protocol to realize the network communication, and carries on the data storage through the MySQL database. A health monitoring system is designed and implemented with the functions of health parameter collection, monitoring and management, risk forecasting, expert advice, information management and so on. The main contents of this paper are as follows: firstly, based on the design requirements of the system, the overall scheme of the system is presented, including measurement data acquisition, communication gateway data encapsulation and transmission, and system application management. The measurement data collection is divided into physiological index and user identity data, which are transmitted to the communication gateway through serial port or USB interface after the collection of professional equipment, and the data are transferred and encapsulated by the communication gateway. The user's health monitoring and management system on an integrated computer looks at the results of measurement, risk prediction, personal files and other information, and stores data by the database of the server. Administrator can view user data and system maintenance through Web remote login management system. Secondly, according to the overall scheme of the system and the hardware structure of the system, the detailed design of the system hardware, including the communication gateway peripheral circuits such as audio, power amplifier, network, power supply, serial port and other modules. The audio module and the power amplifier module adopt UDA1341TS sound card chip and SGM4871 audio power amplifier chip respectively to connect loudspeaker to play voice prompt, the network module adopts DM9000CE Ethernet chip and RJ45 interface with network transformer HR911105A to realize network connection. LM1117 voltage regulator chip and DC / DC isolation are used to ensure the stable working voltage of the circuit, and after the level conversion is carried out by MAX3232, the data transmission is realized through 9-pin serial port interface and USB interface. Finally, according to the hardware development platform, the embedded Linux software development environment is transplanted and built. C programming language is used for multithreading and socket programming to realize the functions of system initialization, data receiving and sending, encapsulation and transmission, voice prompt playing, network connection detection and so on, and the communication function of monitoring system is realized by Java development language. The design of the system database is given, and the system is tested. After running and testing, the system realizes the collection, detection and query of physiological indexes, the classification and early warning of chronic diseases through the analysis of historical records and measured data, and provides the corresponding expert advice and knowledge of prevention and control. The basic function of the health monitoring system is realized and the expected effect is achieved. The system split function is designed according to the module, which is convenient for system upgrade, maintenance and cutting expansion, and can be applied to medical examination center, community hospital, primary rehabilitation center, nursing home and so on.
