【摘要】：伴随我国经济水平发展以及人口老龄化的出现,医疗设备厂商纷纷推出不同家庭健康设备用于个人自测以及疾病预防。但是不同设备以及不同厂商之间存在连接方式以及数据格式的不兼容问题,容易造成数据孤岛,对家庭健康管理以及远程医疗中的数据采集造成了无形的阻碍。而与此同时,ISO/IEEE以及CEN等国际标准化组织已经提出了一种医疗设备数据采集传输规范,并已经在发达国家成功推行,国内已有相关科研机构和公司对该标准进行研究和推广。本文通过对最优化交换协议和康体佳设备规范协议的研究和分析,以及对益体康设备数据传输方式及数据包格式进行分析之后,设计了基于Android平台的数据采集应用。应用可以同时支持康体佳个人健康设备和益体康个人健康设备,同时对采集到的数据提供数据同步管理以及分析结果推送的功能。对于具有会话功能的康体佳设备,通过在Native层定义和实现有限状态机以及数据编解码器的方式,并在上层应用中提供统一的数据回调接口,实现了应用与康体佳设备的会话以及数据采集。而对于不包含会话状态机的益体康设备,通过构建动态加载框架,将蓝牙数据包的解析逻辑解耦并编译到单独的APK文件中,在执行时通过动态加载的方式提供对多厂商多设备的支持,同时通过复用康体佳设备的数据回调接口,保证宿主应用的不变性。对于采集到的数据,通过自签CA建立与服务器之间的安全链接并将数据自动同步到远程数据中心,有效保护了用户的信息安全以及数据的可信度。远程数据中心在通过对用户数据的建模和分析后,通过与应用之间的长连接将相关信息返回给用户。经过测试,系统实现了对康体佳认证的血压体重等设备的支持,以及对益体康的血压计和血糖仪的支持,实现了多厂商多设备的兼容。两类设备中会话模块以及数据解析模块都独立于上层应用,因此具有一定的可扩展性。在应用稳定性以及数据推送方面,也达到了测试要求。测试结果表明系统达到预期设计目标。
[Abstract]:With the development of economic level and the aging of population in China, medical equipment manufacturers have introduced different family health equipment for personal self-testing and disease prevention. However, there are some incompatibility problems between different equipments and manufacturers, such as the incompatibility of data format, which can easily lead to isolated data island, which is an invisible obstacle to family health management and data collection in telemedicine. At the same time ISO / IEEE and CEN and other international standardization organizations have proposed a standard for data collection and transmission of medical equipment which has been successfully implemented in developed countries and has been researched and popularized by relevant research institutions and companies in China. Based on the research and analysis of the optimized exchange protocol and the standard protocol of the equipment, as well as the analysis of the data transmission mode and the data packet format of the equipment, a data acquisition application based on the Android platform is designed in this paper. The application can support both the health equipment and the personal health equipment. It also provides the function of data synchronization management and the push of analysis results to the collected data. For the recreational and sports equipment with session function, the finite state machine and data codec are defined and implemented in the Native layer, and the unified data callback interface is provided in the upper application. It realizes the conversation and data acquisition between the application and the sports equipment. For the Yixukang device without session state machine, the parsing logic of Bluetooth packet is decoupled and compiled into a separate APK file by constructing a dynamic loading framework. At the same time, it provides support for multi-vendor and multi-device through dynamic loading, and ensures the invariance of host application by multiplexing the data callback interface of Kangzhou-best equipment. For the collected data, the security link between the server and the self-signed CA is established and the data is automatically synchronized to the remote data center, which effectively protects the information security of the user and the credibility of the data. After modeling and analyzing the user data, the remote data center returns the relevant information to the user through the long connection with the application. After testing, the system realizes the support of the equipment, such as blood pressure and body weight, as well as the sphygmomanometer and the blood sugar meter, and realizes the compatibility of multi-manufacturer and multi-equipment. Both the session module and the data parsing module are independent of the upper application, so they are extensible. In terms of application stability and data push, it also meets the test requirements. The test results show that the system achieves the desired design goal.
