【摘要】：体域网作为远程监护系统中的一种新技术，对缓解人们日益增长的医疗保健需求同传统医疗资源不足的矛盾具有重大的社会意义。便携式移动网关作为连接体域网和互联网的关键设备，可以让用户在移动状态下实现人体生理数据和环境数据的收集和转发。因此，论文设计了一款基于Android智能手机的移动网关，主要工作有： 1.完成了网关总体方案设计。论文将网关分成软件界面、数据通信模块、数据处理模块以及文件管理模块4部分，，并对各模块的功能做了具体介绍。 2.完成了基于Android平台的软件界面设计。为了提高用户体验和界面响应速度，网关将复杂的数据处理工作放在后台Service中执行，界面只负责与用户和测量设备的交互以及测量结果的实时显示。 3.完成了数据通信模块的设计。数据通信模块包括蓝牙通信子模块和Wi-Fi通信子模块两部分。蓝牙通信子模块在实现点对点通信的基础上，完成了网关与测量设备的组网；给出了一种通过Wi-Fi方式接入网络，采用基于TCP/IP协议的Socket编程实现网关与服务器之间数据通信的方案。 4.完成了数据处理模块的开发。结合手机在处理器速度、内存大小、散热等方面的局限性，实现了心电、血压、血氧饱和度以及脉搏等人体生理参数在网关中的处理以及实时显示等功能。同时，网关采用定时更新基线和方差放大的处理方式解决了心电波形更新时的基线漂移。
[Abstract]:As a new technology in remote monitoring system, body area network has great social significance to alleviate the contradiction between the increasing demand of medical care and the shortage of traditional medical resources. As a key device to connect body area network and Internet, portable mobile gateway enables users to collect and transmit human physiological data and environmental data in mobile state. Therefore, this paper designs a mobile gateway based on Android smart phone, the main work is as follows: 1. The overall scheme design of the gateway is completed. The gateway is divided into four parts: software interface, data communication module, data processing module and file management module. 2. The software interface design based on Android platform is completed. In order to improve the user experience and interface response speed, the gateway performs complex data processing work in the background Service. The interface is only responsible for the interaction with the user and the measuring device and the real-time display of the measurement results. 3. The design of data communication module is completed. The data communication module includes two parts: Bluetooth communication sub-module and Wi-Fi communication sub-module. On the basis of the point-to-point communication, the Bluetooth communication sub-module completes the networking between the gateway and the measuring equipment. This paper presents a scheme of data communication between gateway and server using Socket programming based on TCP/IP protocol, which is connected to network by Wi-Fi. 4. The development of data processing module is completed. Combined with the limitation of the mobile phone in processor speed, memory size and heat dissipation, the functions of ECG, blood pressure, blood oxygen saturation, pulse and other human physiological parameters in the gateway are processed and displayed in real time. At the same time, the gateway solves the baseline drift when ECG waveform is updated by timing updating baseline and variance amplification.
