【摘要】：體域網(wǎng)作為遠(yuǎn)程監(jiān)護(hù)系統(tǒng)中的一種新技術(shù)，對(duì)緩解人們?nèi)找嬖鲩L(zhǎng)的醫(yī)療保健需求同傳統(tǒng)醫(yī)療資源不足的矛盾具有重大的社會(huì)意義。便攜式移動(dòng)網(wǎng)關(guān)作為連接體域網(wǎng)和互聯(lián)網(wǎng)的關(guān)鍵設(shè)備，可以讓用戶在移動(dòng)狀態(tài)下實(shí)現(xiàn)人體生理數(shù)據(jù)和環(huán)境數(shù)據(jù)的收集和轉(zhuǎn)發(fā)。因此，論文設(shè)計(jì)了一款基于Android智能手機(jī)的移動(dòng)網(wǎng)關(guān)，主要工作有： 1.完成了網(wǎng)關(guān)總體方案設(shè)計(jì)。論文將網(wǎng)關(guān)分成軟件界面、數(shù)據(jù)通信模塊、數(shù)據(jù)處理模塊以及文件管理模塊4部分，，并對(duì)各模塊的功能做了具體介紹。 2.完成了基于Android平臺(tái)的軟件界面設(shè)計(jì)。為了提高用戶體驗(yàn)和界面響應(yīng)速度，網(wǎng)關(guān)將復(fù)雜的數(shù)據(jù)處理工作放在后臺(tái)Service中執(zhí)行，界面只負(fù)責(zé)與用戶和測(cè)量設(shè)備的交互以及測(cè)量結(jié)果的實(shí)時(shí)顯示。 3.完成了數(shù)據(jù)通信模塊的設(shè)計(jì)。數(shù)據(jù)通信模塊包括藍(lán)牙通信子模塊和Wi-Fi通信子模塊兩部分。藍(lán)牙通信子模塊在實(shí)現(xiàn)點(diǎn)對(duì)點(diǎn)通信的基礎(chǔ)上，完成了網(wǎng)關(guān)與測(cè)量設(shè)備的組網(wǎng)；給出了一種通過(guò)Wi-Fi方式接入網(wǎng)絡(luò)，采用基于TCP/IP協(xié)議的Socket編程實(shí)現(xiàn)網(wǎng)關(guān)與服務(wù)器之間數(shù)據(jù)通信的方案。 4.完成了數(shù)據(jù)處理模塊的開(kāi)發(fā)。結(jié)合手機(jī)在處理器速度、內(nèi)存大小、散熱等方面的局限性，實(shí)現(xiàn)了心電、血壓、血氧飽和度以及脈搏等人體生理參數(shù)在網(wǎng)關(guān)中的處理以及實(shí)時(shí)顯示等功能。同時(shí)，網(wǎng)關(guān)采用定時(shí)更新基線和方差放大的處理方式解決了心電波形更新時(shí)的基線漂移。
[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.
