基于Android的便携式心电监护系统设计

Portable Ecg Monitoring System Design Based on Android Platform

利用Matlab处理心电信号的传统方式不能实现数据的实时处理与健康状况的及时诊断,且携带不方便,针对这种情况,提出了基于Android平台的便携式心电实时监护系统的设计方法。系统首先通过蓝牙4.0接收实时心电数据,然后利用心电数字滤波算法滤除干扰信号,绘制出较为理想的实时波形,最后通过心电诊断算法返回检测一段时间后的诊断信息,同时将压缩数据传输给医院服务器,以便医生通过聊天功能及时与用户进行交流。实验结果表明,本系统滤波效果良好,返回诊断结果准确,实现了与在Matlab上一样的处理效果。

The traditional way of using Matlab processes ecg signals can not achieve real-time processingof data ,timely diagnosis of symptoms, and carrys not convenient. In view of this, we propose a designmethod that based on the Android platform of the portable ecg real-time monitoring system. System firstreceive the real- time ecg data via bluetooth 4.0, then using ecg digital filtering algorithm filtersinterference signal, map the ideal real-time waveform, Finally back to Diagnostic information by ecgdiagnosis algorithm after a period of time , transfer the compressed data to the hospital server, so that thedoctor can communicate with users timely through the chat function. Experimental results show that thesystem filtering effect is good, return to diagnosis results are accurate, Achieved with the same treatmenteffect on Matlab.
