基于Android的手持式心电检测系统设计

摘要

设计了一种基于Android平台的手持式心电(ECG)检测系统,其终端产品以小型、低功耗为目标.本文设计了两种心电信号采集方式,一是采用BMD101心电芯片,通过左右手手指分别触摸金属电极实现心电信号的快速采集和实时显示;二是设计了一种单通道、三导联的导联线采集方式,可以长时间精确采集心电信号并实时显示.系统还包括相应的手机APP,手持式心电检测仪通过蓝牙将数据传输给手机APP,方便使用者实时查看,以及医患交流.%A handheld ECG detection system based on Android platform is designed,which terminal products trend to small,low power consumption.This system with two kinds of ECG signal acquisition methods are degined,one is the use of BMD101 chip,through the left and right fingers touch metal electrodes to realize the fast acquisition and real time display of ECG signal.The second is to design a single channel,three-lead gurdline acquisition method,can be a long time accurate acquisition of EGG signals and real-time display.The system also includes the corresponding APP,the portable ECG monitor transmits data to the mobile phone though Bluetooth,so that facilitate users can view in real-time and communicate with doctors and patients.
