2、疾病的预防和诊治提供了极大的帮助。 为了使人们可以及时且便捷的了解到自身的心电状况,本文基于 Android 操作系统 设计了基于智能手机平台的移动心电监护系统。该系统通过三导联系统采集用户的心电 数据,并通过放大电路和单片机实现信号放大和模拟信号数字化。智能手机通过蓝牙与 硬件连接完成数据传输,通过智能手机 SOC 实现对数据的滤波去噪处理以及相关的检 测。最后通过应用程序反馈用户的心电数据及诊断结果。应用程序实现了对心电数据的 动态绘制,使用户能够更直观的了解心电数据。 在硬件方面使用低通和高通 2 级滤波并对信号放大。 放大后的信号通过 ATmega128 单片机实现对数据的转换(采样频
3、率为 200Hz)。软件方面,借助 MATLAB 对信号做 低通滤波去工频干扰。对比了中值滤波与小波变换去基线漂移的效果。完成了 QRS 波 的特征提取。最后通过 Eclipse 完成对程序的移植并实现了在真机华为荣耀 6 上运行。 关键词:移动医疗;心电监护;Android 操作系统;特征提取;滤波;蓝牙 基于智能手机的人体信息检测分析技术研究 - II - The Study of Detection and Analysis Technology of the Human Information Based on the Smartphone Abstract In recent yea
4、rs, with the rapid development of smartphone SOC and the rapid adoption of smart phones, Mobile medical equipment has also been explosive growth. By combining with smartphone, Mobile medical provides a special way to promote health care. Moreover, the establishment of the system is very easy and low
5、 cost. It can help people know their own health in time, and it is helpful to provide for prevention and treatment of diseases. In order to make it timely and convenient for people to learn their ECG status, This paper designs a mobile ECG monitoring system based on smart phone platform and Android
6、operating system. The system collects user ECG data by the three lead, and to achieve signal amplification and analog to digital conversion by an amplifier circuit and microcontroller. Hardware connected to smart phone by Bluetooth to transport data. It removes noise and completes the relevant detections by smartphone SOC. Finally, It feedback data and results to user by the application. Application can dynamic draw ECG data and user can know them more intuitively. We use low-pass and high-
