基于安卓4.3的移动心电监护系统设计

Design of the Mobile ECG Monitoring System Based on Android 4.3

为了实现对心电信号24 h跟踪监护和记录,设计了一套基于安卓4.3的移动心电监护系统。该系统采用复旦大学自主研发的E9622A作为模拟前端芯片采集心电信号,选取TI公司的蓝牙低功耗片上系统CC2541与手机进行通信,在安卓平台上对心电信号进行处理并显示。整个系统集成在一块2 cm×2 cm的PCB上。实验表明,该系统穿戴在人体上可以有效采集心电信号并在客户端实时显示清晰波形和基本心电参数,可用于心律失常的初步判断,且具有低成本、低功耗、灵活性强和携带方便的特点。

To monitor and record Electrocardiograph （ECG） signals for 24 hours, a mobile ECG monitoring system is designed based on Android 4.3. In this system, domestic indigenous E9622A is used to acquire ECG signals and TI CC2541 is adopted to communicate with mobile phones. The program is implemented on the Android platform to display and process ECG signals. The whole system is integrated on a 2 cm＆#215;2 cm PCB. From experiments, it is shown that ECG signals can be obtained effectively when this system is worn, and clear ECG waveforms and parameters can be shown on the phones. With this system, arrhythmia can be diagnosed preliminarily. It is also shown that the system is low-power, low-cost, flexible and portable.
