摘要
设计了一款便携式低功耗的动态心电图系统,并通过蓝牙模块完成动态心电图在Android端的实时显示。该系统由STM32L152微处理器、HHW_USART_S10蓝牙模块以及电源管理单元等分离元件构成,并在心电系统内部首次使用低功耗模拟前端集成芯片完成7导联动态心电图的采集,实时反映心脏活动的变化。该系统的供电电压为1.8 V,且工作时的功耗仅为40 m W。Android端的动态心电图显示软件适用于Android2.2以上版本的操作系统。
This paper aims at designing a low-power portable holter system, and completing holter display by the Bluetooth module in real time on android system. The system is composed by STM32lL52 microprocessor, HHW_USART_S10 Bluetooth module, power management unit and other discrete components. And the analog front-end low power integrated chip that the first application within the ECG system is used to complete the seven-lead holter collection and to reflect the change cardiac activity in real time. The power supply of the system is 1.8 V and the power consumption is 40 mW at work. The dynamic ECG display software based on android is suitable for the Android version 2.2 above.
