摘　　要：为提高便携式心电监护设备的信号采集功能、改善单导联信号采集造成的疾病诊断不全现象,该研究通过采用STM32L433CBT6微处理器控制前端模拟芯片ADS1293采集三导联心电信号,并根据用户需求选择ZigBee、WIFI或NB-IOT三种方式进行心电信号的无线传输,利用低功耗器件、优化软件程序、设置低功耗模式等方式降低系统功耗,设计出一款具有体积小(6.5 cm×4 cm×2 cm)、功耗低(WIFI:122 mW、ZigBee:43 mW、NB-IOT:34 mW)、便携等优点的新型心电信号采集系统,从而实现长时间稳定的心电信号检测。In order to improve the signal acquisition function of portable ECG monitoring equipment and improve the phenomenon of incomplete disease diagnosis caused by single-lead signal acquisition,this study uses STM32L433CBT6 microprocessor to control the front-end analog chip ADS1293 to collect three-lead ECG signals,and selects ZigBee,WIFI or NB-IOT three ways for wireless transmission of ECG signals according to user needs.It uses low-power devices,optimizes software programs,and sets lowpower modes to reduce system power consumption.A new ECG signal acquisition system with small size(6.5 cm×4 cm×2 cm),low power consumption(WIFI:122 mW,ZigBee:43 mW,NB-IOT:34 mW)and portability is designed to realize long-term stable ECG signal detection.
