Design of ECG Acquisition System Using Adaptive Gain Control

论文以ECG信号峰峰值因测量者不同个体间差异为背景,介绍一种增益自适应ECG采集系统设计,使用AD603作为主放大器,以STM32F103ZET6作为核心处理器,实现了对ECG采集的自动增益控制,有效提高了系统对测量者个体差异的适应性,实际测试结果显示系统采集到的ECG数据满足医学诊断时的高精度、可靠性要求,具有一定的实用价值。

To adapt individual differences of ECG peak to peak value,an ECG acquisition system design using adaptive gain controlis is introduced in this paper.In this design,AD603 is used as the mainamplifierand and STM32F103ZET6 is used as the core processor.Finally it realizes the AGC acquisition of ECG,and the system effectively improve the adaptation of individual differences.The practical test results show that the ECG data collected by the system is precise and reliability when used in themedical diagnosis,and the system has certain practical value.
