基于FPGA的ECG信号采集与处理系统设计

摘要

当今平板电脑和大屏幕智能手机的普及为便携式心电监护仪的发展带来了机遇。针对这种发展趋势，设计了便携式心电（electrocardiogram，ECG）信号的实时采集、处理和传送系统。该系统以FPGA为控制中心，用高精度24位心电专用芯片实现模数转换，用FIR滤波算法实现高阶数字滤波。该系统采集和处理的ECG数据可传送至平板电脑或大屏幕智能手机，以方便心脏疾病者自我初步诊断。%This paper designs a portable ECG signal real-time acquisition, processing and transmission system, The System consists of special ECG analog to digital conversion chip which has 24-bit of high precision in order to FIR filter algorithm for high order digital filter based on FPGA. The system of collecting and processing ECG data can be transmitted to the tablet computer or big screen smart mobile phone to facilitate their initial diagnosis of heart disease. The system is a portable and cost-effective, and has perfect filtering effect.
