摘要
设计了一款基于FPGA的多功能生物电信号检测系统,通过更换不同的前置模拟盒对神经肌电信号、心电信号、表面肌电信号进行检测和分析。系统模拟电路与数字电路紧密结合,FPGA采用硬件电路与Nios嵌入式软件协同设计,实现了对生物电信号的采集、处理、存储、显示和分析。
A mutifunctional bioelectrical signal detecting system based on FPGA is presented in this paper. By altering the preprocessing box, it can detect and analyse the neural EMG signal, ECG signal and sEMG signal. By the way of integrating analog circuits with digital circuits, and cooperating hardware circuits with Nios II embedded software, this system realizes bioelectrical signal＇s collection, processing, storage, display and analysis.
