摘要

在本文中，我们设计了一个基于usb的数据采集系统来记录肌电信号。所有实验均在皮肤表层(角质层)设置3个凝胶化银/氯化银(Ag/AgCl)电极。低电平电压(μV到mV)的原始信号通过低功耗放大器进行处理和滤波。采用基于8051工业核心的AN2131QC单片机对模拟信号进行数字化处理。数据立即通过USB连接发送到笔记本电脑上。然后，围绕MATLAB软件构建一些处理工具，对数据进行相应肌电信号的时间和频率表征。

A USB based data acquisition system for EMG signal recording

In the present paper, we present the design of a USB-based data acquisition system to record Electromyogram signal (EMG). Three gelled Silver/Silver chloride (Ag/AgCl) electrodes were set on the upper layer of the skin surface (stratum corneum) in all the conducted experiments. The raw signal which is a low level voltage (μV to mV) is processed and filtered by a low-power consumption amphfier. The analog signal was digitized by an AN2131QC QC microcontroller kit based on the 8051 industrial core. The data were instantly sent to a laptop through a USB link. Then, some processing tools were built around MATLAB software and were applied to the data for temporal and frequenciel representation of the corresponding electromyogram signal.
