摘　　要：论文实现了一种便携式多通道数据采集系统,配合单片机固件及上位机应用软件,系统能够实时采集外界模拟信号并转换为相应的数字信号,通过USB总线传送到上位机应用软件,通过滤波、傅里叶变换、微积分等数值变换操作,得到理想数据。This paper is about the design and implement of the data acquisition system which includes four channels and convenient to use. Associated with the firmware and application software the system can sample the analog signal and then transform it into digital signal, at last these data saved to the PC, through data transform such as filter, FT, differential and integral calculus we get the final data result.
