说明：  利用matlab平台和研华板卡进行在线信号采集、小波去噪和绘制曲线的例程，可通过程序中的注释了解到如何修改数采卡和信号信息以适用于其他情况的信号采集。
(Take advantage of the the matlab platform and Advantech board the line signal acquisition, The wavelet denoising routines and draw the curve, by the comments in the program to learn how to modify the data acquisition card and signal information to apply to other cases of signal acquisition.)
