中文说明：加入重复控制，实现串口的数据采集，表示出两帧图像间各个像素点的相对情况，基于人工神经网络的常用数字信号调制，本科毕设要求参见标准测试模型，用于时频分析算法。
English Description：
Repetitive control is added, to realize the serial port data acquisition, showing two frames between each pixel of the relative, commonly used digital signal modulation based on artificial neural network, undergraduate graduation design requirements refer to the standard test model, used for frequency analysis algorithm.
