实现串口的数据采集，主要是基于mtlab的程序，包含优化类的几个简单示例程序，对信号进行频谱分析及滤波，数据模型归一化，模态振动，应用小区域方差对比，程序简单。- Achieve serial data acquisition, Mainly based on the mtlab procedures, Optimization class contains several simple sample programs, The signal spectral analysis and filtering, Normalized data model, modal vibration, Application of small area variance comparison, simple procedures.
