程序结构 《LabVIEW 程序设计从入门到精通》随书教学课件及习题（基础篇部分）(Program structure LabVIEW program from the entry to the master " with the book courseware and exercises (Basics section))

说明：  基于TCP/IP协议的声音传输，包括上位机和下位机(Voice transmission based on TCP / IP protocol)

用于对于轴承振动信号的共振解调程序，便于对轴承故障信号进行分析(Used for resonant demodulation of bearing vibration signals for easy analysis of bearing fault signals)

说明：  主要用于labview excel读取（源代码）(Mainly used for reading LabVIEW excel (source code))

在波形Graph显件上用两种不同颜色显示一条正弦曲线和一条余弦曲线，每 条曲线长度为128个点，其中正弦曲线的x0 =0，△x=1；余弦曲线的x0 =2， △x=5。并利用属性节点通过前面板控件改变每条曲线的颜色。 ①一个周期128点。 ②改变颜色一定要先选择曲线，然后再改变颜色。(A sine curve and a cosine curve are displayed in two different colors on the waveform Graph display. The length of the bar curve is 128 points, where the sine curve x0 =0, Delta x=1, the cosine curve x0 =2, Delta x=5. And use the attribute node to change the color of each curve through the front panel control. One cycle is 128 points. Change the color must first choose the curve, then change the color.)

说明：  摘要：以实际工程为背景，介绍了在I丑bwindows／CVI环境下，基于ActiveX技术访问Microsoft Excel 2003的方法，以及创建 自动化仪器驱动器的方法。详细阐述了访问Excel具体函数的使用方法，实现了对Excel的访问。通过该工程实例，说明 了本方法具有重要的工程实用价值。(Abstract：The approach of accessing to Microsoft Excel 2003 based on ActiveX technology in LabWindows／CVI environment is intrt~ uced，in 8cN~ence，the establishments of driving scheme for automatic instruments are presented in detail．To realize the access to Excel，the operations of accessing to the real functions are intensively illustrated as wel1．Th e experiments in the real environment demonstrate that this method illustrated here is of great value for practical applications．)

实用LabVIEW软件 实现短时傅里叶变换。实现对数据的时频分析(LabVIEW software utility short time Fourier transform. Achieve time-frequency analysis of data)

通过串口把读到的温度 用波形显示 针对于仪器仪表温度测量(Through the serial port to read the temperature with a waveform display for temperature measurement in instrumentation)

说明：  基于.Net的DirectShow LIB包，可以用于Labview调用DirectShow，实现对相机的控制(The. Net-based DirectShow LIB package can be used to call DirectShow by Labview to control the camera.)

实现Kvaser的CAN通讯，能实现简单的读写CAN信号。(The CAN communication of Kvaser can be realized, and CAN signal can be read and written simply.)
