一本介绍labwindowCVI的基础教程

歪度指标是描述信号概率密度函数的重要参数。在对非平稳信号进行时域分析时，利用歪度指标反映了振动信号的非对称性，用来判断轴承是否发生碰磨。本文件中将歪度指标独立制作了子VI，便于labview程序调用。(The skewness index is an important parameter to describe the probability density function of a signal. When the non-stationary signals are analyzed in time domain, the skewness index is used to reflect the asymmetry of the vibration signals, which is used to judge whether the bearings have been touched or not. This document will be independent of the index made a sub VI, easy for LabVIEW program calls.)

说明：  调用dll文件截取最前端窗口的图像，调用需要等待200ms(Calling DLL file to intercept the front-end image)

USB设备数据读取，将USB中数据保存到电脑上(USB device data read, save the data from USB to the computer)

安立光谱仪MS9710C的Labview例程，可在labview2011，labview 8.5打开，其他版本未测试。(labview examples for Anritsu MS9710C)

说明：  振动测试分析系统软件包，适用于8.5及以上版本。(failed to translate)

说明：  图像采集，可以利用电脑摄像头采集图像并保存到指定目录下(Image acquisition, which can be collected by computer camera and saved to a specified directory)

将数据从labview保存到电子表格中，来自NI的介绍(Labview to save data from a spreadsheet, a presentation from NI)

利用操作者框架编写的程序，非常利于新手了解操作者框架(Programs written using the operator framework are very useful for novices to understand the operator framework)

峭度指标是非平稳信号故障诊断的重要参数。峭度指标对信号中的冲击成分十分敏感，冲击成分能量越大，其峭度值就会越大，在故障诊断的时域分析中十分重要。本文件中将其独立做成了一个子vi，便于程序直接调用。(Kurtosis index is an important parameter of non-stationary signal fault diagnosis. The kurtosis index is very sensitive to the impact component in the signal. The greater the energy of the shock component, the greater the kurtosis of the signal, and it is very important in the time domain analysis of the fault diagnosis. This document will be independent of a sub VI, to facilitate direct calls to the program.)

通过串口读取数据，利用示波器实现波形的显示，同时具有保存数据，回放图形的功能。(Read data through the serial port, use an oscilloscope to achieve waveform display, but also has to save the data, playback graphics.)
