labview读取USB数据的升级版

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.)

用LabVIEW编制一个完整应用软件，完成以下功能： 1、产生一个正弦波，叠加一个噪声信号，从界面上可以调整噪声和信号的幅度、频率等参数，此信号作为后续分析的信号源； 2、显示信号的时域波形，点击按钮可以显示信号的幅度谱、功率谱 3、图形上可以显示光标，具有峰值跟踪功能，同时将峰值频率、幅度显示在界面上。 4、点击按钮可以计算显示信号的失真度（THD）、信噪比（SNR）、各次谐波的频率和幅度；(Preparation of a complete application using LabVIEW software, perform the following functions: 1, generates a sine wave, the superposition of a noise signal, the interface can be adjusted from the noise and the signal amplitude, frequency and other parameters, this signal as a follow-up analysis of the signal source 2. time-domain signal waveform display, click the button to display the signal amplitude spectrum, power spectrum 3, you can display a cursor on the graph, with a peak tracking, while the peak frequency, amplitude displayed on the screen. 4, click the button to display the calculated distortion (THD) signal to noise ratio (SNR), each harmonic frequency and amplitude )

自己做的PID小程序，里面有一个自己做的温度采样程序(PID do their own small program, which has an own temperature sampling procedures)

基于labVIEW的最小二乘法算拟合正弦波计算相位(Calculated based on least squares fitting labVIEW calculated phase sine wave)

监测系统 ，空转齿轮箱监测系统，包括 数据采集，报表打印，历史记录回放等等(Auto monitoring system)

Windows USB vendor class installer

非常好用的通讯转换，用于rs232，十六进制十进制转换(Very easy to use communication converter for rs232, hexadecimal decimal conversion)

提出了如何在DAQ数据采集中设置通道设置(DAQ data acquisition channel settings)

说明：  使用Labview进行实时调用摄像头、按键拍照、根据俯仰角和方向角找到图像中的位置(Use LabVIEW to call the camera in real time, press the key to take photos, and find the position in the image according to the pitch angle and direction angle)
