计算机虚拟仪器图形编程LabVIEW实验教材

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 )

使用Labview编写PC端USB通讯程序，与C8051f320进行大规模数组USB通讯。文件中Device部分是Silab提供的FileTransfer例程，适用于C8051f320；Host部分中VC程序Silab提供的原例程，Labview程序是根据VC程序自主改写移植而成。已通过测试验证。(Interface for USB communicatons on PC, was coded by Labview, and it can transfer(USB) big array with C8051f320. The Device folder from Silab s example "FileTransfer", and the VC code in Host folder also. The VI in Host folder is code basic the VC code. The VI passed test.)

说明：  非常漂亮,有特点的木质纹络界面,官网售价3100元,已经解锁.按说明操作即可使用,非安装文件.(Very beautiful, characteristic wood texture interface, official website price 3100 yuan, has been unlocked. According to the instructions can be used, non-installation files.)

说明：  基于阶次分析理论的轴承故障诊断方法，该vi 很有实用价值，希望可以给大家带来帮助。(Bearing fault diagnosis method based on the order analysis theory, the vi Is of great practical value, the hope can bring you help.)

温度采集，多通道温度采集，实现温度采集。(temperature come on here there is a good solution to fetch temperature.)

说明：  基于labview实现的控制小鸟移动躲避障碍物的游戏(Control bird movement to avoid obstacles)

labview声音和振动工具箱注册机，声音振动工具箱专业分析声音振动信号，官网有下载(LabVIEW sound and vibration toolbox registers)

智能家居，实现智能家居各项功能的labview编程(Smart home, smart home to realize various functions labview programming)

Labview与数据库Access及SQL Server的连接 基于ActiveX(Labview database connectivity Access and SQL Server ActiveX-based)
