功率谱分析

说明：  基于LabVIEW的数字电压表设计。 1．掌握数字电压表的基本原理和方法； 2．基于LabView设计数字电压表并实现；(Design of digital voltmeter based on LabVIEW. 1. Master the basic principles and methods of digital voltmeter; 2. Design and implement digital voltmeter based on LabView;)

说明：  控制转台旋转角度情况下，7路光功率计同时探测光强变化，联谊和thorlabs设备，需导入子vi。(Under the condition of controlling the rotation Angle of the turntable, the 7-channel optical power meter can simultaneously detect the change of light intensity.)

说明：  简单程序labview判断任意数值完数，输入和输出(LabVIEW judge completion)

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：  通过CCD识别目标的形状，可供学习视觉编程参考(Identifying the shape of the target by CCD can be used as a reference for learning visual programming.)

使用EMD对采集数据进行数据模态分解，得到各个分量信号(Use EMD to cEMD data)

说明：  通过输入用户名和密码后登录，实现输入正确和错误提示、登录前禁用并灰显读取按钮、登录后启用读取按钮、读取并显示文本文件内容、加密程序框图查看操作。(By inputting user name and password and login, we can input correct and error prompts, disable and gray display the reading button before login, enable the reading button after login, read and display the contents of text files, and view the encrypted program block diagram.)

Labview 实现调用动态链接库 有详细说明 程序案例和与案例说明 是学习的好材料！(Labview implementation calls the dynamic link library procedures are described in detail with examples and case notes are a good learning materials!)

labviewUSB测试上位机程序，用于测试上位机与usb设备之间的通讯。(labview USB master,LabVIEW USB test host computer program, used to test the communication between host computer and USB device.)

说明：  登陆界面，能够实现对用户的注册，以及管理员能够对数据进行操作(The login interface enables users to register and administrators to manipulate data.)
