LVDT测试

利用labview软件编写程序对信号进行功率谱峰分析(The power spectrum peak is analyzed by LabVIEW software.)

使用labview进行信号分析，主要用到了傅立叶变换和小波分析，私家珍藏，互联网上其他地方是找不到的(Labview signal analysis, the main use of the Fourier transform and wavelet analysis,)

说明：  Labview OPC和欧姆龙PLC通讯(LabVIEW OPC and OMRON PLC communication)

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.)

本设计采用了虚拟的NI-PCI 6221数据采集卡，利用虚拟仪器及其相关技术实现了多通道数据采集。该系统具有多路采集、实时显示、存储管理与密码保护等功能。(This design uses a virtual NI-PCI 6221 data acquisition card, using virtual instruments and related technologies to achieve multi-channel data acquisition. The system has many functions, such as multi-channel acquisition, real-time display, storage management and password protection.)

说明：  labview FX-3U modbus通信(labview FX-3U communication)

利用labview的xy图，画一个圆。根据sinx^2+cosx^2 1利用labview的正弦波生成函数画出圆(Use labview s xy chart to draw a circle. According to sinx ^ 2+ cosx ^ 2 1 using labview sine wave generation function to draw a circle)

说明：  利用电脑的摄像头或者外部的USB摄像头，采集图片。(Use a computer camera or an external USB camera to collect pictures.)

说明：  zernike多项式系数的Noll序列，希望有所帮助(According to their own needs to make appropriate modification, hope to help)

本文主要论述了基于LabVIEW 的身份验证登录程序的设计与实现原理, 讨论了建立用户信息数据库以及LabVIEW与数据库的连接方式的选择,LabSQL工具的应用,实现了根据用户信息数据库进行身份验证的功能, 符合数据库信息的用户方能成功登录, 可以方便地嵌入已有的以LabVIEW 为开发工具的测控系统中。(This paper discusses the design and realization of the principle of identity validation based on LabVIEW login program, user information database as well as the choice of LabVIEW and database connections, LabSQL tool applications based on the user information database authentication user database information can be successfully logged and can be easily embedded the existing LabVIEW as the development tool measurement and control system.)
