基于labview的数据库操作

基于labview8.6的希尔伯特变换高精度测量低信噪比条件下两路正弦波相位差(Labview8.6 based Hilbert transform high-precision measurement of the sine wave phase difference of the two low SNR)

labview大学教程书籍例程。温度计前面板，包含输入和显示控件。(labview university course books routines. Thermometer front panel contains the input and display controls.)

说明：  使用LABVIEW制作了一个用户登录管理系统，包含了数据库模块的使用调用与介绍(Using LabVIEW to make a user login management system, including the use and introduction of database module)

这是运用LabVIEW图形化编程语言开发虚拟数字滤波器的方法，对数字滤波器原理的分析。提出了利用虚拟仪器软件平台构建数字滤波器的设计思想，并在此基础上开发出了一套数字滤波器实例(This is the use of LabVIEW graphical programming language to develop a virtual digital filter methods, the principle of the digital filter analysis. Proposed the use of virtual instrument software platform for building a digital filter design, and on this basis to develop a set of examples of digital filter)

简单的一个贪吃蛇游戏，没吃到一个苹果，蛇的长度就增加一个，通过方向键控制贪吃蛇的运动方向，使贪吃蛇不碰到墙壁和自己的身体，很好玩，大家可以多多下载来玩一下

通过labview 2017以及pcix 5922数据采集卡完成数据采集，以及文本存储，还可以从文本中读取波形幅值。(Through lab view 2017 and pcix 5922 data acquisition card to complete data acquisition, as well as text storage, you can also read the waveform amplitude from the text.)

说明：  本程序体现在NI LabVIEW 环境里实现高速数据文件存储和回放. 当连续存储大量数据时,使用TDMS格式高效地将数据保存至tdms文件中. 在本例子中,数据来源可以是软件虚拟数据(无硬件情况),也可以使用NI DAQ多功能采集板卡采集真实的数据.(This procedure is reflected in NI LabVIEW environment to achieve high-speed data file storage and playback. When the continuous storing large amounts of data, using the TDMS format for efficient data saved to tdms file. In this case, the data source can be software, virtual data (non- hardware case), you can also use the NI DAQ multifunction analog input card collecting real data.)

在LabVIEW环境下实现全景照相。在手动转动摄像头前提下，程序实现图像拼接，照片保存。(BASED on LabVIEW the program can achieve the function which panoramic camera can do,besides, it can also let you save your photos in your hardwire while your camer is connect with the computer)

本软件用于轴扭矩的测量，可以同时测量两根轴，且可自行设置应变片形式、应变片系数、弹性模量、泊松比等。(The software for the shaft torque measurement, the two axes can be measured simultaneously, and may be provided in the form of self-gage, gage coefficient, elastic modulus, Poisson' s ratio and the like.)
