数据采集编程指南 上篇

说明：  Labview，数据采集例程，带子VI，(Labview, data acquisition routines, have SubVI)

labview TDMS的各种高速存储功能，(LabVIEW TDMS a variety of high-speed storage function,)

详尽的介绍了LabVIEW中数据库工具包在数据库连接设计中的应用(Detailed description of the LabVIEW Database Toolkit Database Connection Design)

说明：  采用cvi语言编写 对agilent 34970a万用表进行初始化设置，可作为在 labwindows/cvi使用agilent 34970a万用表进行数据采集的参考代码(Cvi language used to initialize agilent 34970a multimeter settings, can be used as in labwindows/cvi using agilent 34970a multimeter for data collection reference code)

编写软件为labview2011，功能为读取txt文件中的值，并绘制电平图，设置了双游标，可以自动准确计算出两游标X轴时间差值。txt的内容为上升沿或下降沿的时间信息，首位0代表下降沿，1代表上升沿。后面位的值乘16代表沿的绝对时间(program software is the labview2011, functions is to read txt file values​ ​ , and draw level diagram, set up a dual cursors, you can automatically and accurately calculate the time difference between the two cursors X axis. txt contents of rising or falling time information, the first 0 represents falling, a representative of the rising edge. Followed by 16-bit value represents absolute time along)

虚拟仪器是现代测量技术和计算机技术相结合的产物，标志着自动测试与电子测试仪器领域技术发展的一个崭新方向． 随着信息技术和计算机技术的高速发展，数字信号处理作为一门新兴的学科，其重要性日益在各个领域的应用中体现出来。本文介绍了利用LabVIEW 图形编程语言进行虚拟仪器开发的方法，设计了一种基于PC机声卡的虚拟示波器，说明了虚拟仪器在现代测试领域中的重要地位以及其广阔的发展前景． 从某种意义上说，“软件就是仪器”。(Virtual instrument is the produce that merges the computer technology and measurement technique．It stands for a brand new development directory in the field of auto-measurement and electronic measurement。 With the rapid development of information technology and the computer technology, the digital signal processing takes an emerging discipline, its importance displays day by day in each domain application. This article introduces how to develop virtual instruments using graph programming language-LabVIEW ,designs a virtual signal displayer based on PC and explains the important part and wide development prospects of virtual instrument in modern measurement technique field． In a sense, “The software is an instrument”.)

一个很好的入门材料，介绍了如何使用labview实现TCP/IP网络通讯，可以配合官方manul学习(A good introductory material describes how to use LabVIEW to achieve TCP/IP network communication, can cooperate with official manual learning)

基于labview的简单变声程序，简单而有趣，可以尝试一下，并做出改进(Labview program based on a simple change of sound, simple and fun, you can try and make improvements)

基于Labview环境编程的随机数求和界面显示，内容包含前台和后台等的建立(Based on the Labview environment programming of random number and interface display, the content includes the front and back and so on)

实现了Labview中格式为TDMS的数据文件的读取，并能够在波形图表中显示数据文件中记录的波形。(Achieved in Labview TDMS data file format is read, and the ability to display data in the waveform chart waveform records in the file.)
