Course Goals
1、Understand the components of a Virtual Instrument
2、Introduce LabVIEW and common LabVIEW functions
3、Build a simple data acquisition application
4、Create a subroutine in LabVIEW
This is a list of the objectives of the course.
This course prepares you to do the following:
1、 Use LabVIEW to create applications.
2、 Understand front panels, block diagrams, and icons and connector panes.
3、 Use built-in LabVIEW functions.
4、 Create and save programs in LabVIEW so you can use them as subroutines.
This course does not describe any of the following:
1、 Programming theory
2、 Every built-in LabVIEW function or object
3、 Analog-to-digital (A/D) theory
Section I
• LabVIEW terms
• Components of a LabVIEW application
• LabVIEW programming tools
•Creating an application in LabVIEW
LabVIEW programs are called virtual instruments (VIs).
Stress that controls equal inputs, indicators equal outputs.
Each VI contains three main parts:
1. Front Panel – How the user interacts with the VI.
2. Block Diagram – The code that controls the program.
3. Icon/Connector – Means of connecting a VI to other VIs.
The Front Panel is used to interact with the user when the program is running. Users
can control the program, change inputs, and see data updated in real time. Stress
that controls are used for inputs- adjusting a slide control to set an alarm value,
turning a switch on or off, or stopping a program. Indicators are used as outputs.
Thermometers, lights, and other indicators indicate values from the program. These
may include data, program states, and other information.
Every front panel control or indicator has a corresponding terminal on the block
diagram. When a VI is run, values from controls flow through the block diagram,
where they are used in the functions on the diagram, and the results are passed into
other functions or indicators..
1、本教程是ni公司编写，质量很高。这是三小时的课程，是最基础的入门课程，另外六小时课程在这个基础上更加深入介绍，有时间我慢慢往上传。
2、不足之处是英文版资料，现在labview版本更新很快，从8.2往后就有中文版了，但中文版资料不多。其实仔细看看并不难，我尽量多发些图片对照看更容易些。
3、labview最新版本试用版软件可以从ni官方网站免费下载，不花钱的东西要充分利用，尤其对于在校学生，学习软件要多动手练习，光看书效果不好。
4、我现在先传资料，有时间慢慢解释，大家先看看，欢迎点评，对精彩点评我会放在资料的相应位置
5、分批上传，未完待续
