Data Acquisition using LabVIEW

By: Behzad Ehsani

Overview of this book

NI LabVIEW's intuitive graphical interface eliminates the steep learning curve associated with text-based languages such as C or C++. LabVIEW is a proven and powerful integrated development environment to interact with measurement and control hardware, analyze data, publish results, and distribute systems. This hands-on tutorial guide helps you harness the power of LabVIEW for data acquisition. This book begins with a quick introduction to LabVIEW, running through the fundamentals of communication and data collection. Then get to grips with the auto-code generation feature of LabVIEW using its GUI interface. You will learn how to use NI-DAQmax Data acquisition VIs, showing how LabVIEW can be used to appropriate a true physical phenomenon (such as temperature, light, and so on) and convert it to an appropriate data type that can be manipulated and analyzed with a computer. You will also learn how to create Distribution Kit for LabVIEW, acquainting yourself with various debugging techniques offered by LabVIEW to help you in situations where bugs are not letting you run your programs as intended. By the end of the book, you will have a clear idea how to build your own data acquisition system independently and much more.

Alternate Software for DAQ

Devices required


We will use the following:

  • National Instrument USB 6008:

:

USB 6008 DAQ is a low-cost multifunction DAQ. As the name implies, this DAQ connects to the PC via a USB bus. Connect the USB DAQ to the PC using a USB cable. Note the auto recognition of the device by the computer on the taskbar. If all goes well, the green LED next to the input cable will blink continuously. If the drivers are not already installed, use the CD accompanying the DAQ to install the divers. It is best to check the National Instruments website to make sure that you have the latest version of the driver.

Note: It is imperative to make certain that the USB DAQ is correctly recognized by the PC running LabVIEW. One way to verify this is to look at the Device Manager under the Control Panel of Windows. If you cannot see the device in the list of devices under Device Manager, check the connections and cables, and, most importantly, verify that you have installed the correct device drivers for the specific...
