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.

Before we start on the main topic, a few words of caution are necessary. Any work we do starts with electricity, and in particular, a power supply. I do realize I have mentioned power supplies in passing in such sentences as "set power supply to such and such volts....". But it suddenly dawned on me that (maybe it is because I have several power supplies scattered around my lab) power supplies deserve much more attention than I have given them so far. Choosing the correct power supply obviously depends on the range of use it will be used for (and of the cores of your budget). But just knowing this fact is not enough. Power supplies are used in two main categories: in a rack with several instruments in which they are set once, and not so often a technician or an engineer checks them as needed, the law requires that all instruments should be calibrated by independent companies once a year. This case mostly applies to factories. The other way...
