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.

Summary


From a 1-wire® serial communication to a GPIB connection cable with at least 24 wires, to a USB to Serial connector, and so on, the choice of using one particular connecting wire or cable over another one or, on the other hand, the availability of certain bus on a computer or a standalone test system may vary depending on at what stage of development (R&D, development, or production) we may be. The choice of connection cable/adapter device will also will have a decisive effect on the data transfer rate. The data transfer rate could be the single deciding factor with which a connection bus may have to be used. Clearly, a GPIB data transfer rate is much higher than a simple serial data transfer rate. The format of the data acquired (numbers, text, wave form, and so on) is also fundamental to data acquisition. We will look at I2C, 1-wire or 3 wire Serial, RS232, GPIB and USB, and, in particular, virtual serial port(s) using a USB connection in upcoming chapters.
