This paper describes computer-based systems for data acquisition and control that have been installed in an engineering laboratories at the University of Tennessee at Chattanooga. The labs include automatic feedback controls systems, chemical engineering unit operations and environmental engineering experimental stations.
All systems have data acquisition and/or control programs using LabVIEW software. The software collects the data, massages it and presents it to the student users via a graphical window analogous to a hardware panel on traditional measuring equipment. The programs are used by students for data collections on the various systems. Steady-state, step response and frequency response experiments can be and are used for system identification and design.
The systems are implemented with LabVIEW on a variety of Macintosh products ranging from Mac SE's to various Quadras and on an IBM-clone '486-DX50.
