||W17: Data Acquisition Using LabVIEW
||We use LabVIEW in a structured, scaffolded manner at various levels in our curriculum with a goal of producing industry-ready, research-ready graduates who are proficient with using data acquisition to solve measurement and control problems.
University Physics Laboratory students use locally-written, LabVIEW-based applications (http://physics.wku.edu/harper/apps/) that allow them to design their own experiments by selecting the sensors to use, measurements to make, and analysis to perform.
In a junior level course, Data Acquisition Using LabVIEW (PHYS 318), students learn data acquisition (DAQ) fundamentals and how to program in LabVIEW. This course is part of National Instruments' LabVIEW Academy program, which allows students the opportunity to take the Certified LabVIEW Associate Developer examination. Physics and engineering students in this course progress from writing simple applications using their own DAQ hardware to more complex applications designed to solve a problem for a local industry or WKU research group. Students who complete this course are ready to use their DAQ skills within their senior-level research.
This workshop is designed to give a snapshot of the Data Acquisition Using LabVIEW course at WKU. Participants will have the opportunity to explore two of the applications that students write in this course as exercises while they are learning DAQ and LabVIEW skills.
In the first application participants will measure and control the temperature of a small thermal plant consisting of a transistor and a thermistor in thermal contact. Temperature will be measured using the thermistor and a PID algorithm will be used to adjust the control voltage applied to the transistor in order to drive the plant to the desired setpoint temperature.
In the second application participants will measure the sound intensity from audio signals ranging from pure tones to their favorite MP3s and will calculate and display the frequency content in the signals using a power spectrum routine in LabVIEW. The sampling rate and the measurement duration will be adjustable on the fly allowing participants to investigate how these parameters effect the Nyquist frequency and the frequency resolution of the measurement.
