Rolling machines are often used for forming flat elements or pipes. Problems occur when used to produce cylindrical elements other than pipes, or when experimental materials are used. It is required to introduce flexible control of the rolling process parameters in such cases. It is necessary to monitor the device operating parameters. When a rolling machine works with experimental materials, there are no typical control and acquisition data systems available. The article presents the concept and capabilities of the control and computer data acquisition system supporting the rolling process. The main task of software system is acquisition of force and kinetic parameters related to the analysed process of the compression during rolling. This system allows current recording and analysis of five physical values. The acquisition data application is developed in National Instruments LabVIEW environment. The software algorithm is based on the state machine. The article contains a detailed description of hardware and software implementation of the functions mentioned.

The current project is an extension of the original “ETME 475-Mechanical Systems Design” course project with a new National Instruments data acquisition board, a newly developed LabVIEW data acquisition program, and with a more realistic heat transfer loop. The study covers performance of our heat pump operating in A/C mode as well as in heating mode with a commercial desuperheater (a cross-flow heat exchanger). For this project, the experimental set up consisted of a desuperheater spliced into Trane XL1000, 2-ton, 10-SEER heat pump and a heat transfer loop with a 72-liter hot water storage tank. The instrumentation consisted of seven copper-constantan thermocouples and a LabVIEW-based computer data acquisition system. The thermocouples were used to measure refrigerant, water, indoor air and ambient air temperatures. The LabVIEW based computer data acquisition system was used to record temperatures. Indoor airflow rate was previously measured using Alnor LoFlo balometer. Results indicate that, depending on the water temperature in the desuperheater, heat pump Coefficient of Performance (COP) dropped 6–18% in A/C mode and 8–38% in heating mode. Again depending on the average water temperature in the desuperheater, the desuperheater efficiencies ranged from 12% to 27% for cooling and 11% to 39% for heating. Although even modifying an existing LabVIEW program was a challenge, the student who worked on it and the author has gained very valuable experience and enjoyed the work.

Application Programs

Since the ASYST data acquisition and analysis software was discontinued and the old versions of ASYST do not support new computer operating systems and new data acquisition boards, old computer data acquisition (CDAQ) system is being replaced with a new data acquisition system. The new microcomputer based data acquisition system consists of an i-3 microcomputer with 3.0 GHz CPU and Windows-7 operating system, a Data Translation (DT) DT-304, 12-bit, 400 MHz data acquisition board with STP-300 screw terminal, Data Translation Measure Foundry (DT-MF) software and DT-LV link software [2], a National Instruments (NI) PCI-6250, M-series, low level, 16-bit, 1.25 MS/s board with 4-module SCC-68 I/O Connector Block, four thermocouple-input plug-in modules and NI LabVIEW (NI-LV) software [4]. Data Translation’s DT-LV software links DT boards with NI-LV software. Most ASYST-based data acquisition and analysis application programs used in Mechanical Engineering Technology (MET) courses have been converted to NI-LV and DT-MF application programs. Purpose of this paper is to describe how our old data acquisition application programs were converted to new data acquisition application programs so that they may be used with our new data acquisition system. Descriptions of the experiments, equipment used, and experiences gained with laboratory experiments are given elsewhere [8–13]. Specifically: Reference [8] covers upgrades made to the Materials Testing Laboratory, including Tinius-Olsen [14] tensile testing machine; reference [9] covers design and development of data acquisition programs for the materials testing, including Tensile Testing of Materials experiment; references [11] and [12] cover Heating Ventilating and Air Conditioning (HVAC) experiments and use of DAQ system in these experiments; reference [13] cover all uses of DAQ system in MET at University of Maryland Eastern Shore (UMES).

In this work, a new and low-cost Arduino-Based Data Acquisition System (ABDAS) for use in an aerodynamics lab is developed. Its design is simple and reliable. The accuracy of the system has been checked by being directly compared with a commercial and high accuracy level hardware from National Instruments. Furthermore, ABDAS has been compared to the accredited calibration system in the IDR/UPM Institute, its measurements during this testing campaign being used to analyzed two different cup anemometer frequency determination procedures: counting pulses and the Fourier transform. The results indicate a more accurate transfer function of the cup anemometers when counting pulses procedure is used.
