Teaching the practical aspects of engineering to potential engineers is a very important part of their education and it may also play a key role in their understanding of the engineering courses taught at universities. This paper describes how a virtual instrumentation based laboratory can be used to teach undergraduate students in "Metrology and Quality Engineering" at the Electrical and Electronic Engineering Department of the Technical University of Lodz. The low cost involved in building the laboratory was achieved by setting it up as a multifunctional flexible laboratory with shared...
An international educational project "Sensor" has been approved by the European Commission in the framework of Leonardo da Vinci programme. During the next three years, international partners from 8 countries will create educational materials of several expertise levels from university to apprenticeships and requalification of unemployed. An integral part of this project is the WWW-information system and sensor information database supposed to serve for distance-learning purposes.
The paper presents the experience of the team of the Technical University of Gdansk (TUG), Chair of the Electrical Measurements in using Virtual Instruments for educational purposes. These instruments can be used with great success for demonstration different physical phenomena during the lectures, especially to present different rapid effects in slow down time scale. They form marvellous help in understanding many theoretical problems. The virtual instruments can also be used in the virtual home laboratory, which enables students better preparation for real laboratory tasks. It is also...
The paper deals with finite element modeling of the rotational motion sensor that uses Coriolis effect and vibrating quartz tuning fork to sense angular velocity. The computation model is applicable to both studying the performance of measurement system in various modes of operation and evaluating the indeterminacy of measurement results due to the parameters’ deviations and external disturbances.
Students need be well trained in performing correct measurements. This paper reports on a training program in which emphasis is put on a critical attitude with respect to the whole measurement process. A meticulous analysis of the measurement environment, the measurement devices and the signal processing are prerequisites for an unambiguous interpretation of the measurement results. These skill are trained using a complete system built up in modules that can be studied separately. Error analysis is part of the training program and is performed on a real measurement.
Sometimes indirect measurement methods are preferably used though basic measurements are achieved in the direct methods. The main scheme of an indirect measurement is a decision of an appropriate transducer. The transducers and methods of them have been shown in many textbooks of measurement engineering, and most of physical quantities are changed to electric quantity by higher order transformation on intelligent measurement methods. In higher-level measurement, electric quantity must be changed to appropriate dimension though the electric quantity is directly used in the usual measurement...
Attractive implementations of DSP tools for measurement can improve students’ interests for deeper study of signals theory. The experiment set-up is based on standard equipment that the students can find at home. The application of DSP tools should show them importance of random signal analysis and hardware implementation issues.
At Delft University of Technology a half-day (4 hours) oscilloscope practical training course has been developed to support two activities in the start of the freshman year. The first is an introductory lecture on Instrumentation and Measurement and the second is a series of hands-on laboratory activities offered to students throughout the academic year. The target group, therefore, is freshman students, whose prior knowledge of electrical engineering is mainly determined by an introductory circuit course and the high school curriculum on physics.The objectives, structure and results of the...
A project-oriented course is described in which teams of students learn to apply knowledge from lectures on measurement, system simulation and transducer technology by creating in a structured way original mechatronic systems. Starting point of the project is a specific transducer that first has to be fully characterised by measurements and modelling. A next step is the design of a mechatronic system using this transducer. The design must be evaluated, simulated and finally built, validated and demonstrated. Students follow in a creative atmosphere a strict design trajectory while learning...
The digital signal processing laboratory play a very important role in teaching students within the metrology and quality engineering study program. The importance of DSP is outlined in this paper. The example of a student workbench is described in details and the structure and the features of a set-up are given. The advantages of the concept and some remarks how students feel about this workbench and programme of the experiment are pointed out. The specifications of the instruments used are given. One of the advantage of the set-up is a possibility to perform the experiment from different...
