This paper presents the idea of CD-ROM aid material of basic electrical measurement laboratory elaborated for the students of the second year of studies. Till now, for realisation the task in laboratory, students obtain printed materials, which contain theoretical principles of used methods, their diagrams, and information how to realise the necessary measurements. Nowadays nearly all the students have at home fast computers with suitable memory, therefore it is possible to deliver them much more effective aid materials. Using LabVIEW of National Instruments it is possible to design virtual...
In the paper the application of the digital signal processor (DSP) evaluation module (EVM) in the students laboratory in the Institute of Radioelectronics of Warsaw University of Technology is shown. The laboratory stand built on the base of Motorola’s DSP56002EVM card is described. The software for the card, written in the processor assembler, and for the personal computer, written in LabWindows/CVI and MATLAB environments, are shortly presented. The way in which the EVM module can be used is also given.
Software can be used to help students to learn the use and properties of common electrical measurement devices. Virtual instruments are applied here to realize a self-study package. Alternating current measurements can be trained with a virtual signal generator and different types of virtual multimeters. The paper presents educational needs clarified by study diaries as well as the virtual instruments developed.
The strict theory of Fourier transformation algorithms is required in the scientific education. However, the intuition sense is also required in the measurement, because the measurement objects have many projective spaces and an appropriate measurement should be carried out on an appropriate projective space. The intuition sense will be requested in the education where not only conceptual lectures but practical examples and applications are given. One of the applications is shown on this report; that is the image processing method. These measurement methods are employed on the industrial...
In the educational process in the field of electronics and electrical engineering a breadboard method has been employing for implementing a laboratory practicum. The typical breadboard consists of kits of active and passive electrical network elements and a set of measuring instruments. Following this approach the student has to manipulate real network components which, however, are hidden inside the breadboard, and only their images on the breadboard's switching panel are within the student's reach. The demerit of the approach is that both breadboards and instruments are rather expensive...
Measurement is assumed to be the most reliable means of acquiring information on physical reality. What are the logical foundation of this conviction, and how they should be integrated in the syllabi of measurement-related courses? Abstract thinking has been considered a cornerstone of Latin civilisation. Are we facing the crisis of this paradigm in higher engineering education? These are only two among several aspects of facing reality that are analysed in this paper.
Self-calibration is one of most important methods for improving the measuring accuracy and system reliability with lower costs. The applications of the self-calibrated measuring methods is based on the design for self-calibration of instrumentation. In this paper a self-calibration orientated design of measuring instruments and systems are proposed to simplify and optimize the development and applications in the practice. System structures and design criteria are proposed to improve the error correct-ability of the measuring systems. Self-calibrated measuring systems for measurement of...
Chain Institute of Metrology (CIM) is a special college multiply supervised by the State Bureau of Quality and Technical Supervision (SBQTS) and the State Education Ministry. In this paper, The background of CIM is briefly described first Then the new strategic challenges for CIM are presented, which is not only related to the development of science and technological in the coming new century, but also to the further open police and economy reforming of China. Facing the new strategic challenges, CIM must modify its instruction ideas and its relationship with enterprises and corporations,...
Measurement has two faces. The one is “Engineering face” and the other one is “Science face”. The engineering face is well known as “Measurement Engineering” of each field. But the science face which contributes to not only all scientific fields and all engineering or technical fields but also our human life and human society does not enough known. This paper was written as a purpose to be recognized a fact that an act of measurement is the fundamental and important operation on all Learnings and all Human Activities. “Measurement Science” is a Learning to most fit in study of the fact and...
Measurement, instrumentation and test management MM is the planning and realisation of skilful mental efforts and natural (biological) and/or artificial (technological) actions to solve measurement, instrumentation and test situations. Standard situations in information acquisition and automation are that we don't know what we don't know. If we don't know, we can't control. If we can't control, we are at the mercy of chance. To get knowledge we have to get data from the pro-cesses and products. To get valid data from the processes and products, we must measure. Aim of the paper is to present...
