Automatized and virtual measurement systems

Subject description

a) structure of automatized and virtual measurement systems (system components, limitations, design steps, integration of the measurement system)

b) quantization and analogue to digital conversion (theory, practical implementation, presentation of different A/D conversions with their influences to the measurement signal)

c) communication interfaces (computer, industrial, speed, distance, fault tolerance, number of instruments on the bus)

d) software and development tools for automation of measurements (classical tools, graphical programming, data and event driven software)

e) hardware (requirements, integration, noise generation and troubleshooting)

f) software quality (software testing, black and white box, testing limitation, practical examples)

The subject is taught in programs

Objectives and competences

The objective of the course Automatized and virtual measurement systems is to understand all important parts of measurement systems and appropriate software. In scope of the course, the student is introduced to serial and parallel interfaces (laboratory and industrial measurement processes).  The course contains information regarding digital signal processing in metrology as well as development tools for automation of measurements in industrial and research. In parallel, modern virtual programming languages and their implementation are discussed. Student identify key parameters of quality assurance of software measurement equipment

Teaching and learning methods

In scope of the lectures the theoretical background on particular subjects related to automatized and virtual measurement systems together with presentation of simple practical examples is given. A complete study material is available to the students.

Practical work is being performed in the laboratory environment and seminar, and is accomplished in steps acquainting students with the problem and automatized and virtual measurement system. The problem is identified, defined and solved in appropriate steps. Project group is consisted of maximum two students, who accomplish the automatized and virtual measurement systems in different environments and areas. At the end of semester, students report on their results of laboratory exercises and seminar. 

Expected study results

After successful completion of the course, students should be able to:

  • Define, design and implement automatized and virtual measurement systems in different areas
  • Specify how virtual measuring systems are made using modern virtual programming languages
  • Use and implement developed solutions in real environment and different areas
  • Recognise basic elements of software quality
