Virtual Instrumentation Approach for Teaching EMC Concepts

Abstract

This paper illustrates the possibility of using virtual instrumentation techniques for enhancing the conventional EMC learning environment. After a short introduction into the EMC curricula, the main considerations for adopting a LabVIEW approach to create EMC educational tools are given. Then, a number of virtual instruments (VIs) concerning various EMC concepts, utilized during the EMC courses delivered by the authors, are briefly introduced. Three of them-a hardware-based VI module for experimenting with radiated electromagnetic interferences, an interactive simulation for teaching the radiation properties of the dipole antenna and an example of calculation program for EMC, which computes electrical parameters for typical PCB transmission lines-are presented in detail as case studies.

Iliustruojama galimybė naudoti virtualios instrumentuotės metodus gerinant tradicinę EMS mokymo aplinką. Po trumpo EMS programos pristatymo pateikti pagrindiniai apmąstymai, kaip adaptuoti LabVIEW, kuriant mokomuosius įrankius. Trumpai pristatyti virtualus instrumentai (VI), naudoti EMS kursuose. Trys iš jų-aparatinis VI modulis, skirtas elektromagnetinei interferencijai tirti, interaktyvi dipolės antenos spinduliavimo charakteristikų imitacija ir SMP perdavimo linijų EMS skaičiavimo pavyzdys yra pateikti detaliau.

Automated Measurement and Monitoring of the Electromagnetic Fields from GSM Systems

“…The recorded data can be analyzed with either a dedicated LabVIEW program, similar to that described in [11], or spreadsheet software, such as MS Excel.…”

Temperature monitoring system based on multiple TMP75 digital sensors and the PC's parallel port

“…Unlike many interfacing solutions, which usually require a microcontroller and firmware, the proposed system only uses a low-cost logic inverter IC, along with a few passive components. The associated control software is implemented as a set of virtual instruments (an I 2 C Driver API) for LabVIEW, due to the fact that this graphical programming environment greatly reduces the development time and offers powerful features for data acquisition, processing and presentation [9]- [11]. Details regarding the system design will be given in the subsequent section.…”
