Labwindows/CVI-ban fejlesztett wavelet transzformációs modul alkalmazása Labview környezetben

Abstract

This paper considers the use of National Instrument’s (NI) software development environment supporting its data acquisition cards for measurement and signal processing tasks effectively. We created a part of our program performing a relatively simple measurement task in LabVIEW environment. The more sophisticated part using complex mathematical formulas of Wavelet decomposition was created in LabWindows/CVI environment. We made it possible for the LabVIEW to use this module. We show the applicability of our measurement system through the Motor Current Signature Analysis (MCSA) of a squirrelcage induction motor with broken rotor bar.
