Kolmanko Kapitan, Tim (author), Nemec, Mitja (mentor)

Ta magistrska naloga opisuje razvoj programa, ki omogoča povezavo več merilnih instrumentov (ITech IT9121, ITech IT6000C, Newtons4th PPA5530, RIGOL DS1000Z, Agilent MSO7034A) preko LAN omrežja in njihovo daljinsko upravljanje in odčitavanje preko uporabniškega vmesnika in lastno razvitega merilnega programa. Instrumenti so bili uporabljeni za evalvacijo enosmernega napetostnega pretvornika. Analizirani so bili komunikacijski standardi, pri čemer se je VISA izkazal kot najprimernejši. Programi so bili razviti v Pythonu, s PyVISA za LAN komunikacijo. Uporabniški vmesnik omogoča nastavitev parametrov pretvornika, spremljanje temperature in upravljanje merilnih parametrov. Rezultati meritev so pokazali pričakovan izkoristek pretvornika in omogočili primerjavo med različnimi instrumenti.

Abstract

This master's thesis presents the development of a program that allows multiple measuring instruments (ITech IT9121, ITech IT6000C, Newtons4th PPA5530, RIGOL DS1000Z, Agilent MSO7034A) to be connected over a LAN network and controlled remotely using a GUI and a custom measurement program. These instruments were used to evaluate a direct voltage converter. Communication standards were analyzed, with VISA being chosen as the most suitable. The programs were developed in Python, utilizing PyVISA for LAN communication. The GUI enables setting converter parameters, monitoring temperature, and managing measurement parameters. Measurement results indicated the expected efficiency of the converter and allowed for comparison between different instruments.
