Abstract

visoke temperature u elektronici u većini slučaja predstavljaju problem, bilo da se radi o pomicanju karakteristika aktivnih elemenata, unošenja šuma u sustav ili neželjenog gubitka električne energije isijavanjem topline.

Zbog tog razloga važne je imati sustave koji prate temperaturu u elektoničkim sklopovima.
Ovaj rad bavi se projektiranjem jednog takvog sustava namjenjem za mjerenje temperature zavojnica velikih snaga u realnom vremenu.
Sustav je izveden beskontaktnim senzorom temperature mlx90614 koji posredno preko arduino uno modula komunicira s računalom preko USB porta.
Sustav je upotpunjem sa programskom podrškom napisanom u jeziku python, koja grafičkim sučeljem prikazuje trenutnu temperaturu i temperaturu okoline u pisanom i grafičkom obliku. Programska podrška također ima opcije stvaranja zapisnika temperature u obliku .txt datoteke, grafičko prikazivanje podataka u zapisniku.

Abstract (english)

In electronics high temperatures usually present a problem, be it shifting the characterisrics of active elements, introducing noise or unwanted loss of energy due to heat dissipation.

Because of that it is important to have systems that monitor the temperature on electronic circuts.
The goal of this thesis is to design one such system for monitoring the temperatures of power inductors.
The system consists of contactless temperature sensor mlx90614 which uses an arduino uno unit to communicate with a computer via USB port.
The system comes with a software written in python that displays the data numerically and graphically. Software also has options to create log files in form of a .txt fille, and is able to plot a graph from those log files
