Sistem za avtomatično upravljanje ročnega vrtljivega potenciometra

GOMBAČ, NEJC (author), Križaj, Dejan (mentor)

V današnjem času je prioriteta meritve opravljati z računalnikom oz. avtomatskim merilnim sistemom, saj lahko izmerjene podatke shranimo, primerjamo z drugimi podatki in med njimi opravljamo različne primerjalne, logične ter računske operacije. To nam omogoča bistveno hitrejše reševanje problemov. Vendar pa smo včasih vseeno prisiljeni uporabljati starejšo opremo, ki ni avtomatizirana in je ne moremo upravljati z računalnikom. V nalogi sem opisal enega izmed možnih načinov avtomatizacije ročnega potenciometra. Na konkretnem primeru – merjenje histerezne krivulje – sem preizkusil, kakšna je funkcionalnost sistema, kakršnega sem si zamislil. Avtomatizacija sistema je smotrna, če je sistem hitrejši in natančnejši od ročne meritve. Poskusil sem poiskati najenostavnejšo rešitev z dokaj preprosto opremo, tako strojno kot tudi programsko. Problem sem poskusil rešiti s koračnim motorjem, pritrjenim na nosilec, ki ga postavimo ob napravo, ki jo želimo kontrolirati.

Abstract

Nowadays the priority is to take measurements with a computer or automatic measuring system so you can store the measuring data, compare them with other data or perform various comparative, logical and arithmetic operations. This allows us to speed up problem solving significantly. However, sometimes we are forced to use older equipment that is not automated and it does not allow to communicate with computer to store data. In the task I have described one of the possible ways of automation manual potentiometer. In the particular case – measuring hysteresis curve I have tested what is the functionality of the system I imagined. Automation system is efficient if the system is faster and more precise than the manual measurement. I tried to find the simplest solution with relatively simple equipment both hardware as well as software. I tried to solve the problem with a stepper motor attached to a carrier disposed adjacent to the device which we want to control.
