20.500.12556/RUL-103332 Razvoj brezžične naprave za merjenje sile Development of wireless system for measuring force Pri prevažanju tovora je, zaradi pojava morebitnih poškodb, ključno spremljanje obremenitve. V sklopu naloge smo s pomočjo komponent nižjega cenovnega razreda izdelali napravo, s katero preko brezžične povezave merimo silo tekom transporta. Naprava deluje na principu vzmetne tehtnice, ki se uporablja za merjenje sile. Meritev sile se izvede preko meritve raztezka z uporabo zaznavala pomika pri čemer se posredno preko togosti vzmeti izračuna sila v vzmeti. Vrednost izmerjene sile se preko brezžične povezave prikazuje na osebnem računalniku. Krmiljenje in zajemanje signalov smo razvili na Arduino platformi. Brezžična povezava med Arduinom in računalnikom je vzpostavljena z Xbee brezžičnimi moduli. Napravo smo končno umerili in preizkusili na danem testnem primeru. This diploma thesis investigates the principles of measuring force during the cargo transportation. The device to monitor force was constructed using low-price components. The remote measuring location is connected with display unit using wireless connection. The force measurement is based on measuring displacement of a spring with known stiffness. The force value is displayed on the personal computer using the developed user interface written in Python programming language. The control and acquisition of the signals is based on the Arduino platform. The wireless connection between the Arduino and the computer was established with Xbee wireless modules. The device was calibrated and tested on the selected case study. vzmetna tehtnica Arduino brezžična povezava uporabniški vmesnik Python Hookov zakon spring scale Arduino Xbee module wireless communication user interface Python Hooke's law true false false [J.
