20.500.12556/RUL-95456 Uporaba mikrokrmilnika Arduino za merjenje vibracij z namenom monitoringa Application of Arduino microcontroller for measuring vibration during monitoring process Merjenje vibracij ter njihova obdelava in prikaz je pogost način iskanja napak ter nenormalnega delovanja naprav v industriji. V ta namen smo v zaključni nalogi predstavili osnove vibracij ter opisali način obdelave in grafičnega prikaza izmerkov vibracij. Razložili smo pomen digitalizacije in pretvorbe signala. Razvili smo cenen merilni sistem za meritev vibracij ter obdelavo in prikaz izmerkov v realnem času. Sistem je zasnovan na Arduino platformi, obdelava podatkov pa poteka na računalniku v programskem paketu MATLAB. Merilni sistem smo testirali v kontroliranih pogojih v laboratoriju ter na realnem primeru. Dobljeni rezultati so presenetljivo natančni glede na zmogljivosti postavljenega merilnega sistema. Na koncu smo izvedli raziskavo dosegljive frekvence vzorčenja ter razložili vpliv neenakomernega intervala vzorčenja. Measuring vibration is a common way of error detection or abnormal device behaviour in industry systems. For the purposes of this assignment we presented the basics of vibrations and described the method of vibration data processing and their graphic display on the computer. We presented the importance of digitalization and signal conversion. A cheap measuring system was developed for measuring, proccessing and displaying vibration data in real time. The data acquisition was performed with Arduino microcontroller. Proccessing and display of the vibration data was performed on a personal computer with MATLAB software package. The measuring system was initially tested in a controlled environment in the laboratory. After successful tests in the laboratory the measuring system was used on a working machine. The results obtained were suprisingly accurate with regard to the capabilities of the measuring system components. Finally, we identified the maximum sampling frequency and analyzed the impact of the uneven sampling interval. vibracije mikrokrmilnik arduino pospeškomer hitra Fourierova transformacija merjenje vibration microcontroller arduino accelerometer fast Fourier transform measurements true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2017-09-20 14:42:53 2017-09-20 14:42:53 2023-10-27 08:36:40 0000-00-00 00:00:00 2017 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1970-01-01 200383 1073.pdf 1073.pdf 1 BDDEFC89344B97553948E42E9EDEECB9 077fe543452ecd29df9976dda3137eca13d80dd16b3c3170c23fe2079ed13d95 c296dd1c-a1b3-11eb-a523-00155dcfd717 20.500.12556/rul/775ba795-eabe-4d69-9b94-349e9d12cfbc https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=104060 Fakulteta za strojništvo 0 0 0
