20.500.12556/DKUM-38214 AVTOMATIZIRAN DVOOSNI SLEDILNI FOTONAPETOSTNI SISTEM Z UPORABO ODPRTOKODNE PLATFORME ARDUINO IN PROGRAMSKE OPREME LABVIEW AUTOMATED TWO-AXIS PHOTOVOLTAIC TRACKING SYSTEM BY OPEN SOURCE ARDUINO PLATFORM AND LABVIEW SOFTWARE PACKAGE V diplomskem delu je predstavljena praktična realizacija avtomatiziranega dvoosnega sledilnega fotonapetostnega sistema. Krmiljenje sistema je realizirano z nizko cenovnim, odprtokodnim mikrokrmilnikom Arduino Mega 2560, v navezi s programskim paketom LabVIEW. Podrobno je opisana DLL programska knjižnica in njen uvoz, katero smo uporabili za izračun pozicije Sonca. Za določitev usmerjenosti in naklona smo uporabili dva senzorja, in sicer elektronski kompas HMC5883L in pospeškometer ADXL335. Opisan je tudi postopek branja podatkov s senzorjev preko I2C vodila in analognega vhoda. Pomik celice smo izvedli z dvema DC motorjema, katera smo krmilili s pomočjo dvojnega H-mostičnega modula in PWM-metode. This diploma paper describes a practical realization of an automated two-axis photovoltaic tracking system. Controlling the system was made possible with a low budget open source microcontroller Arduino Mega 2560 in relation with a software package LabVIEW. To calculate the position of the sun, we used a DLL program library. This program library and its import, is described in detail. To determinate the orientation and inclination, we used two sensors: an electronic compass HMC5883L and an accelerometer ADXL335. The process of data reading from the sensors through an I2C connection/protocol and an analog input is also described. We performed the movement of the cell with two DC motors, which we controlled with a double H-bridge module and PWM method. avtomatizacija dvoosni fotonapetostni sistem sledenje soncu Arduino Mega LabVIEW elektronski kompas pospeškometer automatization two axis photovoltaic system sun tracking Arduino Mega LabVIEW electronic compass accelerometer true true false [T.
