Sun active tracking sistem model

Glavni cilj ovoga rada bio je realizirati sustav koji ima mogućnost aktivnog praćenja položaja sunca, kontinuiranog prikazivanja očitanih podataka i obrade istih . Da bi se uopće moglo govoriti o obradi bilo kakvih signala, potrebno je izvršiti pretvorbu iz analognog u digitalni signal. Komponenta koju za to koristimo je 10-bitni analogno digitalni pretvarač koji je integriran u ATMega32 mikrokontroleru koji je sastavio dio Arduino razvojnog okruženja. Regulacija servo motora za vršena je preko posebnih GPIO pinova Arduina koji imaju mogućnost pulsno širinska modulacije (PWM). Cjelokupan sustav je realiziran pomoću OpenPLC programskog sučelja za regulaciju i obradu podataka, ScadaBR sučelja za vizualizaciju i arhiviranje te Arduino platforme koja je služila kao periferni uređaj za interakciju sa senzorima i aktuatorima. Pomoću OpenPLC software-skog kontrolera, modbus komunikacijskim protokolom zaprimljena očitanja se prosljeđuju na ScadaBR sustav. Dakle, OpenPLC je korišten kao uređaj koji vrši aritmetičko-logičke operacije i pokreće algoritam, a ScadaBR sučelje je korišteno za vizualizaciju izmjerenih podataka. Realizirano programsko rješenje karakterizira jednostavnost, fleksibilnost, jednostavan pristup Cloudu, otvorenost koda za uvezivanje s drugim komercijalnim industrijskim platfomama i brojne druge već prethodno spomenute mogućnosti.The main objective of this document was to implement a system that has the ability to actively monitor the position of the sun, continuous display of read data and processing them. In order to be able to talk about the processing of any signals at all, it is necessary to convert from analog to digital signal. The component we use for this is a 10-bit analog-to-digital converter that is integrated into an ATMega32 microcontroller that has assembled part of the Arduino development environment. Servo motor control is performed via special Arduino GPIO pins that have the possibility of pulse width modulation (PWM). The entire system was realized using the OpenPLC software interface for regulation and data processing, ScadaBR interface for visualization and archiving of the Arduino platform, which served as a peripheral device for interaction with sensors and actuators. Using the OpenPLC software controller, the readings received via the modbus communication protocol are forwarded to the ScadaBR system. Thus, OpenPLC was used as a device that performs arithmetic-logic operations and start-up algorithms, and the ScadaBR interface was used to visualize the modified data. The implemented software solution is characterized by simplicity, flexibility, easy access to the Cloud, openness of the code to connect with other commercial industrial platforms and many other possibilities that have already been mentioned
