Abstract

U ovom radu prikazan je postupak izrade digitalnog blizanca u sklopu 3DExperience platforme na primjeru pametnog uređaja opremljenog senzorima. Prije same izvedbe uređaja u uvodu je dan pregled pojmova vezanih uz Industriju 4.0, njene glavne karakteristike i tehnologije te je objašnjeno značenje digitalno-fizičkih sustava. U nastavku je koncept digitalnog blizanca definiran kao digitalni zapis ponašanja elementa i dinamike sustava koji nastaje tokom rada sustava te pomaže pri optimizaciji njegovih radnih performansi. Da bi se ponašanje proizvoda moglo reflektirati na njihovu virtualnu inačicu u realnom vremenu, oni moraju biti opremljeni odgovarajućim senzorima, a digitalna okolina mora omogućavati prikupljanje i pretvaranje ulaznih podataka u oblik pogodan za daljnju upotrebu. U radu su navedeni koraci za realizaciju digitalnih blizanaca koji su detaljno razrađeni kroz primjer pokretne solarne platforme koja se prilagođava okolini na način da se nastoji maksimizirati učinkovitost prikupljanja energije. Pojednostavljena verzija uređaja je izrađena tako da su ostvarene glavne funkcionalnosti digitalno-fizičkih sustava te koristi Arduino mikrokontroler za upravljanje, prikupljanje i prijenos podataka o radu uređaja i stanju okoline. Arduino povezuje fizičku i digitalnu okolinu unutar 3DExperience platforme preko odgovarajuće logičke jedinice koja pretvara ulazne signale u oblik koji omogućuje pokretanje 3D modela. Time je kreirana virtualna kopija fizičkog proizvoda. Za daljnji razvoj ovog proizvoda potrebno je skupljati podatke o performansama solarnog panela te ih analizirati u kombinaciji sa podacima iz drugih izvora kako bi se rezultati analize mogli koristiti u prediktivne svrhe i za optimizaciju njegovih radnih performansi.

Abstract (english)

This thesis presents the process of creating a digital twin of a smart product equipped with sensors using the 3DExperience platform. Before the physical realization of a product an introduction to Industry 4.0, its main characteristics and technologies was given along with the description of cyber-physical systems. The concept of digital twin was defined as a digital representation of system's behavior and dynamics which is created during runtime, which is later on used for the optimization of the product's performance. To create a real time virtual representation of a product's behavior, it needs to be equipped with a number of sensors, and the digital environment has to have the ability to enable data collection and transformation so that they can be used for further analyses. Steps for the creation of a digital twin are explained in details with a use case of a solar platform that can adapt to its surrounding in order to maximize its energy production rate. The simplified version of the device was designed, that has all of the main functionalities of a cyber-physical system which uses Arduino microcontroller for control and collection of the product's performance and working conditions data. Arduino connects physical and digital environment through 3DExperience platform using a matching logical unit that translates input signals into a form that enables the motion of a 3D model, which finally represents a virtual twin of a physical product. For further development of this product performance data of the solar panel need to be analyzed together with the data from other sources so that the results can be used for predictive purposes and performance optimization.
