Abstract

U ovom diplomskom radu se ostvaruje dvosmjerna komunikacija temeljena na MQTT protokolu kojom se povezuju događaji iz stvarnog i virtualnog okruženja. Pomoću alata koje posjeduje program Unreal Engine 5, postavlja se virtualna inačica Laboratorija za projektiranje izradbenih i montažnih sustava te se modeliraju uređaji unutar prostora koji posjeduju senzore za praćenje promjena unutar istog, prvenstveno osvjetljenje i hladnjak. Nadalje, koristeći MQTT plugin i Blueprint sustav programiranja unutar Unreal Engine-a 5, definira se logika odvijanja animacija uređaja u virtualnom okruženju i razmjene MQTT poruka između uređaja i njihovih virtualnih inačica. Tako se dobiva potpuno funkcionalan model digitalnog blizanca laboratorija koji omogućava praćenje i kontrolu stanja unutar stvarnog okruženja. Također, integrira se i postojeće rješenje interneta stvari s Home Assistant platformom u kojoj je definirana komunikacija uređaja u stvarnom okruženju radi daljinskog upravljanja uređajima.

Abstract (english)

In this masters thesis, two-way communication based on the MQTT protocol is implemented to connect events from both the real and virtual environments. Using tools provided by the Unreal Engine 5 program, a virtual version of the Laboratory for Manufacturing and Assembly Systems Planning is set up and devices within the space equipped with sensors for monitoring changes, primarily lighting and a refrigerator, are modeled. Furthermore, using the MQTT plugin and the Blueprint programming system within Unreal Engine 5, the logic for device animation in the virtual environment and the exchange of MQTT messages between the devices and their virtual counterparts is defined. This results in a fully functional digital twin model of the laboratory, allowing monitoring and control of the real environment's state. Additionally, the existing Internet of Things solution is integrated with the Home Assistant platform, where the communication of devices in the real environment for remote control is defined.
