Abstract

U okviru ovog diplomskog rada napravljena je nadogradnja sustava FERIoT koji je razvijen s ciljem da korisniku omogući da na temelju svoje lokacije komunicira s pametnim uređajima koji se nalaze u njegovoj blizini. Diplomski rad je uz uvodni dio, strukturiran u tri glavne cjeline. U prvoj cjelini dan je teorijski pregled tehnologija za unutarnje pozicioniranje koje su se koristile pri implementaciji servisa za lociranje korisnika, a to su tehnologija Bluetooth Low Energy i Wi-Fi. Druga i glavna cjelina opisuje arhitekturu sustava FERIoT te implementaciju svih komponenti koje ga izgrađuju, a to su: servis Lokator, servis Home Assistant Manager, platforma Home Assistant uz korištenje NodeRed nadogradnje te korisnička aplikacija za operacijski sustav Android. Posebno su istaknute nadogradnje na korisničkoj aplikaciji koje uključuju razvoj servisa za pozicioniranje korisnika koji osluškuje signale BLE oznaka, signale Wi-Fi pristupnih točaka ili njihovu kombinaciju te iscrtavanje interaktivne karte i korisničke lokacije na njoj koja korisniku omogućava komunikaciju s pametnim uređajima kada se nalaze u njegovoj blizini. Posljednja cjelina opisuje provedena mjerenja s ciljem testiranja razvijenog rješenja u slučaju kada se za pozicioniranje koriste samo signali BLE oznaka te za slučaj kada se koristi kombinacija signala BLE oznaka i Wi-Fi pristupnih točaka. Implementirano rješenje testirano je na osmom katu Fakulteta na kojemu su konfigurirana dva pametna prostora.

Abstract (english)

The main topic of this MSc Thesis was the upgrading of the FERIoT system that was developed for communication with smart devices in the surroundings based on user location. In addition to the introductory part, the thesis is structured in three main parts. The first par presents a theoretical overview of indoor positioning technologies used for implementing the service for locating users indoors, namely the Bluetooth Low Energy and Wi-Fi technology. The second and main part describes the architecture of the FERIoT system and the implementation of all the components that it consists of: the Locator service, the Home Assistant Manager service, the Home Assistant platform using the NodeRed upgrade, and the Android user application. The upgrades on the user application are highlighted, which include the development of a user positioning service that uses signals of BLE tags, Wi-Fi access point signals or their combination, and the drawing of an interactive map and the user's location on it, which enables the user to communicate with smart devices in his surroundings. The last part describes the testing procedure of the implemented solution for positioning in the case when only BLE tag signals are used for positioning and when a combination of BLE tag signals and Wi-Fi access points is used. The implemented solution was tested on the eighth floor of the Faculty where two smart spaces were configured.
