Navidezna resničnost predstavlja enega od pristopov digitalizacije sistemov in procesov v industriji, ki postaja pomemben del procesov za doseganje bolj učinkovitega spremljanja, nadzora in optimizacije procesov v realnem času. V nalogi je podrobneje raziskan proces digitalizacije s pomočjo navidezne resničnosti. Analiziran je pristop za vzpostavitev povezave med napravo in navidezno resničnostjo, prikazana je potrebna strojna oprema in navedene so ugotovitve. Raziskava je podkrepljena z razvojem prototipnega sistema navidezne resničnosti s sodobno hidravlično napravo, ki služi kot referenca raziskavi. V navidezni resničnosti je izdelana animacija naprave in prikaz podatkov v realnem času. Preverili smo ustreznost prikaza animacije in resničnost prikazanih vrednosti merjenih veličin v navideznem okolju. Po podrobnejši analizi ustvarjenega sistema povezave ugotavljamo, da navidezna resničnost nudi prednost intuitivnega pristopa resničnega sveta, obenem pa omogoča fleksibilnost računalniškega okolja. Uporaba tehnologije navidezne resničnosti se hitro širi v raziskovalnem izobraževanju in ima ogromen potencial za uporabo pri razvojnih in proizvodnih procesih v industriji prihodnosti. Virtual reality is one of the approaches for the digitalization of industrial systems and processes which are becoming an important part of improvements to achieve more efficient monitoring, control and optimization of industrial real-time processes. The thesis explores the process of digitalization through virtual reality in more detail. An approach to establishing a connection between the device and virtual reality is analyzed and the necessary hardware and findings are presented. The research is supported by the development of a prototype virtual reality system with a modern hydraulic device that also serves as a reference for the research. In virtual reality, the device is animated in real-time and measured data is displayed. We checked the device animation's display adequacy and checked the value of the shown values in the virtual environment. After a more detailed analysis of the created communication system, we find that virtual reality offers the advantage of an intuitive real-world approach while also allowing the flexibility of the computing environment. The use of virtual reality technology is expanding rapidly in engineering research education and has enormous potential for use in development and manufacturing processes in the industry of the future.

V diplomskem delu predstavimo tehnologije in protokole, ki omogočajo realno-časovno komunikacijo med mobilnimi aplikacijami in senzorji. Z uporabo protokola MQTT na praktičnem primeru nadzora ogrevanja stanovanja predstavimo njihovo uporabnost in lastnosti. Začnemo z izdelavo senzorja temperature, ki podatke zaznava in sporoča, ter centralnega strežnika, ki jih obdela, se na njih odzove in jih posreduje do končnega odjemalca. Nadaljujemo z izdelavo mobilne aplikacije, ki v tem primeru predstavlja končnega odjemalca. Aplikacija podatke v realnem času prikazuje in uporabniku omogoča nadzor nad ogrevanjem. Mobilno aplikacijo dopolnimo z izdelavo aplikacije za pametno uro. Ta s pomočjo obvestil in lokacijskih podatkov uporabnika opozori na vklop ali izklop varčnega načina ogrevanja. V zaključku dela preverimo, ali smo z uporabo namenske tehnologije uspeli prihraniti na količini prenesenih podatkov in pohitriti njihovo prejemanje. In this diploma paper technologies and protocols that enable real-time communication between mobile applications and sensors are presented. On the basis of the heating control system, the usefulness and features of the protocol MQTT are described. We start with the production of temperature sensor and central server. The temperature sensor detects and reports data and the central server processes, responds, and forwards data to the final client. Then, the creation of mobile application follows which in this case is represented as the final client. The application shows the data in real time and it allows the user to control the heating. The mobile application is updated by the smart watch. The smart watch alerts the customer via notifications and local data to enable or disable the energy-efficient heating. In the conclusion we check whether we have saved on the amount of transferred data and if the data receivement is speeded up.

V diplomski nalogi smo razvili spletno aplikacijo Ground Handling Supervison, s katero ima kontrolor oskrbe letala večji nadzor in pregled nad logističnimi procesi zemeljske oskrbe določenega letala. Pri njenem razvoju smo uporabili tehnologije, ki so prosto dostopne na svetovnem spletu. Predstavili smo Letališče Jožeta Pučnika Ljubljana in družbo Aerodrom Ljubljana d.o.o., ki upravlja z letališčem. Spoznali smo zemeljsko oskrbo na ljubljanskem letališču in njene službe, seznanili smo se s prometnoinformacijskim sistemom in naredili posnetek logističnih procesov pri zemeljski oskrbi letala. Spletno aplikacijo Ground Handling Supervision smo razvili v več fazah razvoja informacijskega sistema. Za izdelavo in oblikovanje interaktivnih spletnih strani aplikacije smo uporabili HTML5, CSS3, JavaScript, jQuery in AJAX. Strežniški del aplikacije smo razvili z Node.js, Express Framework, Socket.IO, Passport.js in Moment.js. Podatke o letih, uporabnikih, končanih procesih oskrbe letala, končanih procesih oskrbe letala z gorivom in sporočila med uporabniki zapisujemo v podatkovno bazo MongoDB. Aplikacija izboljša komunikacijo pri procesih zemeljske oskrbe letal in prepreči podvajanje informacij, pomembne informacije vedno pridejo do končnih uporabnikov, storitve pri zemeljski oskrbi letal se naročajo neposredno pri izvajalcu storitve, časovno beleženje procesov pa je nadgradnja obstoječega načina dela. Aplikacijo smo preverili na dveh testnih primerih in podali predloge za izboljšave, kot so beleženje vseh procesov pri zemeljski oskrbi letal ter optimizacija procesov, kjer so nujno potrebne povratne informacije in podatki o stanju posameznega procesa. In this thesis we worked on developing a web application called Ground Handling Supervision that improves the controller's control and overview of aircraft ground handling and related logistics processes. To do so, we used technology that is freely available on the Web. The thesis first presents the Ljubljana Jože Pučnik Airport and the company Aerodrom Ljubljana d.o.o., which manages the airport. It provides insight into ground handling and its services at the airport, discusses the traffic information system and replicates the logistics processes in aircraft ground handling. The Ground Handling Supervision web application was developed in the course of several phases of the information system development. Languages HTML5, CSS3, JavaScript, jQuery and AJAX were used to build and design interactive web pages and the application. As for the server part of the application, it was developed using Node.js, Express Framework, Socket.IO, Passport.js and Moment.js. All the information about flights, users, completed aircraft handling processes, completed aircraft refuelling processes and message exchanges between users is recorded in the MongoDB database. The application improves communication in aircraft ground handling and prevents data replication. Important information always reaches end users, while aircraft ground handling services are ordered directly with the service provider and process time logging upgrades the existing system. The application was assessed by means of two tests to provide suggestions for improvements, such as logging all the processes in aircraft ground handling and process optimisation where feedback and data on individual processes is of vital importance.

V diplomski nalogi je predstavljen razvoj predvajalnika vsebin digitalnega sporočanja, temelječega na brskalniku, ki je realno-časovno povezan z osrednjim strežnikom. V začetku govorimo o naravi vsebin in različni terminologiji. Predstavimo koncept podajanja vsebin Adin DS, ki nam bo služil kot vodilo za razvoj predvajalnika. Nadaljujemo z definicijo komponent, komunikacije in spletnega brskalnika kot osrednje medijske predvajalne aplikacije z njenimi znanimi prednostmi in slabosti. V zadnjem delu podamo uporabo komponent in tehnike pri razvoju predvajalne naprave Adin Device. V zaključku podamo ugotovitve in možne izboljšave na področju datotečne zaščite sistema, prenosu vsebine ter načina predvajanja video vsebine, ki bo sledil zadanim izhodiščem. Presented in the thesis is the development of digital signage player, based on web browser which is real-time connected to the central server. At the beginning we talk about nature and terminology of the content. We introduce the Adin DS concept of serving content. This concept will guide us to develop a digital signage player. We continue with description of components, communication and web browser as a central media player application with all known faults and benefits. We further describe usage of components and techniques to develop a media signage player called AdinDevice. At very end, we draw conclusions and possible improvements in fields like file-system security, content distribution and a way to play video content as desired.
