A Platform for Simplified Use of the Internet of Things

Glavna pretpostavka ovog rada jest nedostatak platformi koje omogućuju nestručnim korisnicima da povezuju svoje pametne stvari i njima upravljaju, odnosno kreiraju svoje vlastite jednostavne sustave povezanih stvari, bazirane na principu Interneta stvari. Na temelju te pretpostavke funkcionalno i arhitekturno je osmišljen sustav koji nudi jednostavno korisničko sučelje putem kojeg bi korisnici mogli na jednostavan način povezivati pametne stvari i kreirati pravila po kojima bi se one trebale ponašati. Sustav je ostvaren na principu klijentsko-poslužiteljske arhitekture web aplikacije, uz pohranu podataka u relacijsku bazu podataka. Uz to, ostvaren je i dio sustava koji je odgovoran za komunikaciju i upravljanje pametnim stvarima putem protokola MQTT. S obzirom na nedostatak stvarnih pametnih stvari, ostvarene su simulacije triju pametnih stvari; sobnog termometra, garažnih vrata te klima uređaja. Kreiranjem pravila ponašanja tih triju pametnih stvari u međusobnoj ovisnosti putem korisničkog sučelja te samom simulacijom tih stvari u stvarnom vremenu demonstriran je način rada i ponašanja cjelokupnog ostvarenog sustava. Ostvarenjem platforme s odabranim funkcionalnostima te na temelju osmišljene arhitekture, ostvaren je cilj ovog rada.The main premise of this thesis is a lack of platforms that would enable nonproficient users to connect and manage their smart devices and to create their own simple connected environments according to the principles of Internet of things. Based on this premise, a system has been designed, functionally and architecturally, that enables a simple user interface for users to connect smart devices and create rules for their behavior. The designed system has been implemented through a client-server web application architecture, with data storage in a relational database. The implementation also includes the part of the system responsible for communication and management of smart devices based on the MQTT protocol. Due to current insufficient availability of actual smart devices on the market, three smart devices have been simulated: a room thermometer, a garage door and an air conditioner. The operation and behavior of the implemented system has been demonstrated by creating rules for behavior of the simulated smart devices and their interaction through the user interface, as well as by the actual real-time simulation. With the implementation of a platform for simplified use of the Internet of Things with selected functionalities and based on the designed architecture, the goal of this thesis has been achieved
