Abstract

Cilj ovog diplomskog rada je bio razviti, implementirati i detaljno ispitati sustav pametne kuće. Naglasak je stavljen na kvalitetu sustava stoga su pri izradi korištene industrijske platforme. Sustav je izgrađen u slojevitoj arhitekturi, gdje svaki sloj iznad predstavlja višu razinu apstrakcije i veću domenu djelovanja. Na najvišem sloju se nalazi Raspberry Pi 4 mikroprocesor na kojeg je instalirana klijentska aplikacija Home Assistant za uvid i kontrolu nad sustavom. Srednji sloj predstavlja Controllino Mega, industrijska inačica Arduino Mega mikrokontrolera. Controllino očitava vrijednosti senzora i mijenja stanja releja i slično. Donji sloj predstavljaju kućanski uređaji kojima Controllino upravlja: rasvjetna tijela, ventilatori, rolete i tako dalje. Komunikacija između Controllina i Raspbery Pi se obavlja MQTT protokolom, dok se temperatura i vlaga očitavaju sa senzora koristeći Modbus protokol. Precizno upravljanje grijanjem se vrši implementiranim PID kontrolerom. Za potrebe diplomskog rada izrađena je maketa u koju je instaliran ovakav sustav.

Abstract (english)

The goal of this master thesis was to develop, implement and extensively test a smart home system. Focusing on the quality of the system, industrial platforms were used. The system was built upon an architecture in layers, where top layer represents the highest apstraction and the biggest working domain. On the top layer is a Raspberry Pi 4 microprocessor with the client app called Home Assistant installed on it. The app is used for user monitoring and control. The middle layer is represented by Controllino Mega – industrial version of Arduino Mega. Controllino reads sensor values and changes relay states. On the bottom layer are home appliances which are controlled by Controllino, like light bulbs, fans, window covers, etc. Controllino and Raspberry Pi communicate with eachother using MQTT protocol, while the temperature and humidity is read from sensors using the Modbus protocol. Precise heating control is accomplished using the implemented PID controller. A small scale model has been built for testing purposes.
