Abstract

Osmišljeni sustav za pametno upravljanje kućom se sastoji od aplikacije Wattle instalirane na pametnom telefonu, pristupnika tvrtke HomeControl, jednog ili više Orange Pi Zero računala, lokalne mreže koja povezuje računala sa pristupnikom te dodatnog sklopovlja za upravljanje uređajima. Pristupnik i Orange Pi Zero računalom komuniciraju protokolom MQTT gdje je Orange Pi Zero klijent koji se pretplaćuje na određenu temu, a pristupnik je posrednik te u isto vrijeme i klijent koji objavljuje na neku temu. Na računalu je operacijski sustav Lubuntu te su napisani programi za komunikaciju sa pristupnikom i upravljanje uređajima pomoću ulazno-izlaznih pinova računala. U praktičnome je radu izveden sklop za reguliranje jačine osvijetljenosti koristeći detekciju prolaza sinusoide napona kroz nulu te pravovremeno paljenje i gašenje žarulje. Ostvareno je i upravljanje utičnicom pomoću releja te je dizajnirana tiskana pločica sa navedenim komponentama.

Abstract (english)

The smart home management system consists of an application Wattle, HomeControl gateway, one or more Orange Pi Zero computer, a local network that connects the computers with gateway and an additional managing hardware for devices. Gateway and the Orange Pi Zero computer communicate over the MQTT protocol where the Orange Pi Zero is a client who subscribes to a specific topic, and the gateway is a MQTT broker and at the same time a client who publishes on a topic. The computer runs Lubuntu operating system, and there are written programs for communicating with the gateway and controlling the devices by input-output pins of the computer. A circuit for light dimmer is made in practical work by using zero crossing detection and timely switching the light bulb on and off. Socket power management was achieved using a relay switch and a printed circuit board containing these components is designed.
