Inteligentno krmiljenje razsvetljave z mikrokrmilniškim sistemom

Rajh, Vid (author), Meža, Marko (mentor)

V pričujočem delu je predstavljen razvoj sistema za krmiljenje svetlobnih naprav, ki vključuje upravljanje naslovljivih LED trakov in DMX naprav z uporabo mikrokrmilnika ESP32. Sistem omogoča daljinsko upravljanje prek spletnega uporabniškega vmesnika, pri čemer komunikacija poteka preko protokola MQTT. Poudarek je bil na razvoju kompaktnega in modularnega sistema, zato je bilo v ta namen razvito tudi namensko tiskano vezje, ki združuje funkcije napajanja, komunikacije in krmiljenja. Programska in strojna zasnova sistema omogočata podporo za različne svetlobne učinke ter enostavno razširitev funkcionalnosti. V okviru naloge so bile opravljene tudi meritve odzivnega časa, ki so pokazale, da sistem deluje stabilno in z nizko zakasnitvijo. Sistem dosega vse zastavljene cilje, hkrati pa odpira možnosti za nadaljnji razvoj, kot so lokalno upravljanje, naprednejši učinki in povezava z drugimi sistemi.

Abstract

This thesis presents the development of a lighting control system designed to manage addressable LED strips and DMX devices using an ESP32 microcontroller. The system enables remote control through a web-based user interface, with communication handled via the MQTT protocol. The focus was placed on designing a compact and modular system, which included the development of a custom printed circuit board (PCB) that integrates power supply, communication, and control functions. Both the hardware and software were designed to support various lighting effects and allow for easy functional expansion. Response time measurements were also performed as part of the project, showing that the system operates reliably with low latency. The final solution meets all predefined objectives and provides a solid foundation for future improvements, such as local control, advanced effects, and integration with other systems.
