Abstract
Zaradi uporabnikovega neustreznega upravljanja z okenskimi senčili se ne izkorišča potencialni prihranek energije ter se sočasno ustvarja neugoden vpliv na udobje stanovalcev. Zaradi omenjenega je bil namen diplomskega dela izdelava avtomatskega senčnega sistema, ki optimizira dnevne vremenske razmere za zagotavljanje učinkovite izrabe energije in prijetnega bivalnega ambienta. Zaradi specifičnih situacij je bil dodaten namen omogočiti ročno upravljanje in prednastavljivo upravljanje s časovno uro. Sočasno je bil namen omogočiti centraliziran in oddaljen dostop za upravljanje, nadzorovanje in konfiguriranje celotne aplikacije. Diplomska naloga opisuje razvoj samostojnega sistema za avtomatsko senčenje, ki kot senčni element uporablja zunanje motorizirane žaluzije. Sistem se prilagaja dnevnim vremenskim razmeram za učinkovito izrabe energije in preprečevanje neprijetnega bleščanja ob nizkem položaju sonca. Predstavljeni so sklopi, ki zajemajo metodo avtomatskega pomikanja žaluzij, izgradnjo modela žaluzij in določanje optimalnega položaja žaluzij, glede na podatke senzorjev temperatur, senzorja svetlobe, položaja sonca in orientacij oken. Drugi sklop dela predstavlja izdelavo spletnega uporabniškega vmesnika, ki omogoča oddaljen dostop za upravljanje, nadzor in konfiguracijo avtomatskega senčnega sistema. Prikazana je komunikacija med krmilnikom in spletnim brskalnikom, ki z uporabo tehnologije WebSocket deluje v realnem času. Celoten sistem avtomatskega senčenja in strežnik, ki realizira oddaljen dostop bazira na mikrokrmilniku Arduino. Zaradi funkcionalnih zahtev aplikacije, je bilo potrebno izvesti ustrezno hranjenje časa in uporabniških podatkov. Delovanje sistema bo potrebno še dodatno preveriti na realnih aplikacijah in po potrebi prilagoditi nekatere parametre, ki so bili nastavljeni na podlagi simulacij.

Title:Intelligent system for automation and remote control of an external venetian blinds
Abstract:
There is a loss of potential energy savings and negative impact on occupants comfort due to the user’s improper operation of windows shades. Therefore the purpose of the thesis was to develop an automatic shading system that optimizes daily weather conditions to meet the needs of energy efficiency and comfortable ambient conditions. Due to some specific situations the aim was also to support manual control and programmable time switch control. Additionally the purpose was to enable centralized remote access to control, monitor and configure the entire system. The thesis describes the development of an automatic shading system that uses motorized external venetian blinds as a shading device. The system is adjusting itself based on daily weather conditions to achieve the desired energy efficiency and to prevent uncomfortable glare when the sun is low. Presented work describes a method for automated movement of blinds, procedure of building a blind model and logics for determining the optimal shade angle that is based on data from temperature sensors, light sensor, calculated sun position, and windows orientation. In the second part of the thesis the development of user interface is presented, which enables remote access for controlling, monitoring and configuring the automatic shading system. Presented communication between the controller and web browser is running in real-time with the use of WebSocket technology. The automatic shading system and the server enabling the remote access is entirely implemented on the Arduino microcontroller. Because of functional requirements the proper storing of time and user data had to be implemented. The system operation should be further verified on real applications and some parameters, which were set based on simulations, should be adapted if necessary.

Keywords:Automatic shading, external venetian blinds, energy efficiency, sun tracking, Arduino, WebSocket
