Abstract
V današnjem svetu so možnosti krmiljenja naprav na daljavo preko spleta skoraj neomejene. Pri vsakem uporabniku stanovanjskih prostorov z lastnim ogrevanjem se slej ko prej pojavi želja oddaljenega krmiljenja naprav in spremljanja sprememb različnih veličin. Ponudba rešitev za starejše ogrevalne sisteme je okrnjena ali pa za uporabnika cenovno neugodna. V diplomski nalogi je prikazana izdelava krmilnega sistema ogrevanja, ki si ga vsaj malo tehnično podkovan uporabnik lahko izdela sam in je zanj cenovno dostopen. Ob izdelavi sistema smo uporabljali razširjena in brezplačna programska orodja in še aktualne komponente. Glavni namen diplomske naloge je izdelava sistema krmiljenja peči na dva načina: Prvi način krmiljenja je preko klasičnega mehanskega potenciometra, nameščenega na modulu, ki ga namestimo ob peči, drugi način pa oddaljeno krmiljenje preko spleta. Na spletnem vmesniku imamo tudi možnost vklopa in izklopa naprave. Za jedro sistema je izbran mikrokrmilniški modul Raspberry Pi 2, ki je jedro celotnega sistema. Na njem teče Apache strežnik, ki poskrbi, da je z uporabo PHP in HTML upravljanje modula Raspberry Pi možno tudi iz oddaljene lokacije preko spletnega vmesnika. Preko vhodno/izhodnih GP-I/O priključkov na drugi strani, pa Raspberry Pi komunicira z vezjem, ki skrbi za vključevanje in izključevanje naprave. Vezje med drugim preklaplja med ročnim in elektronskim nastavljanjem temperature z ustreznim vklopom relejev. Tipala na vezju zajemajo podatke o veličinah, merjenih v prostoru in na sami peči (merjenje temperature, ogljikovega monoksida in prisotnost plamena).

Abstract:
Possibilities for device internet remote controlling are virtually limitless in modern world. Every user of residential property with own space heating facilities sooner or later requires remote device controlling and regulation of various settings. Older space heating designs on offer are limited in this regard or too expensive for the user. Presented thesis demonstrates the design of an affordable heating control system that at least technologically savvy user can manufacture on his own. In designing the system, we have used popular, freeware software tools and currently available components. The main purpose of presented thesis is the design of a two-mode furnace controlling system. The first mode is through a mechanical potentiometer module installed next to the furnace, the second is through Internet remote controlling. Web interface also provides for the device on-off function. Raspberry Pi 2 microcontroller module was chosen as the core of this system, run by an Apache server, enabling PHP and HTML control of Raspberry Pi remotely over the web interface. On the other hand, the Raspberry Pi uses GP-I/O pins to communicate to device on-off switching circuitry, which also facilitates switching between manual and electronic temperature settings through suitable relays. Sensors provide on-site measurements data and on the furnace itself (temperature, carbon monoxide and flame availability).
