Abstract
Diplomsko delo obravnava tematiko nadzora električnih porabnikov na daljavo. V začetku so zajete nekatere obstoječe rešitve, čemur sledi opis problema. Glavni del naloge zajema predstavitev razvoja mikrokrmilniškega sistema za daljinski nadzor električnih naprav, s podrobnejšim opisom posameznih sklopov vezja. Na koncu je razložena uporabljena programska koda. Rešitev predstavlja izdelan krmilni modul, ki se nahaja na oddaljeni lokaciji in je povezan z lokalnim GSM modemom. Ta skrbi za komunikacijo z uporabnikom, ki nadzira modul prek telefona. Poleg vklapljanja in izklapljanja naprav lahko uporabnik poizveduje tudi po njihovem stanju in veličinah, ki jih zaznavajo senzorji. Te informacije modul posreduje uporabniku v obliki SMS sporočila. Osrednji del izdelanega modula predstavlja mikrokrmilnik PIC18F4520, ki z uporabo asinhronske serijske komunikacije komunicira z GSM modemom. Mikrokrmilnik je povezan tudi z DTMF dekoderjem, ki omogoča upravljanje modula s stacionarnim telefonom.

Title:Microcontroller system for remote control of electrical devices
Abstract:
The thesis covers the issue of remote control of electrical devices. At the beginning some of the existing solutions are described. A description of the problem follows. The main part is the development of microcontroller system for remote control of electrical devices, including a description of the individual parts of the circuit. Finally, the programming code used is explained. The solution is a produced control module, located remotely and connected to a local GSM modem. The modem is used for communication with the user that controls the module over the telephone. In addition to turning devices on and off the user can also inquire their status and quantities detected by the sensors. The module provides this information to the user via SMS. The central part of the module is a PIC18F4520 microcontroller, which communicates with a GSM modem via serial communication. The microcontroller is also connected to the DTMF decoder, which allows controlling the module via land line.

Keywords:remote control, automation, SMS, DTMF signaling, PIC18F4520, MT8870DE, sensors, asynchronous serial communication
