Smartplug priority assignment system

Sustav dodjele prioriteta pametne utičnice je sustav u kojemu mikroupravljač Atmel ATmega16 upravlja relejnim modulom za otvaranje ili zatvaranje izmjeničnog strujnog kruga ovisno o varijablama unešenim od strane korisnika. Mikrokontroler moţe raditi u jezgrenom načinu rada pri kojem korisnik upravlja sustavom pomoći tipki direktno spojenim na mikrokontroler i u mobilnom načinu rada gdje korisnik moţe upravljati sustavom svojim mobilnim ureĎajem koristeći Bluetooth tehnologiju. Dodjela prioriteta zamišljena je na način da korisnik koji prvi odabere ţeljeni termin i relejnu jedinicu ima prioritet nad tom jedinicom u tom terminu. Ţeli li se drugi korisnik prijaviti u tom terminu, sustav odašilje poruku na mobilni ureĎaj korisnika da je termin prethodno zauzet i ispisuje ime korisnika koji ga je zauzeo.Smartplug priority assignment system is designed as a device in which microcontroller Atmel ATmega16 controls a relay module for opening and closing alternating current circuits depending on the commands entered by multiple users. The microcontroller has 2 modes of operation. The first mode, called „Core Mode“, allows the user to enter the commands using pushbuttons near the microcontroller. The second mode of operation, called „Mobile mode“, allows the user to enter the commands by using a personal mobile device via Bluetooth technology. Priority allocation means that the first user who enters his opening period and chooses a relay number gets priority during that period for that relay. If any other user tries to connect during that period, the system will send a message to his mobile device via Bluetooth that says that that period is already occupied and it will display the name of the user that has priority during that period
