Kako napraviti RFID sustav posjećenosti

Kako napraviti RFID sustav posjećenosti

U ovom ćemo postu izraditi RFID sustav pohađanja, koji može bilježiti prisustvo 12 učenika / djelatnika za određeni vremenski period, a ovaj sustav može zabilježiti do 255 pohađanja po osobi.



Što je RFID sustav praćenja

Ne treba nam nikakvo upoznavanje s RFID sustavom pohađanja, on se koristi na fakultetima, uredima, knjižnicama da bi se znalo koliko je puta osoba ili koliko ljudi ušlo i izašlo u koje vrijeme.

U ovom ćemo projektu izraditi najjednostavniji sustav pohađanja zasnovan na RFID-u koji ne komplicira projekt.





U ovom ćemo projektu koristiti RTC modul koji se koristi za omogućavanje i onemogućavanje sustava pohađanja nastave u određenom vremenskom razdoblju, kako bismo mogli zadržati one koji kasne.

RFID modul 'RFID-RC522' koji može obavljati operacije čitanja i pisanja na RFID oznakama temeljenim na NXP-u. NXP je vodeći svjetski proizvođač RFID oznaka i lako ih možemo dobiti u mrežnim i izvanmrežnim trgovinama.



Koristi se LCD zaslon od 16 x 2, koji prikazuje podatke poput vremena, datuma, broja pohađanja itd.

I na kraju se koristi Arduino ploča koja je mozak projekta . Možete odabrati bilo koju verziju ploče.

Sada prijeđimo na shematske dijagrame:

Priključak Arduino na LCD zaslon:

Samo spojite ožičenje prema donjem dijagramu i upotrijebite potenciometar od 10 kilograma da prilagodite kontrast.

Priključak Arduino na RFID modul:

RFID modul mora se napajati od 3,3 V, a 5 V može oštetiti ugrađene komponente. Modul RFID-RC522 radi na komunikacijskom protokolu SPI tijekom komunikacije s Arduinom.

Ostatak kruga:

Arduino se može napajati iz 9V zidnog adaptera. Postoji zvučni signal i LED dioda koji ukazuju na otkrivanje kartice. Na raspolaganju su 4 gumba za pregled prisutnosti, brisanje memorije i gumbi 'da' i 'ne'.

Time je zaključen hardverski dio.

Molimo preuzmite sljedeće datoteke iz biblioteke:

Link1: github.com/PaulStoffregen/DS1307RTC

Link2: github.com/PaulStoffregen/Time

Link3: github.com/miguelbalboa/rfid.git

Sada za to moramo postaviti točno vrijeme za RTC modul, slijedite korake u nastavku s dovršenim postavljanjem hardvera.

  • Otvorite Arduino IDE.
  • Idite na Datoteka> Primjeri> DS1307RTC> SetTime.
  • Učitajte kod.

Nakon što se kôd prenese na Arduino, otvorite serijski monitor . Sada je RTC sinkroniziran s vremenom vašeg računala.

Sada morate pronaći UID ili jedinstveni identifikacijski broj svih 12 RFID kartica / oznaka. Da biste pronašli UID, prenesite donji kod i otvorite serijski monitor.

  • Otvorite serijski monitor.
  • Skenirajte karticu / oznaku na RFID modulu.
  • Sada ćete vidjeti neke heksadecimalne kodove za svaku karticu.
  • Zapišite to, te podatke ćemo unijeti u sljedeći program.
