Selles postituses ehitame raadiosagedustuvastusel põhineva osalemissüsteemi, mis suudab registreerida 12 õpilase / personali osavõtu antud ajaakna kohta ja see süsteem võib registreerida kuni 255 külastust inimese kohta.

Mis on RFID-osalemissüsteem

Me ei vaja RFID-põhise osalemissüsteemi tutvustamist, seda kasutatakse kolledžites, kontorites, raamatukogudes, et teada saada, mitu korda on inimene või mitu inimest mingil ajal sisse ja välja tulnud.

Selles projektis ehitame lihtsaima RFID-põhise osalemissüsteemi, mis ei raskenda projekti.

“vahelduvvool alalisvooluks ”

Selles projektis kasutame RTC moodulit, mida kasutatakse osavõtusüsteemi lubamiseks ja keelamiseks etteantud ajaperioodi jooksul, et saaksime hiliseid tulijaid eemal hoida.

RFID-moodul “RFID-RC522”, mis võimaldab NXP-põhistel RFID-siltidel lugeda ja kirjutada. NXP on juhtiv RFID-siltide tootja maailmas ja me saame neid hõlpsasti veebi- ja võrguühenduseta kauplustest hankida.

Kasutatakse 16 x 2 LCD-ekraani, mis näitab teavet, näiteks kellaaega, kuupäeva, kohalviibimise arvu jne.

Ja lõpuks kasutatakse Arduino plaati, mis on projekti aju . Võite valida mis tahes tahvli versiooni.

Nüüd liigume skemaatiliste diagrammide juurde:

Arduino ja LCD ekraani ühendus:

Lihtsalt ühendage juhtmestik vastavalt alltoodud skeemile ja kasutage kontrasti reguleerimiseks 10 kilo oomi potentsiomeetrit.

Arduino ja RFID mooduli ühendus:

RFID-moodul peab olema toiteallikas 3,3 V ja 5 V võib kahjustada parda komponente. RFID-RC522 moodul töötab Arduinoga suhtlemisel SPI-sideprotokollil.

Ülejäänud ringkond:

Arduino toiteallikaks on 9V seinaadapter. Kaardi tuvastamise kohta annavad märku summer ja LED. Kohaloleku vaatamiseks, mälu tühjendamiseks ning “jah” ja “ei” on ette nähtud 4 nuppu.

See lõpetab riistvara osa.

Laadige alla järgmised teegi failid:

Link1: github.com/PaulStoffregen/DS1307RTC

Link2: github.com/PaulStoffregen/Time

Link3: github.com/miguelbalboa/rfid.git

Nüüd peame selle jaoks määrama RTC moodulile õige aja, järgige alltoodud samme koos riistvara lõpuleviimisega.

Avage Arduino IDE.
Navigeerige jaotisse Fail> Näited> DS1307RTC> SetTime.
Laadige kood üles.

Kui kood on Arduinosse üles laaditud, avage jadamonitor . Nüüd sünkroniseeritakse RTC teie arvuti ajaga.

Nüüd peate leidma kõigi 12 RFID-kaardi / sildi UID või unikaalse identifitseerimisnumbri. UID leidmiseks laadige üles allolev kood ja avage jademonitor.

Avage seeriamonitor.
Skaneerige kaart / silt RFID-moodulilt.
Nüüd näete iga kaardi jaoks mõnda kuueteistkümnendkoha koodi.
Kirjutage see üles, sisestame need andmed järgmisse programmi.
