Šajā amatā mēs izveidosim RFID balstītu apmeklējumu sistēmu, kas var reģistrēt 12 studentu / personāla apmeklējumu noteiktā laika periodā, un šī sistēma var reģistrēt līdz 255 apmeklējumiem uz vienu cilvēku.

Kas ir RFID apmeklēšanas sistēma

Mums nav nepieciešams nekāds ievads par RFID balstītu apmeklējumu sistēmu, tā tiek izmantota koledžās, birojos, bibliotēkās, lai uzzinātu, cik reizes cilvēks vai cik cilvēku ir ieradušies un izbraukuši.

Šajā projektā mēs uzbūvēsim vienkāršāko uz RFID balstītu apmeklēšanas sistēmu, kas nepārblīvē projektu.

“atšķirība starp kombinēto un secīgo ķēdi ”

Šajā projektā mēs izmantosim RTC moduli, kas tiek izmantots, lai iespējotu un atspējotu apmeklēšanas sistēmu noteiktā laika periodā, lai mēs varētu noturēt novēlotos atnācējus.

RFID modulis “RFID-RC522”, kas var veikt lasīšanas un rakstīšanas darbības ar NXP bāzes RFID tagiem. NXP ir vadošais RFID tagu ražotājs pasaulē, un mēs tos viegli varam iegūt tiešsaistes un bezsaistes veikalos.

Tiek izmantots 16 x 2 LCD displejs, kas parāda informāciju, piemēram, laiku, datumu, apmeklējuma skaitu utt.

Un visbeidzot tiek izmantots Arduino dēlis, kas ir projekta smadzenes . Jūs varat izvēlēties jebkuru tāfeles versiju.

Tagad pārejam pie shematiskām diagrammām:

Arduino līdz LCD displeja savienojums:

Vienkārši pievienojiet elektroinstalāciju atbilstoši zemāk redzamajai shēmai un izmantojiet 10 kilogramu omu potenciometru, lai pielāgotu kontrastu.

Arduino līdz RFID moduļa savienojums:

RFID modulim jābūt darbinātam ar 3,3 V, un 5 V var sabojāt borta komponentus. RFID-RC522 modulis darbojas, izmantojot SPI sakaru protokolu, vienlaikus sazinoties ar Arduino.

Pārējā ķēde:

Arduino var darbināt no 9V sienas adaptera. Ir zummeris un gaismas diode, kas norāda, ka karte ir atrasta. Ir 4 pogas, kas paredzētas apmeklējumu skatīšanai, atmiņas notīrīšanai un pogas “jā” un “nē”.

Ar to noslēdzas aparatūras daļa.

Lūdzu, lejupielādējiet šādus bibliotēkas failus:

1. saite: github.com/PaulStoffregen/DS1307RTC

2. saite: github.com/PaulStoffregen/Time

3. saite: github.com/miguelbalboa/rfid.git

Tagad mums ir jāiestata pareizais laiks RTC modulim, lai to izdarītu, veiciet tālāk norādītās darbības ar pabeigtu aparatūras iestatīšanu.

Atveriet Arduino IDE.
Pārejiet uz File> Piemēri> DS1307RTC> SetTime.
Augšupielādējiet kodu.

Kad kods ir augšupielādēts vietnē Arduino, atveriet sērijveida monitoru . Tagad RTC ir sinhronizēts ar datora laiku.

Tagad jums jāatrod UID vai visu 12 RFID karšu / tagu unikālais identifikācijas numurs. Lai atrastu UID, augšupielādējiet zemāk esošo kodu un atveriet seriālo monitoru.

Atveriet sērijveida monitoru.
Skenējiet karti / tagu RFID modulī.
Tagad katrai kartei redzēsiet kādu heksadecimālo kodu.
Pierakstiet to, mēs ievadīsim šos datus nākamajā programmā.
