Sa post na ito magtatayo kami ng isang RFID based na sistema ng pagdalo, na maaaring magtala ng pagdalo ng 12 mag-aaral / tauhan para sa isang naibigay na window ng oras at ang sistemang ito ay maaaring magtala ng hanggang sa 255 na pagdalo bawat tao.

Ano ang RFID Attendance System

Hindi namin kailangan ng anumang pagpapakilala tungkol sa sistema ng pagdalo batay sa RFID, ginagamit ito sa mga kolehiyo, tanggapan, aklatan upang malaman kung gaano karaming beses ang isang tao o kung gaano karaming bilang ng mga tao ang pumasok at lumabas sa anong oras.

Sa proyektong ito magtatayo kami ng isang pinakasimpleng sistema ng pagdalo batay sa RFID na hindi labis na kumplikado sa proyekto.

“paano gumagana ang isang aparato ng gps ”

Sa proyektong ito gagamitin namin ang module ng RTC, na ginagamit para sa pagpapagana at hindi pagpapagana ng sistema ng pagdalo sa loob ng isang naibigay na tagal ng panahon, upang mapanatili nating malayo ang mga huling darating.

Ang module na RFID na 'RFID-RC522' na maaaring magbasa at magsulat ng mga pagpapatakbo sa mga tag na RFID batay sa NXP. Ang NXP ay nangunguna sa paggawa ng mga tag ng RFID sa mundo at madali nating makuha ang mga ito sa mga online at offline na tindahan.

Ginamit ang isang 16 x 2 LCD display, na kung saan ay upang maipakita ang impormasyon tulad ng oras, petsa, bilang ng pagdalo, atbp.

At sa wakas ay ginagamit ang isang Arduino board na alin ang utak ng proyekto . Maaari kang pumili ng anumang bersyon ng board.

Ngayon, magpatuloy tayo sa mga diagram ng eskematiko:

Koneksyon sa display ng Arduino hanggang LCD:

Ikonekta lamang ang mga kable ayon sa diagram sa ibaba at gumamit ng 10 kilo ohm potentiometer upang ayusin ang kaibahan.

Koneksyon sa Arduino sa RFID module:

Ang module na RFID ay dapat na pinalakas ng 3.3V at 5V ay maaaring makapinsala sa mga bahagi ng board. Gumagana ang module na RFID-RC522 sa SPI komunikasyon na proteksyon habang nakikipag-usap kay Arduino.

Natitirang circuit:

Ang Arduino ay maaaring pinalakas mula sa 9V wall adapter. Mayroong isang buzzer at LED upang ipahiwatig na ang card ay nakita. Mayroong 4 na mga pindutan na ibinigay para sa pagtingin sa pagdalo, pag-clear ng memorya at 'oo' at 'hindi' na mga pindutan.

Tinatapos nito ang bahagi ng hardware.

Mangyaring i-download ang mga sumusunod na file ng library:

Link1: github.com/PaulStoffregen/DS1307RTC

Link2: github.com/PaulStoffregen/Time

Link3: github.com/miguelbalboa/rfid.git

Ngayon kailangan naming itakda ang tamang oras sa module ng RTC upang magawa ito, sundin ang mga hakbang sa ibaba na may kumpletong pag-setup ng hardware.

Buksan ang Arduino IDE.
Mag-navigate sa File> Mga Halimbawa> DS1307RTC> SetTime.
I-upload ang code.

Kapag na-upload ang code sa Arduino, buksan ang serial monitor . Ngayon ang RTC ay nasabay sa oras ng iyong computer.

Ngayon ay kailangan mong hanapin ang UID o natatanging pagkakakilanlan ng lahat ng 12 RFID card / tag. Upang makahanap ng UID, i-upload ang code sa ibaba at buksan ang serial monitor.

Buksan ang serial monitor.
I-scan ang card / tag sa module na RFID.
Ngayon makikita mo ang ilang hexadecimal code para sa bawat card.
Isulat ito, papasok kami sa data na iyon sa susunod na programa.
