Incazelo: RFID - Identification Frequency Radio - kuyisimiso sokumaka nokukhomba imishini ephathekayo, imikhiqizo yabathengi, ngisho nezilwane eziphilayo (njengezilwane ezifuywayo kanye nabantu). Ukusebenzisa idivayisi ekhethekile ebizwa ngokuthi umfundi we- RFID , i-RFID ivumela izinto ukuba zibhalwe futhi zilandelwe njengoba zihamba ukusuka ezindaweni ngezindawo.
Ukusetshenziswa kwe-RFID
Ama-tags e-RFID asetshenziselwa ukulandelela kwemishini ephezulu yezimboni nezokunakekelwa kwempilo, izinto zokwelapha, izincwadi zamabhuku, izinkomo, nezimoto. Okunye ukusetshenziswa okuphawulekayo kwe-RFID kufaka phakathi ama-wristbands for imicimbi yomphakathi kanye ne-Disney MagicBand. Qaphela ukuthi amanye amakhadi esikweletu aqala ukusebenzisa i-RFID maphakathi nawo-2000 kodwa lokhu ngokuvamile kukhishwe ku-EMV.
Indlela i-RFID isebenza ngayo
I-RFID isebenza ngezinsimbi ezincane (ngezinye izikhathi ezincane kune-fingernail) ze-hardware ebizwa ngokuthi i- RFID chips noma amathegi we-RFID . Lezi zinhlamvu zifaka i-antenna yokudlulisa nokuthola izimpawu zomsakazo. Ama-Chips (amathegi) angabanjelwa, noma ngezinye izikhathi ajowe ngaphakathi, ahlose izinto.
Noma nini lapho umfundi ehamba ngaphakathi ethumela izimpawu ezifanele entweni, i-RFID chip ehambisanayo iphendula ngokuthumela noma iyiphi idatha equkethe. Umfundi, naye, ubonisa idatha yale mpendulo ku-opharetha. Abafundi bangaphinde badlulise idatha kudatha yekhompyutha ephakathi.
Ama-RFID amasistimu asebenza kunoma yiliphi lezintambo ezine zomsakazo womsakazo:
Ukufinyelela komfundi we-RFID kuyahlukahluka kuye ngokuthi imvamisa yomsakazo isetshenziselwa yini kanye nokuvimbela ngokomzimba phakathi kwayo kanye nezinhlamvu ezifundwayo, kusuka emasentimitha ambalwa (cm) kuya kwamakhulu ezinyawo (m). Izimpawu zamagundane eziphakeme ngokuvamile zifinyelela amabanga amancane.
I-okuthiwa i- RFID chips esebenzayo ihlanganisa ibhethri ngenkathi i -RFID chips engenzi lutho. Amabhethri asiza ukukhishwa kwamathegi e-RFID ngaphezu kwamabanga amade kodwa futhi ukwandisa kakhulu izindleko zawo. Amathegi amaningi asebenza ngendlela ye-passive lapho ama-chips athola khona izimpawu zomsakazo ezingenayo kumfundi futhi ziguqule amandla okwanele ukuthumela izimpendulo emuva.
Amasistimu e-RFID asekela ukwaziswa kokubhala kuma-chips kanye nokufunda nje idatha.
Umehluko Phakathi kwe-RFID ne-Barcodes
Ama-RFID amasistimu adalwe njengenye indlela kuma-barcodes. Ngokuphathelene nama-barcode, i-RFID ivumela izinto ukuthi zikhishwe kusukela kude, isekela ukugcinwa kwedatha eyengeziwe ku-chip target, futhi ngokuvamile kuvumela ulwazi oluthe xaxa ukuthi lulandelwe into ngayinye. Isibonelo, ama-chips e-RFID ahlanganiswe nokupakisha kokudla angahle ahlele ulwazi olufana nosuku lokuphelelwa yisikhathi komkhiqizo nolwazi lokudla futhi hhayi nje intengo efana nebhakhodi ejwayelekile.
I-NFC vs. RFID
Ukuxhumana okuseduze-kwenkambu (NFC) kuyandiswa kwe-RFID band band ithuthukiswa ukusekela izinkokhelo zamaselula. I-NFC isebenzisa ibanga le-13.56 MHz.
Izinkinga ezine-RFID
Amaqembu angagunyaziwe anganqamulela izimpawu ze-RFID futhi afunde ulwazi lomaki uma ekhona futhi esebenzisa imishini efanele, ukukhathazeka ngokukhethekile nge-NFC. U-RFID uphinde wakhulisa ukukhathazeka kwangasese okunikeze ikhono lakhe lokulandelela ukuhamba kwabantu abanamathegi.
