Rilesensip na ol samting i narapela kain long RFID na NFC

Intenet bilong ol samting i gat tripela bikpela teknoloji: koneksen, aidentifikesen, na data operesen. Luksave bilong ol samting em i namba wan step long bihainim Intenet bilong ol samting, em long luksave na luksave long wanwan samting i narapela kain —1{1}}

Dispela teknoloji bilong luksave long ol samting em RFID i makim bipo i bin stap klostu wankain olsem Intenet bilong ol samting, na nau evolusen teknoloji bilong RFID, NFC, i mekim bikpela wok long ol kain kain fil. Dispela atikol i toktok long aidentifikesen teknoloji bilong ol IoT divais na rilesensip namel long RFID na NFC{1}}

RFID
Kontaktless Redio Frikwensi Aidentifikesen (RFID) em i as bilong wanpela wayales komyunikesen teknoloji we i save salim ol data i go long ol data long rot bilong wayales elektromagnetik wev{{0} Tasol, wanem samting i mekim RFID i narapela kain long jeneral komyunikesen teknoloji em i as bilong en, na i no mekim ol telefon kol o salim ol teks mesej i go long ol samting, na long dispela rot ajim bilong ol samting i stap long ol samting i pas long ol samting, na long dispela rot ol i yusim ol teks mesej i go long ol samting, na ol i yusim ol mak bilong ol samting bilong luksave na bihainim ol mak bilong ol samting bilong ol samting.
RFID teknoloji i save kamap planti taim long ol samting bilong putim na ol samting bilong karim i go long ol samting bilong bihainim ol samting bilong ol samting bilong .
RFID sistem i yusim ol tag long luksave long ol samting. Antap long ol tag, ol RFID sistem tu i gat wanpela bidaireksenel wayales transiva ol i kolim wanpela Intarogeta/Rita, we i salim ol signal i go long ol tag na ritim ol fidbek bilong ol.

RFID sistem i gat wanpela rida na wanpela tag
RFID is divided into passive RFID and active RFID. Passive RFID generally refers to passive RFID without batteries, which relies entirely on receiving electromagnetic waves to drive the circuit to work, and the recognizable distance of the tag does not change. Active RFID systems generally refer to active RFID tags, whose recognizable distance will decrease as the battery level i go daun.
ETC sistem yusim RFID teknoloji i mekim rot i gutpela moa
Active RFID i save gat wanpela longpela luksave longwe, olsem ol ETC sistem bilong ol haiwe tol but na ol otomatik paking lot, we i save yusim ektiv RFID i wok long 2.4GHz{{2} Tasol, i gat wanpela bateri long ETC tag. Sapos bateri i pinis long wok.

Ol mak bilong RFID
RFID tag i gat tupela hap: wanpela integreted seket (IC) na wanpela antena:
IC i save yusim long putim na prosesim ol data, senisim na brukim ol RF signal, na tu i mas kisim eneji long ol signal em rida i autim long draivim operesen bilong em yet.
Wok bilong wanpela antena em long salim na kisim ol mak bilong wayales.
EPC kod fomat i ken senisim isi isi ol tumbuna UPC kod, em prodak barkod.

Storage blong data long ol RFID tag
The data format stored in RFID tags is generally EPC (Electronic Product Code) code. The EPC code can recognize all objects in the world. The structure of EPC codes is defined by the EPCglobal Tag Data Standard, which is a publicly available standard that can be downloaded for free from the EPCglobal Inc website.

NFC teknoloji
Klostu Fil Komyunikesen (NFC) nau em i wanpela komon komyunikesen intafes tru bilong ol mobail fon. Ol smat divais i ken senisim data long rot bilong go klostu long narapela narapela. NFC divais inap tu long toktok wantaim wanpela pasiv NFC tag long wankain rot olsem RFID.

NFC komyunikesen rot
NFC teknoloji i bin kamap long RFID teknoloji, na antap long ol komyunikesen protokol, ol NFC standet i tok klia tu long ol data eksens fomat. Kombainim ol indaksen kad rida, ol induksen kat, na poin-long-poin wok long wanpela NFC sip, em i ken luksave na senisim data wantaim ol kompatibol divais long ol sotpela distens.

Difrens bitwin NFC mo RFID

Wok frikwensi ben
NFC i ken kisim klia olsem wanpela sabset bilong RFID teknoloji, yusim 13{{1}…566MHz frikwensi ben, na RFID i gat ol narapela frikwensi ben tu.
I gat planti wok frikwensi ben bilong RFID, inkludim 125KHz long low frikwensi ben, 13.56MHz long hai frikwensi ben, 433.92MHz na 915MHz long ultra-hai frikwensi ben, na 2.45GHz long maikrowev frikwensi ben.

Komyunikesen distens
NFC i gat nem olsem klostu-fil komyunikesen, na distens bilong toktok i klostu tru, i no winim 0{2}}1m.
I gat planti kain RFID, na distens ol i luksave long en i save senis tu i narapela kain. Olsem RFID ekses kad, longwe bilong luksave i wankain olsem NFC{1}} Tasol long ol ETC aplikesen senario, em i nidim wanpela longwe luksave longwe{2}} longwe bilong luksave long longpela longwe RFID inap kamap long ol ten o iven handet mita{4}} .

Ol aplikesen senario
RFID, maski em i wok strong o i no wok gut, ol i save yusim moa yet long luksave long ol samting bilong ol samting{{0} Lojistik, trenspot, na ol samting bilong putim olgeta samting long en, olgeta i save yusim RFID teknoloji long bihainim ol samting.
Integresen bilong ol NFC sips i antap moa, olsem integresen bilong ol kad rida na ol tag. Antap long dispela, tupela daireksenel komyunikesen kapabiliti bilong NFC i bin kamap strong. Em i olsem, NFC i no inap long yusim tasol olsem wanpela tag bilong luksave, tasol tu olsem wanpela bireksenel komyunikesen rot bilong data eksens{2}}....)

NFC teknoloji i save kamap planti long ol pe bilong pe.
Ovaol, maski NFC i kamap bihainim RFID teknoloji, em i no gat senis long ol narapela narapela aplikesen senario. Moa yet, i gat planti aplikesen senario yet bilong RFID nau yet, na NFC i no inap winim ol long dispela taim i save ({1}}
Iven long ol fil blong pem mo klosem reinj objek luksave, ol QR kod oli save plei rol blong NFC long plante senario. Naoia, NFC i no wan neseseri komunikesen intafes blong ol smatfon.
