Ubale ndi kusiyana pakati pa rfid ndi nfc

Intaneti ya zinthu makamaka imakhala ndi matekinoloje atatu ofunikira: kulumikizana, kuzindikiritsa, ndi ntchito ya deta. Chizindikiro cha zinthu ndi gawo loyamba pakukhazikitsa pa intaneti ya zinthu, zomwe zikuyenera kuzindikira mwapadera ndikusiyanitsa chilichonse.

Tekinoloje yodziwitsa chinthu chowonetsedwa ndi RFID yomwe idagwiritsidwa ntchito ngati ili pafupi ndi intaneti ya zinthu, ndipo tsopano chisinthiko cha chisinthiko cha RFID, NFC, amatenga gawo lofunikira m'magawo osiyanasiyana. Nkhaniyi ikufotokoza zaukadaulo wa zizindikiritso za IT ndi ubale pakati pa rfid ndi NFC.

Woimba
Chidziwitso chosagwirizana ndi wailesi (RFID) ndi ukadaulo wopanda waya womwe umatumiza deta kudzera pamafunde opanda zingwe. Komabe, zomwe zimapangidwa ndi ukadaulo wambiri woyankhulidwa ndi cholinga chake, osayimba foni kapena kutumiza mameseji. RFID imagwiritsidwa ntchito pozindikira ndi kusanthula ma tag okhala ndi zinthu, potero pezani kasamalidwe ka chinthu.
Tekinoloje ya RFID imagwiritsidwa ntchito kwambiri pakukongoletsa komanso kuthira katundu.
Dongosolo la RFID limagwiritsa ntchito ma tag kuti azindikire zinthu. Kuphatikiza pa tags, makina opangira mapepala ali nawonso ojambula opanda zingwe otchedwa Wofunsayo / Wowerenga, omwe amatumiza zizindikiro kuti awerengere.

Dongosolo la RFID limakhala ndi owerenga komanso chizindikiro
RFID imagawidwa m'gulu la rfid komanso yogwira ntchito. Kungopeka nthambo nthawi zambiri kumatanthauza kungokhala ndi mabatire osalankhula, omwe amadalira mafunde a elekitirol kwathunthu kuti ayendetse dera kuti agwire ntchito, ndipo mtunda wovomerezeka wa tag susintha. Njira zogwirizira za RFID nthawi zambiri zimatchulira tag zogwira ntchito za RFID, yomwe mtunda wowoneka bwino udzachepa ngati gawo la batri limachepa.
Etc dongosolo pogwiritsa ntchito ukadaulo wa RFID zimapangitsa kukhala kosavuta
Wogwira RFID nthawi zambiri amakhala ndi mtunda wautali, monga etc systems ya etlo toll ndi maere oyimitsa okha, omwe nthawi zambiri amagwiritsa ntchito RFID. Komabe, pali batri mu etc tag. Ngati batire limatuluka batire, iyenera kusinthidwa kuti igwire ntchito.

Ma tag a rfid
Chipinda cha RFID chimakhala ndi magawo awiri: Chigawo chophatikizira (IC) ndi antenna:
IC imagwiritsidwa ntchito kusunga ndi kukonza deta, kuteteza ndi kuwongolera zizindikiro za RF, komanso zimafunikira kutolera mphamvu kuchokera ku zizindikiro zomwe owerenga amayendetsa ntchito yake.
Ntchito ya tinyanga ya kuphatikizira ndikulandila zingwe zopanda zingwe.
Fomu ya EPC Code ikhoza kusintha nambala ya chikhalidwe cha UPC, yomwe ndi barcode.

Kusungidwa kwa deta mu ma tag
Mtundu wa data womwe umasungidwa mu ma tag a RFID nthawi zambiri imakhala EPC (nambala yamagetsi). Code ya EPC imatha kuzindikira zinthu zonse padziko lapansi. Kapangidwe ka zikwama za EPC kumafotokozedwa ndi muyezo wa EPCGLOBE WOSAVUTA, yomwe ili mu gawo lopezeka pagulu lomwe lingatulutsidwe kwaulere kuchokera ku tsamba la EPCGLOBE EXIC.

Ukadaulo wa NFC
Pafupi ndi kulumikizana kumunda (NFC) pakadali pano pali mawonekedwe olankhulana kwambiri a mafoni am'manja. Zipangizo zanzeru zimatha kusinthanitsa deta poyandikirana wina ndi mnzake. Zipangizo za NFC zitha kulumikizananso ndi tag ya NFC chimodzimodzi monga rfid.

Njira Zoyankhulira NFC
Tekinoloji ya NFC yasintha kwaukadaulo wa NFFID Kuphatikiza owerenga makhadi akhadi, makadi okhala ndi makhadi, ndipo pozenera - ku magwiridwe a nfc chip, imatha kuzindikira ndikusinthanitsa ndi zida zogwirizana ndi mitunda yochepa.

Kusiyana pakati pa nfc ndi rfid

Gulu logwira ntchito pafupipafupi
NFC imatha kumveka ngati ukadaulo wamatekisi ya RFID, pogwiritsa ntchito gulu la 13.56mhz pafupipafupi, pomwe RFID imaphatikizanso magulu ena pafupipafupi.
There are many working frequency bands for RFID, including 125KHz in the low frequency band, 13.56MHz in the high frequency band, 433.92MHz and 915MHz in the ultra-high frequency band, and 2.45GHz in the microwave frequency band.

Kulankhulana
NFC imadziwika kuti pafupi ndi {{0}
Pali mitundu yambiri ya rfid, ndipo mtunda woyenera umasinthanso. Monga makhadi olowera a RFID, mtunda wodziwika ndi NFC. Koma kwa etc ntchito zochitika zamakono, zimafunikira mtunda wautali wodziwika bwino. Mtunda wa kuzindikira kwa mtunda wautali {3} rfid akhoza kufikira makumi kapena mamita mazana a mita.

Zolemba Zogwiritsira Ntchito
RFID, kaya ndi mphamvu kapena kungokhala, imagwiritsidwa ntchito pozindikiridwa chinthu. Zinthu, mayendedwe, ndi kukweza maluso onse amagwiritsa ntchito ukadaulo wa RFID kuti muwone katundu.
Kuphatikiza kwa tchipisi cha NFC kuli kokwera, kuphatikiza kuphatikiza kwa owerenga makhadi ndi ma tag. Kuphatikiza apo, njira yolumikizirana yolumikizira NFC yalimbikitsidwa. Ndiye kuti, NFC singagwiritsidwe ntchito ngati chikhomo chovomerezeka, komanso monga njira yolumikizirana yolumikizirana kuti musinthe deta. Pakadali pano, NFC imagwiritsidwa ntchito kwambiri m'munda wolipira.

Tekinoloji ya NFC imagwiritsidwa ntchito kwambiri pakulipiritsa
Ponseponse, ngakhale NFC imapangidwa pogwiritsa ntchito ukadaulo wa RFID, sizikhala ndi zotsatira zothandizira zochitika zosiyanasiyana. Kuphatikiza apo, pali malo ambiri omwe alipo masiku ano, ndipo NFC siyingafanane ndi nthawi yomwe ili.
Ngakhale m'minda yolipira ndi kuzindikiridwa kuvomerezedwa, QR Codes imatha kusewera gawo la NFC m'magawo ambiri. Pakadali pano, NFC siinthu zofunikira zolankhulirana za mafoni.
