RFID (Radio Frequency Identification), mfundo yake ndi kulumikizana kwa data kosalumikizana pakati pa owerenga ndi tag kuti akwaniritse cholinga chozindikiritsa chandamale.Malingana ngati ndi njira yafupipafupi ya wailesi, ndipo ikhoza kudziwika motere, imawerengedwa ngati gulu la RFID.Malinga ndi ma frequency, amatha kugawidwa pafupipafupi otsika, ma frequency apamwamba, Ultra-high frequency, 2.4G ndi zina zotero.RFID imagwiritsidwa ntchito kwambiri, ndikugwiritsa ntchito nthawi zonse kuphatikiza kasamalidwe ka nyama, kasamalidwe ka magalimoto, makina opanga makina, kasamalidwe ka katundu, kasamalidwe ka ogwira ntchito, ndi chisamaliro chamankhwala mwanzeru.

Ukadaulo wa NFC (Near Field Communication) unayamba mochedwa kwambiri kuposa RFID.Inali njira yaufupi yolumikizirana opanda zingwe yomwe idalimbikitsidwa makamaka ndi Philips, Nokia ndi Sony cha m'ma 2003. Ndi njira yolumikizirana yosalumikizana ndi mtunda waufupi.Mafupipafupi ogwiritsira ntchito ndi 13.56MHz, ndipo mlingo woyankhulirana ndi 106kbit / sec mpaka 848kbit / sec.Kudzera pa foni yam'manja monga chonyamulira, kugwiritsa ntchito makhadi a IC osalumikizana ndi foni yam'manja, ndipo njira zitatu zogwiritsira ntchito makadi, owerenga ndi malo-to-point amagwiritsidwa ntchito kuti azindikire kulipira kwa m'manja, kugwiritsa ntchito makampani, kusinthanitsa mfundo, matikiti amagetsi. , kuzindikira zidziwitso, zotsutsa-zabodza, kutsatsa, ndi zina.

RFID imangotanthauza kulumikiza dera la RFID lomwe lili ndi gawo la mawayilesi a RFID ndi kuzungulira kwa mlongoti ku chinthu.Pambuyo pa chinthu chomwe chili ndi tag ya RFID chilowa mugawo linalake la maginito lokhazikika, chimatumiza chizindikiro cha pafupipafupi, ndipoWowerenga RFIDatha kupeza zomwe zidalembedwa kale pa chinthucho.Izi zili ngati baji yomwe ili pakhosi pa wogwira ntchitoyo, ndipo ndinu omuyang'anira.Akalowa pamzere wanu, mutha kudziwa dzina lake, ntchito yake ndi zina zambiri, ndipo mutha kulembanso zomwe zili mu baji yake.Ngati RFID ndikuti munthu amavala baji kuti ena amumvetse, ndiye kuti NFC ndikuti anthu awiri amavala mabaji, ndipo akhoza kusintha mosasamala zomwe zili pa baji ataonana, ndikusintha zomwe amalandira ndi gulu lina.NFC ndi RFID zimawoneka zofanana pamlingo wakuthupi, koma kwenikweni ndi magawo awiri osiyana, chifukwa RFID kwenikweni ndiukadaulo wozindikiritsa, pomwe NFC ndiukadaulo wolumikizirana.Kusiyana kwapadera kumawonekera m'mbali zotsatirazi

1. Mafupipafupi ogwiritsira ntchito: NFC pafupipafupi imayikidwa pa 13.56MHz, pamene RFID imaphatikizapo yogwira (2.4G, 5.8G), yogwira ntchito (125K, 13.56M, 915M, 2.4G, 5.8G), ndi RFID yogwira ntchito.Chofala kwambiri ndiRFID yokha, yomwe ingagawidwe m'mafupipafupi otsika (125KHz / 134.2KHz), maulendo apamwamba (13.56MHz) ndi maulendo apamwamba kwambiri (860-960) pafupipafupi.

2. Njira yogwirira ntchito: NFC imaphatikiza owerenga makhadi opanda kulumikizana, khadi lopanda kulumikizana ndi ntchito za anzawo kukhala chip chimodzi, pomwe rfid iyenera kukhala ndi owerenga ndi tag.RFID imatha kuzindikira kuwerenga ndi kuweruza kwa chidziwitso, pomwe ukadaulo wa NFC umatsindika kulumikizana kwa chidziwitso.NFC imathandizira njira yowerengera-yolemba ndi makadi;mu RFID, owerenga makhadi ndi khadi lopanda kulumikizana ndi zinthu ziwiri zodziyimira pawokha ndipo sizingasinthidwe.NFC imathandizira P2P mode, RFID sichigwirizana ndi P2P mode.

3. Mtunda wogwira ntchito: Mtunda wogwira ntchito wa NFC ndi 0 ~ 20cm, koma pakukwaniritsidwa kwa mankhwalawo, chifukwa chogwiritsa ntchito luso lapadera lopondereza mphamvu, mtunda wogwirira ntchito ndi 0 ~ 10cm yokha, kuti atsimikizire bwino chitetezo. za bizinesi;Popeza RFID ili ndi ma frequency osiyanasiyana, mtunda wake wogwirira ntchito umasiyana kuchokera ku ma centimita angapo mpaka makumi a mita.

4. Protocol yokhazikika: Njira yolumikizirana yoyambira ya NFC imagwirizana ndi mulingo wolumikizirana wa pafupipafupi wa RFID, ndiye kuti, umagwirizana ndi muyezo wa ISO14443/ISO15693.Ukadaulo wa NFC umatanthawuzanso protocol yapamwamba kwambiri, monga LLCP, NDEF ndi RTD, ndi zina zambiri, pomwe protocol ya RFID imatha kuthandizira ISO 11784&11785, ISO14443/ISO15693, ndi EPC C1 GEN2/ISO 18000-6C ndi miyezo ina molingana ndi ma frequency osiyanasiyana.Ngakhale ukadaulo wa NFC ndi RFID ndi wosiyana, ukadaulo wa NFC, makamaka umisiri wolumikizirana, umagwirizana kwathunthu ndiukadaulo wapafupipafupi wa RFID.Chifukwa chake, m'malo ogwiritsira ntchito ma RFID apamwamba kwambiri, ukadaulo wa NFC ungagwiritsidwenso ntchito.

5. Malangizo ogwiritsira ntchito: RFID imagwiritsidwa ntchito kwambiri m'mizere yopangira, kusungirako katundu, kasamalidwe ka katundu ndi ntchito zina, pamene NFC imagwira ntchito poyang'anira mwayi, makhadi a mabasi, kulipira mafoni etc.

Malingaliro a kampani Shenzhen Handheld-Wireless Technology Co., Ltd.imaphatikiza R&D, kupanga, kugulitsa ndi ntchito zogulitsa pambuyo pake.Zakhala zikuyang'ana pakupereka makondaRFID hardware ya m'manjandi ntchito zamapulogalamu zogwirira ntchito, zosungira, zogulitsa, zopanga, zamankhwala, zankhondo ndi zina kuti zilimbikitse chitukuko chonse chamakampani a IOT kwa zaka zambiri.
