Amavu n'amavuko
NFC. Sisitemu y'itumanaho ya NFC ikubiyemo ibice bibiri byigenga: umusomyi wa NFC na tagi ya NFC. Umusomyi wa NFC nigice gikora cya sisitemu "isoma" (cyangwa itunganya) amakuru mbere yo gutanga igisubizo cyihariye. Itanga imbaraga kandi ikohereza amabwiriza ya NFC mugice cya passiyo ya sisitemu (ni ukuvuga tagi ya NFC). Mubisanzwe, ifatanije na microcontroller, umusomyi wa NFC atanga imbaraga kuri no guhana amakuru hamwe na label imwe cyangwa nyinshi za NFC. Umusomyi wa NFC ashyigikira protocole nyinshi za RF n'ibiranga kandi birashobora gukoreshwa muburyo butatu: soma / wandike, urungano rwawe (P2P) no kwigana amakarita. Imirongo ikora ya NFC ni 13.56 MHz, ikaba ari iyumurongo mwinshi, naho protocole ni ISO / IEC 14443A / B na ISO / IEC15693.
Ibirango bya NFC bifite porogaramu zitandukanye, nko guhuza no gukemura, ibyapa byamamaza, kurwanya impimbano, n'ibindi.
1.Kuringaniza & Gukemura
Mu kwandika amakuru nk'izina n'ijambobanga rya WiFi kuri label ya NFC ukoresheje umusomyi wa NFC, ugashyiraho ikirango ahantu heza, ihuza rishobora gushirwaho mugushira gusa ibikoresho bibiri bifasha NFC hafi yundi. Byongeye kandi, NFC irashobora gukurura izindi protocole nka Bluetooth, ZigBee. Kuringaniza mubyukuri bibaho mumasegonda abiri kandi NFC ikora gusa mugihe ubikeneye, ntihazabaho rero guhuza ibikoresho byimpanuka kandi ntihazabaho amakimbirane yibikoresho nka Bluetooth. Gukoresha ibikoresho bishya cyangwa kwagura urugo rwawe nabyo biroroshye, kandi nta mpamvu yo gushakisha ihuza cyangwa kwinjiza ijambo ryibanga.
Isesengura ryo guhitamo ibicuruzwa
Chip: Birasabwa gukoresha urukurikirane rwa NXP NTAG21x, NTAG213, NTAG215 na NTAG216. Uru ruhererekane rwa chip rwujuje ubuziranenge bwa NFC Ubwoko 2 kandi rwujuje na ISO14443A.
Antenna:NFC ikora kuri 13.56MHz, ikoresheje aluminium yogukora coil antenna AL + PET + AL.
Glue: Niba ikintu kigomba gukurikizwa cyoroshye kandi ibidukikije bikoreshwa ni byiza, igiciro gito gishyushye gishushe cyangwa kole y'amazi irashobora gukoreshwa. Niba ibidukikije bikoreshwa bikabije kandi ikintu kigomba gukurikizwa kirakomeye, kole yamavuta irashobora gukoreshwa kugirango ikomere.
Ibikoresho byo hejuru: Impapuro zisize zirashobora gukoreshwa. Niba amazi adakenewe, ibikoresho bya PET cyangwa PP birashobora gukoreshwa. Icapiro hamwe nicyitegererezo birashobora gutangwa.
2. Kwamamaza & Ibyapa
Ibyapa byubwenge nibimwe mubikorwa bya tekinoroji ya NFC. Yongeraho ibimenyetso bya NFC kumatangazo yumwimerere cyangwa ibyapa byamamaza, kugirango mugihe abantu babonye iyamamaza, barashobora gukoresha terefone zabo bwite kugirango basuzume tagi yashyizwemo kugirango babone amakuru yamamaza yamamaza. Mubyerekeranye na posita, tekinoroji ya NFC irashobora kongera imikoranire. Kurugero, icyapa kirimo chip ya NFC kirashobora guhuzwa nibirimo nkumuziki, videwo, ndetse nudukino twa interineti, bityo bikurura abantu benshi kuguma imbere yicyapa kandi bikongera ibitekerezo byamamaza hamwe ningaruka zo kuzamurwa. Hamwe no gukundwa na terefone zigendanwa zifite imikorere ya NFC, ibyapa byubwenge bya NFC nabyo bikoreshwa mubice byinshi.
Ibisobanuro muburyo bwa NDEF nkibyapa byubwenge, inyandiko, URL, nomero zo guhamagara, porogaramu zo gutangiza, ikarita yerekana ikarita, nibindi birashobora kwandikwa muri label ya NFC kubikoresho bifasha NFC gusoma no kubigeraho. Kandi amakuru yanditse arashobora gushishoza no gufungwa kugirango wirinde impinduka mbi kubindi bikorwa.
Isesengura ryo guhitamo ibicuruzwa
Chip: Birasabwa gukoresha chip ya NXP NTAG21x. Ibintu byihariye bitangwa na NTAG21x byateguwe kunoza kwishyira hamwe no korohereza abakoresha:
1) Gusoma byihuse imikorere yemerera gusikana ubutumwa bwuzuye bwa NDEF ukoresheje itegeko rimwe gusa rya FAST_READ, bityo bikagabanya ibihe byo gusoma mubidukikije byinshi cyane;
2) Kunoza imikorere ya RF, gutanga ihinduka ryinshi muburyo, ingano no guhitamo ibikoresho;
3) 75 μm IC yububiko bwimbaraga zishyigikira gukora tagi ultra-thin tags kugirango byoroshye kwinjiza mubinyamakuru cyangwa ibyapa, nibindi.;
4） Hamwe na 144, 504 cyangwa 888 bytes yumwanya uhari wabakoresha, abakoresha barashobora guhitamo bakurikije ibyo bakeneye.
Antenna:NFC ikora kuri 13.56MHz, ikoresheje aluminium yogukora coil antenna AL + PET + AL.
Glue:Kuberako ikoreshwa kumanikwa kandi ikintu cyo gushiramo kiroroshye, igiciro gito gishyushye gishushe cyangwa kole yamazi irashobora gukoreshwa.
Ibikoresho byo hejuru: impapuro z'ubuhanzi zirashobora gukoreshwa. Niba amazi adakenewe, ibikoresho bya PET cyangwa PP birashobora gukoreshwa. Icapiro hamwe nicyitegererezo birashobora gutangwa.
3. Kurwanya impimbano
Ikimenyetso cya NFC cyo kurwanya impimbano ni ikirango cya elegitoroniki kirwanya impimbano, gikoreshwa cyane cyane mu kumenya ukuri kw'ibicuruzwa, kurinda ibicuruzwa by’isosiyete bwite, gukumira ibicuruzwa by’ibihimbano birwanya ibicuruzwa ku isoko, no kurengera uburenganzira bw’umuguzi n’inyungu zabo. y'abaguzi.
Ikimenyetso cya elegitoroniki cyo kurwanya impimbano cyashyizwe ku bicuruzwa bipfunyitse, kandi abaguzi barashobora kumenya ikirango cya elegitoroniki cyo kurwanya impimbano binyuze kuri APP kuri telefoni igendanwa ya NFC, kugenzura amakuru y’ukuri, no gusoma amakuru ajyanye n’ibicuruzwa. Kurugero: amakuru yuwabikoze, itariki yumusaruro, aho akomoka, ibisobanuro, nibindi, shishoza amakuru yikimenyetso hanyuma umenye ukuri kwibicuruzwa. Kimwe mu byiza byikoranabuhanga rya NFC nuburyo bworoshye bwo kwishyira hamwe: ibirango bito bya NFC bifite ubugari bwa milimetero 10 kandi birashobora kwinjizwa muburyo butagaragara mubipfunyika ibicuruzwa, imyenda cyangwa amacupa ya vino.
Isesengura ryo guhitamo ibicuruzwa
1.Ubwato: Birasabwa gukoresha FM11NT021TT, ni chip tag yakozwe na Fudan Microelectronics yubahiriza ISO / IEC14443-Porotokole hamwe na NFC Forum Type2 Tag kandi ifite ibikorwa byo gutahura. Irashobora gukoreshwa cyane mubice nko gupakira ubwenge, ibintu birwanya impimbano, no gukumira ubujura bwibintu.
Kubirebana n'umutekano wa chip ya NFC ubwayo:
1) Buri chip ifite 7-byte yigenga ya UID, kandi UID ntishobora kongera kwandikwa.
2) Agace ka CC gafite imikorere ya OTP kandi irwanya amarira kugirango irinde gufungura nabi.
3) Agace k'ububiko gafite imikorere yo gusoma gusa.
4) Ifite uburyo bwo kubika ijambo ryibanga ririnzwe, kandi umubare ntarengwa wibanga ryibanga urashobora kugereranywa.
Mu gusubiza impimbano zisubiramo ibirango no kuzuza amacupa nyayo na vino yimpimbano, turashobora gukora ibirango byoroshye bya NFC hamwe nigishushanyo mbonera cya tagi, mugihe cyose ibicuruzwa byafunguwe, tagi izacika kandi ntishobora gukoreshwa! Niba tagi yakuweho, tagi izacika kandi ntishobora gukoreshwa niyo yakuweho.
2.Antenna: NFC ikora kuri 13.56MHz kandi ikoresha antenne ya coil. Kugirango bigabanuke, impapuro zikoreshwa nkutwara antenne na chip AL + Impapuro + AL.
3.Ururimi: Koresha uburemere-burekura uburemere bwimpapuro zo hasi, hamwe na kole-irekura urumuri kubintu byimbere. Muri ubu buryo, iyo tagi yakuweho, ibikoresho byimbere nimpapuro zinyuma bizatandukana kandi byangize antene, bigatuma imikorere ya NFC idakora neza.
