Imvelaphi kunye nesicelo
I-NFC: Itekhnoloji yonxibelelwano olungenazingcingo olunomgama omfutshane ovumela ukuhanjiswa kwedatha okungaqhagamshelwanga phakathi kwezixhobo zombane, ukutshintshiselana ngedatha kumgama we-10cm. Inkqubo yonxibelelwano ye-NFC ibandakanya iinxalenye ezimbini ezizimeleyo: umfundi we-NFC kunye nethegi ye-NFC. Umfundi we-NFC yinxalenye esebenzayo yenkqubo "efunda" (okanye iinkqubo) ulwazi ngaphambi kokuqalisa impendulo ethile. Inika amandla kwaye ithumela imiyalelo ye-NFC kwindawo yokwenziwa kwenkqubo (okt i-tag ye-NFC). Ngokuqhelekileyo, ngokubambisana ne-microcontroller, umfundi we-NFC unikezela amandla kunye nokutshintshiselana ngolwazi kunye neleyibhile enye okanye ngaphezulu kwe-NFC. Umfundi we-NFC uxhasa iiprothokholi ezininzi zeRF kunye neempawu kwaye zinokusetyenziswa ngeendlela ezintathu ezahlukeneyo: ukufunda/ukubhala, i-peer-to-peer (P2P) kunye nokulinganisa ikhadi. Ibhendi ye-frequency yokusebenza ye-NFC yi-13.56 MHz, eyeyama frequency aphezulu, kunye nemigangatho yeprotocol yi-ISO/IEC 14443A/B kunye ne-ISO/IEC15693.
Iileyibhile ze-NFC zinoluhlu olubanzi lwezicelo, ezinjengokubhanqa kunye nokulungiswa kweempazamo, iipowusta zentengiso, ukuchasana nomgunyathi, njl.
1.Ukudityaniswa nokulungisa iimpazamo
Ngokubhala ulwazi olufana negama kunye negama lokugqitha le-WiFi kwileyibhile ye-NFC ngokusebenzisa umfundi we-NFC, uncamathisela ileyibhile kwindawo efanelekileyo, uqhagamshelo lunokwenziwa ngokubeka ngokulula izixhobo ezibini ze-NFC ezisondeleleneyo. Ukongeza, i-NFC inokuqalisa ezinye iiprotocol ezifana neBluetooth, iZigBee. Ukubhanqa ngenene kwenzeka ngomzuzwana kwaye i-NFC isebenza kuphela xa uyifuna, ngoko akuyi kubakho naluphi na uqhagamshelo lwesixhobo ngempazamo kwaye akuyi kubakho nakuphi na ukungqubana kwesixhobo njengeBluetooth. Ukugunyazisa izixhobo ezitsha okanye ukwandisa inethiwekhi yakho yasekhaya nako kulula, kwaye akukho mfuneko yokukhangela umdibaniso okanye ufake igama lokugqitha.
Uhlalutyo loKhetho lweMveliso
Itshiphu: Kuyacetyiswa ukuba usebenzise uthotho lwe-NXP NTAG21x, NTAG213, NTAG215 kunye ne-NTAG216. Olu luhlu lweetshiphusi luhambelana nomgangatho we-NFC Uhlobo lwe-2 kwaye ludibana nomgangatho we-ISO14443A.
I-eriyali:I-NFC isebenza kwi-13.56MHz, isebenzisa inkqubo ye-aluminium etching coil i-eriyali AL+PET+AL.
Iglu: Ukuba into emayibanjelwe igudileyo kwaye indawo yokusetyenziswa ilungile, iglu eshushu eshushu ephantsi ngexabiso eliphantsi okanye iglu yamanzi ingasetyenziswa. Ukuba indawo yokusetyenziswa irhabaxa kwaye into ekufuneka ilandelwe irhabaxa, iglu e-oyile ingasetyenziswa ukuyenza yomelele.
Imathiriyeli engaphezulu: Iphepha eligqunyiweyo lingasetyenziswa. Ukuba kufuneka kungangeni manzi, izinto zePET okanye zePP zingasetyenziswa. Umbhalo kunye noshicilelo lwepateni lunokubonelelwa.
2. Intengiso kunye neePowusta
Iipowusta ezihlakaniphile zezinye zezicelo zetekhnoloji ye-NFC. Yongeza iithegi ze-NFC kwiintengiso zephepha lokuqala okanye iibhodi ezinkulu, ukuze xa abantu bebona intengiso, basebenzise ii-smartphones zabo zobuqu ukuskena ithegi ebethelelweyo ukuze bafumane ulwazi olufanelekileyo lwentengiso. Kwintsimi yeepowusta, itekhnoloji ye-NFC inokongeza ukusebenzisana ngakumbi. Umzekelo, ipowusta equlethe itshiphu ye-NFC inokuqhagamshelwa kumxholo onjengomculo, iividiyo, kunye nemidlalo esebenzisanayo, ngaloo ndlela itsala abantu abaninzi ukuba bahlale phambi kwepowusta kunye nokwandisa imbonakalo yebrendi kunye neziphumo zonyuselo. Ngokuthandwa kwee-smartphones ezinemisebenzi ye-NFC, iipowusta ze-NFC ezihlakaniphile zikwasetyenziswa kwiindawo ezininzi.
Ulwazi olukwifomathi ye-NDEF njengeepowusta ezihlakaniphile, okubhaliweyo, ii-URL, iinombolo zokufowuna, ii-apps zokuqalisa, ulungelelwaniso lwemephu, njl. Kwaye ulwazi olubhaliweyo lunokuguqulelwa ngokuntsonkothileyo kwaye lutshixelwe ukunqanda utshintsho olubi ngolunye usetyenziso.
Uhlalutyo loKhetho lweMveliso
Itshiphu: Kuyacetyiswa ukuba usebenzise i-NXP NTAG21x series chips. Iimpawu ezithile ezibonelelwe yi-NTAG21x ziyilelwe ukuphucula indibaniselwano kunye nokulula komsebenzisi:
I-1) Ukusebenza kokuFunda ngokukhawuleza kuvumela ukuskena kwemiyalezo ye-NDEF epheleleyo usebenzisa umyalelo omnye kuphela we-FAST_READ, ngaloo ndlela kuncitshiswa amaxesha okufunda kwiindawo zokuvelisa umthamo ophezulu;
2) Ukuphuculwa kokusebenza kweRF, ukunika ukuguquguquka okukhulu kwimilo, ubungakanani kunye nokukhetha izinto;
3) 75 μm IC ukhetho ubukhulu ixhasa ukwenziwa iithegi ultra-obhityileyo ukudityaniswa lula kwiimagazini okanye iipowusta, njl.;
4) Nge-144, 504 okanye i-888 bytes yendawo yomsebenzisi ekhoyo, abasebenzisi banokukhetha ngokweemfuno zabo.
I-eriyali:I-NFC isebenza kwi-13.56MHz, isebenzisa inkqubo ye-aluminium etching coil i-eriyali AL+PET+AL.
Iglu:Ngenxa yokuba isetyenziswa kwiipowusta kwaye into eza kuncanyathiselwa imtyibilizi ngokwentelekiso, iglu eshushu enyibilikayo enexabiso eliphantsi okanye iglu yamanzi ingasetyenziswa.
Imathiriyeli engaphezulu: iphepha lobugcisa linokusetyenziswa. Ukuba kufuneka kungangeni manzi, izinto zePET okanye zePP zingasetyenziswa. Umbhalo kunye noshicilelo lwepateni lunokubonelelwa.
3. Anti-inkohliso
Ithegi ye-NFC yokuchasana nenkohliso yithegi echasene nenkohliso ye-elektroniki, esetyenziswa ikakhulu ukuchonga ubunyani beemveliso, ukukhusela imveliso yohlobo lwenkampani, ukuthintela iimveliso zomgunyathi ukuba zisasazeke kwimarike, kunye nokukhusela amalungelo abathengi kunye nomdla. yabathengi.
Ileyibhile ye-electronic anti-counterfeiting ifakwe kwi-package yemveliso, kwaye abathengi banokuchonga ileyibhile ye-electronic anti-counterfeiting nge-APP kwi-NFC yefowuni ephathwayo, khangela ulwazi lokunyaniseka, kwaye bafunde ulwazi olunxulumene nemveliso. Umzekelo: ulwazi lomenzi, umhla wemveliso, indawo yemvelaphi, iinkcukacha, njl. njl., cima idatha yethegi kwaye uqinisekise ubunyani bemveliso. Enye yeenzuzo zetekhnoloji ye-NFC kukulula kwayo ukudibanisa: iileyibhile ezincinci ze-NFC zimalunga ne-10 millimeters ububanzi kwaye zinokufakwa ngokungaqhelekanga kwipakethe yemveliso, impahla okanye iibhotile zewayini.
Uhlalutyo loKhetho lweMveliso
1.Itshiphu: Kunconywa ukusebenzisa i-FM11NT021TT, eyi-tag chip ephuhliswe yi-Fudan Microelectronics ehambelana ne-ISO/IEC14443-A protocol kunye ne-NFC Forum Type2 Tag standard kwaye inomsebenzi wokufumanisa ovulekileyo. Ingasetyenziswa ngokubanzi kwiinkalo ezifana nokupakishwa okukrelekrele, izinto ezichasene ne-counterfeiting, kunye nokuthintela ubusela bezinto eziphathekayo.
Ngokumalunga nokhuseleko lwethegi ye-NFC ngokwayo:
1)I-chip nganye ine-UID ye-7-byte ezimeleyo, kwaye i-UID ayinakuphinda ibhalwe.
I-2) Indawo yeCC inomsebenzi we-OTP kwaye ixhathisa ukukrazula ukunqanda ukuvuleka okungalunganga.
3) Indawo yokugcina inomsebenzi wokutshixa wokufunda kuphela.
4) Inomsebenzi wokugcina okhuselweyo owenziwe ngokukhethwa, kwaye inani eliphezulu leenzame zephasiwedi liqwalaselwe.
Ukuphendula iithegi zokuphinda zisetyenziswe kunye nokuzalisa iibhotile zokwenyani ngewayini yobuxoki, sinokuvelisa iilebhile ze-NFC ezibuthathaka ngoyilo lwesakhiwo sethegi, nje ukuba iphakheji yemveliso ivuliwe, ithegi iya kwaphuka kwaye ayinakuphinda isetyenziswe! Ukuba ithegi isusiwe, ithegi iya kwaphulwa kwaye ayinakusetyenziswa nokuba isusiwe.
2.I-eriyali: I-NFC isebenza kwi-13.56MHz kwaye isebenzisa i-eriyali yekhoyili. Ukuze wenze kube buthathaka, isiseko sephepha sisetyenziswa njengomphathi we-antenna kunye ne-chip AL + Paper + AL.
3.Iglu: Sebenzisa iglue enzima kwiphepha elisezantsi, kunye neglue ekhupha ukukhanya kwizinto zangaphambili. Ngale ndlela, xa ithegi ihlanjululwe, izinto zangaphambili kunye nephepha elixhasayo liya kwahlula kwaye lonakalise i-antenna, okwenza umsebenzi we-NFC ungasebenzi.
