Mwambo MIFARE 1K RFID Tags: OEM Solutions kuchokera Syntek RFID Factory

KugulaMIFARE 1Kma tag a makina omwe alipo kale si mndandanda-zosankha. Lamuloli limakhala lotetezeka kokha pamene gwero la IC, mtundu wa UID, khalidwe la owerenga, deta yamagulu, makiyi, nyumba zomalizidwa ndi zitsanzo zosindikizidwa zavomerezedwa ngati chitsimikiziro chimodzi. Tagi yomwe imayankha owerenga pakompyuta ikhoza kulephera kuwongolera zomwe zikuchitika, ndipo zitsanzo zolondola zitha kupangabe ma encoding okwera mtengo kapena kupeza{3}}vuto lowongolera popanga.

 

Udindo wa Syntek ngati wopanga OEM ndikusandutsa zofunikira pamakinawa kukhala ma tag olamulidwa. Izi zimayamba ndi owerenga komanso owongolera, osati zojambula, mtengo wagawo kapena kuchuluka kwa "1K". Cholinga chake ndi chosavuta: tsimikizirani kuti zimagwirizana musanatseke bili ya zida ndi malangizo ochulukira-pakupanga.

 

 

 

Kodi Order ya MIFARE 1K OEM Imaphatikizaponso chiyani

 

"MIFARE 1K tag" imalongosola banja la IC ndi kalasi yokumbukira; sichimatanthawuza mankhwala omalizidwa. Dongosolo lokonzekera-likufunikanso wopanga IC ndi gawo lake, njira ya UID, kapangidwe ka tinyanga, zomangira, miyeso, kusindikiza, manambala, ma encoding mapu, kiyi{3}}lamulo la kagwiridwe, njira yoyendera ndi katundu.

 

Chidziwitso chomalizidwa chikhoza kukhala PVC khadi, ABS key fob, epoxy tag, wristband kapena inlay. Mafomuwa amatha kugwiritsa ntchito banja la chip lomwelo koma amachita mosiyana chifukwa kukula kwa koyilo, makulidwe a nyumba, njira yolumikizirana, zida zapafupi ndi geometry ya owerenga amasintha kulumikizana kwa RF. The Chip datasheet a labotale ntchito mtunda si lonjezo la anamaliza opatsidwa mu unsembe kasitomala.

 

Kusiyana kumeneku n’kofunika kwambiri makamaka tikamayerekezera mawu ogwidwa mawu. Otsatsa awiri angathe kulemba kuti "MIFARE Classic 1K" pamene akugwira mawu osiyanasiyana a IC, maonekedwe a UID, kukula kwa tinyanga ndi mtundu{2}}kuwongolera kukula kwake. Chifukwa chake, mzere wotsika mtengo ukhoza kuyimira chinthu chosiyana m'malo motsika mtengo womanga womwewo.

 

Pamapulojekiti amtundu wa keychain, chisankho cha nyumba chiyenera kutsatira-mayeso oyika. Nthawi zambiri, kutsekeredwa ndi kuyika chizindikiro kumayenderana, koma mafotokozedwe a projekiti ayenera kutchulabe mbiri yeniyeni.

 

MIFARE Classic 1K Imapereka Pafupifupi 752 Mabyte Ogwiritsidwa Ntchito

 

Memory ya MIFARE Classic 1K ndi pafupifupi ma 752 byte pamagwiritsidwe wamba, osati ma byte 1,024 athunthu.IC ili ndi magawo 16 okhala ndi midadada inayi ya 16-byte pagawo lililonse. M'gawo lililonse, chipika chimodzi ndi Sector Trailer yosungidwa kwa Key A, mikhalidwe yofikira ndi Key B kapena kugwiritsa ntchito pulogalamuyo pansi pazikhazikiko zofikira. Manufacturer Block 0 mu Sector 0 sichimakumbukiranso ogwiritsa ntchito wamba.

 

Kuwerengera kowonekera bwino ndi:

 

Chinthu chokumbukira	Kuwerengera	Ma Byte omwe amapezeka pazantchito wamba
Chikumbukiro chonse chakuthupi	64 midadada × 16 byte	1,024
Makumi asanu ndi limodzi a Sector Trailers	16 midadada × 16 byte	−256
Manufacturer Block 0	1 block × 16 mabayiti	−16
Pafupifupi malo ogwiritsira ntchito	47 midadada × 16 byte	752

 

Nambala iyi imalepheretsa cholakwika chodziwika bwino: kupanga mapu ogwiritsira ntchito 1,024-byte ndikuzindikira panthawi ya encoding kuti makiyi ndi mikhalidwe yofikira imakhala gawo la kukumbukira. Maonekedwe enieni a gawo, mitengo yosungidwa, zowerengera ndi macheki ziyenera kulembedwa musanayambe kusindikiza zitsanzo. Kufotokozera kwathunthu kulipo m'nkhani yomwe ilipoKukumbukira kwa MIFARE 1K ndi kapangidwe ka gawo.

 

NXP imatchula nthawi yocheperako yosunga deta ya zaka 10 komanso kupirira kocheperako kwa mizere ya 100,000 pansi pa zomwe zanenedwa ndi datasheet. Ziwerengerozi ndi ziyeneretso zamagulu, osati zitsimikizo pazantchito iliyonse. Ngati chitsimikiziro chidzalembedwanso pafupipafupi, werengerani zolemba pa block iliyonse pa moyo wautumiki womwe mukufuna ndipo yesani ndondomeko yeniyeni ya ndalamazo m'malo monena za kupirira mwadzipatula.

Tchulani IC Yeniyeni Pamaso pa Mawonekedwe a Tag

 

Zogulitsa zotetezeka kwambiri zimatchula wopanga IC, banja lenileni lazogulitsa komanso ma UID ovomerezeka. "Kugwirizana ndi MIFARE 1K" sikufanana ndi "NXP MIFARE Classic EV1 1K." Angatanthauze gulu lachitatu-IC lomwe limagwira ntchito ndi machitidwe osiyanasiyana, kapena chinthu cholembedwanso-chinthu cha UID chopangira labotale kapena kusamuka.

 

IC njira	Kugwiritsa ntchito koyenera	Chofunikira chachikulu chotsimikizira
Genuine NXP MIFARE Classic EV1 1K	Makina oyika omwe amafunikira dzina lotchedwa NXP IC	Tsimikizirani kutsata, njira ya UID ndi mayeso owerenga / owongolera

Udindo wathu wogula ndi wokhazikika: aMIFARE 1K OEM ogulitsaziyenera kusakhazikika kupalibe IC m'malo. Njira ina yovomerezeka ndiyovomerezeka pokhapokha itadziwika ndi wopanga ndi nambala yagawo, chitsanzo chongosindikizidwa chatsopano chikupambana mayeso omwe adagwirizana, zolemba zovomerezeka zimasinthidwa, ndipo wogula akupereka chilolezo cholembedwa.

 

Lamuloli limatseka mpata womwe kuyang'ana kowoneka sikungazindikire. Ma fobs awiri ofunikira atha kugwiritsa ntchito nyumba zofananira ndi kusindikiza pomwe IC yoyambira imasintha machitidwe a UID, kuyankha kotsimikizika kapena kugwirizana ndi malo owerengera omwe kasitomala amatumizidwa. Choncho "zofanana" ziyenera kukhala zotsatira zoyesa ndi kusintha kosayinidwa, osati chizindikiro chogula.

 

Fananizani Njira ya UID ku Reader ndi Controller

 

TheMIFARE Classic 1K 4-byte motsutsana ndi 7-byte UIDchisankho chiyenera kupangidwa motsutsana ndi njira yonse ya dongosolo, osati owerenga yekha. Malo ena osungira cholowa, zida zapakati ndi zowongolera zimangosunga ma UID mabayiti anayi okha ngakhale wowerenga watsopano atha kuzindikira zisanu ndi ziwiri.

 

Gwiritsani ntchito-magawo atatu motsatizana:

 

1. Tsimikizirani kuti owerenga amafotokoza UID yonse nthawi zonse.
2. Tsimikizirani ndikuwerenga gawo lofunikira pogwiritsa ntchito makiyi a projekiti ndi momwe mungafikire.
3. Perekani umboni kwa wowongolera amoyo ndikutsimikizira zomwe zikuchitika, chipika cha zochitika ndi chizindikiritso chosungidwa.

 

NXP imasiyanitsa mitundu yokhazikika komanso yosakhala-zozizindikiritsa zapadera ndipo imalimbikitsa kuti okonza makina azigwira bwino ntchito zautali wa zizindikiritso. Zotsatira zake n'zakuti utali wa UID, ziyembekezo zapadera ndi nkhokwe-kachitidwe kachitidwe ka zinthu zili mu RFQ ndi mbiri ya Golden Sample Record, osati mu imelo yongochitika kumene kupanga kukayamba. (NXP UID application note AN10927)

 

Ngati woyang'anira aloleza kulowa mu UID yekha, kuchotsa mbiri ya 4-byte ndi mtundu wowerengeka wa 7-byte akhozabe kuswa anthu olembetsa kapena kufanana ndi zochitika. Chofunika koposa, chilolezo cha UID chokha sichiyenera kufotokozedwa ngati chitetezo chapakati. Ndikoyenera pokhapokha ngati zotsatira za kukopera chozindikiritsa zimavomerezedwa ngati chiopsezo chochepa.
