Tanthauzo lofunikira la khadi lowongolera mwayi wolowera njira yoyambira yolowera mwanzeru imakhala ndi wolandila, wowerenga makhadi ndi loko yamagetsi (onjezani kompyuta ndi chosinthira cholumikizira mukalumikizidwa ndi netiweki). Wowerenga makhadi ndi njira yowerengera khadi yosalumikizana, ndipo mwiniwake khadiyo atha kungoyika khadilo mwa wowerenga Wowerenga khadi la Mifare amatha kuzindikira kuti pali khadi ndikutsogolera chidziwitso (nambala yamakhadi) m'khadi kwa wolandirayo. Wolandira alendoyo amayang'ana kaye kuti khadilo ndi loletsedwa, ndiyeno amasankha kutseka chitseko. Njira zonse zimatha kukwaniritsa ntchito zowongolera zolowera malinga ngati zili mkati mwa kusuntha kwamakhadi kovomerezeka. Wowerenga makhadi amaikidwa pakhoma pambali pa khomo, zomwe sizimakhudza ntchito zina. Ndipo kudzera pa adaputala yolumikizirana (RS485) ndi kompyuta yowunikira nthawi yeniyeni (zitseko zonse zitha kutsegulidwa / kutsekedwa ndi malamulo apakompyuta, ndipo mawonekedwe a zitseko zonse amatha kuwonedwa munthawi yeniyeni), kusamvana kwa data, kufunsa, kulowetsa lipoti, ndi zina.

Themwayi khadindi khadi lomwe limagwiritsidwa ntchito munjira yolowera, monga chiphaso, khadi yolowera, khadi yoyimitsa magalimoto, khadi ya umembala, ndi zina zambiri; Khadi lofikira lisanaperekedwe kwa wogwiritsa ntchito, limayikidwa ndi woyang'anira dongosolo kuti adziwe malo omwe angagwiritsidwe ntchito ndi ufulu wa ogwiritsa ntchito, ndipo wogwiritsa ntchito atha kugwiritsa ntchitomwayi wowongolera khadiimasunthidwa kuti ilowe m'dera loyang'anira, ndipo ogwiritsa ntchito omwe alibe khadi lolowera kapena osaloledwa sangathe kulowa m'dera loyang'anira.

Ndi kulimbikitsidwa kosalekeza kwa chidziwitso cha kasamalidwe ka makampani, zitsanzo zoyendetsera ntchito pogwiritsa ntchito makhadi zikufalikira. Makhadi a barcode, maginito maginito makadi, ndi ma ID makadi, monga njira zolondera, zowongolera njira, zowonongera, zoimika magalimoto, kasamalidwe ka makalabu, ndi zina zotere, zimagwira ntchito zawo zapadera kunja kwa oyang'anira madera anzeru. Komabe, monga momwe kasamalidwe ka makhadi kasamalidwe kamakhala kosasunthika, chifukwa zolephera za ntchito zamakadi sizingakwaniritse zosowa za khadi yonse, ndikofunikira kuwonjezera makhadi kwa eni ake nthawi ndi nthawi kuti akwaniritse zosowa za. kasamalidwe ka katundu, monga makhadi olowera, makhadi opangira, makhadi owongolera mwayi, makhadi oyimika magalimoto, makhadi umembala, ndi zina zambiri, sikuti kumangowonjezera ndalama zoyendetsera, komanso kumawonjezera zovuta kuti eni ake azitha kuyang'anira makhadi a aliyense, nthawi zina ngakhale ”ochuluka kwambiri. makadi". Chifukwa chake, pakutha, pambuyo pa 2010, mitundu yamakadi akuluakulu iyenera kukhala YakeMifarekadi, koma kukula kwa CPU khadi kumakhalanso mofulumira kwambiri, zomwe ndizochitika. Mifare khadi ndi mwayi Control RFID Key unyolo ali osiyanasiyana ntchito. Kumbali imodzi, chitetezo chake ndi chachikulu; kumbali ina, imabweretsa mwayi kwa onse-mu-modzi khadi. Munda, kugwiritsa ntchito, kupezeka, kulondera, njira yanzeru, ndi zina zambiri zimaphatikizidwa mu dongosolo limodzi, ndipo ntchito za makadi onse mumodzi zitha kuchitika popanda intaneti.

Mfundoyi ndi chifukwa pali chip chotchedwa RFID mkati. Tikadutsa wowerenga makhadi ndi khadi lomwe lili ndi chipangizo cha RFID, mafunde amagetsi opangidwa ndi owerenga makhadi ayamba kuwerenga zomwe zili mukhadilo. Zomwe zili mkati sizimangowerengedwa, komanso zimatha kulembedwa ndikusinthidwa. Choncho, chip khadi si kiyi yekha, komanso pakompyuta ID khadi kapena Control kupezaRFID Key unyolo.

Chifukwa bola mukamalemba zambiri zanu mu chip, mutha kudziwa yemwe amalowa ndi kutuluka pa owerenga makhadi.
Ukadaulo womwewo umagwiritsidwanso ntchito pothana ndi kuba m'malo ogulitsira ndi zina zotero.

Pali mitundu yambiri ya makhadi owongolera mwayi, omwe amatha kugawidwa m'magulu angapo malinga ndi zida zosankhidwa. Zitsanzo za magulu a makadi owongolera omaliza:
Malinga ndi mawonekedwe
Malingana ndi mawonekedwe, amagawidwa kukhala makhadi okhazikika ndi makadi ooneka ngati apadera. Khadi muyezo ndi yunifolomu kukula khadi mankhwala, ndi kukula kwake ndi 85.5mm×54mm×0.76mm. Masiku ano, kusindikiza sikuli kokha ndi kukula chifukwa cha zosowa za munthu payekha, zomwe zachititsa kuti pakhale makadi "odabwitsa" amitundu yonse m'mayiko padziko lonse lapansi. Makhadi amtunduwu timawatcha kuti makadi ooneka ngati apadera.
Mwa mtundu wa khadi
a) Maginito khadi (ID khadi): Ubwino ndi mtengo wotsika; khadi limodzi pa munthu, chitetezo ambiri, akhoza olumikizidwa kwa kompyuta, ndipo ali khomo kutsegulira mbiri. Choyipa ndichakuti khadi, zida zavala, ndipo moyo ndi waufupi; khadi ndi yosavuta kukopera; sikophweka kulamulira njira ziwiri. Zambiri zamakhadi zimatayika mosavuta chifukwa cha maginito akunja, kupangitsa khadi kukhala yosavomerezeka.
b) Khadi la mawayilesi a wailesi (IC khadi): Ubwino wake ndikuti khadi silimalumikizana ndi chipangizocho, kutsegula chitseko ndikosavuta komanso kotetezeka; moyo wautali, ongolankhula deta osachepera zaka khumi; chitetezo chapamwamba, chikhoza kulumikizidwa ndi kompyuta, ndi mbiri yotsegula chitseko; akhoza kukwaniritsa njira ziwiri; khadi ndizovuta Ndi kukopera. Choyipa chake ndikuti mtengo wake ndi wapamwamba.
Malinga ndi mtunda wowerengera
1. Khadi lothandizira kulowa mumtundu wolumikizana, khadi lolowera liyenera kulumikizana ndi owerenga khadi kuti amalize ntchitoyi.
2, Khadi lowongolera mwayi wolowera, khadi yowongolera mwayi imatha kumaliza ntchito yosinthira khadi mkati mwa makina owongolera olowera.

Makhadi owongolera mwayi ndiwo makamaka mitundu iyi yamakhadi: EM4200 khadi, Access Control RFID

Keyfobs, Mifare khadi, TM khadi, CPU khadi ndi zina zotero. Pakadali pano, makhadi a EM 4200 ndi makhadi a Mifare amatenga pafupifupi msika wonse wogwiritsa ntchito makhadi. Chifukwa chake, tikasankha khadi yofunsira, ndi bwino kusankha EM khadi kapena Mifare khadi ngati khadi lathu lalikulu. Chifukwa kwa makhadi ena omwe sagwiritsidwa ntchito kawirikawiri, kaya ndi kukhwima kwa teknoloji kapena kufanana ndi zipangizo, zidzatibweretsera mavuto ambiri. Ndipo chifukwa cha kuchepa kwa msika, makhadiwa sangachoke pang'onopang'ono pamsika wathu pakapita nthawi. Pamenepa, kukonzanso, kukulitsa, ndi kusintha kwa kayendetsedwe ka njira zopezera mwayi kudzabweretsa zovuta zosayembekezereka.
M'malo mwake, pamagwiritsidwe wamba owongolera mwayi, EM khadi mosakayikira ndi mtundu wothandiza kwambiri wamakhadi owongolera. Amadziwika ndi mtunda wautali wowerengera makadi, kuchuluka kwa msika, komanso machitidwe okhwima aukadaulo. Koma choyipa chachikulu cha mtundu uwu wa khadi ndikuti ndi khadi lowerengera lokha. Ngati tili pachipata ndipo tikusowa zolipiritsa kapena zogulitsira, ndiye kuti khadi yamtunduwu ilibe mphamvu pang'ono.
Kwa ogwiritsa ntchito omwe ali ndi zosowa zowongolera kugwiritsa ntchito, ngati zolemba zina zosavuta kapena kusamutsa zikufunika, ndiye kuti khadi ya Mifare ndiyokwanira. Zachidziwikire, ngati tikufunabe zambiri zozindikiritsa zomwe zili kapena zochitika pakugwiritsira ntchito makina owongolera, ndiye kuti khadi ya CPU yothandizidwa ndiukadaulo waposachedwa ili ndi chitetezo champhamvu kuposa khadi lakale la Mifare. M'kupita kwa nthawi, makhadi a CPU akuwononga kwambiri msika wa Mifare.
