Njira yolumikizirana ndiyofunikira kwambiri pakuyika zidziwitso ndi zinthu.Mitundu ya mawonekedwe a owerenga a RFID amagawidwa makamaka m'malo olumikizirana mawaya ndi ma waya opanda zingwe.Malo olumikizirana mawaya nthawi zambiri amakhala ndi njira zosiyanasiyana zolumikizirana, monga: ma serial ports, ma network kapena njira zina zolumikizirana.Opanda zingwe zolumikizira makamaka Lumikizanani ndi WIFI, Bluetooth, etc. Maonekedwe osiyana akhoza kukwaniritsa zosowa zosiyanasiyana ntchito zochitika.

Mtundu wa mawonekedwe a RFID:

1. Kulumikizana ndi mawaya kumaphatikizapo USB, RS232, RS485, Efaneti, TCP/IP, RJ45, WG26/34, mabasi a mafakitale, malo ena opangira deta, ndi zina zotero.

1) USB imatanthawuza "Universal Serial Bus", yomwe imatchedwanso "Serial Line", yomwe ndi mulingo wakunja wamabasi olumikiza makompyuta ndi zida zakunja, komanso ndiukadaulo wamakina olowera ndi zotuluka polumikizira ndi kulumikizana. ndi zida zakunja.Amagwiritsidwa ntchito kwambiri pazinthu zolumikizirana ndi zidziwitso monga makompyuta amunthu ndi zida zam'manja, ndipo amatha kulumikizidwa kwambiri ndi mbewa, kiyibodi, makina osindikizira, makina ojambulira, makamera, ma drive ama flash, mafoni am'manja, makamera a digito, ma hard drive am'manja, ma drive owoneka akunja kapena floppy drives, USB network cards, etc.

2) RS485 imatenga kufalikira koyenera komanso kulandirira kosiyana, kotero imatha kupondereza kusokoneza wamba.Kuphatikiza apo, transceiver ya basi imakhala ndi chidwi chachikulu ndipo imatha kuzindikira ma voltages otsika ngati 200mV, kotero chizindikiro chotumizira chikhoza kubwezeredwa kutali ndi mita masauzande.RS485 imagwiritsa ntchito mawonekedwe a theka-duplex, ndipo mfundo imodzi yokha ndiyo yomwe imatumiza nthawi iliyonse.RS485 ndi yabwino kwambiri yolumikizira mfundo zambiri, yomwe imatha kupulumutsa mizere yambiri yama siginecha.Kugwiritsa ntchito RS485 kumatha kulumikizidwa kuti mupange makina ogawidwa, omwe amalola mpaka 32 madalaivala olumikizirana ofanana ndi olandila 32.Pamene mtunda woyankhulirana ukufunika kukhala makumi a mita kufika masauzande a mamita, RS485 serial bus standard imagwiritsidwa ntchito kwambiri.

3) RS232 pakali pano ndi imodzi mwamayankhulidwe wamba a owerenga RFID.Ndi mawonekedwe amtundu wamtundu wopangidwa ndi American Electronics Industries Association EIA.RS ndiye chidule cha "standard standard" m'Chingerezi, 232 ndi nambala yozindikiritsa, RS232 ndikuwongolera mawonekedwe amagetsi ndi mawonekedwe akuthupi, imangogwira njira yotumizira deta, ndipo sikuphatikiza njira yosinthira deta.Popeza mawonekedwe a mawonekedwe a RS232 adawonekera kale, pali zofooka mwachilengedwe.Popeza RS-232 ndi njira imodzi yotumizira chizindikiro, pali mavuto monga phokoso lodziwika bwino komanso kusokoneza wamba;ndipo mtunda wotumizira ndi waufupi, womwe umagwiritsidwa ntchito mkati mwa 20m Communication;mlingo wa kufala ndi otsika, mu asynchronous kufala, mlingo wa baud ndi 20Kbps;mtengo wa chizindikiro cha mawonekedwe ndipamwamba, ndipo chip cha mawonekedwe ozungulira ndi osavuta kuonongeka.

4) Efaneti amagwira ntchito pansi wosanjikiza, womwe ndi wosanjikiza ulalo deta.Efaneti ndi ambiri ntchito m'dera maukonde, kuphatikizapo Efaneti muyezo (10Mbit/s), Fast Efaneti (100Mbit/s) ndi 10G (10Gbit/s) Efaneti.Si maukonde enieni, koma mafotokozedwe aukadaulo.Muyezo uwu umatanthawuza mtundu wa chingwe ndi njira yopangira ma siginecha omwe amagwiritsidwa ntchito pa netiweki yapafupi (LAN).Efaneti imatumiza mapaketi azidziwitso pamlingo wa 10 mpaka 100 Mbps pakati pa zida zolumikizidwa.Chingwe chopotoka 10BaseT Efaneti chakhala ukadaulo wa Efaneti wogwiritsidwa ntchito kwambiri chifukwa cha mtengo wake wotsika, kudalirika kwakukulu komanso liwiro la 10Mbps.

5) TCP/IP ndi protocol yolumikizirana ndi intaneti, yomwe imadziwikanso kuti network network network.Ndilo protocol yoyambira pa intaneti komanso maziko a intaneti.TCP/IP imatanthawuza momwe zida zamagetsi zimalumikizirana ndi intaneti komanso momwe deta imafalikira pakati pawo.Protocol imatengera dongosolo la 4-layer hierarchical, ndipo gawo lililonse limayitanitsa protocol yoperekedwa ndi gawo lake lotsatira kuti likwaniritse zosowa zake.M'mawu a layman, TCP ili ndi udindo wozindikira zovuta zopatsirana, kutumiza chizindikiro pakakhala vuto, ndikufunika kutumizidwanso mpaka deta yonse itatumizidwa kumalo komwe ikupita.

6) Mawonekedwe a RJ45 nthawi zambiri amagwiritsidwa ntchito potumiza deta, ndipo kugwiritsa ntchito kofala kwambiri ndi mawonekedwe a makadi a netiweki.RJ45 ndi mtundu wa zolumikizira zosiyanasiyana.Pali njira ziwiri zosinthira zolumikizira za RJ45 molingana ndi mzere, umodzi ndi lalanje-woyera, lalanje, wobiriwira-woyera, wabuluu, wabuluu-woyera, wobiriwira, wofiirira-woyera, wofiirira;winayo ndi wobiriwira-woyera, wobiriwira, walalanje-woyera, wabuluu, wabuluu-woyera, walalanje, wabulauni-woyera, ndi wabulauni;choncho, pali mitundu iwiri ya mizere yogwiritsira ntchito zolumikizira za RJ45: mizere yowongoka ndi mizere yopingasa.

7) Protocol ya Wiegand ndi muyezo wogwirizana padziko lonse lapansi ndipo ndi njira yolumikizirana yopangidwa ndi Motorola.Zimagwiranso ntchito kuzinthu zambiri za owerenga ndi ma tag omwe akukhudzidwa ndi machitidwe owongolera mwayi.Muyezo wa 26-bit uyenera kukhala wogwiritsidwa ntchito kwambiri, ndipo palinso mawonekedwe a 34-bit, 37-bit ndi ena.Mtundu wokhazikika wa 26-bit ndi mawonekedwe otseguka, zomwe zikutanthauza kuti aliyense atha kugula khadi ya HID mumtundu wake, ndipo mitundu yamitundu iyi ndi yotseguka komanso yosankha.Mawonekedwe a 26-Bit ndi omwe amagwiritsidwa ntchito kwambiri pamakampani ndipo ndi otseguka kwa onse ogwiritsa ntchito a HID.Pafupifupi machitidwe onse olowera amavomereza mtundu wa 26-Bit.

2. Mawonekedwe opanda zingwe amagwiritsidwa ntchito kwambiri potumiza deta kumapeto opanda zingwe.Malo ochezera opanda zingwe amaphatikizapo infuraredi, Bluetooth, WIFI, GPRS, 3G/4G ndi ma protocol ena opanda zingwe.

ZosiyanaOwerenga RFIDkuthandizira ma protocol osiyanasiyana ndi machitidwe kutengera momwe amagwiritsidwira ntchito.Mukhoza kusankha chipangizo choyenera malinga ndi zosowa za polojekitiyi.Malingaliro a kampani Shenzhen Handheld-Wireless Technology Co, Ltd.wakhala paokha kupanga ndi kupanga RFID wowerenga m'manja ndi wolemba kwa zaka zoposa khumi, zolumikizira zosiyanasiyana akhoza makonda kukwaniritsa zosowa zanu ntchito.
