Nkhani

Pankhani ya Wireless Radio Frequency Identification, ma frequency omwe amagwira ntchito ndi 125KHZ, 13.56MHz, 869.5MHz, 915.3MHZ, 2.45GHz etc, ofanana ndi: low frequency (LF), high frequency (HF), ultra high frequency (UHF), microwave (MW).Chizindikiro chilichonse cha band frequency chimakhala ndi protocol yofananira: mwachitsanzo, 13.56MHZ ili ndi ISO15693, 14443 protocol, ndipo ma ultra-high frequency (UHF) ali ndi miyezo iwiri yosankha.Imodzi ndi ISO18000-6B, ndipo ina ndi EPC C1G2 muyezo umene wavomerezedwa ndi ISO monga ISO18000-6C.

ISO18000-6B muyezo

Zinthu zazikuluzikulu za muyezowu ndi izi: mulingo wokhwima, chinthu chokhazikika, komanso kugwiritsa ntchito kwakukulu;Nambala ya ID ndi yapadera padziko lonse lapansi;werengani nambala ya ID poyamba, kenako werengani dera la data;mphamvu yayikulu ya 1024bits kapena 2048bits;malo akuluakulu ogwiritsira ntchito 98Bytes kapena 216Bytes;ma tag angapo nthawi imodzi Werengani, mpaka ma tag angapo amatha kuwerengedwa nthawi imodzi;Kuthamanga kwa data ndi 40kbps.

Malinga ndi mawonekedwe a muyezo wa ISO18000-6B, potengera liwiro la kuwerenga ndi kuchuluka kwa zolemba, zolemba zomwe zimagwiritsa ntchito muyezo wa ISO18000-6B zimatha kukwaniritsa zofunikira pamapulogalamu okhala ndi zofunikira zochepa zamalebulo monga bayonet ndi ntchito za doko.Zolemba zamagetsi zomwe zimatsata muyezo wa ISO18000-6B ndizoyenera kuyang'anira zowongolera zotsekeka, monga kasamalidwe ka katundu, zolemba zamagetsi zopangidwa m'nyumba zozindikiritsa ziwiya, zilembo zamalayisensi amagetsi, ndi ziphaso zamagetsi zamagetsi (makadi oyendetsa), ndi zina zambiri.

Zolakwika za muyezo wa ISO18000-6B ndi: chitukukocho chakhala chokhazikika m'zaka zaposachedwa, ndipo chasinthidwa ndi EPC C1G2 m'mapulogalamu ambiri;mapulogalamu kuchiritsa ukadaulo wa deta wosuta si okhwima, koma mu nkhani iyi, deta wosuta akhoza ophatikizidwa ndi kuthetsedwa ndi opanga chip ndi.

ISO18000-6C (EPC C1G2) muyezo

Mgwirizanowu ukuphatikizanso kuphatikizika kwa Class1 Gen2 yomwe idakhazikitsidwa ndi Global Product Code Center (EPC Global) ndi ISO/IEC18000-6 yoyambitsidwa ndi ISO/IEC.Makhalidwe a muyezo uwu ndi: kuthamanga, kuchuluka kwa data kumatha kufika 40kbps ~ 640kbps;chiwerengero cha ma tag omwe amatha kuwerengedwa nthawi imodzi ndi chachikulu, mwachidziwitso ma tag opitilira 1000 amatha kuwerengedwa;choyamba werengani nambala ya EPC, nambala ya ID ya tag iyenera kuwerengedwa ndi kuwerenga kwa data Mode;ntchito yamphamvu, njira zambiri zotetezera kulemba, chitetezo champhamvu;madera ambiri, ogawidwa m'dera la EPC (96bits kapena 256bits, akhoza kuwonjezeredwa ku 512bits), malo a ID (64bit kapena 8Bytes), malo ogwiritsira ntchito (512bit kapena 28Bytes)), malo achinsinsi (32bits kapena 64bits), ntchito zamphamvu, njira zambiri zolembera. , ndi chitetezo champhamvu;komabe, zolemba zoperekedwa ndi opanga ena alibe malo ogwiritsira ntchito deta, monga zolemba za Impinj.

Chifukwa muyezo wa EPC C1G2 uli ndi zabwino zambiri monga kusinthasintha kwamphamvu, kutsata malamulo a EPC, mtengo wotsika wazinthu, komanso kuyanjana kwabwino.Ndizoyenera makamaka kuzindikiritsa kuchuluka kwa zinthu zomwe zili m'munda wa mayendedwe ndipo zikukula mosalekeza.Pakali pano ndi muyezo waukulu wa ntchito za UHF RFID, ndipo amagwiritsidwa ntchito kwambiri m'mabuku, zovala, malonda atsopano ndi mafakitale ena.

Miyezo iwiriyi ili ndi ubwino wake.Mukamapanga pulojekiti yophatikiza, muyenera kuwafanizira molingana ndi njira yanu yogwiritsira ntchito kuti musankhe mulingo woyenera.
