amakuru

Kode-ebyiri-kode "intego =" _ ubusa "> Kode-ebyiri-nayo yitwa QR Code, kandi izina ryuzuye rya QR ni Igisubizo cyihuse. Nuburyo bukoreshwa cyane bwa coding kubikoresho bigendanwa mumyaka yashize. Irashobora kubika byinshi Amakuru arashobora kandi kwerekana ubwoko bwamakuru menshi.
Ibice bibiri-byerekana kode / ibice bibiri-byerekana kode (2-yimibare yumurongo) yandika amakuru yikimenyetso cyamakuru hamwe nigishushanyo cyihariye cya geometrike cyatanzwe ku ndege (icyerekezo-cyerekezo) ukurikije amategeko amwe; Ukoresheje ibitekerezo bya "0" na "1" biti bitemba bigize ishingiro ryumvikana rya mudasobwa, ukoresheje imiterere myinshi ya geometrike ihuye na binary kugirango ugaragaze inyandiko namakuru yumubare, gusoma byikora ukoresheje ibikoresho byinjiza amashusho cyangwa ibikoresho byo gusikana amafoto kugirango ugere kubikorwa byikora yamakuru: ifite ibintu bimwe bisanzwe biranga tekinoroji ya barcode: buri code ya sisitemu ifite imiterere yihariye; buri nyuguti ifata ubugari runaka; ifite imikorere runaka yo kugenzura, nibindi. Mugihe kimwe, ifite kandi imikorere yo kumenyekanisha mu buryo bwikora amakuru mumirongo itandukanye, hamwe no gutunganya ibishushanyo mbonera no guhindura ingingo.
Ibiranga
1. Kode yuzuye cyane, ubushobozi bwamakuru menshi: irashobora kwakira inyuguti nkuru zigera kuri 1850 cyangwa nimero 2710 cyangwa 1108 bytes, cyangwa inyuguti zirenga 500 zishinwa, zikaba zikubye inshuro icumi kurenza ubushobozi bwamakuru ya barcode.
2. Urutonde rwagutse rwa code: barcode irashobora gushushanya amashusho, amajwi, inyuguti, umukono, igikumwe nandi makuru yanditswe, kandi ikabigaragaza hamwe na barcode; irashobora kwerekana indimi nyinshi; irashobora kwerekana ishusho yamakuru.
3. Kwihanganira amakosa akomeye no gukosora amakosa: ibi bituma barcode-ibiri-ibiri isomwa neza mugihe yangiritse igice kubera gutobora, kwanduza, nibindi, kandi amakuru arashobora kugarurwa mugihe agace kangiritse kageze kuri 50%.
4. Kwizera kwinshi kwizerwa: Birarenze cyane kurenza ikosa risanzwe rya barcode ikosa rya 2/1000000, kandi ikosa rya biti ntirirenga 1/10000000.
5. Ingamba zo gushishoza zishobora gutangizwa: ibanga no kurwanya impimbano nibyiza.
6. Igiciro gito, cyoroshye gukora, kandi kiramba.
7. Imiterere, ingano nigipimo cyibimenyetso bya barcode birashobora guhinduka.
8. 2D barcode irashobora gusomwa ukoresheje laser cyangwa abasomyi ba CCD.
