2D kode yumurongo.Mu ikusanyamakuru, ibisobanuro bya '0' na '1' bit bitemba, bigizwe na logique y'imbere ya mudasobwa, bikoreshwa mubwenge.Imiterere myinshi ya geometrike ihuye na binary ikoreshwa muguhagararira amakuru yumubare winyandiko, kandi amakuru ahita atunganywa mu buryo bwikora bwo gusoma mu buryo bwikora igikoresho cyinjiza amashusho cyangwa igikoresho cyo gusikana amafoto.Ifite bimwe mubisanzwe biranga tekinoroji yumurongo: buri code ifite imiterere yihariye.Buri nyuguti ifite ubugari runaka.Ifite imikorere runaka yo kugenzura.Muri icyo gihe, ifite kandi imikorere yo kumenyekanisha mu buryo bwikora imirongo itandukanye yamakuru no gutunganya ibishushanyo mbonera byerekana impinduka.
2D code nuburyo bwimiterere yimibare yimibare irenze 1d code.1d kode irashobora kwerekana gusa amakuru mubyerekezo kimwe (muri rusange icyerekezo gitambitse), mugihe 2d code ishobora kubika amakuru mubyerekezo bitambitse kandi bihagaritse.1d code irashobora kuba igizwe gusa nimibare ninyuguti, mugihe 2d code irashobora kubika amakuru nkinyuguti zishinwa, imibare namashusho, bityo ikibanza cyo gusaba cya 2d kode nini cyane.
Ukurikije ihame rya 2d code, kode-ebyiri-ebyiri irashobora kugabanywamo ibyiciro bibiri: kode ya matrix 2d hamwe na code / umurongo 2d code.
Kode ya Matrix 2d kode ya Matrix 2d, izwi kandi nka chessboard 2d code, yashizwe mumwanya urukiramende mugukwirakwiza gutandukanye kwa pigiseli yumukara numweru muri matrix.Muburyo buhuye nibintu bya matrix, binary '1' igereranwa nigaragara ryamanota (amanota kare, ingingo zizunguruka cyangwa izindi shusho), naho binary '0' ntabwo ihagarariwe no kugaragara kw amanota.Uruhushya no guhuza amanota bigena ibisobanuro byerekanwe na matrix 2d barcode.Matrix 2d kode yumurongo nubwoko bushya bwibishushanyo mbonera byerekana ibimenyetso no gutunganya kode ishingiye kuri tekinoroji yo gutunganya amashusho ya mudasobwa hamwe nihame rya code.Abahagarariye matrix 2d barcode ni QR Code, Data Matrix, MaxiCode, Han Xin Code, Grid Matrix, nibindi.
QR Code
QR Code nigisubizo cyihuse kode ya matrix yihuse, izwi kandi nka Denso QR Code.Ni kode ya matrix 2d isanzwe yemewe nimiryango mpuzamahanga, yatunganijwe bwa mbere na Denso, mu Buyapani, muri Nzeri 1994. Igipimo cy’igihugu cy’Ubushinwa cyise kode ya matrix yihuta.Usibye ibiranga kode ya 1d, ifite kandi ibyiza byubushobozi bunini bwamakuru, kwiringirwa cyane, umwanya muto, akazi keza, gutunganya neza amakuru yinyandiko zitandukanye, gushyigikira 360 ° kode yo gusoma uko bishakiye, ubushobozi bwo gukosora amakosa, hamwe nibanga rikomeye no kurwanya impimbano.Shyigikira inyuguti za ASCII ninyuguti nini za ASCII.
Micro QR nuburyo bushya bwa 2d coding bwatanzwe muri ISO: 2006, busa na QR.Ariko, ugereranije na QR 2d code, Micro QR ifite ibiranga bikurikira: hakenewe ikimenyetso kimwe gusa cyo gushakisha, kandi amajwi ni mato.
Matrix
Data Matrix, mbere yiswe Data code, yahimbwe na International Data Matrix (ID Matrix) mu 1989. Data Matrix irashobora kugabanywa muri ECC000-140 na ECC200, ECC200 ikoreshwa cyane.Data Matrix ishyigikira inyuguti za ASCII ninyuguti nini za ASCII.ni Byakoreshejwe Muburyo Buke Ibicuruzwa Urutonde Umubare.
Grid Matrix
Grid Matrix, yitwa code ya GM, ni kare 2d code.Igishushanyo kode igizwe na kare ya macro module, kandi buri macro module igizwe na 6 × 6 kare.
Ikurikiranyabihe / umurongo wa 2d kode
Gutondekanya / umurongo-ugereranije 2d kode yumurongo nayo yitwa stacking 2d bar code cyangwa layer-parallel 2d bar code.Ihame ryacyo rya code rishingiye kuri 1d bar code, ishyizwe mumirongo ibiri cyangwa myinshi nkuko bikenewe.Iragwa bimwe mubiranga kode ya 1d muburyo bwa code, ihame ryo kugenzura nuburyo bwo gusoma.Ibikoresho byo gusoma birahujwe no gucapa kode yumurongo hamwe na tekinoroji ya 1d.Ariko, kubera ubwiyongere bwumubare wumurongo, birakenewe kumenya umurongo, kandi decoding algorithm ntabwo ihwanye neza na software.Umurongo uhagarariye ubwoko bwa 2d kode yumurongo: PDF417 (ikoreshwa cyane), Micro PDF417, Code 16K, CODABLOCK F, Code 49, nibindi.
PDF 417
PDF417 kuri ubu niyo ikoreshwa cyane kode ya 2d code.Kode yumurongo nubwoko bwimyanya ndende ya code, mukarere kamwe kurenza 2d code isanzwe irashobora kwakira amakuru menshi.Byakoreshejwe cyane mumatike ya tombora, amatike yindege, amashusho yo gusoma.
