Kunezigaba ezimbili ezijwayelekile zamabhakhodi: i-one-dimensional (1D noma i-linear) kanye ne-two-dimensional (2D).Zisetshenziswa ezinhlotsheni ezahlukene zezinhlelo zokusebenza, kanti kwezinye ziskenwa kusetshenziswa izinhlobo ezahlukene zobuchwepheshe.Iumehluko phakathi kokuskena kwebhakhodi ye-1D ne-2D uncike kusakhiwo kanyeinani ledatha elingagcinwa kunto ngayinye, kodwa zombili zingasetshenziswangempumelelo ezinhlelweni zokuhlonza ezizenzakalelayo.
Ukuskena kwebhakhodi ye-1D:
Linear nomaAmabhakhodi we-1D, njengekhodi ye-UPC evame ukutholakala kumthengiizimpahla, sebenzisa uchungechunge lwemigqa yobubanzi obuguquguqukayo kanye nezikhala ukuze uhlanganise idatha -lokho abantu abaningi abangacabanga ngakho lapho bezwa “ibhakhodi.”Linearamabhakhodi abamba izinhlamvu ezimbalwa nje ezimbalwa, futhi ngokuvamile athole ngokomzimbaisikhathi eside njengoba idatha eyengeziwe yengezwa.Ngenxa yalokhu, abasebenzisi ngokuvamile banciphisa umkhawulo waboamabhakhodi abe yizinhlamvu eziyi-8-15.
Izikena zebhakhodi zifunda amabhakhodi angu-1D ngokuvundlile.Ibhakhodi ye-laser ye-1Dizikenayizikena ezisetshenziswa kakhulu, futhi ngokuvamile ziza ngo aimodeli "yesibhamu".Lezi zikena azidingi ukuthi zithintane ngqo nebhakhodi ye-1D ukuze zisebenze kahle, kodwa ngokuvamile zidinga ukuba phakathi kwebanga elingu-4.kumayintshi angu-24 ukuze uskene.
Amabhakhodi e-1D ancike ekuxhumekeni kwesizindalwazi ukuze abe nenjongo.Uma uskena ikhodi ye-UPC, isibonelo, izinhlamvu zebhakhodi kufanelezihlobene nento ekusizindalwazi samanani ukuze zibe usizo.Lezi zinhlelo zebhakhodikuyisidingo kubathengisi abakhulu, futhi kungasiza ukukhulisa ukunemba kwempahlafuthi wonge isikhathi.
Ukuskena kwebhakhodi ye-2D:
Amabhakhodi e-2D, njenge-Data Matrix, QR Code noma i-PDF417, asebenzisa amaphethini ezikwele, amahexagoni, amachashazi, nezinye izimo ukuze abhale idatha.Ngenxa yaboisakhiwo, amabhakhodi e-2D angabamba idatha eningi kunamakhodi e-1D (kufika ku-2000izinhlamvu), ngenkathi zisabonakala zizincane ngokomzimba.Idatha ifakwe ikhodingokusekelwe kukho kokubili ukuhlelwa okuqondile nokuvundlile kwephethini,kanjalo ifundwa ngezilinganiso ezimbili.
Iskena sebhakhodi ye-2D asigcini nje ukufaka ikhodi yezinhlamvu nezinombolo.Lawa makhodi angaqukatha izithombe, amakheli ewebhusayithi, izwi, nokunyeizinhlobo zedatha kanambambili.Lokho kusho ukuthi ungasebenzisa ulwazinoma ngabe uxhumeke kusizindalwazi noma cha.Inani elikhuluulwazi lungahamba nento ebhalwe ngokuthi aIskena sebhakhodi ye-2D.
Izikena zebhakhodi ye-2D zivame ukusetshenziselwa ukufunda amabhakhodi e-2D, nakubaamanye amabhakhodi e-2D, njengekhodi ye-QR evame ukubonwa, angafundwangezinhlelo zokusebenza ezithile ze-smartphone.Izikena zebhakhodi ye-2D zingakwazi ukufunda kusukela koku-3izinyawo ezikude futhi zitholakala ngesitayela esivamile "sesibhamu", kanye nezitayela ezingenazintambo, i-countertop, nezitayela ezifakiwe.AbanyeIzikena zekhodi yebha ye-2Dnazoiyahambisana namabhakhodi e-1D, okunikeza umsebenzisi ukuguquguquka okwengeziwe kokuthi abenza kanjanizisetshenziswa.
Izicelo ze-1D kanye ne-2D Barcode Technology:
Amabhakhodi e-1D angaskenwa ngezikena ze-laser zendabuko, noma kusetshenziswaizikena zezithombe ezisuselwa kukhamera.Amabhakhodi we-2D, ngakolunye uhlangothi, ingafundwa kuphela kusetshenziswa izithombe.
Ngaphezu kokubamba ulwazi olwengeziwe, amakhodi ebha ye-2D angaba mancane kakhulu,okubenza babe usizo ekuphawuleni izinto ebezingaba khonaayisebenzi kumalebula ebhakhodi ye-1D.Nge-laser etching nobunye ubuchwepheshe bokumaka unomphela, amabhakhodi e-2D asetshenziselwe ukulandelela yonke intokusukela kumabhodi esekethe aphrintiwe e-elekthronikhi kuya ezintweni zokuhlinza.
Amabhakhodi e-1D, ngakolunye uhlangothi, afaneleka kahle ukukhomba izinto ezingase zihlotshaniswe nolunye ulwazi olushintsha njalo.Kuyaqhubeka nesibonelo se-UPC, into ekhonjwa yi-UPC ngekeukushintsha, nakuba intengo yaleyo nto ivame ukushintsha;yingakho ukuxhumanisa idatha emile (inombolo yento) kudatha eguquguqukayo (isizindalwazi samanani) kuyinketho engcono kunombhalo wekhodi wolwazi lwentengo kubhakhodi ngokwayo.
Amabhakhodi e-2D asetshenziswa kakhulu echungechungeni lokunikezela kanyeukukhiqiza izicelo njengoba izindleko zokuthwebula izithombe zehlile.Nguukushintshela kumakhodi ebha e-2D, izinkampani zingafaka idatha yomkhiqizo eyengeziwengenkathi yenza kube lula ukuskena izinto njengoba zihamba emigqeni yomhlangano nomaamaconveyors - futhi kungenziwa ngaphandle kokukhathazeka ngesithwebuliukuqondanisa.
Lokhu kuyiqiniso ikakhulukazi kuma-electronics, ekhemisi, nakwezokwelaphaizimboni zemishini lapho izinkampani zinikezwe umsebenzi wokuhlinzekainani elikhulu lolwazi lokulandelela umkhiqizo kwezinye izinto ezincane kakhulu.Isibonelo, imithetho ye-UDI ye-USFDA idinga izingcezu ezimbalwa zeulwazi lokukhiqiza oluzofakwa ezinhlotsheni ezithile zezokwelaphaamadivaysi.Leyo datha ingafakwa ngekhodi kalula kumabhakhodi amancane kakhulu e-2D.
Nakuba kukhona umehluko phakathiUkuskena ibhakhodi ye-1D ne-2D, kokubiliizinhlobo ziwusizo, izindlela ezingabizi kakhulu zombhalo wekhodi nezinto zokulandelela.Uhlobo lwebhakhodi (noma inhlanganisela yamabhakhodi) owakhethayo kuzoncikangezidingo ezithile zesicelo sakho, okuhlanganisa uhlobo kanyeinani ledatha oyidingayo ukuze ufake ikhodi, usayizi wempahla/into, nokuthi kanjaninalapho ikhodi izoskenwa khona.
Uma unentshisekelo noma umbuzo ngesikhathi sokukhetha noma ukusetshenziswa kwanoma yisiphi isithwebuli sekhodi yebha, wamukelekile kuXhumana nathi! MINJCODEuzibophezele ocwaningweni nasekuthuthukisweni kwebhakhodiisithwebuliubuchwepheshe kanye nemishini yokusebenzisa,inkampani yethu ineminyaka engu-14 yesipiliyoni sembonini emikhakheni yobungcweti, futhi iye yaqashelwa kakhulu iningi lamakhasimende!
