Kukho iindidi ezimbini jikelele zebhakhowudi: one-dimensional (1D okanye linear) kunye ne-two-dimensional (2D). Zisetyenziswa kwiintlobo ezahlukeneyo zezicelo, kwaye kwezinye iimeko ziskenwa kusetyenziswa iintlobo ezahlukeneyo zobuchwepheshe. IUmahluko phakathi kwe-1D kunye ne-2D yebhakhowudi yokuskena ixhomekeke kuyilo kunyeisixa sedatha enokugcinwa kuyo nganye, kodwa zombini zingasetyenziswangempumelelo kwiintlobo ngeentlobo zokuchonga izicelo ezizenzekelayo.
Ukuskena iBhakhowudi ye-1D:
Umgca okanyeIikhowudi zebhakhowudi ze-1D, njengekhowudi ye-UPC efunyanwa rhoqo kumthengiiimpahla, sebenzisa uthotho lwelayini ezinobubanzi obuguquguqukayo kunye nezithuba ukufaka ikhowudi kwidatha -into abantu abaninzi abanokucinga ngayo xa besiva “ibhakhowudi”. Umgcaiibarcodes zibamba nje ishumi elinesibini labasebenzi, kwaye ngokubanzi ukufumana ngokwasemzimbeniixesha elide njengoko iinkcukacha ezininzi zongezwa. Ngenxa yoko, abasebenzisi ngokuqhelekileyo bayayinciphisaIikhowudi zebhakhowudi ukuya kwiimpawu ezi-8-15.
Izikena zebhakhowudi zifunde iibhakhowudi ze-1D ngokuthe tye.Ibhakhowudi ye-laser ye-1Diiskenazezona skena zixhaphakileyo, kwaye zingena ngokwesiqhelo kwi"umpu" imodeli. Ezi skena akufuneki ukuba zinxibelelane ngokuthe ngqo nebhakhowudi ye-1D ukuze zisebenze ngokufanelekileyo, kodwa ngokuqhelekileyo kufuneka zibe kuluhlu lwe-4.ukuya kwi-intshi ezingama-24 ukuskena.
Iibhakhowudi ze-1D zixhomekeke kuqhagamshelo lwedathabheyisi ukuze lube nentsingiselo. Ukuba uskena ikhowudi ye-UPC, umzekelo, abalinganiswa bebhakhowudi kufunekanxulumana nento ekwisiseko sedatha samaxabiso ukuze ibe luncedo. Ezi nkqubo zebhakhowudiziyimfuneko kubathengisi abakhulu, kwaye inokunceda ukwandisa ukuchaneka kwe-inventrikwaye ugcine ixesha.
Ukuskena iBhakhowudi ye-2D:
Iibhakhowudi ze-2D, ezifana neDatha yeMatrix, iKhowudi yeQR okanye iPDF417, zisebenzisa iipateni zezikwere, iihexagons, amachaphaza, kunye nezinye iimilo ukubethelela idatha. Ngenxa yaboubume, iibhakhowudi ze-2D zinokubamba idatha eninzi kuneekhowudi ze-1D (ukuya kuma-2000abalinganiswa), ngelixa bebonakala bebancinci ngokwasemzimbeni. Idatha ifakwe ngekhowudiisekwe kulungiselelo oluthe nkqo noluthe tye lwepateni,ngaloo ndlela ifundwa kumacala amabini.
Iskena sebhakhowudi ye-2D asifakeli nje ulwazi ngealphanumeric.Ezi khowudi zinokuqulatha imifanekiso, iidilesi zewebhusayithi, ilizwi, kunye nezinyeiintlobo zedatha yokubini. Oko kuthetha ukuba unokulusebenzisa ulwazinokuba uqhagamshelwe kuvimba weenkcukacha okanye hayi. Isixa esikhulu seulwazi lunokuhamba ngento ebhalwe ngeIskena sebhakhowudi ye-2D.
Izikena zebhakhowudi ye-2D ziqhele ukusetyenziswa ukufunda iikhowudi zebhakhowudi ze-2D, nangonaezinye iikhowudi ze-2D, njengekhowudi ye-QR eqhelekileyo, zinokufundwangeeapps ezithile ze-smartphone. Izikena zebhakhowudi ze-2D zinokufunda ukusuka ngaphezulu kwe-3iinyawo kude kwaye ziyafumaneka kwisitayile "sompu" esiqhelekileyo, kunye ne-cordless, i-countertop, kunye nezimbo ezinyusiweyo. AbanyeIzikena zekhowudi yebha ye2Dnazoiyahambelana 1D barcodes, ukunika umsebenzisi bhetyebhetye ngakumbi ngendlelazisetyenziswa.
Izicelo ze-1D kunye ne-2D yeTekhnoloji yeBhakhowudi:
Iibhakhowudi ze-1D zinokuskenwa ngeskena selaser yesintu, okanye kusetyenziswaiiskena zemifanekiso esekwe kwikhamera.Iikhowudi ze-2D, kwelinye icala, inokufundwa kuphela kusetyenziswa imifanekiso.
Ukongeza ekubambeni ulwazi oluninzi, iikhowudi zebar ze-2D zinokuba zincinci kakhulu,nto leyo ibenza babe luncedo ekuphawuleni izinto ebezinokubakhoayinakwenzeka kwiilebhile zebhakhowudi ye-1D. Nge-laser etching kunye nezinye iitekhnoloji zokumakisha ezisisigxina, iibhakhowudi ze-2D zisetyenziselwe ukulandelela yonke intoukusuka kwiibhodi ezithambileyo zombane eziprintiweyo zesekethe ukuya kwizixhobo zotyando.
Iibhakhowudi ze-1D, kwelinye icala, zifaneleke kakuhle ekuchongeni izinto ezinokudityaniswa nolunye ulwazi olutshintsha rhoqo. Ukuyaqhubeka ngomzekelo we-UPC, into echongwa yi-UPC ayizukwaziutshintsho, nangona ixabiso laloo nto lihlala linjalo; yiyo loo nto ukudibanisa idatha engatshintshiyo (inombolo yento) kwidatha eguquguqukayo (idathabheyisi yexabiso) yinto engcono kuneekhowudi zolwazi lwexabiso kwibhakhowudi ngokwayo.
Iibhakhowudi ze-2D ziye zasetyenziswa kakhulu kwikhonkco lokubonelela kunyeizicelo zokuvelisa njengoko ixabiso lemifanekiso yeskena liwile. Nguukutshintshela kwiikhowudi zebha ye-2D, iinkampani zinokufaka iinkcukacha ezininzi zemvelisongelixa ukwenza kube lula ukuskena izinto njengoko zihamba kwimigca yendibano okanyeabahambisi - kwaye inokwenziwa ngaphandle kokukhathazeka malunga nesikenaulungelelwaniso.
Oku kuyinyani ngakumbi kwizinto zombane, amayeza, kunye nezonyangoamashishini ezixhobo apho iinkampani zinikwe umsebenzi wokubonelelaisixa esikhulu solwazi lokulandelela imveliso kwezinye izinto ezincinci kakhulu. Umzekelo, imithetho ye-UDI ye-USFDA ifuna amaqhekeza amaninziulwazi lokuvelisa ukuba lubandakanywe kwiintlobo ezithile zonyangoizixhobo. Loo datha inokufakwa ngekhowudi ngokulula kwiibhakhowudi ezincinci ze-2D.
Nangona kukho umahluko phakathiUkuskena ibhakhowudi ye-1D kunye ne-2D, zombiniiintlobo ziluncedo, iindlela eziphantsi ze-encoding data kunye nezinto zokulandelela.Uhlobo lwebhakhowudi (okanye indibaniselwano yebhakhowudi) oyikhethayo iya kuxhomekekakwiimfuno ezithile zesicelo sakho, kubandakanywa uhlobo kunyeIsixa sedatha osifunayo ukuyifaka ikhowudi, ubungakanani be-asethi/into, kunye nendlelanalapho ikhowudi iya kuskenwa khona.
Ukuba unomdla okanye umbuzo ngexesha lokukhetha okanye ukusebenzisa nasiphi na isikena sekhowudi yebar, wamkelekile kuQhagamshelana nathi! MINJCODEuzibophelele kuphando kunye nophuhliso lwekhowudi yebhaiskenaiteknoloji kunye nezixhobo zokusebenza,inkampani yethu ineminyaka eli-14 yamava oshishino kwiinkalo zobungcali, kwaye yamkelwa kakhulu luninzi lwabathengi!
