Nangona kuthiwa iintlobo ngeentloboIzikena zebhakhowudi ye-2Dokwangoku yongamele i-advanteji, kodwa kwezinye iimeko zosetyenziso, iiskena zebhakhowudi ye-1D zisahleli kwindawo engenakususwa. Nangona uninzi lwe1D ibhakhowudi umpukukuskena iphepha-based, kodwa ukuze kuhlangatyezwane intlawulo yangoku ethandwa kakhulu mobile, kukho ezinye iimodeli 1D CCD bar ikhowudi scanner umpu kwakhona waqala ukuba umsebenzi ukuskena mobile phones kunye nezinye ikhowudi screen electronic.
1.Yintoni i-1D isibane esibomvu sebhakhowudi iskena?
Iibhakhowudi ze-1D ziyipatheni equka imigca ene-dimensional enye kunye nezithuba, kwaye iindidi eziqhelekileyo ziquka i-EAN-13, CODE39, CODE128, njalo njalo.
Umgaqo weteknoloji ye-CCD yokukhangela iteknoloji kukusebenzisa i-beam ebomvu ukuze i-irradiate ibhakhowudi, i-barcode ibonisa ukukhanya okubomvu, kwaye i-scanner ibona utshintsho lokukhanya okubonakalisiweyo nge-sensor photoelectric sensor, kwaye emva koko ichaza ulwazi kwibhakhowudi. Itekhnoloji yokuskena ukukhanya okubomvu iyakhawuleza, ichanekile kwaye izinzile, kwaye ifanelekile kwiindawo ezahlukeneyo zokusebenza.
Iskena sebhakhowudi ye-CCD ye-1D sinoluhlu olubanzi lwezicelo kumashishini ahlukeneyo. Kwishishini lokuthengisa, lingasetyenziselwa ukuthengisa, ulawulo lwempahla kunye nokuskena iilebhile zexabiso. Kumalungiselelo kunye nokugcinwa kwezinto, inokuskena ngokukhawuleza kwaye ilandelele iimpahla. Kukhathalelo lwempilo, kumathala eencwadi nakwezinye iindawo, ingasetyenziselwa ukulandelela nokulawula izinto. Ukwengeza,Izikena zekhowudi ye-CCD ye-1Didlala indima ebalulekileyo kwimveliso, ukuthutha, ukhuseleko lokutya kunye namanye amashishini. Iphucula ukusebenza kakuhle, inciphisa izinga lempazamo yokusebenza ngesandla kunye nokuphucula ukusebenza komsebenzi jikelele.
2.Iimpawu kunye nemingeni yeekhowudi zesikrini
2.1. Ikhowudi yesikrini luhlobo olukhethekileyo lwekhowudi ye-QR eboniswa kwisikrini sesixhobo sombane. Inokuskenwa ukuze ifunde ulwazi lwekhowudi ye-QR kwisikrini. Ikhowudi yeSkrini inoluhlu olubanzi lweemeko zesicelo, kubandakanywa i-e-payment, i-e-ticketing, i-e-identity verification kunye nokunye. Umzekelo, intlawulo yenziwa nguukuskenaikhowudi yesikrini kwifowuni ephathwayo, okanye uqinisekiso lokungeniswa lwenziwa ngokuskena ikhowudi yesikrini kwi-e-tikiti.
2.2. Iimpawu eziphambili zeekhowudi zesikrini zibandakanya ukuchasana okuphantsi, ukubonakalisa kunye neengxaki zokuhlaziya, njl.
Umahluko ophantsi: Ekubeni ukuboniswa kweekhowudi ze-QR kwisikrini kukhawulelwe kukukhanya kunye nokuchasana kwesikrini, ngamanye amaxesha umahluko omnyama nomhlophe weekhowudi ze-QR uphantsi, okwenza kube nzima kwizixhobo zokuskena ukuzibona ngokuchanekileyo.
Ingxaki yokubonakalisa: Ukukhanya kwesikrini kubonakaliswa emva kwesixhobo sokuskena, okwenza kube nzima kwisixhobo sokuskena ukwahlula imida kunye neenkcukacha zekhowudi ye-QR. Oku kunokubangela ukuba ikhowudi yesikrini ingabonwa ngokuchanekileyo sisixhobo sokuskena.
Ingxaki ye-refraction: Ngexesha lenkqubo yokuskena ikhowudi yesikrini, ukukhanya kuhlanjululwa ngamaxesha amaninzi ngesixhobo sokuskena kunye nesikrini, esinokubangela ukuba isixhobo sokuskena singakwazi ukufunda ulwazi kwikhowudi ye-QR ngokuchanekileyo.
2.3. Izikena zebhakhowudi zeCCD zemveli ze-1D zijongene nemingeni emininzi xa ziskena iikhowudi zesikrini.
Umceli mngeni osezantsi wokuchasana: Izikena zebhakhowudi zeCCD zesiqhelo ze-1D zisenokungakwazi ukufunda iikhowudi ezinomthelekiso ophantsi weskrini. Kuba ukuboniswa kweekhowudi zesikrini kukhawulelwe kukuqaqamba kunye nokuchasana kwesikrini, isixhobo sokuskena sisenokungakwazi ukubamba ngokuchanekileyo kunye nokucacisa ulwazi kwikhowudi ye-2D.
Ukuphonononga kunye nemiceli mngeni yokuhlaziya: Ukukhanya okuvela kwiikhowudi zesikrini kubonakaliswa kwaye kuhlaziywe, nto leyo eyenza kube nzima kwiskena ukufunda ngokuchanekileyo iikhowudi zeQR. ICCD yesiNtuIzikena zebhakhowudi ye-1Dngokwesiqhelo ziyilelwe ukuskena iibhakhowudi zephepha kwaye zisenokungakwazi ukujongana ngokufanelekileyo nokubonisa kunye nemiba yokuchaneka kweekhowudi zesikrini.
Ukoyisa le mingeni, ngoku kukho izixhobo ezenzelwe ngokukodwa ukuskena iikhowudi zesikrini, ezinjeIiskena ze-2Dokanye izikena ezikhethekileyo zekhowudi yesikrini. Ezi zixhobo zisebenzisa itekhnoloji yokuskena ephucukileyo ukubamba ngcono kunye nokucacisa ulwazi kwiikhowudi zesikrini.
Ukuba unomdla okanye umbuzo ngexesha lokukhetha okanye ukusetyenziswa kwaso nasiphi na iskena sebhakhowudi, nceda Cofa ikhonkco elingezantsi thumela umbuzo wakho kwiposi yethu esemthethweni.(admin@minj.cn)ngqo!MINJCODE uzibophelele kuphando kunye nophuhliso lwetekhnoloji yesikena sebhakhowudi kunye nezixhobo zokusebenza, inkampani yethu ineminyaka eli-14 yamava oshishino kwiinkalo zobungcali, kwaye yamkelwa kakhulu luninzi lwabathengi!
