Nakuba kuthiwa ezihlukahlukeneIzikena zebhakhodi ze-2Dokwamanje zibusa inzuzo, kodwa kwezinye izimo zokusetshenziswa, izikena zebhakhodi ye-1D zisathatha isikhundla esingenakushintshwa. Nakuba iningi le-Isibhamu sebhakhodi ye-1Dukuskena okusekelwe ephepheni, kodwa ukuze kuhlangatshezwane nenkokhelo yeselula ethandwa kakhulu, kunamanye amamodeli esibhamu sebhakhodi ye-CCD ye-1D nayo yaqala ukuba nomsebenzi wokuskena omakhalekhukhwini namanye amakhodi esikrini se-electronic.
1.Siyini isithwebuli sebhakhodi esikhanyayo esibomvu esingu-1D?
Amabhakhodi e-1D ayiphethini ehlanganisa imigqa ene-dimensional eyodwa nezikhala, futhi izinhlobo ezijwayelekile zifaka i-EAN-13, CODE39, CODE128, njalo njalo.
Umgomo wobuchwepheshe bokuskena be-CCD ukusebenzisa i-beam yokukhanya okubomvu ukuze ukhanyise ibhakhodi, ibhakhodi ikhombisa ukukhanya okubomvu, futhi isithwebuli sibona ushintsho lokukhanya okuveziwe ngenzwa yesithombe kagesi, bese sikhipha ulwazi olukubhakhodi. Ubuchwepheshe bokuskena ukukhanya okubomvu buyashesha, bunembile futhi buzinzile, futhi bufanele izindawo zokusebenza ezihlukahlukene.
Iskena sebhakhodi ye-CCD ye-1D sinezinhlobonhlobo zezinhlelo zokusebenza ezimbonini ezahlukahlukene. Embonini yokudayisa, ingasetshenziselwa ukuthengisa, ukuphathwa kwempahla kanye nokuskena ilebula lentengo. Ekuphatheni nasekugcineni impahla, ingakwazi ukuskena ngokushesha futhi ilandelele izimpahla. Ekunakekelweni kwezempilo, imitapo yolwazi nezinye izindawo, ingasetshenziswa ukulandelela nokuphatha izinto. Ngaphezu kwalokho,Izikena zekhodi yebha ye-CCD ye-1Didlala indima ebalulekile ekukhiqizeni, kwezokuthutha, ekuphepheni kokudla nakwezinye izimboni. Ithuthukisa ukusebenza kahle komsebenzi, inciphisa izinga lamaphutha okwenziwa ngesandla futhi ithuthukise ukusebenza komsebenzi kukonke.
2.Izici nezinselelo zamakhodi esikrini
2.1. Ikhodi yesikrini wuhlobo olukhethekile lwekhodi ye-QR eboniswa esikrinini sedivayisi kagesi. Ingaskenwa ukuze kufundwe ulwazi lwekhodi ye-QR esikrinini. I-Screen Code inezinhlobonhlobo zezimo zohlelo lokusebenza, okuhlanganisa i-e-payment, i-e-ticketing, ukuqinisekiswa kwe-e-identity nokunye. Isibonelo, inkokhelo yenziwa nguukuskenaikhodi yesikrini kumakhalekhukhwini, noma ukuqinisekiswa kokufakwayo kwenziwa ngokuskena ikhodi yesikrini ku-e-thikithi.
2.2. Izici eziyinhloko zamakhodi esikrini zifaka ukugqama okuphansi, izinkinga zokubonisa nokuhlehlisa, njll.
Ukugqama okuphansi: Njengoba ukuboniswa kwamakhodi e-QR esikrinini kukhawulelwe ukukhanya nokugqama kwesikrini, ngezinye izikhathi ukugqama okumnyama nokumhlophe kwamakhodi e-QR kuphansi, okwenza kube nzima ngamadivaysi okuskena ukuze awathole ngokunembile.
Inkinga yokubonakala: Ukukhanya okukusikrini kuboniswa emuva kudivayisi yokuskena, okwenza kube nzima ngedivayisi yokuskena ukuhlukanisa imingcele nemininingwane yekhodi ye-QR. Lokhu kungase kubangele ukuthi ikhodi yesikrini ingaziwa kahle idivayisi yokuskena.
Inkinga yokuhlehlisa: Phakathi nenqubo yokuskena ikhodi ekusikrini, ukukhanya kuphikiswa izikhathi eziningi idivayisi yokuskena nesikrini, okungase kubangele ukuthi idivayisi ethwebulayo ingakwazi ukufunda ulwazi olukukhodi ye-QR ngokunembile.
2.3. Izikena zebhakhodi ze-CCD zendabuko ze-1D zibhekana nezinselele eziningi lapho ziskena amakhodi asesikrinini.
Inselele yokuqhathanisa okuphansi: Izikena zebhakhodi ze-CCD ezivamile zingase zingakwazi ukufunda amakhodi asesikrinini anomehluko ophansi. Njengoba ukuboniswa kwamakhodi esikrini kukhawulelwe ukukhanya nokugqama kwesikrini, idivayisi ethwebulayo ingase ingakwazi ukuthwebula kahle nokukhipha amakhodi ulwazi kukhodi ye-2D.
Izinselele zokubonisa nokuhlehlisa: Ukukhanya okuvela kumakhodi asesikrinini kuyaboniswa futhi kunqanyuliwe, okwenza kube nzima ngezikena ukufunda ngokunembile amakhodi e-QR. I-CCD yomdabuIzikena zebhakhodi ze-1Dngokuvamile adizayinelwe ukuskena amabhakhodi ephepha futhi angase angakwazi ukubhekana ngokuphumelelayo nezinkinga zokubonisa nokuphindaphinda zamakhodi esikrini.
Ukuze unqobe lezi zinselele, manje sekunamadivayisi aklanyelwe ukuskena amakhodi esikrini, njengeIzikena ze-2Dnoma izikena zekhodi yesikrini ezikhethekile. Lawa madivayisi asebenzisa ubuchwepheshe bokuskena obuthuthuke kakhulu ukuze athwebule kangcono futhi akhiphe amakhodi ulwazi kumakhodi esikrini.
Uma unentshisekelo noma umbuzo ngesikhathi kukhethwa noma kusetshenziswa noma yisiphi isithwebuli sebhakhodi, sicela uchofoze isixhumanisi esingezansi uthumele umbuzo wakho kumeyili yethu esemthethweni.(admin@minj.cn)ngqo!MINJCODE izibophezele ocwaningweni nasekuthuthukisweni kobuchwepheshe besithwebuli sebhakhodi kanye nemishini yokufaka isicelo, inkampani yethu inesipiliyoni seminyaka engu-14 sembonini emikhakheni yobungcweti, futhi iye yaqashelwa kakhulu iningi lamakhasimende!

3.1 Izikena ezithile zebhakhodi ze-CCD ze-1D zinekhono lokuskena amakhodi asesikrinini. Lezi zikena zenzelwe ngokukhethekile ukuhlonza nokuqopha ulwazi lwekhodi ye-2D oluboniswa esikrinini. Bangakwazi ukufunda amakhodi esikrini ngokungafani okuphansi, ukuboniswa kanye nezinkinga zokuhlehlisa ukuze banikeze imiphumela enembile.
3.2 Amazinga omkhiqizo kanye nokucaciswa kokusebenza kubalulekile lapho uskena amakhodi akusikrini. Ngenxa yokuthi amakhodi esikrini anezidingo ezikhethekile zokuskena, izikena kuphela ezinobuchwepheshe obufanele nezici ezingakwazi ukuskena ngempumelelo. Ngakho-ke, lapho uthenga isithwebuli sebhakhodi ye-CCD ye-1D, qiniseka ukuthi sinamandla okuskena ikhodi yesikrini futhi unake amazinga omkhiqizo afanelekile nezinkomba zokusebenza, njengokunemba kokuskena, ukucindezelwa kwesibonisi kanye nokumelana nokuphikiswa.
Esikhathini sedijithali, i-1D CCDisithwebuli sekhodi yebhainenani elibanzi lebhizinisi namathemba. Ingasetshenziswa kwezokudayisa, ezokuthutha, ezokuthutha, amathikithi nezinye izimboni ukuze kuthuthukiswe ukusebenza kahle komsebenzi nokuhlinzeka ngolwazi lomsebenzisi olulula. Ngakho-ke, ukukhetha isikena esilungile sebhakhodi ye-CCD ye-1D kanye nokuqonda amandla aso okuskena amakhodi asesikrinini kuyisinyathelo esibalulekile esiya ekuguqukeni kwedijithali.
Sithemba ukuthi lolu lwazi lusiza wonke amakhasimende ethu ukuthi aqonde izici zezikena zethu, zizwe ukhululekile ukuchofoza kuzoxhumana nabasebenzi bethu bokuthengisafuthi uthole lesisho namuhla.
Uma Usebhizinisini, Ungase Uthande
