Uma sikhuluma ngomgomo wemojula yesithwebuli, kungenzeka ukuthi asijwayelekile. Ukulawula okuzenzakalelayo noma ukulandelela imikhiqizo emigqeni yokukhiqiza, noma ukuhlelwa kwezimpahla okuzenzakalelayo ohlelweni lokudlulisa oludumile ku-inthanethi, konke kudinga ukuncika kubhakhodi yemojula yesithwebuli ukuze kuhlonzwe imikhiqizo. Nakhu ukwethula isimiso semojula yesithwebuli kanye nokusetshenziswa kwayo ekufundweni kwekhawunta.
Umgomo wemojuli yesithwebuli sebhakhodi
Imojuli yesithwebuli, ngokuvamile ngokuhlanganiswa kwemojula yokuqaphela nekhamera, ingaqedela ukuhlonza okuzenzakalelayo kwebhakhodi ezindaweni ezihlukahlukene eziyinkimbinkimbi ngokusebenzisana nezinzwa kanye nobuchwepheshe obuhlukahlukene bokuhlaziya okuhlakaniphile okuthuthukile, futhi idlulisele idatha noma amasignali kukhompuyutha noma i-PLC. Namuhla, ngokuthuthukiswa kobuchwepheshe kanye nesidingo seminyaka yolwazi, imojula yesithwebuli ingakwazi ukufunda ikhodi engu-2d. Ikhodi ye-2d ibonakala ngobuningi be-lattice obuphezulu, obufaneleka ngokukhethekile ukulawulwa okuzenzakalelayo nokuphathwa kokulandela umkhondo wemikhiqizo yosayizi omncane.
Ubuchwepheshe besithombe be-CCD be-matrix busetshenziselwa ukuhlanganisa ukukhanya, ukutholwa kwezithombe, ukucutshungulwa kwezithombe, amamojula okukhipha amakhodi nokuxhumana, angakwazi ukubona ngokushesha futhi kalula ibhakhodi engu-1d, ibhakhodi estakiwe engu-2d (njenge-PDF417) kanye nebhakhodi ye-matrix engu-2d (njenge-Datamatrix nekhodi ye-QR ) ngendlela eyindilinga. Njengoba isakhiwo sihlangene kakhulu futhi umbono nokujula kwensimu kubanzi, kulula ukuhlanganisa emgqeni wokukhiqiza othomathikhi noma imishini ezenzakalelayo.
Ikhawuntaukufundwa kwesithwebuli sebhakhodi
Emaketangeni ezitolo, ezitolo ezidayisa ukudla, ezitolo zezincwadi noma emakhemisi, ophatha imali ngokuvamile uthatha izimpahla aziyise ekhawuntani ukuze kuskenwe ibhakhodi. Iskena sebhakhodi yedeskithophu sihlangene ngesakhiwo, ngokuvamile sibekwe phezu kwekhawunta ye-cashier futhi sixhunywe ohlelweni lwe-POS. Yakha imigqa yokuskena yenethiwekhi eminingi enqamula ngewindi elikhulu lokuskena, ngaleyo ndlela ibone ukuskena kwebhakhodi ye-omnidirectional. Abasebenzisi abadingi ukulungisa ngokucophelela isiqondiso sebhakhodi, kodwa futhi bangafunda ngokushesha futhi kalula ibhakhodi yempahla, basheshise inqubo yokubala.
Imojuli yesithwebuli sebhakhodi ayisetshenziswa kakhulu embonini yokukhiqiza kuphela. Iphinde idlale indima ebonakalayo ekuthengiseni kabusha.
