Sesiphi iskena esikulungeleyo?
Fumana ukuba zeziphi izikena zebarcode ezifanelekileyo kushishino lwakho oluthile, okusingqongileyo kunye neemfuno. Fumana amandla okoyisa wonke umqobo ngeeskena ezenzelwe ukuskena nantoni na, naphi na - nokuba yintoni na.
1, uMpu oBomvu wokuSkena kunye neSkena seLaser
Umpu wokuskena obomvu wamkela umthombo wokukhanya we-LED, oxhomekeke kwi-CCD okanye kwi-CMOS ye-photosensitive elements emva koko uguqule imiqondiso yombane. I-laser scanning gun ikhanyisa indawo yelaser ngesixhobo selaser yangaphakathi, kwaye indawo yelaser ijikwa ibe ngumqa wokukhanya kwelaser kwikhowudi yebha ngokujingisela kwemoto yokungcangcazela, ethi ke igqitywe ibe ngumqondiso wedijithali yiAD. Ngenxa yokuba i-laser ixhomekeke kwi-motor vibration ukwenza umgca welaser, yonakaliswa ngokulula kwinkqubo yokusetyenziswa, kwaye ukusebenza kwayo kokuchasana nokuwa ihlala ingekho kulunga njengaleyo yokukhanya okubomvu, kwaye isantya sokubonwa kwayo asikhawulezi kangako. njengaleyo yesibane esibomvu.
2,Umahluko phakathi kwe-1D Scanner kunye ne-2D Scanner
Iskena sebhakhowudi ye-1D sinokuskena kuphela iikhowudi zebhakhowudi ze-1D, kodwa hayi iikhowudi zebhakhowudi ze-2D; Iskena sebhakhowudi ye-2d sinokuskena zombini iikhowudi zebhakhowudi ezinomgangatho omnye kunye nezimbini-dimensional. Umpu wokuskena one-dimensional-dimensional ubiza kakhulu kunompu wokuskena onedimensional enye. Kwezinye iimeko ezikhethekileyo, ayizizo zonke iimipu zokuskena ezinamacala amabini ezifanelekileyo, njengokuskena ikhowudi enamacala amabini kwiscreen sefowuni ephathwayo okanye ekrolwe kwintsimbi.
Abafundi bebhakhowudi bayiplagi kwaye badlale ngokusebenza kwescan ekhokelayo kwishishini, ukwenza neyona barcode kunzima ukuyifunda ibonakale ilungile. Nokuba zithini na iimfuno zeshishini lakho, sineskena esisincedayo.
