E ʻike i ka barcode scanner kūpono no kāu ʻoihana kikoʻī, kaiapuni a me nā koi.Loaʻa i ka hiki ke lanakila i kēlā me kēia pilikia me nā scanners i hoʻolālā ʻia e nānā i kekahi mea, ma nā wahi āpau - ʻaʻohe mea.

1, ʻO ka pū ʻulaʻula a me ka ʻimi ʻana i ka laser

Hoʻohana ʻia ka pū kukui ʻulaʻula i ke kumu kukui LED, e hilinaʻi ana i nā mea kiʻi kiʻi CCD a i ʻole CMOS a laila hoʻololi i nā hōʻailona photoelectric.Hoʻomālamalama ka pū ʻana i ka laser i kahi wahi laser e ka mea laser kūloko, a ua hoʻohuli ʻia ka wahi laser i ke kukui laser ma ke code bar ma ke kowali o ka moto vibration, a laila hoʻololi ʻia i kahi hōʻailona kikohoʻe e AD.Ma muli o ka hilinaʻi o ka laser i ka mīkini vibration e hana i kahi laina laser, ʻoi aku ka maʻalahi o ka pōʻino i ke kaʻina o ka hoʻohana ʻana, a ʻo kāna hana anti-fall pinepine ʻaʻole maikaʻi e like me ke kukui ʻulaʻula, a ʻaʻole wikiwiki ka wikiwiki o ka ʻike. e like me ke kukui ʻulaʻula.

2, ʻokoʻa ma waena o 1D Scanner a me 2D Scanner

Hiki i ka 1D barcode scanner ke nānā wale i nā barcode 1D, akā ʻaʻole nā ​​barcode 2D;Hiki i ka 2d barcode scanner ke nānā i nā pahu helu hoʻokahi a me ʻelua.ʻOi aku ke kumu kūʻai ma mua o ka pū scan kiʻi ʻelua-dimensional.I kekahi mau hanana kūikawā, ʻaʻole kūpono nā pū kiʻi ʻelua ʻāpana, e like me ka nānā ʻana i ke code ʻelua-dimensional ma ka pale o ke kelepona paʻalima a i ʻole ke kahakaha ʻia ma ka metala.

Hoʻopili a pāʻani ka poʻe heluhelu barcode me ka hana scan alakaʻi i ka ʻoihana, e ʻoi aku ka maikaʻi o nā barcode paʻakikī loa.ʻAʻohe mea e pono ai kāu ʻoihana, loaʻa iā mākou kahi scanner e kōkua mai.
