ʻIke ʻia ʻo Barcode Scanning Module ʻo Barcode Scanning Module, Barcode Scanning Engine, ma ka ʻōlelo Pelekania (Barcode Scan Engine a i ʻole Barcode Scan Module). He ʻāpana ʻike kumu i hoʻohana nui ʻia ma ke kahua o ka ʻike ʻakomi. ʻO ia kekahi o nā ʻāpana koʻikoʻi no ka hoʻomohala ʻana i ka lua o nā scanner barcode. Loaʻa iā ia nā hana scanning barcode a kūʻokoʻa, a hiki iā ia ke kākau i nā hana noi noi ʻoihana e like me ka mea e pono ai. He liʻiliʻi ka nui a me ka hoʻohui kiʻekiʻe, a hiki ke hoʻokomo maʻalahi i nā kelepona paʻa lima, nā lolouila papa, nā mea paʻi, nā lako laina hui, nā mea lapaʻau, a me nā mea hana ʻē aʻe ma nā ʻano āpau o ke ola. Ma ke kaʻina hana hoʻomohala, ʻo ka ʻoihana barcode scanning module ma nā ʻāina ʻē he ʻano mua, a ʻoi aku ka oʻo o ka ʻenehana. ʻO nā mea nui loa me Honeywell, Motorola, Symbol, etc.

1: Hoʻokaʻawale Hiki ke hoʻokaʻawale ʻia ka module scanning barcode i hoʻokahi-dimensional code module a me ʻelua-dimensional code module e like me ka like o ka nānā ʻana, a hiki ke hoʻokaʻawale ʻia i ka module laser a me ka module kukui ʻulaʻula e like me ke kumu kukui. ʻO ka ʻokoʻa ma waena o ka module laser a me ka module kukui ʻulaʻula ʻO ke kumu o ka module scanning laser ʻo ia ka mea e hoʻopuka ai ka mea laser kūloko i kahi kumu kukui laser, paʻi i kahi pepa hoʻomanaʻo me kahi mea hana mechanical, a laila hilinaʻi i ka mīkini vibration e koli i ke kiko laser. i loko o kahi laina laser a hoʻomālamalama i ka barcode, a laila hoʻokaʻawale iā ia ma o AD. Hōʻailona kikohoʻe.

2: Hoʻohana maʻamau nā modula nānā ʻulaʻula i nā kumu kukui LED light-emitting diode, hilinaʻi i nā mea kiʻi kiʻi CCD, a laila hoʻohuli iā lākou ma o nā hōʻailona photoelectric. ʻO ka hapa nui o nā modules scanning laser e hilinaʻi nei i ka hāʻawi ʻana i ke kāpili e hoʻoponopono ai i ka mīkini mīkini, no laila e maʻalahi pinepine ia i ka pōʻino i ka wā e koli ai, a hāʻule ka ʻāpana pendulum, no laila hiki iā mākou ke ʻike pinepine i ke kumu kukui i nānā ʻia e kekahi mau pū laser. mahope o ka haule ana. , ka hopena i ka hana hou kiʻekiʻe loa. ʻAʻohe ʻano mechanical i ka waena o ka ʻulaʻula scanning module, no laila ʻaʻole hiki ke hoʻohālikelike ʻia ke kūpaʻa hāʻule i ka laser, no laila ʻoi aku ka maikaʻi o ka paʻa, a ʻoi aku ka haʻahaʻa o ka hoʻoponopono ʻana o ka ʻulaʻula scanning module ma mua o ka nānā ʻana i ka laser. module.

3：Mai ke kumu kino o ka laser a me ke kukui ʻulaʻula: ʻO ka Laser e pili ana i ke kukui me ka ikaika hoʻoulu ʻia ka ikehu radiation a me ka parallelism maikaʻi, a i kēia manawa ua hoʻokuʻu ʻia ka hapa nui o ke kukui ʻulaʻula e nā LED. ʻAʻole ʻo ke kukui ʻulaʻula ke ʻano o ka infrared a mākou e ʻōlelo ai. ʻO ka infrared i wehewehe ʻia e ka physics ʻo ia ka hoʻoheheʻe ʻana o nā mea me ka mahana. nā nalu electromagnetic, ʻike ʻole ʻia. Hoʻokomo ʻia ka infrared i nā kukui āpau me nā lōʻihi hawewe ʻoi aku ka nui ma mua o ke kukui ʻulaʻula, aʻo ka laser e pili ana i ka mālamalama me kekahi lōʻihi nalu. ʻAʻole pili pono nā mea ʻelua a ʻaʻole pili i ka māla hoʻokahi. ʻO Laser ka radiation i hana ʻia e ka hoʻonui ʻana i ka hoʻokuʻu ʻia. ʻO ka infrared ka ʻāpana o ka spectrum me ka haʻahaʻa haʻahaʻa a me ka lōʻihi o ka nalu nui ʻaʻole hiki ke ʻike ʻia e ka maka ʻōlohelohe. ʻO ka lōʻihi o ka nalu mai 0.76 a 400 microns. ʻOi aku ka hewa o ke komo ʻana a me ka anti-interference o ke kukui ma mua o ka laser, no laila ʻoi aku ka maikaʻi o ka laser waho ma mua o ke kukui ʻulaʻula ma lalo o ke kukui ikaika.
