I nā makahiki i hala iho nei, ua ʻike nā hale kūʻai nui o ka home, nā hale kūʻai kaulahao a me nā ʻoihana ʻoihana ʻē aʻe i nā pono nui o ka ʻoihanaPūnaehana POSi ka hoʻokele ʻoihana pāʻoihana, a ua kūkulu i ka ʻōnaehana pūnaewele POS pāʻoihana.Hoʻokomo ʻia ke kumu hoʻolālā a me ka hoʻonohonoho ʻana o ka ʻōnaehana pūnaewele i nā kikoʻī i nā nūpepa ʻoihana like ʻole.Kūkākūkā nui kēia pepa i ke koho ʻana i kekahi o nā barcode scanners ma ke ʻano he ʻāpana loaʻa ʻikepili mua o ka ʻōnaehana POS kalepa.
ʻEkolu mau mea hoʻopaʻa helu pāʻoihana maʻamau: ʻO ka scanner barcode CCD, ka scanner barcode laser a me ka scanner barcode angle.
1. ʻO ka scanner barcode CCDhoʻohana i ke kumu o ka photoelectric coupling (CCD) e kiʻi i ke ʻano paʻi barcode, a laila hoʻokaʻawale ia.ʻO kāna mau mea maikaʻi: ʻaʻohe shaft, motor, ola lawelawe lōʻihi.He makaʻu ke kumukūʻai.
Ke koho ʻana i hoʻokahi scanner CCD, ʻelua mau ʻāpana koʻikoʻi: Ka hohonu o ke kahua:
No ka mea, ua like ka CCD kiʻi kumu me ke kāmela, inā makemake ʻoe e hoʻonui i ka hohonu o ke kahua, ka lens hoʻonui e pili ana, i nui loa ka nui o ka CCD, hiki ʻole ke hana.Pono e heluhelu ʻia kahi CCD maikaʻi me ka ʻole o ka hoʻopili ʻana i ke code bar, me ka leo haʻahaʻa a me ka hana ʻoluʻolu.
Hoʻoholo: Inā makemake ʻoe e hoʻomaikaʻi i ka hoʻonā ʻana o ka CCD, pono ʻoe e hoʻonui i ka ʻāpana ʻāpana o ka mea photosensitive ma ke kiʻi.ʻO ka CCD haʻahaʻa haʻahaʻa he ʻelima mau pika, heluhelu ʻo EAN, UPC a me nā code pāʻoihana ʻē aʻe ua lawa, no ka mea paʻakikī ka ʻike code ʻē aʻe.ʻOi aku ka CCD waena ma mua o 1024 pixels, ʻo kekahi a hiki i 2048pixe1, hiki ke hoʻokaʻawale i ka ʻāpana haiki o 0.1mm bar code.
2. Kamīkini paʻi helu pahu laserʻO ia ka laina laina hoʻokahi e hoʻohana ana i ʻelua paipu laser ma ke ʻano he kumu māmā.Loaʻa iā ia ʻelua ʻano: rotary mirror a me vibrato mirror
Ka mea e hoʻohana ai i ka motika kiʻekiʻe e hoʻokele i kahi hui prism e hoʻololi, i lilo ka laser kiko hoʻokahi i hoʻokuʻu ʻia e nā paipu ʻelua i laina.Hoʻopili ʻia kēia laina laser i ke code bar ponoʻī.Hoʻopili ka ʻeleʻele ʻeleʻele i ka hapa nui o ka laser, a ʻike ke keʻokeʻo i ka hapa nui o ka laser.I ka manawa like, ʻike ʻia ka mālamalama i ʻike ʻia ma o ka lens optical i ka 'engine', a ua kālele ʻia ma kahi photoelectric ʻekolu-tube.Nānā i loko o ka manawa domain hōʻike i ka photoelectric ekolu-tube haʻahaʻa pae ma ka bar code ʻeleʻele kāʻei, a kiʻekiʻe ma luna o ke keʻokeʻo kāʻei.Ma hope o kekahi mau hoʻonui ʻana, ua hana ʻia ka nalu ʻāʻī, a ua pili ka nalu ʻāʻī i ke code bar scanned.Hoʻouna ʻia ka nalu i loaʻa i ka decoder ma o ka laina ʻikepili.ʻO ka 'Decoder' kahi microcomputer chip hoʻokahi.Aia ma muli o ka interrupt and single chip counter e hoʻopaʻa i ka manawa lele o ka nalu.Hoʻokaʻawale ʻia ka ʻāpana i hōʻiliʻili ʻia i ka scan hou a i ʻole ka nānā hope.Aia ia i ka ratio manawa o kēia mau helu helu e hoʻokaʻawale i ke code bar pili.I ka hoʻohana pono ʻana, nui nā ʻano o ka bar code, a me nā wrinkles hōʻaiʻē maʻamau e like me ka bubble surface, no laila pono ka ʻāpana decoding i kahi hoʻomanawanui hewa, akā ʻaʻole hiki ke hana i ke code hewa.I kēia manawa, ua māhele ʻia ka decoder i 8 bit a me 32 bit, 8 bit pono ke kumu kūʻai, 32 bit ka wikiwiki.Ka laser bar code market ua cluttered me ka mooolelo, akā, ua hahai pū i ka ccd scanner lepo, kumu kūʻai ua hāʻule pinepine, cottage, akā, aia kekahi mau mana home Manufacturers, nā mea kūʻai mai pono e noonoo akahele i ke ano o ka momoku ahi, koho oi kūpono.
ʻOi aku ka liʻiliʻi o ke kumu kūʻai o ke aniani haʻalulu ma mua o ke aniani ʻōwili, akā ʻaʻole maʻalahi kēia kumu o ka pū laser e hoʻomaikaʻi i ka wikiwiki o ka nānā ʻana, ma ke ʻano he 33 mau manawa i kēlā me kēia kekona.
Ke koho ʻana nā ʻoihana kalepa i kekahi o nā scanner laser, ʻoi aku ka nui o ka nānā ʻana i ka wikiwiki a me ka hoʻonā ʻana, a ʻo ka hohonu o ke kula ʻaʻole ia he kumu nui.No ka mea ke piʻi ka hohonu o ke kahua, e hoʻemi nui ʻia ka hoʻonā.Pono e loaʻa i ka mīkini paʻi lima lima maikaʻi ka wikiwiki scanning kiʻekiʻe a me ka hoʻonā kiʻekiʻe i loko o kahi hohonu paʻa.
3. ʻO ka ʻimi ʻimi ʻokiʻoki he amīkini paʻi pāʻāluae hoʻohuli i ka laser i hoʻopuka ʻia e ka laser diode a i ʻole nā laina scanning lehulehu ma o ka ʻōnaehana optical.ʻO ke kumu nui e hōʻemi i ka hana o ka hoʻoponopono ʻana i ke code bar ke komo ka cashier i ka ʻikepili bar code.Pono kekahi o nā koho e nānā i ka māhele wahi o ka laina scanning:
1. He nui na laina like ma ka aoao hookahi
2. Holo nā laina scan he nui i ka manawa hoʻokahi
3. He kūlike ka mana'o like 'ole o ka wehewehe 'ana o kēlā me kēia kiko i loko o kekahi hakahaka
ʻO ka ʻenekini kihi e like me nā helu ʻekolu ma luna nei kekahi o nā noi o ke koho ʻoihana.
