Ua kapa ʻia nā ʻano ʻano ʻokoʻa he mea heluhelu barcode, barcode scanner, barcode scanner, barcode scanner a me barcode scanner e like me nā inoa maʻamau. .Hoʻohana mau ʻia i loko o nā hale waihona puke, nā halemai, nā hale kūʻai puke a me nā hale kūʻai nui, ma ke ʻano he kumu hoʻokomo no ka hoʻopaʻa inoa wikiwiki ʻana a i ʻole ka hoʻoponopono ʻana, hiki iā ia ke heluhelu pololei i ka ʻike barcode ma ka ʻeke waho o nā waiwai a i ʻole nā ​​mea i paʻi ʻia, a hoʻokomo i loko o ka ʻōnaehana pūnaewele.

1. ʻO ka barcode scanner kahi mea i hoʻohana ʻia e heluhelu i ka ʻike i loko o ka barcode. ʻO ke ʻano o ka scanner barcode ka mea maʻamau i kēia mau ʻāpana: kumu kukui, mea hoʻokipa, nā ʻāpana hoʻololi photoelectric, decoding circuit, interface kamepiula.

2. ʻO ke kumu hana maʻamau o ka scanner barcode: ʻO ke kukui i hoʻokuʻu ʻia e ke kumu kukui e hoʻomālamalama ʻia ma ka hōʻailona barcode ma o ka ʻōnaehana optical, a ua kiʻi ʻia ke kukui i ʻike ʻia ma ka photoelectric converter ma o ka ʻōnaehana optical e hana i kahi hōʻailona uila. a hoʻonui ʻia ka hōʻailona e ke kaapuni. Hoʻokumu ʻia kahi volta analog, e like me ka mālamalama i ʻike ʻia ma ka hōʻailona barcode, a laila kānana a hana ʻia e hana i kahi hōʻailona hawewe huinahā e pili ana i ka hōʻailona analog, i unuhi ʻia e ka decoder ma ke ʻano he hōʻailona kikohoʻe hiki ke ʻae pololei ʻia. e ke kamepiula.

3. Hoʻohana pinepine ʻia nā ʻenehana barcode maʻamau i nā ʻenehana ʻekolu: peni māmā, CCD, a me ka laser. Loaʻa iā lākou nā pono ponoʻī a me nā hemahema, ʻaʻole hiki i kahi scanner ke loaʻa nā pono ma nā ʻano āpau.
