1) Kuchuluka kwakugwiritsa ntchito ukadaulo wa Barcode umagwiritsidwa ntchito nthawi zosiyanasiyana, ndipo owerenga ma bar code osiyanasiyana ayenera kusankhidwa. Mwachitsanzo, kuti mupange kasamalidwe ka bar code warehouse, nthawi zambiri pamafunika kuwerengera ma laboratories omwe ali mnyumba yosungiramo katundu. Momwemonso, owerenga ma bar code amafunika kuti azikhala osunthika ndipo amatha kusunga kwakanthawi zambiri zomwe zasungidwa m'malo mongogwiritsa ntchito patsogolo pa kompyuta. Ndi bwino kusankha kunyamula bar code reader. Zoyenera. Mukamagwiritsa ntchito chojambulira barcode pamzere wopanga, nthawi zambiri ndikofunikira kukhazikitsa chowerengera cha barcode pamalo ena okhazikika pamzere wopangira, ndipo magawo omwe amapangidwa ndi oyenera owerenga barcode, monga mtundu wa mfuti ya laser, CCD scanner, ndi zina zambiri. Mu kasamalidwe ka misonkhano ndi kachitidwe ka opezekapo pamabizinesi, wowerengera wamtundu wa khadi kapena mtundu wa slot-barcode angasankhidwe. Munthu amene akuyenera kulowa adzayika satifiketi yosindikizidwa ndi barcode mu kagawo ka owerenga, ndipo owerenga angojambula yekha ndikupereka chizindikiro chopambana. Izi zimathandizira kuti mulembetse nthawi yeniyeni. Zachidziwikire, pazochitika zina zapadera, zida zapadera zowerengera ma bar code zitha kupangidwanso kuti zikwaniritse zosowa.

2) Mtundu wa decoding Mtundu wa decoding ndi chizindikiro china chofunikira posankha owerenga barcode. Pakali pano, mitundu yosiyanasiyana ya owerenga barcode opangidwa ndi makampani osiyanasiyana ndi yosiyana kwambiri. Owerenga ena amatha kuzindikira ma code angapo, ndipo owerenga ena amatha kuzindikira makina opitilira khumi ndi awiri. Mukapanga makina ogwiritsira ntchito bar code, sankhani dongosolo lofananira. Pa nthawi yomweyi, pokonza owerenga bar code pa dongosolo, owerenga amafunika kukhala ndi ntchito yomasulira molondola zizindikiro za dongosolo ili la code. Pazinthu, UPC/EAN code imagwiritsidwa ntchito nthawi zambiri. Choncho, popanga dongosolo loyang'anira malo ogulitsa, posankha owerenga, ayenera kuwerenga UPC / EAN code. Mu positi ndi ma telecommunication, China pakadali pano imagwiritsa ntchito matrix 25 code. Posankha wowerenga, chizindikiro cha dongosolo la code chimatsimikiziridwa.

3) Kuthekera kwa mawonekedwe Pali magawo ambiri ogwiritsira ntchito luso la barcode, ndipo pali mitundu yambiri yamakompyuta. Mukapanga makina ogwiritsira ntchito, chilengedwe cha hardware nthawi zambiri chimatsimikiziridwa poyamba, ndiyeno owerenga barcode oyenera chilengedwe amasankhidwa. Izi zimafuna mawonekedwe a mawonekedwe a owerenga osankhidwa kuti akwaniritse zofunikira zonse za chilengedwe. Pali mawonekedwe awiri modes kwa ambiri barcode owerenga: A. Seri kulankhulana. Njira yolankhuliranayi nthawi zambiri imagwiritsidwa ntchito pakakompyuta yaying'ono komanso yapakatikati, kapena pomwe malo osonkhanitsira deta ali patali ndi kompyuta. Mwachitsanzo, mu kasamalidwe ka ogwira nawo ntchito, makompyuta nthawi zambiri samayikidwa pakhomo ndi potuluka, koma muofesi, kuti amvetse momwe opezekapo alili munthawi yake. B. Kutsanzira kiyibodi ndi njira yolumikizirana yomwe imatumiza uthenga wa barcode womwe wowerenga amasonkhanitsidwa kupita pakompyuta kudzera padoko la kiyibodi pakompyuta, komanso ndi njira yomwe imagwiritsidwa ntchito kwambiri. Pakadali pano, njira za kiyibodi monga XKAT zimagwiritsidwa ntchito kwambiri ku IBM/PC ndi makina ake ogwirizana. Doko la kiyibodi la terminal ya kompyuta lilinso ndi mitundu yosiyanasiyana. Choncho, ngati mwasankha kutsanzira kiyibodi, muyenera kulabadira mtundu wa kompyuta mu dongosolo ntchito, ndi kulabadira ngati owerenga osankhidwa angagwirizane kompyuta.

4) Zofunikira pazigawo monga chiwerengero choyamba chowerengera Chiwerengero choyamba chowerengera ndi chizindikiro chokwanira cha owerenga barcode, omwe amagwirizana ndi kusindikiza kwa zizindikiro za barcode, mapangidwe a osankha ma code ndi machitidwe a photoelectric scanner. M'magawo ena ogwiritsira ntchito, chowerengera cha bar code chamanja chingagwiritsidwe ntchito kuwongolera kusanthula mobwerezabwereza kwa zizindikiro za barcode ndi anthu. Panthawiyi, zofunikira pa chiwerengero choyamba chowerengera ndizovuta kwambiri, ndipo ndi gawo chabe la ntchito yabwino. Pakupanga mafakitale, kudzisungira nokha ndi ntchito zina, kuwerengera koyambirira kumafunikira. Chonyamulira chotengera barcode chimayenda pamzere wopangira zokha kapena lamba wotumizira, ndipo pali mwayi umodzi wokha wosonkhanitsa deta. Ngati chiwerengero choyamba chowerengera sichifika 100%, chodabwitsa cha kutayika kwa deta chidzachitika, zomwe zimabweretsa zotsatira zoopsa. Chifukwa chake, m'magawo ogwiritsira ntchitowa, owerenga ma bar code omwe amawerenga kwambiri koyamba, monga ma scanner a CCD, akuyenera kusankhidwa.

5) Kusankhiratu Posankha chipangizo chodziwira bwino kukula kwa kapamwamba kakang'ono komwe kamawerengedwa, kachulukidwe ka barcode wogwiritsidwa ntchito mumasankha chida chowerengera chomwe chili ndi lingaliro loyenera. Pogwiritsidwa ntchito, ngati chiganizo cha chipangizo chosankhidwa ndichokwera kwambiri, dongosololi lidzakhudzidwa kwambiri ndi smudges ndi de-inking pa mipiringidzo.

6) Mawonekedwe a Scan Properties scanning amatha kugawidwa m'magawo akuya, kusanthula m'lifupi, kuthamanga kwa sikani, kuchuluka kwa kuzindikira nthawi imodzi, kulakwitsa pang'ono, ndi zina zambiri. amaloledwa kuchoka pamwamba pa barcode ndi mtunda wapafupi kwambiri womwe scanner ingayandikire pamwamba pa barcode pansi pa malo owonetsetsa kuwerengera kodalirika, ndiko kuti, ntchito yogwira ntchito ya barcode scanner. Zida zina zojambulira tebulo la barcode sizipereka kuzama kwa index ya m'munda muzowonetsa zaukadaulo, koma perekani mtunda wa sikani, ndiko kuti, mtunda waufupi kwambiri womwe mutu wojambulira umaloledwa kuchoka pamtunda wa barcode. Kukula kwa scan kumatanthawuza kutalika kwa chidziwitso cha barcode chomwe chingawerengedwe ndi mtengo wojambulira pamtunda womwe wawunika. Kuthamanga kwa sikani kumatanthawuza kuchulukira kwa nyali yowunikira panjira yojambulira. Mlingo wozindikirika kamodzi umayimira chiyerekezo cha ma tag omwe amawerengedwa ndi munthu yemwe wajambulidwa koyamba ndi kuchuluka kwa ma tag ojambulidwa. Mlozera woyeserera wa nthawi imodzi wozindikirika umagwira ntchito panjira yozindikiritsa cholembera chonyamula pamanja. Ngati ntchito anapeza chizindikiro akubwerezedwa. Mlingo wolakwika pang'ono ndi wofanana ndi chiŵerengero cha chiwerengero cha zizindikiro zabodza. Kwa kachitidwe ka bar code, kulakwitsa pang'ono ndi vuto lalikulu kuposa kutsika kozindikirika kamodzi.

7) Chizindikiro cha barcode kutalika kwa chizindikiro cha bar-tri-symbol ndi chinthu chomwe chiyenera kuganiziridwa posankha owerenga. Chifukwa cha ukadaulo wopanga, makina ena ojambulira zithunzi amafotokozera kukula kwake kwakukulu, monga makina ojambulira a CCD ndi ma scanner osuntha. M'makina ena a mapulogalamu, kutalika kwa chizindikiro cha barcode kumasinthidwa mwachisawawa, monga nambala yolozera ya bukhu, kutalika kwa chizindikiro cha barcode pa phukusi lazinthu, ndi zina zotero. M'mapulogalamu amitundu yosiyanasiyana, chikoka cha chizindikiro cha barcode kutalika chiyenera zidziwike posankha wowerenga. 8) Mtengo wa owerenga Chifukwa cha ntchito zosiyanasiyana za owerenga, mitengo imakhalanso yosagwirizana. Choncho, posankha owerenga, tcherani khutu ku chiŵerengero cha ntchito-mtengo wa malonda, ndipo ayenera kukwaniritsa zofunikira za dongosolo la ntchito ndipo mtengo uyenera kukhala wotsika monga mfundo yosankhidwa. 9) Ntchito zapadera Ndikofunikira kuti mulowe kuchokera kuzipata zingapo ndikugwirizanitsa owerenga angapo ku kompyuta imodzi, kotero kuti owerenga pakhomo lililonse akhoza kusonkhanitsa zambiri ndikuzitumiza ku kompyuta yomweyo. Chifukwa chake, owerenga akuyenera kukhala ndi ntchito zapaintaneti kuti awonetsetse kuti makompyuta amatha kulandira zidziwitso molondola komanso kuthana ndi nthawi yake. Pamene makina ogwiritsira ntchito ali ndi zofunikira zapadera kwa owerenga barcode, kusankha kwapadera kuyenera kupangidwa.
