1) Chiyero chekushandisa Bar kodhi tekinoroji inoiswa muzviitiko zvakasiyana, uye akasiyana bar kodhi vaverengi vanofanirwa kusarudzwa. Semuenzaniso, kugadzira iyo bar code warehouse manejimendi system, zvinowanzo fanira kuverenga marabhoritari mudura. Saizvozvo, iyo bar kodhi yekuverenga inodiwa kuti itakurika uye inogona kuchengetedza kwenguva pfupi ruzivo rwezvinyorwa pane kungogumira kushandisa pamberi pekombuta. Zviri nani kusarudza inotakurika bar code reader. Inokodzera. Paunenge uchishandisa bhakodhi muunganidzi pamutsetse wekugadzira, zvinowanzoitika kuti uise muverengi webhakodhi mune dzimwe nzvimbo dzakagadziriswa pamutsetse wekugadzira, uye zvikamu zvinogadzirwa zvinonyanya kukodzera vaverengi vebarcode, senge laser gun type, CCD scanner, nezvimwe. Mumusangano manejimendi system uye bhizinesi rekupinda system, kadhi-mhando kana slot-mhando yebhakodhi muverengi anogona kusarudzwa. Munhu anoda kusaina anoisa chitupa chakadhindwa bhakodhi muchikamu chekuverenga, uye muverengi anongotarisa otopa chiratidzo chekubudirira kuverenga. Izvi zvinogonesa chaiyo-nguva otomatiki kutarisa-mukati. Ehe, kune dzimwe nguva dzakakosha, yakakosha bar kodhi yekuverenga zvishandiso inogona zvakare kuvandudzwa kuti isangane nezvinodiwa.

2) Decoding range Iyo decoding renji ndechimwe chiratidzo chakakosha chekusarudza muverengi webhakodhi. Parizvino, iyo decoding yemhando yevaverengi yebhakodhi inogadzirwa nemakambani akasiyana zvakasiyana. Vamwe vaverengi vanogona kuziva akati wandei kodhi masisitimu, uye vamwe vaverengi vanogona kuziva anopfuura gumi nemaviri kodhi masisitimu. Paunenge uchigadzira bar kodhi application system, sarudza inoenderana kodhi system. Panguva imwecheteyo, pakugadzirisa bar code reader yehurongwa, muverengi anodiwa kuti ave nebasa rekunyatsotsanangura zviratidzo zveiyi code system. Mune logistics, UPC/EAN kodhi inowanzoshandiswa. Naizvozvo, kana uchigadzira yekutenga mall manejimendi system, pakusarudza muverengi, inofanirwa kukwanisa kuverenga UPC/EAN kodhi. Mune post uye telecommunication system, China parizvino inoshandisa matrix 25 kodhi. Paunosarudza muverengi, chiratidzo chekodhi yekodhi inovimbiswa.

3) Interface kugona Kune akawanda maapplication minda yebarcode tekinoroji, uye kune akawanda marudzi emakomputa. Paunenge uchigadzira sisitimu yekushandisa, iyo hardware system nharaunda inowanzotemwa kutanga, uyezve barcode kuverenga inokodzera nharaunda inosarudzwa. Izvi zvinoda iyo interface mode yemuverengi akasarudzwa kuti asangane nezvinodiwa zvenharaunda. Pane maviri interface modes kune general barcode vaverengi: A. Serial kutaurirana. Iyi nzira yekukurukurirana inowanzo shandiswa kana diki uye yepakati kombiyuta system inoshandiswa, kana kana nzvimbo yekuunganidza data inogara kure kure kubva pakombuta. Semuenzaniso, mubhizinesi rekupinda manejimendi system, komputa kazhinji haiiswe pamusuwo nekubuda, asi muhofisi, kuitira kuti ubate mamiriro ekupinda nenguva. B. Kiyibhodhi emulation inzira yekubatanidza iyo inotumira ruzivo rwebhakodhi rwakaunganidzwa nemuverengi kune komputa kuburikidza ne keyboard port yekombuta, uye zvakare inzira inowanzoshandiswa. Parizvino, nzira dzekhibhodi dzakadai seXKAT dzinowanzo shandiswa muIBM/PC uye nemichina yayo inoenderana. Iyo keyboard port yekombuta terminal inewo mafomu akasiyana. Naizvozvo, kana ukasarudza kutevedzera kiibhodhi, iwe unofanirwa kuterera kune rudzi rwekombuta muhurongwa hwekushandisa, uye teerera kuti muverengi akasarudzwa anogona kuenderana nekombuta.

4) Zvinodiwa zvema parameters akadai seyekutanga kuverenga chiyero Chiyero chekutanga chekuverenga chiratidzo chakazara chevaverengi vebhakodhi, iyo ine hukama nemhando yekudhinda yezviratidzo zvebhakodhi, dhizaini yevanosarudza makodhi uye kushanda kwemafotoelectric scanners. Mune mamwe minda yekushandisa, inobatwa neruoko bar kodhi inoverenga inogona kushandiswa kudzora kudzokororwa kudzokororwa kwezviratidzo zvebarcode nevanhu. Panguva ino, zvinodiwa zvekutanga kuverenga zvakanyanya zvakanyanya, uye inongova chiyero chekushanda kwebasa. Mukugadzirwa kwemaindasitiri, kuzvichengetera wega uye mamwe maapplication, mwero wepamusoro wekutanga kuverenga unodiwa. Iyo barcode inoenderana mutakuri inofamba pane otomatiki yekugadzira mutsara kana bhandi rekutakura, uye pane mukana mumwechete wekuunganidza data. Kana nhamba yekutanga yekuverenga isingasviki 100%, chiitiko chekurasikirwa kwedata chichaitika, zvichiguma nemigumisiro yakakomba. Naizvozvo, mundima idzi dzekushandisa, bhaa kodhi yekuverenga ine yepamusoro yekutanga kuverenga, seCCD scanners, inofanirwa kusarudzwa.

5) Resolution Paunosarudza mudziyo wekuona kwakaringana hupamhi hweiyo yakamanikana bhara yakaverengerwa mukati, iyo barcode density inoshandiswa muchishandiso inosarudza chishandiso chekuverenga chine chigadziriso chakakodzera. Mukushandiswa, kana kugadziriswa kwechigadzirwa chakasarudzwa chakanyanya kukwirira, iyo system ichave yakanyanya kukanganiswa ne smudges uye de-inking pamabhawa.

6) Scan Properties Scanning hunhu hunogona kupatsanurwa kuita kudzika kwemunda, hupamhi hwekuvheneka, kumhanya kwekuongorora, chiyero chekuziva nguva imwe chete, chiyero chekukanganisa, nezvimwe. inobvumirwa kusiya nzvimbo yebhakodhi uye nzvimbo yepedyo yepamusoro iyo scanner inogona kusvika kune barcode pamusoro pechikonzero chekuve nechokwadi chekuverenga kwakavimbika, ndiko kuti, kushanda kunoshanda kwebarcode scanner. Mimwe barcode tafura yekuongorora maturusi haapi kudzika kwekutarisa kwemunda index mune tekinoroji zviratidzo, asi ipa iyo yekutarisisa chinhambwe, ndiko kuti, chinhambwe chipfupi icho musoro wekuongorora unotenderwa kusiya iyo barcode pamusoro. Scan wide inoreva kureba kweruzivo rwebhakodhi iyo inogona kuverengerwa nebeam yekuvheneka pane imwe nzvimbo yekutarisisa. Kumhanya kwe scanning kunoreva kuwanda kwemwenje we scanning panjanji. Chiyero chekuzivikanwa kwenguva imwe chete chinomiririra chiyero chenhamba yemategi akaverengwa nemunhu akaongororwa kekutanga kusvika kuhuwandu hwema tag akaongororwa. Indekisi yekuyedza yenguva imwe yekuzivikanwa mwero inongoshanda kune inobatwa neruoko mwenje peni yekuongorora nzira yekuziva. Kana kushandisa yakawanikwa chiratidzo inodzokororwa. Iyo bit error rate yakaenzana nereshiyo yehuwandu hwehuwandu hwekuzivikanwa kwenhema. Kune iyo bar code system, iyo bit kukanganisa chiyero idambudziko rakakura kupfuura yakaderera-imwe nguva yekuzivikanwa mwero.

7) Kureba kwechiratidzo chebhakodhi Bhar-tri-symbol kureba chinhu chinofanira kutariswa pakusarudza muverengi. Nekuda kwesimba rekugadzira tekinoroji, mamwe mafotoelectric scanner anotsanangura saizi yakakura yekuongorora, seCCD scanners uye kufambisa danda scanner. Mune mamwe masisitimu ekushandisa, kureba kwechiratidzo chebhakodhi kunosandurwa zvisina tsarukano, senhamba yebhuku, kureba kwechiratidzo chebhakodhi papakiti yechigadzirwa, nezvimwewo. Mumaapplications eurefu hwakasiyana-siyana, kurudziro yechiratidzo chebhakodhi inofanira kucherechedzwa pakusarudza muverengi. 8) Mutengo wemuverengi Pamusana pemabasa akasiyana-siyana evaverengi, mitengo yacho hainawo. Nokudaro, pakusarudza vaverengi, teerera kune chiyero chekushanda-mutengo wezvigadzirwa, uye inofanira kusangana nezvinodiwa zvehurongwa hwekushandisa uye mutengo unofanira kunge wakaderera seyo sarudzo yekusarudza. 9) Mabasa akakosha Izvo zvinodikanwa kupinda kubva kune akati wandei masuo uye batanidza vaverengi vakati wandei kune imwe komputa, kuitira kuti vaverengi pamusuwo wega wega vatore ruzivo uye vatumire kune imwe komputa. Naizvozvo, vaverengi vanosungirwa kuve nemabasa etiweki kuona kuti komputa inogona kugashira ruzivo nemazvo uye kubata nayo nenguva. Kana iyo application system iine zvakakosha zvinodiwa kune barcode kuverenga, yakakosha sarudzo inofanirwa kuitwa.
