qalab CCD

Xararad CCD scanner barcode for reading computer isticmaalo tiknoolajiyadda macluumaadka ku saleysan mabda'a isku mid sida in fakisyo ah. scanners CCD waxaa lagu yaqaan laba nooc: xiriirka iyo contactless. Marka la isticmaalayo la xiriir Wadayaasha u baahan tahay in lifaaq scanner ah in qoraalka la code oo riix badhanka ah. khasaare ugu weyn ee scanners oo kale waa in aanay si fiican u shaqeeyaan meelaha aan loo sineyn. The scanners CCD contactless design isticmaali uu Kokes ku-awood sare iyo photosensors xasaasi ah, ogolaanayo in ay ka akhrisan image ka fogaan ah 6 ilaa 30 sentimitir.

scanner Image, ama sida ay u yeedheen photo-scanner isticmaalaa CCD soo diyaariyeen la mid ah sida camera ama fiidiyo. scanner code Tani akhrinaya dhammaan macluumaadka si buuxda oo muhiim ma ahan in ay si gaar ah u bar-on baakada.

qalab laser for reading

Gacanta lagu scanner laser code bar in computer ku haboon oo ay fududahay in la shaqeeyaan. meesha ay shaqada ka gaari karin 20-110 sentimitir, iyo qaar ka mid ah ilaa 10 mitir.

Multibeam scanners laser

Taagan scanner laser multi-qiyaas foomamka goobta shaqada ah, taas oo ka kooban dhowr alwaaxdii saqafka haysay. Waayo, si ay u awoodaan inay akhriyaan macluumaadka, waxa ku filan in ugu yaraan mid ka mid ah hannaanka ee rays gudbay oo dhan istaroog ah. aaladaha noocan oo kale ah waxaa ka mid ah laba nooc: dhisay-in, kaas oo loo xiraa ee counter diiwaanka lacagta caddaanka ah, iyo qiyaas.

Isugeynta scanner multi-dogob waxaa loo qabanqaabiyaa sidoo kale taagan, waxaa inta badan la kala saaro waa in ay ku qaadan kartaa ilaa. Meesha shaqeeyo taas oo ay jirto aqoonsiga codes bar (codes bar), qalabka sida waa la dhimay sida la taagan marka la barbar dhigo.

scanner Bioptic abuuraa laba goobaha shaqada taas oo ay jirto hannaanka ah looxyo waaweyn laser. Waxaa jira lagu daydo ee scanners qalabaysan miisaanka.

Sida loo dhigay scanner ah in uu akhriyo code bar ah?

Ka hor inta aadan isticmaali scanner ah, waxaad u baahan tahay in ay ku xidhmaan aad computer iyo rakibi software lagama maarmaanka ah. Waxaa jira saddex nooc oo ah qalabka si ay u xidhiidhinaya your computer:

1. "waslad keyboard The".

2. Isticmaalka dekedda COM serial (sida waxa loo yaqaan RS232).

3. Isticmaalka USB-dekedaha, kuwaas oo u hoggaansamaa interface RS232 ah.

Ha ka fikiro si aynu saddex siyaabood in ay ku xidhmaan.

Ku xiridda qalabka si akhri code bar ah "in wasladdii keyboard"

dekedda keyboard loo yaqaan PS / 2 iyo waxa loo isticmaalaa la xidhiidha PC sida keyboard iyo mouse. Haddaba, motherboards badan oo ay leeyihiin kaliya hal xira oo casri ah Netbook iyo buugaagta sida, waxa maqan yahay.

In ay ku xidhmaan keyboard in ay aqriyaan qalabka, waa inaad marka hore computer ka dami, ka keyboard saari fur iyo geliso in ay meel scanner ah. Markaas waxaad u baahan tahay in ay ku xidhmaan keyboard si scanner ah. Marka aad xiran, waxaad u tagi kartaa on the scanner oo computer si ay u Roobka xoogga.

Ka dib markii dhowr qalab barcode qalabaysan interface this ah, xeerka la geliyo meesha dulqabo yahay, sida haddii aad ku qortay on keyboard ah. Sidaas darteed, haddii scanner ma akhrisan kartaa code ama ka mid ah amar, waxaad si toos ah u geli karaa code ka keyboard ah.

Kuwa ku hawlan qalabka iskaanka barcode la interface la mid ah, waa in fiiro gaar ah u khariidad ee keyboard marka aqoonsi tirada serial, taas oo uu leeyahay xarfaha. Tusaale ahaan, marka waxaa ka mid ahaa qaabka keyboard Ruush halkii a code / n123215654QWE tixgeliyo LB / t123215654YTsU.

Habka la xidhiidha Tani badbaadiyay a dekedda COM ama USB, kaas oo noqon kara mid waxtar leh marka xidhiidhinaya computer ah tiro ka mid ah qalabka kala duwan, sida printer ah jeegaga, maaliyadeedka qalabka printer, qolfo leh iyo qalab kale oo lagama maarmaan u ah hawlgalka shaqaalaha dukaanka. Sidoo kale scanner barcode la xidhiidha "in wasladdii keyboard" waxaa loo isticmaalaa marka aad isticmaasho software barcode in ay tahay in kaliya qalabka sida shaqeyn karin.

Dejinta qalabka si akhri code bar ku COM-interfaces ah

COM ama Rs-232 dekedda - kuwani waa laba yeero kala duwan hal interface a kaas oo si computer shakhsi, aad ku xidhan karto noocyo kala duwan oo qalab. isku xira Tan waxaa loo qaybiyay sida leydi, kaas oo ka kooban laba saf oo biinanka (5 ka mid ah oo isku xigta, 4 kale). Macluumaadka kala duwan ee qalabka dibadda iyadoo la isticmaalayo habka gudbinta waxaa loo bixiyey sequentially on labada fiilooyin. By silig xogta Rx bixisey in computer ka, iyo TX for calaamadaha gacanta lagu kala qaado in qalabka. Mararka qaarkood shaqaaleeyaan khadadka dheeraad ah RTS iyo CTS hawlgalka saxda ah ee barnaamijyada. Weli waa suurtagal in la helo guddiga nidaam la mid Rs-232 xira, laakiin dhammaan Netbook casriga ah iyo buugaagta, waxa maqan yahay.

Si aad u rakibi scanner ah, waa in marka hore in ay ku xirmaan dekedda COM PC ee, ka dibna nidaamka qalliinka kasta oo waxa ku weydiin doonaa inaad si loo soo dajiyo darawallada loo baahdo. Waxay waxaa laga heli karaa, ama disk ah in la Timaadda qalabka, ama lagala soo bixi internetka. saarayaasha qaar ka mid ah scanners bixiyaan barnaamijyo gaar ah oo aad ku xakamayn kartaa mugga digtoonida dabka, ama si ay u dejiyaan characters gaar ah.

Sidee in ay ku xidhmaan scanner ah, code bar computer la interface USB ah?

Kasta oo computer oo casri ah, netbook ah, buug qalabaysan dekedda USB ah. In Heerka this, xogta waxaa serially wareejiyo via laba fiilooyin, laba silig waxaa loo isticmaalaa codsanaya danab in qalabka, taas oo ku xiran yihiin PC ah.

Faa'iidada ugu weyn ee qalabka inuu wax akhriyo barcode computer waa sarrifka xogta xawaaraha sare oo awood u leh in ay ku xidhmaan computer orodka ah. scanners barcode gacanta lagu Small baabbi'in qadar yar oo ah awood, sidaas waxaa ku shaqeeya dekedda USB ah. Multiplanar akhristaha awood badan oo sidaas daraaddeed siin a awood gaar ah.

sii kordhaya scanner waa in uu ahaadaa mid sahlan, tan iyo nidaamka qalliinka oo casri ah oo dhan aqoonsan qalabka si akhri codes sida keyboard a caadiga ah, si ay shaqada, iyagu ma ay u baahan yihiin darawallada kasta. Marka barcode la marsiiyey, barnaamijka waxaa durayo meesha dulqabo ku yaal.

scanners badan oo sicirada in xirmaan dekedda USB ah, waxaad samayn kartaa shaqeeyo hab ah kuwaas oo waxaa la jaanqaadaan doonaa Rs-232 dekedda. Inta badan waxay u baahan tahay in la tixgeliyo code gaar ah bar la siiyo tilmaamaha iyo rakibi darawalka dekedda dalwaddii. Ka dib markii qalab kala iibsiga ee hab xaasidnimo COM-interface ah, oo ay la isticmaalo waxaa ka mid ah sida caadiga ah scanner hawlgala heerka Rs-232.

aaladaha badan ee schityvaniyasuschestvuet awood u leh inay dhigay jilayaasha in loo gudbin doono ka hor iyo ka dib barcode ah. Sidaas, ka hor inta reading code, dadka isticmaala badan noqon lahaa ku haboon haddii scanner maray mid ka mid ah jilayaasha sida Insert, F1 ama F9. Maadaama laga yaabo in this ee dhimista tirada, keyboard on operator keyboard iyo fududeeyey hawsheeda.

Hubinta isku xirnaanta iyo scanner waxqabadka

Ka dib markii loo xirxiro ee scanner code bar la dhammeeyo, waxaa lagama maarmaan ah si loo hubiyo hawlgal ka mid ah qalabka.

Si loo hubiyo in scanner ku xiran yahay "in keyboard ee waslad" ama USB-xira si sax ah u shaqeeyaan, waxaad u baahan tahay in uu ordo editor qoraal wax sida "buugayga", oo isku day in iskaan xeerka. Haddii jilayaasha muuqan shaashadda, qalabka si sax ah loo qaybiyay.

Haddii qalab aad u akhriyi sicirada ku lifaaqan ee Rs-232 ama ka shaqeeya via USB in hab COM-interface, pre-u baahan in ay maamulaan barnaamijka kasta terminal oo waxay ag qotomiyeen dekedda saxda ah. ka dibna waxaad ka akhrisan kartaa code ka baakada. Marka si fiican loo qaybiyay, shaashadda waa muuqdaan characters akhrin karo.
