Barcode kelmadaha. macluumaad waxtar leh

Maqaalkani waxa uu sharixi doonaa waxa code bar kelmadaha, by taas oo fududayn lagu qoro macluumaadka.

Barcode yeedhay macluumaad encoded akhriyo by qalab gaar ah. Waxaa laga codsadaa in ay xirmo, waxay u muuqataa sida stroke. code bar The encode kartaa warbixin ku saabsan qaar ka mid ah ku soo koobin muhiim ah oo badeecada.

The Eân ugu badan (nidaamka koodh Yurub) iyo American Universal Product Code UPC.

Sidee loo kelmadaha code bar ah? More on hoos.

Dhismaha macluumaadka encoded ka mid ah:

- dalka of code asal ahaan, sida caadiga ah laba ama saddex lambar,

- code saaraha ee - a afar ama shan lambar - waxa ay ku xiran dhererka code dalka;

- dheeraad ah shan lambarada - magaca sheyga, hantida midabka, miisaanka, size, iyo macaamiisha;

- sideed nambar ee ugu danbeyso - gacanta, kaas oo waxaa loo isticmaalaa si loo xaqiijiyo sax ah reading scanner barcode.

Mararka qaarkood waxaa ku Sugan Calaamad on xaq ">", taas oo macnaheedu yahay in la sii daayo alaabta hoos liisanka.

barcode kelmadaha bixisaa macluumaad badan oo muhiim ah oo ku saabsan alaabta.

Si loo xaqiijiyo code ka bar ay run tahay ama aan, ka xisaabaha soo socda waa in la sameeyaa. Isku dar oo dhan lambarada in ku yaalaan on xitaa dhulka. Markaas tarma wadarta keentay by saddex. Save natiijada, waxaan u yeedhi doonaa "X".

tiro dheeraad ah duubnaadaan (laakiin aan lahayn lambarka tixraaca) diyaarin duurka ku cajiib ah, wadarta this lagu daraa tirada "X" ka helay hore. Of lacagta, taas oo soo baxay (aan u «YZ» wac), oo keliya Z. Next, waxaan u qabtaan tallaabo fudud: 10- Z.

Haddii tirada in la helo, la mid ah sida ay dalbatay qoran barcode ah, shayga waa dhab. Haddii aysan u dhigma, ka dibna wax soo saarka la sameeyey oo aan waafaqsanayn sharciga ah.

barcode kelmadaha muujin kartaa macluumaad ku saabsan waddanka alaabta soo saaray, lambarka aqoonsiga ee shirkadda, magaca sheyga.

macluumaad habaynteeda waxaa loo isticmaalaa dunida oo dhan. Sidaas daraaddeed, bal ka fiirso noocyada kala duwan ee sicirada.

Mid ka mid ah barcode ugu fudud waa "2 of 5". Calaamadaha oo muujinaya tiro ka eber ilaa sagaal, in laftiisa ku jira shan khadadka, labo ka mid ah kuwaas oo ballaaran, iyo saddex - cidhiidhi ah.

Nusqaamaha dhexeeya stroke aan qaado wixii xog ah oo caadi ahaan width farqiga u dhigmaa width ee bar cidhiidhi ah. code Tani, marka lagu daro lambar, ka kooban characters "bilaabaan" iyo "joojiyaan". Just saddex stroke loo isticmaalo in ay image, kuwaas oo laba yihiin ballaadhan. Nusqaamaha macluumaadka waxba ma aad dhashid code "2 of 5" taxane ah Discrete, sidaas darteed si fudud loo daabaco, iyo si toos ah la ogaado qaladka kaliya.

Currently, code bar badeecadaha ayaa sidoo kale noqon kartaa multi-midab.

Code "Codabar" waa barcode a semielementnym Discrete. Waxaa ku jira tiro ka eber ilaa sagaal, calaamadaha "-" iyo "+", "/", ":" 4 lambar "bilowdo / joojiyo" iyo calaamad dollar ah ".". bar "Codabar" code on bidix iyo midig waxaa ugu sugan calaamooyin kooban. calaamada u eg afar stroke iyo saddex goobaha.

code Bar "39" waxaa sidaas la odhan jiray sababtoo ah qaab-dhismeedka image ee characters "3 iyo 9" waa ballaadhan halkaas oo saddex walxaad (hal dalool oo laba stroke) sagaal cidhiidhsan - lixda kale. code Tani waa lagu kalsoonaan karo oo ku filan, iyo waxa teedu uu faa'iido. Sidoo kale, isku halaynta of code noocan oo kale ah waa la kordhin karaa by daray qof gacanta ku ah in dabeecadda.

wax soo saarka barcode waa hab lagu diiwaangeliyo macluumaadka.

meel gaar ah ayaa ka mid ah nidaamka bar-sireed kala duwan qaadataa code bar "93". Iyadoo set isku mid ah oo ah lambar macluumaadka sida xeerka "39", waxa ay ku siin karaan image a cufnaanta sare ee characters. Siddeed iyo afartan calaamadaha lagu sawiray ee "93" code. Waxaa ka mid ah Aayaadka "bilowdo / joojiyo" calaamad gacanta afar iyo afartan saddex lambar ee xeerka "39".

Iyada oo awood u leh inay encode a boqol iyo siddeed iyo labaatan, iyo jilayaasha kala duwan ee la xidhiidha magaca code bar ah "128". code The "128" - code a caasiyoobay oo joogto ah. calaamadaha ka mid ah saddex baararka iyo saddex goobaha, iyo dhererka kasta waa kow iyo toban cutub.

Waxaan ka fikiray qaar ka mid ah codes bar in ay yihiin riyaaqay dunida oo dhan.
