Pali magulu awiri onse a barcode: onedimensional (1D kapena linear) ndi two dimensional (2D). Amagwiritsidwa ntchito m'mitundu yosiyanasiyana, ndipo nthawi zina amafufuzidwa pogwiritsa ntchito mitundu yosiyanasiyana yaukadaulo. Thekusiyana pakati pa 1D ndi 2D barcode scanning imadalira masanjidwe ndikuchuluka kwa deta yomwe ingasungidwe mu iliyonse, koma zonse zingagwiritsidwe ntchitomogwira ntchito zosiyanasiyana zodziwikiratu.
Kusanthula kwa Barcode kwa 1D:
Linear kapena1D barcode, monga khodi ya UPC yomwe imapezeka pa ogulakatundu, gwiritsani ntchito mizere yosiyana-siyana ndi mipata kuti muyike deta -zomwe anthu ambiri amaganiza akamva "barcode". Linearma barcode amakhala ndi zilembo khumi ndi ziwiri zokha, ndipo nthawi zambiri amakhala ndi thupimotalikirapo ngati zambiri zikuwonjezedwa. Pachifukwa ichi, ogwiritsa ntchito amachepetsa awoma barcode mpaka zilembo 8-15.
Makanema a barcode amawerenga ma barcode a 1D mopingasa.1D laser barcodemakina ojambulirandi masikana omwe amagwiritsidwa ntchito kwambiri, ndipo nthawi zambiri amabwera mu a"mfuti" chitsanzo. Ma scanner awa safunikira kulumikizana mwachindunji ndi barcode ya 1D kuti agwire bwino ntchito, koma nthawi zambiri amayenera kukhala mkati mwa 4.mpaka mainchesi 24 kuti muwone.
Ma barcode a 1D amadalira kulumikizana kwa database kuti akhale watanthauzo. Ngati mungayang'ane nambala ya UPC, mwachitsanzo, otchulidwa mu barcode amayenera kuterozimagwirizana ndi chinthu chomwe chili mu database yamitengo kuti chikhale chothandiza. Makina awa a barcodendizofunikira kwa ogulitsa akuluakulu, ndipo zingathandize kuonjezera kulondola kwazinthundi kusunga nthawi.
Kusanthula kwa Barcode kwa 2D:
Ma barcode a 2D, monga Data Matrix, QR Code kapena PDF417, amagwiritsa ntchito mabwalo, mahexagoni, madontho, ndi mawonekedwe ena kuti asungire deta. Chifukwa cha iwoKapangidwe, ma barcode a 2D amatha kukhala ndi data yochulukirapo kuposa ma code a 1D (mpaka 2000zilembo), pomwe zikuwonekabe zazing'ono. Deta imasungidwakutengera kachitidwe koyima ndi kopingasa kwapatani,motero amawerengedwa mbali ziwiri.
Chojambulira barcode cha 2D sichimangoyika zidziwitso za zilembo za alphanumeric.Zizindikirozi zimathanso kukhala ndi zithunzi, ma adilesi awebusayiti, mawu, ndi zinamitundu ya data binary. Izi zikutanthauza kuti mutha kugwiritsa ntchito chidziwitsochokaya mwalumikizidwa ku database kapena ayi. Kuchuluka kwazambiri zitha kuyenda ndi chinthu cholembedwa ndi a2D barcode scanner.
Makanema a barcode a 2D amagwiritsidwa ntchito kuwerenga ma barcode a 2D, ngakhalema barcode ena a 2D, monga ma QR odziwika bwino, amatha kuwerengedwandi mapulogalamu ena a smartphone. Makanema a barcode a 2D amatha kuwerenga kuchokera ku 3mapazi kutali ndipo akupezeka mu kalembedwe wamba "mfuti", komanso opanda zingwe, countertop, ndi masitayilo okwera. Ena2D bar code scannernawonsoyogwirizana ndi ma barcode a 1D, zomwe zimapatsa wogwiritsa ntchito kusinthasintha momwe amachitiraamagwiritsidwa ntchito.
Mapulogalamu a 1D ndi 2D Barcode Technology:
Ma barcode a 1D amatha kufufuzidwa ndi makina amtundu wa laser, kapena kugwiritsa ntchitomakina ojambula zithunzi opangidwa ndi kamera.2D barcode, kumbali ina, imatha kuwerengedwa pogwiritsa ntchito zithunzi.
Kuphatikiza pa kukhala ndi zambiri, ma barcode a 2D amatha kukhala ochepa kwambiri,zomwe zimapangitsa kuti zikhale zothandiza polemba zinthu zomwe zikanakhalaposizothandiza pa zilembo za barcode za 1D. Ndi laser etching ndi matekinoloje ena okhazikika, ma barcode a 2D akhala akugwiritsidwa ntchito kutsata chilichonsekuchokera ku matabwa amagetsi osindikizidwa osakhwima kupita ku zida zopangira opaleshoni.
Ma barcode a 1D, kumbali ina, ali oyenerera kuzindikira zinthu zomwe zingagwirizane ndi zina zomwe zimasintha pafupipafupi. Kupitilizani ndi chitsanzo cha UPC, chinthu chomwe UPC imadziwika kuti sichidzaterokusintha, ngakhale mtengo wa chinthucho umakonda; Ndicho chifukwa chake kulumikiza deta yosasunthika (chiwerengero cha chinthu) ku data yosunthika (malo osungirako mitengo) ndi njira yabwino kuposa encoding zamtengo wapatali mu barcode yokha.
Ma barcode a 2D akhala akugwiritsidwa ntchito mochulukirachulukira mumayendedwe ogulitsa ndikupanga mapulogalamu monga mtengo wa makina ojambula zithunzi watsika. Wolembaposinthira ku ma khodi a 2D, makampani amatha kuyika zambiri zamalondapamene kumapangitsa kuti zikhale zosavuta kusanthula zinthu pamene zikuyenda pamizere ya msonkhano kapenaconveyors - ndipo zitha kuchitika popanda kuda nkhawa ndi scannerkulinganiza.
Izi ndizowona makamaka mu zamagetsi, zamankhwala, ndi zamankhwalamafakitale opanga zida komwe makampani adapatsidwa ntchito yoperekakuchuluka kwazinthu zotsatiridwa ndi zinthu zina zazing'ono kwambiri. Mwachitsanzo, malamulo a USFDA a UDI amafuna zidutswa zingapo zakupanga zambiri kuti ziphatikizidwe pamitundu ina yamankhwalazipangizo. Zomwezo zitha kusungidwa mosavuta pama barcode ang'onoang'ono a 2D.
Ngakhale pali kusiyana pakati1D ndi 2D barcode scanning, onsemitundu ndi njira zothandiza, zotsika mtengo zolembera ma encoding ndi kutsatira zinthu.Mtundu wa barcode (kapena kuphatikiza kwa barcode) zomwe mungasankhe zimadalirapazofunikira zenizeni za ntchito yanu, kuphatikiza mtundu ndikuchuluka kwa deta yomwe muyenera kuyika, kukula kwa katundu/chinthucho, ndi momwendi komwe code idzasinthidwe.
Ngati muli ndi chidwi kapena funso posankha kapena kugwiritsa ntchito scanner ya bar code, landiraniLumikizanani nafe! MINJCODEakudzipereka ku kafukufuku ndi chitukuko cha bar codescannerzipangizo zamakono ndi ntchito,kampani yathu ili ndi zaka 14 zamakampani odziwa ntchito, ndipo yadziwika kwambiri ndi makasitomala ambiri!
