Barcode Scanning Module imadziwikanso kuti Barcode Scanning Module, Barcode Scanning Engine, mu Chingerezi (Barcode Scan Engine kapena Barcode Scan Module).Ndi gawo lodziwikiratu lomwe limagwiritsidwa ntchito kwambiri podzizindikiritsa zokha.Ichi ndi chimodzi mwazinthu zofunika kwambiri pakukula kwachiwiri kwa barcode scanner.Ili ndi kusanthula kwa barcode kwathunthu komanso kodziyimira pawokha, ndipo imatha kulemba ntchito zosiyanasiyana zamakampani momwe zingafunikire.Ili ndi kukula kochepa komanso kusakanikirana kwakukulu, ndipo imatha kuikidwa mosavuta m'mafoni a m'manja, makompyuta a piritsi, osindikizira, zipangizo zopangira msonkhano, zipangizo zamankhwala, ndi zipangizo zina m'madera onse a moyo.Mu ndondomeko yachitukuko, ndi barcode kupanga sikani gawo makampani m'mayiko akunja ndi oyambirira, ndipo luso ndi okhwima.Zina zazikulu ndi monga Honeywell, Motorola, Symbol, etc.

1: Gulu la barcode scanning module litha kugawidwa kukhala gawo limodzi la magawo awiri ndi magawo awiri azithunzi malinga ndi kufanana kwa kupanga sikani, ndipo lingagawidwe kukhala gawo la laser ndi gawo lowala lofiira molingana ndi gwero la kuwala.Kusiyanitsa pakati pa gawo la laser ndi gawo la kuwala kofiira Mfundo ya gawo loyang'ana laser ndikuti chipangizo chamkati cha laser chimapanga malo opangira kuwala kwa laser, kugunda pepala lowonetsera ndi chipangizo chopangidwa ndi makina, ndiyeno kudalira galimoto yogwedeza kuti igwedeze laser point. mu mzere wa laser ndikuwalitsa pa barcode, kenako ndikuyilemba kudzera mu AD.Chizindikiro cha digito.

2:Ma module owunikira kuwala kofiyira nthawi zambiri amagwiritsa ntchito magwero a kuwala kwa diode ya LED, amadalira zinthu za CCD photosensitive, ndiyeno amazisintha kudzera pazizindikiro zamagetsi.Ambiri a laser sikani zigawo amadalira dispensing guluu kukonza makina chipangizo, choncho nthawi zambiri mosavuta kuonongeka pamene kugwedezeka, ndi pendulum chidutswa kugwa, kotero ife nthawi zambiri tikhoza kuona kuti gwero kuwala scanned ndi laser mfuti amakhala mfundo. pambuyo kugwa., zomwe zimapangitsa kukonzanso kwakukulu.Palibe makina opangira mkati mwa gawo loyang'ana kuwala kofiira, kotero kukana kwa dontho sikungafanane ndi laser, kotero kukhazikika kumakhala bwino, ndipo kukonzanso kwa module yowunikira kuwala kofiira kumakhala kochepa kwambiri kuposa kuwunikira kwa laser. moduli.

3:Kuchokera ku mfundo yakuthupi ya laser ndi kuwala kofiyira: Laser imatanthawuza kuwala kokhala ndi mphamvu yolimbikitsa yamphamvu komanso kufanana kwabwino, ndipo tsopano kuwala kofiira kochuluka kumatulutsa ma LED.Kuwala kofiira si mtundu wa infrared womwe timanena.The infuraredi ofotokozedwa ndi physics ndi mowiriza cheza cha zinthu ndi kutentha.mafunde a electromagnetic, osawoneka.Infrared imaphatikizapo kuwala konse kokhala ndi mafunde akulu kuposa kuwala kofiyira, pomwe laser imatanthawuza kuwala kokhala ndi utali wina wake.Awiriwo alibe mgwirizano wofunikira ndipo sali m'munda womwewo.Laser ndi ma radiation omwe amapangidwa ndi kukulitsa kwa mpweya wolimbikitsa.Infrared ndi gawo la sipekitiramu yokhala ndi mafupipafupi ocheperako komanso mafunde akulu omwe sangathe kuwonedwa ndi maso.Kutalika kwa mafunde kumayambira 0.76 mpaka 400 microns.Kulowa ndi kutsutsa kusokoneza kwa kuwala ndi koipa kuposa kwa laser, kotero laser yakunja ndi yabwino kuposa kuwala kofiira pansi pa kuwala kolimba.
