Principium et selectio wireless barcode scanner


Principium wireless barcode scanner

est barcode scanner pluribus constat modulis barcode intuens moduli Plures modi intuendi in barcode intuens modulus

1. Laser unus modulus dimensionis barcode intuens

Principium laseris unius dimensionis barcode technologiae intuens est: primo, laser trabes ex machina generatur, et deinde laser linea intuens ex speculo rotante formatur. Laser linea intuens in barcode lustratur, et rursus ad machinam transmittitur, et in signum electrica per machinam photographematicam intra machinam convertitur. Praecipuae notae laseris barcode moduli intuens longam distantiam lectu sunt, facultas perspiciendi cinematographici tutelam, ac legendi diligentiam ac velocitatem.

2. CCD una dimensiva barcode moduli intuens moduli

Principium fundamentale CCD barcode una dimensiva intuens technologiam est quod CCD elementum iniuncta fabrica fabricam mechanismum movendi trabem substituere potest, et symbolum barcode automatice lustrari potest, nulla compage movens addita. . In symbolo barcode imaginem lucis semitam in CCD lucis sentiendi fabrica ordinata (photodiode ordinata), Intensio signi electrici alia est cum reflectitur in fabrica photographica. Per gyrum scandens, signum electricum respondente ampliatur, formatur et output, et tandem signum electricum symbolo barcode respondens formatur. Ad certam resolutionem ordinatio elementorum photoelectricorum densitas curabit ut elementum angustissimum in symbolo barcode saltem elementis photoelectricis 2—3 veletur, et longitudo ordinatio imaginem totius operire possit. barcode symbolum. Communes numeri ordinati sunt 1024, 2048, 4096, etc. Imago unius dimensionis barcode moduli

modo intuens, praestantissima imaginatio barcode dimensionalis technologiae scandens est modus imaginandi CMOS machinis optical.

4. Laser imago ducitur dimensiva duo barcode intuens moduli

Dingula dimensiva barcode intuens moduli laseris ductus imaginis imaginem technologiae imaginandi genus adoptat, imaginatio in sensorem semiconductorem per lens optical, et imaginum notitias per conversionem analog / digital conversionem (CCD Technology) vel recta digitization (CMOS Technology). CMOS collectae imaginis notitias ad systema computatrale embedded processus mittit. In processu contentorum processus imaginis, decoctionis, erroris correctio et decoctionis includit. Denique eventus processus per communicationem instrumenti traducitur.

The two-dimensional barcode scanning module of laser guided image adopts image type imaging technology, imaging on semiconductor sensor through optical lens, and outputting image data through analog / digital conversion (CCD Technology) or direct digitization (CMOS Technology). CMOS sends the collected image data to the embedded computer system for processing. The processing contents include image processing, decoding, error correction and decoding. Finally, the processing results are transmitted through the communication interface.
