Mabhaodhi scanner akasiyana anodaidzwa kunzi mabhakodhi ekuverenga, mabhaodhi scanner, mabhaodhi scanner, mabhakodhi scanner uye mabhakodhi scanner zvinoenderana nemazita echivanhu. .Inowanzo shandiswa mumaraibhurari, zvipatara, zvitoro zvemabhuku uye masupamaketi, senzira yekupinza yekukurumidza kunyoresa kana kugadzirisa, inogona kuverenga zvakananga ruzivo rwebhakodhi pamusoro pekurongedza kwekunze kwezvinhu kana zvakadhindwa, uye kuipinza muhurongwa hwepamhepo.

1. Barcode scanner mudziyo unoshandiswa kuverenga ruzivo rwuri mubhakodhi. Chimiro chebhakodhi scanner kazhinji zvikamu zvinotevera: chiedza chinobva, chigadziro chekugamuchira, photoelectric conversion components, decoding circuit, computer interface.

2. Nheyo yekutanga yekushanda kwebarcode scanner ndeye: Chiedza chinobudiswa nechiedza chinovhenekera pachiratidzo chebhakodhi kuburikidza neoptical system, uye chiedza chinoratidzwa chinoratidzwa pane photoelectric converter kuburikidza ne optical system kuti ibudise chiratidzo chemagetsi, uye chiratidzo chinowedzerwa nedunhu. Iyo analog voltage inogadzirwa, inofananidzwa nechiedza chinoratidzwa pachiratidzo chebhakodhi, uye yobva yapepetwa nekuumbwa kuita sikweya wave chiratidzo chinoenderana neiyo analogi chiratidzo, icho chinodudzirwa neiyo decoder sechiratidzo chedhijitari chinogona kugamuchirwa zvakananga. nepakombiyuta.

3. Kazhinji barcode scanners anowanzo shandisa tekinoroji nhatu dzinotevera: light pen, CCD, uye laser. Vese vane zvazvakanakira uye zvazvakaipira, uye hapana scanner inogona kuva nezvakanakira mune ese maficha.
