Decoding Barcode. anobatsira mashoko

Nyaya ino ichatsanangura chii decoding bhaa code, naro husava kurekodha mashoko.

Barcode anonzi mashoko encoded inoverengwa chaiwo namano. It rinoshandisirwa pasuru, zvinoita sokunge kurohwa. Kubhawa yekubvuma anogona encode mashoko nezvevamwe zvinokosha parameters chezvinhu.

The inonyanya EAN (European Coding maitiro) uye American Universal Product Code UPC.

Sei decoding mubhawa yekubvuma? More pamusoro pazasi.

Mamiriro ari encoded mashoko zvinosanganisira:

- nyika mavambo code, kazhinji zviviri kana zvitatu digits;

- mugadziri wacho bumbiro - a digits mana kana mashanu - zvose zvinoenderana Kureba nyika remitemo;

- zvimwe nhamba shanu - zita chigadzirwa, ayo ruvara, uremu, kukura, uye nevatengi zvivako;

- okupedzisira digits masere - kudzorwa, iro rinoshandiswa ritsigire yakarurama kuverenga Barcode scanner.

Dzimwe nguva pane chiratidzo kurudyi ">", izvo zvinoreva kusunungurwa kwenhumbi pasi rezinesi.

Decoding Barcode inopa yakawanda mashoko anokosha pamusoro chigadzirwa.

Kuti asimbise wechokwadi bars remitemo kana kwete, zvinotevera Masvomhu anofanira ashandiswe. Wedzerai yose nhamba kuti dziri pasi kunyange pavhu. Zvadaro vawande kunoguma pakuverengwa vatatu. Kuponesa mugumisiro, watichadana kuti "X".

Uyezve akapeta nhamba (asi pasina bhuku nhamba) yakarongwa zvinoshamisa munda, mari iri kuwedzera nhamba "X" vakawana kare. Uwandu, waitova (isu vanouti «YZ»), pasi chete Z. Next, isu riite nyore kuita: 10- Z.

Kana nhamba kuti yave vagamuchira, sezvaiitwa checksum akanyorwa Barcode, chinhu chacho chiri zvechokwadi. Kana asingadi kunowirirana, ipapo chigadzirwa akanga pasina maererano nomutemo wakaita.

Decoding Barcode anogona kuzivisa mashoko pamusoro nyika umo nhumbi yakabereka, iyo kuziva nhamba boka, zita chigadzirwa.

Izvi yeEncoding ruzivo unoshandiswa rose. Saka, funga marudzi zimbabwe.

Mumwe nyore Barcode ndiye "2 5". Zviratidzo anoratidza nhamba kubva razero mapfumbamwe, pachayo rine mitsetse shanu, vaviri vari hwayo, uye nhatu - yakatetepa.

Nemaburi Kurohwa zvisina atakure Data uye kazhinji pakakoromoka upamhi vakaenzana noupamhi rakamanikana bhaa. Bumbiro iri, kunze digits, rine mabhii "kutanga" uye "mira". Kurohwa matatu chete kushandiswa kwavo nomufananidzo, izvo zviviri vari rwakafara. Makwanza mashoko regai kutakura bumbiro "2 of 5" dzinotevedzana discrete, saka kuti nyore kudhinda uye yaibva dzakaonekwa kukanganisa chete.

Pari muzariro bumbiro zvinhu kunogonawo kuva multi-mavara.

Code "Codabar" chinhu discrete semielementnym Barcode. Rine nhamba kubva razero mapfumbamwe, zviratidzo "-" uye "+", "/", ":" 4 digits "kutanga / kumisa" uye dhora chiratidzo ".". rambidza "Codabar" bumbiro kuruboshwe uye kodzero dziri shoma zviratidzo. The chiratidzo anotarira yakaita mana sitiroko uye zvitatu dzezvimwe.

Bar bumbiro saka "39" inonzi nokuda sechivako mufananidzo kutaurwa "3 9" vari wakafara apo zvinhu zvitatu (rimwe pakakoromoka uye vaviri ronda) pfumbamwe wakamanikana - mamwe matanhatu. Bumbiro Iri hwakavimbika zvakakwana, uye chii hworatidza zvimunakire. Uyewo, rakavimbika bumbiro yakadaro inogona yakawedzera achiwedzera kudzorwa hunhu iri hunhu.

Barcode chigadzirwa inzira pakunyora mashoko.

A nzvimbo inokosha pakati siyana bhaa-Coding hurongwa anotora kubhawa bumbiro "93". With chete akagadzirwa mashoko digits sezvo bumbiro "39", rinogona yakakwirira arambe achirema mufananidzo vatambi. Makumi mana namasere zviratidzo vanotaurwa muna "93" bumbiro remitemo. Zvinosanganisira zviratidzo "kutanga / kumisa" kudzora chiratidzo zvina makumi matatu digits ari bumbiro "39".

Vachikwanisa encode zana namakumi maviri navasere yakasiyana mabhii chokuita zita kubhawa remitemo "128". Bumbiro remitemo "128" - a inondimukira uye kuramba romutemo. zviratidzo zvayo zvinosanganisira mbariro matatu dzezvimwe, uye mumwe nomumwe kureba modules gumi.

Takurukura mamwe marudzi bhaa Codes kuti zvinowanikwa munyika.
