Indlela ukuxhuma isithwebuli ibhakhodi kukhompyutha. Izinhlobo ibhakhodi scanner. Izinhlelo ngoba barcodes

Into ebalulekile othomathikhi ukuphathwa ishede, agcine noma ezinye ibhizinisi kuyinto isithwebuli ibhakhodi kukhompyutha. Le divayisi iguqula ulwazi eqoshiwe kwilebula umkhiqizo ngosizo imivimbo kurekhodi enegama komkhiqizo.

Izinhlobo amadivayisi ukufunda ibha amakhodi

Ngaphambi kokuba uthenge futhi ufake kule divayisi, kuyoba usizo ukwazi yiziphi lwemishini ibhakhodi. Esikhathini izincwadi, amadivayisi njenge ababonakali ngezikhundla imodeli LED kanye laser ukukhanya.

kudivayisi Down sokufunda ibha amakhodi

Wand ibhakhodi Enani kukhompyutha, noma njengoba ibizwa ipeni - kuyinto kudivayisi engabizi futhi enokwethenjelwa. Emsebenzini udinga cindezela kuhle kwamanzi, okwabangela ikhodi bese uyibambe kuwo wonke iphakethe. Ukuze ufunde ulwazi, lisebenzisa umthombo wokukhanya of ongaphakeme amandla ugongolo esidingeka ukuwela ikhodi kusukela ekuqaleni kuze kube sekupheleni.

kudivayisi be-CCD

Aphathwayo be-CCD ibhakhodi Enani sokufunda kukhompyutha usebenzisa ulwazi ubuchwepheshe esekelwe isimiso esifanayo njengoba kule amafeksi. Be-CCD scanner zaziwa izinhlobo ezimbili: contact futhi imininingwane yokuxhumana. Lapho usebenzisa i-contact Operators kudingeka unamathisele Enani ilebula nekhodi bese ucindezela inkinobho. I ethile eyinhloko scanner ezinjalo azisebenzi kahle ezindaweni engalingani. Umklamo yokuxhumana be-CCD scanner zisebenzisa ephezulu amandla LED futhi photosensors ebucayi, siyivumele ukuba ufunde isithombe at ibanga 6 kuya ku-30 amasentimitha.

Image isithwebuli, noma njengoba bebizwa kanjalo isithombe-Enani isebenzisa okufanayo be-CCD behleliwe njengabantu abayakulwa, ikhamera noma i-camcorder. Lokhu isithwebuli ikhodi ofunda lonke ulwazi ngokuphelele futhi akudingekile ukuba ngokukhethekile ukukhomba kwikhava.

kudivayisi Laser ukuze ulifunde

Ngesandla ikhodi laser ibha Enani computer kuyinto elula futhi kulula ukusebenza. endaweni yayo ukusebenza ongafinyelela 20-110 amasentimitha, futhi abanye abafika kwabangu-10 amamitha.

Multibeam laser scanner

Elimile multi-projector laser isithwebuli yakha endaweni umsebenzi, esakhiwa imishayo eziningana. Ukuze ukwazi ukufunda ulwazi, kwanele ukuthi okungenani umuntu oyedwa sebuningini imisebe sawela wonke imivimbo. amadivaysi ezinjalo ezinhlobo ezimbili: esakhelwe, okuyinto ukufakwa counter yemali, futhi lelivakalako.

Kuhlanganiswe multi-ugongolo isithwebuli kuhlelwe kanye umile, ikakhulu ukuhlukanisa ukuthi kungathatha. Le ndawo abasebenza lapho kukhona ukuqashelwa bar amakhodi (bar amakhodi), amadivayisi njenge kuyehla uma iqhathaniswa umile.

isithwebuli Bioptic kudala ezindaweni ezimbili emsebenzini lapho kukhona sebuningini laser imishayo. Kukhona amamodeli we-scanner ifakwe izinsimbi.

Indlela ukusetha isithwebuli ukufunda ikhodi ibha?

Ngaphambi kokusebenzisa i-, kudingeka ukuba uxhume kukhompyutha yakho bese ufake isofthiwe ezidingekayo. Kunezinhlobo ezintathu amadivayisi ngendlela yokuxhuma kukhompyutha yakho:

1. "nhlonhlo ikhibhodi".

2. Ukusebenzisa le serial COM port (njengoba ibizwa RS232).

3. Usebenzisa-USB izimbobo, okuyinto emulates interface RS232.

Ake sicabangele izindlela ezintathu ukuxhuma.

Ixhuma kudivayisi ukufunda ikhodi ibha "Ikhibhodi nhlonhlo"

Ikhibhodi ye-port ngokuthi PS / 2 futhi isetshenziselwa uxhumano PC njengoba ikhibhodi negundane. Manje, motherboards abaningi babe isixhumi futhi yesimanje netbooks eyodwa kuphela ezifana nezincwadi, ke engekho.

Ukuze uxhume ikhibhodi ukufunda kudivayisi, kumele uvule kuqala kukhompyutha off, susa i-plug kusukela ikhibhodi bese ufaka endaweni yaso Enani. Khona-ke kudingeka ukuba uxhume ikhibhodi isithwebuli. Uma uxhumeke, ungavula i nekhompyutha ku-samandla.

Ngemva kuthwetshulwa idivayisi ibhakhodi ifakwe le esibonakalayo, ikhodi ifakwe lapho isikhombisi, njengoba uma uyithayiphe ku ikhibhodi. Ngakho, uma i abakwazi ukufunda ikhodi noma aphume oda, ungakwazi faka ikhodi ngokuqondile ikhibhodi.

Labo ababenza idivayisi ibhakhodi ukuskena nge esibonakalayo efanayo, kufanele sinake kusakhiwo kwekhibhodi lapho ukuqashelwa nenombolo ye-serial, esesikhundleni izinhlamvu. Ngokwesibonelo, lapho kufakwe Russian isendlalelo sekhibhodi esikhundleni sekhodi / n123215654QWE kubhekwe lb / t123215654YTsU.

Le ndlela uxhumano kusindisa port COM noma USB, okuyinto kungaba usizo lapho yokuxhuma ikhompyutha eziningi kumadivayisi ezahlukene, ezifana iphrinta amasheke, kwezimali amadivayisi iphrinta, izikali namanye amadivayisi ezidingekile ekusebenzeni cashier. Futhi isithwebuli ibhakhodi ne uxhumano "Ikhibhodi nhlonhlo" lisetshenziswa uma usebenzisa isofthiwe ibhakhodi ukuthi uyakwazi ukuthi isebenze kuphela nama amadivaysi ezinjalo.

Ukubeka idivayisi ukufunda ikhodi ibha COM-interface

COM noma RS-232 port - lawa selisho ezimbili ezihlukene esibonakalayo olulodwa lapho kwikhompyutha siqu, ungaxhuma ezihlukahlukene amadivaysi. Lokhu isixhumi amisiwe njengoba isikwele, esakhiwa ezimbili zezitokisi ezingu-izikhonkwane (5 umugqa owodwa, omunye 4). Ulwazi olusuka ezihlukahlukene kumadivayisi angaphandle ngokusebenzisa le ndlela ukudluliswa ihlinzekwa ngokulandelana kwi izintambo ezimbili. Ngu wire idatha Rx enikeziwe kukhompyutha, futhi Tx izimpawu ukulawula ngocansi kudivayisi. Ngezinye izikhathi eziwasebenzisayo imigqa eyengeziwe RTS kanye CTS for ukusebenza efanele izinhlelo. Kusengenzeka ukuthola ibhodi uhlelo nomunye RS-232 isixhumi, kodwa kuwo wonke netbooks yesimanje nezincwadi, ke engekho.

Ukufaka isithwebuli, kufanele kuqala ukuxhuma COM PC sika-port, bese yiluphi uhlelo lokusebenza futhi ngeke akucele ukuba ukufaka abashayeli adingekayo. Betholakala khona, noma kudiski eliza idivayisi noma kulayishiwe kusuka Inthanethi. Ezinye Abenzi scanner ukuhlinzeka izinhlelo ezikhethekile ngawo ungakwazi ukulawula ivolumu alamu, noma ukusetha izinhlamvu ezikhethekile.

Isithwebuli kungenziwa exhunywe kwikhompyutha usebenzise adaptha ekhethekile USB esibonakalayo phezu COM-barcodes ukuba ifakwe le-USB bese ufake umshayeli (ekhethekile ibhakhodi uhlelo isithwebuli). Lapho ukufakwa lesifanele zedivayisi ohlelweni kuthola virtual esibonakalayo RS-232 ajwayelekile, akasebenzisi ihluke kakhulu kwethi ukusebenza ezivamile uxhumano serial.

Barcode Enani ne COM-port kungenziwa exhunywe kwi- ukuphela Pos, yemali, noma yimuphi omunye imishini ukuthi ifakwe interface RS-232. Ukuze ukusetshenziswa okunjalo zezakhi we isixhumi adaptha ukuthi isetshenziswa idivayisi ofunda amakhodi bar RJ-45 Isixhumi (noma 11). Ngemva kwalokho, uxhumano nemingcele ezidingekayo ukulungisa scan idivayisi.

Lolu hlobo uxhumano isetshenziswa lapho isithwebuli ikhodi Uhlelo kuyinto ngokukhethekile ulalela port nalapho ikhodi itholwa, ifaka ke endaweni efanele. Akunandaba lapho isikhombisi okwamanje itholakala.

Indlela ukuxhuma isithwebuli, ikhodi bar computer nge esibonakalayo-USB?

Noma iyiphi ikhompuyutha kwanamuhla, netbook, notebook ifakwe echwebeni USB. Kulesi standard, idatha idluliselwa serially nge izintambo ezimbili, izintambo zikagesi ezimbili ezisetshenziswa sokusebenzisa voltage kudivayisi, okuyinto uxhumeke kwi-PC.

Inzuzo enkulu yale amadivayisi ukufunda computer ibhakhodi kuyinto ngesivinini esiphezulu yabo ukushintshanisa kwe-data kanye nekhono ukuxhuma ikhompyutha ukugijima. Small ngesandla ibhakhodi scanner kudle esincane amandla, ngakho-ke kunikwe amandla kusuka echwebeni USB. Multiplanar umfundi namandla kakhulu futhi ngenxa yalokho nginemibuzo ehlukile ugesi.

I obandayo isithwebuli kufanele kube kuqondile, kusukela zonke yesistimu yokusebenza yesimanje ibona idivayisi ukufunda amakhodi njengendlela ikhibhodi evamile, ngakho umsebenzi wabo, bona akudingeki ukuba abashayeli. Uma ibhakhodi ihlolelwa, uhlelo ifaka ke lapho isikhombisi itholakala.

scanner Abaningi barcodes axhunywa ku echwebeni USB, ungenza ukusebenza imodi lapho bayokwazi nezici RS-232 port. Ngokuvamile kudinga ukuba sicabangele ikhodi ibha ekhethekile kunikezwe imiyalelo bese ufake umshayeli port ebonakalayo. Ngemva idivayisi ngokudluliswa kwesinghonghoyilo sabo ukulingisa imodi COM-interface, ukusetshenziswa kwalo kuyafana ngoba isithwebuli ezivamile esisebenza ngokungaguquguquki njengomthetho RS-232 ejwayelekile.

Amadivayisi amaningi ngoba schityvaniyasuschestvuet ikhono ukusetha abalingisi izodluliselwa ngaphambi nangemva ibhakhodi. Ngakho, ngaphambi kokufunda ikhodi, abasebenzisi abaningi ukuthi isiphi isikhathi esikahle uma isithwebuli lidlule yomunye wabalingiswa ezifana Faka, F1 noma F9. Ngenxa yalesi kungenzeka ukunciphisa isibalo ukuchofoza izinkinobho phezu opharetha ikhibhodi lula umsebenzi walo.

Iqinisekisa lwenethiwekhi nokusebenza isithwebuli

Emva ukufakwa isithwebuli ikhodi ibha sekuphelile, kubalulekile ukuhlola ukusebenza idivayisi.

Ukuze siqiniseke ukuthi i-ixhunyiwe "e ikhibhodi Wedge" noma USB-isixhumi ukuze isebenze kahle, udinga ukusebenzisa noma iyiphi Umhleli wombhalo ezifana "incwajana", bese uzama ukuskena ikhodi. Uma izinhlamvu esibukweni, idivayisi ilungiswe kahle.

Uma idivayisi yakho ukufunda barcodes exhunywe RS-232 noma usebenza nge-USB ukuze COM-interface mode, pre-isidingo ukusebenzisa noma yiluphi uhlelo esibulalayo bawubeka echwebeni lesifanele. Ungabese ukufunda ikhodi kusukela iphakethe. Lapho amisiwe kahle, isikrini kumele kuvele izinhlamvu esifundekayo.
