Indlela yokudibanisa i-barcode scanner kwikhompyutha yakho. Iintlobo zeeskrini zebhajethi. Isoftware yeefowuni zebar

Isici esibalulekileyo senkqubo yokulawula ngokuzenzekelayo yesitoreji, igumbi okanye enye ishishini yinkcazo yekhowudi yebhawudi yekhompyutha. Le fowuni iguqula ulwazi olurekhodwe kwilebula yomkhiqizo ngokubetha kwirekhodi kunye negama lemveliso.

Iintlobo zezixhobo zokufunda ibhawudidi

Ngaphambi kokuthenga nokufaka le fowuni, kuya kuba luncedo kuwe ukwazi ukuba yeyiphi i-scanners barcode. Kule ncwadi, loo mizekelo yezixhobo ezinezibane ze-LED kunye nelayisi ziyahluka.

Ifowuni yohlobo lweepenari yokufunda ibhawudidi

I-barcode scanner yekhompyutheni, okanye njengoko ibizwa nangokuthi ipeni, isistim esingabizi kwaye sinokuthenjwa. Xa usebenza, kuyimfuneko ukuyicinezela phezulu, apho ikhowudi isetyenziswe, kwaye uyibambe kuyo yonke iphakheji. Ukufunda ulwazi, isebenzisa umthombo wokukhanya wamandla aphantsi, i-boram yayo idinga ukuwela i khowudi ukususela ekuqaleni ukuya ekupheleni.

Zixhobo zeCCD

I-scanner ye-CCD yebhakhodi yebhakhodi yekhompyutha isebenzisa iteknoloji yokufunda ulwazi ngokusekelwe kumgaqo ofanayo kunye neefaysi. Kukho ezimbini iindidi ze-CCD scanners: uqhagamshelwano kunye nonxibelelwano. Xa usebenzisa umzekelo woqhagamshelwano, umqhubi kufuneka afake i-scanner kwilebula ngekhowudi uze ucinezele iqhosha. I-drawback yangundoqo yale mi scanni kukuba asebenzi kakuhle kwiindawo ezingalinganiyo. Uyilo lwee-scanners ze-CCD ezingabandakanyeli zisebenzisa ama- LED anamandla kunye neentetho ezifayo, ezivumela ukuba bafunde umfanekiso kumgama wama-6 ukuya ku-30 ububanzi.

Umtshini we-Image-scanner, okanye njengoko kuthiwa i-photo scanner, isebenzisa i-matrix yeCCD efanayo njengekhamera okanye iikhamera. Lo mfundi wekhowudi ufunde lonke ulwazi ngokubanzi kwaye akudingeki ukuba uqondiswe ngokukodwa ngokubhekiselele kwiipakethe.

Abafundi beLaser

I-scanner ye-barcode ye-barcode scanner yekhompyutha ilula kwaye kulula ukuyisebenzisa. Indawo yayo yokusebenza ingafikelela kuma-20-110 ngamentimitha, kwaye ezinye zifikelela kwiimitha ezili-10.

Ukuskena i-laser-borrow laser

I-scanner ye-multi-beam scanner laser scanner yakha indawo esebenzayo equkethe imitha emininzi. Ukuze afunde ulwazi, kwanele ukuba ubuncinci beemitha ziwela yonke imivimbo. Ezi zixhobo zizinto ezimbini: idibeneyo, ezifakwe kwi-counter counter, kunye nokucwangciswa.

I-scanner ye-multi-fax scan idibeneyo yakhiwa ngendlela efana ne-scanner esecaleni, eyona nto ehlukileyo eyona nto iyakuthathwa. Indawo yokusebenza, apho iibhascodes (iikhowudi zebar) ziyaqatshelwa, ezo zixhobo ziyancitshiswa xa kuthelekiswa neendawo ezimileyo.

I-bioptic scanner idala indawo ezimbini zokusebenza apho kukho imilasi emininzi yemilasi. Kukho imodeli yala ma-scanners afakwe izikali.

Indlela yokufaka iskena ukuze ufunde ibhakhodi?

Ngaphambi kokusebenzisa i-scanner, kufuneka uyixhume kwikhompyutha yakho kwaye ufake ifayile efunekayo. Kukho iintlobo ezintathu zezixhobo ngendlela edibene ngayo kwikhompyutha:

1. "Kwinqanaba lebhodibhodi."

2. Ukusebenzisa i- COM port port (njengoko kuthiwa yi-RS232).

3. Ukusebenzisa isikhokelo se-USB esenza i-RS232 ibonakalise.

Makhe sicinge ngeenkcukacha zonke iindlela ezintathu zokuxhuma.

Ukuqhagamshelanisa ifowuni ukufunda ibhakhodi "kwindawo yebhodibhodi"

Ibhokisi lebhodibhodi libizwa ngokuba ngu-PS / 2 kwaye lisetyenziselwa ukuxhuma zombini ibhobhobhodi kunye nemouse kwikhompyutha. Ngoku amaninzi amabhodi amabhinki anomnxibelelisi omnye kuphela, kwaye kwii-netbooks zamanqaku kunye nee-laptops azifumaneki.

Ukuxhuma idivaysi yokufunda ikhibhodi, kufuneka uqale ucime ikhomputer, susa ikhibhodi kwikhonkco uze ufake iskena endaweni yoko. Emva koko, kufuneka udibanise ikhibhodi kwi-scanner. Emva kokuba uqhagamshele yonke into, unokuvula i-scanner kunye nekhomputha kwintanethi yombane.

Emva kokuskena ibhakhodi ngefowuni exhotywe nale interface, ikhowudi ifakwe apho isalathisi sitholakala khona, kuba ukuba uyifakile kwikhibhodi. Ngaloo ndlela, ukuba i-scanner ayikwazi ukufunda ikhowudi okanye ayiphumelelanga, ungangena ikhowudi ngqo kwaye usebenzisa ikhibhodi.

Abo babandakanyeka kwiskrini sebhawudi kunye nekhonkco efanayo, kufuneka bawunake ingqalelo kwibhodi yebhodi xa bebona iinombolo zeerari apho kukho iileta. Ngokomzekelo, xa ukulungiswa kwebhodi yebhodi yaseRashiya kuvuliwe, ikhowudi a / n123215654QWE ithathelwe indawo yi f / t123215654TISU.

Le ndlela yoxhumano igcina i- COM enye okanye i-USB, engayinceda xa uxhuma kwikhomputha ezininzi ezininzi izixhobo ezahlukeneyo, umzekelo, ukutshekisha kwiprintter , umshicileli wezimali , izikali kunye nezinye izixhobo eziyimfuneko kumqeshi. Kwakhona i-barcode scanner ne-"keyboard break" idityanisiweyo xa isetyenziselwa inkqubo yebhacodes, ekwazi ukusebenza kuphela kunye nezixhobo ezifanayo.

Ukufakwa kwefowuni yokufunda ibhakhodi nge-COM-interface

I-COM okanye i-RS-232 ichwethi zineenkcukacha ezimbini ezahlukileyo kwi-interface eyodwa, apho izixhobo ezahlukeneyo zingaxhunyiwe kwikhompyutheni yakho. Esi sixhobo senziwe ngefomati, esineemigangatho emibini yezikhonkwane (kumqolo omnye 5, kwenye umqolo 4). Ulwazi oluvela kwiinkalo ezahlukeneyo zangaphandle, xa usebenzisa le ndlela yokuhambisa, uvela kwichungechunge, kunye neengcingo ezimbini. Ngetambo ye-Rx, ulwazi lufaka ikhomputha, kunye ne-Tx, iimpawu zokulawula zithunyelwa kwisixhobo. Ngamanye amaxesha ezinye iinkqubo ezongezelelweyo i-RTS ne-CTS zisetyenziselwa ukusetyenziswa kakuhle kwezi nkqubo. Ngoku unokufumana iibhodi zamabhendi kunye nomxhamli omnye we-RS-232, kodwa kuzo zonke iifayile ze-modern kunye nee-laptops azifumaneki.

Ukufakela i-scanner, kufuneka kuqala iqhagamshelwe kwi-COM port yekhompyutha, emva koko nayiphina inkqubo yokusebenza iya kuyifumana kwaye icele ukufaka abaqhubi abayimfuneko. Zifumaneka kwi disk eza nefowuni, okanye ilayishwe kwi-intanethi. Abanye abenzi beeskripthi banikeza iinkqubo ezikhethekileyo, onokulawula ngayo umthamo wesignali okanye usethe impawu zesevisi.

I-barcode scanner ingaxhunyezwa kwikhompyutha kunye ne-adapter ekhethekileyo esuka kwi-USB ukuya kwi-COM-interface, okufuneka uyifake kwi-USB uze ufake ifayile (inkqubo ekhethekileyo yokukhangela ibhakhodi). Ukuba ifowuni ifakwe ngokufanelekileyo, inkqubo iya kubona umbane ojongene nomgangatho we-RS-232, ukusetyenziswa okungekho okungafani nakakhulu nokusebenza kunye noqhagamshelwano oluqhelekileyo lwe-serial.

I-barcode scanner ne-COM port ingaxhunyezwa kwi- terminal ye-POS, irejista yemali okanye esinye isixhobo esine-RS-232. Kule nxu lumano, i-adapters isetyenziswe kwikhonkco esetyenziswa kwi-barcode reader kwi-RJ-45 (okanye 11). Emva koko, kufuneka uqwalasele izicwangciso zoxhumo kwisixhobo sokuskena.

Kwakhona luhlobo loxhumo lusetyenziswa ukuba inkqubo yokukhangela ikhowudi iphulaphule ichweba kwaye ifake kwindawo efunwayo xa ikhowudi ifunyenwe. Akunandaba nokuba isikhombisi sikuphi.

Indlela yokudibanisa umtshini wekhowudi yekhowudi ngekhompyutheni ye-USB?

Naliphi ikhompyutha yanamhlanje, inetha, i-laptop ehlomele i-USB. Kulo mgangatho, idatha idluliselwa kwiinkalo ngee-two wire, iimbambo ezimbini zinikezela ukunikezela ngombane kumadivayisi axhuma kwi-PC.

Inzuzo ephambili yalezi zixhobo zokufunda ibhakhodi yekhompyutheni isantya esikhulu sokutshintshiselana kwedatha kunye nokukwazi ukuxhuma kwiikhomputha zokusebenza. Iifowuni ezincinci ze-bar code code zidla umbane omncinci, ngoko amandla abo anikezelwa kwi-port yase-USB. Abafundi abaninzi abanamandla kwaye banako ukunikezelwa kwamandla ahlukeneyo.

Ukufakwa kwe-scanner akufanele kubangele ubunzima, kuba zonke iinkqubo zokusebenza zanamhlanje zibona idivaysi yokufunda iikhowudi njengekhibhodi rhoqo, ukwenzela ukuba umsebenzi wabo awufuneki nawuphi na umqhubi. Emva kokuba ibhakhodi ichongiwe, inkqubo iyafaka apho isikhokhelo sitholakala khona.

Uninzi lwee-scan code ze-bar ezixhuma kwi-port yase-USB zinokwenziwa ukuba zisebenze kwimimo apho ziya kulandelelisela i-RS-232 port. Ngokuqhelekileyo, kufuneka ufunde ibhakhodi ekhethekileyo, enikwa imiyalelo kwaye ufake ifayile yokuqhuba. Emva kokudlulisela isixhobo kwimodi yokuboniswa kwe-COM yolwazi, ukusetyenziswa kwayo kuya kufana ne-scanner ejwayelekile esebenza nge standard RS-232.

Kwiinkalo ezininzi zokufunda, kunokwenzeka ukusetha iimpawu eziza kudluliselwa ngaphambi nangemva kwebhakhodi. Ngoko, ngaphambi kokuba ufunde ikhowudi, abasebenzisi abaninzi baya kukhululeka ukuba umseshini ogqithisileyo adlule enye yeempawu ezifana ne-Insert, F1 okanye F9. Ndiyabulela kule nxalenye, inani leenqakrazo ezenziwe ngumsebenzisi zinciphisa kwaye kulula ukusebenza.

Qinisekisa ukuba i-scanner ixhunyiwe kwaye isebenza ngokuchanekileyo

Emva kokuba kufakwe i-barcode scanner, kufuneka uhlolisise ukusebenza kwesixhobo.

Ukuze uqiniseke ukuba i-scanner ixhunyiwe "kutyhulwa kwebhobhodi" okanye ngekhonkco ye-USB, isebenza ngokuchanekileyo, kufuneka uqale nayiphi na umhleli wombhalo, umzekelo, "I-Notepad", kwaye uzame ukuskena ikhowudi. Ukuba abalinganiswa bevela kwisikrini, ifowuni isetyenziswe ngokuchanekileyo.

Ukuba ifowuni yakho yokufunda ibhawudidi ixhunyiwe kwi-RS-232 okanye isebenza nge-USB kwimo ye-COM-interface, ngoko kufuneka uqale uqale nayiphi na inkqubo yesigxina kwaye uyiqwalasele kwi-port oyifunayo. Emva koko, unokufunda ikhowudi kwiphakheji. Ukuba ulungiswe kakuhle, imifanekiso ekufuneka ifundwe ibonakale kwisikrini.
