izindaba

1) Ububanzi besicelo Ubuchwepheshe bekhodi yebha busetshenziswa ezikhathini ezihlukene, futhi abafundi abahlukene bekhodi yebha kufanele kukhethwe. Isibonelo, ukuthuthukisa uhlelo lokuphatha indawo yokugcina impahla, ngokuvamile kuyadingeka ukubala amalabhorethri endaweni yokugcina impahla. Ngokuhambisanayo, isifundi sekhodi yebha siyadingeka ukuthi siphatheke futhi singagcina isikhashana imininingwane ye-inventory esikhundleni sokunqunyelwa ukusetshenziswa phambi kwekhompyutha. Kungcono ukukhetha isifundi sekhodi yebha ephathekayo. Kuyafaneleka. Uma usebenzisa umqoqi webhakhodi emugqeni wokukhiqiza, ngokuvamile kuyadingeka ukufaka isifundi sebhakhodi ezindaweni ezithile ezigxilile emugqeni wokukhiqiza, futhi izingxenye ezikhiqizwayo zifaneleka kakhulu kubafundi bebhakhodi, njengohlobo lwesibhamu se-laser, isithwebuli se-CCD, njll. Ohlelweni lokuphatha ingqungquthela kanye nohlelo lokuhambela ibhizinisi, uhlobo lwekhadi noma isifundi sebhakhodi sohlobo lwe-slot singakhethwa. Umuntu odinga ukungena ngemvume uzofaka isitifiketi esiphrintwe ibhakhodi endaweni yokufunda, futhi umfundi uzoskena ngokuzenzakalelayo futhi anikeze isignali yempumelelo yokufunda. Lokhu kuvumela ukungena okuzenzakalelayo kwesikhathi sangempela. Yebo, ngezikhathi ezithile ezikhethekile, amadivaysi akhethekile okufunda ikhodi yebha angathuthukiswa ukuze ahlangabezane nezidingo.

2) Uhla lokuqopha Uhla lokuqopha olunye uphawu olubalulekile lokukhetha isifundi sebhakhodi. Njengamanje, uhla lokuhlukanisa amakhodi lwabafundi bebhakhodi abakhiqizwe izinkampani ezihlukahlukene luhluke kakhulu. Abanye abafundi bangakwazi ukubona amasistimu amakhodi ambalwa, futhi abanye abafundi bangabona amakhodi angaphezu kweshumi nambili. Lapho uthuthukisa uhlelo lokusebenza lwekhodi yebha, khetha isistimu yekhodi ehambisanayo. Ngesikhathi esifanayo, lapho ulungiselela isifundi sekhodi yebha ohlelweni, umfundi kudingeka abe nomsebenzi wokucacisa kahle izimpawu zalesi simiso sekhodi. Ekuphatheni, ikhodi ye-UPC/EAN ivame ukusetshenziswa. Ngakho-ke, lapho uthuthukisa uhlelo lokuphatha inxanxathela yezitolo, lapho ukhetha umfundi, kufanele akwazi ukufunda ikhodi ye-UPC/EAN. Ohlelweni lweposi nolwezokuxhumana, i-China njengamanje isebenzisa ikhodi ye-matrix 25. Lapho ukhetha umfundi, uphawu lwesistimu yekhodi luqinisekisiwe.

3) Ikhono le-interface Ziningi izinkambu zokusetshenziswa kobuchwepheshe bebhakhodi, futhi kunezinhlobo eziningi zamakhompyutha. Lapho kwakhiwa isistimu yohlelo, imvelo yesistimu yehadiwe ngokuvamile inqunywa kuqala, bese kukhethwa isifundi sebhakhodi esifanele indawo esizungezile. Lokhu kudinga imodi yesixhumi esibonakalayo somfundi okhethiwe ukuze kuhlangatshezwane nezidingo eziphelele zemvelo. Kunezindlela ezimbili zokusebenzelana ezijwayelekile zabafundi bebhakhodi: A. Ukuxhumana kwe-serial. Le ndlela yokuxhumana ngokuvamile isetshenziswa lapho kusetshenziswa uhlelo lwekhompiyutha oluncane noma oluphakathi nendawo, noma lapho isizinda sokuqoqwa kwedatha sithatha ibanga elide ukusuka kukhompyutha. Isibonelo, ohlelweni lokuphatha ukubakhona kwebhizinisi, ikhompuyutha ngokuvamile ayibekwa emnyango nokuphuma, kodwa ibekwe ehhovisi, ukuze ibambe isimo sokuba khona kusenesikhathi. B. Ukulingisa ikhibhodi kuyindlela yesixhumi esibonakalayo edlulisela imininingwane yebhakhodi eqoqwe ngumfundi kukhompuyutha ngokusebenzisa imbobo yekhibhodi yekhompyutha, futhi kuyindlela esetshenziswa kakhulu. Njengamanje, izindlela zekhibhodi ezifana ne-XKAT zivame ukusetshenziswa ku-IBM/PC kanye nemishini yayo ehambisanayo. Imbobo yekhibhodi yetheminali yekhompyutha nayo inezinhlobo ezahlukene. Ngakho-ke, uma ukhetha ukulingisa ikhibhodi, kufanele unake uhlobo lwekhompiyutha ohlelweni lohlelo lokusebenza, futhi unake ukuthi umfundi okhethiwe angakwazi yini ukufanisa ikhompyutha.

4) Izidingo zamapharamitha njengezinga lokufunda kokuqala Izinga lokufunda lokuqala liyinkomba ebanzi yabafundi bebhakhodi, elihlobene nekhwalithi yokuphrinta yezimpawu zebhakhodi, ukuklanywa kwezikhethi zamakhodi kanye nokusebenza kwezithwebuli ze-photoelectric. Kwezinye izinkambu zohlelo lokusebenza, isifundi sekhodi yebha esibanjwa ngesandla singasetshenziswa ukulawula ukuskena okuphindaphindiwe kwezimpawu zekhodi yebha ngabantu. Ngalesi sikhathi, izidingo zezinga lokufunda lokuqala ziqine kakhulu, futhi kuyisilinganiso nje sokusebenza kahle komsebenzi. Emkhiqizweni wezimboni, ukuzithengela wena nezinye izinhlelo zokusebenza, kudingeka izinga eliphezulu lokufunda lokuqala. Inkampani yenethiwekhi evumelana nebhakhodi ihamba emugqeni wokukhiqiza ozenzakalelayo noma ibhande lokudlulisa, futhi lilodwa ithuba lokuqoqa idatha. Uma izinga lokufunda lokuqala lingafinyeleli ku-100%, okwenzekayo kokulahleka kwedatha kuzokwenzeka, okuholela emiphumeleni emibi kakhulu. Ngakho-ke, kulezi zindawo zohlelo lokusebenza, abafundi bekhodi yebha abanezinga eliphezulu lokufunda lokuqala, njengezikena ze-CCD, kufanele kukhethwe.

5) Ukulungiswa Lapho ukhetha idivayisi ukuze kutholwe kahle ububanzi bebha emincane kakhulu efundwa kuyo, ukuminyana kwebhakhodi esetshenziswa kuhlelo lokusebenza kukhetha idivayisi yokufunda enesinqumo esifanele. Uma isetshenziswa, uma ukulungiswa kwedivayisi ekhethiwe kuphezulu kakhulu, isistimu izothinteka kakhulu ama-smudges kanye nokukhishwa kwe-inking kumabha.

6) Izibaluli zokuskena zezakhiwo zingahlukaniswa zibe ukujula kwenkambu yokuskena, ububanzi bokuskena, isivinini sokuskena, izinga lokuqaphela isikhathi esisodwa, izinga lephutha elincane, njll. Ukujula kokuskena kwenkambu kubhekisela kumehluko phakathi kwebanga elikude kakhulu ikhanda lokuskena elikhona. evunyelwe ukushiya indawo yebhakhodi kanye nebanga lephoyinti eliseduze lapho isithwebuli singasondela khona endaweni yebhakhodi ngaphansi kwesisekelo sokuqinisekisa ukufundwa okuthembekile, okungukuthi, uhla lokusebenza olusebenzayo lwesithwebuli sebhakhodi. Amanye amadivaysi okuskena ithebula lebhakhodi awakuniki ukujula kokuskena kwenkomba yensimu ezinkomba zobuchwepheshe, kodwa anikeze ibanga lokuskena, okungukuthi, ibanga elifushane ukuthi ikhanda lokuskena elivunyelwe ukushiya indawo yebhakhodi. Ububanzi beskena bubhekisela kubude obuphathekayo bolwazi lwebhakhodi olungafundwa ugongolo lokuskena ebangeni elithile lokuskena. Isivinini sokuskena sisho imvamisa yesibani sokuskena kwithrekhi yokuskena. Izinga lokuqashelwa kwesikhathi esisodwa limelela isilinganiso senani lamathegi afundwa umuntu oskenwe okokuqala ngqa kwinani eliphelele lomaka abaskeniwe. Inkomba yokuhlola yezinga lokubonwa kwesikhathi esisodwa isebenza kuphela endleleni yokuqaphela ipeni lokukhanya elibanjwa ngesandla. Uma usebenzisa isignali etholiwe kuyaphindwa. Izinga lephutha elincane lilingana nenani lengqikithi yenani lokuhlonza okungamanga. Ohlelweni lwekhodi yebha, izinga lephutha elincane liyinkinga enkulu kunezinga eliphansi lokubonwa kwesikhathi esisodwa.

7) Ubude bophawu lwebhakhodi Ubude bophawu lwebha yisici okufanele sicatshangelwe lapho kukhethwa umfundi. Ngenxa yethonya lobuchwepheshe bokukhiqiza, ezinye izikena zikagesi wesithombe zicacisa ubukhulu bosayizi wokuskena, njengezikena ze-CCD nezikena ze-beam ezihambayo. Kwezinye izinhlelo zokusebenza, ubude bophawu lwebhakhodi bushintshwa ngokungahleliwe, njengenombolo yenkomba yencwadi, ubude bophawu lwebhakhodi kuphakheji yomkhiqizo, njll. Kuzinhlelo zokusebenza zobude obuguquguqukayo, umthelela wobude bophawu lwebhakhodi kufanele kuqashelwe lapho kukhethwa umfundi. 8) Intengo yomfundi Ngenxa yemisebenzi ehlukene yabafundi, amanani nawo awahambisani. Ngakho-ke, lapho ukhetha abafundi, naka isilinganiso sentengo yokusebenza kwemikhiqizo, futhi kufanele ihlangabezane nezidingo zesistimu yesicelo futhi intengo kufanele ibe ngaphansi njengomgomo wokukhetha. 9) Imisebenzi ekhethekile Kudingekile ukuthi ungene kusuka ekungeneni okuningana futhi uxhume abafundi abaningana kukhompyutha eyodwa, ukuze abafundi emnyango ngamunye baqoqe ulwazi futhi bayithumele kukhompyutha efanayo. Ngakho-ke, abafundi kudingeka babe nemisebenzi yokuxhumana ukuze baqinisekise ukuthi ikhompuyutha ingathola ulwazi ngokunembile futhi ibhekane nayo ngesikhathi. Uma uhlelo lokufaka isicelo lunezidingo ezikhethekile zomfundi webhakhodi, kufanele kukhethwe okukhethekile.
