Yikuphi ukwehluleka kwesoftware evamile yokuthwebula iminwe nokuhluleka kwehardware?

1. Abanye abasebenzisi bavame ukwehluleka ukuphumelela ukuqinisekiswa kweminwe, ukuthi bangayixazulula kanjani le nkinga
Lezi zimo ezilandelayo zingenza kube nzima noma zisebenze kwabanye abasebenzi ukuthi basebenzise iminwe yababekhona:
Ama-①fingerprints kweminye iminwe abushekelwe.

② Kunamapholi amaningi kakhulu eminwe, evame ukuguquka.

Abahlinzeki abanezinwele ezinzima eminweni yabo kanye neminwe engaziwa ingasusa iminwe bese irejista kabusha, noma ubhalise omunye umunwe. Lapho ubhalisa iminwe yeminwe, abasebenzisi abanjalo badinga ukukhetha iminwe esezingeni eliphakeme, bese bezama ukwenza umunwe ngokuthinta umunwe ngangokunokwenzeka. Indawo yekhanda lokutholwa likhulu. Ngemuva kokuthi ukubhaliswa sekuqediwe, yenza isivivinyo sokuqhathanisa. Kunconywa ukubhalisa iminwe embalwa yokusekelayo. Ngaphezu kwalokho, isithwebuli sethu sihlinzeka nge-1: 1 indlela yokuqhathanisa nomsebenzi wokubakhona kwephasiwedi ngale nhloso. Ungasetha laba basebenzi ukuthi basebenzise i-1: 1 indlela noma iphasiwedi yokuba khona.
2. Lapho isithwebuli singakwazi ukuxhumana, iziphi izizathu?
Ukuhlelwa kwe-Port yePortom akulungile, futhi i-Port yezokuxhumana ekhethiwe akuyona indawo yangempela ye-com esetshenzisiwe.
Isilinganiso se-baud ye-Port Port of the computer yehlukile kwinani lokubeka isilinganiso seBaud lesithwebuli.
③ Isithwebuli asixhunyiwe ekunikezelweni kwamandla noma okuxhunywe kwikhompyutha.
Scanner ixhunyiwe kepha ayivulwanga.
⑤ Inombolo ye-terminal exhunyiwe ayilungile.
⑥Umugqa wedatha noma isiguquli asikwazi ukuxhumana.
⑦ Imbobo yekhompyutha yephuliwe iphukile.
3. Ngemuva kokuthi isithwebuli sixhunyiwe ekuhlinzekeni kwamandla futhi sivuliwe, isibonisi se-LCD asiphelele, kwesinye isikhathi kuphela esibonisiwe, futhi kwesinye isikhathi isikrini sifiphala, yini ukuthi ungayixazulula kanjani
①Ibhodi eliyinhloko liphukile.
Uma kunenkinga ngezimpawu zangaphakathi ze-liquid Crystal, udinga ukuxhumana nomhlinzeki kanye nokubuyisa ukulungisa.
4. Ungayisusa Kanjani Umphathi We-Scanner
Ungasebenzisa isithwebuli ukuxhumana nekhompyutha. Ngemuva kokuxhumana okuphumelelayo, faka ithebhu yokuphathwa kwe-Scanner bese uqhafaza inkinobho ethi Susa Imenenja ukuze ususe Umphathi We-Scanner. Ngemuva kokuxhuma, ungafaka imodi yemenyu yeScanner.
5. Yisiphi isizathu sokushaye ikhwela lapho isithwebuli sixhunyiwe
① Uma kwenzeka okungenhla kwento esebenzisa ukuxhumana kwe-RS-232, isilinganiso se-baud sekhompyutha asihambisani nokuhlelwa kwesilinganiso se-baud sesithwebuli.
Kusetshenziswa ukuxhumana kwe-RS-485, imigqa emibili yomugqa wokuxhumana wokuguqula ingahle ibuyiselwe emuva, noma imigqa emibili ingahle ibambene ndawonye.
6. Ngemuva kokuthi isithwebuli sivuliwe, siyaqhubeka sibonisa sicela ucindezele umunwe wakho futhi, yini inkinga nokuthi ungayixazulula kanjani
① esebenzisa isikhathi eside, ingaphezulu lekhanda lokuqoqa liba olungcolile noma lihlanzekile, elizokwenza ukuthi i-Light Likani iqiniso licabange ukuthi kukhona umunwe ebusweni, futhi ngeke kudlule, kulokhu, ngakho-ke le nkinga yenzeka, kulokhu Ungasebenzisa itheyiphu yokuzithela ukuze uyibambe iqoqa ukungcola ebusweni bekhanda.
Ukuxhumeka kwekhanda lokuqoqwa kweminwe kukhululekile noma kukhululiwe.
③ I-chip board yephuliwe. Uma kunezizathu ezimbili zezinto ② ne-③, udinga ukuxhumana nomphakeli ukuthi afake isicelo sewaranti.
7. Lapho usebenza ekuphathweni kwe-terminal, ayikho inkinga yokulanda idatha yeminwe nephasiwedi, kepha uma ufunda irekhodi lababekhona, lishukumisela ukwehluleka noma iphutha phakathi. Ngingayixazulula kanjani?
Lesi simo singahlobene nentambo yedatha, noma isiguquli, noma imbobo yekhompyutha. Ngalesi sikhathi, unganciphisa izinga lokuxhumana phakathi kwesithwebuli nekhompyutha, ngokwesibonelo,, likubeke ku-19200 noma 9600, bese lilifunda.
8. Kungani kungekho msindo ukufika lapho ukhona
Mhlawumbe isipikha siphukile noma i-chip yomsindo yephuliwe.
9. Kungani isithwebuli singakwazi ukufaka isikhombimsebenzisi sokufika lapho isithwebuli sinikwa amandla?
Uyacelwa ukuthi ubheke ukuthi ikhebula lekhanda leminwe lixhunyiwe kahle, noma ikhanda leminwe liphukile. Uma kuqinisekiswa ukuthi okungenhla konke okuhle, sicela usibuyisele emuva ukuze silungiswe.
10. Kungani isithwebuli kwesinye isikhathi sincipha
Uma kunemizuzu embalwa ngesonto, kungenzeka ukuthi ikristalu yewashi iphukile.
11. Kungani isithwebuli siqala kabusha ngemuva kwesikhathi ngemuva kokuhluleka kwamandla, futhi isibonisi sesikhathi asonakele
Mhlawumbe i-MCU iphukile, sicela uyibuyisele efektri ukuze ilungiswe.
12. Kungani isithwebuli siqala kabusha ngemuva kwesikhathi ngemuva kokuhluleka kwamandla, futhi isikhathi sizobuyela ku-zero
Mhlawumbe ibhethri lewashi liphukile, sicela ubuyele efektri ukuze ulungiswe.
13. Ukukhanya kweqoqo akuvuliwe
Kungenzeka ukuthi umugqa wedatha awuxhunyiwe kahle, xhuma umugqa wedatha.
14. Kungani kungekho msindo wezinkinobho futhi awukho umsindo wokuba khona
Kungaba yinkinga ye-buzzer, uphondo, noma i-wiring.
