Izikrini zokubonisa ze-LEDyimikhiqizo kagesi, futhi ngezinye izikhathi kungase kube nezinkinga ezithile.Ngezansi, sizokwethula izindlela ezimbalwa ezijwayelekile zokuxazulula inkinga.
01 Yini isizathu semizuzwana embalwa yemigqa ekhanyayo noma isithombe esifiphele esibukweni se-LED uma sivuswa okokuqala?
Ngemva kokuxhuma isilawuli esikhulu sesikrini kukhompyutha, ibhodi lokusabalalisa le-HUB, nesikrini kahle, kuyadingeka ukunikeza a+5V ukunikezwa kwamandlakusilawuli ukuze kuqinisekiswe ukusebenza kwayo okuvamile (ngalesi sikhathi, ungayixhumi ngokuqondile ku-voltage engu-220V).Okwamanje amandla okukhanyisa, kuzoba namasekhondi ambalwa emigqa ekhanyayo noma "isikrini esifiphalisiwe" esikrinini, okuyizimo ezivamile zokuhlola, okukhumbuza umsebenzisi ukuthi isikrini sesizoqala ukusebenza ngokujwayelekile.Phakathi kwamasekhondi angu-2, lesi simo sizonyamalala ngokuzenzakalelayo futhi isikrini sizongena kumodi yokusebenza evamile.
02 Kungani ingakwazi ukulayisha noma ukuxhumana?
Izizathu zokwehluleka kokuxhumana nokwehluleka kokulayisha zicishe zifane, okungase kubangelwe izizathu ezilandelayo.Sicela uqhathanise izinto ezisohlwini nomsebenzi:
1. Qinisekisa ukuthi ihadiwe yesistimu yokulawula ivulwe ngendlela efanele.
2. Hlola futhi uqinisekise ukuthi ikhebula le-serial elisetshenziswe ukuxhuma isilawuli iwumugqa oqondile, hhayi umugqa we-crossover.
3. Hlola futhi uqinisekise ukuthi intambo yoxhumano lwembobo ye-serial ayilungile futhi akukho ukuxega noma ukuhlukaniswa kuzo zombili iziphetho.
4. Qhathanisa isofthiwe yokulawula isikrini se-LED nekhadi lokulawula olikhethile ukuze ukhethe imodeli yomkhiqizo efanele, indlela yokudlulisa, inombolo yembobo yomkhiqizo, kanye nezinga le-serial transmission.Setha ikheli kanye nezinga lokudluliswa kwe-serial ku-hardware yesistimu yokulawula ngendlela efanele ngokomdwebo onikeziwe wokushintsha ukudayela ku-software.
5. Hlola ukuthi ikepisi le-jumper likhululekile noma lihlukanisiwe;Uma ikepisi le-jumper lingaxegi, sicela uqinisekise ukuthi isiqondiso sekepisi se-jumper silungile.
6. Uma ngemva kokuhlola nokulungiswa okungenhla, kusenenkinga ngokulayisha, sicela usebenzise i-multimeter ukukala ukuthi ingabe imbobo ye-serial yekhompyutha exhunyiwe noma i-hardware yesistimu yokulawula yonakele, ukuze uqinisekise ukuthi kufanele ibuyiselwe kumkhiqizi wekhompyutha. noma i-hardware yesistimu yokulawula ukuze ihlolwe.
03 Kungani isikrini se-LED sibonakala simnyama ngokuphelele?
Enqubweni yokusebenzisa amasistimu okulawula, kwesinye isikhathi sihlangabezana nokwenzeka kwezikrini ze-LED ezibonakala zimnyama ngokuphelele.Isenzakalo esifanayo singabangelwa izizathu ezihlukahlukene, ngisho nenqubo yokushintsha isikrini ibe mnyama ingase ihluke kuye ngemisebenzi ehlukene noma izindawo.Isibonelo, ingase ibe mnyama ngesikhathi ikhanyisa, ingase ibe mnyama ngesikhathi sokulayisha, noma ibe mnyama ngemva kokuthumela, njalo njalo:
1. Sicela uqinisekise ukuthi zonke izingxenyekazi zekhompuyutha, okuhlanganisa nesistimu yokulawula, ivulwe ngendlela efanele.(+5V, musa ukuhlehla noma uxhume ngokungalungile)
2. Hlola futhi uqinisekise ngokuphindaphindiwe ukuthi ikhebula le-serial elisetshenziswe ukuxhuma isilawuli ikhululekile noma ivaliwe.(Uma iba mnyama ngesikhathi sokulayisha, kungenzeka ukuthi kungenxa yalesi sizathu, okungukuthi, iphazamiseka ngenxa yemigqa yokuxhumana exegayo phakathi nenqubo yokuxhumana, ngakho isikrini siba mnyama. Ungacabangi ukuthi umzimba wesikrini awunyakazi. , futhi imigqa ayikwazi ukuxega. Sicela uzihlolele yona, okubalulekile ekuxazululeni inkinga ngokushesha.)
3. Hlola futhi uqinisekise ukuthi ibhodi lokusabalalisa le-HUB lixhunywe esikrinini se-LED kanye nekhadi lokulawula eliyinhloko lixhunywe ngokuqinile futhi lifakwe libheke phansi.
04 Isizathu sokuthi kungani sonke isikrini seyunithi yebhodi singakhanyi noma singakhanyi ngokulufifi
1. Hlola ngokubuka izintambo zikagesi, amakhebuli eribhoni angu-26P phakathi kwamayunithi amabhodi, nezibani zezinkomba zemojuli yamandla ukuze ubone ukuthi asebenza kahle yini.
2. Sebenzisa i-multimeter ukuze ulinganise ukuthi iyunithi yebhodi ine-voltage evamile, bese ukala ukuthi ukuphuma kwe-voltage yemoduli yamandla kujwayelekile.Uma kungenjalo, kwahlulelwa ukuthi imojuli yamandla inephutha.
3. Linganisa i-voltage ephansi yemojuli yamandla futhi ulungise ukulungiswa okuhle (eduze nokukhanya kwenkomba yemoduli yamandla) ukuze ufinyelele i-voltage evamile.
