Menene dalilin gazawar lodi ko sadarwa?

Dalilan da suka sa gazawar sadarwa da lodawa kusan iri daya ne, wanda wasu dalilai ne ke iya haifar dasu. Da fatan za a kwatanta tare da aiki bisa ga dalilan da aka lissafa:

1. Tabbatar cewa ana kunna kayan aikin tsarin sarrafawa da kyau. (+ 5 v)

2. Bincika kuma tabbatar cewa layin serial da akayi amfani da shi don haɗa mai sarrafa layi ne madaidaiciya, kuma ba layin tsallaka bane ba.

3. Bincika kuma tabbatar cewa layin haɗin serial ɗin yana nan lafiyayye kuma babu sassautawa ko faɗuwa a ƙarshen duka biyun.

4, daAllon LEDsarrafa software da zaɓin katin sarrafawa don zaɓar samfurin samfuran daidai, yanayin watsawa daidai, madaidaicin lambar tashar tashar, madaidaicin saurin watsawa da kuma software da aka bayar ta hanyar zane mai bugun kira don saita madaidaicin tsarin tsarin sarrafawa akan adireshin kashi da serial watsa kudi.

5. Bincika ko tsalle tsalle yana kwance ko a kashe; Idan jumper cap din ba a kwance yake ba, ka tabbata tsumman yana kan hanya madaidaiciya.

6. Idan lodin ya kasa har yanzu bayan binciken da aka yi a sama da gyara, da fatan za a yi amfani da multimeter don auna ko serial port din da ke hade da kwamfutar ko kuma kayan aikin tsarin sarrafawa sun lalace don tabbatar da cewa ya kamata a mayar da shi ga mai kera kwamfutar ko kayan aikin tsarin sarrafawa don gwaji.

Allon LED common fault solutions

Two, the Allon LED just on the power when a few seconds of bright line or screen picture changed flowers?

Bayan an haɗa mai kula da allon sosai da kwamfutar, hukumar rarraba HUB da allon, ya zama dole a samar da wutar lantarki + 5V ga mai kula don yin aiki daidai (a wannan lokacin, kar a haɗa kai tsaye zuwa ƙarfin 220V) .

A lokacin da wuta ke kunne, layi mai haske ko "allo na fantsama" zai bayyana akan allo na wasu secondsan daƙiƙoƙi, waɗanda al'amuran gwaji ne na yau da kullun kuma suna tunatar da mai amfani cewa allon yana gab da fara aiki kwata-kwata. Tsakanin sakan 2, lamarin an cire ta atomatik, allon cikin yanayin aiki na yau da kullun.

Uku, Menene ma'anar daidaitawar haske ta atomatik ko ta hannu?

Daidaita haske yana nufin daidaitawa tsakanin mafi haske da haske allon zai iya nunawa, ba daidaita ƙararrawa ba. Gyara haske na atomatik ya dogara da haske daban-daban ya kamata ya bayyana a cikin lokaci daban-daban kuma ya cikaAllon LEDTsarin sarrafawa ta atomatik daidaita zuwa takamaiman haske wanda aka ƙaddara.Matsalar haske ta hannu yana nufin aiki naAllon LED control system by the end user to make the Allon LED reach a certain specified brightness.

Hudu, allon naúrar ya bayyana duk allon ba haske, mai duhu

1. Duba da kyau ko kebul na 26P tsakanin kebul ɗin wuta da allon naúrar da hasken mai nuna ƙirar wutar lantarki al'ada ce.

2. Yi amfani da multimeter don aunawa ko allon naúrar tana da ƙarfin lantarki na yau da kullun, sannan auna ko ƙarfin fitarwa na wutar lantarki yana da kyau. Idan ba haka ba, ana yanke hukunci cewa powerarfin wutar ya lalace.

3. Gwaji ƙarfin wutan lantarki na wutar lantarki kuma daidaita shi daidai (gyaran wuta na wutar lantarki kusa da hasken mai nuna alama) don yin ƙarfin lantarki ya daidaita.

Five, what is the reason why the Allon LED appears all black?

A yayin aiwatar da amfani da tsarin sarrafawa, lokaci-lokaci zamu hadu da abin mamaki wandaAllon LEDduk baki ne.Wannan lamari na iya faruwa ta wasu dalilai daban-daban, har ma tsarin duhun allo na iya bambanta daga aiki zuwa aiki ko daga yanayi zuwa muhalli.

Misali, yana iya zama baƙi da zaran ya kunna, zai iya zama baƙi yayin lodawa, yana iya zama baƙi bayan aikawa, da sauransu:

1. Da fatan za a tabbatar cewa duk kayan aiki, gami da tsarin sarrafawa, suna da ƙarfin aiki. (+ 5V, kar a juya haɗi, haɗi mara kyau)

2. Duba kuma sake tabbatarwa ko layin sadarwar da aka yi amfani da shi don haɗa mai sarrafa ya kwance ko ya faɗi. (Idan ya yi baƙi lokacin lodawa, mai yiwuwa wannan ne ya haifar da shi, wato, layin sadarwa ya kwance kuma ya katse yayin hanyar sadarwa, saboda haka allo ya zama baƙi. Kar kuyi tunanin jikin allo ba ya motsi, kuma layin ba zai iya kwance ba. Da fatan za a fara dubawa, wanda ke da matukar muhimmanci don magance matsalar cikin sauri.)

3. Bincika kuma tabbatar ko hukumar rarraba HUB ta haɗu daAllon LEDkuma babban buga katin kasuwancin kasuwanci an haɗa shi sosai kuma an shigar dashi.
