Aiki na coupler

1. Haɗin kai na kewayawa

Lokacin da siginar shigarwar ui ya yi ƙasa, transistor V1 yana cikin yanayin yankewa, halin yanzu na diode mai fitar da haske a cikin optocoupler B1 kusan sifili ne, kuma juriya tsakanin tashoshin fitarwa Q11 da Q12 yana da girma, wanda shine. daidai da maɓallin "kashe";Lokacin da ui ya kasance babban matakin, v1 yana kunne, LED a B1 yana kunne, kuma an rage juriya tsakanin Q11 da Q12, wanda yayi daidai da kunna "kunna".Da'irar tana cikin babban matakin gudanarwa saboda Ui ƙananan matakin kuma ba a haɗa mai kunnawa ba.Hakazalika, saboda babu sigina (Ui low matakin), mai kunnawa yana kunne, don haka yana cikin yanayin gudanarwa mara nauyi.

2. Abun da ke tattare da tsarin dabaru

Da'irar ita ce da'irar dabaru na ƙofar AND.Maganar ma'anarta ita ce P=AB An haɗa bututun masu ɗaukar hoto guda biyu a cikin adadi a jere.Sai kawai lokacin shigar dabaru matakan A=1 da B=1, fitarwa P=1

3. Haɗin haɗin keɓaɓɓen da'ira

Za'a iya ba da garantin tasirin ƙara girman layin da'irar ta hanyar zaɓar daidaitaccen juriya na ƙayyadaddun juriya na yanzu na kewaye mai haske da kuma sanya rabon watsawa na yanzu na B4 akai akai.

4. Ƙirƙirar da'irar ƙarfafa ƙarfin lantarki mai ƙarfi

Bututun tuƙi zai yi amfani da transistor tare da juriya mai ƙarfi.Lokacin da ƙarfin fitarwa ya karu, ƙarfin wutar lantarki na V55 yana ƙaruwa, kuma ƙarfin halin yanzu na diode mai haske a cikin B5 yana ƙaruwa, don haka ƙarfin lantarki na inter-electrode na bututun hotuna ya ragu, ƙarancin ƙarfin lantarki na bututun daidaitacce yana raguwa, kuma juriya na ciki yana ƙaruwa, don haka ƙarfin wutar lantarki ya ragu, kuma ƙarfin fitarwa ya kasance barga

5. atomatik kula da kewaye na hall lighting

A shine nau'i hudu na maɓallan lantarki na analog (S1 ~ S4): S1, S2 da S3 suna haɗe a layi daya (wanda zai iya ƙara ƙarfin tuƙi da ikon tsangwama) don jinkirin jinkiri.Lokacin da aka haɗa su da wutar lantarki, hanyar Thyristor VT ta hanyar R4 da B6 ne ke tafiyar da su, kuma VT kai tsaye yana sarrafa hasken zauren H;S4 da resistor photosensitive na waje Rl sun zama da'irar gano haske na yanayi.Lokacin da aka rufe ƙofar, KD ɗin da aka saba rufewa a kan firam ɗin ƙofar yana shafar magnet ɗin da ke ƙofar, kuma lambar sadarwarsa a buɗe take, S1, S2 da S3 suna cikin yanayin buɗe bayanai.Da yamma mai gida ya koma gida ya bude kofa.Magnet ɗin ya yi nesa da KD, kuma an rufe lambar sadarwar KD.A wannan lokacin, za a yi cajin wutar lantarki na 9V zuwa C1 ta hanyar R1, kuma ƙarfin lantarki a duka ƙarshen C1 zai tashi zuwa 9V.Wutar lantarki mai daidaitawa zai sa LED a cikin B6 ya haskaka ta hanyar S1, S2, S3 da R4, don haka kunna thyristor ta hanyoyi biyu don kunna, VT kuma zai kunna, kuma H zai kunna, yana fahimtar aikin sarrafa hasken wuta ta atomatik.Bayan an rufe ƙofar, magnet yana sarrafa KD, lambar sadarwa ta buɗe, wutar lantarki ta 9V ta dakatar da cajin C1, kuma kewayawa ya shiga yanayin jinkiri.C1 ya fara fitarwa R3.Bayan wani lokaci na jinkiri, ƙarfin lantarki a duka ƙarshen C1 a hankali yana faɗuwa ƙasa da buɗe wutar lantarki na S1, S2 da S3 (1.5v), da S1, S2 da S3 suna ci gaba da katsewa, wanda ya haifar da yankewar B6, yanke VT, da H bacewa, sanin jinkirin aikin kashe fitilar.
