Umsebenzi we-coupler

1. Ukwakheka kwesekethe yokushintsha

Uma isignali ye-ui yokufaka iphansi, i-transistor V1 isesimweni sokunqanyulwa, amandla amanje e-diode ekhipha ukukhanya ku-optocoupler B1 cishe i-zero, futhi ukumelana phakathi kwamatheminali okukhiphayo i-Q11 ne-Q12 kukhulu, okuyi- okulingana noshintsho "cima";Uma i-ui isezingeni eliphezulu, i-v1 ivuliwe, i-LED ku-B1 ivuliwe, futhi ukumelana phakathi kwe-Q11 ne-Q12 kuyancishiswa, okulingana nokushintshwa "kuvuliwe".Isekhethi isesimweni sokwenziwa kwezinga eliphezulu ngenxa yokuthi i-Ui isezingeni eliphansi futhi iswishi ayixhunyiwe.Ngokufanayo, ngenxa yokuthi asikho isignali (i-Ui iyizinga eliphansi), inkinobho ivuliwe, ngakho-ke isesimweni sokwenza izinga eliphansi.

2. Ukwakheka kwesekethe ye-logic

Isekhethi iyisekhethi ye-logic yesango KANYE.Inkulumo yayo enengqondo ithi P=AB Amashubhu amabili azwelayo esithombeni axhunywe ochungechungeni.Kuphela uma amazinga okokufaka anengqondo A=1 kanye no-B=1, okukhiphayo P=1

3. Ukwakhiwa kwesekethe yokuhlanganisa eyodwa

Umphumela wokukhulisa umugqa wesekethe ungaqinisekiswa ngokukhetha kahle ukumelana nomkhawulo wamanje we-Rl wesekethe ekhanyayo nokwenza isilinganiso samanje sokudlulisa se-B4 sibe njalo.

4. Yakha isekethe yokusimamisa kagesi wamandla kagesi aphezulu

Ishubhu lokushayela kufanele lisebenzise ama-transistors ane-voltage ephezulu ukumelana.Lapho i-voltage ephumayo ikhuphuka, i-voltage yokuchema ye-V55 iyanda, futhi amandla ahamba phambili e-diode ekhipha ukukhanya ku-B5 ayanda, ukuze i-voltage ye-inter-electrode yeshubhu ye-photosensitive yehle, i-voltage yokuchema ye-tube elungisiwe ibe ukuhlangana iyancipha, futhi ukumelana kwangaphakathi kuyanda, ukuze i-voltage yokuphuma iyancipha, futhi i-voltage yokuphuma ihlala izinzile

5. Isifunda sokulawula okuzenzakalelayo sokukhanyisa kwehholo

A amasethi amane okushintsha kwe-electronic analog (S1~S4): I-S1, i-S2 ne-S3 zixhunywe ngokuhambisana (okungakhuphula amandla okushayela nekhono lokulwa nokuphazamiseka) kumjikelezo wokulibaziseka.Uma zixhunywe kugesi, i-thyristor VT yezindlela ezimbili iqhutshwa yi-R4 ne-B6, futhi i-VT ilawula ngokuqondile ukukhanya kwehholo H;I-S4 kanye ne-photosensitive resistor Rl yangaphandle bakha isekethe yokuthola ukukhanya okuzungezile.Lapho umnyango uvaliwe, i-KD evalekile yomhlanga efakwe kuhlaka lomnyango ithintwa uzibuthe emnyango, futhi ukuthintana kwayo kuvuliwe, i-S1, i-S2 ne-S3 isesimweni sokuvula idatha.Kusihlwa, umninikhaya waya ekhaya futhi wavula umnyango.Umazibuthe ubekude ne-KD, futhi oxhumana naye we-KD uvaliwe.Ngalesi sikhathi, ugesi we-9V uzoshajwa ku-C1 ukuya ku-R1, futhi ugesi emikhawulweni yomibili ye-C1 uzokhuphukela ku-9V maduze.I-voltage yokubuyisela izokwenza i-LED eku-B6 ikhanye nge-S1, S2, S3 kanye ne-R4, ngaleyo ndlela icuphe i-thyristor enezindlela ezimbili ukuthi ivule, i-VT izophinda ivule, futhi i-H izovula, ibone umsebenzi wokulawula ukukhanya okuzenzakalelayo.Ngemva kokuvalwa komnyango, uzibuthe ulawula i-KD, othintana naye uyavula, ukunikezwa kwamandla kwe-9V kuyeka ukushaja i-C1, futhi isifunda singena esimweni sokulibala.I-C1 iqala ukukhipha u-R3.Ngemva kwesikhathi sokulibaziseka, i-voltage emikhawulweni yomibili ye-C1 yehla kancane kancane ngaphansi kwamandla kagesi wokuvula we-S1, S2 kanye ne-S3 (1.5v), futhi i-S1, i-S2 ne-S3 iqala kabusha ukuze inqanyulwe, okuholela ekunqanyulweni kwe-B6, ukunqamuka kwe-VT, kanye H ukushabalala, ukubona umsebenzi wokucisha isibani ulibazisekile.
