Mosebetsi oa coupler

1. Sebopeho sa potoloho ea phetoho

Ha lets'oao la ho kenya ui le le tlase, transistor V1 e sebakeng se khaotsoeng, hona joale ha khanya e ntšang leseli ho optocoupler B1 e batla e le zero, 'me khanyetso pakeng tsa li-terminals tsa Q11 le Q12 e kholo, e lekanang le switjha "tima";Ha ui e le boemong bo phahameng, v1 e butsoe, LED ka B1 e ntse e le teng, 'me khanyetso pakeng tsa Q11 le Q12 e fokotsehile, e lekanang le ho fetola "ho".Potoloho e boemong bo phahameng ba conduction hobane Ui e tlase mme switch ha e kopane.Ka mokhoa o ts'oanang, hobane ha ho na lets'oao (Ui ke boemo bo tlase), switch e butsoitse, kahoo e maemong a tlase a conduction.

2. Sebopeho sa potoloho ea logic

Potoloho ke LE heke logic potoloho.Polelo ea eona ea kelello ke P=AB Li-tubes tse peli tse etsang lifoto setšoantšong li hokahane ka letoto.Ke feela ha maemo a logic a kenyang A=1 le B=1, tlhahiso P=1

3. Sebopeho sa potoloho e kopanetsoeng e arohaneng

Matla a ho holisa moeli oa potoloho a ka netefatsoa ka ho khetha ka nepo Rl e fokotsang moeli oa potoloho e khanyang le ho etsa hore karolelano ea phetisetso ea B4 e be teng kamehla.

4. Theha potoloho e tsitsitseng ea matla a matla a motlakase

Thepa ea ho khanna e tla sebelisa li-transistors tse nang le matla a phahameng a ho mamella.Ha motlakase oa tlhahiso o ntse o eketseha, motlakase oa leeme oa V55 oa eketseha, 'me lebelo la pele la khanya e tsoang ho B5 lea eketseha, e le hore motlakase oa inter-electrode oa tube ea photosensitive o fokotsehe, matla a leeme a tube e fetotsoeng e fokotseha, 'me ho hanyetsa ka hare hoa eketseha, e le hore motlakase oa lihlahisoa o fokotsehe,' me motlakase oa lihlahisoa o lule o tsitsitse

5. Potoloho ea taolo e ikemetseng ea mabone a holo

A ke lihlopha tse 'nè tsa li-switch electronics tsa analog (S1 ~ S4): S1, S2 le S3 li kopantsoe ka tsela e tšoanang (e ka eketsang matla a ho khanna le bokhoni ba ho thibela ho kena-kenana) bakeng sa potoloho ea ho lieha.Ha li kopantsoe le motlakase, thyristor VT ea litsela tse peli e tsamaisoa ke R4 le B6, 'me VT e laola ka ho toba holo e khanyang H;S4 le Rl ea kantle ea photosensitive resistor li etsa potoloho ea ho bona leseli.Ha lemati le koetsoe, lehlaka le tloaelehileng le koetsoeng la KD le kentsoeng monyakong oa monyako le angoa ke makenete monyako, 'me puisano ea eona e bulehile, S1, S2 le S3 li boemong bo bulehileng ba data.Mantsiboea, mong’a ntlo o ile a ea hae ’me a bula monyako.Makenete o ne o le hole le KD, mme lebitso la KD le ne le koetsoe.Ka nako ena, motlakase oa 9V o tla lefisoa ho C1 ho ea ho R1, 'me matla a mahlakoreng ka bobeli a C1 a tla tloha a nyolohela ho 9V.Motlakase oa rectifier o tla etsa hore LED e B6 e khanye ka S1, S2, S3 le R4, kahoo e etsa hore thyristor ea litsela tse peli e bulehe, VT e tla boela e bule, 'me H e tla buleha, e hlokomele mosebetsi oa ho laola mabone o itekanetseng.Ka mor'a hore lemati le koetsoe, makenete e laola KD, puisano e bula, motlakase oa 9V o emisa ho tjhaja C1, 'me potoloho e kena boemong ba ho lieha.C1 e qala ho ntša R3.Ka mor'a nako ea tieho, motlakase lipheletsong tse peli tsa C1 butle-butle o theoha ka tlase ho matla a ho bula a S1, S2 le S3 (1.5v), 'me S1, S2 le S3 li qala hape ho khaoha, ho fella ka hore B6 cutoff, VT ​​cutoff, le. H ho fela, ho hlokomela hore lebone le liehile ho tima ts'ebetso.
