Basa re coupler

1. Kuumbwa kwekuchinja kwedunhu

Kana iyo yekuisa chiratidzo ui yakaderera, iyo transistor V1 iri munzvimbo yakachekwa, ikozvino yechiedza-emitting diode muoptocoupler B1 inenge zero, uye kushorwa pakati peinobuda terminals Q11 neQ12 yakakura, iyo yakaenzana nekuchinja "kudzima";Kana ui yakakwira, v1 iripo, iyo LED muB1 iripo, uye kushorwa pakati peQ11 neQ12 kunoderedzwa, izvo zvakaenzana nekuchinja "pa".Dunhu iri mune yakakwira nhanho conduction mamiriro nekuti Ui yakaderera mwero uye switch haina kubatana.Saizvozvo, nekuti hapana chiratidzo (Ui yakaderera mwero), switch iripo, saka iri mune yakaderera level conduction state.

2. Kuumbwa kwe logic circuit

Dunhu iri UYE gedhi logic yedunhu.Chirevo chayo chine musoro ndechekuti P = AB Iwo maviri photosensitive chubhu mumufananidzo akabatana munhevedzano.Chete kana iyo yekuisa logic mazinga A=1 uye B=1, yakabuda P=1

3. Kuumbwa kweyega yekubatanidza dunhu

Iyo mutsara yekusimudzira mhedzisiro yedunhu inogona kuvimbiswa nekusarudza zvakanaka yazvino inomisa kuramba Rl yeinopenya dunhu uye kuita yazvino yekufambisa chiyero cheB4 kugara.

4. Gadzira high-voltage voltage stabilizing circuit

Iyo chubhu yekutyaira ichashandisa transistors ine high voltage inomira.Kana simba rekubuda richiwedzera, bias voltage yeV55 inowedzera, uye mberi ikozvino kwechiedza chinobudisa diode muB5 inowedzera, kuitira kuti inter-electrode voltage ye photosensitive tube inoderera, bias voltage yechubhu yakagadziridzwa kuva junction inoderera, uye kupikisa kwemukati kunowedzera, kuitira kuti magetsi ekubuda aderedze, uye kubuda kwemhepo kunoramba kwakagadzikana

5. Automatic control circuit yekuvhenekera kwehoro

A maseti mana eanalogi yemagetsi switch (S1 ~ S4): S1, S2 uye S3 zvakabatana zvakafanana (izvo zvinogona kuwedzera simba rekutyaira uye anti-kupindira kugona) yekunonoka dunhu.Pavanenge vachibatanidzwa kune magetsi, nzira mbiri thyristor VT inotungamirirwa neR4 neB6, uye VT inodzora zvakananga imba yekuvhenekera H;S4 uye yekunze photosensitive resistor Rl inoumba ambient light rekuona sedunhu.Kana musuwo wakavharwa, iyo inowanzovharwa tsanga KD yakaiswa pamusuwo wemusuwo inobatwa nemagneti pamusuwo, uye kubata kwayo kwakavhurika, S1, S2 uye S3 iri mune data yakavhurika mamiriro.Manheru, muridzi wemba akaenda kumba ndokuvhura musuo.Magneti aive kure neKD, uye yeKD contact yakavharwa.Panguva ino, magetsi e9V achabhadharwa kuC1 kuburikidza neR1, uye magetsi pamagumo ose eC1 achakurumidza kukwira ku9V.Iyo rectifier voltage ichaita kuti iyo LED muB6 ivheneke kuburikidza neS1, S2, S3 uye R4, nekudaro ichikonzeresa nzira mbiri thyristor kuti ibatike, VT ichabatidzawo, uye H ichabatidza, ichiziva otomatiki mwenje wekutonga basa.Mushure mekunge musuwo wavharwa, magineti anodzora KD, iyo yekubata inovhura, iyo 9V magetsi inomira kuchaja C1, uye dunhu rinopinda mukunonoka.C1 inotanga kuburitsa R3.Mushure menguva yekunonoka, magetsi kumativi ese eC1 zvishoma nezvishoma anodonha pasi pemhepo yekuvhura yeS1, S2 uye S3 (1.5v), uye S1, S2 uye S3 inotangazve kubviswa, zvichikonzera B6 cutoff, VT ​​cutoff, uye. H kupera, kuona kunonoka mwenje kudzima basa.
