Kule adhodysey ethokozisayo yokutholwa, sizogxila ezweni eliyinkimbinkimbi lama-opococouplers, ngokugxila okuthile ebudlelwaneni obuphakathi kwe-LEDS ne-NPN-Type PhotoTransistors.Ngaphezu kwalokho, le nkulumo izokuvela kahle ama-nuances of analog ukwahlukanisa ama-amplifiers futhi antanta imithombo yamanje, izinkundla ezibonakalayo ze-OptoCoupler Technology.
Npn transporor optocoupler
I-OptoCoupler, noma i-Opto-i-Isolator, ivela njengengxenye ye-elektroniki ye-quintessential.Idlulisela amasiginali kagesi ngokuziguqula abe amasiginali we-optical, athi anciphise isithiyo sokuhlukaniswa ngogesi, eqinisekisa uhambo oluphephile kusuka kokungenayo kokukhipha.Idizayinelwe njenge-STALWART Sentinel, le divayisi ivikela izingxenye zesifunda kusuka ekuhlaselweni kwamandla ama-voltages aphezulu noma okungazelelwe, kuqinisekisa ukuthembeka kokudluliselwa kwesiginali.Ukuqhafaza umthamo wokumelana nokufaka nokukhipha ama-voltages esikalini sezinkanyezi, ama-opocoupler wezentengiselwano asolaphi lapho ephatha izinguquko ezisheshayo ze-voltage.Imvamisa, i-terminus eyodwa yale divayisi ihlanganisa i-LED ye-infrared ukuqala ukuhambisa, ngenkathi umlingani wayo, i-PhotoDetor efana ne-Photodiode noma i-PhotoTransistor, ilindele kwisithiyo sokuzihlukanisa ukuze iliphele.E-Quiecence, ama-transistor amanga athule;Kodwa-ke, njengoba i-LED ikhipha i-beacon yayo ekhanyayo, umfudlana we-PhotoCoprent ubizelwe esisekelweni sakwaTranster, wawuvusa esenzweni.
Yakha Umhlahlandlela
Ukuqala lo msebenzi wokuhlola kudinga umhlangano we-OptoCoupler.I-LED ye-infrared ne-NPN PhotoTransistor evela kwi-ADALP2000 Analog Parp Phic izingxenye zinconyelwe ukuvumelanisa kwabo okufakazelwe.Ukuqala ngokubumba izikhonkwane eziholwa yi-LED ne-transistor ku-angle engu-90 °, kuqinisekiswe ukuthi zivumelanisa futhi zilondoloze ukukhuphuka okungaguquki ku-selderless Blowboard.Ukwandisa ukunemba nokuphindaphinda kwemizamo yakho yokuhlola, kuhlakaniphile uku-ethsholo ama-LEDs kanye nama-transtoristors anetheyiphu emnyama efakwayo, ngaleyo ndlela anciphise ukungenela ukukhanya kokukhanya.
Izilungiselelo ze-Hardware Nezilungiselelo
Ukuqhubekela phambili ekuhlolweni, ukucushwa okuthile kwehardware kanye nezindlela zenqubo ze-Beckolon.Lungiselela i-WaveForm Generator ukucacisa i-waveform ethile, bese uhlanganyela neziteshi ezimbili ze-Oscilloscope ukuze uhlolisise futhi unciphise ukuziphatha komjikelezo.Lokhu kuphawula okunamandla kukunikeze amandla okunciphisa isilinganiso samanje sokudlulisela, okunikeza imininingwane ngokusebenza kwe-OptoCoupler.Ukushintshana phakathi kwama-waveforms ahlukahlukene kanye nezilinganiso ezihambelana namandla wokuphendula kanye ne-alacrity ye-OptoCoupler.
Ngokuqhubeka kokuthuthuka kwelebhu, uzohamba ngokubukwa kusuka ekwakheni ama-opocopler e-opocopler ukuze uwasebenzise ekwakhiweni kwama-amplifiers we-analog solate aqothuliwe.Isigaba ngasinye siyi-foray ebanzi kwimigomo yobunjiniyela bakagesi.Ubuningi bama-wavenforms kanye nama-frequencys ahlaziya ahlelela ukuqonda okujulile kwamakhono we-optocoupler namandla ezicelo ezibonakalayo.
Sengiphetha, okuthi inzalo ekucushweni okuhlukahlukene kwesifunda kanye nezindlela zokulinganisa zembula ukuguquguquka okuhlukahlukene kanye nokuqina kobuchwepheshe be-Optoboupler.Noma ngabe kusetshenziswe izindawo zezimboni noma izindlela zokufunda, ama-Opotocouplers ame njengezinsimbi ezibalulekile zokuhlukaniswa nokudluliselwa kwesiginali.Ukuholwa okunikezwe lapha akukugcini nje ngamakhono wokwakha nokusebenzisa ama-opococoplers;Ibuye ifake nokuqonda okujulile kokubaluleka kwazo nokusebenza kwazo e-Vanguldi yezobuchwepheshe banamuhla kagesi.
