I-Optocouplers, ezinxibe ieker ze-Optocouples ezisebenzisa imiqondiso ye-optical njengoko iphakathi, iyinto esebenzayo kwiindawo apho kuchanekile, njengeziko le-acousting, ngenxa yokuthengiswa kwabo, njengokuqina.
Kodwa sebenza nini kwaye phantsi kwaziphi iimeko apho umgaqo emva kwaso? Okanye xa usebenzisa ifotokopi kwifotokopi yakho ye-elektroniki, unokungazi ukuba uyikhetha njani kwaye uyisebenzise. Kuba i-Optocoupler ihlala ididekile nge "PhotoTransistor" kunye ne "Photodiode". Ke ngoko, yintoni ifotokopi iya kuqaliswa kweli nqaku.
Yintoni ifotokopi?
I-Optocoupler yicandelo le-elektroniki eline-Etymology engu-joylical
Isibini, esithetha ukuthi "ukudibanisa ukukhanya." Ngamanye amaxesha kwakhona ikwabizwa ngokuba yi-Optocoupler, i-SOPOCATOR SOITOOTOR, i-insullical yokufakelwa, njl njl. Akukho nxibelelwano lombane phakathi kwele sesekethe, ngamanye amagama, kwimeko yokufakelwa. Ke ngoko, ukudityaniswa kwesekethe phakathi kwegalelo kunye negalelo kwahlukile kwaye kuphela umqondiso udluliselwa. Iisekethe eziqinisekileyo zokhulisa ngokukhuselekileyo ngegalelo elahlukileyo legalelo kunye ne-Vinetiment Vienege, kunye ne-Inteltage yeVoltage phakathi kwegalelo kunye nemveliso.
Ukongeza, ngokuhambisa okanye ukuvimba olu phawu lokukhanya, lusebenza njengesitshisi. Umgaqo-siseko oneenkcukacha kunye nendlela uya kuchazwa kamva, kodwa ukukhanya kwegama lokufotcopeupler yi-LED (ekukhanyiseni i-Diode).
Ukususela ngo-1960 ukuya kuthi ga kwiminyaka yoo-1970, xa i-LED yayothuswa kunye nenkqubela phambili yezobuchwephesha yayibalulekile,i-optoelectronicsyaba yinto eyomnyama. Ngelo xesha, ezahlukeneyoIzixhobo ze-Opticalzangelwe, kwaye i-piclectric inye yazo. Emva koko, i-optoelectrosics ingene ngokukhawuleza ebomini bethu.
Umgaqo / umatshini
Umgaqo we-Optocoupler kukuba into ekhuphayo ikhuphe uphawu lwegalelo lokungena endaweni yokukhanya, kwaye into eyamkelayo yokukhanya idlulisela umqondiso wombane wendlela yokuphuma. Inqaku lokukhanya lokukhanya kunye nenqaku elifumana ukukhanya liphakathi kwebhloko yokukhanya yangaphandle, kwaye zombini ziyahlukanana ukuze zidlulisele ukukhanya.
I-semicondtuctorctor esetyenziselwa izinto zokukhupha ukukhanya yi-LED (i-diode yokukhuphela). Kwelinye icala, zininzi iindidi ze-semiorunder ezisetyenziswa kwizixhobo zokufumana ukukhanya, kuxhomekeka kwindawo yokusetyenziswa, ubungakanani bangaphandle, ixabiso, njl njl.
Xa bengasebenzi, iifoto zefoto zithwele kancinci ukuba i-semicondors yenziwa. Xa ukukhanya kwesehlo apho, imifanekiso yefoto ivelisa amandla amanqam kwi-P-Chwether ye-P-Chwether kunye nohlobo lwe-semiconductor, i-Elemicon Semiconductor, i-Elemicon Semiconductor, i-Elecacondtucorthector kwingingqi ye-PMORD ingena kwingingqi, kwaye okwangoku iya kuhamba.
Iifoto zefoto aziphendulanga njengeefoto, kodwa zinefuthe lokuphucula iziphumo kumakhulu ukuya kwi-1 000 i-sundel yendawo yombane yangaphakathi). Ke ngoko, banolwazelelelo ngokwaneleyo ukuba bathathe imiqondiso ebuthathaka, eyinzuzo.
Ngapha koko, "I-Blocker yokukhanya" esiyibona sisixhobo se-elektroniki esinemigaqo efanayo kunye nendlela.
Nangona kunjalo, ukuphazamiseka okukhanyayo kuhlala kusetyenziswa njengoko izinzwa kwaye zenze indima yazo ngokudlulisela into yokukhanya ephakathi kwento ekuthoba ukukhanya kunye nento enokufumana ukukhanya. Umzekelo, inokusetyenziselwa ukufumana iingqekembe kunye neebhanki kuomatshini abathengisa oomatshini kunye nee-ATM.
② Iimpawu
Kuba i-Optocoupler iguqula imiqondiso yokukhanya, ukufakwa phakathi kwecala lokufaka kunye necala lokuphuma yinto ephambili. Ukufakelwa okuphezulu akuchaphazelekanga ngokulula ngengxolo, kodwa kukuthintele ukuhamba ngengozi phakathi kwesekethe ekufuphi, esebenza kakhulu ngokweyokhuseleko. Kwaye isakhiwo ngokwayo silula kwaye sisengqiqweni.
Ngenxa yembali yayo ende, Imveliso etyebileyo yemveliso yabavelisi abahlukeneyo ikwangento ekhethekileyo ye -ptocouplers. Kuba akukho nxibelelwano lomzimba, ukunxiba phakathi kwamalungu amancinci, kwaye ubomi bude. Kwelinye icala, kukho iimpawu ezinobuchule obukhoyo obulula kakhulu, kuba i-LED iya kuthi ihluze kancinci ngokudlula kwexesha kunye notshintsho lobushushu.
Ingakumbi xa icandelo langaphakathi leplasitiki elibonakalayo ixesha elide, libe lifu, alinakukhanya. Nangona kunjalo, nangayiphi na imeko, ubomi bude xa kuthelekiswa nomfowunelwa woqhakamshelwano ngonxibelelwano lwendlela.
Iifoto zefoto zihlala zicotha kuneefoto ze-foto, ke azisetyenziselwa unxibelelwano oluphezulu. Nangona kunjalo, le ayisiyongxaki, njengoko ezinye izinto zinesekethe zokuziqhelanisa kwicala lokuphuma ukuze kunyuswe isantya. Ngapha koko, ayizizo zonke ixhoba le-elektroniki ezifuna ukonyusa isantya.
Ukusetyenziswa
Abatshati beefotoisetyenziselwa ikakhulu ukutshintsha umsebenzi. Isekethe iya kunikezelwa ngokuguqula iswitshi, kodwa ukusuka kwindawo yokujonga kwezi mpawu zingasentla, ngakumbi i-internarios efuna ukuthembeka okukhulu. Umzekelo, ingxolo lutshaba lwee-elektroniki ze-elektroniki kunye nezixhobo zeaudiyo / izixhobo zonxibelelwano.
Ikwasetyenziswa nakwinkqubo yokuqhuba iimoto. Isizathu semoto kukuba isantya silawulwa yi-inverter xa iqhutywa, kodwa ivelisa ingxolo ngenxa yemveliso ephezulu. Le ngxolo ayiyi kubangela kuphela izithuthi ukuba ziphumelelise, kodwa iphinde ihambe "kumhlaba" echaphazela i-PAPhelos. Ngokukodwa, izixhobo ezinobuqhetseba omde zilula ukukhetha le ngxolo iphambili, ke ukuba yenzeka kumzi-mveliso, iya kubangela ilahleko enkulu kwaye ngamanye amaxesha ibangela ingozi enkulu. Ngokusebenzisa i-optocouperple ye-optocle eqhoshwe kakhulu yokutshintsha, ifuthe kwezinye iithekethi kunye nezixhobo zinokuncitshiswa.
Okwesibini, indlela yokukhetha kwaye isebenzise i-optocouplers
Ungayisebenzisa njani i-Optocoupipler yasekunene yesicelo kwimveliso yemveliso? Ezi zonjineli zophuhliso zilandelayo ze-microcontrolir ziya kuchaza indlela yokukhetha nokusebenzisa i-optocouplers.
① Hlala uvulekile kwaye uhlala uvale
Zimbini iintlobo zeefotokopi: uhlobo apho utshintsho lucinyiwe (ngaphandle) xa kusetyenziswa i-voltage, uhlobo apho i-switch ifakwe khona, kwaye udidi apho kungekho votige. Faka isicelo kwaye ucime xa kusetyenziswa i-voltage.
Okwangaphambili ibizwa ngokuba ivulekile, kwaye oku kubizwa ngokuba kuvaliwe. Ungawukhetha njani, okokuqala kuxhomekeke kuhlobo lwesekelo olufunayo.
Jonga iMeko yemveliso yangoku kwaye isetyenzisiwe i-voltage
Iifotokopi zinepropathi yokwazisa umqondiso, kodwa awusoloko udlula kwi-voltage nangoku. Ewe kunjalo, kuyaliwe, kodwa i-voltage kufuneka isetyenziswe kwicala lokufaka ngokwakho.
Ukuba sijonga iphepha ledatha yemveliso, sinokubona itshathi apho i-axis ethe tyaba ivele (umqokeleli yangoku) kunye ne-axis ethe tyaba yi-Axis i-intertage (i-voltage ye-Voltitter). Umqokeleli ophakathi uyahluka ngokwamandla okukhanya okukhoyo, ngenxa yoko sebenzisa i-voltage ngokwemveliso efunekayo okwangoku.
Nangona kunjalo, unokucinga ukuba iziphumo ezikhoyo zibaliwe apha zincinci kakhulu. Eli lixabiso langoku elinokubakho ukuvelisa ngokuthembekileyo emva kokuthathela ingqalelo ukuwohloka kwe-kukhutshelwe i-LED ngokuhamba kwexesha, ngoko kungaphantsi komgangatho ophezulu.
Ngokuchasene noko, kukho iimeko apho iziphumo zangoku azikho zinkulu. Ke ngoko, xa ukhetha i-Optocoupler, qiniseka ukuba ujonga ngocoselelo i "Imveliso yangoku" kwaye ukhethe imveliso ehambelana nayo.
③ Ekuphezulu okwangoku
Olona xesha luphezulu lwangoku lelona xabiso liphezulu elinokuhlala linokuqhuba. Kwakhona, kufuneka siqiniseke ukuba siyayazi ukuba ingaba ingakanani iprojeki kwaye ithini i-inftage yegalelo ngaphambi kokuba sithenge. Qiniseka ukuba elixabiso liphezulu kunye nelisetyenzisiweyo elisetyenzisiweyo alikho mida, kodwa ke kukho umda.
Cwangcisa ifotokopi ngokuchanekileyo
Ukunyula i-Optocouple yasekunene, masiyisebenzise kwiprojekthi yokwenyani. Ufakelo ngokwalo lulula, dibanisa i-terminals exhunyiwe kwisekethe nganye yesekethe kunye nesekethe esecaleni esecaleni. Nangona kunjalo, ukhathalelo kufuneka luthathwe ukuba ungasebenzisi ncam kwicala lokufaka kunye necala lokuphuma. Ke ngoko, kuya kufuneka ujonge iisimboli kwitafile yedatha, ukuze ungafumani ukuba unyawo lwefotwili alulunganga emva kokutsala iBhodi yePCB.
