1. Ukuqulunqwa kwesiphaluka sokutshintsha
Xa i-ui yegalelo ye-ui iphantsi, i-transistor V1 ikwimeko yokunqunyulwa, i-current ye-diode ekhupha ukukhanya kwi-optocoupler B1 iphantse i-zero, kwaye ukuchasana phakathi kwee-terminals ze-Q11 kunye ne-Q12 kukhulu, okuyiyo. ilingana nokucima "ukucima";Xa i-ui ikwinqanaba eliphezulu, i-v1 ivuliwe, i-LED kwi-B1 ivuliwe, kwaye ukuchasana phakathi kwe-Q11 kunye ne-Q12 kuncitshisiwe, okulingana nokutshintsha "kwi".Isekethe ikwinqanaba eliphezulu lokuqhuba kuba i-Ui ikwinqanaba eliphantsi kwaye iswitshi ayidityaniswanga.Ngokufanayo, ngenxa yokuba akukho mqondiso (i-Ui ikwinqanaba eliphantsi), iswitshi ivuliwe, ngoko ikwinqanaba eliphantsi lokuqhuba.
2. Ukuqulunqwa kwesekethe ye-logic
Isekethe yi- AND gate logic circuit.Intetha yayo yengqiqo ithi P=AB Iityhubhu ezimbini zefotosensitive emfanekisweni ziqhagamshelwe kuthotho.Kuphela xa amanqanaba engqiqo yegalelo A=1 kunye ne-B=1, imveliso P=1
3. Ukuqulunqwa kweesekethe zokudibanisa ezizimeleyo
Isiphumo sokukhulisa umgca wesekethe sinokuqinisekiswa ngokukhetha ngokufanelekileyo ukuchasana nokukhawulelana kwangoku kwe-Rl yesiphaluka esikhanyayo kunye nokwenza umlinganiselo wangoku wokuhanjiswa kwe-B4 rhoqo.
4. Qamba i-high-voltage voltage stabilizing circuit
Umbhobho wokuqhuba uya kusebenzisa ii-transistors ezinevoltheji ephezulu yokumelana.Xa i-voltage ephumayo inyuka, i-voltage ye-bias ye-V55 iyanda, kwaye umsinga wangaphambili we-diode ekhupha ukukhanya kwi-B5 iyanda, ukuze i-voltage ye-electrode ye-photosensitive tube iyancipha, i-voltage ye-bias ye-tube ehlengahlengisiweyo ibe yi-junction iyancipha, kunye nokuchasana kwangaphakathi kwanda, ukwenzela ukuba i-voltage ephumayo iyancipha, kwaye i-voltage ye-output ihlale iqinile
5. Isiphaluka solawulo oluzenzekelayo lokukhanyisa iholo
A iiseti ezine ze-analog electronic switches (S1 ~ S4): I-S1, i-S2 kunye ne-S3 zixhunyiwe ngokufanayo (ezinokunyusa amandla okuqhuba kunye nokukwazi ukuchasana nokuphazamiseka) kwisiphaluka sokulibaziseka.Xa zidibene nombane, i-thyristor ye-VT yeendlela ezimbini iqhutywe yi-R4 kunye ne-B6, kwaye i-VT ilawula ngokuthe ngqo ukukhanya kweholo H;I-S4 kunye ne-Rl ye-photosensitive resistor yangaphandle zenza i-ambient light yesekethe.Xa ucango luvaliwe, i-KD yengcongolo eqhelekileyo efakwe kwisakhelo socango ichaphazeleka yimagnethi emnyango, kwaye unxibelelwano lwayo luvulekile, i-S1, i-S2 kunye ne-S3 zikwimeko evulekileyo yedatha.Ngokuhlwa, umamkeli-ndwendwe wagoduka waza wavula ucango.Umazibuthe wayekude ne KD, kwaye uqhagamshelwano lwe KD lwavalwa.Ngeli xesha, umbane we-9V uya kuhlawuliswa kwi-C1 nge-R1, kwaye i-voltage kuzo zombini iziphelo zeC1 iya kunyuka ngokukhawuleza kwi-9V.I-voltage ye-rectifier iya kwenza i-LED kwi-B6 ikhanyise nge-S1, i-S2, i-S3 kunye ne-R4, ngaloo ndlela ibangela ukuba i-thyristor yeendlela ezimbini ivule, i-VT nayo iya kuvula, kwaye i-H iya kuvula, iqonda umsebenzi wokulawula ukukhanya ngokuzenzekelayo.Emva kokuba ucango luvaliwe, imagnethi ilawula i-KD, unxibelelwano luvula, umbane we-9V uyeka ukutshaja i-C1, kwaye isekethe ingena kwimeko yokulibaziseka.I-C1 iqala ukukhupha i-R3.Emva kwexesha lokulibaziseka, i-voltage kuzo zombini iziphelo ze-C1 yehla ngokuthe ngcembe ngaphantsi kombane wokuvula we-S1, i-S2 kunye ne-S3 (1.5v), kunye ne-S1, i-S2 kunye ne-S3 ziphinda ziqalise ukuqhawulwa, okukhokelela ekunqanyulweni kwe-B6, i-VT cutoff, kunye H ukucima, ukuqonda isibane kulibaziseke off umsebenzi.
