1. Mapangidwe a switch circuit
Pamene chizindikiro cholowera cha ui chili chochepa, transistor V1 ili m'malo odulidwa, magetsi opangira kuwala mu optocoupler B1 ali pafupifupi ziro, ndipo kukana pakati pa zotulutsa Q11 ndi Q12 ndi zazikulu, zomwe ndi zofanana ndi kusinthana "kuzimitsa";Pamene ui ili pamwamba, v1 imayatsidwa, LED mu B1 yayatsidwa, ndipo kukana pakati pa Q11 ndi Q12 kumachepetsedwa, komwe kuli kofanana ndi kusintha "pa".Derali liri pamayendedwe apamwamba chifukwa Ui ndi yotsika ndipo chosinthira sichimalumikizidwa.Momwemonso, chifukwa palibe chizindikiro (Ui ndi mlingo wochepa), kusinthana kumayatsidwa, kotero kumakhala mu chikhalidwe chochepa cha conduction.
2. Mapangidwe a logic circuit
Derali ndi dera la AND gate logic circuit.Mawu ake omveka ndi P=AB Machubu awiri a chithunzithunzi pachithunzichi amalumikizidwa motsatizana.Pokhapokha pamene milingo yolowera A=1 ndi B=1, zotuluka P=1
3. Kuphatikizika kwa dera lakutali lolumikizana
Liniya yokulitsa mphamvu ya dera imatha kutsimikizika posankha bwino kukana komwe kulipo pakali pano Rl ya dera lowala ndikupangitsa kuti chiŵerengero chaposachedwa cha B4 chikhale chokhazikika.
4. Lembani voteji yokhazikika yokhazikika
Machubu oyendetsa ayenera kugwiritsa ntchito ma transistors okhala ndi voteji yayikulu kupirira.Pamene voteji linanena bungwe kuwonjezeka, kukondera voteji wa V55 ukuwonjezeka, ndi kutsogolo panopa kuwala emitting diode mu B5 kumawonjezeka, kotero kuti inter-electrode voteji wa photosensitive chubu amachepetsa, kukondera voteji wa kusintha chubu kukhala mphambano amachepetsa, ndi kukana mkati kumawonjezeka, kotero kuti voteji linanena bungwe amachepetsa, ndi linanena bungwe voteji amakhalabe okhazikika
5. Dongosolo lodzilamulira lokha la kuyatsa holo
A ndi ma seti anayi a masiwichi amagetsi a analoji (S1 ~ S4): S1, S2 ndi S3 amalumikizidwa molumikizana (zomwe zimatha kuwonjezera mphamvu yoyendetsa ndi anti-kusokoneza) pakuzungulira kochedwa.Akalumikizidwa ndi magetsi, njira ziwiri za thyristor VT zimayendetsedwa ndi R4 ndi B6, ndipo VT imayendetsa mwachindunji kuyatsa kwaholo H;S4 ndi chotchinga chakunja cha photosensitive resistor Rl amapanga dera lozindikira kuwala kozungulira.Chitseko chikatsekedwa, KD ya bango yotsekedwa yomwe imayikidwa pachitseko imakhudzidwa ndi maginito pakhomo, ndipo kukhudzana kwake kumatsegulidwa, S1, S2 ndi S3 ali mu data lotseguka.Madzulo, mwininyumbayo anapita kunyumba natsegula chitseko.Maginito anali kutali ndi KD, ndipo kukhudzana kwa KD kudatsekedwa.Panthawiyi, magetsi a 9V adzaperekedwa ku C1 kupyolera mu R1, ndipo voteji pamapeto onse a C1 posachedwa idzafika ku 9V.Mpweya wokonzanso udzapangitsa LED mu B6 kuwala kupyolera mu S1, S2, S3 ndi R4, motero kuyambitsa thyristor ya njira ziwiri kuyatsa, VT idzayatsanso, ndipo H idzayatsa, pozindikira ntchito yowongolera kuyatsa.Chitseko chikatsekedwa, maginito amalamulira KD, kukhudzana kumatsegulidwa, magetsi a 9V amasiya kulipira C1, ndipo dera limalowa m'nthawi yochedwa.C1 imayamba kutulutsa R3.Pambuyo pa kuchedwa, magetsi kumapeto onse a C1 amatsika pang'onopang'ono pansi pa magetsi otsegulira a S1, S2 ndi S3 (1.5v), ndipo S1, S2 ndi S3 zimayambiranso kudulidwa, zomwe zimapangitsa kuti B6 cutoff, VT cutoff, ndi H kuzimitsa, kuzindikira kuchedwa kwa nyali kuzimitsa ntchito.
