K1 nthawi zambiri imatsekedwa kukhudzana K1-1, mbali ina yapakatikati yolumikizirana K1 nthawi zambiri imatsekedwa kukhudzana K1-1, mzati woyipa wa electrolytic capacitor C1 ndi malekezero a capacitor C3 amalumikizidwa ndi malo opangira magetsi, mbali ina ya capacitor C3 yolumikizidwa ndi pin 3 ya dual-time base integrated chip NE556, pini 4 ya dual time base integrated chip NE556 imalumikizidwa ku zabwino. Mzati wa electrolytic capacitor C2 ndi mapeto ena a resistor R2 pa nthawi yomweyo, ndi mzati zoipa electrolytic capacitor C2 chikugwirizana ndi nthaka magetsi, ndi mzati zoipa electrolytic capacitor C2 chikugwirizana ndi magetsi pansi. Mzati yoyipa ya C2 imalumikizidwa ndi malo opangira magetsi, pini 5 yapawiri-nthawi yophatikiza chip NE556 imalumikizidwa ku malekezero amodzi a resistor R3, malekezero ena a resistor R3 alumikizidwa ndi gawo labwino la comparator yamagetsi. , gawo loyipa la comparator yamagetsi limalumikizidwa ndi mtengo wabwino wa diode D1 ndi malekezero ena a resistor R4 nthawi yomweyo, mzati woyipa wa diode D1 umalumikizidwa ndi mphamvu. malo ogulitsa, ndipo kutulutsa kwa comparator yamagetsi kumalumikizidwa kumapeto kwa resistor R5, mbali ina ya resistor R5 imalumikizidwa ndi PNP triplex. Linanena bungwe la comparator voteji chikugwirizana ndi mbali imodzi ya resistor R5, mapeto ena a resistor R5 chikugwirizana m'munsi mwa PNP transistor VD1, wokhometsa PNP transistor VD1 chikugwirizana ndi mtengo wabwino wa diode. D2, mtengo woipa wa diode D2 umalumikizidwa kumapeto kwa resistor R6, kumapeto kwa capacitor C4, ndi chipata cha MOSFET nthawi yomweyo. nthawi, mapeto ena a resistor R6, mapeto ena a capacitor C4, ndi mapeto ena a wapakatikati kulandirana K1 onse olumikizidwa ku dziko magetsi ndi mapeto ena a wapakatikati kulandirana K1 chikugwirizana ndi gwero la gwero laMOSFET.

MOSFET posungira dera, pamene A amapereka chizindikiro chotsika choyambira, panthawiyi cholumikizira chapawiri chophatikizira NE556, chip NE556 pin 5 chophatikizira chip NE556 pin 5 kutulutsa kwapamwamba, mulingo wapamwamba kulowa mugawo labwino la comparator yamagetsi, zoyipa. gawo lothandizira la comparator voteji ndi resistor R4 ndi diode D1 kupereka voteji Buku, pa nthawi ino, voteji comparator linanena bungwe mkulu mlingo, mkulu mlingo kuti Triode VD1 imayendetsa, yomwe ikuyenderera kuchokera kwa wokhometsa wa triode VD1 imayitanitsa capacitor C4 kudzera mu diode D2, ndipo nthawi yomweyo, MOSFET Q1 imachita, panthawiyi, coil ya K1 yapakatikati imalowetsedwa, ndipo K1 yapakatikati imalowetsedwa. chatsekedwa kukhudzana K 1-1 ndi kusagwirizana, ndipo pambuyo wapakatikati kulandirana K1 zambiri chatsekedwa kukhudzana K 1-1 ndi atachotsedwa, magetsi a DC opita ku 1 ndi 2 mapazi a dual-time base Integrated chip NE556 amapereka mphamvu yamagetsi yosungidwa mpaka voteji pa pini 1 ndi pini 2 ya chip NE556 yapawiri-time integrated chip NE556 iperekedwa ku 2/ 3 ya magetsi operekera, chipangizo chophatikizira chapawiri-nthawi ziwiri NE556 chimakhazikitsidwanso, ndipo pini 5 ya chip NE556 yapawiri-time base integrated chip NE556 imabwezeretsedwa ku mlingo wochepa, ndipo mabwalo wotsatira sagwira ntchito, pamene panthawiyi, capacitor C4 imatulutsidwa kuti ikhalebe ndi MOSFET Q1 conduction mpaka kumapeto kwa capacitance C4 kutulutsa ndi kutulutsidwa kwapakatikati kwa K1 koyilo, kulumikiza kwapakatikati kwa K1 nthawi zambiri kutsekedwa. K 11 chatsekedwa, pa nthawi iyi kudzera chatsekedwa wapakatikati kulandirana K1 kawirikawiri chatsekedwa kukhudzana K 1-1 adzakhala wapawiri nthawi maziko Integrated Chip NE556 1 phazi ndi 2 mapazi a voteji kumasulidwa, kwa nthawi yotsatira kwa wapawiri maziko Integrated Chip NE556 pini 6 kupereka otsika choyambitsa chizindikiro kupanga wapawiri maziko Integrated Chip NE556 kukonzekera.

Mawonekedwe ozungulira a pulogalamuyi ndi osavuta komanso achilendo, pomwe chip NE556 pini 1 ndi pini 2 ndikulipiritsa mpaka 2/3 yamagetsi operekera, chip NE556 chapawiri chikhoza kukhazikitsidwanso, chip chapawiri chophatikizika. NE556 pini 5 imangobwerera pang'onopang'ono, kuti mabwalo otsatirawa asagwire ntchito, kuti asiye kulipiritsa capacitor C4, ndipo pambuyo pake. kuyimitsa kulipiritsa kwa capacitor C4 yosungidwa ndi MOSFET Q1 conductive, pulogalamuyi imatha kusunga mosalekeza.MOSFETQ1 conductive kwa 3 masekondi.

Zimaphatikizapo resistors R1-R6, electrolytic capacitors C1-C3, capacitor C4, PNP transistor VD1, diode D1-D2, intermediate relay K1, voltage comparator, dual time base integrated chip NE556 ndi MOSFET Q1, pini 6 ya nthawi ziwiri zophatikizidwa. chip NE556 imagwiritsidwa ntchito ngati cholowetsa chizindikiro, ndipo mbali imodzi ya resistor R1 imalumikizidwa ndi pini 14 ya dual time base integrated chip NE556, resistor R2, pini 14 ya dual time base integrated chip NE556 ndi pini 14 ya dual time base integrated chip NE556, ndi resistor R2 yolumikizidwa ndi pini 14 ya nthawi yapawiri base Integrated chip. NE556. pini 14 yapawiri-nthawi base Integrated Chip NE556, mbali imodzi ya resistor R2, mbali imodzi ya resistor R4, PNP transistor

Ndi mtundu wanji wa ntchito?

Pamene A ikupereka chizindikiro chochepa choyambira, ndiye kuti chipangizo chophatikizira chapawiri-nthawi ziwiri NE556 chimayikidwa, chophatikizira chapawiri-nthawi yophatikiza chip NE556 pin 5 kutulutsa kwapamwamba, mulingo wapamwamba mugawo labwino la comparator yamagetsi, kuyika kwa gawo loyipa la voltage comparator ndi resistor R4 ndi diode D1 kuti apereke voteji, nthawi ino, voteji comparator linanena bungwe mkulu mlingo, mkulu mlingo wa transistor VD1 conduction, panopa umayenda kuchokera wokhometsa transistor VD1 kudzera diode D2 kwa capacitor C4 nawuza, pa nthawi iyi, wapakatikati relay K1 koyilo kuyamwa, wapakatikati relay K1 koyilo kuyamwa. Zomwe zikuyenda kuchokera kwa osonkhanitsa transistor VD1 zimaperekedwa ku capacitor C4 kudzera mu diode D2, ndipo nthawi yomweyo,MOSFETQ1 imachita, panthawiyi, koyilo yapakatikati yolumikizirana K1 imayamwa, ndipo kulumikizana kwapakatikati kwa K1 komwe kumatsekedwa kawirikawiri K 1-1 kumalumikizidwa, ndipo pambuyo polumikizirana wapakatikati K1 nthawi zambiri-chatsekedwa kukhudzana K 1-1 imachotsedwa, mphamvu magetsi operekedwa ndi gwero lamagetsi la DC ku 1 ndi 2 mapazi a dual timebase Integrated chip NE556 amasungidwa mpaka Pamene voteji pa pini 1 ndi pini 2 yapawiri-time base Integrated chip NE556 imaperekedwa ku 2/3 yamagetsi operekera, chipangizo chophatikizira chapawiri-nthawi ziwiri NE556 chimangokhazikitsidwanso, ndipo pini 5 ya chipangizo chophatikizira chapawiri-nthawi ziwiri NE556 imangodziyika yokha. kubwezeretsedwa kumlingo wochepa, ndipo mabwalo otsatirawa sagwira ntchito, ndipo panthawiyi, capacitor C4 imatulutsidwa kuti isunge MOSFET Q1 conduction. mpaka mapeto a kumaliseche kwa capacitor C4, ndi koyilo wapakatikati kulandirana K1 amamasulidwa, ndi wapakatikati kulandirana K1 kawirikawiri chatsekedwa kukhudzana K 1-1 ndi kusagwirizana. Relay K1 kawirikawiri chatsekedwa kukhudzana K 1-1 chatsekedwa, nthawi ino kudzera chatsekedwa wapakatikati kulandirana K1 kawirikawiri chatsekedwa kukhudzana K 1-1 adzakhala wapawiri-nthawi m'munsi Integrated Chip NE556 1 mapazi ndi mapazi 2 pa kumasulidwa voteji, kwa nthawi yotsatira Chip NE556 Pin 6 yapawiri-nthawi yophatikiza kuti ipereke chizindikiro choyambira kuti chikhale chotsika, kuti akonzekere kukhazikitsidwa kwapawiri-nthawi yapawiri yophatikizira chip NE556.
