Ka'idar modulator lokaci.
Modulator mai juzu'i shine kewayawa wanda lokacin mai ɗaukar kaya ke sarrafa siginar da aka daidaita. Akwai manyan hanyoyi guda biyu na sine wave lokaci daidaitawa: kai tsaye lokaci daidaitawa da kuma kaikaice lokaci modulation. Daidaitaccen lokaci kai tsaye shine canza sigogin madauki na resonant kai tsaye ta hanyar daidaita sigina, ta yadda canjin lokaci ya kasance lokacin da siginar mai ɗaukar hoto ya wuce ta hanyar madauki mai resonant kuma ya samar da igiyoyin daidaitawa lokaci. Canjin lokaci kai tsaye shine a fara canza girman maɗaukakin igiyar ruwa, sannan a canza canjin girman zuwa canjin lokaci, ta yadda za'a cimma daidaituwar lokaci. "
Ƙimar fahimtar kai tsaye na daidaitawar lokaci kai tsaye da daidaitawar lokaci kai tsaye
Tsarin lokaci kai tsaye: ta yin amfani da siginar da aka daidaita don canza sigogin madauki na resonant kai tsaye, ta yadda siginar mai ɗaukar hoto ta hanyar jujjuyawar lokaci na madauki. Wannan hanya mai sauƙi ce kuma kai tsaye, amma tana buƙatar daidaitaccen iko na sigogin da'irar resonant.
Canjin lokaci kaikaice: an fara canza girman girman igiyoyin da aka daidaita, sannan kuma ana canza girman girman zuwa canjin lokaci. Armstrong ne ya kirkiro wannan hanya a cikin 1933 kuma ana kiranta hanyar Armstrong modulation.
pulse period modulator: The pulse period modulator yana canza lokacin fitarwa na na'urar sarrafa bugun jini ta hanyar shigar da bugun jini na na'urar sarrafa lamba. Lokacin da na'urar CNC ta fitar da bugun jini na gaba ko baya, fitowar na'urar motsa jiki na bugun jini zai ci gaba ko rage siginar tunani ta madaidaicin kusurwar lokaci. "
MCU yana gane mai canza lokaci na dijital: ƙidayar ƙira ta bugun bugun agogo, ƙara ko rage ƙarin bugun bugun jini don canza lokacin fitarwa na counter, don gane canjin lokaci. "
Misalin aikace-aikace na modulator lokaci
Tsarin lokaci na bawul mai canzawa: Modulator na lokaci shine maɓalli mai mahimmanci na tsarin lokaci mai canzawa, haɓaka aikin injin ta hanyar sarrafa lokaci na lokacin bawul. "
Na'urar ramuwa mai amsawa: Kamara mai daidaitawa shine na'urar ramuwa mai amsawa da ake amfani da ita don kula da ma'aunin wutar lantarki a tsarin wutar lantarki. "
Laifin mai sarrafa lokaci na motoci yana bayyana musamman azaman alamun gazawar mai sarrafa kayan lantarki, waɗannan alamun sun haɗa da:
Rushewar wutar lantarki mai sarrafa wutar lantarki: rushewar FET ko Darlington transistor a cikin na'ura mai sarrafa wutar lantarki, yana haifar da tashin hankali na halin yanzu ya ƙare, yana haifar da ƙarfin fitarwa na janareta ya tashi, kuma baturin ya yi caji.
Generator ya lalace: Idan janareta ya lalace, ƙarfin fitarwa yana raguwa kuma ba za'a iya cajin baturi ba.
Effector ko Darlington bututun buɗaɗɗen kewayawa lalacewa: Idan mai yin tasiri ko bututun Darlington ya lalata buɗaɗɗen kewayawa, janareta haɓaka iskar gubar ta ƙasa.
Alamar baturi yana kunne lokacin da ba a samar da wutar lantarki: Alamar baturi na iya kasancewa a kunne saboda ba a samar da wutar lantarki, ko kuma yana iya zama saboda yawan ƙarfin lantarki. Lokacin da ƙarfin baturi ya faɗi ƙasa da 10 volts, injin yana motsawa, yana da wuyar farawa, ko ba zai iya hanzari da tsayawa ba.
Wadannan alamomin suna nuna matsala tare da tsarin lantarki na motar, wanda zai iya yin mummunar tasiri akan aikin motar. Don haka, bincikar ganowar lokaci da gyara waɗannan gazawar yana da matukar muhimmanci.
Bugu da kari, alamun kuskuren na'urar canza mota kuma sun hada da babu caji, cajin halin yanzu ya yi ƙanƙanta ko babba, kuma waɗannan kurakuran na iya kasancewa da alaƙa da laifin mai sarrafa. Misali, gazawar cajin na iya zama sanadin karyewar bel na janareta, karyar layin jan wutar lantarki ko layin caji, da rashin kusanci tsakanin goga da zoben zamewa. Cajin halin yanzu ya yi ƙanƙanta na iya zama saboda rashin mu'amalar layin caji, zamewar bel ɗin tuƙi, gazawar janareta ko ƙarfin wutar lantarki mai kayyadewa ya yi ƙasa da ƙasa. Cajin halin yanzu yana da girma yana iya zama saboda ƙimar wutar lantarki mai daidaitawa ta yi girma sosai.
A taƙaice, alamun gazawar modulator na abin hawa sun haɗa da cajin baturi, gazawar baturi, hasken baturi, da dai sauransu, wanda zai iya shafar aikin mota na yau da kullun. Don haka, ya zama dole a gano tare da gyara kuskuren na'urar modulator a cikin lokaci.
Idan kana son ƙarin sani, ci gaba da karanta sauran labaran kan wannan rukunin yanar gizon!
Da fatan za a kira mu idan kuna buƙatar irin waɗannan samfuran.
