Ihame rya moderi moderi.
Icyiciro cya modulator ni umuzenguruko icyiciro cyabatwara kiyobowe nikimenyetso cyahinduwe. Hariho uburyo bubiri bwingenzi bwo guhinduranya icyiciro cya sine: guhindagura icyiciro cyerekezo no guhinduranya icyiciro kitaziguye. Icyiciro cya modulasiyo ni uguhindura mu buryo butaziguye ibipimo bya resonant loop muguhindura ibimenyetso, kugirango icyiciro cyo guhinduranya kibyare mugihe ibimenyetso byabatwara byanyuze mumurongo wa resonant hanyuma bigakora icyiciro cya modulasiyo. Guhindura icyiciro kitaziguye ni ukubanza guhindura amplitude yumuvuduko wahinduwe, hanyuma ugahindura amplitude ihinduka mukiciro cyo guhinduka, kugirango ugere kubice byahinduwe.
Kumenyekanisha neza kwicyiciro cya modulisiyo itaziguye no guhinduranya icyiciro kitaziguye
Icyiciro cya modulasiyo itaziguye: ukoresheje ibimenyetso byahinduwe kugirango uhindure byimazeyo ibipimo bya resonant loop, kugirango ibimenyetso byabatwara binyuze muri resonant loop icyiciro. Ubu buryo buroroshye kandi butaziguye, ariko busaba kugenzura neza ibipimo byumuzingi wa resonant.
Guhindura icyiciro kitaziguye: amplitude yumurongo wahinduwe ihindurwa mbere, hanyuma ihinduka rya amplitude rihinduka mubyiciro. Ubu buryo bwakozwe na Armstrong mu 1933 kandi bwitwa uburyo bwa Armstrong modulation.
pulse icyiciro cya modulator: Module icyiciro cya moderi ihindura ibyasohotse icyiciro cya moderi ya moderi ikoresheje ibyinjira byinjira mubisohoka mubikoresho bigenzura. Iyo igikoresho cya CNC gisohoye imbere cyangwa kugaburira ibiryo bigaburira, ibisohoka bya moderi ya moderi moderi izatera imbere cyangwa itinda ibimenyetso byerekanwa nicyiciro gikwiranye.
MCU imenya icyiciro cya digitale ihindura: imbarutso yisaha yisaha, ongeraho cyangwa ukuremo pulse yinyongera kugirango uhindure ibyasohotse kuri compteur, kugirango tumenye ihinduka ryicyiciro.
Urugero rwo gusaba icyiciro
Sisitemu ihindagurika ya sisitemu yo guhinduranya: Icyiciro modulator nigice cyingenzi cyibintu byahinduwe na sisitemu yo guhindura igihe, guhindura imikorere ya moteri mugucunga icyiciro cyigihe cya valve.
Device Igikoresho cyindishyi zidasubirwaho: Kamera ihindura nigikoresho cyindishyi zingufu zikoreshwa mugukomeza ingufu za voltage muri sisitemu yamashanyarazi.
Ikosa ryimikorere yibinyabiziga bigaragarira cyane nkibimenyetso byikinyabiziga cyananiranye, ibi bimenyetso birimo:
Igenzura rya voltage risenyuka : gusenyuka kwa transistor ya FET cyangwa Darlington imbere yumubyigano wa voltage, bigatuma umuyaga wibyishimo utabura, bigatuma ingufu za generator zisohoka, na bateri ikarenza urugero.
Generator yangiritse : Niba amashanyarazi yangiritse, ingufu zavuyemo ziragabanuka kandi bateri ntishobora kwishyurwa.
Umuyoboro cyangwa Darlington umuyoboro wangiritse wangiritse:
Ikimenyetso cya Batiri kiri mugihe nta mashanyarazi aboneka : Ikimenyetso cya batiri gishobora kuba kubera ko nta mashanyarazi aboneka, cyangwa birashobora guterwa n’amashanyarazi menshi. Iyo voltage ya bateri igabanutse munsi ya volt 10, moteri iranyeganyega, biragoye gutangira, cyangwa ntishobora kwihuta no guhagarara.
Ibi bimenyetso byerekana ikibazo cya sisitemu y'amashanyarazi y'imodoka, ishobora kugira ingaruka mbi kumikorere yimodoka. Kubwibyo, gusuzuma mugihe no gusana ibyo byananiranye ni ngombwa cyane .
Mubyongeyeho, ibimenyetso byamakosa yimodoka isimbuza ibinyabiziga nabyo birimo kutishyuza, kwishyuza amashanyarazi ni mato cyane cyangwa manini cyane, kandi ayo makosa ashobora kuba afitanye isano namakosa yubuyobozi. Kurugero, kunanirwa kwishyurwa birashobora guterwa numukandara wa generator wacitse, umurongo ushimishije wa moteri cyangwa umurongo wo kwishyuza, hamwe no guhuza nabi hagati ya brush na mpeta. Umuyoboro wamashanyarazi ni muto cyane birashobora guterwa no guhuza nabi kumurongo wumuriro, kunyerera kumukandara wa moteri, kunanirwa kwa generator cyangwa voltage igenga voltage iri hasi cyane. Amashanyarazi yishyurwa ni manini cyane ashobora kuba kubera ko kugenzura amabwiriza ya voltage agaciro ari hejuru cyane .
Muri make, ibimenyetso byo kunanirwa kwicyiciro cyikinyabiziga harimo kwishyurwa hejuru ya bateri, kunanirwa kwa bateri, urumuri rwerekana bateri, nibindi, bishobora kugira ingaruka kumikorere isanzwe yimodoka. Kubwibyo, birakenewe gusuzuma no gusana amakosa ya moderi yimodoka mugihe.
Niba ushaka kumenya byinshi, komeza usome izindi ngingo kururu rubuga!
Nyamuneka uduhamagarire niba ukeneye ibicuruzwa nkibi.
Zhuo Meng Shanghai Auto Co, Ltd. yiyemeje kugurisha MG & MAUXS ibice byimodoka ikaze kugura.
