Menene manufar masu ɗaukar hoto a kan guntuTushen wutan lantarkiPins?
Yayinda Injiniyoyin yanar gizo da aka sani da aka san cewa masu ɗaukar hoto gaba daya suna ba da ayyuka na farko guda huɗu: kwalliya, hada DC yayin da ba da izinin ac to pass), tace, da ajiya na makamashi. A yau, zan mai da hankali kan yin bayanin aikin da bai dace ba.
Nau'in nau'ikan abubuwan da suka dace
Hoton da ke sama yana nuna wani ɓangare na wani yanki na Microctroller na ƙaramin wutar lantarki na Microcontroler na samar da wutar lantarki na lantarki. Wannan mcu yana buƙatar manyan hanyoyin wutar lantarki guda biyu, waɗanda yawanci ke kawo ta hanyar ldo (mai sarrafawa kaɗan), kamar LM1117.
Me yasa masu ɗaukar hoto sun zama dole
Yayinda Ldos gaba daya ya ba da ingantattun voltages idan aka kwatanta daCanza DC-DC(misali, TPS5430), har ma da voltages na ldo-ba zai iya nuna rashin iya nuna rashin iya nuna rashin iya nuna rashin iya yin amfani da kwakwalwan kwamfuta na babban aiki ba. Don magance wannan, muna sanya masu ɗaukar hoto a kusa da filayen wutar lantarki. Wadannan masu karfin wadannan karuwa suna ɗaukar madaidaicin-mitar wutar lantarki, suna karkatar da shi a ƙasa, don hakan tabbatar da guntu ya samo tushen wutar lantarki na DC. Don ingantaccen aiki, masu ɗaukar hoto dole ne a sanya su kusa da yadda zai yiwu zuwa fil na guntu.
Me yasa aka yi amfani da City 0.1μf?
Lokacin da nazarin mutuwar iko, sau da yawa muna bincika Capacitor kamar wannan hanyar, a ƙananan mitoci, capacitor da farko ayyuka a matsayin tace. Koyaya, kamar yadda mitar ke ƙaruwa, bangaren rashin ikon kawowa ya zama masu mahimmanci kuma a ƙarshe ya mamaye su. Bayan takamaiman bakin mitar, yawan tasirin capacitor yana raguwa. Wannan yana nufin cewa ababban mitsies, Capacortive ba ya nuna halin "tsarkakakken" tsarkakakken ". Ainihin halayen tace na Capacitor ana ba da alama a cikin kwana a ƙasa:
Daga kwana, da kyau tace faruwa a mafi karancin ra'ayi nawanda ba a sani bacurve (mafi ƙaranci). Koyaya, kamar yadda mita yana ƙaruwa, mai ɗaukar lamba 0.1μf ta zama ƙasa da idan aka kwatanta da 0.01μf Capacitor. A ko da mafi girma m hourquencies, karami mai karfin gwiwa (misali, 0.001μf) ana buƙatar su don ingantaccen tace.
Magani: Paralle masu ɗaukar hoto
Don magance wannan iyakancewa, yawancin ƙira masu da'awa suna amfani da masu ɗaukar hoto a cikin layi ɗaya tare da ƙimar kyalawa daban-daban. Ta hanyar hada karfi na dabi'u daban-daban, ingantaccen kewayon mitarancin kewayawa yana fadada kewayon da mafi kyawun abin mamakin a kan babban spectrum. Wannan hanyar tana ba da damar inganta wasan kwaikwayon da aka yi akan fadada kewayon mitoci.
