Kev tsim hluav taws xob niaj hnub yog ua raws li ob lub ntsiab lus tseem ceeb ntawm feem ntau circuits - semiconductor transistor thiab electromagnetic relay. Yog tias koj lub hlwb tshem tawm ob qhov kev tsim tawm no, nws nyuaj rau xav txog tias keeb kwm ntxiv ntawm noob neej yuav txhim kho li cas.
Tej zaum, yuav muaj kev hloov pauv Hnub Nyoog Nruab Nrab nyob ib puag ncig, lossis, ntawm qhov tsis sib xws, kev vam meej yuav tau mus raws txoj kev tswj hwm kev loj hlob ntawm cov kab mob lom. Tab sis cia peb tso cov kev xav no rau cov kws sau ntawv keeb kwm science. Ib yam yog qhov tseeb: lub tshuab hluav taws xob hluav taws xob rau txhua qhov hluav taws xob engineering yog tib yam li lub tshuab hluav taws xob sab hauv rau kev thauj mus los niaj hnub. Ntawd yog - ib qho khoom tseem ceeb tsis tau.
Electromagnetic relay ua haujlwm li cas?
Kev tsim ntawm lub hauv paus Circuit Court no yooj yim heev. Qhov no piav qhia nws qhov kev ntseeg siab: qee lub tsev tsim khoom tseem ua haujlwm relays txij xyoo 1940.
Ua ntej piav txog tus qauv tsim, nws yuav tsum nco ntsoov ib qho ntawm cov cai ntawm physics - electromagnetism. Nws yog lub npe hu hais tias nyob ib ncig ntawm txhua yam khoom uas ib tug hluav taws xob tam sim no hla, muaj ib tug tshwj xeeb yam teeb meem - ib tug hlau nplaum. Nws lub zog (muaj peev xwm) nyob ntawm ob qhov tsis muaj: tus nqitam sim no ntws thiab tus neeg xyuas pib ntev.
Qhov no yog qhov pom tseeb: yog tias txhua chav tsev ntawm qhov ntev tsim ib daim teb, ces qhov ntev ntawm tus neeg xyuas pib, qhov kev tshaj tawm cov nyhuv sib nqus. Qhov no txhais tau hais tias yog ib qho khoom siv hlau muab tso rau ntawm ib sab ntawm tus neeg xyuas pib, ces nws yuav cuam tshuam los ntawm kev txaus nyiam. Yog tias lawv tus nqi txaus, ces cov khoom yuav txav mus. Lwm qhov tseem ceeb yog qhov pom tseeb: nws tsis yooj yim heev los ua kom qhov kev siv zog los ntawm kev ua kom ntev ntawm tus neeg xyuas pib - lub cuab yeej yuav tsum compact, thiab tag nrho cov teb vector yuav tsum tau concentrated nyob rau hauv ib qho chaw, thiab tsis sprayed raws tag nrho cov khoom siv conductive.. Kev nce tam sim no kuj yog qhov tsis txaus ntseeg, vim nws ua rau cua sov ntau dhau thiab siv cov khoom siv tsis zoo. Txawm li cas los xij, muaj kev daws teeb meem.
Nws muaj nyob rau hauv kev siv tsis yog ib tug ncaj hlau, tab sis ib tug coil nrog ib tug core. Qhov no tso cai rau mais ntawm nyias hlau siv rau ntawm lub ntim me me.
Lub electromagnetic relay tsuas muaj xws li cov kauj hauv. Qhov thib ob ntawm cov qauv yog ib qho tshwj xeeb-zoo li tus hlau phaj nrog ib qib ntawm kev ywj pheej. Ntawd yog, thaum muaj qhov sib nqus sib nqus, lub phaj yog attracted rau sab kawg ntawm lub kauj. Thaum qhov tam sim no ploj mus, qhov kev txiav txim nres, thiab lub caij nplooj ntoos hlav rov qab muab lub phaj rov qab mus rau qhov qub.
Jumpers - ib pawg ntawm cov neeg tuaj yeem txav tau - raug kho ntawm qhov ntxim nyiam. Qhov thib ob ntawm lawv (rigidly tsau) nyob ze. Thaum lub phaj txav mus, cov neeg raug kaw. Yog ibkom suav nrog lawv nyob rau hauv ib qho kev sib tsoo, tom qab ntawd los ntawm kev tswj kev ua haujlwm ntawm lub kauj, koj tuaj yeem hloov cov kab txuas txuas. Qhov no yog li cas electromagnetic relay ua haujlwm. Los ntawm txoj kev, nyob ntawm txoj kev nyob ruaj khov, lawv tuaj yeem raug kaw ib txwm (qhib thaum muaj qhov sib nqus pom) thiab nquag qhib (sau ib lub voj voog).
Ib qho khoom siv hluav taws xob hloov pauv tam sim no hauv tus qauv tsim muaj cov coil tshwj xeeb ntawm tus neeg xyuas pib, thaj chaw uas tiv thaiv rattling vim qhov zaus ntawm qhov tam sim no.
