Lub Ntev Lub Neej Dc Tsav Tsav Lub Hoobkas qhia koj cov qauv tswj kev nrawm ntawm DC lub cev muaj zog tsav
Kev tswj cov qauv ntawm lub nrawm ntawm DC lub cev muaj zog:
MCS-51 series microcontroller yog siv los tswj PWM teeb liab los tswj cov kev ceev ntawm DC tsav tsav tsheb. Nws yog ib yam uas peb tau sim los kawm ntev ntev. Cov nyhuv ntawm ib qho khoob tau dhau los ua ntau dua thiab pom tseeb.
PWM vuam tuaj yeem tsim los ntawm cov phiaj xwm ib qho nti nrog PWM tso tawm, lossis lawv tuaj yeem siv siv PWM siab rau lub puab tsaig. Thaum qhov zaus ntawm PWM yoj siab dhau lawm, nws yuav tsum tau siv hluav taws xob ntau lub raj xa los ntawm DC tsav tsav. Thaum nws zaus muaj tsawg dhau, lub suab nrov electromagnetic tawm kuj tseem loj. Hauv kev siv tswv yim, thaum PWM nthwv dej zaus yog li 18KHz, Nws ua haujlwm zoo dua.
Tus kho vajtse Circuit yog tsim raws li lub hauv paus ntsiab lus ntawm Circuit Court. Qhov ntsuas ntawm qhov ntsuas tuaj yeem ntsuas qhov ceev ntawm DC lub cev muaj zog tus tswv xeev. Los ntawm txhua qhov kev sib hloov ntawm lub cev muaj zog, lub ntsuas hluav taws xob ceev ntawm infrared khub tub yees yuav tau tsim, thiab thaum kawg qhov tshwj xeeb ntawm qib sib txawv ceev tuaj yeem paub tau los ntawm kev dhau tus nqi sib txawv hauv 1S sijhawm. Tus naj npawb ntawm cov lem hloov nyob rau hauv lub sijhawm ruaj khov yog txawv, thiab qhov chaw nyob sib piv yog qhov sib txawv. Qhov loj ntawm tus tau txais infrared khub ceev ntsuas Circuit Court yog txawv. Thaum kawg, tus nqi tshwj xeeb ntawm lub nrawm tuaj yeem tshwm hauv digital Guanshang los ntawm software software.
Kev siv cov khoom hluav taws xob photoelectric sensors rau DC lub zog tsav ceev ntsuas lub ntsuas yog qhov qauv zoo tshaj, tab sis cov peev txheej muaj qhov txwv, yog li peb yuav tsum tau txuas ntxiv dua tshiab thiab txhim kho cov thev naus laus zis no.
