Isingeniso

Isilawuli siyidivayisi yomyalo eshintsha i-wiring yesifunda esikhulu noma isifunda sokulawula futhi sishintsha inani lokumelana kumjikelezo ngendlela enqunywe kusengaphambili ukuze ulawule ukuqala, ukulawula isivinini, ukubhuleka nokuhlehla kwemoto.Yakhiwe ngekhawunta yohlelo, irejista yemiyalelo, isiqophi semiyalelo, ijeneretha yesikhathi nesilawuli sokusebenza, “okuyisigungu esithatha izinqumo” ukuze sikhiphe imiyalo, okungukuthi, ukuhlanganisa nokuqondisa ukusebenza kwalo lonke uhlelo lwekhompyutha.

Izigaba eziyinhloko

Isilawuli sihlukaniswe saba yinhlanganisela yesilawuli se-logic kanye nesilawuli se-microprogram, futhi isilawuli ngasinye kwezimbili sinamandla nobuthakathaka baso.Idizayini yesilawuli se-commbinatorial logic inzima futhi iyinkimbinkimbi, futhi uma umklamo usuqedile, awukwazi ukuguqulwa noma ukunwetshwa, kodwa uyashesha.Isilawuli se-microprogram sikulungele ukuklama, isakhiwo silula, kulula ukusishintsha noma ukunwetshwa, futhi umsebenzi wokuguqula umyalo womshini udinga kuphela ukuhlanganisa kabusha i-microprogram ehambisanayo;Ukwengeza umyalo womshini, mane ungeze i-microprogram kumemori yokulawula, nokho, ngokwenza uhlelo oluncane.Ukuqhathanisa okuqondile kungokulandelayo: Isilawuli se-commbinatorial logic, esaziwa nangokuthi isilawuli sezintambo eziqinile, sakhiwe amasekhethi anengqondo futhi sincike ngokuphelele kuhadiwe ukuze kufezwe umsebenzi weziyalezo.

Isebenza kanjani

Isilawuli se-electromagnetic chuck: i-ac voltage 380V ngemva kwebhakede le-transformer, isilungisa kabusha sibe ngu-110V DC ngokusebenzisa idivayisi yokulawula singene ku-chuck ngalesi sikhathi i-chuck idonsa uzibuthe, i-demagnetization ngokusebenzisa i-reverse voltage circuit, isilawuli ukufeza umsebenzi wokuqeda uzibuthe.

Isilawuli Sokulawula Ukufinyelela: Isilawuli sokulawula ukufinyelela sisebenza ngamamodi amabili.Enye imodi yokuhlola, kanti enye imodi yokuqaphela.Kumodi yokugada, isilawuli sithumela ngokuqhubekayo ikhodi yombuzo kumfundi futhi sithola umyalo wokuphendula ovela kumfundi.Le phethini ihlala kuze kube yilapho umfundi ezwa ikhadi.Lapho umfundi wekhadi ezwa ikhadi, umfundi wekhadi ukhiqiza izimpendulo ezihlukene emyalweni wokuhlola wesilawuli, kulo myalo wokuphendula, umfundi wekhadi udlulisela idatha yekhodi yangaphakathi yekhadi lenzwa kusilawuli sokulawula ukufinyelela, ukuze isilawuli sokulawula ukufinyelela singene imodi yokuqaphela.Kumodi yokuqaphela yesilawuli sokulawula ukufinyelela, isilawuli sokulawula ukufinyelela sihlaziya ikhodi yangaphakathi yekhadi lokungeniswa, siyiqhathanise nedatha yekhadi egcinwe kudivayisi, futhi sisebenzisa izenzo ezilandelayo.Ngemva kokuba isilawuli sokufinyelela siqedele isenzo sokuthola idatha, sizothumela umyalo wokuphendula umfundi wekhadi, ukuze umfundi wekhadi abuyele esimweni, futhi ngesikhathi esifanayo, isilawuli sokulawula ukufinyelela sizobuyela kumodi yokugada.
