Intshayelelo

Umlawuli sisixhobo somyalelo esitshintsha i-wiring yesiphaluka esiphambili okanye isiphaluka solawulo kwaye sitshintshe ixabiso lokumelana kwisekethe kwi-oda elimiselweyo lokulawula ukuqala, ukulawula isantya, ukunyathela kunye nokuguqulwa kwemoto.Iqulunqwe yikhawuntara yeprogram, irejista yemiyalelo, idikhowuda yemiyalelo, ijenereyitha yexesha kunye nesilawuli sokusebenza, "iqumrhu elithatha izigqibo" lokukhupha imiyalelo, oko kukuthi, ukulungelelanisa nokusebenza kwayo yonke inkqubo yekhompyutha.

Ukuhlelwa okuphambili

Umlawuli uhlukaniswe umlawuli we-logic edibeneyo kunye nomlawuli we-microprogram, kwaye ngamnye kubalawuli ababini banamandla kunye nobuthathaka.Uyilo lwesilawuli sengqiqo edibeneyo luyinkathazo kwaye lunzima, kwaye xa uyilo lugqityiwe, alunakuguqulwa okanye lwandiswa, kodwa lukhawuleza.Umlawuli we-microprogram ulungele ukuyila, isakhiwo silula, kulungele ukuguqula okanye ukwandisa, kwaye umsebenzi wokuguqula umyalelo womatshini ufuna kuphela ukubuyisela i-microprogram ehambelanayo;Ukongeza umyalelo womatshini, yongeza nje i-microprogram kwimemori yokulawula, nangona kunjalo, ngokwenza i-microprogram.Uthelekiso oluthile lulolu hlobo lulandelayo: Umlawuli we-combinator logic, owaziwa ngokuba ngumlawuli we-wiring onzima, uqulunqwe ngeesekethe ze-logic kwaye uthembele ngokupheleleyo kwi-hardware ukufezekisa umsebenzi wemiyalelo.

Ingaba isebenza kanjani

Isilawuli se-electromagnetic chuck: i-ac voltage 380V emva kwe-buck ye-transformer, isilungisi kwi-110V DC ngesixhobo sokulawula ukuya kwi-chuck ngeli xesha i-chuck yenziwe ngumagnetic, i-demagnetization ngokusebenzisa i-reverse voltage circuit, isilawuli ukufezekisa umsebenzi we-demagnetization.

UMlawuli woLawulo lokuFikelela: Umlawuli wokulawula ukufikelela usebenza ngeendlela ezimbini.Enye yimo yokuhlola, kwaye enye yimowudi yokuqaphela.Kwimo yokugada, umlawuli ngokuqhubekayo ethumela ikhowudi yombuzo kumfundi kwaye ufumana umyalelo wokuphendula ovela kumfundi.Le pateni ihlala de umfundi alive ikhadi.Xa umfundi wekhadi ebona ikhadi, umfundi wekhadi uvelisa iimpendulo ezahlukeneyo kumyalelo wokuhlola womlawuli, kulo myalelo wokuphendula, umfundi wekhadi uhambisa i-sensor yekhadi ledatha yekhowudi yangaphakathi kumlawuli wokulawula ukufikelela, ukuze umlawuli wokufikelela angene indlela yokuqonda.Kwimodi yokuqaphela umlawuli wolawulo lokufikelela, umlawuli wokulawula ukufikelela uhlalutya ikhowudi yangaphakathi yekhadi le-induction, liqhathanise nedatha yekhadi egcinwe kwisixhobo, kwaye isebenzise izenzo ezilandelayo.Emva kokuba umlawuli wokufikelela agqibe isenzo sokufumana idatha, uya kuthumela umyalelo wokuphendula kumfundi wekhadi, ukwenzela ukuba umfundi wekhadi abuyele kwilizwe, kwaye ngelo xesha, umlawuli olawula ukufikelela uya kubuyela kwimodi yokujikeleza.
