Ama-servos angamamodeli alungele izinhlelo zokusebenza ngaphandle kwalokho ezihlosiwe, njengokushayela ibhawodi yokukhiya. Kuhlelo lokusebenza olunjalo olungajwayelekile, inkathazo enkulu "ukuphoqa" i-servo ukuthi isebenze, ngoba idinga ukunika amandla i-waveform enemingcele ethile. Isifunda esichaziwe siyasikhulula enkingeni enjalo.
Izici
- Isixhumi se-servo esijwayelekile se-Hiten
- okokufaka kokulawula izifunda ezimbili
- ama-potentiometer amabili okunquma izindawo zokugcina zengalo ye-servo
- isikhathi sokuzungezisa ingalo egcwele: isekhondi elingu-1
- ukulungiswa okubushelelezi kokuma kwengalo (ngalinye
- inkomba yesimo - LED
- amandla kagesi 8÷18 V DC
Incazelo yesifunda
Umdwebo wohlelo lwesilawuli uboniswa kuMfanekiso 1. Uqukethe izinto ezimbalwa kuphela. I-D1 diode ivikela ekuxhumekeni okuphambene kwevolthi yokunikezelatage, isizinzisi se-US1 sihlinzeka ngo-5 V ukunika amandla i-servo, futhi ngesihlungi esengeziwe esinezici u-R3 ne-C3 siphinde sinike amandla isilawuli esincane se-US2. I-resistor ye-R4 ivikela okokufaka okukhethiwe kombuso, i-R5 ivikela ukukhishwa kwe-pulse yokulawula, i-R6 iphoqelela isimo esisebenzayo se-microcontroller, futhi i-R7 ikhawulela ukusebenza kwamanje kwe-D2 LED. I-R1 kanye ne-R2 potentiometers isetshenziselwa ukusetha amavolumu amabilitagamanani e-e, alawula kamuva amapharamitha wama-pulses kokuphumayo. Sixhuma umthamo wokunikezelatage kusixhumi se-PWR ukusuka kububanzi obungu-8…18 V, kuyilapho kusixhumi se-SERVO sixhuma i-servo, ngokuya ngezimpawu ebhodini. I-0 V noma i-5 V isetshenziswa ekuholeni okungu-2 kwesixhumi se-SW, esibeka i-servo kwesinye sezikhundla ezimbili. Ukusebenza kwesekethe kulawulwa uhlelo oluqukethwe kumemori ye-microcontroller, umdwebo wayo we-block uboniswa ku-Figure 2. I-TIMER? Isifunda sesikhathi siyikhawunta ye-16-bit eyayisetshenziselwa ukukhiqiza ukuphazamiseka njalo ngo-20 ms, ngaleyo ndlela kusungulwe isikhathi sokukhishwa kwe-waveform. Ukuphazamiseka kwenzeka lapho isibali sichichima. Ikhawunta yesikhathi isetshenziselwa ukunquma ubude besikhathi sokushaya kwenhliziyo.
Ukuqala kwayo kuvumelaniswa ngokuphazanyiswa okuvela ku-Timer1, futhi ukuchichima kwayo kukhiqiza ukuphazamiseka kwesibili okuqeda ukushaya kwenhliziyo futhi kumise ikhawunta. Isikhathi sokuphazamisa, kanjalo nobude be-pulse, sinqunywa ngokushintsha inani lokuqala lekhawunta, elilingana nomphumela wokuguqulwa kwe-A/C. Ngakho-ke, ukushintsha ivolumutage kububanzi obungu-0…5 V kokokufaka kwe-ADC, kubangela ushintsho kubude besikhathi sokushaya kwenhliziyo ebangeni elingaba ngu-0.5…2.5 ms.
Ukwengeza, isimo ekufakweni kwe-SW sinquma ukuthi iyiphi i-potentiometer (R1 noma i-R2) ezonquma ivolumu.tage okokufaka kwesiguquli. Lokhu kuvumela i-servo ukuthi ilawulwe ezifundeni ezimbili ngokusebenzisa okokufaka kwe-SW noma ububanzi obugcwele ngokushintsha indawo yama-potentiometers.

Ukuhlanganisa nokuqalisa
Umshini wahlanganiswa ebhodini lesifunda eliphrintiwe, umdwebo walo womhlangano oboniswe kuMdwebo 2. Umhlangano awudingi incazelo ebanzi, nokho, kufanele kuqashelwe kancane lapho kuhlanganiswa izinto eziphikisayo u-R3…R7. Lawa ama-SMD resistors, adayiswa ngakolunye uhlangothi lwebhodi.

Lolu phawu lusho ukuthi ungawulahli umkhiqizo wakho nomunye udoti wasendlini.
Esikhundleni salokho, kufanele uvikele impilo yomuntu kanye nendawo ezungezile ngokunikeza okokusebenza kwakho kukadoti endaweni eqokiwe yokuqoqa ukuze kugaywe kabusha izinto ezilahlwayo zikagesi neze-elekthronikhi.
I-AVT SPV iyaligodla ilungelo lokwenza izinguquko ngaphandle kwesaziso sangaphambili. Ukuhlanganisa nokuxhumeka kocingo okungahambisani nezinkomba ezingaphakathi kwemiyalelo, ukuguqulwa okungahleliwe kwezingxenye nanoma yikuphi ukuguqulwa kwesakhiwo kungabangela ukulimala ocingweni futhi kudalule abasebenzisi ekulimaleni. Esimeni esinjalo, umkhiqizi nabameleli bakhe abagunyaziwe ngeke babophezeleke kunoma yimuphi umonakalo ovela ngokuqondile noma ngokungaqondile ngenxa yokusebenzisa noma ukungasebenzi kahle komkhiqizo.
Amakhithi e-DIY enzelwe izinjongo zemfundo nemiboniso kuphela. Azihloselwe ukusetshenziswa ezinhlelweni zentengiso. Uma zisetshenziswa ezinhlelweni ezinjalo, umthengi uthatha wonke umthwalo wemfanelo wokuqinisekisa ukuthobela yonke imithethonqubo.
