Umsebenzi wokuvikela ukuvikela ukukhishwa ngokweqile kweshubhu lamandla okushintsha kanye nokuphakelwa kwamandla kusilawuli, futhi lapho ibhayisikili lezinyawo ezintathu zokungcebeleka labadala lisebenza, isekethe izoyithatha ngokuya ngesignali yempendulo uma kukhona amaphutha athile noma ukungasebenzi kahle okungenzeka. dala umonakalo kanye namanye amaphutha.Vikela.Imisebenzi eyisisekelo yokuvikela kanye nemisebenzi eyandisiwe yezimoto zikagesi zabantu abadala imi kanje:
1. Ukubhuleka amandla
Izibambo ezimbili ze-caliper brake ku-handlebar ye-leisure tricycle yabantu abadala zonke zifakwe amaswishi okuxhumana.Uma ubhuleka, iswishi iyaphushwa futhi ivalwe noma inqanyulwe, ngaleyo ndlela kushintshe isimo sokushintsha sangempela.Lolu shintsho lwakha isignali futhi luyithumele kusekethe yokulawula, futhi isekethe ikhipha umyalelo ngokohlelo olusethiwe ukuze kunqanyulwe ngokushesha i-base drive current, kunqanyulwe amandla, futhi kumiswe ukunikeza amandla.Ngakho-ke, akuvikeli kuphela i-tube yamandla ngokwayo, kodwa futhi ivikela i-motor endala, futhi ivimbela ukuchithwa kwamandla kagesi.
2. Ukuvikelwa kwe-Undervoltage
Lokhu kubhekisela ku-voltage kagesi.Esigabeni sokugcina sokukhipha, ngaphansi komthwalo, i-voltage yokuhlinzeka amandla iseduze "ne-voltage yokuphela kokukhishwa", futhi iphaneli yokulawula (noma iphaneli yokubonisa insimbi) izobonisa ukuthi ibhethri ayanele, okuzodonsa ukunaka. yomgibeli futhi ahlele uhambo lwakhe.Lapho i-voltage yokuphakela amandla isifinyelele ekupheleni kokukhishwa, i-voltage sampling resistor izonikeza ulwazi lwe-shunt kusiqhathanisi, futhi isekethe yokuvikela izokhipha imiyalelo ngokohlelo olusethiwe ukuze inqamule yamanje ukuze kuvikelwe amadivaysi kagesi namandla.
3. Ukuvikelwa kwamanje
Ukweqa umkhawulo wamanje kungase kubangele umonakalo ochungechungeni lwezingxenye zenjini nesekhethi, noma ngisho nokushiswa, okufanele kugwenywe ngokuphelele.Kumjikelezo wokulawula, lolu hlobo lomsebenzi wokuvikela ngokweqile kufanele lunikezwe, futhi lwamanje luzonqanyulwa ngemva kokulibaziseka okuthile lapho kwenzeka i-overcurrent.
4. Ukuvikelwa kokugcwala ngokweqile
Ukuvikelwa kokulayisha ngokweqile kuyafana nokuvikelwa kwe-overcurrent, futhi umthwalo oweqa umkhawulo nakanjani uzobangela ukuthi okwamanje kweqe umkhawulo.Umthamo womthwalo ukhonjiswe ngokuqondile kumanyuwali wezimoto zikagesi, kodwa abanye abagibeli bangalinaki leli phuzu, noma bawulayisha ngokweqile ngenhloso ngomqondo wokuzama ukuwuzama.Uma ungekho umsebenzi onjalo wokuvikela, angeke ubangele umonakalo kunoma yisiphi isixhumanisi, kodwa ishubhu yamandla eshintshayo ingeyokuqala ethwala kanzima.Uma nje elinye lamashubhu amandla esilawuli se-brushless lisashiswa, lizoba ngumthombo wamandla wezigaba ezimbili, futhi injini endala izoba buthaka lapho isebenza.Umhambi angakwazi ngokushesha ukuzwa ukushaya kwenhliziyo okungavamile;uma eqhubeka nokugibela, khona-ke amashubhu wamandla wesibili nowesithathu azoshiswa.Uma i-tube yamandla ezigaba ezimbili ingasebenzi, injini izoyeka ukusebenza, futhi i-brush motor izolahlekelwa umsebenzi wayo wokulawula.Ngakho-ke, i-overcurrent ebangelwa ukulayisha ngokweqile kuyingozi kakhulu.Kodwa inqobo nje uma kukhona ukuvikeleka okungaphezu kwamanje, umjikelezo uzonqamula ngokuzenzakalelayo ukunikezwa kwamandla ngemva kokuba umthwalo udlule umkhawulo, futhi uchungechunge lwemiphumela ebangelwa ukulayisha ngokweqile lungagwenywa.
5. Ukuvikelwa okungaphansi kwesivinini
Iseyingxenye yesigaba sokuvikelwa kwe-overcurrent, futhi isethelwe isistimu yokulawula i-brushless ngaphandle komsebenzi wokuqala ngesivinini esingu-0.
6. Ukuvikelwa komkhawulo wesivinini
Iwuhlelo oluhlukile lokulawula ukwakheka kwamabhayisikili kagesi asiza abantu abadala.Uma isivinini semoto sidlula inani elithile elinqunywe kusengaphambili, isekethe iyayeka ukunikeza amandla futhi ayinikezi usizo.Ezimotweni zikagesi zikagesi zabantu abadala, isivinini esihlanganisiwe singama-20km/h, futhi isivinini esilinganiselwe kanye nesifunda sokulawula sesivele simisiwe lapho imoto yemoto iklanywa.Izimoto ezisebenza ngogesi ezindala zikwazi ukugijima kuphela ngesivinini esingeqile kuleli jubane.Isikhundla somlawuli asithinti ukusebenza, ikakhulukazi kuncike enjongweni yomklami.Kodwa kunezimiso eziningana: (1) Lapho ukuhlinzwa kuvunyelwe;(2) Uma isakhiwo sesisonke sivunyelwe;(3) Uma isakhiwo somugqa sidingeka;(4) Lapho kudingeka izinsiza ezisekelayo.
Isiginali yokulawula isivinini esiphumayo iyisiginali ye-voltage, futhi i-voltage ephumayo ye-turntable yaseHholo incike emandleni enkambu kazibuthe ezungeze isici seHholo.Ukuphendula isibambo kushintsha amandla kazibuthe azungeze into Yehholo, ephinde iguqule ugesi ophumayo wesibambo seHholo.Bese ufaka le-voltage kusilawuli, futhi isilawuli senza i-PWM yobubanzi be-pulse modulation ngokuvumelana nobukhulu balesi siginali.Ngakho-ke, isilinganiso sokuvala ishubhu yamandla silawulwa ukulawula isivinini semoto.
