I-brake pedal anti-lock braking system (antilockbrakesystem) yemoto uma ihlangene ibizwa nge-ABS. Umsebenzi uwukulawula amandla esistimu yokubhuleka yesistimu yokubhuleka lapho imoto ibhuleka, ukuze amasondo angavalwa ngamasondo futhi abe sesimweni sokugingqika nokushelela (izinga lokuhamba licishe libe ngu-20%), ukuze kuqinisekiswe ukunamathela kwamasondo nomhlabathi. Amandla efindo akunani eliphezulu.
Umsebenzi wenzwa yesivinini samasondo ku-ABS ukukala ngokunembile isilinganiso sokudluliswa kwamasondo emoto. Inzwa yesivinini sesondo ithola isignali yefrikhwensi (isiginali yesilinganiso sokudlulisa) yokuzungezisa kwesondo ngalinye, bese ithumela lesi siginali kukhompyutha ye-ABS. Uma isivinini siqinisekisiwe kunani elilinganiselwe, iphedi yebhuleki ephuthumayo ibhuleka isistimu bese isistimu ye-ABS iqala ukusebenza. Uma ikhompuyutha ye-ABS ilawula isondo ukuze lixege isikhashana, inzwa yejubane lesondo ithumela isignali yesikhashana ebona ukuzungeza kwesondo lisuka ekubhulekini liye ku-ABS electronic computer, ukuze i-ABS ilawule i-brake pad ukuze ifinyelele ibanga elingcono kakhulu lokubhuleka. Izinhlobonhlobo zezinzwa zesivinini samasondo ikakhulukazi zihlanganisa izinzwa zejubane lesondo lamagnetoelectric kanye nezinzwa zejubane lesondo lohlobo lweHall.
Inzwa yejubane lesondo le-magnetoelectric iklanywe ngokusebenzisa uhlelo lomphumela kazibuthe lwamanje kagesi. Ilula ngesakhiwo, intengo ephansi, ayiwesabi amabala odaka, futhi ayidingi imishini yokusabalalisa amandla, futhi isetshenziswa kakhulu kuma-ABS anti-lock braking systems. Kodwa kukhona futhi okunye okungalungile, okufana nesici se-phase-frequency asiphezulu, lapho isivinini siphezulu kakhulu, isici se-phase-frequency yenzwa asikwazi ukuqhubeka, okungaholela kalula kumasignali amanga. Kuphinde kube nekhono eliphansi lokumelana nokuphazanyiswa yi-electromagnetic. I-waveform elinganiswa ngokunembile nge-analog oscilloscope isesimweni se-sine function wave, futhi ukuphakama kwesilinganiso sokudluliswa kwesondo, sikhulu isignali ephumayo esebenza inani lokuqina kwamandla kagesi.
Inzwa yejubane lesondo lohlobo lweHholo yenziwa ngokusebenzisa umqondo oyisisekelo womphumela weHholo. Isignali yayo yokuphumayo ayilinyazwa kalula isivinini se-voltage evamile kanye nenani lamandla. Inezici zokuvama kwesigaba esiphakeme kanye nekhono eliqinile lokuphazanyiswa kwegagasi le-anti-electromagnetic, kodwa kufanele ibe nemishini yokusabalalisa amandla. Bafo, ngakho-ke inzwa yenza izilinganiso ezinembile zesibonelo:
Ekuqaleni, xhuma i-BNC kukhebuli yekhanda likabhanana endaweni yokuphepha ye-analog oscilloscope. Ikhanda elibomvu lixhunywe kwinaliti njengezinga elihle, futhi umugqa wesignali wenzwa uxhunyiwe. Ikhanda elimnyama le-acne lingaxhunywa kusiqeshana se-alligator noma inaliti njengesistimu yokumisa phansi.
Vula ibha yamathuluzi ephuma ngokuphepha ye-analog oscilloscope, setha isilinganiso sokulahlekelwa kokuphuma ngokuphepha sibe ngu-1X, lungisa igiya lemoto elime mpo libe ngu-1V/div, bese ufaka isisekelo sesikhathi sibe ngu-10ms, bese ungakwazi ukusilungisa ngokuya ngemininingwane.
Njengoba inzwa yejubane lesondo lohlobo lweHholo inomshini wokusabalalisa amandla wesekethe eshintshwayo, kufanele kube khona amandla alawulwayo e-DC acishe abe ngu-11-12V ukuze abuke i-waveform ngalesi sikhathi.
Phakamisa imoto ngojeke, phendula isondo, futhi ulinganise ngokunembile i-waveform yesignali yenzwa nge-analog oscilloscope yezimoto.
Izinzwa zomphumela wehholo zihlanganisa uzibuthe unomphela noma isekethe evaliwe enenkambu ye-electromagnetic cishe icishwe ngokuphelele, i-impeller yamagnetic fan fan ijika igebe phakathi kukazibuthe nenkundla kazibuthe, futhi ayilimazi lapho ibhokisi lethiphu ku-impeller ye-fan livumela amandla kazibuthe Lapho umhlabathi udluliselwa kunzwa yomphumela weHholo, insimu kazibuthe iyaphazamiseka (ngenxa yokuthi i-blade idlula inzwa), i-fan impeller ivumela isisekelo senkundla kazibuthe kanye nengqikithi yenkundla kazibuthe yomoya lapho ibhokisi lokwazisa livulwa futhi livaliwe, okuholela kumphumela weHholo. Inzwa yomphumela ixhunyiwe futhi ivaliwe njengokushintsha kwamandla, yingakho ezinye izinkampani zezimoto zibhekisela kunzwa yomphumela wehholo kanye nezinye izinto zikagesi ezifanayo njenge-switch power yasehholo, le divayisi yomshini empeleni iyi-voltage ephezulu ye-Switchgear. Ngakho-ke, i-waveform yesiginali yenzwa yomphumela weHholo empeleni ishayela ngemva kwenye, okungukuthi, i-waveform.
Ukushesha kwesilinganiso sokuhambisa isondo, imvamisa ye-waveform yesiginali iba ngokushesha, kepha i-AC yamanje yokuxhumana kwayo ihlala ifana, konke kusuka ku-0V kuye ku-1V. Ukwehlisa isivinini sokujikeleza kwesondo, ungabona ukuthi imvamisa ye-waveform yesiginali nayo iyehla.
Uma inzwa ye-ABS yesibonisi sedijithali inokuphuma kukagesi okujwayelekile okungu-0 volt kuphela, kufanele ihlolwe kuqala ukuze kutholwe ukuthi ingabe inawo yini ugesi oshintshayo wokuphakela isekethe. Bese kunqunywa ukuthi ingabe imvamisa yesiginali yenzwa ilandela eduze isilinganiso sesondo, ngaphandle kwalokho kubonisa inkinga evamile.
