Kodi sensa ya galimoto ndi chiyani?
Ma sensor a Youdaoplaceholder0 Ma sensor a magalimoto ndi zida zolowera mu kompyuta yamagalimoto, zomwe zimagwiritsidwa ntchito kusintha zambiri zosiyanasiyana za momwe galimoto imagwirira ntchito (monga liwiro la galimoto, kutentha, momwe injini ilili, ndi zina zotero) kukhala zizindikiro zamagetsi ndikuzitumiza ku unit yowongolera zamagetsi (ECU) kuti injini igwire bwino ntchito, kuwongolera chitetezo komanso kupanga zisankho mwanzeru. Ntchito yayikulu ya ndikuwonetsetsa kuti magalimoto akuyenda bwino, motetezeka komanso mosawononga chilengedwe. Magalimoto amakono amatha kukhala ndi masensa pafupifupi zana mpaka mazana awiri, omwe amaphimba mphamvu, chassis, thupi ndi machitidwe owonera chilengedwe.
Youdaoplaceholder0 Tanthauzo ndi ntchito zazikulu
Monga "mapeto a mitsempha" ya makina owongolera zamagetsi, masensa a magalimoto amawunika magawo akuthupi kapena a mankhwala (monga kutentha, kuthamanga, liwiro lozungulira, ndi kuchuluka kwa mpweya) nthawi yeniyeni ndikusintha ma signali osakhala amagetsi kukhala ma signali amagetsi kuti apange zisankho pa ECU. Mwachitsanzo, masensa oyendera mpweya amawunika kuchuluka kwa mpweya kuti akonze kuchuluka kwa mafuta olowetsedwa, ndipo masensa a nayitrogeni-oxygen amawunika kuchuluka kwa NOx mu mpweya wotulutsa utsi kuti awonjezere mphamvu yoyeretsa mpweya. Ntchito zake zazikulu ndi izi:
Youdaoplaceholder0 Kuyang'anira momwe ntchito ikuyendera : Sonkhanitsani deta monga liwiro la injini, liwiro la galimoto, ndi kuthamanga kwa mafuta kuti muwonetsetse kuti injiniyo ili bwino kwambiri.
Youdaoplaceholder0 control optimization : Mwa kusintha mpweya woipa, jakisoni wa mafuta ndi makina oletsa mabuleki kudzera mu mayankho a nthawi yeniyeni, monga makina a SCR kusintha mosinthasintha kuchuluka kwa jakisoni wa urea kutengera deta ya sensa ya nayitrogeni-oxygen, mphamvu yoyeretsa mpweya wotuluka imawonjezeka ndi zoposa 60%.
Youdaoplaceholder0 Chitetezo ndi matenda : Yambitsani alamu ya OBD system kapena lowani munjira yotetezera (monga kuchepetsa mphamvu ya injini) kuti vuto lisakule; Makina a ABS ndi ESP amadalira deta ya sensa ya liwiro la mawilo kuti aletse kutsekedwa kwa mawilo.
Zigawo zoyambira za ndi
Masensa nthawi zambiri amakhala ndi magawo atatu:
Chinthu chodziwika bwino cha Youdaoplaceholder0 : Chimayankha mwachindunji kuchuluka komwe kwayesedwa (monga kusintha kwa kutentha), ndipo chimatulutsa chizindikiro chosakhala chamagetsi.
Chinthu chosinthira cha Youdaoplaceholder0 : chimasintha zizindikiro zosakhala zamagetsi kukhala magawo amagetsi (monga kusintha kwa kukana ndi capacitance).
Dongosolo loyezera la Youdaoplaceholder0 : Limakonza zizindikiro zamagetsi kukhala magetsi oyezeka (voltage, current) kuti agwiritsidwe ntchito ndi ECU.
Mtundu waukulu wa ndi
Malinga ndi mfundo yogwirira ntchito komanso momwe amagwiritsidwira ntchito, masensa amagalimoto amatha kugawidwa m'magulu otsatirawa:
Youdaoplaceholder0 yagawidwa m'magulu malinga ndi kuchuluka kwa thupi:
Zosewerera kutentha (monga zosewerera kutentha kwa madzi ndi zosewerera kutentha kwa mpweya wolowa).
Zosewerera kuthamanga (monga zosewerera kuthamanga kwa mafuta, zosewerera kuthamanga kwa matayala).
Zosewerera mpweya (monga zosewerera mpweya, zosewerera NOx).
Masensa othamanga ndi malo (monga masensa othamanga ndi mawilo, masensa othamanga ndi crankshaft).
Youdaoplaceholder0 yagawidwa motsatira mfundo yogwirira ntchito :
Mtundu wotsutsa (monga sensa ya kutentha kwa thermistor).
Capacitive (monga masensa amadzimadzi).
Mtundu wa Photoelectric (monga sensa yowunikira).
Zosensa za inertial (monga accelerometers, gyroscopes).
Youdaoplaceholder0 yagawidwa ndi chizindikiro chotulutsa :
Sensa ya analogi (chizindikiro chamagetsi chopitilira kutulutsa).
Masensa a digito (ma pulse otulutsa kapena ma code).
Sensa ya mtundu wa switch (chizindikiro chotulutsa "choyatsa/chozimitsa").
Masensa a magalimoto ndi omwe amazindikira magalimoto kwambiri. Mwa kusintha magawo a makina kukhala zizindikiro zamagetsi, amaonetsetsa kuti injini ikugwira ntchito bwino, amawonjezera chitetezo cha galimoto komanso amakonza bwino magwiridwe antchito onse a galimoto.
Tanthauzo loyambira ndi mfundo yogwirira ntchito ya
Masensa a magalimoto ndi zida zolowera m'makompyuta omwe ali m'bwalo. Amazindikira kuchuluka kwa zinthu monga kutentha, kupanikizika ndi liwiro lozungulira kudzera muzinthu zofunikira, kenako amawasintha kukhala zizindikiro zamagetsi pogwiritsa ntchito zigawo zosinthira ndikuzitumiza ku ECU (Electronic Control Unit). Pomaliza, kutulutsa deta kokhazikika kumachitika kudzera mu ma circuits oyezera. Njira yosinthira chizindikiro iyi imalola galimoto kuyang'anira momwe ikugwira ntchito nthawi yeniyeni ndikusintha njira yake yowongolera yokha.
Youdaoplaceholder0 Core functional dimension
Dongosolo lowongolera injini la Youdaoplaceholder0
Youdaoplaceholder0 air-fuel ratio optimization : Sensa ya okosijeni imayang'anira kuchuluka kwa okosijeni mu mpweya wotulutsa utsi ndipo, mogwirizana ndi sensa ya kayendedwe ka mpweya, imakwaniritsa kuwongolera kotsekedwa kwa kuchuluka kwa mafuta olowetsedwa.
Youdaoplaceholder0 Kuletsa kugogoda : Sensa yogogoda imazindikira kugwedezeka kwa injini kosazolowereka, ndipo ECU imasintha yokha Angle yoyatsira moto.
Youdaoplaceholder0 temperature control : Sensor ya kutentha kwa madzi imalumikizidwa ndi makina ozizira kuti zitsimikizire kuti kutentha kwa injini kumasungidwa mkati mwa 85-95℃.
Dongosolo la chitsimikizo cha chitetezo cha Youdaoplaceholder0
Dongosolo la ABS limadalira masensa othamanga ndi mawilo kuti awerengere chiŵerengero cha kutsetsereka nthawi yeniyeni kuti apewe kutsekeka kwa mabuleki.
Dongosolo la airbag limazindikira kusintha kwadzidzidzi kwa liwiro kudzera mu masensa ogundana ndipo limayambitsa mayankho a millisecond.
Chojambulira mphamvu ya matayala chimayang'anira momwe matayala alili osayenera kuti achepetse chiopsezo cha kuphulika.
Youdaoplaceholder0 Kupititsa patsogolo luso loyendetsa galimoto
Sensa yolumikizira throttle imakonza momwe throttle imayankhira bwino komanso imachepetsa kugwedezeka kwa magiya.
Dongosolo loyimitsa limasintha mphamvu ya damping coefficient kudzera mu sensa yofulumizitsa kuti igwirizane ndi zovuta za pamsewu.
Chowunikira cha chilengedwe chimalumikizidwa ndi makina owunikira okha kuti chiwongolere kuwoneka bwino panthawi yoyendetsa galimoto usiku.
Ngati mukufuna kudziwa zambiri, pitirizani kuwerenga nkhani zina patsamba lino!
Chonde tiimbireni foni ngati mukufuna zinthu zotere.
