Yintoni CAN-Bus, yaye yintoni na ukuba?

Okwangoku, phantse imoto zonke mihla linabasebenzi iikhompyutha kwi-Yodi, iinkqubo ABS, EBD, iifestile amandla kunye nezinye izixhobo ezininzi ze-elektroniki. Ngoku, le ndlela uyakwazi ukulawula ngoomatshini kuphela, kodwa iinkqubo anomoya kunye hydraulic. Nditsho injini akakwazi ukwenza ngaphandle elektroniki. It is a isixhobo ezikhethekileyo - CAN-bus. Yiloo nto kuxoxwa namhlanje.

Imbali ingenzeka

Ingcamango CAN-bhasi ukuvela 80s kwinkulungwane yokugqibela. Emva koko inkampani eyaziwayo-kakuhle isiJamani "Bosch" ngentsebenziswano eqinile "Intel" liphuhlise isixhobo entsha digital ukugqithisa data, ekuthiwa Controller Area Network.

Into ungenza ntoni?

Le ibhasi uqhagamshelo zonke nabenzi boluvo, kwaye lulawula iibhloko ukuba kwisithuthi. Ndingakwazi aqhagamshelwe immoblayzerom, inkqubo SRS, ESP, iyunithi yolawulo injini ngekhompyutha, transmission, kwaye nkqu airbag. Ukongeza, i-waseTire nabo kunye nabenzi boluvo ukunqunyanyiswa, inkqubo yokuvala central kunye nolawulo kwemozulu. Zonke ezi ndlela ezidibene kwindlela ngokupheleleyo-kabini kunye izinga data ukuya ku-1 Mbit / s.

CAN-bus: Inkcazelo kunye iimpawu device

Kusebenziso konke, le ndlela iquka ingcingo nje ezimbini chip enye. Ngaphambili, ukudibanisa zonke boluvo ifumana ngamashumi CAN-bus iiplagi. Ukuba iminyaka engama-80 ngenxa ngamnye ngaphandle nokudlulisela uphawu olunye kuphela, ngoko ke eli xabiso ifikelela amakhulu.

NGABA tire mihla ungachazwa ukuba unawo umsebenzi kokuxhuma ukuya ngeselula. Electronic iqhosha ring, owenza umsebenzi weqhosha ucinezelo, nazo sidityaniswe kwi yunithi yaye ufumane ingcaciso evela unit control injini.

Kubalulekile ukuba esi sixhobo ukuze ukuchaza ingxaki ekusebenzeni izixhobo umatshini kwaye kwezinye iimeko nya. Cishe alichaphazeleki yi kweziphazamiso, kwaye abafowunelwa elungileyo usambathisa. CAN-bus yi algorithm inzima kakhulu. Data ethunyelwayo ngawo eyodlula, nangoko similise imifanekiso. Le ngcaciso imfutshane njengesikhokelo-wire 2 isibini coil. Kukho kwakhona eziveliswa ifayibha, kodwa ngaphantsi ngempumelelo ukusebenza, ke ngoko, hayi kangako eqhelekileyo wokuqala ukhetho. Mancane ukuhlangabezana CAN-ibhasi, nto leyo edlulisela ulwazi nge kanomathotholo okanye reyi infrared.

Ukusebenza kunye nokusebenza

Ukuphucula indlela yokusebenza kule fowuni, abenzi badla yayinqamlela ubude macingo. Ukuba ubude elipheleleyo ibhasi iya kuba kwiimitha ngaphantsi kwe-10, umlinganiselo ingcaciso iya kwandisa ukuya megabits 2 ngomzuzwana. Ngokuqhelekileyo le ndlela ngesantya 64 lokudlulisa kunye nabenzi boluvo elektroniki izilawuli. Ukuba ibhasi oludityaniswe inani elikhulu lwezixhobo kudala iziphaluka eziliqela ngokufumana kunye yokudlulisela ulwazi.

Ukuba CAN-Bus iza kuphuhliswa ngakumbi, mhlawumbi sekumbovu efakwe ngokupheleleyo kuzo zonke iimoto kunye neelori, kuquka ukuba zasekhaya.
