PHY yog lub hnub qub nce siab hauv cov ntawv thov hauv tsheb (xws li T-BOX) rau kev xa xov hluav taws xob ceev, thaum CAN tseem yog ib tus tswv cuab tseem ceeb rau qis-ceev teeb liab kis tau tus mob.Lub T-BOX ntawm lub neej yav tom ntej feem ntau yuav xav tau kev tso saib tsheb ID, roj noj, mais, trajectory, tsheb mob (qhov rooj thiab qhov rais teeb, roj, dej thiab hluav taws xob, idle speed, thiab lwm yam), ceev, qhov chaw, tsheb yam ntxwv , tsheb configuration, thiab lwm yam nyob rau hauv lub tsheb network thiab mobile tsheb network, thiab cov kuj tsis tshua muaj-ceev cov ntaub ntawv kis tau tus mob yog cia siab rau lub ntsiab cim ntawm tsab xov xwm no, CAN.

Lub tsheb npav CAN tau qhia los ntawm Bosch hauv Tebchaws Yelemees hauv xyoo 1980s thiab tau dhau los ua qhov tseem ceeb thiab tseem ceeb ntawm lub tsheb.Txhawm rau ua kom tau raws li qhov sib txawv ntawm cov tshuab hauv tsheb, lub tsheb npav CAN tau muab faib ua kev kub ceev CAN thiab qis-ceev CAN.Kev kub ceev CAN feem ntau yog siv rau kev tswj cov tshuab hluav taws xob uas xav tau kev ua haujlwm siab hauv lub sijhawm, xws li cov cav, tsis siv neeg kis, thiab cov twj paj nruag.Tsawg-ceev CAN feem ntau yog siv rau kev tswj hwm kev nplij siab thiab lub cev lub cev uas yuav tsum tau ua haujlwm tsawg dua lub sijhawm, xws li kev tswj cua txias, hloov lub rooj zaum, qhov rais lifting, thiab lwm yam.Hauv tsab xov xwm no, peb yuav tsom mus rau high-speed CAN.

Txawm hais tias CAN yog ib qho kev paub tab heev, nws tseem ntsib cov teeb meem hauv kev siv tsheb.Hauv daim ntawv no, peb yuav saib qee qhov kev sib tw CAN tab tom ntsib thiab qhia txog cov thev naus laus zis cuam tshuam los daws lawv.Thaum kawg, qhov zoo ntawm TI's CAN daim ntawv thov thiab nws cov khoom "hardcore" yuav tau piav qhia kom ntxaws.

Sib tw ib qho: EMI kev ua tau zoo ua kom zoo dua

Raws li qhov ceev ntawm cov khoom siv hluav taws xob hauv tsheb nce txhua xyoo, electromagnetic compatibility (EMC) ntawm cov tsheb sib txuas tau xav tau ntau dua, vim tias thaum tag nrho cov khoom sib xyaw ua ke hauv tib lub cev, nws yog ib qho tseem ceeb kom ntseeg tau tias cov subsystems ua haujlwm raws li qhov xav tau. , txawm nyob rau hauv lub ntsej muag ntawm lub suab nrov ib puag ncig.Ib qho ntawm cov teeb meem loj uas tau ntsib los ntawm CAN yog qhov ntau tshaj ntawm kev ua emissions los ntawm hom suab nrov.

Qhov zoo tshaj plaws, CAN siv qhov sib txawv sib kis sib kis los tiv thaiv cov suab nrov sab nraud txuas.Hauv kev xyaum, txawm li cas los xij, CAN transceivers tsis yog qhov zoo tagnrho thiab txawm tias me ntsis asymmetry ntawm CANH thiab CANL tuaj yeem tsim cov teeb liab sib txawv, uas ua rau cov hom kev sib xyaw ntawm CAN (piv txwv li qhov nruab nrab ntawm CANH thiab CANL) yuav tsum tsis tu ncua. DC tivthaiv thiab ua cov ntaub ntawv-nyob ntawm lub suab nrov.Muaj ob hom kev tsis sib haum xeeb uas ua rau lub suab nrov no: lub suab nrov tsawg zaus tshwm sim los ntawm kev tsis sib haum xeeb ntawm lub xeev khov kho hom hom nyob rau hauv lub xeev tseem ceeb thiab recessive, uas muaj ntau zaus ntawm cov qauv suab nrov thiab tshwm raws li ib tug series ntawm uniformly. spaced discrete spectral kab;thiab lub suab nrov ntau zaus tshwm sim los ntawm lub sijhawm sib txawv ntawm qhov kev hloov pauv ntawm qhov tseem ceeb thiab qhov tsis zoo ntawm CANH thiab CANL, uas muaj cov pulses luv thiab cuam tshuam los ntawm cov ntaub ntawv ntug jumps.Daim duab 1 hauv qab no qhia txog ib qho piv txwv ntawm CAN transceiver tso zis ntau hom suab nrov.Dub (channel 1) yog CANH, ntshav (channel 2) yog CANL thiab ntsuab qhia cov lej ntawm CANH thiab CANL, tus nqi ntawm qhov sib npaug ntawm ob npaug ntawm cov hom hluav taws xob sib txawv ntawm lub sijhawm.
