Kwimishini yokwakha, izixhobo zezolimo zanamhlanje, iibhasi zabakhweli kunye namanye amacandelo, ibhasi ye-CAN isebenza njengomthombo wonxibelelwano oyintloko wenkqubo epheleleyo yokulawula izithuthi nge-elektroniki, enoxanduva lokuhambisa idatha kunye nokusebenzisana phakathi kwenjini, i-gearbox kunye nee-sensors zangaphandle. Njengesixhobo esiphambili sokusebenzisana kwabantu kunye nomatshini kunye nesiphelo sokuqokelelwa kwedatha kwikhabhathi, inani kunye nokusebenza kweetshaneli ze-CAN kwiithebhulethi eziqinileyo ezixhonywe kwizithuthi zimisela ngokuthe ngqo ukuthembeka kokuqokelelwa kwedatha yesithuthi kunye nokuzinza konxibelelwano. Eli nqaku liza kuchaza umahluko ophambili phakathi kwe-CAN enye kunye ne-CAN ezimbini, kunye neendawo zazo eziphambili zokusetyenziswa, ukunceda abathengi baphephe imigibe yokuthengwa efana ne-CAN eyenziwe ngesoftware kunye neendlela ezandisiweyo zesango ezithengiswa ngobuxoki njengezixhobo ze-CAN ezininzi.
Iitshaneli zeHardware zeCAN ezizimeleyo zeNative vs. iGateway-Expanded / iSoftware-Simulated CAN
Eyona ndlela iphambili yokugweba amandla e-CAN kwithebhulethi eqinileyo kukuba ingaba i-mainboard SoC idibanisa ii-peripherals zolawulo lwe-CAN zasekhaya ezizinikeleyo. Iitshaneli ezandisiweyo nge-CAN eyenziwe ngesoftware okanye ii-USB/Ethernet zangaphandle ze-CAN azinakulingana nokusebenza kwehardware yasekhaya, kwaye izikhewu ezisisiseko zehardware phakathi kwezisombululo ezimbini azinakubuyiselwa ngokulungiswa kwesoftware.
Uqwalaselo oluQhelekileyo lweHardware yeNdalo I-CAN
Itshaneli nganye ixhotyiswe ngezixhobo zehardware ezikhethekileyo: isilawuli se-CAN esizimeleyo, i-transceiver ye-CAN ekhawulezayo ezimeleyo, i-resistor ehambelana nesiphelo esizimeleyo, umbane ohlukanisiweyo kunye nesekethe yokwahlukanisa yedijithali, kunye neTVS yokukhusela ukuntywila okuzimeleyo. Umbane, iisekethe zomhlaba kunye nesignali zazo zonke iitshaneli zahlulwe ngokupheleleyo ngombane. Iisekethe ezimfutshane, ukukhutshwa kwe-electrostatic okanye ukuphazamiseka kokuntywila kwitshaneli enye akuyi kusasazeka kwenye itshaneli, kususa umngcipheko wokusasazeka kwempazamo kwiindawo zenethiwekhi.
Iingxaki Eziphambili ze-Gateway-Expanded / Software-Simulated CAN
IiGateways zizixhobo zokudlulisela iprotocol. Zonke imiyalezo ye-CAN zabelana ngezixhobo ezifanayo zokucubungula i-CPU kunye ne-single power domain ngaphandle kokwahlulwa kwehardware. Umthamo wedatha obekwe ngaphezulu ukusuka kwiinxalenye ezininzi zebhasi uyawonyusa kakhulu umthwalo we-CPU kwaye ungenise i-millisecond-level forwarding latency. Ukungaphumeleli kwesango kunokuphazamisa zonke iinxalenye zebhasi ezixhunyiwe ngaxeshanye, kwaye kwiimeko ezinzima kubangele ukuphazamiseka konxibelelwano lwe-ECU yesithuthi esipheleleyo. Ezo zisombululo azihlangabezani neemfuno zokhuseleko zezithuthi zokwakha, kwaye zilungele kuphela ukulungisa okwethutyana endaweni yokujonga rhoqo kweenqwelo-moya iiyure ezingama-24/7.
I-CAN enye (Imodeli yoBunzima bokungena)
Ixhotyiswe ngeseti enye kuphela yesilawuli se-CAN kunye ne-transceiver yetshaneli enye, exhasa uqhagamshelo kwicandelo elinye lebhasi. Kwizithuthi ezinezakhiwo ezininzi zebhasi, iintambo zocingo kufuneka zikhutshwe ngesandla kwaye ziqhagamshelwe kwakhona ukuze kutshintshwe ukufunyanwa kwedatha, okwenza ukufundwa okuhambelanayo kweemeko zokusebenza kwiinkqubo ezimbini ezizimeleyo kungenzeki. Xa inani elikhulu lee-nodes kunye nemithwalo yemiyalezo enzima ibhasini, izinga lomthwalo webhasi lidlula ngokulula umda womngcipheko we-70%, okubangela ukuxinana kwemiyalezo emgceni, ukulahleka kweepakethi rhoqo kunye nokunyuka okubukhali kokulibaziseka konxibelelwano. Ukubeka iliso kwimeko yesithuthi ngexesha langempela kunye nemisebenzi yokuxilonga enzulu ye-UDS ayinakusebenza ngaxeshanye; Ukukhanya kwe-ECU kunye nokusombulula iingxaki kufuna ukunqanyulwa kwekhonkco lokubeka iliso kwisithuthi kunye nokuphazamisa ukulayisha idatha yeenqwelo.I-Single CAN isebenza kuphela kwiimeko ezisisiseko eziquka uyilo lwebhasi yesithuthi esinye, iinkqubo zolawulo ze-elektroniki ezilula kunye neemfuno zokuchonga iimpazamo ezinzulu.
I-CAN ezimbini (Imodeli esemgangathweni ephambili)
Ibhodi enkulu idibanisa iiyunithi ezimbini zezixhobo ze-CAN ezizimeleyo ngokupheleleyo, ezizimeleyo ngombane. Ezi channels zimbini azikhuphisani ngezixhobo zezixhobo, zinokucwangciswa ngokwazo ngokwamanqanaba ahlukeneyo e-baud, kwaye zixhasa unxibelelwano oluhamba ngesantya esiphezulu olufikelela kwi-1 Mbps. Ukuqokelelwa kwedatha ye-dual-bus ehambelanayo, ukubeka esweni kunye nokuxilongwa kuyaxhaswa, kugubungela ngaphezulu kwe-90% yeemeko zokusebenza eziqhelekileyo kwizithuthi ezinzima, okwenza kube yindawo ephambili kumashishini oomatshini bokwakha, bempahla kunye nezolimo.
1. Ukuqokelelwa kwedatha yeebhasi ezimbini ezihambelanayo ukuze kufumaneke idatha epheleleyo yokusebenza:
Itshaneli 1 iqhagamshela kwibhasi yamandla ye-J1939 (injini, i-transmission, inkqubo yokuqhobosha), ngelixa itshaneli 2 iqhagamshela kwibhasi ye-hydraulic okanye ibhasi yokulawula umzimba. Abaqhubi banokubona imeko yokusebenza kwithebhulethi, kwaye iqonga lasemva liqokelela idatha yokusebenza ngexesha langempela ngaphandle kokutshintsha i-wiring harness okanye ukuqokelelwa kwedatha yokwabelana ngexesha.
2. Ukubeka esweni kunye nokuxilonga okufanayoNgconoUlondolozo:
Itshaneli 1 igcina ukulayisha imeko yesithuthi, ukusetyenziswa kwepetroli kunye nee-alamu zempazamo iiyure ezingama-24 ngosuku, iintsuku ezisixhenxe ngeveki ukuze kujongwe rhoqo iinqwelomoya. Itshaneli 2 isebenzisa ukuxilongwa kweempazamo ezinzulu ze-UDS kunye nenkqubo ye-ECU ekhanyayo ngaphandle kokuphazamisa ukujonga, nto leyo ephucula kakhulu ukusebenza kakuhle kokugcinwa kweenqwelomoya.
3. Ukuzahlula phakathi kweeBhasi zeMoto yoQoqo kunye neePeripherals ukuze kupheliswe ukuphazamiseka:
Iitshaneli ezinikezelweyo zahlula inkqubo yolawulo lwe-elektroniki yesithuthi kwizinto zangaphandle. Ukungasebenzi kakuhle okanye ukuphazamiseka kwe-overflow okuvela kwizinto zangaphandle kuhlala kuxhomekeke kwitshaneli enye kwaye akunakungena kwibhasi yamandla yokuqala, okuqinisekisa ukusebenza okuzinzileyo nokukhuselekileyo kwenkqubo yolawulo lwe-elektroniki yesithuthi.
Isikhokelo soKhetho olujoliswe kuko: Ulungelelwaniso olufanelekileyo lwe-CAN kwiimeko ezahlukeneyo zokusebenza
