Mu mashini z'ubwubatsi, ibikoresho bigezweho by'ubuhinzi, amagare y'abagenzi n'izindi nzego, bisi ya CAN ikora nk'inkingi y'itumanaho ry'ingenzi rya sisitemu yose igenzura imodoka, ishinzwe kohereza amakuru no gukoresha amabwiriza hagati ya moteri, boritike n'ibikoresho byo hanze. Nk'aho ari ho itumanaho ry'abantu n'imashini rihurira n'abantu n'uburyo bwo gukusanya amakuru muri kabine, umubare n'imikorere y'imiyoboro ya CAN ku bikoresho bikomeye biri ku modoka bigena neza uburyo amakuru y'imodoka ahora akusanywa n'uburyo itumanaho rihagaze. Iyi nkuru izasobanura itandukaniro riri hagati ya CAN imwe na CAN ebyiri, ndetse n'ahantu nyamukuru zikoreshwa, kugira ngo bifashe abakiriya kwirinda ingorane zikunze kugaragara mu kugura nka CAN ikoresha porogaramu n'imiyoboro yagutse yagurishijwe mu buryo butari bwo nk'ibikoresho bya CAN byinshi bisanzwe.
Imiyoboro ya mudasobwa ya CAN yigenga ugereranyije na Gateway-Expanded / Software-Simulated CAN
Igipimo cyonyine cyo gusuzuma ubushobozi bwa CAN bwa tablet ikomeye ni ukumenya niba SoC y’ibanze ihuza ibikoresho bya CAN byabugenewe. Imiyoboro yagutse binyuze muri CAN ikoresha porogaramu cyangwa USB/Ethernet CAN gateways zo hanze ntizishobora guhuza imikorere ya mudasobwa, kandi icyuho cy’ibikoresho hagati y’ibi bisubizo byombi ntigishobora guhindurwa na porogaramu.
Imiterere y'ibikoresho bisanzwe bya Native CAN
Buri muyoboro ufite ibikoresho byihariye: umuyoboro wigenga wa CAN, transceiver yigenga ya CAN yihuta, resistor yigenga ihuza terminal, amashanyarazi yihariye hamwe na circuit ya digitale isolation, na TVS yigenga irinda surge. Ingufu, imiyoboro yo hasi n'iy'ibimenyetso by'imiyoboro yose bishyirwa ukwabyo hakoreshejwe amashanyarazi. Imiyoboro migufi, imiyoboro ya electrostatic cyangwa interference y'umuyoboro umwe ntibizakwirakwira mu wundi muyoboro, bikuraho ibyago byo gukwirakwira kw'amakosa mu bice by'umuyoboro.
Ingaruka z'ingenzi za Gateway-Expanded / Software-Simulated CAN
Amarembo ni ibikoresho byo kohereza amakuru kuri protocole. Ubutumwa bwose bwa CAN busangiye umutungo umwe wo gutunganya CPU n'ingufu imwe nta gutandukanya ibikoresho. Ingano y'amakuru aturutse mu bice byinshi bya bisi yongera cyane umutwaro wa CPU kandi igatera gutinda ko kohereza amakuru kuri milisegonda. Ikosa ryo kwinjira mu marembo rishobora guhungabanya ibice byose bya bisi icyarimwe, kandi mu bihe bikomeye bigatera ikibazo cy'itumanaho rya ECU ry'imodoka yose. Ibisubizo nk'ibi ntibihura n'ibisabwa mu mutekano w'imodoka z'ubwubatsi, kandi bibereye gusa mu gukosora amakosa by'agateganyo aho gukurikirana amasaha 24/7.
ICYAMA KIMWE (Icyitegererezo cyoroheje cyo mu rwego rwo kwinjira)
Ifite itsinda rimwe gusa rya CAN controller na transceiver imwe, bifasha guhuza igice kimwe cya bisi. Ku binyabiziga bifite imiterere myinshi ya bisi, imiyoboro y'insinga igomba gukurwamo intoki no kongera guhuzwa kugira ngo ihindure amakuru, bigatuma gusoma imiterere y'imikorere y'ibinyabiziga bibiri byigenga bidashoboka. Iyo umubare munini w'amanode n'ubutumwa buremereye biri muri bisi, igipimo cy'imizigo ya bisi kirenga byoroshye 70% by'ibyago, bigatuma ubutumwa bucucika ku murongo, gutakaza amapaki rimwe na rimwe no kwiyongera gukomeye mu gutinda k'itumanaho. Gukurikirana imiterere y'imodoka mu gihe nyacyo no gusuzuma byimbitse UDS ntibishobora gukora icyarimwe; ECU flashing no gukemura ibibazo bisaba gusiba umurongo ugenzura imodoka no guhagarika kohereza amakuru y'imodoka.Isosiyete imwe ya CAN ikoreshwa gusa ku bintu by'ibanze birimo imiterere ya bisi imwe, sisitemu zoroshye zo kugenzura ikoranabuhanga ndetse n'ibisabwa kutagira ikibazo cy'ubujyakuzimu.
Imashini ebyiri zikoreshwa mu gupima (Icyitegererezo Gisanzwe)
Iyi mashini ihuza ibikoresho bibiri bya CAN byigenga kandi byigenga, byashyizwe mu buryo bw'amashanyarazi. Iyi miyoboro yombi ntabwo ihangana n'ibikoresho, ishobora gushyirwa mu buryo bwigenga hamwe n'ibipimo bitandukanye by'amashanyarazi, kandi igashyigikira itumanaho ryihuse kugeza kuri 1 Mbps. Gukusanya, gukurikirana no gusuzuma amakuru ajyanye na bisi ebyiri birashyigikiwe, bikubiyemo 90% by'imikorere isanzwe y'imodoka ziremereye, bigatuma iba igikoresho cy'ingenzi mu nganda z'ubwubatsi, imizigo n'imashini z'ubuhinzi.
1. Gukusanya amakuru ya bisi ebyiri zihurira hamwe kugira ngo amakuru yose akoreshwe agerweho:
Umuyoboro wa 1 uhuza na bisi ya J1939 (moteri, transmission, sisitemu yo gufunga feri), mu gihe Umuyoboro wa 2 uhuza na bisi ya hydraulic cyangwa bisi igenzura umubiri. Abakoresha bashobora kureba uko imikorere ihagaze kuri tablet, kandi urubuga rwa nyuma rukusanya amakuru y'imikorere mu gihe nyacyo nta guhinduranya insinga cyangwa gusangira amakuru.
2. Gukurikirana no gusuzuma indwara ku buryo bungana kuriBirutaGusana:
Channel 1 ikomeza gushyira ahagaragara imiterere y'imodoka amasaha 24/7, iminsi 7 mu cyumweru, aho imodoka zikoresha lisansi n'amakuru amenyesha impanuka kugira ngo ikomeze kugenzura ubwiherero bw'imodoka. Channel 2 ikora ubushakashatsi bw'ibibazo byimbitse bya UDS na gahunda ya ECU idahagarika igenzura, binongera cyane imikorere myiza y'ubwiherero bw'imodoka.
3. Gutandukanya bisi y'umwimerere n'ibice byayo kugira ngo hakurweho ikibazo:
Imiyoboro yihariye itandukanya sisitemu y’ibanze y’igenzura ry’ikoranabuhanga ry’ikinyabiziga n’iy’inyuma. Imikorere mibi cyangwa ukwivanga kw’ingufu z’inyuma biguma ku muyoboro umwe kandi ntibishobora kwinjira muri bisi y’ingufu ya mbere, biha icyizere cy’imikorere ihamye kandi itekanye y’isitemu yose y’igenzura ry’ikoranabuhanga ry’ikinyabiziga.
Inzira yo Guhitamo Intego: Imiterere myiza ya CAN ku Miterere Itandukanye y'Imikorere
1. Hitamo agasanduku kamwe kabigenewe:
Imodoka zoroshye zitwara ibikoresho, amakamyo mato yo mu ruganda n'amakarito yo gutwara ibintu; ikoreshwa risaba gusa aho imodoka iherereye, umuvuduko wayo n'ikoreshwa rya lisansi, nta kibazo cy'ikosa cyangwa ibikoresho by'ubuhinzi/hydraulic.
2. Hitamo CAN ebyiri kuri:
Imashini nto n'iziciriritse zicukura, imashini zitwara imizigo n'izizunguruka imihanda; amakamyo asanzwe aremereye, amakamyo y'ibitaka n'amabisi atwara abagenzi; amatraktori mato n'aciriritse n'imashini zisarura; gukurikirana buri gihe ubwikorezi bw'imodoka no gusuzuma ibikorwa byo kubungabunga imodoka.
Umwanzuro
Imiterere y'imiyoboro ya CAN bus ni ikimenyetso cy'ingenzi kigaragaza imiterere y'imikorere ya tableti zikomeye zishyizwe ku modoka, aho kuba parametero y'inyongera ku bushake. Guhitamo neza imiyoboro ya CAN hashingiwe ku mikorere byirinda ibibazo birimo kudahuza neza na sisitemu no kongera guhindurwa, bigatuma iba ihuriro rikomeye mu guhitamo ibikoresho by'ikoranabuhanga ku mishinga y'imodoka zikoresha ubwenge.
Urutonde rwuzuye rwa 3Rtablet rw'ibinini bikomeye bishyirwa ku modoka rukubiyemo ibipimo bya CAN imwe na CAN ebyiri zifite ingano ya ecran ya santimetero 5, 7 na 10. Ibiranga bisanzwe birimo ingufu za voltage zigera kuri 8–36 V, IP67 irwanya ivumbi n'amazi, ubushyuhe bunini bwo gukora kuva kuri -10 °C kugeza kuri 65 °C, na MIL-STD-810G irwanya gushyuha no guhindagura. Serivisi zo guhindura za OEM na ODM zirahari. Dushobora gushushanya ibikoresho byihariye bihuye n'imiterere ya bisi y'imodoka yawe, imiterere y'imikorere n'ibisabwa mu mushinga. Twandikire kugira ngo ubone amakuru arambuye.
