PHY nyeredzi iri kusimuka mu-mu-motokari maapplication (akadai seT-BOX) yekumhanya-mhanya kwechiratidzo chekufambisa, nepo CAN ichiri nhengo yakakosha pakutepfenyura kwepasi-kumhanya kwemasaini.Iyo T-BOX yeramangwana ichanyanya kuda kuratidza mota ID, kushandiswa kwemafuta, mileage, trajectory, mamiriro emotokari (gonhi nemahwindo marambi, oiri, mvura nemagetsi, idle kumhanya, nezvimwewo), kumhanya, nzvimbo, hunhu hwemotokari. , kugadziridzwa kwemotokari, nezvimwewo pane network yemotokari uye nharembozha yemotokari, uye idzi dzinenge dzakaderera-kumhanyisa data kutapurirana kuri kuvimba nemunhu mukuru wechinyorwa chino, CAN.

Bhazi reCAN rakaunzwa neBosch kuGermany kuma1980 uye rave chikamu chakakosha uye chakakosha chemota.Kuti isangane nezvinodiwa zvakasiyana-siyana zvemukati-mumotokari masisitimu, bhazi reCAN rakakamurwa kuva-high-speed CAN uye yakaderera-inomhanya CAN.high-speed CAN inonyanya kushandiswa pakutonga kwemasimba emagetsi anoda kushanda kwepamusoro-nguva chaiyo, zvakadai sejini, automatic transmissions, uye zvikwata zvezviridzwa.Low-speed CAN inonyanya kushandiswa pakutonga kwekunyaradza masisitimu uye masisitimu emuviri anoda zvishoma-chaiyo-nguva kuita, senge air conditioning control, kugadzirisa chigaro, kusimudza hwindo, zvichingodaro.Muchikamu chino, tichatarisa pamusoro pekumhanya kweCAN.

Kunyangwe CAN iri tekinoroji yakakura kwazvo, ichiri kutarisana nematambudziko mukushandisa mota.Mubepa rino, tichatarisa mamwe ematambudziko ari kutarisana neCAN uye tosuma matekinoroji akakodzera ekuagadzirisa.Chekupedzisira, zvakanakira zveTI's CAN zvikumbiro uye zvigadzirwa zvayo "zvakaoma" zvinotsanangurwa zvakadzama.

Dambudziko rekutanga: EMI performance optimization

Sezvo kuwanda kwemagetsi mumotokari kunowedzera gore rega rega, iyo electromagnetic kuenderana (EMC) ye-mumotokari network iri kudiwa zvakanyanya, nekuti kana zvese zvikamu zvakabatanidzwa muhurongwa humwe, zvakakosha kuti ive nechokwadi chekuti subsystems inoshanda sezvaitarisirwa. , kunyangwe pakatarisana nemhoteredzo dzine ruzha.Rimwe rematambudziko makuru akatarisana neCAN kuwanda kwehutsi hunoitiswa neruzha rwemhando.

Nenzira yakanaka, CAN inoshandisa mutsauko wekubatanidza kutapurirana kudzivirira kunze ruzha kubatana.Mukuita, zvisinei, CAN transceivers haina kunaka uye kunyange zvishoma zvishoma asymmetry pakati peCANH neCANL inogona kuburitsa chiratidzo chinopindirana chekusiyanisa, izvo zvinoita kuti iyo common mode chikamu cheCAN (kureva chiyero cheCANH neCANL) chirege kuramba chiripo. DC chikamu uye uve data-rinoenderana ruzha.Kune marudzi maviri ekusaenzana kunoguma neruzha urwu: ruzha rwepasi-frequency rwunokonzerwa nekusawirirana pakati peiyo steady state common mode level mune inotonga uye inodzoreredza nyika, iyo ine hupamhi hwakawanda hwemhando yeruzha mapatani uye inoratidzika seyakatevedzana yakafanana. yakaparadzana discrete spectral mitsetse;uye ruzha rwepamusoro-ruzha runokonzerwa nekusiyana kwenguva pakati pekuchinja pakati peCANH neCANL, iyo inosanganisira pfupi pfupi uye kukanganisa kunokonzerwa nekusvetuka kwe data.Mufananidzo 1 pazasi unoratidza muenzaniso weyakajairika CAN transceiver inobuda yakajairika modhi ruzha.Dema (channel 1) iCANH, yepepuru (channel 2) iCANL uye girini inoratidza huwandu hweCANH neCANL, kukosha kwayo kwakaenzana nekaviri yevoltage yemodhi pane imwe nguva yakapihwa.
