Uaea Ethernet ta'avale

I aso nei, o loʻo faʻaauau pea le atinaʻeina o pisinisi taʻavale i lalo o le taʻitaʻiga o tekinolosi faʻaonaponei eseese.Faatasi ai ma le tele o le alualu i luma i faiga fesoasoani avetaʻavale (ADAS), faiga faʻamatalaga, ma tekinolosi faʻatautaia tutoʻatasi, o le manaʻoga mo le bandwidth i taavale faʻaonaponei ua faʻateleina foi.O mea e mafai ona suia pea ma fa'atekonolosi fa'atupuina e fa'atupuina ai le tele o mana'oga o fa'amaumauga, ma e taua tele le fa'agaioia o fa'amaumauga i ni auala fou.I aso ua tuanaʻi, o manaʻoga faʻaoga o taʻavale masani na faʻatapulaʻaina i faiga faʻatonutonu taʻavale poʻo faiga faʻatonutonu tino, e manaʻomia ai naʻo le faʻaogaina o faʻamatalaga o le faitau afe o bits i le sekone (kbps).I aso nei, o taʻavale atamai ua faʻapipiʻiina i se numera tele o masini, faʻaogaina faʻamatalaga maualuga, ma faiga faʻatautaia e faʻavae i luga o le atamai faʻapitoa (AI) ma le aʻoaʻoina o masini (ML), ma le tele o LIDAR, RADAR, ma mea puʻeata e gaosia ai terabytes o faʻamaumauga. , e mafua ai le faʻateleina o le faʻalavelave.O le mea lea, e taua tele le faʻaogaina o le Ethernet taʻavale mo le televave, faʻatuatuaina, ma le ultra-low-latency fesoʻotaʻiga.

Mana'oga fa'apitoa mo uaea Ethernet ta'avale (e leai ni feso'ota'iga).

O faʻamatalaga o le OPEN Alliance (TC2 100Mbps, TC9 1000Mbps) faʻamalamalama manino le manaʻoga mo laina eletise Ethernet e aunoa ma ni fesoʻotaʻiga.O le OPEN Alliance ua faʻamalamalamaina manaʻoga autu mo laina manaʻomia - o faʻataʻitaʻiga faʻatinoga talafeagai (tau faʻatatau i fua faʻatatau eseese):

Impedance Z -> igoa 100Ohm mo tulaga faapalepale eseese

Fa'aofiina gau IL—se pi'o lamolemole > tulaga eseese fua faatatau-e fa'alagolago i taimi

Fa'afo'i gau RL —> fua fa'atatau e fa'atatau ile taimi

Fa'apaleni fa'atinoga LCL1 ma le LCTL2—> fua faatatau ma mamanu uaea e fa'alagolago i mana'oga o alaleo eseese

Fa'ato'a fa'atasi—> e fa'atatau i na'o uaea fa'apipi'i

Talipupuni Lelei—> e na'o uaea puipui

Atina'e ulu uaea Ethernet ta'avale, LEONI Saina

O LEONI o loʻo avea nei ma taʻitaʻi i le pisinisi uaea taʻavale, o le tele o tulaga o loʻo i ai nei uaea e faʻavae i luga o ana faʻamatalaga faʻamaonia faʻamaonia, ua leva ona auai i le OPEN, IEEE3 ma le SAE4 ma isi faʻalapotopotoga faʻapitoa, ma galulue faʻatasi ma sui auai e atiina ae 100Mbit / s ma 1Gbit/s uaea Ethernet taavale.LEONI Dacar o LEONI's automotive data cable brand, lea e masani ona aofia ai coaxial ma tele-core data cables, LEONI automotive Ethernet cable ona o ona uiga faʻamatalaga o loʻo aofia ai foi i le Dacar series, LEONI Dacar series e aofia ai faʻamatalaga eseese i totonu o le taavale, i o loʻo iai nei LEONI Dacar 100 Gigabit ma Gigabit Ethernet oloa ua faʻapipiʻiina ma faʻaogaina lelei i le tele o faʻataʻitaʻiga o le lalolagi Siamani, Amerika, faʻatau tutoʻatasi ma isi OEM.E le muta ai iina LEONI, ua naunau Lene e alu i tua atu o lena tulaga.LeONI's Dacar Ethernet uaea fa'amatala uiga fa'asalalau e pei ole fa'aliliuga fa'aletonu mana'omia mo uaea e le'i puipuia.O le mamanu uaea fa'apipi'i e fa'amautinoaina o lo'o fa'apipi'iina le fa'alava ma ni a'afiaga leaga i lalo o tulaga e pei o le matua, le mama ma le susu.Mo faʻapipiʻi faʻapipiʻi EMC, ua ofoina atu e LEONI le faʻaogaina o uaea LEONI Dacar Ethernet puipui.O nei uaea ua uma ona gaosia tele ma faʻaaogaina i totonufaiga meapueata panoramic.

maketi Ethernet maketi i le lumana'i

Talu ai ona o le Ethernet na vave faia, o le tuʻuina atu o faʻamatalaga taimi moni e leʻi mafaufauina.Faatasi ai ma le tele o faʻafiafiaga leo ma vitio o loʻo ulufale atu i totonu o le vaalele, o le numera o ECUs ma le manaʻoga mo le faʻaogaina o malosiaga o ECUs ua faʻaalia ai le faʻatupulaia o le pa, lea e sili atu ona manino i le ADAS ma le lumanaʻi o le leai o se taʻavale, ma le manaʻoga mo le faʻaogaina o bandwidth. ua amata foi ona pa.O lenei mea ua mafua ai le siʻitia tele o le tau o masini eletise eletise, i le tasi itu, o le siʻitia o le numera ma le lelei o faiga ECU, ona o le tufatufaina atu o komepiuta, o se numera tele o punaoa faakomepiuta ua faʻaumatia, ma o loʻo matou talanoa e uiga i taavale. Ethernet fa'aaoga se tasi pa'aga o uaea unshielded ma connectors laiti ma sili atu fa'apipi'i, fa'aaoga le unshielded milo paga e mafai ona lagolagoina le 15m felauaiga mamao (mo shielded milo palua e mafai ona lagolagoina 40m), o lenei optimization faagasologa e mafai ona ausia e le taavale Ethernet manaomia taavale EMC.Faʻaitiitia tau fesoʻotaʻiga i totonu o taʻavale e oʻo atu i le 80% ma le mamafa o le uaea i totonu o le taʻavale e oʻo atu i le 30%, o le PHY o le 100M Automotive Ethernet faʻaaogaina le 1G Ethernet tekinolosi e mafai ai ona fesoʻotaʻi lua-auala i luga o se paga e tasi e ala i le faʻaogaina o le faʻaleaogaina.PoE masani ua mamanuina mo Ethernet ma 4 paipa o uaea, o lea na fausia faapitoa ai le PoDL mo Ethernet taʻavale e tuʻuina atu ai le 12VDC poʻo le 5VDC voltage tuʻuina atu mo le faʻaogaina masani o le ECU o le iunite faʻaeletoroni i luga o le tasi pea o uaea.O le mea moni, o le manaʻomia mo le bandwidth o se mea foi lea, ma o masini eseese, aemaise lava lidar ma mea pueata maualuga, e tatau ona tuʻuina atu faʻamatalaga e faʻaaoga ai le Ethernet.
