Ethernet VS bus gakondo

1） 1TPCE = Imwe (1) Yahinduwe Yombi 100 Megabit (C = ikinyejana = 100) Ethernet 1 Umugozi wa kabili 100MEthernet

2) RTPGE = Yagabanijwe Yagabanijwe Yombi Gigabit Ethernet

3) GEPOF = Gigabit Ethernet hejuru ya fibre optique

4) 100BASE-T1 = 100 Megabit Baseband Igice kimwe 100M Ethernet (1 igoretse)

5) 1000BASE-T1 = 1 Gigabit Baseband Igice kimwe 1000M Ethernet (1 igoretse)

6) 1000BASE-RH = Ethernet ya Gigabit hejuru ya fibre optique

7) Gufungura / Gufungura Ihuriro = Ihuriro rimwe rya Ethernet Network

8） OABR = (Gufungura Ihuriro) BroadR-Kugera

Izina ryambere rya 100BASE-T1, mugihe IEEE itabigizemo uruhare kandi Open Alliance yazanye ikoranabuhanga rya Broadcom's BroadR-Reach mumashanyarazi.

9) TSN - Umuyoboro wigihe

10) AVB - Ikoranabuhanga rya Audio / Video

Niki 100BASE-T1

100BASE-T1 ni ihuriro rishingiye ku buhanga bwa Ethernet.

1） IEEE 100BASE-TX

- Itumanaho rya Duplex

- MLT-3 (kwanduza urwego rwinshi) -> 125Msps (miriyoni ntangarugero / isegonda) 65 ~ 80MHz umurongo mugari)

- Babiri bagoretse - nta kode ikosora

- Nta echo na tekinoroji yo guhagarika ikoranabuhanga muri DSP

Ibitekerezo byo Kuringaniza Ibingana (DFE)

2) IEEE 1000BASE-T - itumanaho ryuzuye

- 4D-PAM5 -> 125Msps (miriyoni y'icyitegererezo ku isegonda) 65 ~ 80MHz umurongo mugari) - bine bigoretse

- Igice cyo gusubiza igice cyoherejwe

- Inzego zinyongera zo gukosora amakosa

- DSP ifite tekinoroji na tekinoroji yo guhagarika

Ibitekerezo byo Kuringaniza Ibingana (DFE)

3) IEEE 100BASE-T1 - itumanaho ryuzuye rya duplex - PAM3 - 66.7Msps (miriyoni y'icyitegererezo ku isegonda) 27MHz umurongo mugari - umwe umwe

—— Ikoreshwa rya echo risubirwamo —— Icyemezo cyo Gusubiza Ibingana (DFE)

3. Ethernet VS bisi gakondo

3.1 Guhindura imiyoboro y'itumanaho

1) Imyanya yose kuri bisi gakondo ihujwe nuburyo bumwe bwo kohereza; urugero, imitwe myinshi ya terefone (ECUs) irashobora kwomekwa kuri bisi imwe ya CAN, kandi ibimenyetso byamashanyarazi kuri bisi ya CAN birashobora kugira ingaruka kuri terefone zose zometse kuri bisi.

Muri rusange, twita CAN nka CAN Bus cyangwa CAN Network.

2. ntukereke kuri bisi ya Ethernet, ahubwo ni umuyoboro wa Ethernet.

4. Gushyira mu bikorwa Ethernet

4.1 Ishusho yo mu kirere kureba - guhuza byihuse

1) Broadcom BroadR-Kugera, 100 Mbit / s, duplex yuzuye, ihindagurika - isimbuza ibyuma bihenze bikingiwe.

- Itumanaho ryuburyo bubiri

2) Koresha umurongo mwinshi

3) Amashusho ashingiye kuri MAC yerekana igihe gikenewe

4) Kunoza imikorere ya ADAS (kamera yinyongera, milimetero-yumuraba wa radar, laser radar, nibindi) - gukemura cyane nigipimo cyikadiri, kwikuramo bike

- Saba igipimo cyo kohereza 1000Mbit / s no hejuru

4.2 Ethernet nkumuyoboro winyuma wimodoka imbere

Bus izaza ibinyabiziga izasimbuza bisi ya CAN hamwe na Ethernet nkumuyoboro wumugongo, na subnets izaba igizwe nabagenzuzi benshi ba domaine.Buri domeni ikora itangwa numugenzuzi wa domaine, kandi guhuza sisitemu muri buri domeni birashobora gukoresha CAN na Bisi y'itumanaho ya FlexRay. Abagenzuzi batandukanye ba domaine bahujwe binyuze murwego rwohejuru rwa Ethernet nkumuyoboro wumugongo, kandi guhanahana amakuru bigerwaho binyuze mumarembo ya Ethernet, bityo tugahuriza hamwe ubwubatsi bwa E / E bushingiye kubagenzuzi ba domaine.

4.3 Muri bombo Ethernet yo kohereza amashanyarazi

Imbaraga hejuru ya Ethernet (POE) ni tekinoroji ishobora kohereza amakuru hejuru yinsinga zigoretse mugihe kimwe icyarimwe ikoresha ibikoresho byanyuma bihujwe, bikuraho gukenera insinga z'amashanyarazi zo hanze kugirango bigabanye kandi bigabanye ikibazo cyo gutanga amashanyarazi.

Ibintu nyamukuru bitanga amashanyarazi biranga POE sisitemu yo gutanga amashanyarazi ni:

1) Umuvuduko uri hagati ya 44-57V, hamwe nagaciro gasanzwe ka 48V.

2) Ikigereranyo ntarengwa cyemewe ni 550mA, naho intangiriro ntarengwa ni 500mA.

3) Imikorere isanzwe ikora ni 10-350mA, naho imiyoboro irenze urugero ni 350-500mA.

4) Mugihe kitarimo umutwaro, icyifuzo gisabwa ni 5mA.

5) Tanga ibyiciro bitanu byingufu zisabwa kubikoresho bya PD (Power power) ibikoresho kuva kuri 3.84 kugeza 12.95W, hamwe na 13W ntarengwa.

4.4 Imikorere idafite insinga ya Ethernet Imikorere ya Wireless niyindi nyungu yo kuri Ethernet.WiFi ifite kandi uburyo bwo gukoresha ibinyabiziga - WAVE (Wireless Access in Vehicle Environnement) kugirango ishyirwa mubikorwa ryamajwi na videwo hamwe namakarita asobanutse cyane mugutumanaho kwigihe, kandi inatanga umwanya wibitekerezo byo gukoresha tekinoroji ya V2X.
