Ethernet VS bhazi rechinyakare

1） 1TPCE = Imwe (1) Yakamonyoroka Peya 100 Megabit (C = zana = zana) Ethernet 1 Yakamonyoroka pair tambo 100MEthernet

2) RTPGE=Yakaderedzwa Twisted Pair Gigabit Ethernet

3) GEPOF = Gigabit Ethernet Pamusoro pePlastiki Optical Fiber

4) 100BASE-T1 = 100 Megabit Baseband Imwe Peya 100M Ethernet (1 yakamonyoroka peya)

5) 1000BASE-T1 = 1 Gigabit Baseband One Pair 1000M Ethernet (1 twisted pair)

6) 1000BASE-RH = Gigabit Ethernet Pamusoro pePlastiki Optical Fiber

7) Vhura/VHURA Mubatanidzwa = One Pair Ethernet Network Alliance

8） OABR = (OPEN Alliance) BroadR-Reach

Iro zita rekutanga re100BASE-T1, apo IEEE yakanga isingabatanidzwe uye Open Alliance yakaunza Broadcom's BroadR-Reach tekinoroji kuchikamu chemotokari.

9) TSN - Time Sensitive Network

10) AVB - Audio / Vhidhiyo yekubhura tekinoroji

Chii chinonzi 100BASE-T1

100BASE-T1 isanganiswa yakavakirwa pane iripo Ethernet tekinoroji.

1) IEEE 100BASE-TX

- Duplex simplex kutaurirana

- MLT-3 (yakawanda-nhanho kutapurirana) -> 125Msps (miriyoni samples/sekondi) 65~80MHz bandwidth)

- Maviri maviri akamonyoroka - hapana kukanganisa kugadzirisa coding

- Hapana echo uye crosstalk kudzima tekinoroji muDSP

Sarudzo Yemhinduro Equilibrium (DFE)

2) IEEE 1000BASE-T - yakazara duplex kutaurirana

- 4D-PAM5 -> 125Msps (mamiriyoni esampuli pasekondi) 65~80MHz bandwidth) - mana akamonyoroka peya

- Partial mhinduro yekufambisa sefa

-Kuwedzera mazinga ekukanganisa kugadzirisa coding

- DSP ine echo uye crosstalk kudzima tekinoroji

Sarudzo Yemhinduro Equilibrium (DFE)

3) IEEE 100BASE-T1 - yakazara duplex kutaurirana - PAM3 - 66.7Msps (miriyoni samples pasekondi) 27MHz bandwidth - imwe chete yakamonyoroka peya

—— Echo kukanzura tekinoroji —— Decision Feedback Equilibrium (DFE)

3. Ethernet VS zvechinyakare bhazi

3.1 Switch-based network kutaurirana

1) Manodhi ese ari mubhazi rechinyakare akabatana kune imwechete nzira yekufambisa; semuenzaniso, materminal node (ECUs) anogona kusungirirwa kune rimwe bhazi reCAN, uye masaini emagetsi pabhazi reCAN anogona kukanganisa ese materminal akasungirirwa bhazi.

Kazhinji, tinodaidza CAN seCAN Bhazi kana CAN Network.

2) Ethernet inzira yakashandurwa yetiweki yekukurukurirana, uko materminal node ese anofanirwa kubatanidzwa kuburikidza nekuchinja uye ruzivo rwese rwunofambiswa runofanira kuendeswa mberi nekuchinja.Mu switched network network, imwe network tambo inogona chete kubatanidza madoko maviri pasina branching.Naizvozvo, isu kazhinji usataure nezve Ethernet bhazi, asi pane Ethernet network.

4. Kushandiswa kwe-on-board Ethernet

4.1 Aerial mufananidzo maonero - yakakwirira-kumhanya yekubatanidza

1) Broadcom BroadR-Reach, 100 Mbit / s, yakazara duplex, yakamonyoroka peya - inotsiva inodhura yakadzivirirwa waya harnesses.

- Kukurukurirana kwenzira mbiri

2) Shandisa yakakwirira bandwidth

3) MAC-yakavakirwa vhidhiyo kutenderera ine yakasimba nguva zvinodiwa

4) Enhanced ADAS mabasa (akawedzera makamera, millimeter-wave radar, laser radar, nezvimwewo) - yakakwirira resolution uye furemu chiyero, kushomeka kudiki.

- Inoda mwero wekutapurirana we1000Mbit/s uye pamusoro

4.2 Ethernet semushure metiweki yemukati wemotokari

Bhasi remotokari remangwana richatsiva bhazi reCAN neEthernet semusana wetiweki, uye ma subnets achave akaumbwa nevatongi vakati wandei. FlexRay communication bus.Different domain controllers yakabatana kuburikidza nepamusoro-performance Ethernet semusana wetiweki, uye kuchinjana kwemashoko kunowanikwa kuburikidza neEthernet magedhi, nokudaro pamwe chete kuumba E / E architecture inobva kune domain controllers.

4.3 Pa-bhodhi Ethernet yekufambisa simba

Simba pamusoro peEthernet (POE) itekinoroji inokwanisa kufambisa data pamusoro petambo dzakamonyoroka panguva imwe chete ichigonesa midziyo yekupedzisira yakabatana, ichibvisa kudiwa kwetambo dzemagetsi dzekunze dzematerminals uye kuderedza kuoma kwemagetsi.

Iwo makuru emagetsi ekupa maitiro ePOE akajairwa magetsi emagetsi system ndeaya:

1) Mhepo iri pakati pe44-57V, ine kukosha kwe48V.

2) Iyo yakanyanya kubvumidzwa ikozvino ndeye 550mA, uye yakanyanya kutanga ikozvino 500mA.

3) Yakajairika kushanda ikozvino 10-350mA, uye iyo yakawandisa yekuona ikozvino ndeye 350-500mA.

4) Pasi pemamiriro asina-mutoro, iyo yakanyanya kudiwa ikozvino 5mA.

5) Ipa mazinga mashanu emagetsi ekukumbira kwePD (Simba mudziyo) zvishandiso kubva pa3.84 kusvika 12.95W, ine huwandu hwe13W.

4.4 Wireless function ye-on-board Ethernet Wireless function ndiyo imwe mukana wepa-bhodhi Ethernet.WiFi zvakare ine musiyano wekushandiswa kwemotokari - WAVE (Wireless Access in Vehicle Environments).Kuunzwa kwe-on-board Ethernet pasina mubvunzo kuchava chinhu chakanakisa chekusimudzira kuunzwa kwewireless communication technology WAVE mundima yemotokari, inopa hwaro hwemuviri. yekushandiswa kwemaodhiyo nevhidhiyo uye yakakwirira-tsanangudzo mepu mukutaurirana-chaiyo-nguva, uye zvakare inopa yakawanda yekufungidzira nzvimbo yekushandiswa kweV2X tekinoroji.
