—— Tignoolajiyada burinta Echo —— Isku dheelitirnaanta Jawaab celinta Go'aanka (DFE)

3. Ethernet VS baska dhaqameed

3.1 Isgaadhsiinta shabakada ku salaysan beddelka

1) Dhammaan qanjidhada baska dhaqameedku waxay ku xidhan yihiin isla marinka gudbinta; tusaale ahaan, noodhka terminal badan (ECUs) ayaa lagu dhejin karaa hal bas oo CAN ah, iyo calaamadaha korantada ee baska CAN waxay saameyn karaan dhammaan marinnada ku xiran baska.

Guud ahaan, waxaan ugu yeernaa CAN sida CAN Bas ama Shabakadda CAN.

2)Ethernet waa hab isgaadhsiineed oo isku xidhan,halkaas oo dhamaan noodhadhka terminalku ay tahay in lagu xidho furayaasha iyo dhamaan macluumaadka la gudbiyo waa in lagu gudbiyaa shisheeyaha. ha tixraacin baska Ethernet, laakiin aad u tixraac shabakada Ethernet.

4. Codsiga Ethernet-board-ka

4.1 Muuqaalka muuqaalka hawada - isku xirka xawaaraha sare

1) Broadcom BroadR-Reach, 100 Mbit / s, laba-duplex buuxa, lammaane maroojin ah - waxay beddelaan xargaha siliga gaashaman ee qaaliga ah

- Isgaadhsiinta laba-geesoodka ah

2) Ka faa'iidayso xawaaraha sare

3) Ku-saleysan fiidiyooga MAC-ku-saleysan oo leh shuruudo waqti adag

4) Hawlaha ADAS ee la xoojiyay (kamerooyin dheeri ah, radar millimeter, radar laser, iwm.) - xallinta sare iyo heerka jir, cadaadis yar

- Waxay u baahan tahay xadiga gudbinta 1000Mbit/s iyo wixii ka sareeya

4.2 Ethernet oo ah shabakada laf dhabarta ee gudaha baabuurka

Baska baabuurta mustaqbalka wuxuu bedeli doonaa baska CAN ee Ethernet sida shabakada laf dhabarta, iyo subnet-yadu waxay ka koobnaan doonaan dhowr maamulayaal domain ah. Goob kasta oo shaqeynaya waxaa la siiyaa maamulaha domain, iyo isku xirka nidaamyada ku dhex jira domain kasta ayaa wali isticmaali kara CAN iyo Basaska isgaadhsiinta ee FlexRay

4.3 On-board Ethernet ee gudbinta korontada

Power over Ethernet (POE) waa tignoolajiyada gudbin karta xogta fiilooyinka laba-laaban iyadoo isla mar ahaantaana awood u siinaysa aaladaha dhamaadka ku xidhan, taas oo meesha ka saaraysa baahida loo qabo xadhkaha korantada dibadda ee terminalka isla markaana yaraynaysa kakanaanta sahayda korontada.

Tilmaamaha ugu muhiimsan ee tamarta korontada ee nidaamka POE caadiga ah waa:

1) Danabku wuxuu u dhexeeyaa 44-57V, oo leh qiime caadi ah 48V.

2) Hadda ugu badnaan la oggol yahay waa 550mA, ugu badnaan bilawga hadda waa 500mA.

3) Waqtigan xaadirka ah ee hawlgalka caadiga ah waa 10-350mA, ogaanshaha culeyska hadda waa 350-500mA.

4) Marka la eego xaaladaha wax-load ah, baahida ugu badan ee hadda jirta waa 5mA.

5) Bixi shan heer oo codsi koronto ah aaladaha PD (Aaladaha Korontada) oo u dhexeeya 3.84 ilaa 12.95W, ugu badnaan 13W.

4.4 Shaqada Wireless-ka ee dusha sare ee shaqada Ethernet Wireless-ka waa faa'iido kale oo ku jirta Ethernet-board.WiFi sidoo kale waxay leedahay kala duwanaansho loogu talagalay isticmaalka baabuurta - WAVE (Wireless Access in Vehicle Environments) . Soo bandhigida guddiga Ethernet waxay shaki la'aan noqon doontaa kicinta ugu fiican ee kor u qaadida hordhaca ah ee tiknoolajiyada isgaarsiinta wireless WAVE ee garoonka baabuurta, taas oo bixisa aasaas jireed. loogu talagalay hirgelinta maqal iyo muuqaal iyo khariidado qeexid sare ah ee isgaarsiinta waqtiga-dhabta ah, iyo sidoo kale waxay siisaa meelo badan oo male-awaal ah oo loogu talagalay isticmaalka farsamada V2X.
