Hnub no, kuv xav piav qhia qhov sib txawv ntawm ECU systems ntawm SDLG thiab Volvo.
Ntau tus neeg tau xav tias SDLG thiab Volvo cov tshuab zoo ib yam. Nws yog qhov tseeb tias ob lub tuam txhab muaj kev sib koom tes zoo thiab ua tiav rau lub sijhawm ua ntej 2021, thiab lawv cov khoom tau dov tawm ntawm tib txoj kab ntau lawm. Qhov no ua rau muaj kev xav tsis zoo tias ob lub tshuab muaj ntau dua lossis tsawg dua qhov qub. Txawm li cas los xij, tsis yog li ntawd.
Nyob ib ncig ntawm 2021, SDLG pib ua haujlwm ywj pheej R & D thiab pib tsim nws tus kheej cov khoom txhawb nqa. Qhov no suav nrog lub ntsiab ECU ntawm nws cov kev tswj hluav taws xob, uas yog tus kheej tsim thiab tsim los ntawm SDLG thiab paub hauv kev lag luam raws li lub Beigu Electronic Control System.
Cia peb saib luv luv ntawm lub rooj tsav xwm tseem ceeb ntawm Beigu system. Nws khaws ib co nta ntawm Volvo system. Piv txwv li, nws cov interface zoo ib yam rau Volvo's, tab sis cov ntsiab lus tseem ceeb tau hloov kho. Tsis tas li ntawd, nws tau tshem tawm txoj haujlwm ntawm ib qho 1587 kev sib txuas lus kab uas pom nyob rau hauv Volvo system, tuav tsuas yog lub tsheb npav CAN.
Qhov no yog vim li cas ntau tus neeg siv khoom thiab cov neeg ua haujlwm excavator tau tshaj tawm tias lawv tsis tuaj yeem saib cov ntaub ntawv hluav taws xob hluav taws xob lossis cov ntaub ntawv ceeb toom lub cav ntawm qhov chaw - nws yog qhov tshwm sim ncaj qha ntawm SDLG tshem tawm 1587 qhov teeb meem txhaum cai. Qhov no kuj tau ua rau ntau tus kws kho mob tsis meej pem thiab tawm tsam los daws qhov tsis raug, uas yog qhov tsis zoo ntawm qhov kev hloov kho no.
Yog li ntawd, ib qho kev ceeb toom rau kev kho cov haujlwm: ib txwm ua ntej txheeb xyuas tus qauv SDLG thiab hom kev siv nws siv. Cov qauv tsim ua ntej 2021 zoo li yuav nruab nrog Volvo system. Rau cov qauv tsim tom qab 2021, lossis txawm tias qee qhov tsim tawm tom qab 2018 lossis 2019, ib feem yuav tau siv Beigu system. Koj tuaj yeem paub qhov txawv ntawm lawv los ntawm kev saib cov txheej sab nrauv - muaj qhov sib txawv tseem ceeb ntawm Volvo thiab Beigu ECUs. Cov tshuab sib txawv xav tau cov kev daws teeb meem sib txawv.
Cia peb ua piv txwv: piv txwv li a 400 Plus model muaj qhov teeb meem uas qhov proportional valve tsis muaj cov zis. Txoj kev sim rau qhov no txawv ntawm Kawasaki proportional li qub. Nrog rau Beigu system, koj tuaj yeem tshem tawm qhov sib npaug ntawm lub valve thiab sim nws ncaj qha. Raws li ib txwm muaj rau cov qauv no, koj yuav tsum ntsuas 24V voltage ntawm lub interface. Thaum lub proportional valve txuas, qhov voltage yuav poob mus rau hauv 10V. Yog tias muaj qhov ua txhaum, qhov ntsuas hluav taws xob ntsuas ntawm lub interface yuav tsis yog 24V - nws yuav nyob ib ncig ntawm kaum volts. Qhov no yog qhov koj yuav pom nyob rau hauv qhov kev sim qhib-circuit.
Tseem muaj lwm yam kev txhaum. Piv txwv li, yog lub teev meter nyeem ntawm a 600 qauv mam li nco dheev rov pib dua rau 0, lossis dhia mus rau ib puas txhiab lossis ntau pua txhiab teev, qhov teeb meem feem ntau yog nrog rau chav tswj.
Lwm yam teeb meem xws li tsis muaj peev xwm rov ua kom lub cav lossis tsis ua haujlwm ib txwm tuaj yeem tshwm sim los ntawm ECU malfunctions. Hauv cov xwm txheej zoo li no, ECU yuav tsum tau muab tshem tawm mus kuaj.
Cov no yog qee qhov kev ua txhaum uas cuam tshuam nrog Beigu system. Kuv vam tias cov ntaub ntawv no yuav pab tau rau cov phooj ywg hauv kev lag luam.
