Hauv cov tshuab siv hauv kev tsim kho, cov khoom siv ua liaj ua teb niaj hnub, cov tsheb npav neeg caij thiab lwm yam, lub tsheb npav CAN ua haujlwm ua lub hauv paus tseem ceeb ntawm kev sib txuas lus hluav taws xob ntawm lub tsheb, uas yog lub luag haujlwm rau kev xa cov ntaub ntawv thiab kev sib cuam tshuam ntawm lub cav, lub thawv iav thiab cov sensors sab nraud. Raws li lub hauv paus tseem ceeb ntawm tib neeg-tshuab sib cuam tshuam thiab cov chaw khaws cov ntaub ntawv hauv lub cab, tus lej thiab kev ua tau zoo ntawm CAN channels ntawm cov ntsiav tshuaj rugged-mounted tsheb ncaj qha txiav txim siab qhov kev ua tiav ntawm kev sau cov ntaub ntawv tsheb thiab kev ruaj khov ntawm kev sib txuas lus. Tsab xov xwm no yuav piav qhia txog qhov sib txawv tseem ceeb ntawm ib qho CAN thiab ob lub CAN, nrog rau lawv cov chaw siv tseem ceeb, los pab cov neeg siv khoom zam kev ua yuam kev yuav khoom xws li software-simulated CAN thiab cov channel nthuav dav gateway uas tau tshaj tawm cuav tias yog cov khoom siv ntau-CAN hauv zos.
Cov Kev Sib Txuas Lus Kho Vaj Tse CAN Uas Muaj Kev Ywj Pheej vs. Gateway-Expanded / Software-Simulated CAN
Tus qauv ib leeg rau kev txiav txim siab txog lub peev xwm ntawm CAN ntawm lub ntsiav tshuaj rugged yog seb lub mainboard SoC puas koom nrog cov khoom siv tswj hwm CAN ib txwm muaj. Cov channels nthuav dav los ntawm software-simulated CAN lossis sab nraud USB / Ethernet CAN gateways tsis tuaj yeem phim cov khoom siv kho vajtse ib txwm muaj, thiab qhov sib txawv ntawm cov khoom siv kho vajtse tseem ceeb ntawm ob qho kev daws teeb meem tsis tuaj yeem them rov qab los ntawm kev hloov kho software.
Kev Teeb tsa Kho Vajtse Txheem ntawm Native TAU
Txhua txoj channel muaj cov khoom siv kho vajtse tshwj xeeb: ib qho CAN maub los tswj, ib qho CAN transceiver ceev ceev, ib qho resistor sib phim, ib qho hluav taws xob cais ntxiv rau lub voj voog digital cais, thiab ib qho TVS tiv thaiv hluav taws xob cais. Cov hluav taws xob, av thiab cov teeb liab ntawm txhua txoj channel raug cais tawm tag nrho. Cov hluav taws xob luv luv, kev tso tawm hluav taws xob lossis kev cuam tshuam hluav taws xob ntawm ib txoj channel yuav tsis kis mus rau lwm txoj channel, tshem tawm qhov kev pheej hmoo ntawm kev ua txhaum hla kev sib kis thoob plaws hauv network.
Cov Qhov Tsis Zoo ntawm Gateway-Expanded / Software-Simulated CAN
Cov Rooj Vag yog cov khoom siv xa mus rau cov txheej txheem. Txhua cov lus CAN sib koom tib cov peev txheej ua haujlwm CPU thiab ib qho chaw muaj zog yam tsis muaj kev cais cov khoom siv kho vajtse. Cov ntaub ntawv ntau ntxiv los ntawm ntau ntu tsheb npav ua rau CPU thauj khoom ntau ntxiv thiab ua rau muaj kev ncua sijhawm xa mus rau millisecond. Kev ua tsis tiav ntawm lub rooj vag tuaj yeem cuam tshuam txhua ntu tsheb npav txuas nrog tib lub sijhawm, thiab hauv cov xwm txheej hnyav ua rau muaj kev sib txuas lus ECU tag nrho ntawm lub tsheb. Cov kev daws teeb meem no tsis ua raws li cov kev cai nyab xeeb ntawm cov tsheb tsim kho, thiab tsuas yog tsim nyog rau kev debugging ib ntus xwb es tsis yog kev saib xyuas tas mus li 24/7.
Ib lub CAN (Qauv Nkag-Qib Sib Zog)
Nruab nrog tsuas yog ib pawg ntawm CAN maub los thiab ib-channel transceiver, txhawb kev sib txuas rau ib ntu tsheb npav xwb. Rau cov tsheb uas muaj ntau lub tsheb npav architectures, cov xov hlau yuav tsum tau unplugged manually thiab rov txuas dua kom tau txais cov ntaub ntawv hloov pauv, ua rau kev nyeem synchronous ntawm cov xwm txheej ua haujlwm los ntawm ob lub tshuab ywj pheej tsis yooj yim sua. Thaum muaj ntau lub nodes thiab cov lus hnyav nyob rau ntawm lub tsheb npav, tus nqi thauj khoom tsheb npav yooj yim tshaj qhov txwv 70% kev pheej hmoo, ua rau muaj kev sib tsoo ntawm cov lus, kev poob pob tsis tu ncua thiab kev sib txuas lus qeeb. Kev saib xyuas lub sijhawm tiag tiag ntawm lub tsheb thiab kev ua haujlwm kuaj mob tob UDS tsis tuaj yeem khiav tib lub sijhawm; ECU flashing thiab kev daws teeb meem yuav tsum tau txiav qhov txuas saib xyuas lub tsheb thiab cuam tshuam cov ntaub ntawv xa tawm ntawm cov tsheb thauj khoom.Ib lub CAN tsuas yog siv tau rau cov xwm txheej yooj yim uas muaj cov qauv tsheb npav ib lub tsheb, cov txheej txheem tswj hwm hluav taws xob yooj yim thiab tsis muaj qhov yuav tsum tau kuaj xyuas qhov tob.
Ob Lub Taub Hau (Tus Qauv Txheem Tseem Ceeb)
Lub mainboard muaj ob lub CAN hardware uas ywj pheej tag nrho, cais los ntawm hluav taws xob. Ob lub channel no tsis sib tw rau cov khoom siv kho vajtse, tuaj yeem teeb tsa ywj pheej nrog cov nqi baud sib txawv, thiab txhawb kev sib txuas lus ceev ceev txog li 1 Mbps. Kev sau cov ntaub ntawv synchronous dual-bus, kev saib xyuas thiab kev kuaj mob tau txais kev txhawb nqa, npog ntau dua 90% ntawm cov xwm txheej ua haujlwm ib txwm rau cov tsheb hnyav, ua rau nws yog qhov kev teeb tsa tseem ceeb rau kev tsim kho, kev thauj khoom thiab kev lag luam tshuab ua liaj ua teb.
1. Kev Sau Cov Ntaub Ntawv Synchronous Dual-Bus rau Kev Them Tag Nrho ntawm Cov Ntaub Ntawv Ua Haujlwm:
Channel 1 txuas rau J1939 lub tsheb npav fais fab (cav, kis, lub kaw lus nres), thaum Channel 2 txuas rau lub tsheb npav hydraulic lossis lub tsheb npav tswj lub cev. Cov neeg ua haujlwm tuaj yeem saib cov xwm txheej ua haujlwm ntawm lub ntsiav tshuaj, thiab lub platform backend sib sau ua ke cov ntaub ntawv ua haujlwm hauv lub sijhawm tiag tiag yam tsis muaj kev hloov pauv xov hlau lossis kev sib koom ua ke cov ntaub ntawv.
2. Kev Saib Xyuas thiab Kev Tshawb Fawb Sib Xws rauZoo duaKev Txij Nkawm:
Channel 1 tswj hwm 24/7 lub sijhawm tiag tiag upload ntawm lub tsheb xwm txheej, kev siv roj thiab cov tswb ceeb toom txhaum rau kev saib xyuas cov tsheb tas mus li. Channel 2 ua UDS kev kuaj mob txhaum tob thiab ECU program flashing yam tsis cuam tshuam kev saib xyuas, txhim kho kev saib xyuas cov tsheb kom zoo dua qub.
3. Kev Cais Tawm Ntawm Lub Tsheb Npav Thawj thiab Cov Khoom Siv Peripherals kom Tshem Tawm Kev Cuam Tshuam:
Cov channel tshwj xeeb cais lub tsheb lub tshuab tswj hluav taws xob tseem ceeb ntawm cov khoom siv sab nraud. Kev ua haujlwm tsis zoo lossis kev cuam tshuam los ntawm cov khoom siv sab nraud tseem nyob hauv ib txoj channel thiab tsis tuaj yeem cuam tshuam rau lub tsheb fais fab qub, lav qhov kev ua haujlwm ruaj khov thiab muaj kev nyab xeeb ntawm lub tsheb lub tshuab tswj hluav taws xob tag nrho.
