Kev piav qhia rau SN65HVD251
HVD251 yog tsim los siv rau hauv daim ntawv thov siv Controller Area Network (CAN) serial kev sib txuas lus lub cev txheej raws li ISO 11898 Standard.HVD251 muab qhov sib txawv ntawm kev xa mus rau lub tsheb npav thiab qhov sib txawv tau txais kev muaj peev xwm mus rau CAN maub los ntawm qhov nrawm mus txog 1 megabits ib ob (Mbps).
Tsim los rau kev ua haujlwm nyob rau hauv ib puag ncig hnyav, cov cuab yeej nta cross-wire, overvoltage thiab poob ntawm av tiv thaiv mus rau ± 36 V. Kuj featured yog overtemperature tiv thaiv raws li zoo raws li -7-V rau 12-V ntau hom-hom, thiab kam rau ua rau transients. ntawm ± 200 V. Lub transceiver interfaces ib leeg-kawg CAN maub los nrog qhov sib txawv CAN tsheb npav pom nyob rau hauv kev lag luam, tsev automation, thiab kev siv tsheb.
Rs, tus pin 8, xaiv ib qho ntawm peb hom kev ua haujlwm sib txawv: kev kub ceev, kev tswj txoj kab nqes, lossis hom qis zog.Cov kev ua haujlwm siab ceev yog xaiv los ntawm kev sib txuas tus pin 8 rau hauv av, tso cai rau lub transmitter tso zis transistors hloov sai li sai tau yam tsis muaj kev txwv ntawm qhov nce thiab nqis nqes.Qhov nce thiab poob nqes hav tuaj yeem hloov kho los ntawm kev sib txuas ib qho resistor rau hauv av ntawm tus pin 8;txoj kab nqes yog proportional rau tus pin cov zis tam sim no.Kev tswj kev nqes hav nrog tus nqi hluav taws xob sab nraud ntawm 10 kΩ muab txog 15-V / µs slew tus nqi;100 kΩ muab txog 2-V / µs slew tus nqi.
Yog tias qib siab logic raug siv rau Rs pin 8, lub cuab yeej nkag mus rau qhov qis-tam sim no standby hom uas tus neeg tsav tsheb raug kaw thiab lub receiver tseem ua haujlwm.Tus tswj hwm raws tu qauv hauv zos xa rov qab lub cuab yeej mus rau hom qub thaum nws xa mus rau lub npav.
1. Leej twg yog cov neeg ua haujlwm hauv koj lub tuam tsev R & D?Koj qhov kev tsim nyog yog dab tsi?
-R & D Tus Thawj Coj: tsim lub tuam txhab cov phiaj xwm mus ntev R & D thiab tuav cov kev taw qhia ntawm kev tshawb fawb thiab kev loj hlob;Qhia thiab saib xyuas r&d department los siv lub tuam txhab r&d lub tswv yim thiab txhua xyoo R&D txoj kev npaj;Tswj kev txhim kho cov khoom lag luam thiab kho cov phiaj xwm;Teem cov khoom zoo tshaj plaws tshawb fawb thiab txhim kho pab pawg, tshawb xyuas thiab kev cob qhia txog cov neeg ua haujlwm.
R & D Tus Thawj Coj: ua cov khoom tshiab R & D txoj kev npaj thiab ua kom pom qhov ua tau ntawm txoj kev npaj;Saib xyuas thiab tswj qhov kev nce qib thiab ua haujlwm zoo ntawm r&d;Tshawb nrhiav kev tsim khoom tshiab thiab nthuav tawm cov kev daws teeb meem zoo raws li cov neeg siv khoom xav tau hauv ntau qhov chaw
R&d cov neeg ua haujlwm: sau thiab txheeb xyuas cov ntaub ntawv tseem ceeb;Computer programming;Ua cov kev sim, ntsuas thiab ntsuas;Npaj cov ntaub ntawv thiab khoom siv rau kev sim, kev sim thiab tshuaj xyuas;Sau cov ntaub ntawv ntsuas, ua cov lej thiab npaj cov kab kos;Ua cov ntawv tshawb fawb
2. Koj cov khoom tshawb fawb thiab kev tsim kho lub tswv yim yog dab tsi?
-Txoj kev xav thiab xaiv cov khoom lag luam lub tswv yim thiab kev ntsuam xyuas cov khoom txhais thiab cov phiaj xwm tsim thiab kev tsim cov khoom kuaj thiab kev siv tau tso rau kev lag luam
