Muaj nuj nqi
Hauv CAN (Controller Area Network) system, DB9 yog hom txuas, thiab qhov kev txiav tawm yog siv rau lub davhlau ya nyob twg. Lub tsheb npav CAN feem ntau yog ib qho kev sib tw, thiab lub davhlau ya nyob twg resistor yog siv ntawm ob qhov kawg ntawm CAN network thiab muaj ob lub luag haujlwm tseem ceeb hauv qab no:
Qhov sib txawv ntawm impedance:Lub davhlau ya nyob twg resistor pab kom phim lub impedance ntawm lub tsheb npav los xyuas kom meej tias lub teeb liab kis tau los ntawm lub tsheb npav Tsis muaj kev cuam tshuam tshwm sim thaum lub sijhawm sib kis. Qhov kev tiv thaiv ntawm qhov kev txiav tawm qhov hluav taws xob feem ntau yog 120 ohms, uas phim cov yam ntxwv impedance ntawm CAN tsheb npav.
Tshem tawm cov teeb liab ntug:Termination resistors pab txo cov teeb liab ntug ntawm lub npav thiab tiv thaiv cov teeb liab cuam tshuam los ntawm kev ua rau lub teeb liab distortion. Nyob rau hauv CAN system, lub davhlau ya nyob twg resistor tuaj yeem txo qhov amplitude thiab ntug kev hloov pauv ntawm lub teeb liab thiab xyuas kom ruaj khov ntawm cov teeb liab. Hauv CAN network, feem ntau yuav tsum tau txiav tawm cov resistor ntawm tsuas yog ob lub nodes. Ntawm ob qhov kawg ntawm lub network, muaj qhov resistor ntawm ib sab thiab tsis nyob rau sab nraud. Qhov no ua kom cov impedance txuam ntawm lub npav thiab pab tswj cov teeb liab zoo. Yog tias txiav tawm cov resistors raug muab rau ntawm txhua qhov ntawm lub network, cov teeb liab cuam tshuam thiab lwm yam teeb meem kev sib txuas lus yuav tshwm sim. Yog li ntawd, qhov tseeb configuration ntawm lub davhlau ya nyob twg resistor yog ib qho tseem ceeb heev los xyuas kom meej lub stability thiab kev cia siab ntawm lub CAN tsheb npav system.
