Dab tsi yog cais thiab tsis cais lub zog hluav taws xob?
Oct 25, 2021
Thaum tsim hluav taws xob circuits rau embedded systems lossis xaiv cov khoom siv hluav taws xob ua tiav, ib qho teeb meem tseem ceeb uas yuav tsum tau xav txog yog seb puas yuav siv cov kev daws teeb meem sib cais lossis tsis cais tawm. Ua ntej sib tham, cia peb nkag siab lub ntsiab lus ntawm kev sib cais thiab tsis nyob ib leeg, thiab cov yam ntxwv tseem ceeb ntawm ob.
1, Lub tswv yim ntawm kev sib cais thiab tsis yog kev sib cais ntawm lub hwj chim mov.
Kev sib cais thiab tsis sib cais ntawm cov khoom siv hluav taws xob feem ntau yog rau kev hloov cov khoom siv hluav taws xob. Cov kev pom zoo hauv kev lag luam yog:
a) Cov khoom siv hluav taws xob cais tawm: tsis muaj hluav taws xob ncaj qha sib txuas ntawm cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob hauv hluav taws xob, thiab cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob yog insulated high-impedance xeev, tsis muaj lub voj voog tam sim no.
b) Cov khoom siv hluav taws xob tsis sib cais: muaj lub voj voog ncaj nraim ntawm cov tswv yim thiab cov zis, piv txwv li, cov tswv yim thiab cov khoom siv sib koom ua ke.
2, Qhov zoo thiab qhov tsis zoo ntawm cov khoom siv hluav taws xob sib cais thiab cov khoom siv hluav taws xob tsis sib cais.
Txhawm rau xaiv cov khoom siv hluav taws xob sib cais lossis tsis cais tawm, koj yuav tsum nkag siab tias qhov yuav tsum tau muaj rau lub hwj chim ntawm cov phiaj xwm tiag tiag, tab sis ua ntej ntawd, koj yuav tsum nkag siab qhov sib txawv tseem ceeb ntawm cov khoom siv hluav taws xob cais thiab tsis cais:
a) Kev cais module yog nrog kev ntseeg siab dua, tab sis tus nqi kuj yog siab thiab kev ua haujlwm tsis zoo.
b) Cov qauv tsis sib cais muaj cov qauv yooj yim, nrog tus nqi qis thiab kev ua haujlwm siab, tab sis kev ua haujlwm tsis zoo.
3, Cais tawm thiab tsis cais cov khoom siv fais fab piv txwv:
Los ntawm kev nkag siab txog qhov zoo thiab qhov tsis zoo ntawm cov khoom siv hluav taws xob sib cais thiab tsis sib cais, peb paub tias lawv muaj lawv tus kheej qhov zoo. Rau qee qhov kev xaiv embedded fais fab mov, peb tuaj yeem txiav txim kom raug.
a) Qhov twg yuav tsum tau muaj kev nyab xeeb, xws li AC-DC los ntawm cov khoom siv hluav taws xob lossis cov khoom siv kho mob, kom ntseeg tau tias kev nyab xeeb ntawm tus kheej, yuav tsum siv lub zog hluav taws xob cais, thiab qee zaum, yuav tsum siv lub zog hluav taws xob ntxiv.
b) Txhawm rau txhim kho kev tiv thaiv kev cuam tshuam kev ua haujlwm thiab ua kom muaj kev ntseeg siab ntawm lub zog ntawm lub hauv ntej ntawm lub cev, feem ntau siv cov khoom siv hluav taws xob cais tawm.
c) Rau cov chaw nres nkoj I / O sab nraud, txhawm rau kom ntseeg tau tias kev ua haujlwm txhim khu kev qha ntawm lub kaw lus, nws tseem pom zoo kom cais I / O cov chaw nres nkoj.
d) Lub IC los yog ib feem ntawm lub voj voog nyob rau hauv lub rooj tsav xwm Circuit Court yog lub zog, los ntawm qhov kev xav ntawm cov nqi kev ua tau zoo thiab ntim, cov kev daws teeb meem uas tsis yog cais tawm yog nyiam.
e) Rau cov khoom siv hluav taws xob ntawm kev sib txuas lus hauv kev lag luam mus ntev, txhawm rau txo qhov cuam tshuam hauv av muaj peev xwm sib txawv thiab kev cuam tshuam ntawm kev sib txuas, ib qho hluav taws xob sib cais feem ntau yog siv los siv hluav taws xob rau txhua qhov kev sib txuas lus sib cais.
f) Rau qee lub sijhawm uas siv roj teeb lub zog thiab muaj cov kev xav tau ruaj khov, yuav tsum tau siv cov khoom siv hluav taws xob tsis sib cais.
Rau LIGHT VICTOR coj cov khoom siv teeb pom kev zoo, ob qho tib si kev sib cais thiab tsis cais cov khoom siv hluav taws xob yog muaj. Rau kev ua tau zoo thiab tus nqi yog vim li cas, feem ntau ntawm cov teeb yog nrog cov khoom siv hluav taws xob tsis sib cais, tab sis hais txog kev nyab xeeb, cov khoom siv hluav taws xob ntawm cov teeb pom kev siab mast yog nrog cov khoom siv hluav taws xob cais. Thov txuas thiab qhia rau peb paub koj cov kev xav tau, peb tuaj yeem muab kev daws teeb meem rau koj!
