kauj ruam nce cable yog dab tsi?

Txhawb Nqaxov hlauyog ib hom xov hlau uas ua rau lub zog hluav taws xob tso zis ntau dua. Nws lub luag haujlwm tseem ceeb yog hloov cov qhov hluav taws xob qis USB chaw nres nkoj mus rau hauv 9V / 12V DC cov zis kom ua tau raws li qhov yuav tsum tau ua ntawm qee yam khoom siv uas xav tau 9V / 12V voltage fais fab mov. Lub luag haujlwm ntawm kab txhawb nqa yog los muab lub zog ruaj khov thiab txhim khu kev qha rau cov khoom siv hluav taws xob qis uas xav tau 9V. 12V voltage, ua rau lawv ua haujlwm li qub.

Muaj qhov sib txawv tseem ceeb hauv kev ua haujlwm ntawm kab boost thiab kab data. Cov xov hlau data feem ntau yog siv rau kev xa cov ntaub ntawv thiab cov ntaub ntawv, yam tsis muaj kev hloov pauv voltage. Nws feem ntau yog siv los xa cov ntaub ntawv, suab, video, thiab lwm yam ntaub ntawv ntawm cov khoom siv hluav taws xob. Cov xov hlau data raug cuam tshuam los ntawm kev cuam tshuam teeb liab thaum lub sijhawm xa, yog li qee txoj kev siv tshuab xav tau los xyuas kom meej tias kev xa cov ntaub ntawv muaj kev ntseeg siab. Thiab kab boost tsom mus rau kev hloov pauv voltage los muab cov khoom siv hluav taws xob siab xav tau, xws li routers thiab optical modem, uas tsis muaj feem cuam tshuam rau kev xa cov ntaub ntawv.

Lub luag haujlwm ntawmnce qib cable yog qhov dav heev thiab tseem ceeb. Ntau yam khoom siv, xws li feem ntau cov routers, cov miv kho qhov muag, FM xov tooj cua, lossis lwm yam khoom siv me me, xav tau qhov hluav taws xob ntawm 9V lossis 12V kom ua haujlwm tau zoo. Cov kab txhawb nqa muab qhov hluav taws xob xav tau los ntawm kev hloov pauv sab hauv ntawm PCB board, ua kom ntseeg tau tias kev ua haujlwm ruaj khov ntawm cov khoom siv no thiab tiv thaiv kev txwv kev ua haujlwm lossis kev ua tsis tiav los ntawm qhov hluav taws xob tsis txaus. Tsis tas li ntawd, hauv qee qhov kev siv, cov xov tooj txhawb nqa kuj tseem tuaj yeem txuas nrog lub taub hau them xov tooj ntawm tes kom them lwm yam khoom siv hluav taws xob tsawg, xws li Bluetooth hais lus, cov khoom ua si me me, thiab xov tooj cua.

Hauv luv luv, kev txhawb nqaxov hlauyog ib hom xov hlau siv rau kev hloov pauv hluav taws xob, uas nws lub luag haujlwm tseem ceeb yog hloov cov khoom siv hluav taws xob qis mus rau hauv cov zis hluav taws xob siab. Nws lub luag haujlwm yog los muab lub zog ruaj khov rau cov khoom siv uas xav tau lub zog tshwj xeeb (tsawg dua 20V) kom ntseeg tau tias cov khoom siv ua haujlwm ib txwm. Hauv kev sib piv, cov xov hlau ntaub ntawv yog cov xov hlau siv rau kev xa cov ntaub ntawv thiab cov ntaub ntawv, uas muaj qhov sib txawv tseem ceeb hauv kev ua haujlwm thiab daim ntawv thov piv rau cov xov hlau txhawb nqa. Hom kab txhawb nqa no tuaj yeem muab lub zog thaum muaj xwm txheej ceev rau koj lub router thaum lub sijhawm hluav taws xob tsis ua haujlwm.
