Ntau tus phooj ywg uas ua haujlwm hauv kev saib xyuas kev ruaj ntseg thiab kev them nyiaj wireless engineering muaj kev nkag siab zoo ntawm POE fais fab mov thiab paub txog cov txiaj ntsig ntawm PoE fais fab mov. Txawm li cas los xij, hauv kev xaim hluav taws xob tiag tiag, lawv pom tias kev xa tawm PoE muaj ntau qhov kev txwv, xws li siv cov txheej txheem xaim ib txwm siv thaum lub tshuab hluav taws xob sab saud thiab cov khoom siv qis kawg tsis txhawb POE.
Raws li paub zoo, cov txheej txheem xaim ib txwm muaj cov kab hluav taws xob siab thiab cov nqi zog, uas tsis tsim nyog rau kev saib xyuas tom ntej. Kab lus no tshawb txog plaub txoj hauv kev siv engineering ntawm PoE fais fab mov. Tom qab paub koj tus kheej nrog plaub txoj hauv kev no, koj tuaj yeem siv qhov yooj yim ntawm PoE fais fab mov kom txo tau kev txhawj xeeb hauv txhua qhov xwm txheej.
1, Ob lub keyboards thiab terminals txhawb PoE
Txoj kev no yog qhov yooj yim tshaj plaws rau POE keyboards kom txuas ncaj qha mus rau wireless APs thiab lub koob yees duab network uas txhawb nqa POE fais fab mov los ntawm cov cables network. Txawm li cas los xij, ob lub ntsiab lus hauv qab no kuj yuav tsum tau sau tseg:
1. Txiav txim siab seb lub POE hloov thiab wireless AP lossis lub koob yees duab network yog cov khoom siv POE txheem
2. Nws yog ib qho tsim nyog yuav tsum ua tib zoo paub meej cov lus qhia tshwj xeeb ntawm cov khoom siv network cable. Qhov zoo ntawm lub network cable yog qhov tseem ceeb. Cov kab hluav taws xob tsis zoo tuaj yeem ua rau AP lossis IPC tsis tuaj yeem txais lub zog lossis rov pib dua tas li
2, Hloov txhawb POE, lub davhlau ya nyob twg tsis txhawb POE
Cov tswv yim no txuas POE hloov mus rau POE cais, uas cais cov khoom siv hluav taws xob rau hauv cov ntaub ntawv teeb liab thiab lub zog. Muaj ob txoj kab tso zis, ib qho yog cov kab hluav taws xob tso tawm, thiab lwm qhov yog lub network cov ntaub ntawv teeb liab tso tawm kab, uas yog cov kab hluav taws xob tsis tu ncua. Cov zis hluav taws xob suav nrog 5V / 9 / 12V thiab lwm yam tsis yog POE terminals uas tuaj yeem phim ntau yam DC inputs, txhawb nqa tus qauv IEEE802.3af / 802.3at. Cov ntaub ntawv teeb liab tso zis cable, tseem hu ua ib txwm network cable, tuaj yeem txuas ncaj qha mus rau lub network chaw nres nkoj ntawm qhov tsis yog POE txais lub davhlau ya nyob twg.
3, Hloov tsis txhawb POE, lub davhlau ya nyob twg txhawb POE
Cov tswv yim no suav nrog kev sib txuas ntawm qhov hloov mus rau POE fais fab mov, uas ntxiv lub zog rau lub network cable thiab xa mus rau lub davhlau ya nyob twg. Qhov kev daws teeb meem no yog qhov tsim nyog rau kev nthuav dav cov kab hluav taws xob uas twb muaj lawm yam tsis muaj kev cuam tshuam rau thawj lub network.
4, Qhov hloov pauv tsis txhawb POE, thiab lub davhlau ya nyob twg tsis txhawb POE ib yam
Cov tswv yim no suav nrog kev sib txuas ntawm qhov hloov mus rau PoE fais fab mov, tom qab ntawd mus rau POE cais, thiab thaum kawg xa mus rau lub davhlau ya nyob twg.
Scheme 3 thiab Scheme 4 yog qhov tsim nyog rau kev hloov pauv ntawm cov kev sib txuas ib txwm siv, qhov twg qhov hloov pauv qub tsis txhawb POE fais fab mov tab sis xav ua kom zoo dua cov txiaj ntsig ntawm POE fais fab mov.
Hauv cov ntsiab lus, POE tuaj yeem siv rau hauv txhua qhov xwm txheej, ua kom yooj yim rau kev siv ntau yam yooj yim coj los ntawm POE. Nws kuj tseem ceeb heev uas yuav tau xaiv qhov hloov pauv PoE. Kev hloov POE zoo tuaj yeem ua rau tag nrho cov kab ke ruaj khov thiab tswj tau yooj yim. CF FIBERLINK's POE hloov thiab POE cais tau lav zoo, nrog zoo heev.
