Ib.Puas yog PoE hloov qhov loj dua qhov zoo dua?
Txij li thaum muaj ntau lub zog siv hluav taws xob hauv cov cuab yeej saib xyuas tam sim no, cov tuam txhab hloov pauv nyiam tsim PoE keyboards nrog lub zog siab dua. Txawm li cas los xij, ntau yam khoom ntawm kev ua lag luam tsuas yog ua raws li cov khoom siv hluav taws xob tag nrho, thiab tsis txhob suav cov naj npawb ntawm cov chaw nres nkoj. Thaum lub zog nce, tag nrho cov nqi ntawm cov cuab yeej tseem yuav nce ntxiv, yog li tus nqi yuav khoom yuav nce ntxiv. Yog li ntawd, thaum cov neeg siv yuav, lawv yuav tsum xaiv qhov tsim nyog hloov raws li qhov xwm txheej tiag tiag, tsis yog lub zog siab dua, qhov zoo dua.
二.Dab tsi yog qhov txaus ntshai ntawm PoE thaum lub sij hawm muab hluav taws xob?
1. Lub zog tsis txaus
820.af tus qauv PoE tso zis hluav taws xob tsawg dua 15.4w, uas yog txaus rau IPC dav dav, tab sis rau siab zog PD, lub zog tso zis tsis tuaj yeem ua tau raws li qhov yuav tsum tau ua;
2. Muaj kev pheej hmoo siab heev
Feem ntau hais lus, PoE hloov pauv yuav muab lub zog rau ntau lub hauv ntej-kawg IPCs tib lub sijhawm. Yog hais tias lub hwj chim mov module ntawm qhov hloov pauv tsis ua haujlwm, nws yuav cuam tshuam rau kev ua haujlwm ntawm txhua lub koob yees duab, thiab qhov kev pheej hmoo siab heev;
3. Cov cuab yeej siv siab thiab cov nqi tu
Piv nrog rau lwm txoj hauv kev siv hluav taws xob, PoE lub tshuab hluav taws xob yuav ua rau cov khoom ua haujlwm tom qab muag muag. Los ntawm qhov kev xav ntawm kev nyab xeeb, kev ruaj ntseg ntawm ib lub hwj chim mov yog qhov zoo tshaj plaws.
三Dab tsi yog qhov kev nyab xeeb kis ntawm PoE fais fab mov?
Qhov kev nyab xeeb kis tau tus mob ntawm POE fais fab mov yog 100 meters, thiab nws raug pom zoo kom siv lub super tsib tag nrho tooj liab network cable. Cov kab hluav taws xob ncaj qha tuaj yeem kis tau deb heev nrog cov qauv Ethernet cables, yog li vim li cas qhov kev sib kis tau raug txwv rau 100 meters? Qhov tseeb yog tias qhov siab tshaj plaws kis tau tus mob ntawm PoE hloov feem ntau yog nyob ntawm cov ntaub ntawv kis tau tus mob. Thaum qhov kev ncua deb tshaj 100 meters, cov ntaub ntawv qeeb thiab pob ntawv poob yuav tshwm sim. Yog li ntawd, nyob rau hauv txoj kev tsim kho tiag tiag, qhov kev ncua deb yuav tsum zoo dua tsis pub tshaj 100 meters. Txawm li cas los xij, twb muaj qee qhov PoE hloov pauv uas tuaj yeem ncav cuag qhov sib kis ntawm 250 meters, uas yog txaus rau kev siv hluav taws xob ntev. Nws tseem ntseeg tau tias nrog kev txhim kho ntawm PoE fais fab mov thev naus laus zis nyob rau yav tom ntej, kev sib kis yuav txuas ntxiv mus.
四.Kuv puas yuav tsum tau yuav tus qauv PoE hloov? Puas tuaj yeem siv tsis tau tus qauv?
Xaiv tus qauv lossis tsis yog tus qauv, qhov no feem ntau yog nyob ntawm lub zog AP, IP
Lub koob yees duab txhawb nqa dab tsi? 48, 24, 12 v. Yog tias nws yog 48v, koj yuav tsum xaiv tus qauv PoE hloov; Yog hais tias nws yog 24 los yog 12v, koj yuav tsum nrhiav tau ib tug sib xws tsis-tus qauv hloov, ntawm chav kawm, tus txheej txheem kuj ua tau, tab sis yog hais tias koj yuav ib tug qauv, koj yuav tsum tau nruab nrog ib tug PD splitter.
Los ntawm cov lus piav qhia, peb tuaj yeem pom tias qee zaum cov keyboards tsis yog tus qauv kuj muaj, thiab tus nqi yuav qis dua, tab sis peb tseem ceeb toom koj kom yuav cov keyboards txheem. Vim tias qhov hloov tsis tau tus qauv tsis muaj PoE nti thiab tsis pom lub cuab yeej, nws yog ib qho yooj yim los tsim ib qho luv luv Circuit Court hlawv cov cuab yeej, uas tuaj yeem hlawv qhov chaw nres nkoj ntawm lub teeb, lossis ua rau hluav taws kub heev; thaum tus qauv hloov pauv yuav raug sim thaum nws tau siv los ua kom tsis txhob hlawv lub cuab yeej.
五.Yuav ua li cas xaiv lub PoE hloov rau kev saib xyuas kev ruaj ntseg thiab kev pab them nqi wireless?
Muaj ntau ntau hom PoE keyboards, xws li 100M mus rau 1000M, mus rau tag nrho gigabit, nrog rau qhov sib txawv ntawm hom tsis tswj thiab tswj, thiab qhov sib txawv ntawm cov chaw nres nkoj sib txawv. Yog tias koj xav xaiv qhov kev hloov tsim nyog, koj yuav tsum muaj kev xav zoo thiab ua tiav. . Ua ib qhov project uas yuav tsum tau saib xyuas qhov tseeb ua piv txwv.
1. Xaiv tus qauv PoE hloov
2. Xaiv 100M lossis 1000M hloov
Hauv qhov kev daws teeb meem tiag tiag, nws yog ib qho tsim nyog los sib xyaw cov koob yees duab, thiab xaiv qhov tsis xws li lub koob yees duab daws teeb meem, tus nqi me ntsis, thiab tus lej ncej. Kev soj ntsuam cov cuab yeej tsim khoom lag luam yuav muab cov cuab yeej ntsuas kev ua haujlwm bandwidth, thiab cov neeg siv tuaj yeem siv cov cuab yeej los xam cov bandwidth xav tau thiab xaiv qhov hloov PoE uas tsim nyog.
3. Xaiv af lossis ntawm tus qauv PoE hloov
Xaiv raws li cov khoom siv saib xyuas lub zog. Piv txwv li, yog tias lub koob yees duab ntawm lub npe nrov yog siv, lub zog yog 12W max. Hauv qhov no, kev hloov pauv ntawm tus qauv af yuav tsum tau xaiv. Lub zog ntawm lub koob yees duab dome siab yog 30W max. Hauv qhov no, nws yog ib qho tsim nyog yuav tsum siv qhov hloov ntawm tus qauv.
Plaub, xaiv tus naj npawb ntawm cov chaw nres nkoj ntawm qhov hloov
Raws li tus naj npawb ntawm cov chaw nres nkoj, PoE keyboards tuaj yeem muab faib ua 4 qhov chaw nres nkoj, 8 chaw nres nkoj, 16 chaw nres nkoj thiab 24 chaw nres nkoj, thiab lwm yam, uas tuaj yeem saib xyuas lub zog, qhov ntau, qhov chaw ntawm cov khoom siv, hloov hluav taws xob thiab xaiv tus nqi.
