2. Vim li cas thiaj yuav tsum tau siv tus qauv PoE hloov rau lub hwj chim?
Ua ntej tshaj plaws, nws yog ib qho tsim nyog los qhia meej qhov txawv ntawm tus qauv PoE keyboards thiab tsis yog tus qauv PoE keyboards. Tus qauv PoE fais fab mov hloov pauv muaj PoE tswj nti sab hauv, uas muaj kev ua haujlwm ntawm kev tshawb pom ua ntej lub hwj chim. Thaum lub cuab yeej txuas nrog, PoE injector yuav xa cov teeb liab mus rau lub network kom paub seb lub davhlau ya nyob twg hauv lub network yog PD ntaus ntawv uas txhawb nqa PoE fais fab mov.
Cov khoom tsis yog tus qauv PoE yog cov khoom siv hluav taws xob muaj zog network cable fais fab mov. Nws muab hluav taws xob sai li sai tau thaum nws yog powered. Tsis muaj kauj ruam tshawb nrhiav. Txawm hais tias lub davhlau ya nyob twg yog PoE powered ntaus ntawv los yog tsis, nws yuav muab lub hwj chim, thiab nws yog heev yooj yim mus hlawv cov khoom siv.
Siv Wangyue Technology MS series txheem PoE keyboards ua piv txwv. Tom qab lub hwj chim-on, lub hloov yuav cia li ntes lub powered ntaus ntawv. Yog tias nws pom tias lub tshuab hluav taws xob tsis yog PoE txuas nrog, nws yuav cia li nres lub zog hluav taws xob los tiv thaiv cov khoom siv hluav taws xob thiab tsis txhob hlawv. Qhov xwm txheej ntawm cov khoom siv tau tshwm sim, ua rau cov txheej txheem ntawm cov khoom siv hluav taws xob muaj kev nyab xeeb dua. Cov txheej txheem tshawb nrhiav yog raws li hauv qab no. Yog li ntawd, tus qauv PoE hloov yuav tsum tau siv rau lub hwj chim mov.
3. Yuav ua li cas kom paub qhov txawv ntawm tus qauv PoE thiab tsis yog tus qauv PoE yog qhov yooj yim heev, tsuas yog siv lub tshuab ntsuas ntau los ntsuas. Cov txheej txheem raws li hauv qab no:
Pib lub cuab yeej, kho lub multimeter mus rau qhov ntsuas qhov ntsuas hluav taws xob, thiab siv ob lub ntsuas ntsuas ntawm lub tshuab ntsuas ntsuas los kov lub hwj huam mov pins ntawm PSE ntaus ntawv (feem ntau 1/2, 3/6 lossis 4/5, 7/8 ntawm RJ45 chaw nres nkoj). ), yog tias ib lub cuab yeej muaj qhov tso zis ruaj khov ntawm 48V lossis lwm qhov ntsuas qhov ntsuas hluav taws xob (12V, 24V, thiab lwm yam) raug ntsuas, nws yog cov khoom siv tsis zoo. Vim hais tias nyob rau hauv cov txheej txheem no, PSE tsis ntes cov khoom siv hluav taws xob (ntawm no, multimeter), thiab ncaj qha siv 48V lossis lwm yam khoom siv hluav taws xob los muab lub zog.
Hloov pauv, yog tias tsis tuaj yeem ntsuas qhov voltage thiab rab koob ntawm multimeter dhia ntawm 2 thiab 10V, nws yog tus qauv POE. Vim tias nyob rau theem no, PSE tab tom sim PD sab (ntawm no yog multimeter), thiab lub multimeter tsis yog PD raws cai, PSE yuav tsis muab lub zog, thiab tsis muaj qhov ruaj khov voltage yuav raug tsim.
4. Puas yog PoE fais fab mov ruaj khov?
Hauv kev tsim kho thiab kev siv tiag tiag, tseem yuav muaj qhov xwm txheej uas PoE hloov tsis tuaj yeem muab lub zog lossis lub zog tsis ruaj khov. Puas yog PoE fais fab mov ruaj khov?
Qhov tseeb, PoE thev naus laus zis tau tsim los rau ntau xyoo, thiab tam sim no nyob rau hauv ib qho kev paub tab heev. Tus qauv PoE fais fab mov yog ruaj khov thiab muaj kev nyab xeeb txaus. Feem ntau ntawm cov xwm txheej yog vim qhov kev xaiv tsis yog tus qauv PoE hloov lossis cov xaim tsis zoo dhau lawm, lossis cov kev daws teeb meem tsim nws tus kheej tsis tsim nyog, lub zog hluav taws xob nyob deb tsis tau teeb tsa zoo, lossis ntau lub zog hluav taws xob txuas nrog, thiab cov khoom siv hluav taws xob tsis txaus (tshwj xeeb tshaj yog thaum lub ntsuas ntsuas ntsuas cua sov hom thaum hmo ntuj). Sijhawm). Yog li ntawd, hauv kev xa tawm tiag tiag, yog tias cov khoom siv hluav taws xob pom tias tsis ruaj khov, nws yuav tsum tau tshawb xyuas cov laj thawj sab nraud ua ntej.
5. Puas yog lub zog siab dua ntawm PoE fais fab mov hloov, qhov zoo dua?
Vim qhov tshwm sim ntawm cov khoom siv hluav taws xob siab xws li lub koob yees duab siab lub koob yees duab thiab cov xov tooj video hauv lub sijhawm tiag tiag, cov tuam txhab khoom siv network tau sib tw los tsim PoE keyboards nrog ntau zog tag nrho. Txawm li cas los xij, ntau yam khoom tsuas yog ua raws li kev txhim kho tag nrho lub zog, tsis quav ntsej txog kev sib raug zoo ntawm lub zog thiab tus naj npawb ntawm cov chaw nres nkoj. Thaum lub hwj chim siab, nws yuav inevitably nce tus nqi tag nrho ntawm cov cuab yeej. Raws li qhov tshwm sim, qhov hloov pauv PoE xaiv los ntawm tus neeg siv tsis yog qhov ua tau zoo thiab siv tau zoo.
Yog li ntawd, hauv kev xa tawm tiag tiag, txiav txim siab lub zog thiab ntau npaum li cas ntawm PD cov khoom siv raws li cov kauj ruam hauv nqe lus nug 1, thiab xaiv qhov tsim nyog tshaj plaws PoE hloov.
6. PoE fais fab mov nrug tsuas yog 100 meters?
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 kev hloov pauv PoE uas tuaj yeem ncav cuag kev sib kis ntawm 250 meters. Piv txwv li, Wangyue MS series tus qauv PoE hloov pauv siv L-PoE muaj nuj nqi, uas tuaj yeem txuas ntxiv PoE kis tau tus mob mus txog 250 meters kom tau raws li lub zog nyob deb. Nws tseem ntseeg tau tias nrog kev txhim kho ntawm PoE fais fab mov thev naus laus zis nyob rau yav tom ntej, qhov kev sib kis yuav txuas ntxiv mus ntxiv.
Qhov thib ob yog lub network cable. Lub network cable kuj txiav txim siab lub hwj huam mov nrug. Lub network cable nrog lub teb chaws tus qauv tshaj Qeb 5 thiab 6 yog ua tau, tshwj xeeb tshaj yog lub teb chaws tus qauv network cable tshaj Qeb 6 yog twv yuav raug hu ua tau. Qee cov neeg siv khoom siv qee qhov pheej yig thiab tsis zoo network cables, uas tsis tuaj yeem ua tau raws li qhov kev ncua deb ntawm lub hwj huam mov, thiab rov hais dua tias muaj teeb meem nrog peb Fengrunda PoE hloov lossis PoE splitter, tab sis thaum peb xa cov engineers dhau los, tsuas yog nrhiav tau. tawm Peb tsis muaj teeb meem nrog peb cov PoE keyboards thiab qhov teeb meem tau daws tom qab hloov lub network cable.
Muaj ntau tus neeg uas tsis tuaj yeem paub qhov txawv ntawm lub network cable yog lub network cable tsis tu ncua lossis tsis. Muaj ntau ntau fake network cables nyob rau hauv kev ua lag luam. Kuv yuav muab ob peb txoj hauv kev los txiav txim siab qhov tseeb ntawm lub network cable, rau kev siv nkaus xwb:
a. Rau ib txwm lub teb chaws tus qauv network cable, tus nqi kuj nyob ntawm qhov deb ntawm 10 meters mus rau 100 meters yog tsawg dua 10 ohms. Qhov no tuaj yeem ntsuas ncaj qha nrog lub multimeter. Thaum nws yog ntau tshaj 10 ohms, xws li tus nqi kuj nce mus txog 30 ohms, ces lub network cable yuav tsum yog fake;
b. Lub teb chaws tus qauv network cable, ib lub thawv ntawm txog 305 meters, tus nqi lag luam yog kwv yees li 450-500 yuan (tus nqi tuaj txawv teb chaws yuav siab dua), cov phooj ywg paub kuj tuaj yeem yuav nws rau 430 yuan, tab sis yog tias nws qis dua tus nqi no. , nws yog qhov tseeb fake.
c. Cov kab hluav taws xob hauv teb chaws tsis tu ncua yog txhua tus tooj liab ntshiab, lossis cov tooj liab tsis muaj oxygen, thiab lwm yam ntaub ntawv xws li tooj liab-clad hlau, tooj liab-clad txhuas, thiab lwm yam yog cuav.
