Ukadaulo wa PoE (Mphamvu pa Efaneti) wakhala gawo lofunikira pazida zamakono zamakono, ndipo mawonekedwe osinthira a PoE sangangotumiza zidziwitso zokha, komanso zida zamagetsi zamagetsi kudzera pa chingwe chofananira cha netiweki, kufewetsa waya, kuchepetsa ndalama komanso kuwongolera magwiridwe antchito apaintaneti. Nkhaniyi isanthula mwatsatanetsatane mfundo yogwirira ntchito, momwe mungagwiritsire ntchito komanso ubwino wa mawonekedwe osinthira a PoE poyerekeza ndi mawonekedwe achikhalidwe kuti akuthandizeni kumvetsetsa kufunikira kwaukadaulowu pakutumiza maukonde.
Momwe ma PoE switch interfaces amagwirira ntchito
TheKusintha kwa PoEmawonekedwe amatumiza mphamvu ndi deta nthawi imodzi kudzera pa chingwe cha Efaneti, chomwe chimapangitsa mawaya kukhala osavuta komanso kumapangitsa kuti zida ziziyenda bwino. Njira yake yogwirira ntchito imakhala ndi izi:
Kuzindikira ndi kugawa
Kusintha kwa PoE koyamba kumazindikira ngati chipangizo cholumikizidwa (PD) chimathandizira ntchito ya PoE, ndikudziwikiratu mphamvu yake yofunikira (Kalasi 0 ~ 4) kuti igwirizane ndi magetsi oyenera.
Kupereka mphamvu ndi kutumiza deta
Pambuyo potsimikizira kuti chipangizo cha PD n'chogwirizana, kusintha kwa PoE kumatumiza deta ndi mphamvu panthawi imodzi kupyolera mumagulu awiri kapena anayi a zingwe zopotoka, kuphatikizapo magetsi ndi kulankhulana.
Kuwongolera mphamvu ndi chitetezo chanzeru
Ma switch a PoE ali ndi kugawa mphamvu, chitetezo chochulukirachulukira komanso ntchito zoteteza pafupipafupi kuti zitsimikizire kuti zida zikuyenda bwino. Chida choyendetsedwa ndi magetsi chikalumikizidwa, magetsi a PoE amangoyima kuti asawononge mphamvu.
PoE switch interface application mawonekedwe
PoE switch interfaces amagwiritsidwa ntchito kwambiri m'magawo ambiri chifukwa cha kuphweka kwawo komanso kuchita bwino, makamaka pakuwunika chitetezo, ma network opanda zingwe, nyumba zanzeru komanso zochitika zamakampani pa intaneti ya Zinthu.
Njira yowunikira chitetezo
Pankhani yowunikira makanema, ma switch a PoE amagwiritsidwa ntchito kwambiri popereka magetsi komanso kutumiza kwamakamera a IP. Ukadaulo wa PoE utha kuphweka mawaya. Palibe chifukwa choyimbira zingwe zamagetsi pa kamera iliyonse padera. Chingwe chimodzi chokha cha netiweki chimafunika kuti mutsirize magetsi ndi kufalitsa ma siginecha a kanema, zomwe zimakulitsa bwino ntchito komanso kuchepetsa ndalama zomanga. Mwachitsanzo, pogwiritsa ntchito 8-port Gigabit PoE switch, mutha kulumikiza mosavuta makamera angapo kuti muwonetsetse kugwira ntchito kokhazikika kwa maukonde akuluakulu otetezedwa.
Wireless AP Power Supply
Mukatumiza ma netiweki a Wi-Fi m'mabizinesi kapena m'malo opezeka anthu ambiri, ma switch a PoE amatha kupereka data ndi mphamvu pazida zopanda zingwe za AP. Magetsi a PoE amatha kuphweka mawaya, kupewa ma AP opanda zingwe kuchepetsedwa ndi malo okhala ndi socket chifukwa chazovuta zamagetsi, ndikuthandizira magetsi azitali, kukulitsa bwino kufalikira kwa ma network opanda zingwe. Mwachitsanzo, m'malo akuluakulu ogulitsa, ma eyapoti, mahotela ndi malo ena, masinthidwe a PoE amatha kupeza mosavuta kufalikira kwa zingwe zazikulu.
Nyumba zanzeru ndi zida za IoT
M'nyumba zanzeru, ma switch a PoE amagwiritsidwa ntchito kwambiri pamakina owongolera mwayi wofikira, kuyatsa kwanzeru, ndi zida zamasensa, zomwe zimathandizira kukwaniritsa makina omangira komanso kukhathamiritsa mphamvu zamagetsi. Mwachitsanzo, makina owunikira anzeru amagwiritsa ntchito magetsi a PoE, omwe amatha kukwaniritsa kuwongolera kwakutali komanso kusintha kowala, ndipo ndi yabwino kwambiri komanso yopulumutsa mphamvu.
PoE kusintha mawonekedwe ndi chikhalidwe chikhalidwe
Poyerekeza ndi mawonekedwe achikhalidwe, mawonekedwe osinthira a PoE ali ndi maubwino akulu pakubweza, kugwiritsa ntchito bwino, komanso kasamalidwe:
Imathandizira mawaya ndi kukhazikitsa
Mawonekedwe a PoE amaphatikiza deta ndi magetsi, kuthetsa kufunikira kwa zingwe zowonjezera mphamvu, kuchepetsa kwambiri zovuta za waya. Kulumikizana kwachikhalidwe kumafuna waya wosiyana pazida, zomwe sizimangowonjezera ndalama zomanga, komanso zimakhudza kukongola komanso kugwiritsa ntchito malo.
Chepetsani ndalama ndi zovuta kukonza
Ntchito yamagetsi yakutali yama switch a PoE imachepetsa kudalira sockets ndi zingwe zamagetsi, kuchepetsa ma wiring ndi kukonza ndalama. Zolumikizira zachikhalidwe zimafunikira zida zowonjezera zamagetsi ndi kasamalidwe, ndikuwonjezera zovuta zokonza.
Kusinthasintha kosinthika ndi scalability
Zipangizo za PoE sizimaletsedwa ndi malo amagetsi ndipo zimatha kutumizidwa kumadera akutali ndi magetsi, monga makoma ndi kudenga. Mukakulitsa maukonde, palibe chifukwa choganizira mawaya amagetsi, omwe amawonjezera kusinthasintha komanso kusinthasintha kwa maukonde.
Chidule
Kusintha kwa PoEmawonekedwe asanduka chida chofunikira kwambiri pakugwiritsa ntchito maukonde amakono chifukwa cha zabwino zake zophatikizira deta ndi magetsi, kufewetsa mawaya, kuchepetsa ndalama komanso kukulitsa kusinthasintha. Yawonetsa kufunika kogwiritsa ntchito pakuwunika chitetezo, ma network opanda zingwe, nyumba zanzeru, intaneti yazinthu zamafakitale ndi magawo ena. M'tsogolomu, ndikukula kwachangu kwa intaneti ya Zinthu, makompyuta am'mphepete komanso ukadaulo wanzeru zopanga, ma switch a PoE apitiliza kuchita gawo lofunikira pothandizira zida zama netiweki kuti zikwaniritse bwino, zosinthika komanso zanzeru.
