Ukadaulo wa PoE (Power over Ethernet) wakhala gawo lofunika kwambiri pa zida zamakono zama netiweki, ndipo mawonekedwe a PoE switch sangangotumiza deta, komanso zida zamagetsi kudzera mu chingwe chomwecho cha netiweki, zomwe zimapangitsa kuti mawaya azigwira ntchito mosavuta, kuchepetsa ndalama ndikuwonjezera magwiridwe antchito a netiweki. Nkhaniyi isanthula mokwanira mfundo yogwirira ntchito, zochitika zogwiritsira ntchito komanso zabwino za mawonekedwe a PoE switch poyerekeza ndi mawonekedwe achikhalidwe kuti akuthandizeni kumvetsetsa bwino kufunika kwa ukadaulo uwu pakuyika netiweki.
Momwe ma PoE switch interfaces amagwirira ntchito
TheKusintha kwa PoEChida ichi chimatumiza mphamvu ndi deta nthawi imodzi kudzera mu chingwe cha Ethernet, zomwe zimapangitsa kuti mawaya azigwira ntchito mosavuta komanso kuti zipangizo zizigwira ntchito bwino. Njira yake yogwirira ntchito imaphatikizapo njira zotsatirazi:
Kuzindikira ndi kugawa magulu
Choyamba, switch ya PoE imazindikira ngati chipangizo cholumikizidwa (PD) chikuthandizira ntchito ya PoE, ndipo imazindikira yokha mulingo wa mphamvu yake wofunikira (Kalasi 0~4) kuti igwirizane ndi magetsi oyenera.
Kupereka magetsi ndi kutumiza deta
Pambuyo potsimikizira kuti chipangizo cha PD chikugwirizana, chosinthira cha PoE chimatumiza deta ndi mphamvu nthawi imodzi kudzera m'magawo awiri kapena anayi a zingwe zopotoka, kuphatikiza magetsi ndi kulumikizana.
Kusamalira ndi kuteteza mphamvu mwanzeru
Maswichi a PoE ali ndi ntchito zogawa mphamvu, chitetezo cha overload komanso chitetezo cha short-circuit kuti zitsimikizire kuti zipangizo zikugwira ntchito bwino. Chipangizo choyendetsedwa ndi magetsi chikachotsedwa, magetsi a PoE amasiya okha kuti asamawononge mphamvu.
Zochitika za pulogalamu ya PoE switch interface
Ma interface a PoE switch amagwiritsidwa ntchito kwambiri m'magawo ambiri chifukwa cha kusavuta kwawo komanso kugwira ntchito bwino, makamaka pakuwunika chitetezo, ma netiweki 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 ndi kutumiza deta kwa makamera a IP. Ukadaulo wa PoE ungathandize kwambiri mawaya. Palibe chifukwa cholumikizira mawaya amagetsi pa kamera iliyonse padera. Chingwe chimodzi chokha cha netiweki chimafunika kuti magetsi ndi ma signal a kanema zitheke, zomwe zimapangitsa kuti ntchito yotumizira igwire bwino ntchito komanso kuchepetsa ndalama zomangira. Mwachitsanzo, pogwiritsa ntchito switch ya Gigabit PoE ya madoko 8, mutha kulumikiza makamera angapo mosavuta kuti muwonetsetse kuti ma netiweki akuluakulu achitetezo akugwira ntchito bwino.
Mphamvu Yopanda Waya ya AP
Poika ma netiweki a Wi-Fi m'mabizinesi kapena m'malo opezeka anthu ambiri, ma switch a PoE angapereke deta ndi mphamvu pazida za AP zopanda zingwe. Mphamvu ya PoE ingathandize kuti mawaya azigwira ntchito mosavuta, kupewa kuti ma AP opanda zingwe azilepheretsedwa ndi malo osungira magetsi chifukwa cha mavuto a magetsi, komanso kuthandizira mphamvu yamagetsi yakutali, zomwe zimathandiza kuti ma netiweki opanda zingwe azigwira ntchito bwino. Mwachitsanzo, m'masitolo akuluakulu, m'mabwalo a ndege, m'mahotela ndi m'malo ena, ma switch a PoE amatha kupeza mosavuta ma waya ambiri opanda zingwe.
Nyumba zanzeru ndi zipangizo za IoT
Mu nyumba zanzeru, maswichi a PoE amagwiritsidwa ntchito kwambiri mu makina owongolera mwayi wolowera, magetsi anzeru, ndi zida zoyezera, zomwe zimathandiza kukwaniritsa makina odziyimira pawokha komanso kukonza mphamvu moyenera. Mwachitsanzo, makina owunikira anzeru amagwiritsa ntchito magetsi a PoE, omwe amatha kupangitsa kuti maswichi akutali aziwongolera komanso kusintha kuwala, ndipo ndi othandiza kwambiri komanso amasunga mphamvu.
Mawonekedwe a PoE switch ndi mawonekedwe achikhalidwe
Poyerekeza ndi ma interfaces achikhalidwe, ma interfaces a PoE switch ali ndi ubwino waukulu pakulumikiza ma waya, kugwiritsa ntchito bwino, komanso kuyang'anira:
Zimapangitsa kuti mawaya ndi kuyika zikhale zosavuta
Mawonekedwe a PoE amaphatikiza deta ndi magetsi, kuchotsa kufunikira kwa zingwe zowonjezera zamagetsi, zomwe zimachepetsa kwambiri zovuta za mawaya. Mawonekedwe achikhalidwe amafuna mawaya osiyana pazida, zomwe sizimangowonjezera ndalama zomangira, komanso zimakhudza kukongola ndi kugwiritsa ntchito malo.
Kuchepetsa ndalama ndi mavuto okonza
Ntchito yamagetsi yakutali ya ma switch a PoE imachepetsa kudalira ma socket ndi zingwe zamagetsi, kuchepetsa ndalama zolumikizira mawaya ndi kukonza. Ma interface achikhalidwe amafunikira zida zowonjezera zamagetsi ndi kasamalidwe, zomwe zimawonjezera zovuta zosamalira.
Kusinthasintha kowonjezereka komanso kufalikira
Zipangizo za PoE sizimaletsedwa ndi malo omwe magetsi ali ndipo zimatha kuyikidwa mosavuta m'malo omwe ali kutali ndi magetsi, monga makoma ndi denga. Mukakulitsa netiweki, palibe chifukwa choganizira za mawaya amagetsi, zomwe zimawonjezera kusinthasintha ndi kukula kwa netiweki.
Chidule
Kusintha kwa PoEMa interface akhala chida chofunikira kwambiri pakuyika ma netiweki amakono chifukwa cha ubwino wake wophatikiza deta ndi magetsi, kupangitsa kuti mawaya azigwira ntchito mosavuta, kuchepetsa ndalama komanso kukulitsa kusinthasintha. Yawonetsa kufunika kogwiritsa ntchito bwino pakuwunika chitetezo, ma netiweki opanda zingwe, nyumba zanzeru, intaneti ya zinthu zamafakitale ndi madera ena. M'tsogolomu, ndi chitukuko chachangu cha intaneti ya zinthu, makompyuta a m'mphepete ndi ukadaulo wanzeru zopanga, ma switch a PoE apitilizabe kugwira ntchito yofunika kwambiri pothandiza zida za netiweki kuti zikwaniritse kuyika bwino, kosinthasintha komanso mwanzeru.
