PoE (Power over Ethernet), yomwe imadziwikanso kuti "Power over Ethernet", ndiukadaulo womwe ungapereke mphamvu pazida zama netiweki kudzera pazingwe zama netiweki. Ukadaulo wa PoE umatha kutumiza ma siginecha amagetsi ndi ma data nthawi imodzi, ndikuchotsa kufunikira kwa zingwe zowonjezera zamagetsi pazida. Mfundo yaukadaulo wa PoE ndikuwonjezera magetsi a DC ku chingwe cha Ethernet, kulola kuti zida zamagetsi ziziyendetsedwa mwachindunji kudzera pa chingwe cha netiweki.
Kusiyana pakati pa ma switch a PoE ndi ma switch okhazikika
Kusiyana kwakukulu pakati pa ma switch a PoE ndi masinthidwe okhazikika ndikuti amathandizira ukadaulo wa PoE. Masinthidwe wamba amatha kutumiza ma siginecha a data ndipo sangathe kupereka mphamvu ku zida. Ndipo ma switch a PoE amatha kutumiza ma siginecha amagetsi ndi data palimodzi kuzipangizo zamaukonde, kupereka magetsi pazidazo. Kusintha wamba kumafuna kugwiritsa ntchito ma adapter owonjezera kapena zingwe kuti apereke magetsi.
Kusintha kwa PoE kungapereke mphamvu zamagetsi ku zipangizo zomwe zimathandizira teknoloji ya PoE, monga mafoni a IP, makamera a intaneti, malo olowera opanda zingwe, etc. Kusintha kwachidziwitso sikungathe kupereka mphamvu kwa zipangizozi.
Chifukwa cha kuthekera kwa switch ya PoE pazida zamagetsi, palibe chifukwa chowonjezera ma adapter kapena zingwe, potero kupulumutsa mtengo wa zida ndikuchepetsa mtengo wa ma cabling.
Mitundu inayi yogwiritsira ntchito ma switch a PoE
A. Mapulogalamu akunyumba
Ma switch a PoE amatha kupereka mphamvu pazida zosiyanasiyana zapanyumba, monga ma rauta opanda zingwe, makamera a netiweki, mafoni a IP, ndi zina zambiri, zomwe zimapangitsa kuti netiweki yakunyumba ikhale yanzeru komanso yosavuta.
B. Ntchito zamalonda
Muzochita zamalonda, ma switch a PoE amatha mphamvu pazida zosiyanasiyana zomwe zimathandizira ukadaulo wa PoE, monga makamera a netiweki, malo olowera opanda zingwe, zikwangwani zamagetsi, ndi zina zotere. Zidazi nthawi zambiri zimafunika kuziyika pamalo apamwamba kapena ovuta kusintha malo, kotero kugwiritsa ntchito ukadaulo wa PoE kumatha kwambiri. chepetsani ntchito yoyika ndi kukonza.
C. Industrial ntchito
M'mafakitale, kusintha kwa PoE kungapereke mphamvu ku zipangizo zosiyanasiyana zamafakitale, monga makamera a mafakitale, masensa, olamulira, ndi zina zotero. Zida zimenezi nthawi zambiri zimafuna kugwira ntchito kwa nthawi yayitali komanso kudalirika kwakukulu, kotero kugwiritsa ntchito luso la PoE kungachepetse mitengo yolephera ndi kukonza ndalama.
D. Maofesi aboma
M'malo aboma, ma switch a PoE amatha kupereka mphamvu ku zida zosiyanasiyana zanzeru, monga zowunikira mwanzeru, zokhoma zitseko zanzeru, zikwangwani zanzeru, ndi zina zotere. Zidazi zimagawidwa m'malo osiyanasiyana, ndipo kugwiritsa ntchito ukadaulo wa PoE kumatha kupeputsa mawaya ndi ntchito yoyika. .
