Ubonelelo lwaMandla lwePOE

Ngaphantsi kwendlela yophuhliso ye-Intanethi yayo yonke into yokwakha ilizwe elikrelekrele lezinto, imfuno yabasebenzisi yezixhobo ze-IoT iyanda, kwaye iiswitshi ze-POE ziye zaba yindlela esebenzayo yokubonelela ngamandla kunye nokuhanjiswa kwedatha kwizixhobo zePD ngokusebenzisa iintambo zenethiwekhi. Ukutshintsha kwe-PoE kuvumela izixhobo ezifana neefowuni ze-IP, iikhamera ze-IP, iindawo zokungena ezingenazintambo, okanye ukukhanya kwe-POE ukufumana idatha kunye namandla ngekhebula lomnatha omnye, ukuphelisa imfuno yentambo yamandla eyahlukileyo. Ke yenza njani iPOEtshintshaamandla ezi zixhobo? Ngaba yenza umonakalo kwizixhobo ezixhunyiwe? Eli phepha liza kuxoxa ngoluhlu lweengxaki ngokubanzi.
Yeyiphi imigangatho elandelwa yi-Power over Ethernet? POE isishwankathelo somgangatho wobonelelo lwamandla.
POEtshintshakwinkqubo ye-POE inokusebenza njengesixhobo sonikezelo lwamandla (PSE), ngokwemigangatho eyahlukeneyo yonikezelo lwamandla e-Ethernet yokuphela kokufumana (PD) izixhobo zonikezelo lwamandla, ikhaya loncedo, ishishini, ikampasi, iivenkile zokuthenga kunye nezinye iindawo kwindawo yokubeka iliso yokhuseleko. ufakelo lwenkqubo nolawulo.
Kufuneka kuqatshelwe ukuba i-IEEE 802.3af kunye ne-IEEE 802.3at imigangatho ingamandla phezu kwemigangatho ye-Ethernet enokuxhaswa ngamadivayisi amaninzi e-PD kwiimarike, ngoko ke ii-POE zokutshintsha kunye ne-POE + zisetyenziswa ngokubanzi.
Unikezelo lwamandla lwePOE luqikelelwa kula manqaku olwazi angasentla, malunga netshintshaseries kukhankanywe ngasentla e Shenzhen HDV Phoelectron Technology Ltd. yeyodidi oludumileyo lweemveliso zonxibelelwano, ezifana: Ethernettshintsha, Umjelo weFayibhatshintsha, Ethernet Fiber Channeltshintsha, njl., utshintsho olungentla lunokusetyenziswa kwiindawo ezahlukeneyo, ukunika ukhetho olungakumbi kubasebenzisi abaneemfuno ezahlukeneyo, bamkelekile ukuba baqonde, siya kubonelela ngenkonzo esemgangathweni.
