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 yindawo 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 elilodwa lomnatha, ukuphelisa imfuno yentambo yamandla eyahlukileyo.Ke i-POE itshintsha njani amandla 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.
Ukutshintsha kwe-POE kwinkqubo ye-POE inokusebenza njengesixhobo sonikezelo lwamandla (PSE), ngokwemigangatho eyahlukeneyo yonikezelo lwamandla e-Ethernet yesixhobo sokufumana umbane (PD) izixhobo zokubonelela ngombane, ikhaya loncedo, ishishini, ikhampasi, iindawo zokuthenga kunye nezinye iindawo kwindawo. Ufakelo nolawulo lwenkqubo yokubeka iliso yokhuseleko.
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 e-POE luqikelelo lwamanqaku olwazi angasentla, malunga noluhlu lokutshintsha kwezi ngasentla zikhankanywe kwi-Shenzhen HDV Phoelectron Technology Ltd. yeyodidi oludumileyo lweemveliso zonxibelelwano, ezinje: iswitsha ye-Ethernet, iswitsha yeFayibha Channel, iswitsha yeFayibha ye-Ethernet, njl. ., Ukutshintsha oku ngasentla kunokusetyenziswa kwiindawo ezahlukeneyo, ukubonelela ukhetho oluninzi kubasebenzisi abaneemfuno ezahlukeneyo, bamkelekile ukuba baqonde, siya kubonelela ngenkonzo esemgangathweni.
