Itekhnoloji ye-PoE (Amandla phezu kwe-Ethernet) ibe yinxalenye eyimfuneko yezixhobo zenethiwekhi zala maxesha, kwaye ujongano lokutshintsha kwe-PoE alukwazi ukuhambisa idatha kuphela, kodwa kunye nezixhobo ze-terminal zamandla ngentambo yothungelwano efanayo, ngokulula ukwenza lula i-wiring, ukunciphisa iindleko kunye nokuphucula ukusebenza kakuhle kwenethiwekhi. Eli nqaku liza kuhlalutya ngokubanzi umgaqo wokusebenza, iimeko zesicelo kunye neenzuzo ze-PoE switch interface xa kuthelekiswa nojongano lwemveli ukukunceda uqonde ngcono ukubaluleka kobu buchwepheshe ekuhanjisweni kwenethiwekhi.
Isebenza njani iPoE switch interfaces
IUkutshintsha kwePoEi-interface ihambisa amandla kunye nedatha ngaxeshanye ngentambo ye-Ethernet, eyenza i-wiring ibe lula kwaye iphucule ukusebenza kakuhle kokuthunyelwa kwezixhobo. Inkqubo yokusebenza kwayo ikakhulu ibandakanya la manyathelo alandelayo:
Ukufunyanwa kunye nokuhlelwa
Ukutshintsha kwe-PoE kuqala ukubona ukuba isixhobo esixhunyiwe (PD) sixhasa umsebenzi we-PoE, kwaye ichonge ngokuzenzekelayo inqanaba lamandla afunekayo (iKlasi 0 ~ 4) ukuhambelana nokunikezelwa kwamandla okufanelekileyo.
Ukunikezelwa kwamandla kunye nokuhanjiswa kwedatha
Emva kokuqinisekisa ukuba ifowuni yePD iyahambelana, i-PoE switch idlulisela idatha kunye namandla ngaxeshanye ngeebini ezimbini okanye ezine zeentambo eziphothiweyo, ukudibanisa ukunikezelwa kwamandla kunye nokunxibelelana.
Ulawulo lwamandla obukrelekrele kunye nokhuseleko
Ukutshintsha kwe-PoE kunokusasazwa kwamandla, ukukhuselwa komthwalo ogqithisiweyo kunye nemisebenzi yokukhusela i-short-circuit yokuqinisekisa ukusebenza ngokukhuselekileyo kwezixhobo. Xa isixhobo esinikwe amandla sivaliwe, unikezelo lwamandla lwe-PoE luyayeka ngokuzenzekelayo ukuphepha ukuchitha amandla.
Iimeko zesicelo sokutshintsha kwe-PoE
I-PoE switch interfaces isetyenziswa ngokubanzi kwiinkalo ezininzi ngenxa yokulula kunye nokusebenza kakuhle, ngakumbi ekubekweni kweliso lokhuseleko, uthungelwano lwamacingo, izakhiwo ezihlakaniphile kunye ne-intanethi ye-intanethi yezinto.
Inkqubo yokubeka iliso yokhuseleko
Kwintsimi yokuhlolwa kwevidiyo, ukutshintshwa kwe-PoE kusetyenziswe ngokubanzi ukunikezelwa kwamandla kunye nokuhanjiswa kwedatha yeekhamera ze-IP. Itekhnoloji ye-PoE inokwenza lula i-wiring. Akukho mfuneko yokufaka iintambo zombane kwikhamera nganye ngokwahlukeneyo. Intambo yenethiwekhi enye kuphela efunekayo ukugqiba ukunikezelwa kwamandla kunye nokuhanjiswa kwesignali yevidiyo, ephucula kakhulu ukuhanjiswa kunye nokunciphisa iindleko zokwakha. Ngokomzekelo, usebenzisa i-8-port ye-Gigabit PoE switch, unokudibanisa ngokulula iikhamera ezininzi ukuqinisekisa ukusebenza okuzinzile kwamanethiwekhi amakhulu okhuseleko.
Wireless AP Power Supply
Xa uhambisa amanethiwekhi e-Wi-Fi kumashishini okanye kwiindawo zikawonkewonke, ukutshintsha kwe-PoE kunokubonelela ngedatha kunye namandla kwizixhobo ezingenazintambo ze-AP. Ubonelelo lwamandla e-PoE lunokwenza lula i-wiring, luthintele ii-APs ezingenazingcingo ukuba zithintelwe ziindawo ezinesokhethi ngenxa yemicimbi yobonelelo lwamandla, kunye nokuxhasa unikezelo lwamandla lomgama omde, ukwandisa ngokufanelekileyo ukugubungela uthungelwano olungenazingcingo. Umzekelo, kwiindawo ezinkulu zokuthenga, kwizikhululo zeenqwelo moya, iihotele kunye nezinye iindawo, iiswitshi ze-PoE zinokufikelela ngokulula kwi-coverage enkulu engenazingcingo.
Izakhiwo ezihlakaniphile kunye nezixhobo ze-IoT
Kwizakhiwo ezihlakaniphileyo, ukutshintshwa kwe-PoE kusetyenziswa ngokubanzi kwiinkqubo zokulawula ukufikelela, ukukhanya okukhanyayo, kunye nezixhobo zenzwa, ezinceda ukufezekisa ukuzenzekelayo kwe-automation kunye nokusebenza kakuhle kwamandla. Ngokomzekelo, iinkqubo zokukhanyisa ezihlakaniphile zisebenzisa umbane we-PoE, onokufikelela kulawulo lokutshintsha okude kunye nohlengahlengiso lokukhanya, kwaye lusebenza kakuhle kwaye lugcina amandla.
Ujongano lokutshintsha kwePoE kunye nojongano lwemveli
Xa kuthelekiswa nojongano lwemveli, ujongano lokutshintsha kwe-PoE luneenzuzo ezibalulekileyo kwikhebula, ukusebenza kakuhle, kunye nolawulo:
Yenza lula iingcingo kunye nofakelo
I-interface ye-PoE idibanisa idatha kunye nokunikezelwa kwamandla, ukuphelisa imfuno yeentambo zombane ezongezelelweyo, ukunciphisa kakhulu ubunzima be-wiring. I-interfaces yendabuko ifuna i-wiring eyahlukileyo yezixhobo, ezingandisi nje iindleko zokwakha, kodwa zichaphazela i-aesthetics kunye nokusetyenziswa kwendawo.
Ukunciphisa iindleko kunye nobunzima bokulondolozwa
Umsebenzi wokunikezelwa kwamandla okude wokutshintsha kwe-PoE kunciphisa ukuxhomekeka kwiisokethi kunye neentambo zamandla, ukunciphisa i-wiring kunye neendleko zokugcina. Unxibelelwano lwemveli lufuna izixhobo ezongezelelweyo zobonelelo lwamandla kunye nolawulo, ukwandisa ubunzima bokugcinwa.
Ukuguquguquka okuphuculweyo kunye nokuqina
Izixhobo ze-PoE azithintelwa yindawo yezixhobo zombane kwaye zinokusasazwa ngokuguquguqukayo kwiindawo ezikude nezixhobo zombane, ezifana neendonga kunye neesilingi. Xa ukwandisa inethiwekhi, akukho mfuneko yokuqwalasela i-wiring yamandla, ephucula ukuguquguquka kunye nokusabalalisa kwenethiwekhi.
Isishwankathelo
Ukutshintsha kwePoEi-interface ibe sisixhobo esiphambili sokusasazwa kwenethiwekhi yanamhlanje ngenxa yeenzuzo zayo zokudibanisa idatha kunye nonikezelo lwamandla, ukwenza lula iingcingo, ukunciphisa iindleko kunye nokuphucula ukuguquguquka. Ibonise ixabiso elinamandla lesicelo ekubekweni esweni kokhuseleko, uthungelwano lwamacingo, izakhiwo ezihlakaniphile, i-intanethi ye-industrial yeZinto kunye nezinye iinkalo. Kwixesha elizayo, ngophuhliso olukhawulezayo lwe-Intanethi yeZinto, i-edge computing kunye neteknoloji yobukrelekrele bokwenziwa, iiswitshi ze-PoE ziya kuqhubeka zidlala indima ebalulekileyo ekuncedeni izixhobo zenethiwekhi zifezekiseke ngokufanelekileyo, eziguquguqukayo kunye nokuhanjiswa okukrelekrele.
