I-POE Power Supply

Ngaphansi komkhuba wokuthuthukiswa kwe-inthanethi yayo yonke into yokwakha umhlaba ohlakaniphile wezinto, isidingo sabasebenzisi samadivayisi we-IoT siyakhula, futhi ukushintsha kwe-POE sekube yindlela ephumelelayo yokuhlinzeka ngamandla nokudluliswa kwedatha kumadivayisi we-PD ngokusebenzisa izintambo zenethiwekhi.Ukushintsha kwe-PoE kuvumela amadivayisi afana namafoni e-IP, amakhamera we-IP, izindawo zokufinyelela ezingenantambo, noma ukukhanya kwe-POE ukuthola idatha namandla ngekhebula lenethiwekhi eyodwa, okuqeda isidingo sentambo yamandla ehlukile.Ngakho-ke i-POE ishintsha kanjani amandla kulawa madivayisi?Ingabe idala umonakalo kumadivayisi axhunyiwe?Leli phepha lizodingida uchungechunge lwezinkinga ngokuningiliziwe.
Yiziphi izindinganiso ezilandelwa Amandla phezu kwe-Ethernet?Ukubuka konke okujwayelekile kokunikezwa kwamandla kwe-POE.
Ukushintsha kwe-POE ohlelweni lwe-POE kungasebenza njengedivaysi yokuphakela amandla (i-PSE), ngokuya ngamazinga ahlukene wokuphakelwa kukagesi we-Ethernet wemishini yokwamukela (PD) yokuphakelwa kukagesi, ikhaya losizo, ibhizinisi, ikhampasi, izitolo ezinkulu nezinye izindawo ukufakwa nokuphathwa kwesistimu yokuqapha ukuphepha.
Kufanele kuqashelwe ukuthi amazinga e-IEEE 802.3af kanye ne-IEEE 802.3at angamandla phezu kwamazinga e-Ethernet angasekelwa amadivayisi amaningi e-PD emakethe, ngakho ukushintsha kwe-POE kanye nokushintsha kwe-POE+ kusetshenziswa kabanzi.
Ukunikezwa kwamandla ka-POE cishe kungamaphoyinti olwazi angenhla, mayelana nochungechunge lokushintshwa okukhulunywe ngenhla e-Shenzhen HDV Phoelectron Technology Ltd. ingeyesigaba esidumile semikhiqizo yokuxhumana, efana nale: switch ye-Ethernet, switch yeFiber Channel, switch ye-Ethernet Fiber Channel, njll. ., amaswishi angenhla angasetshenziswa ezindaweni ezihlukahlukene, ukunikeza ukukhetha okwengeziwe kubasebenzisi abanezidingo ezahlukene, wamukelekile ukuqonda, sizohlinzeka ngesevisi yekhwalithi engcono kakhulu.
