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 sekuyindlela ephumelelayo yokuhlinzeka ngamandla kanye 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 yenza kanjani i-POEshintshaamandla lawa 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.
I-POEshintshaohlelweni lwe-POE lungasebenza 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 ekuqashweni kwezokuphepha. ukufakwa nokuphatha uhlelo.
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-ke amaswishi e-POE namaswishi e-POE+ asetshenziswa kakhulu.
Ukunikezwa kwamandla kwe-POE cishe kungamaphuzu olwazi angenhla, mayelana neshintshauchungechunge kulokhu okushiwo ngenhla e-Shenzhen HDV Phoelectron Technology Ltd. ingeyesigaba esidumile semikhiqizo yokuxhumana, efana nale: Ethernetshintsha, Isiteshi seFibershintsha, Isiteshi se-Ethernet Fibershintsha, njll., amaswishi angenhla angasetshenziswa ezindaweni ezihlukahlukene, ukunikeza ukukhetha okwengeziwe kubasebenzisi abanezidingo ezahlukene, siyakwamukela ukuqonda, sizohlinzeka ngesevisi yekhwalithi engcono kakhulu.
