Ngaphandle kwentambo yenethiwekhi, yini enye ethinta ibanga lokudluliswa kwamandla e-PoE?
I-PoE ingadlulisela idatha ngekhebula yenethiwekhi kuyilapho ihlinzeka ngamandla kumadivayisi etheminali e-PoE njenge-wireless AP, ikhamera yenethiwekhi, ifoni ye-IP, i-PAD, njll., ngebanga lokudlulisela elingafika kumamitha ayi-100. Njengoba uhlelo lokuphakelwa kukagesi lwe-PoE kulula ukulufaka nokuluxhuma futhi ludlale, lufaneleka kakhulu ukusetshenziswa ezimbonini ezifana namadolobha ahlakaniphile nokuqapha ezokuphepha.
- Izinto ezisemqoka ezithinta ibanga lokudluliswa kwe-PoE
1-1. Ikhwalithi yekhebula yenethiwekhi
Ibanga lokudlulisa isignali yedatha yezintambo ezijwayelekile zeSigaba 5 cishe lingamamitha ayi-100. Uma kucatshangelwa izici ezifana nokuncishiswa kwesiteshi kubunjiniyela, amamitha angu-80-90 ngokuvamile athathwa ukuze kuqinisekiswe ikhwalithi yokwakha. Ibanga lokudlulisela lapha libhekisela esilinganisweni esiphezulu, esifana ne-100M. Kodwa-ke, uma izinga lehliswa libe ngu-10M, ibanga lokudlulisela linganwetshwa libe ngamamitha angu-150-250, kuye ngekhwalithi yekhebula lenethiwekhi.
Ibanga lokunikezwa kwamandla kwe-PoE lihlobene eduze nezinto zekhebula lenethiwekhi. Ukuncipha kwe-impedance yentambo yenethiwekhi, ibanga lokudlulisela liba lide.
1-2. Ukubekwa kwekhebula kanye nokukhishwa kokushisa
Ukwenyuka kwezinga lokushisa lekhebula kuzoholela ekwehleni kokumiswa kwesiteshi nokusebenza kokulahlekelwa kokufakwa. Lapho ubeka izintambo ze-PoE, umthelela wekhebula elibekwe ekushiseni kokushisa kufanele ucatshangelwe.
Ngakho-ke, lapho ubeka izintambo, qaphela ukwamukela indlela evumela ukuchithwa kokushisa.
1-3. Ukusebenza kokushintsha kwe-PoE
Inethiwekhi eqinile ayincikile kuphela ebangeni lokuphakela amandla e-PoE, kodwa futhi nekhwalithi yokudlulisa inethiwekhi kufanele iqinisekiswe. Ngokwemithetho ye-IEEE, uma ukudluliswa kwentambo yenethiwekhi kudlula amamitha ayi-100, ikhwalithi yokudlulisela ingase ingaqinisekisiwe.
Nokho, kwezinye izimo (ngaphansi kwengcindezi yezindleko), njengalapho ufaka ikhamera, ibanga lingadlula amamitha ayi-100. Uma ibanga lingekude kakhulu, ukusetha izinga lokuxhuma kwekhamera ku-10M kunganweba ibanga lokudlulisela le-PoE libe ngamamitha angu-150-250.
Ukuze kuzuzwe ibanga elide lokudlulisela, ukushintshwa kwe-PoE kunezidingo eziqinile kukhebuli yenethiwekhi futhi nokusebenza kwayo nakho kubalulekile. Uma i-chip yokushintsha yangaphakathi ye-switch ye-PoE inekhono elimpofu lokuzijwayela futhi amandla okuphatha chip amandla aliqinile, ngisho noma izinga lokudlulisela liphoqeleka ukuba libe yi-10M, alikwazi ukuqinisekisa ukudluliswa okuzinzile kwamamitha angu-250, ngisho namamitha angu-150 awakwazi. kuzuzwe.
Ukuze kuhlangatshezwane nesidingo semakethe, i-JHA Tech yethule uchungechunge lwe-PoE Switch yokudlulisela amabanga amade.
- 2. Amaphuzu abalulekile
Ukunikezwa kwamandla kwe-PoE kunezidingo eziphezulu zezintambo. Izinga lezintambo zenethiwekhi lihlobene nebanga lokudlulisela kanye nokuzinza kokudlulisela kwe-PoE. Kuwubuwula ukukhuluma ngebanga lokudlulisela ngaphandle kokucabangela izintambo zenethiwekhi. Emaphrojekthini wokuqapha, ungalondolozi izindleko ezintanjeni, ukuze ungalahlekelwa ngaphezu kwalokho okuzuzayo.
