一.Ingabe ukushintsha kwe-PoE inkulu kuba ngcono?
Njengoba kunamadivayisi amaningi anamandla aphezulu kumishini yokuqapha yamanje, abakhiqizi bokushintsha bavame ukuthuthukisa amaswishi e-PoE ngamandla aphezulu. Kodwa-ke, imikhiqizo eminingi emakethe iphishekela kuphela ukuhlinzekwa kwamandla aphelele, futhi ayicabangi inani lamachweba. Lapho amandla enyuswa, izindleko zizonke zemishini nazo zizokhuphuka, ngakho-ke izindleko zokuthenga zizokwenyuka ngokwemvelo. Ngakho-ke, lapho abasebenzisi bethenga, kufanele bakhethe ukushintshwa okufanele ngokuya ngesimo sangempela, hhayi amandla aphezulu, okungcono.
二.Yiziphi izingozi ze-PoE phakathi nenqubo yokunikezwa kwamandla?
1. Amandla anganele
820.af amandla okukhiphayo ajwayelekile e-PoE angaphansi kuka-15.4w, okwanele ku-IPC evamile, kodwa ku-PD yamandla aphezulu, amandla okukhiphayo awakwazi ukuhlangabezana nezimfuneko;
2. Ubungozi bugxile kakhulu
Ngokuvamile, ukushintsha kwe-PoE kuzonikeza amandla kuma-IPC amaningi angaphambili ngasikhathi sinye. Uma imodyuli yokunikezwa kwamandla kagesi yehluleka, izothinta umsebenzi wawo wonke amakhamera, futhi ubungozi bugxile kakhulu;
3. Izisetshenziswa eziphezulu kanye nezindleko zokuyilungisa
Uma kuqhathaniswa nezinye izindlela zokuphakelwa kukagesi, ubuchwepheshe bokuhlinzeka ngogesi be-PoE buzokhuphula umsebenzi wokulungisa ngemva kokuthengisa. Ngokombono wokuphepha, ukuzinza kokunikezwa kwamandla okukodwa kungcono kakhulu.
三.Lithini ibanga eliphephile lokudlulisa amandla e-PoE?
Ibanga eliphephile lokudlulisa amandla e-POE lingamamitha ayi-100, futhi kuyanconywa ukusebenzisa intambo yenethiwekhi yethusi eyisihlanu egcwele. I-Direct current ingadluliselwa kude kakhulu ngezintambo ezijwayelekile ze-Ethernet, kungani-ke ibanga lokudlulisela lilinganiselwe kumamitha ayi-100? Iqiniso liwukuthi ibanga eliphezulu lokudlulisa le-switch ye-PoE lincike kakhulu ebangeni lokudluliswa kwedatha. Uma ibanga lokudlulisela lingaphezu kwamamitha ayi-100, ukulibaziseka kwedatha nokulahlekelwa kwephakethe kungase kwenzeke. Ngakho-ke, ohlelweni lwangempela lokwakha, ibanga lokudlulisela akufanele lidlule amamitha ayi-100. Kodwa-ke, akhona kakade amanye ama-switch e-PoE angafinyelela ibanga lokudlulisela lamamitha angu-250, anele ukunikezwa kwamandla okude. Kukholakala futhi ukuthi ngokuthuthukiswa kobuchwepheshe bokuhlinzeka ngogesi we-PoE esikhathini esizayo esiseduze, ibanga lokudlulisela lizonwetshwa kakhulu.
四.Ingabe kufanele ngithenge iswishi ye-PoE evamile? Zingasetshenziswa ezingajwayelekile?
Khetha okujwayelekile noma okungajwayelekile, lokhu kuncike kakhulu ekunikezeni amandla i-AP, IP
Ikhamera isekela yiphi i-voltage? 48, 24, 12v. Uma kungu-48v, udinga ukukhetha ukushintshwa kwe-PoE okujwayelekile; uma i-24 noma i-12v, udinga ukuthola ukushintshwa okuhambisanayo okungajwayelekile, yiqiniso, okujwayelekile kungenzeka, kodwa uma uthenga okujwayelekile, udinga ukuhlonywa nge-PD splitter.
Kusukela encazelweni, singabona ukuthi ngezinye izikhathi amaswishi angajwayelekile ayatholakala, futhi intengo izoba phansi uma kuqhathaniswa, kodwa sisakukhumbuza ukuthi uthenge ukushintsha okujwayelekile. Ngenxa yokuthi ukushintshwa okungajwayelekile akunayo i-chip ye-PoE futhi ayiboni idivayisi, kulula ukwenza isifunda esifushane ukushisa idivayisi, okungase kushise ichweba ekukhanyeni, noma kubangele umlilo esimweni esinzima; kuyilapho iswishi evamile izohlolwa uma ivuliwe ukuze kugwenywe ukushisa idivayisi.
五.Ungakhetha kanjani inkinobho ye-PoE yokuqapha ukuphepha nokumbozwa okungenantambo?
Kunezinhlobo eziningi zokushintshwa kwe-PoE, kusukela ku-100M kuya ku-1000M, kuya ku-gigabit egcwele, kanye nomehluko phakathi kwezinhlobo ezingalawulwa neziphethwe, kanye nomehluko enanini lamachweba ahlukene. Uma ufuna ukukhetha ukushintshwa okufanelekile, udinga ukucatshangelwa okubanzi nokuphelele. . Thatha iphrojekthi edinga ukuqapha okunencazelo ephezulu njengesibonelo.
1. Khetha iswishi ye-PoE evamile
2. Khetha iswishi engu-100M noma engu-1000M
Esixazululweni sangempela, kuyadingeka ukuhlanganisa inombolo yamakhamera, futhi ukhethe imingcele efana nokulungiswa kwekhamera, isilinganiso sebhithi, nenombolo yozimele. Abakhiqizi bemishini yokuqapha bazohlinzeka ngamathuluzi okubala umkhawulokudonsa ochwepheshe, futhi abasebenzisi bangasebenzisa amathuluzi ukubala umkhawulokudonsa odingekayo futhi bakhethe ukushintsha okufanelekile kwe-PoE.
3. Khetha i-af noma kuswishi ye-PoE evamile
Khetha ngokuya ngamandla emishini yokuqapha. Isibonelo, uma kusetshenziswa ikhamera yomkhiqizo owaziwayo, amandla angu-12W max. Kulokhu, ukushintsha kwezinga le-af lidinga ukukhethwa. Amandla ekhamera yedome enencazelo ephezulu angu-30W max. Kulokhu, kuyadingeka ukusebenzisa inkinobho esezingeni.
Okwesine, khetha inombolo yezimbobo ekushintsheni
Ngokuya ngenani lezimbobo, ukushintsha kwe-PoE kungahlukaniswa ngezimbobo ezingu-4, izimbobo ezingu-8, izimbobo ezingu-16 nezimbobo ezingu-24, njll., ezingaqapha ngokugcwele amandla, ubuningi, indawo yesisetshenziswa, ukushintsha ukunikezwa kwamandla nokukhetha amanani.
