Ubuchwepheshe be-PoE (Amandla phezu kwe-Ethernet) sebuyingxenye ebalulekile yemishini yesimanje yenethiwekhi, futhi isixhumi esibonakalayo sokushintsha se-PoE asikwazi nje ukudlulisa idatha, kodwa futhi namadivaysi agcina amandla ngentambo yenethiwekhi efanayo, ukwenza lula izintambo, ukunciphisa izindleko nokuthuthukisa ukusebenza kahle kokuthunyelwa kwenethiwekhi. Lesi sihloko sizohlaziya ngokugcwele isimiso sokusebenza, izimo zohlelo lokusebenza kanye nezinzuzo zesixhumi esibonakalayo sokushintshwa kwe-PoE uma kuqhathaniswa nokuxhumana okuvamile ukuze sikusize uqonde kangcono ukubaluleka kwalobu buchwepheshe ekusetshenzisweni kwenethiwekhi.
I-PoE switch interface isebenza kanjani
IShintshanisa amasheya PoEisixhumi esibonakalayo sidlulisa amandla nedatha ngesikhathi esisodwa ngekhebula ye-Ethernet, eyenza izintambo zibe lula futhi ithuthukise ukusebenza kahle kokuthunyelwa kwemishini. Inqubo yayo yokusebenza ihlanganisa ikakhulukazi izinyathelo ezilandelayo:
Ukutholwa kanye nezigaba
Iswishi ye-PoE kuqala ithola ukuthi idivayisi exhunyiwe (i-PD) iyawusekela yini umsebenzi we-PoE, futhi ihlonze ngokuzenzakalelayo ileveli yayo yamandla edingekayo (Isigaba 0~4) ukuze ifane nokunikezwa kwamandla okufanelekile.
Ukunikezwa kwamandla kanye nokudluliswa kwedatha
Ngemva kokuqinisekisa ukuthi idivayisi ye-PD iyahambisana, isishintshi se-PoE sidlulisela idatha namandla kanyekanye ngamapheya amabili noma amane ezintambo ezisontekile, ezihlanganisa ukunikezwa kwamandla nokuxhumana.
Ukuphathwa kwamandla okukhaliphile nokuvikela
Amaswishi e-PoE anokusabalalisa amandla, ukuvikela ukugcwala ngokweqile kanye nemisebenzi yokuvikela isifunda esifushane ukuze kuqinisekiswe ukusebenza okuphephile kwemishini. Uma idivayisi enikwe amandla inqanyulwa, ukunikezwa kwamandla kwe-PoE kuyama ngokuzenzakalela ukuze kugwenywe ukumosha amandla.
Izimo zohlelo lokusebenza lokushintsha kwe-PoE
Izixhumanisi zokushintshwa kwe-PoE zisetshenziswa kabanzi emikhakheni eminingi ngenxa yokunethezeka nokusebenza kahle kwazo, ikakhulukazi ekuqapheni ukuphepha, amanethiwekhi angenantambo, izakhiwo ezihlakaniphile nezimo ze-inthanethi Yezinto Yezimboni.
Uhlelo lokuqapha ukuphepha
Emkhakheni wokubhekwa kwevidiyo, ukushintshwa kwe-PoE kusetshenziselwa kakhulu ukunikezwa kwamandla kanye nokudluliswa kwedatha yamakhamera we-IP. Ubuchwepheshe be-PoE bungenza izintambo zibe lula ngempumelelo. Asikho isidingo sokuxhuma izintambo zamandla kukhamera ngayinye ngokuhlukana. Kudingeka ikhebula lenethiwekhi eyodwa kuphela ukuze kuqedelwe ukunikezwa kwamandla kanye nokudluliswa kwesignali yevidiyo, okuthuthukisa kakhulu ukusebenza kahle kokuthunyelwa futhi kunciphisa izindleko zokwakha. Isibonelo, usebenzisa i-8-port ye-Gigabit PoE switch, ungakwazi ukuxhuma kalula amakhamera amaningi ukuze uqinisekise ukusebenza okuzinzile kwamanethiwekhi amakhulu okuphepha.
I-Wireless AP Power Supply
Lapho kusetshenziswa amanethiwekhi e-Wi-Fi kumabhizinisi noma ezindaweni zomphakathi, amaswishi e-PoE anganikeza idatha namandla kumadivayisi angenantambo e-AP. Ukunikezwa kwamandla kwe-PoE kungenza izintambo zibe lula, kugweme ama-AP angenantambo akhawulelwe izindawo ezinesokhethi ngenxa yezinkinga zokuphakelwa kwamandla, futhi kusekele ukuphakelwa kwamandla amabanga amade, kunwebe ngempumelelo ukumbozwa kwamanethiwekhi angenantambo. Isibonelo, ezinxanxatheleni zezitolo ezinkulu, ezikhumulweni zezindiza, emahhotela nakwezinye izindawo, amaswishi e-PoE angakwazi ukufinyelela kalula ukumbozwa okungenantambo kwenani elikhulu.
Izakhiwo ezihlakaniphile namadivayisi we-IoT
Emabhilidini ahlakaniphile, amaswishi e-PoE asetshenziswa kakhulu ezinhlelweni zokulawula ukufinyelela, ukukhanya okukhaliphile, namadivayisi enzwa, okusiza ukufeza ukuzenzekelayo kokwakha kanye nokwenza kahle kwamandla. Isibonelo, amasistimu okukhanyisa ahlakaniphile asebenzisa amandla e-PoE, angafinyelela isilawuli sokushintshwa kwesilawuli kude nokulungiswa kokukhanya, futhi isebenza kahle kakhulu futhi yonga amandla.
I-PoE switch interface kanye ne-interface yendabuko
Uma kuqhathaniswa nokuxhumana okuvamile, izixhumanisi zokushintshwa kwe-PoE zinezinzuzo ezibalulekile ekufakweni kwekhebula, ukusebenza kahle kokuthunyelwa, nokuphatha:
Yenza izintambo zibe lula nokufaka
I-interface ye-PoE ihlanganisa idatha kanye nokunikezwa kwamandla, kuqeda isidingo sezintambo zamandla ezengeziwe, kunciphisa kakhulu ubunzima bezintambo. Ukuxhumana okuvamile kudinga izintambo ezihlukene zamadivayisi, ezingagcini nje ngokunyusa izindleko zokwakha, kodwa futhi ezithinta ubuhle nokusetshenziswa kwendawo.
Yehlisa izindleko nobunzima bokunakekela
Umsebenzi wokunikezwa kwamandla okukude wamaswishi e-PoE wehlisa ukuncika kumasokhethi nezintambo zikagesi, wehlise izindleko zezintambo nezokulungisa. Izixhumi ezibonakalayo zendabuko zidinga okokusebenza okuphakelwa kukagesi okwengeziwe nokuphathwa, okwandisa inkimbinkimbi yokulungiswa.
Ukuvumelana nezimo okuthuthukisiwe nokuqina
Imishini ye-PoE ayikhawulelwe indawo yezinto zikagesi futhi ingatshalwa kalula ezindaweni ezikude nezinto zikagesi, njengezindonga nosilingi. Uma unweba inethiwekhi, asikho isidingo sokucabangela i-wiring yamandla, okuthuthukisa ukuguquguquka nokulinganisa kwenethiwekhi.
Isifinyezo
Shintshanisa amasheya PoEisixhumi esibonakalayo sesiphenduke idivayisi eyinhloko yokuthunyelwa kwenethiwekhi yesimanje ngenxa yezinzuzo zayo zokuhlanganisa idatha namandla kagesi, ukwenza izintambo zibe lula, ukunciphisa izindleko kanye nokuthuthukisa ukuguquguquka. Ibonise inani eliqinile lesicelo ekuqaphelweni kwezokuphepha, amanethiwekhi angenantambo, izakhiwo ezihlakaniphile, i-inthanethi yezimboni Yezinto kanye neminye imikhakha. Esikhathini esizayo, ngokuthuthuka okusheshayo kwe-inthanethi Yezinto, i-edge computing kanye nobuchwepheshe bobuhlakani bokwenziwa, amaswishi e-PoE azoqhubeka nokudlala indima ebalulekile ekusizeni imishini yenethiwekhi ukuthi ifinyelele ukuthunyelwa okuphumelelayo, okuguquguqukayo nokuhlakaniphile.
