Itekhnoloji yePoE (Power over Ethernet) ibe yinxalenye ebalulekileyo yezixhobo zenethiwekhi zanamhlanje, kwaye i-PoE switch interface ayinako ukudlulisa idatha kuphela, kodwa nezixhobo ze-power terminal ngentambo efanayo yenethiwekhi, okwenza kube lula ukufakelwa kweentambo, ukunciphisa iindleko kunye nokuphucula ukusebenza kakuhle kokuthunyelwa kwenethiwekhi. Eli nqaku liza kuhlalutya ngokubanzi umgaqo wokusebenza, iimeko zesicelo kunye neenzuzo ze-PoE switch interface xa kuthelekiswa ne-interfaces zendabuko ukukunceda uqonde ngcono ukubaluleka kwale teknoloji ekusetyenzisweni kwenethiwekhi.
Indlela esebenza ngayo i-PoE switch interfaces
IUtshintsho lwePoEI-interface ithumela amandla kunye nedatha ngaxeshanye ngentambo ye-Ethernet, nto leyo eyenza kube lula ukufakelwa kwentambo kwaye iphucule ukusebenza kakuhle kokufakwa kwezixhobo. Inkqubo yayo yokusebenza ibandakanya ikakhulu la manyathelo alandelayo:
Ukuchonga kunye nokwahlulahlula
Iswitshi yePoE iqala ibone ukuba isixhobo esiqhagamshelweyo (PD) siyawuxhasa na umsebenzi wePoE, ize ichonge ngokuzenzekelayo inqanaba lamandla afunekayo (iKlasi 0~4) ukuze ihambelane nombane ofanelekileyo.
Ubonelelo lwamandla kunye nokudluliselwa kwedatha
Emva kokuqinisekisa ukuba isixhobo sePD siyahambelana, iswitshi sePoE sithumela idatha kunye namandla ngaxeshanye ngeentambo ezimbini okanye ezine ezijijekileyo, sidibanisa umbane kunye nonxibelelwano.
Ulawulo lwamandla olukrelekrele kunye nokhuseleko
Iiswitshi zePoE zinosasazo lwamandla, ukhuseleko lokugqithisa kunye nemisebenzi yokukhusela i-short-circuit ukuqinisekisa ukusebenza ngokukhuselekileyo kwezixhobo. Xa isixhobo esisebenza ngamandla sinqanyuliwe, umbane wePoE uyayeka ngokuzenzekelayo ukuphepha ukuchitha amandla.
Iimeko zesicelo sokutshintsha i-PoE interface
Ii-PoE switch interfaces zisetyenziswa kakhulu kwiindawo ezininzi ngenxa yokulula nokusebenza kakuhle kwazo, ingakumbi ekujongeni ukhuseleko, iinethiwekhi ezingenazingcingo, izakhiwo ezikrelekrele kunye neemeko ze-intanethi yezinto zoshishino.
Inkqubo yokubeka iliso kukhuseleko
Kwicandelo lokujonga ividiyo, iiswitshi zePoE zisetyenziswa kakhulu ekunikezelweni kombane kunye nokudluliselwa kwedatha kweekhamera ze-IP. Itekhnoloji yePoE inokwenza lula ukufakelwa kweentambo. Akukho mfuneko yokufakelwa iintambo zombane kwikhamera nganye ngokwahlukeneyo. Kufuneka intambo enye yenethiwekhi ukuze kugqitywe ukuhanjiswa kombane kunye nokudluliselwa kwesignali yevidiyo, nto leyo ephucula kakhulu ukusebenza kakuhle kokufakwa kwayo kwaye inciphise iindleko zokwakha. Umzekelo, usebenzisa iswitshi yeGigabit PoE enamachweba asi-8, ungaqhagamshela ngokulula iikhamera ezininzi ukuqinisekisa ukusebenza okuzinzileyo kweenethiwekhi ezinkulu zokhuseleko.
Ubonelelo lwaMandla lwe-AP olungenazingcingo
Xa kusetyenziswa iinethiwekhi zeWi-Fi kumashishini okanye kwiindawo zikawonke-wonke, iiswitshi zePoE zinokubonelela ngedatha kunye namandla kwizixhobo ze-AP ezingenazingcingo. Umbane wePoE unokwenza lula ukufakelwa kweentambo, uthintele ukuba ii-AP ezingenazingcingo zithintelwe ziindawo zesokhethi ngenxa yeengxaki zombane, kwaye uxhase umbane ohamba umgama omde, ukwandisa ngempumelelo ukugubungela iinethiwekhi ezingenazingcingo. Umzekelo, kwiindawo ezinkulu zokuthenga, kwizikhululo zeenqwelo-moya, kwiihotele nakwezinye iindawo, iiswitshi zePoE zinokufikelela ngokulula ukugubungela okukhulu okungenazingcingo.
Izakhiwo ezikrelekrele kunye nezixhobo ze-IoT
Kwizakhiwo ezikrelekrele, iiswitshi zePoE zisetyenziswa kakhulu kwiinkqubo zokulawula ukufikelela, izibane ezikrelekrele, kunye nezixhobo zesensor, nto leyo enceda ekufezekiseni ukwenziwa kwezinto ngokuzenzekelayo kunye nokusebenza kakuhle kwamandla. Umzekelo, iinkqubo zokukhanyisa ezikrelekrele zisebenzisa umbane wePoE, onokufezekisa ulawulo lweswitshi olukude kunye nokulungiswa kokukhanya, kwaye usebenza kakuhle kwaye wonga amandla.
Ujongano lokutshintsha kwePoE kunye nojongano lwendabuko
Xa kuthelekiswa neendlela zokunxibelelana zemveli, iindlela zokunxibelelana ze-PoE switch zinezibonelelo ezibalulekileyo ekunxibelelaneni ngentambo, ukusebenza kakuhle kokuthunyelwa, kunye nolawulo:
