Ngaphandle kwentambo yenethiwekhi, yintoni enye echaphazela umgama wothumelo lwamandla e-PoE?
I-PoE inokudlulisa idatha ngentambo yenethiwekhi ngelixa inika amandla kwizixhobo ze-terminal ze-PoE ezifana ne-wireless AP, ikhamera yenethiwekhi, ifowuni ye-IP, i-PAD, njl., kunye nomgama wokuhambisa ukuya kwi-100 yeemitha. Ekubeni inkqubo yonikezelo lwamandla e-PoE kulula ukuyifaka kunye ne-plug-and-play, ifanelekile kakhulu ukusetyenziswa kumashishini afana nezixeko ezihlakaniphile kunye nokubeka iliso lokhuseleko.
- Imiba ephambili echaphazela umgama wothumelo lwe-PoE
1-1. Umgangatho wentambo yenethiwekhi
Umgama wokuhanjiswa komqondiso wedatha yeentambo eziqhelekileyo zeCandelo 5 malunga neemitha ezili-100. Ukuqwalasela izinto ezifana nokunciphisa umjelo kubunjineli, i-80-90 yeemitha zithathwa ngokubanzi ukuqinisekisa umgangatho wokwakha. Umgama wothumelo apha ubhekiselele kwinqanaba eliphezulu, elifana ne-100M. Nangona kunjalo, ukuba izinga liyancitshiswa ukuya kwi-10M, umgama wokudluliselwa unokwandiswa ukuya kwi-150-250 yeemitha, kuxhomekeke kumgangatho wentambo yenethiwekhi.
Umgama wonikezelo lwamandla we-PoE unxulumene ngokusondeleyo nezinto zentambo yenethiwekhi. Okuya kusezantsi i-impedance yentambo yenethiwekhi, kokukhona umgama wothumelo ude.
1-2. Ukubekwa kwekhebula kunye nokuchithwa kobushushu
Ukunyuka kweqondo lokushisa kwekhebula kuya kukhokelela ekunciphiseni ukutshatyalaliswa kwesiteshi kunye nokusebenza kokulahleka kokufakwa. Xa ubeka iintambo ze-PoE, impembelelo yokubeka intambo ekugqithiseni ukushisa kufuneka ithathelwe ingqalelo.
Ngoko ke, xa ubeka iintambo, nikela ingqalelo ekuthatheni indlela ehambelana nokutshatyalaliswa kobushushu.
1-3. Ukusebenza kokutshintsha kwePoE
Inethiwekhi eyomeleleyo ayixhomekeke kuphela kumgama wokubonelela ngombane we-PoE, kodwa kunye nomgangatho wothumelo lwenethiwekhi kufuneka uqinisekiswe. Ngokwemigaqo ye-IEEE, ukuba ukuhanjiswa kwentambo yenethiwekhi kudlula iimitha ezili-100, umgangatho wothumelo awunakuqinisekiswa.
Nangona kunjalo, kwezinye iimeko (phantsi koxinzelelo lweendleko), njengaxa ufaka ikhamera, umgama ungadlula i-100 yeemitha. Ukuba umgama awukude kakhulu, ukuseta izinga lokuxhuma kwekhamera kwi-10M kunokwandisa umgama wokuhanjiswa kwe-PoE ukuya kwi-150-250 yeemitha.
Ukuze kuphunyezwe umgama omde wothumelo, i-PoE switch ineemfuno ezingqongqo kwintambo yenethiwekhi kwaye ukusebenza kwayo nayo ibalulekile. Ukuba i-chip yangaphakathi yokutshintsha kwe-PoE inamandla okuziqhelanisa kunye namandla okulawula i-chip anamandla, nokuba izinga lokuhambisa linyanzeliswa ukuba libe yi-10M, ayinakuqinisekisa ukuhanjiswa okuzinzile kweemitha ezingama-250, kunye neemitha ezili-150 azikwazi. kuzuzwa.
Ukuhlangabezana nemfuno yentengiso, i-JHA Tech iye yaphehlelela uluhlu olude lokuhanjiswa kwePoE Switch.
- 2. Amanqaku aphambili
Umbane we-PoE uneemfuno eziphezulu zeengcingo. Umgangatho weentambo zenethiwekhi zihambelana nomgama wothumelo kunye nokuzinza kokuhanjiswa kwe-PoE. Bubudenge ukuthetha ngomgama wothumelo ngaphandle kokuqwalasela iintambo zenethiwekhi. Kwiiprojekthi zokubeka iliso, musa ukugcina iindleko kwiingcingo, ukuze ungalahlekelwa ngaphezu kokufumana kwakho.
