Kodi POE Power Over Ethernet ndi chiyani? - Network Technology Guide
Power over Ethernet (PoE) ndiukadaulo wosintha masewera pama network amakono. Imalola deta ndi mphamvu kuyenda kudzera mu chingwe chimodzi cha Ethernet. Izi zimapangitsa kuti zida zolumikizirana ndi magetsi zikhale zosavuta komanso zogwira mtima m'malo ambiri.
PoE ndiyofunikira pakukhazikitsa maukonde, yopereka njira yosavuta komanso yotsika mtengo pazida zamagetsi. Izi zikuphatikiza makamera a IP, malo olowera opanda zingwe, mafoni a VoIP, ndi masensa anzeru.
PoE imalola kusintha kwa Ethernet kapena zida zina zamagetsi zamagetsi mwachindunji. Izi zikutanthauza kuti palibe chifukwa chowonjezera magetsi kapena ma adapter. Zimapangitsa kukhazikitsa kukhala kosavuta, kumachepetsa chisokonezo, ndikuwonjezera magwiridwe antchito a netiweki, makamaka pomwe malo opangira magetsi ndi ovuta kupeza.

Kodi PoE Imagwira Ntchito Motani?
| PoE Standard | Kutumiza Mphamvu Kwambiri |
| 802.3af (PoE) | 15.4 watts |
| 802.3at (PoE+) | 30 watts |
| 802.3bt (PoE++) | 90 watts |
Miyezo ya PoE ndi Zigawo
IEEE 802.3af (PoE)
Muyezo wa IEEE 802.3af, womwe umadziwikanso kuti PoE, unali woyamba kugunda kwambiri. Imalola zida kukwera mpaka ma watts a 15.4, okhala ndi ma watts osachepera 12.95 pa chipangizocho.
IEEE 802.3at (PoE+)
IEEE 802.3at standard, kapena PoE+, idakweza mphamvu mpaka 30 watts. Izi zikutanthauza kuti zida monga makamera a PTZ ndi malo opanda zingwe atha kupeza mphamvu zambiri.
IEEE 802.3bt (PoE++ kapena 4PPoE)
Muyezo waposachedwa, IEEE 802.3bt, kapena PoE++ kapena 4PPoE, umapita motalikirapo. Imalola mphamvu yofikira ma watts 90, ndikupangitsa kuti ikhale yabwino pazida zamphamvu kwambiri monga magetsi a LED ndi zida zamafakitale.
Makalasi Amphamvu ndi Zofotokozera Zawo
Miyezo ya PoE ili ndi magulu amphamvu osiyanasiyana. Maphunzirowa amachokera ku Class 0 mpaka 8, iliyonse ili ndi mphamvu zake. Nayi tebulo lowonetsa mphamvu za kalasi iliyonse:
| Gulu la Mphamvu | Mphamvu Yochuluka pa Gwero la Mphamvu | Mphamvu Zochepa pa Chipangizo Chamagetsi |
| Kalasi 0 | 15.4W | 0,44 W - 12.95 W |
| Kalasi 1 | 4 mu | 0,44 W - 3.84 W |
| Kalasi 2 | 7 W | 3.84 W - 6.49 W |
| Kalasi 3 | 15.4W | 6.49 W - 12.95 W |
| Kalasi 4 | 30 W | 12.95 W - 25.5 W |
| Kalasi 5 | 45 w | 25.5 W - 40 W |
| Kalasi 6 | 60 W | 40 W - 51 W |
| Kalasi 7 | 75 w | 51 W - 62 W |
| Kalasi 8 | 90 w | 62 W - 71 W |
Kugwiritsa ntchito PoE : PoE Devices
Ukadaulo wamphamvu pa Ethernet (PoE) tsopano ndiwofala mu ma network ambiri. Amagwiritsidwa ntchito pazida ndi machitidwe osiyanasiyana. Kuchokera ku mphamvu ya ndakatulo pa zipangizo za ethernet kupita ku mphamvu ya ndakatulo pa mapulogalamu a ethernet, PoE yasintha momwe timapangira mphamvu ndikugwirizanitsa magawo osiyanasiyana a mphamvu za ndakatulo pa machitidwe a ethernet.
Kugwiritsidwa ntchito kwakukulu kwa PoE kuli mkati Makamera a IP ndi machitidwe owunikira. Zida izi zimapeza mphamvu ndi data kudzera mu chingwe chimodzi cha Ethernet. Izi zimapangitsa kukhazikitsa kukhala kosavuta ndikuchotsa kufunikira kwa magwero amagetsi owonjezera.
PoE ndiyonso yofunika kwambiri Mafoni a Voice over IP (VoIP).. Zimathandizira mafoniwa kugwira ntchito limodzi bwino m'maofesi. Izi zimapangitsa kulankhulana bwino ndi mgwirizano.
PoE ndi yabwino kwa malo olowera opanda zingwe ndi masensa a IoT nawonso. Mphamvu za ndakatulo izi pazida za ethernet zitha kukhazikitsidwa paliponse popanda kufunikira magetsi. Izi ndichifukwa choti PoE imatumiza zonse ziwiri ndi mphamvu pa chingwe chimodzi cha Ethernet. Ndiwoyenera ku nyumba zanzeru, malo ogulitsa mafakitale, ndi machitidwe a IoT.
| PoE-Powered Chipangizo | Kugwiritsa ntchito |
| Makamera a IP | Kuwunika ndi chitetezo machitidwe |
| Mafoni a VoIP | Kulumikizana kogwirizana m'maofesi |
| Wireless Access Points | Kulumikizana opanda zingwe m'nyumba zanzeru ndi maukonde a IoT |
| Masensa a IoT | Kuyang'anira ndi automation mu mafakitale ndi malonda |
Ubwino Wogwiritsa Ntchito PoE
PoE, kapena Power over Ethernet, ndiukadaulo wapaintaneti wokhala ndi maubwino ambiri. Imasavuta kukhazikitsa ndikuwonjezera mphamvu zamagetsi. Izi zimapangitsa kukhala kusankha kwapamwamba kwa zida zamagetsi mumanetiweki.
Mphamvu imodzi yayikulu ya ndakatulo pa phindu la ethernet ndi Kutumiza deta ndi mphamvu kudzera mu chingwe chimodzi cha Efaneti. Izi zimachepetsa kuchulukitsitsa ndikupangitsa kukhazikitsa kukhala kosavuta. Kuphatikiza apo, kugwiritsa ntchito mphamvu kwa poe kumatanthauza kugwiritsa ntchito mphamvu pang'ono, kupulumutsa ndalama pakapita nthawi.
Mphamvu ina ya ndakatulo kuposa mwayi wa ethernet ndi wake kusinthasintha. Zipangizo zimatha kupita kumene zikufunika, osafuna magetsi. Kusinthasintha uku ndikwabwino pakukhazikitsa malo opanda zingwe, makamera a IP, ndi mafoni a VoIP.
Pomaliza, poe kusungitsa ndalama ndi kuphatikiza kwakukulu. Imapulumutsa pa kuyika ndi kusungitsa ndalama posafuna makina apadera amagetsi. Izi zimapangitsa PoE kukhala yosangalatsa kwa mabizinesi amitundu yonse, akulu kapena ang'onoang'ono.
Kugwiritsa ntchito PoE kungapangitse kukhazikitsidwa kwa maukonde kukhala kosavuta, kuwongolera kugwiritsa ntchito mphamvu, ndikusunga ndalama. Ndi kusankha mwanzeru ntchito zambiri.
