Masinthidwe amagwiritsidwa ntchito kwambiri pama projekiti omwe afooka, makamakaKusintha kwa POE.POE imatchedwanso makina opangira magetsi amdera lanu (POL, Power over LAN) kapena Active Ethernet (Active Ethernet), nthawi zina amatchedwa Power over Ethernet.Uwu ndiye muyeso waposachedwa kwambiri wotumizira nthawi imodzi deta ndi mphamvu yamagetsi pogwiritsa ntchito zingwe zomwe zilipo kale za Efaneti, ndikusunga kugwirizana ndi makina ndi ogwiritsa ntchito a Ethernet.Ndiye, timasankha bwanji kusintha kwa POE?

1. Ganizirani mphamvu ya zida zanu

Mofananamo, sankhani chosinthira cha PoE chokhala ndi mphamvu zambiri.Ngati mphamvu ya zida zanu ili pansi pa 15W, ndiye sankhani switch ya PoE yomwe imathandizira mulingo wa 802.3af.Ngati mphamvuyo ndi yayikulu kuposa 15W, sankhani chosinthira champhamvu kwambiri chokhala ndi 802.3at standard.Pakadali pano, masiwichi ambiri a PoE amathandizira ponse pawiri komanso pa, choncho samalani kwambiri pogula.

2. Doko lakuthupi

Choyamba, m'pofunika kudziwa chiwerengero cha malo osinthira, chiwerengero cha madoko kuwala CHIKWANGWANI, kasamalidwe maukonde, liwiro (10/100/1000M) ndi nkhani zina.Pakadali pano, zolumikizira pamsika ndizo makamaka 8, 12, 16, ndi 24 madoko.Nthawi zambiri pamakhala madoko amodzi kapena awiri owoneka bwino, ndipo muyenera kusamala ngati doko la kuwala ndi 100M kapena 1000M.Zimatengera momwe zinthu ziliri.

Ma switch a PoE nthawi zambiri amagwiritsidwa ntchito kulumikiza ma terminals ndipo amagwiritsidwa ntchito ngati zosinthira zolowera.Ganizirani kuchuluka kwa madoko amagetsi a PoE omwe amathandizidwa ndi chosinthira molingana ndi kuchuluka kwa zida zoyendetsedwa ndi magetsi.Kuphatikiza apo, m'pofunikanso kuganizira kuchuluka kwazomwe doko liyenera kuthandizira molingana ndi ma terminal omwe ali ndi mphamvu komanso zosowa zenizeni.Mwachitsanzo, ngati doko la AP ndi Gigabit ndipo limagwiritsa ntchito 11AC kapena awiri-band, mwayi wa Gigabit ukhoza kuganiziridwa.

3. Zopatsa mphamvu zamagetsi

Sankhani chosinthira choyenera molingana ndi protocol yamagetsi (monga 802.3af, 802.3at kapena PoE yosakhazikika) yothandizidwa ndi cholumikizira magetsi (AP kapena IP kamera).Protocol yamagetsi ya PoE yothandizidwa ndi chosinthira iyenera kukhala yogwirizana ndi cholumikizira magetsi.Pali zoopsa zambiri zomwe zingatheke pachitetezo pakusintha kwaposachedwa kwa PoE.Ndibwino kuti muyese kusankha zida zosinthira za 48V PoE.

4. Wiring scheme

Ogwiritsa ntchito amatha kuyerekeza ndi kuwerengera mtengo wa mawaya amagetsi am'deralo komanso mtengo wogwiritsa ntchito switch ya PoE popereka magetsi.Pakadali pano, mtunda wamagetsi wamagetsi a PoE uli mkati mwa 100 metres.Palibe zoletsa masanjidwe, zomwe zingapulumutse pafupifupi 50% ya mtengo wonse.Mawaya mkati mwa 100 metres amatha kukulitsa maukonde mosavuta popanda kuletsedwa ndi masanjidwe a zingwe zamagetsi.Yendetsani ma AP opanda zingwe, makamera a netiweki ndi zida zina zomaliza pamakoma atali kapena denga kuti mukulitse, mawaya osavuta, komanso mawonekedwe okongola.

5. Pre-sales and after-sales technical support

Sankhani amalonda odalirika kuti mupeze ntchito zogulitsiratu komanso zotsatsa pambuyo pake
