1.Mwachidule
Intaneti ya Zinthu imakonzekeretsa masensa kuzinthu zenizeni zosiyanasiyana monga ma gridi amagetsi, njanji, milatho, tunnel, misewu yayikulu, nyumba, makina operekera madzi, madamu, mapaipi amafuta ndi gasi, ndi zida zapakhomo, ndikuzilumikiza kudzera pa intaneti, kenako ndikuyendetsa. mapulogalamu enieni kuti akwaniritse kuwongolera kwakutali Kapena kukwaniritsa kulumikizana mwachindunji pakati pa zinthu.Kupyolera mu intaneti ya Zinthu, kompyuta yapakati ingagwiritsidwe ntchito kuyang'anira ndi kuyang'anira makina, zipangizo, ndi ogwira ntchito, komanso kuyang'anira kutali kwa zipangizo zapakhomo ndi magalimoto, komanso ntchito zosiyanasiyana monga kupeza malo ndi kuteteza zinthu kuti zisabedwe. .M'mapulogalamu ambiri omwe ali pamwambawa, palibe kusowa kwa teknoloji yopangira magetsi, ndipo POE (POwerOverEthernet) ndi teknoloji yomwe imatha kutumiza mphamvu ndi deta ku chipangizochi kudzera muzitsulo zopotoka mu Ethernet.Kudzera muukadaulo uwu, kuphatikiza mafoni a pa intaneti, masiteshoni opanda zingwe, makamera a netiweki, ma hubs, ma terminals anzeru, zida zamakono zamaofesi, makompyuta, ndi zina zambiri, ukadaulo wa POE ungagwiritsidwe ntchito kupereka mphamvu kuti amalize kugwira ntchito kwa zida zosiyanasiyana.Zida zamagetsi zomwe zimagwiritsidwa ntchito ndi intaneti zingagwiritsidwe ntchito popanda zowonjezera zowonjezera mphamvu, kotero panthawi imodzimodziyo zimatha kusunga nthawi ndi ndalama zokonzekera chingwe chamagetsi, kuti mtengo wa chipangizo chonsecho ukhale wochepa.Ndi kufalikira kwa Efaneti, ma socket a RJ-45 network amagwiritsidwa ntchito kwambiri padziko lapansi, kotero mitundu yonse ya zida za POE zimagwirizana.POE sichifunikira kusintha mawonekedwe a chingwe cha dera la Efaneti kuti agwire ntchito, kotero kugwiritsa ntchito dongosolo la POE sikungopulumutsa ndalama, ndikosavuta kuyimba ndi kukhazikitsa, komanso kutha kuyimitsa ndikuyimitsa kutali.
2.Kugwiritsa ntchito kwakukulu kwa POE pa intaneti ya Zinthu
Ndi chitukuko chaukadaulo ndi kugwiritsa ntchito, kulumikizana kwa intaneti ya Zinthu kukukulirakulirabe, ndipo kumvetsetsa kwatsopano kwatulukira-Intaneti ya Zinthu ndikugwiritsa ntchito kukulitsa ndi kukulitsa maukonde a netiweki yolumikizirana ndi intaneti.Imagwiritsa ntchito ukadaulo wa kuzindikira ndi zida zanzeru kuzindikira ndikuzindikira dziko lapansi.Kutumiza kwa ma netiweki ndi kulumikizana, kuwerengera, kukonza ndi migodi ya chidziwitso, kuzindikira kulumikizana kwa chidziwitso ndi kulumikizana kosasunthika pakati pa anthu ndi zinthu, ndi zinthu ndi zinthu, ndikukwaniritsa cholinga chowongolera nthawi yeniyeni, kasamalidwe kolondola komanso kupanga zisankho zasayansi pazachilengedwe. .Chifukwa chake, maukonde sangakwaniritse zosowa za ogwiritsa ntchito, koma aziwona kusintha kwazomwe akugwiritsa ntchito, kuyanjana ndi zidziwitso, ndikupatsa ogwiritsa ntchito ntchito zawo.
Zotsatira zaukadaulo wamaneti opanda zingwe pa anthu ndizosatsutsika.Mitundu yogwiritsira ntchito maukonde amdera lanu opanda zingwe ikukula ndikukulirakulira, m'maofesi akulu, malo osungiramo zinthu zanzeru, mayunivesite, malo ogulitsira, ma eyapoti, malo ochitira misonkhano ndi ziwonetsero, mahotela, ma eyapoti, zipatala, ndi zina zambiri. zofuna za anthu kuti azifufuza pa intaneti nthawi iliyonse, kulikonse.Pogwiritsa ntchito ma netiweki opanda zingwe, ntchito yofunika kwambiri ndiyo kukhazikitsa koyenera komanso kothandiza kwa AP opanda zingwe (AccessPOint).Pulatifomu yamtambo ya TG imatha kupereka kasamalidwe kokwanira pakati, moyenera komanso moyenera.M'mapulojekiti akuluakulu owonetsera opanda zingwe, pali ma AP ambiri opanda zingwe ndipo amagawidwa m'madera osiyanasiyana a nyumbayi.Nthawi zambiri, ma AP amafunikira zingwe zama netiweki kuti alumikizane ndi ma switch ndi maulumikizidwe akunja.DC magetsi.Kuthetsa mphamvu ndi kasamalidwe pomwepo kudzakulitsa kwambiri mtengo wa zomangamanga ndi kukonza.Kusintha kwamagetsi a "UNIP" kumathetsa vuto lamagetsi apakati a ma AP opanda zingwe kudzera pa network cable power supply (POE), yomwe imatha kuthetsa mavuto amagetsi am'deralo omwe amakumana nawo pakumanga projekiti komanso mavuto amtsogolo a AP.Izi zimalepheretsa ma AP pawokha kulephera kugwira ntchito moyenera panthawi yozimitsa pang'ono magetsi.Mu yankho ili, ndikofunikira kugwiritsa ntchito zida za AP zomwe zimathandizira 802.3af/802.3af protocol ntchito kuti mukwaniritse ntchito yamagetsi amagetsi.Ngati AP sichigwirizana ndi ntchito ya protocol ya 802.3af/802.3af, mutha kukhazikitsa mwachindunji deta ndi POE synthesizer kuti mumalize ntchitoyi.Monga momwe chithunzi 1:
3. Kugwiritsa ntchito ma terminal anzeru a POE pa intaneti ya Zinthu
Poyimba foni kunyumba, ngati pali kulephera kwadzidzidzi kwamphamvu, kuyimbako sikungasokonezedwe.Izi zili choncho chifukwa magetsi a telefoni amaperekedwa mwachindunji ndi kampani ya matelefoni (ofesi yapakati) yodutsa mu mzere wa telefoni.Tangoganizani kuti ngati masensa am'munda wa mafakitale, owongolera ndi ma terminal anzeru pa intaneti ya Zinthu amathanso kuyendetsedwa mwachindunji ndi Ethernet pazida zamakono zamaofesi, ndiye kuti mawaya onse, magetsi, ntchito ndi ndalama zina zitha kuchepetsedwa kwambiri, ndi Kukulitsa. kuyang'anira kuzinthu zambiri zakutali, awa ndi masomphenya owonetsedwa ndi luso la POE ku gulu lolamulira mafakitale la intaneti ya Zinthu.Mu 2003 ndi 2009, IEEE idavomereza miyezo ya 802.3af ndi 802.3at motsatana, yomwe imafotokoza momveka bwino za kuzindikira ndi kuwongolera mphamvu pamayendedwe akutali, ndikugwiritsa ntchito zingwe za Efaneti kwa ma rauta, masiwichi, ndi ma hubs kuti azilumikizana ndi mafoni a IP, machitidwe otetezera. , ndi opanda zingwe Njira yoperekera magetsi pazida monga malo ofikira pa LAN imayendetsedwa.Kutulutsidwa kwa IEEE802.3af ndi IEEE802.3at kwalimbikitsa kwambiri chitukuko ndi kugwiritsa ntchito luso la POE.
