1.Overview
IInternet yezvinhu inoshongedzera masensa kune akasiyana chaiwo zvinhu zvakaita semagetsi grid, njanji, mabhiriji, tunnel, migwagwa mikuru, zvivakwa, masisitimu ekupa mvura, madhamu, pombi dzemafuta negasi, uye midziyo yemumba, uye inozvibatanidza kuburikidza neInternet, uye wobva wamhanya. mapurogiramu chaiwo ekuwana kure kure kana kuwana kutaurirana kwakananga pakati pezvinhu.Kuburikidza neInternet yezvinhu, komputa yepakati inogona kushandiswa kubata nekudzora michina, midziyo, nevashandi, pamwe nekudzora kure kwemidziyo yemumba nemotokari, pamwe nekushandisa kwakasiyana sekutsvaga nzvimbo uye kudzivirira zvinhu kuti zvibiwa. .Muzvizhinji zvezvishandiso zviri pamusoro apa, hapana kushaikwa kwehunyanzvi hwekugovera magetsi, uye POE (POwerOverEthernet) inyanzvi inokwanisa kuendesa simba uye data kune mudziyo kuburikidza neakamonyoroka peya muEthernet.Kuburikidza nehunyanzvi uhu, hunosanganisira nharembozha dzeInternet, zviteshi zvisina waya, network makamera, hubs, smart terminals, zvemazuva ano smart office michina, makomputa, nezvimwe, tekinoroji yePOE inogona kushandiswa kugovera magetsi kupedzisa kushanda kwemidziyo yakasiyana.Midziyo yemagetsi inoshandiswa netiweki inogona kushandiswa pasina mamwe masokisi emagetsi, saka panguva imwechete inogona kuchengetedza nguva nemari yekugadzira tambo yemagetsi, kuitira kuti mari yehurongwa hwese hugadziriswe hushoma.Nekushandiswa kwakapararira kweEthernet, RJ-45 network sockets inoshandiswa zvakanyanya munyika, saka marudzi ese emidziyo yePOE inowirirana.POE haidi kushandura tambo yetambo yeEthernet wedunhu kuti ishande, saka kushandiswa kwePOE system haingochengetedze mari chete, iri nyore kuisa waya nekuisa, asiwo inokwanisa kudzima nekudzima kure.
2.Kushandiswa kukuru kwePOE muInternet yezvinhu
Nekuvandudzwa kwetekinoroji uye mashandisirwo, chirevo cheInternet yezvinhu chiri kuramba chichiwedzera, uye manzwisisiro matsva abuda-Indaneti Yezvinhu ndiyo yekuwedzera application uye netiweki yekuwedzera yetiweki yekutaurirana neInternet.Inoshandisa tekinoroji yekuona uye zvishandiso zvakangwara kuona uye kuziva nyika yenyama.Network kutapurirana nekubatanidza, kuverenga, kugadzirisa uye kuziva migodhi, ziva kupindirana kweruzivo nekubatana kusina musono pakati pevanhu nezvinhu, nezvinhu nezvinhu, uye kuzadzisa chinangwa chekutonga-chaiyo-nguva, kutonga kwakaringana uye kuita sarudzo yesainzi yenyika. .Naizvozvo, iyo network haichazozadzisa zvidikanwi zvevashandisi, asi ichanyatso kuona shanduko mumamiriro evashandisi, kuita kudyidzana kweruzivo, uye kupa vashandisi masevhisi emunhu.
Kukanganisa kwetekinoroji isina waya kune vanhu hakupokane.Kuwanda kwemashandisirwo enzvimbo isina waya yenzvimbo network iri kuramba ichiwedzera nekufara, mumahofisi makuru, matura akangwara, makampasi emayunivhesiti, mashopu, nhandare dzendege, nzvimbo dzemagungano nenzvimbo dzekuratidzira, mahotera, nhandare dzendege, zvipatara, etc. Mabhawa, zvitoro zvekofi, nezvimwe. zvinodiwa nevanhu kuti vavhure Indaneti chero nguva, chero kupi.Muchiito chekuendesa network isina waya, iro rakakosha basa nderekumisikidza uye kunoshanda kweiyo isina waya AP (AccessPOint).Iyo TG yegore chikuva inogona kupa yakakwana seti yekutonga mune yepakati, inonzwisisika uye inoshanda maitiro.Mumapurojekiti makuru ekuvhara netiweki isina waya, kune huwandu hukuru hwemawire AP uye akagoverwa munzvimbo dzakasiyana dzechivako.Kazhinji, ma AP anoda tambo dzetiweki kuti abatanidze kune switch uye ekunze kubatana.DC simba rekupa.Kugadzirisa simba uye manejimendi panzvimbo yacho kuchawedzera zvakanyanya mutengo wekuvaka nekugadzirisa.Iyo "UNIP" magetsi emagetsi switch inogadzirisa dambudziko repakati pemagetsi emagetsi asina waya APs kuburikidza netiweki tambo magetsi emagetsi (POE), ayo anogona kugadzirisa zvakanyanya matambudziko emagetsi emunharaunda akasangana panguva yekuvaka chirongwa uye mune ramangwana AP manejimendi matambudziko.Izvi zvinodzivirira maAP ega ega kuti atadze kushanda zvakanaka panguva yekudzima kwemagetsi.Mumhinduro iyi, zvinodikanwa kushandisa AP michina inotsigira 802.3af/802.3af protocol mabasa kuti uwane basa re network tambo magetsi.Kana iyo AP isingatsigire iyo 802.3af/802.3af protocol basa, unogona kuisa zvakananga data uye POE synthesizer kuti upedze iyi magetsi ekupa basa.Sezvinoratidzwa Mufananidzo 1:
3. Kushandiswa kwePOE smart terminals muInternet yezvinhu
Paunenge uchifona kumba, kana pane kamwe kamwe kutadza simba, kufona hakuzovhiringidzwa.Izvi zvinodaro nekuti magetsi echiteshi chenhare anopihwa zvakananga nekambani yenhare (central office) switch kuburikidza netambo yefoni.Fungidzira kuti kana maindasitiri emunda ma sensors, controllers uye smart terminal actuators muInternet yeZvinhu anogona zvakare kufambiswa zvakananga neEthernet yemidziyo yemazuva ano yehofisi, ipapo wiring yese, magetsi, vashandi uye zvimwe zvinodhura zvinogona kudzikiswa zvakanyanya, uye Kuwedzera. kutarisa kune akawanda maapplication ari kure, ichi chiono chinoratidzwa nePOE tekinoroji kunharaunda inodzora maindasitiri yeInternet yezvinhu.Muna 2003 na2009, IEEE yakabvumira 802.3af uye 802.3at zviyero zvakateerana, izvo zvinonyatso tsanangura magetsi ekuona uye kutonga zvinhu zviri kure, uye yakashandisa Ethernet tambo dze routers, switch, uye hubs kutaurirana neIP mafoni, kuchengetedza masisitimu. , uye isina waya Iyo nzira yekupa magetsi yemidziyo yakadai seLAN yekuwana nzvimbo inodzorwa.Kuburitswa kweIEEE802.3af neIEEE802.3at kwakakurudzira zvikuru kusimukira uye kushandiswa kwehunyanzvi hwePOE.
