1.Amagqabantshintshi
I-Intanethi yeZinto ixhobisa abenzi boluvo kwizinto ezahlukeneyo zokwenyani ezinje ngeegridi zamandla, oololiwe, iibhulorho, iitonela, iindlela ezinkulu, izakhiwo, iinkqubo zokubonelela ngamanzi, amadama, imibhobho ye-oyile negesi, kunye nezixhobo zendlu, kwaye ziqhagamshele kwi-Intanethi, emva koko ziqhube. iinkqubo ezithile ukufezekisa ulawulo olukude Okanye ukuphumeza unxibelelwano oluthe ngqo phakathi kwezinto.Nge-Intanethi yezinto, ikhompyuter ephakathi ingasetyenziselwa ukulawula nokulawula oomatshini, izixhobo, kunye nabasebenzi, kunye nolawulo olukude lwezixhobo zasekhaya kunye neemoto, kunye nezicelo ezahlukeneyo ezinjengokufumana indawo kunye nokuthintela izinto ekubiweni. .Kwizicelo ezininzi ezingentla, akukho kungabikho kobuchwephesha bokubonelela ngombane, kwaye i-POE (i-POwerOverEthernet) iteknoloji enokudlulisa amandla kunye nedatha kwisixhobo ngokusebenzisa ibini elijijekileyo kwi-Ethernet.Ngobu buchwepheshe, kubandakanywa iifowuni ze-Intanethi, izikhululo ze-wireless, iikhamera zenethiwekhi, ii-hubs, iitheminali ezihlakaniphile, izixhobo ze-ofisi ze-smart zala maxesha, iikhompyutha, njl. njl., iteknoloji ye-POE ingasetyenziselwa ukubonelela ngombane ukugqiba ukusebenza kwezixhobo ezahlukeneyo.Izixhobo zombane ezixhaswe ngumnatha zingasetyenziselwa ngaphandle kweesokethi zamandla ezongezelelweyo, ngoko ke ngexesha elifanayo linokugcina ixesha kunye nemali yokuqwalasela intambo yamandla, ukwenzela ukuba iindleko zenkqubo yonke yesixhobo ziyancipha.Ngokusetyenziswa ngokubanzi kwe-Ethernet, i-RJ-45 iziseko zenethiwekhi zisetyenziswa ngokubanzi kwihlabathi, ngoko ke zonke iintlobo zezixhobo ze-POE ziyahambelana.I-POE ayifuni ukutshintsha i-cable structure ye-Ethernet yesekethe ukuze isebenze, ngoko ke ukusetyenziswa kwenkqubo ye-POE ayigcini nje kuphela iindleko, kulula ukuyifaka ucingo kunye nokuyifaka, kodwa inamandla ombane kunye nokucima ukude.
2.Usetyenziso oluphambili lwe-POE kwi-Intanethi yeZinto
Ngophuhliso lwetekhnoloji kunye nokusetyenziswa, ukudityaniswa kwe-Intanethi ye-Intanethi ye-Intanethi kuyaqhubeka ukwanda, kwaye ukuqonda okutsha kuye kwavela-i-Intanethi yeZinto sisicelo sokwandiswa kunye nokwandiswa kwenethiwekhi yenethiwekhi yonxibelelwano kunye ne-Intanethi.Isebenzisa itekhnoloji yokubona kunye nezixhobo ezikrelekrele ukubona nokuqonda umhlaba obonakalayo.Ukuhanjiswa kwenethiwekhi kunye nokunxibelelana, ukubala, ukusetyenzwa kunye nolwazi lwemigodi, ukuqonda intsebenziswano yolwazi kunye nonxibelelwano olungenamthungo phakathi kwabantu nezinto, nezinto kunye nezinto, kwaye ufezekise injongo yolawulo lwexesha lokwenyani, ulawulo oluchanekileyo kunye nokwenziwa kwezigqibo zenzululwazi zehlabathi elibonakalayo. .Ke ngoko, inethiwekhi ayisayi kuphinda ihlangabezane neemfuno zabasebenzisi, kodwa iya kubona utshintsho kwiimeko zabasebenzisi, iqhube unxibelelwano lolwazi, kwaye ibonelele abasebenzisi ngeenkonzo zobuqu.
Impembelelo yeteknoloji yenethiwekhi engenazingcingo ebantwini ayinakuphikiswa.Uluhlu lwesicelo sothungelwano lwengingqi olungenazintambo luba lubanzi kwaye lubanzi, kwiiofisi ezinkulu, iindawo zokugcina izinto ezihlakaniphile, iikhampasi zeyunivesithi, iindawo zokuthenga, izikhululo zeenqwelo moya, amaziko endibano kunye nemiboniso, iihotele, izikhululo zeenqwelo moya, izibhedlele, njl. Iibha, iivenkile zekofu, njl. iimfuno zabantu zokujonga i-Intanethi nanini na, naphi na.Kwinkqubo yokuthumela inethiwekhi engenazintambo, owona msebenzi ubaluleke kakhulu kukufakela okufanelekileyo kunye nokusebenzayo kwe-wireless AP (AccessPOint).Iqonga lelifu le-TG linokubonelela ngeseti epheleleyo yolawulo kwindawo esembindini, enengqiqo nesebenzayo.Kwiiprojekthi ezinkulu zokugubungela inethiwekhi engenazingcingo, kukho inani elikhulu lee-APs ezingenazingcingo kwaye zisasazwa kwiindawo ezahlukeneyo zesakhiwo.Ngokuqhelekileyo, ii-APs zidinga iintambo zenethiwekhi ukuxhuma kwiitshintshi kunye nokudibanisa kwangaphandle.DC unikezelo lwamandla.Ukusombulula amandla kunye nolawulo kwindawo kuya kwandisa kakhulu iindleko zokwakha kunye nokugcinwa.Umbane wombane othi "UNIP" usombulula ingxaki yonikezelo lwamandla oluphakathi kwi-wireless APs ngokusebenzisa umbane wentambo yenethiwekhi (POE), enokusombulula kakhulu iingxaki zonikezelo lwamandla asekuhlaleni adibana nawo ngexesha lokwakhiwa kweprojekthi kunye neengxaki zolawulo lwe-AP kwixesha elizayo.Oku kuthintela i-APs nganye ekusileleni ukusebenza kakuhle ngexesha lokumka kombane.Kwesi sisombululo, kuyimfuneko ukusebenzisa izixhobo ze-AP ezixhasa imisebenzi yeprotocol ye-802.3af/802.3af ukufezekisa umsebenzi wokunikezelwa kombane wentambo yenethiwekhi.Ukuba i-AP ayixhasi umsebenzi weprotocol we-802.3af/802.3af, ungafaka ngokuthe ngqo idatha kunye ne-POE synthesizer ukugqiba lo msebenzi wokunikezelwa kwamandla.Njengoko kubonisiwe kuMfanekiso 1:
3. Ukusetyenziswa kweetheminali ze-POE ezihlakaniphile kwi-Intanethi yeZinto
Xa ufowuna ekhaya, ukuba kukho ukungaphumeleli kombane ngokukhawuleza, ifowuni ayiyi kuphazamiseka.Oku kungenxa yokuba umbane wetheminali yefowuni unikezelwa ngokuthe ngqo yinkampani yefowuni (i-ofisi ephakathi) itshintshela kwintambo yefowuni.Khawucinge ukuba ukuba i-industrial sensors, abalawuli kunye ne-smart terminal actuators kwi-Intanethi yeZinto zinokuxhaswa ngokuthe ngqo yi-Ethernet kwizixhobo zeofisi zanamhlanje, ngoko ke i-wiring yonke, ukunikezelwa kwamandla, abasebenzi kunye nezinye iindleko zingancitshiswa kakhulu, kunye nokwandisa. ukubeka iliso kwizicelo ezininzi ezikude, lo ngumbono oboniswe yiteknoloji ye-POE kuluntu lolawulo lwemizi-mveliso ye-Intanethi yeZinto.Kwi-2003 kunye ne-2009, i-IEEE yavuma imigangatho ye-802.3af kunye ne-802.3at ngokulandelanayo, echaza ngokucacileyo ukufunyanwa kwamandla kunye nokulawula izinto kwindlela ekude, kwaye isebenzise iintambo ze-Ethernet kwii-routers, switch, kunye ne-hubs ukunxibelelana neefowuni ze-IP, iinkqubo zokhuseleko. , kunye ne-wireless Indlela yonikezelo lwamandla kwizixhobo ezifana neendawo zokufikelela kwi-LAN zilawulwa.Ukukhutshwa kwe-IEEE802.3af kunye ne-IEEE802.3at kukhuthaze kakhulu uphuhliso kunye nokusetyenziswa kobuchwepheshe be-POE.
