1.Ukubuka konke
I-inthanethi Yezinto ihlomisa izinzwa ezintweni zangempela ezihlukahlukene ezifana namagridi kagesi, imizila yezitimela, amabhuloho, imigudu, imigwaqo emikhulu, izakhiwo, amasistimu okuphakelwa kwamanzi, amadamu, amapayipi kawoyela negesi, nezinto zikagesi zasendlini, futhi zizixhume nge-inthanethi, bese zisebenza. izinhlelo ezithile zokufinyelela isilawuli kude Noma ukuzuza ukuxhumana okuqondile phakathi kwezinto.Nge-inthanethi Yezinto, ikhompuyutha emaphakathi ingasetshenziselwa ukuphatha nokulawula imishini, okokusebenza, kanye nabasebenzi, kanye nokulawula okukude kwemishini yasendlini nezimoto, kanye nezinhlelo zokusebenza ezahlukahlukene ezifana nokuthola izindawo nokuvimbela izinto ukuthi zebiwe. .Eziningi zalezi zinhlelo zokusebenza ezingenhla, akukho ukushoda kobuchwepheshe bokuhlinzeka ngogesi, futhi i-POE (POwerOverEthernet) ubuchwepheshe obungadlulisela amandla nedatha kudivayisi ngepheya elisontekile ku-Ethernet.Ngalobu buchwepheshe, okuhlanganisa amafoni e-inthanethi, iziteshi ezingenantambo, amakhamera enethiwekhi, amahabhu, amatheminali ahlakaniphile, imishini yesimanje yamahhovisi ehlakaniphile, amakhompyutha, njll., ubuchwepheshe be-POE bungasetshenziswa ukuhlinzeka amandla okuqedela ukusebenza kwemishini ehlukahlukene.Imishini ye-elekthronikhi enikwe amandla yinethiwekhi ingasetshenziswa ngaphandle kwamasokhethi kagesi engeziwe, ngakho-ke ngesikhathi esifanayo ingasindisa isikhathi nemali yokulungisa intambo yamandla, ukuze izindleko zalo lonke uhlelo lwedivayisi zincishiswe.Ngokusetshenziswa kabanzi kwe-Ethernet, amasokhethi enethiwekhi ye-RJ-45 asetshenziswa kabanzi emhlabeni, ngakho-ke zonke izinhlobo zamadivayisi we-POE ziyahambisana.I-POE ayidingi ukushintsha isakhiwo sekhebula sesekethe ye-Ethernet ukuze isebenze, ngakho-ke ukusetshenziswa kwesistimu ye-POE akugcini nje ukusindisa izindleko, kulula ukuxhuma izintambo nokufaka, kodwa futhi inamandla okuvula nokuvala ukude.
2.Ukusetshenziswa okuyinhloko kwe-POE ku-inthanethi Yezinto
Ngokuthuthukiswa kobuchwepheshe nezinhlelo zokusebenza, incazelo ye-inthanethi Yezinto iyaqhubeka nokukhula, futhi ukuqonda okusha sekuvele-I-inthanethi Yezinto iwuhlelo lokusebenza lokunwetshwa kanye nokwelulwa kwenethiwekhi yenethiwekhi yokuxhumana ne-inthanethi.Isebenzisa ubuchwepheshe bokubona kanye namadivayisi ahlakaniphile ukuze abone futhi abone umhlaba obonakalayo.Ukudluliswa kwenethiwekhi nokuxhumana, ukubala, ukucubungula kanye nezimayini zolwazi, qaphela ukuxhumana kolwazi nokuxhumana okungenazihibe phakathi kwabantu nezinto, nezinto nezinto, futhi kufezwe injongo yokulawula kwesikhathi sangempela, ukuphatha okunembayo kanye nokwenziwa kwezinqumo zesayensi zomhlaba obonakalayo. .Ngakho-ke, inethiwekhi ngeke isahlangabezana nezidingo zabasebenzisi ngokunganaki, kodwa izobona izinguquko ezimweni zabasebenzisi, iqhube ukusebenzelana kolwazi, futhi inikeze abasebenzisi ngamasevisi aqondene nawe.
Umthelela wobuchwepheshe benethiwekhi engenantambo kubantu awunakuphikiswa.Uhla lokusetshenziswa kwenethiwekhi yendawo engenantambo luya luba banzi futhi luba banzi, emahhovisi amakhulu, ezindlini zokugcina izimpahla ezihlakaniphile, amakhampasi amanyuvesi, izitolo ezinkulu, izikhumulo zezindiza, izikhungo zemihlangano nemibukiso, amahhotela, izikhumulo zezindiza, izibhedlela, njll. Amabha, izitolo zekhofi, njll. ziyaqaphela. izidingo zabantu zokungena ku-inthanethi nganoma yisiphi isikhathi, noma kuphi.Enqubweni yokukhipha inethiwekhi engenantambo, umsebenzi obaluleke kakhulu ukufakwa okunengqondo nokusebenzayo kwe-AP engenantambo (AccessPOint).Inkundla yefu ye-TG inganikeza isethi ephelele yokuphatha ngendlela emaphakathi, enengqondo nephumelelayo.Kumaphrojekthi amakhulu wokuhlanganisa inethiwekhi engenantambo, kunenombolo enkulu yama-AP angenawaya futhi asatshalaliswa ezingxenyeni ezihlukahlukene zesakhiwo.Ngokuvamile, ama-AP adinga izintambo zenethiwekhi ukuze axhume ekushintsheni nasekuxhumekeni kwangaphandle.Ukunikezwa kwamandla kwe-DC.Ukuxazulula amandla nokuphatha khona lapho kuzokhuphula kakhulu izindleko zokwakha nokunakekela.Iswishi kagesi ye-"UNIP" ixazulula inkinga yokuphakelwa kwamandla okumaphakathi kwama-APs angenawaya ngokusebenzisa intambo kagesi yenethiwekhi (POE), engaxazulula kakhulu izinkinga zokuphakelwa kukagesi wendawo okuhlangatshezwane nazo ngesikhathi sokwakhiwa kwephrojekthi kanye nezinkinga zesikhathi esizayo zokuphatha i-AP.Lokhu kuvimbela ama-AP angawodwana ekuhlulekeni ukusebenza kahle phakathi nokucisha kukagesi ingxenye.Kulesi sixazululo, kuyadingeka ukusebenzisa okokusebenza kwe-AP okusekela imisebenzi yephrothokholi engu-802.3af/802.3af ukuze kufezwe umsebenzi wokuphakelwa kwamandla kwentambo yenethiwekhi.Uma i-AP ingawusekeli umsebenzi wephrothokholi we-802.3af/802.3af, ungakwazi ukufaka ngokuqondile idatha ne-POE synthesizer ukuze uqedele lo msebenzi wokunikezela amandla.Njengoba kuboniswe kuMfanekiso 1:
3. Ukusetshenziswa kwamatheminali ahlakaniphile e-POE ku-inthanethi Yezinto
Uma ushaya ucingo ekhaya, uma kwenzeka ugesi uphela kungazelelwe, ucingo ngeke luphazamiseke.Lokhu kungenxa yokuthi ugesi wetheminali yocingo uhlinzekwa ngokuqondile yinkampani yocingo (ihhovisi eliphakathi) eshintsha ngocingo.Cabanga ukuthi uma izinzwa zenkundla yezimboni, izilawuli kanye nama-smart terminal actuators ku-inthanethi Yezinto zingaphinda zinikwe amandla ngokuqondile yi-Ethernet yemishini yesimanje yasehhovisi, khona-ke zonke izintambo, ukunikezwa kwamandla, abasebenzi kanye nezinye izindleko zingancishiswa kakhulu, kanye Nokwelula. ukuqapha izinhlelo zokusebenza eziningi ezikude, lona umbono ovezwa ubuchwepheshe be-POE emphakathini wokulawula izimboni we-inthanethi Yezinto.Ngo-2003 no-2009, i-IEEE yagunyaza izindinganiso ze-802.3af kanye ne-802.3at ngokulandelanayo, ezibeka ngokucacile ukutholwa nokulawula izinto kusistimu ekude, futhi yasebenzisa izintambo ze-Ethernet zamarutha, amaswishi, namahabhu ukuxhumana namafoni we-IP, izinhlelo zokuphepha. , kanye ne-wireless Indlela yokunikezela amandla yamadivayisi afana nezindawo zokufinyelela ze-LAN ilawulwa.Ukukhishwa kwe-IEEE802.3af ne-IEEE802.3at kukhuthaze kakhulu ukuthuthukiswa nokusebenzisa ubuchwepheshe be-POE.
