Hamwe niterambere ryubukungu niterambere ryimibereho, abantu baterana byinshi kumugaragaro.Muri icyo gihe, kwangiza imanza z'umutekano rusange nabyo bizana ibibazo bikomeye muri societe ibanye.Sisitemu ya Kamera na Surveillance irashobora gutanga igihe nyacyo cyo gukurikirana amashusho no gufata amashusho, bigatanga urufatiro rukomeye rwo gukusanya ibimenyetso nyuma yiterambere. Iterambere ryihuse rya Kamera na Surveillance ritanga uburyo bwiza bwo kubaka "umujyi uhuza" .Data yakusanyirijwe hamwe ingingo zo gukusanya amashusho zatanzwe muri Kamera na sisitemu yo kugenzura bigomba koherezwa kuri seriveri mugihe nyacyo cyo kureba, gusesengura no kuvuga muri make. Umuyoboro wogukwirakwiza amakuru ni ingingo igoye mu iyubakwa rya sisitemu yo gukurikirana imijyi no gutabaza, hamwe n'uruhare rukomeye rwa gahunda yo kohereza amakuru iragenda igaragara cyane.EPON, ishobora gutanga umurongo mugari, yahindutse ikoranabuhanga ryingenzi imikoreshereze nini yubucuruzi ishingiye.
Hamwe niterambere ryikoranabuhanga ryitumanaho, tekinoroji ya EPON yagiye yinjizwa buhoro buhoro murwego rwo gukurikirana umutekano.Numuyoboro mugari wa tekinoroji ya point-to-kugwiza imiterere y'urusobekerane hamwe na optique ya fibre optique.
Kugeza ubu, ibyiza bya tekinoroji ya EPON bigaragarira buhoro buhoro, cyane cyane muri Kamera no kugenzura.Iyo EPON ikoreshwa muburyo bwo gukurikirana imiyoboro, irashobora gutanga umukino wuzuye kubyiza byumuvuduko mwinshi mugihe gikemura amakuru yibanze ya videwo ku giciro gito, kandi ibintu byoroshye kandi byoroshye birashobora kugabanya cyane igiciro rusange no kubungabunga ibiciro byurusobe. .
Umuyoboro wa EPON ufite ibyiza bikurikira:
1.Kwizerwa cyane.EPON ni fibre itandukanya na fibre optique.Ifite ubuzima burebure kandi nta bikoresho bikora.Irinda kunanirwa kw'amashanyarazi, gukubita inkuba, kwangirika kwinshi na volvoltage, n'ibindi. Umuyoboro ufite kwizerwa cyane kandi ugabanya amafaranga yo kubungabunga.
2.kiguzi.Tekinoroji ya EPON yo gukwirakwiza fibre imwe, ikiza kimwe cya kabiri cya fibre kuruta kwanduza fibre isanzwe.Byongeye kandi, EPON ntisaba amashanyarazi yo hanze mugihe cyo kohereza, biroroshye kuyashyiraho, kandi mubyukuri ntibisaba kubungabungwa, bishobora kuzigama amafaranga yo gukora nibiciro byo kuyobora.
3.Umurongo mwinshi.1Gmps igipimo cyogukwirakwiza, gishobora kuzuza byoroshye ibisabwa na serivisi zishinzwe kugenzura amashusho.Umuyoboro mugari wa buri ONU urashobora guhindurwa muburyo hagati ya 2M na 1Gmps.Impuzandengo yo hejuru yubugari bwicyambu cya OLT muri buri ONU ni 30M, yujuje byuzuye ibisabwa na IPTV.
4.EPON ifite imikorere ihanitse kandi umuvuduko wa EPON urashobora kugera kumurongo umwe muremure wo hejuru no kumanuka wa 1.25Gb / s.Umuvuduko ntarengwa urashobora kugera kuri 10Gb / s, intera ntarengwa ishobora kugera kuri 20km, ikwiranye cyane nu gukwirakwiza urusobe rwumujyi wa metropolitani, kandi ahanini bikubiyemo intera yubuso buciriritse.
5.Urusobe rworoshye, kandi igipimo cyo hejuru cyo gutandukanya optique ni 1:64.Urusobekerane rwibiti byubatswe byemewe kugirango bibe ingingo-kuri-kugwiza abakoresha urusobe topologiya binyuze mu guhuza ibice bitandukanye bya optique.Binyuze mu igenamigambi ryumvikana no gushushanya, ibikoresho bya fibre birashobora kubikwa cyane.Ni igisubizo cyiza kubibazo byo gukusanya amashusho no gutatanya.
Ihame ry'ikoranabuhanga rya EPON
EPON Network Umuyoboro wa Ethernet Passive Optical Network network Umuyoboro wa Ethernet passique optique ni umusaruro woguhuza neza kwikoranabuhanga rya Ethernet nubuhanga bwa PON.
Kugirango utandukanye ibimenyetso muburyo bwo kohereza no kwakira abayikoresha benshi kuri fibre imwe, tekinoroji ebyiri zikurikira zikoreshwa: uburyo bwo kumanura amakuru bukoresha ikoranabuhanga ryamamaza, naho amakuru ya uplink akoresha tekinoroji ya TDMA.
Porogaramu ya EPON muri Kamera no kugenzura
Ikoranabuhanga rya EPON rirangwa numuyoboro mwinshi, gutuza cyane no gukoresha cyane umutungo wumurongo.Iri koranabuhanga rifite ibyiza karemano byo gukurikirana ikigo.Bwa mbere, kugenzura ikigo bisaba umuvuduko wihuse, wujuje ubuziranenge bwibidukikije byigenga kugirango bitware serivise nziza za videwo.Ikoranabuhanga rya EPON ritanga umurongo wa 1Gbps wihuta, ushobora kuzuza byuzuye ibikenerwa na serivisi za videwo. Icya kabiri, imiterere ya topologiya ya EPON yoroheje yita cyane kumiterere yatatanye ya parike. Yaba ari itsinda ryinshi ryinyubako cyangwa umuhanda muto, irashobora gushyirwaho numuyoboro ukwiye. Ubwanyuma, umutekano muke numutekano muke ya EPON nayo izamura urwego rwikoranabuhanga rwo kugenzura parike kurwego rushya.
Iyo ingingo zikurikiranwa cyane zikenewe hagati ya parike, EPON irashobora gukoresha imiyoboro isanzwe.Icyambu kimwe cya PON cyibikoresho bya OLT gihujwe na 1: N spectrometer.Nyuma yo kugera imbere-optique ya optique, ibikoresho byinshi bya ONU birahujwe. Koresha inyungu zose z'uburebure bwogukwirakwiza fibre optique, bigera no kubikenewe byose byoherezwa muri kariya gace. Fibre yibikoresho irashobora kubikwa kugirango igere nyuma yo kwaguka.
Igenzura ryimihanda ikikije irashobora gukorwa muburyo bwo guhuza ibice byo kugenzura imihanda ikurikiranye. Mubidukikije bito byo mukarere, EPON ifite uburebure bwa 20KM irashobora gutanga uburyo.Mu gace kanini, inzira nyinshi zirashobora gukoreshwa mugukemura ikibazo cyintera.
