Mugihe societe igezweho itera imbere, imiyoboro yabaye igice cyingenzi mubuzima bwa buri munsi, kandi itumanaho ryerekana ibimenyetso rishingiye kumurongo wurusobe (bakunze kwita insinga za Ethernet). Nka nganda igezweho yinganda zinyanja, inyanja ninyanja ziragenda zikora kandi zifite ubwenge. Ibidukikije biraruhije, bishyira hejuru kurwego rwimigozi ya Ethernet nibikoresho byakoreshejwe. Uyu munsi, turaza kumenyekanisha muri make ibiranga imiterere, uburyo bwo gutondekanya ibintu, hamwe nibikoresho byingenzi bigizwe ninsinga za marine Ethernet.
1.Ishyirwa mu byiciro
(1) .Kurikije imikorere yo kohereza
Umugozi wa Ethernet dukunze gukoresha mubusanzwe ukorwa hamwe nuyobora umuringa uhindagurika wubatswe, urimo imiyoboro y'umuringa imwe cyangwa myinshi, ibikoresho bya insulasiyo ya PE cyangwa PO, byahinduwe kubiri, hanyuma ibice bine bigizwe numuyoboro wuzuye. Ukurikije imikorere, amanota atandukanye yinsinga arashobora guhitamo:
Icyiciro 5E (CAT5E): Urupapuro rwo hanze rusanzwe rukozwe muri PVC cyangwa umwotsi muke wa halogene utarimo polyolefin, hamwe numuyoboro wa 100MHz kandi umuvuduko ntarengwa wa 1000Mbps. Ikoreshwa cyane murugo no mubiro rusange byibiro.
Icyiciro cya 6 (CAT6): Koresha imiyoboro yo mu rwego rwo hejuru kandipolyethylene yuzuye (HDPE)ibikoresho byo kubika, hamwe nuburyo butandukanye, byongera umurongo wa 250MHz kugirango bikwirakwizwa neza.
Icyiciro cya 6A (CAT6A): Umuvuduko wiyongera kugeza kuri 500MHz, umuvuduko wogukwirakwiza ugera kuri 10Gbps, mubisanzwe ukoresha kaseti ya aluminiyumu ya Mylar nkibikoresho bikingira ikibirindiro, kandi igahuzwa hamwe nubushobozi buke bwumwotsi muke wa halogene utagira ibyatsi kugirango ukoreshwe mubigo byamakuru.
Icyiciro 7 / 7A (CAT7 / CAT7A): Koresha 0.57mm itwara ogisijeni idafite umuringa, buri jambo ikingiwealuminium foil Mylar kaseti+ muri rusange washyizwemo umuringa wumuringa, kuzamura ubuziranenge bwibimenyetso no gushyigikira 10Gbps yihuta.
Icyiciro cya 8 (CAT8): Imiterere ni SFTP ifite uburyo bwo gukingira ibice bibiri (aluminium foil Mylar kaseti kuri buri jambo + muri rusange), kandi ibyatsi mubisanzwe ni flame-retardant XLPO yamashanyarazi, ishyigikira umuvuduko wa 2000MHz na 40Gbps, bikwiranye no guhuza ibikoresho hagati yikigo.
(2). Ukurikije Imiterere ya Shielding
Ukurikije niba ibikoresho byo gukingira bikoreshwa muburyo, insinga za Ethernet zishobora kugabanywamo:
UTP.
STP.
Imiyoboro ya Marine Ethernet ikunze guhura nimbaraga zikomeye za electromagnetic, bisaba ibikoresho byo gukingira hejuru. Ibikoresho bisanzwe birimo:
F / UTP: Koresha aluminium foil Mylar kaseti nkigice rusange cyo gukingira, kibereye CAT5E na CAT6, gikunze gukoreshwa muri sisitemu yo kugenzura ubwato.
SF / UTP: Aluminium foil Mylar tape + yambaye umuringa wambaye umuringa wambaye ubusa, wongera imbaraga za EMI muri rusange, zikoreshwa cyane mumashanyarazi no kohereza ibimenyetso.
S. Nuburyo busanzwe kuri CAT6A no hejuru yinsinga.
2. Itandukaniro mumashanyarazi ya Ethernet
Ugereranije nubutaka bushingiye kumurongo wa Ethernet, insinga za marine Ethernet zifite itandukaniro rigaragara muguhitamo ibikoresho no mubishushanyo mbonera. Bitewe n’ibidukikije bikabije byo mu nyanja - igihu cyinshi cyumunyu, ubuhehere bwinshi, kwivanga gukomeye kwa electromagnetiki, imirasire ikabije ya UV, hamwe n’umuriro - ibikoresho byinsinga bigomba kuba byujuje ubuziranenge bwo kurinda umutekano, kuramba, no gukora imashini.
(1) .Ibisabwa
Imiyoboro ya Marine Ethernet isanzwe ikorwa ukurikije IEC 61156-5 na IEC 61156-6. Cabling ya horizontal isanzwe ikoresha imiyoboro ikomeye y'umuringa ihujwe nibikoresho bya insuline ya HDPE kugirango igere ku ntera nziza no gutuza; imigozi yamashanyarazi mubyumba byamakuru ikoresha imiyoboro y'umuringa ihagaze hamwe na PO cyangwa PE byoroheje kugirango byoroherezwe ahantu hafunganye.
(2) .Kwirinda umuriro no kurwanya umuriro
Kugira ngo umuriro udakwirakwira, insinga za Ethernet zo mu mazi zikoresha kenshi umwotsi muke wa halogene utagira flame-retardant polyolefin (nka LSZH, XLPO, nibindi) kugirango bogoshe, bahure na IEC 60332 retardant, IEC 60754 (halogen idafite), hamwe na IEC 61034 (umwotsi muke). Kuri sisitemu zikomeye, kaseti ya mika nibindi bikoresho birwanya umuriro byongeweho kugirango byuzuze IEC 60331 irwanya umuriro, bituma ibikorwa byitumanaho bikomeza mugihe cyumuriro.
(3). Kurwanya Amavuta, Kurwanya Ruswa, nuburyo bwintwaro
Mubice byo hanze nka FPSOs na dredgers, insinga za Ethernet zikunze guhura namavuta nibitangazamakuru byangirika. Kugirango tunonosore igihe kirekire, ibikoresho bya polyolefin bihujwe (SHF2) cyangwa ibikoresho birwanya ibyondo SHF2 MUD bikoreshwa, byujuje ubuziranenge bwa NEK 606. Kugirango turusheho kongera imbaraga za mashini, insinga zirashobora gukoreshwa nintoki zicyuma (GSWB) cyangwa icyuma cyumuringa cyometseho (TCWB), gitanga compression nimbaraga zikomeye, hamwe na electromagnetic ikingira kugirango ikingire ubuziranenge bwibimenyetso.
(4). UV Kurwanya no Gusaza
Imiyoboro ya Marine Ethernet ikunze guhura nizuba ryizuba, bityo ibikoresho byicyatsi bigomba kugira imbaraga za UV nziza. Mubisanzwe, polyolefin yogosha hamwe na karubone yumukara cyangwa UV irwanya UV ikoreshwa kandi ikageragezwa munsi ya UL1581 cyangwa ASTM G154-16 UV yubusaza kugirango habeho ituze ryumubiri hamwe nigihe kinini cya serivisi mubuzima bwa UV.
Muri make, buri cyiciro cya marine ya Ethernet igishushanyo mbonera gifitanye isano cyane no guhitamo neza ibikoresho bya kabili. Imiyoboro yumuringa yo mu rwego rwo hejuru, ibikoresho bya insuline ya HDPE cyangwa PO, aluminiyumu foil Mylar kaseti, umuringa wumuringa, icyuma cya mika, ibikoresho bya XLPO, nibikoresho bya SHF2 hamwe nibikoresho bya kabili byitumanaho bishobora guhangana n’ibidukikije bikabije byo mu nyanja. Nkumutanga wibikoresho, twumva akamaro k'ubuziranenge bwibikorwa kumikorere ya kabili yose kandi twiyemeje gutanga ibisubizo byizewe, umutekano, kandi bikora neza kubikorwa byinganda zo mu nyanja no hanze.
