Industrial keyboardstau tsim tshwj xeeb los ua kom tau raws li qhov xav tau ntawm kev hloov pauv thiab hloov pauv kev lag luam thiab muab kev lag luam zoo Ethernet kev daws teeb meem.Cov keyboards muaj, raws li peb cov cuab yeej siv LAN kho vajtse, yeej ib txwm paub rau txhua tus.Nws cov koob meej yog qhov tseeb vim yog kev siv Ethernet dav, raws li niaj hnub no cov khoom siv Ethernet tseem ceeb, yuav muaj cov cuab yeej zoo li no hauv yuav luag txhua lub network hauv zos.

Cov keyboards muaj kev hloov pauv raws li Ethernet xa cov ntaub ntawv, thiab Ethernet siv ib cheeb tsam hauv cheeb tsam uas sib koom cov tsheb npav-hom kis nruab nrab.Tus qauv ntawm Ethernet hloov yog tias txhua qhov chaw nres nkoj txuas ncaj qha rau tus tswv tsev, thiab feem ntau ua haujlwm hauv hom puv-duplex.Qhov hloov pauv tuaj yeem txuas mus rau ntau lub chaw nres nkoj tib lub sijhawm, kom txhua khub ntawm cov tswv uas sib txuas lus tuaj yeem xa cov ntaub ntawv tsis muaj teeb meem xws li nws yog qhov nruab nrab kev sib txuas lus tshwj xeeb.Saib ntawm cov topology hauv qab no, koj yuav pom tias thaum siv lub hnub qub topology, yuav muaj kev hloov pauv hauv Ethernet, vim tias txhua tus tswv tau txuas nrog kev hloov pauv siv cov cables los txuas rau ib leeg.

Qhov tseeb, nyob rau hauv lub hnub qub tshaj plaws topology, tus qauv cable centralized kev twb kev txuas ntaus ntawv yog "HUB (hub)", tab sis hubs muaj teeb meem xws li kev sib koom bandwidth, tsis sib haum xeeb ntawm cov chaw nres nkoj, vim hais tias txhua leej txhua tus paub tias tus qauv Ethernet yog "hub".Kev tsis sib haum xeeb network" txhais tau hais tias nyob rau hauv lub npe hu ua "kev sib cav sib ceg", feem ntau ob lub nodes tuaj yeem sib txuas lus nrog ib leeg.Ntxiv mus, txawm hais tias lub hub muaj ntau qhov chaw nres nkoj, nws cov qauv sab hauv yog tag nrho lub npe hu ua "cov qauv tsheb npav" ntawm Ethernet, uas txhais tau hais tias tsuas muaj ib "kab" sab hauv rau kev sib txuas lus.Yog tias koj siv lub hub ntaus ntawv, piv txwv li, yog cov nodes ntawm cov chaw nres nkoj 1 thiab 2 yog kev sib txuas lus, lwm qhov chaw nres nkoj yuav tsum tau tos.Qhov tshwm sim ncaj qha yog, piv txwv li, nws yuav siv sijhawm 10 feeb los xa cov ntaub ntawv ntawm cov nodes txuas nrog cov chaw nres nkoj 1 thiab 2, thiab cov nodes qhov chaw nres nkoj 3 thiab 4 nyob rau tib lub sijhawm kuj pib xa cov ntaub ntawv los ntawm lub hub no, tsis sib haum xeeb. nrog rau ib leeg, ua rau txhua tus neeg xav tau Lub sijhawm yuav ntev dua, thiab nws yuav siv sijhawm li 20 feeb kom ua tiav qhov kev sib kis.Qhov ntawd yog hais tias, ntau qhov chaw nres nkoj ntawm lub hub uas sib txuas lus nrog ib leeg, qhov teeb meem loj dua, thiab nws yuav siv sij hawm ntev dua los xa cov ntaub ntawv.

Cov yam ntxwv ntawm lub cev ntawm cov keyboards muaj xws li cov yam ntxwv zoo li, cov yam ntxwv ntawm kev sib txuas ntawm lub cev, kev teeb tsa chaw nres nkoj, hom puag, muaj peev xwm nthuav dav, muaj peev xwm stacking thiab qhov taw qhia qhov chaw muab los ntawm kev hloov, uas cuam tshuam qhov xwm txheej ntawm qhov hloov pauv.

Lub tshuab hloov pauv yog cov khoom siv hloov nrog cov yam ntxwv ntawm kev yooj yim, tus nqi qis, kev ua haujlwm siab thiab qhov chaw nres nkoj siab, uas embodies lub complex switching technology ntawm bridging technology nyob rau hauv lub thib ob txheej ntawm OSI siv qauv.Zoo li tus choj, qhov hloov pauv ua qhov kev txiav txim siab yooj yim rau xa cov ntaub ntawv raws li MAC chaw nyob hauv txhua pob ntawv.Thiab qhov kev txiav txim xa mus no feem ntau tsis xav txog lwm cov ntaub ntawv sib sib zog nqus zais hauv pob ntawv.Qhov sib txawv nrog cov txuas txuas yog tias qhov hloov pauv xa mus qeeb me me, ze rau qhov kev ua tau zoo ntawm ib leeg LAN, thiab deb tshaj qhov kev xa mus ntawm kev sib txuas sib txuas zoo tib yam.

Kev siv thev naus laus zis tso cai rau kev hloov kho bandwidth rau kev sib koom thiab kev mob siab rau LAN ntu kom txo qis hauv kev khiav ntawm cov ntaub ntawv ntawm LANs.Muaj kev hloov khoom ntawm Ethernet, Fast Ethernet, FDDI thiab ATM thev naus laus zis.

Kev siv cov kev sib txuas tshwj xeeb uas tsim los ua kom muaj kev hloov pauv mus rau cov ntaub ntawv xa mus rau tib lub sijhawm ntawm txhua qhov chaw nres nkoj ntawm tus nqi kab, muab kev ua tau zoo dua li cov txuas hniav ib txwm muaj.Daim ntawv thov tshwj xeeb hauv kev sib xyaw ua ke thev naus laus zis tso cai rau kev hloov mus rau kev ua haujlwm nrog cov lus hais saum toj no thaum muaj ntau qhov chaw nres nkoj, thiab nws qhov chaw nres nkoj nqi qis dua li ntawm tus choj ib txwm muaj.

Muaj cov keyboards tau siv dav.Nyob rau hauv cov nqe lus ntawm kev lag luam daim ntawv thov, lawv tsuas yog siv nyob rau hauv: thee mine kev nyab xeeb, rail transit, Hoobkas automation, dej kho tshuab, kev ruaj ntseg hauv nroog, thiab lwm yam.
