Ib khub ethernet ua haujlwm li cas?
Ib leeg-khub Ethernet tau xub tsim los ua kom tau raws li qhov xav tau ntawm kev lag luam tsheb-me dua, cov kab hluav taws xob sib dua thiab txuas rau kev sib kis los ntawm ntau lub ntsuas hluav taws xob koom nrog hauv kev tswj kev caij nkoj, kev pab nres tsheb, kev tsav tsheb tsis siv neeg, thiab lwm yam hauv tsheb cov ntaub ntawv. Qhov tseeb, qis dua cov ntaub ntawv thauj khoom thiab luv dua qhov yuav tsum tau ua rau daim ntawv thov tsheb tsim nyog rau kev txhim kho SPE thaum ntxov.
Tab sis nrog kev txhim kho thev naus laus zis, lub tuam txhab tau pib pom nws lub peev xwm hauv lwm daim ntawv thov - tshwj xeeb yog kev tsim khoom thiab tsim khoom siv tshuab - thiab tsim kev sib txuas ntawm SPE cov koom tes ua lag luam. Cov chaw tsim khoom' kev koom tes txhawb nqa ib leeg-Ethernet raws li&"; lub hauv paus ntawm IIoT &" thiab txhawb cov qauv rau kev xa cov txheej txheem, thaiv, thiab cov khoom siv.
Ib txwm Ethernet xav tau ob khub ntawm cov xov hlau kom ua tiav cov ntaub ntawv xa tus nqi ntawm 100Mbps, lossis plaub khub ntawm cov xov hlau kom ua tiav qhov kis tau tus mob ntawm 1Gbps. Ib leeg-khub Ethernet siv tsuas yog ib khub ntawm cov xov xa cov ntaub ntawv ntawm tus nqi ntawm 1Gbps, nrog kev sib kis nrug mus txog 40m, lossis kis tus nqi nce mus txog 1000m ntawm 10Mbps-txo qhov loj cable, tus nqi, thiab nyuaj. Txawm hais tias ib txwm muaj Ethernet tau ua tiav thoob plaws hauv lub tshuab siv tshuab, qib qis (qib-qib) cov cuab yeej tseem feem ntau tswj hwm los ntawm cov txheej txheem fieldbus. SPE muab kev daws teeb meem Ethernet uas tuaj yeem ua tiav ntawm txhua qib los ntawm huab mus rau thaj chaw, tshem tawm qhov xav tau ntawm lub qhov rooj thiab lwm yam cuab yeej xav tau rau ntau lub network rau" tham" rau ib leeg
Cov kab hluav taws xob me kuj tseem siv cov txuas me me-lwm qhov txiaj ntsig ntawm SPE hauv qhov chaw txwv tsis pub siv lossis daim ntawv thov-qib nrog ntau yam khoom siv me me. Cov kab hluav taws xob me me muaj qhov khoov me me nyob ib puag ncig, ua rau kev teeb tsa, thaiv thiab tswj hwm tau yooj yim dua thiab hloov pauv tau, ob qho lus thiab ua piv txwv.
SPE tuaj yeem xa hluav taws xob (txog 50W) thiab cov ntaub ntawv, yog li nws tau muab tso ua qhov kev daws teeb meem zoo tshaj plaws rau IIoT daim ntawv thov, qhov twg ntau yam khoom siv hauv thaj tsam xav tau lub zog thiab nrawm, kev sib tham ntawm lub sijhawm tiag tiag nrog kev tswj hwm qib siab lossis mus rau huab. Rau cov ntawv thov uas xav tau ntau dua 50W ntawm lub zog, kev sib xyaw ua ke siv plaub tus neeg siv hluav taws xob tuaj yeem siv, muab txog 96W ntawm 24V lossis 392W ntawm 48V.
Thaum ib txwm muaj Ethernet xav tau plaub khub ntawm cov xov hlau, SPE siv tsuas yog ib khub ntawm cov xov hlau kom ua tiav Ethernet kev sib txuas lus sai npaum li cas?
Classic 1Gbps Ethernet siv Cat5 cables nrog plaub khub ntawm cov xov hlau thiab ua haujlwm ntawm ntau zaus txog li 100MHz. Txhua khub tuaj yeem xa thiab tau txais cov ntaub ntawv, tso cai tus nqi xa mus txog 1Gbps. Ib leeg-khub Ethernet siv tsuas yog ib khub ntawm cov xov hlau, tab sis kev ua haujlwm ntau npaum li 600MHz. Hauv qhov dav dav no, qee qhov xa tawm cov ntaub ntawv, lwm qhov zaus tau txais cov ntaub ntawv, tsuas yog ib khub ntawm cov xov hlau tuaj yeem ua tiav kev sib kis ceev ntawm 1Gbps.
