Xyoo tas los no, vim muaj tej yam tsis paub meej xws li tus kab mob coronavirus tshiab, kev tsis txaus ntawm cov khoom siv, thiab tus nqi khoom siv raw nce siab, txhua tus neeg hauv lub neej tau ntsib teeb meem loj heev, tab sis cov khoom siv network thiab lub tshuab hloov pauv hauv nruab nrab tsis raug cuam tshuam ntau. Kev cia siab tias kev lag luam hloov pauv yuav loj hlob tas mus li rau lub sijhawm tom ntej.
Kev hloov pauv hauv kev lag luam yog lub hauv paus ntawm kev sib txuas lus hauv kev lag luam. Cov hloov pauv, yog tias muab faib raws li qhov chaw ua haujlwm, tuaj yeem muab faib ua cov hloov pauv theem lag luam thiab cov hloov pauv theem kev lag luam. Tus thawj coj yog siv rau hauv chaw ua haujlwm xws li cov tuam txhab thiab cov tsev, thaum tus tom kawg yog qhov tsim nyog rau cov chaw ua haujlwm nrog cov chaw ib puag ncig hnyav.
Tam sim no, qhov siv dav tshaj plaws hauv kev ua lag luam yog qhov hloov pauv kev lag luam, thiab nyob rau lub sijhawm ntawm Is Taws Nem ntawm Txhua Yam, nws tseem hu ua lub hauv paus ntawm kev sib txuas lus kev lag luam, yog li thaum tham txog qhov hloov pauv, nws feem ntau hais txog qhov hloov pauv kev lag luam.
Cov keyboards kev lag luam yog ib hom keyboards tshwj xeeb, piv rau cov keyboards ib txwm muaj. Feem ntau lawv tsim nyog rau cov chaw ua lag luam uas muaj qhov chaw nyuaj thiab hloov pauv tau, xws li qhov kub thiab txias tsis tuaj yeem tswj tau (tsis muaj cua txias, tsis muaj ntxoov ntxoo), plua plav hnyav, muaj kev pheej hmoo ntawm nag, qhov xwm txheej teeb tsa tsis zoo thiab qhov chaw muab hluav taws xob tsis zoo, thiab lwm yam.
Nws yog ib qho tsim nyog sau tseg tias nyob rau hauv daim ntawv thov ntawm kev saib xyuas sab nraum zoov, cov hloov pauv kev lag luam kuj xav tau POE ua haujlwm. Vim tias qhov hloov pauv kev lag luam saib xyuas sab nraum zoov xav tau lub koob yees duab sab nraud lossis lub koob yees duab dome, thiab qhov chaw ib puag ncig muaj kev txwv, nws tsis yooj yim sua kom nruab lub zog rau cov koob yees duab no. Yog li ntawd, POE tuaj yeem muab lub zog rau lub koob yees duab los ntawm lub network cable, uas daws qhov teeb meem ntawm kev muab hluav taws xob. Tam sim no ntau lub nroog siv hom kev hloov pauv kev lag luam no nrog POE fais fab mov.
Hais txog kev siv hauv tsev, lub zog hluav taws xob thiab kev thauj mus los ntawm tsheb ciav hlau yog cov teb tseem ceeb ntawm kev siv cov khoom siv hloov pauv hauv kev lag luam. Raws li cov ntaub ntawv, lawv tau suav txog li 70% ntawm kev lag luam hauv tsev.
Ntawm lawv, kev lag luam fais fab yog qhov tseem ceeb tshaj plaws ntawm kev siv cov khoom siv hloov pauv hauv kev lag luam. Thaum kev lag luam txuas ntxiv hloov mus rau kev txawj ntse, ua haujlwm tau zoo, txhim khu kev qha thiab ntsuab kev loj hlob, kev nqis peev sib xws yuav txuas ntxiv mus.
Kev lag luam thauj mus los yog kev lag luam thov thib ob loj tshaj plaws ntawm kev hloov pauv kev lag luam. Nyob rau hauv xyoo tas los no, nrog rau kev nce ntxiv ntawm kev nqis peev hauv kev tsheb ciav hlau ceev ceev thiab kev thauj mus los hauv nroog, nrog rau kev txhim kho ntxiv ntawm kev txawj ntse thiab kev siv tshuab hauv kev loj thiab lwm yam kev thauj mus los, kev lag luam hloov pauv kev lag luam hauv kev lag luam thauj mus los tau tswj hwm kev loj hlob sai.
Yav tom ntej, nrog rau kev nce qib tas mus li ntawm cov txheej txheem automation hauv kev lag luam thiab kev txhawb nqa tas mus li ntawm kev siv tshuab Ethernet hauv kev lag luam, kev hloov pauv hauv kev lag luam yuav coj mus rau kev txhim kho ntau dua. Los ntawm qhov kev xav ntawm kev siv tshuab, kev sib txuas lus tiag tiag, kev ruaj khov thiab kev ruaj ntseg yog qhov tseem ceeb ntawm cov khoom lag luam Ethernet hloov pauv. Los ntawm qhov kev xav ntawm cov khoom, ntau lub luag haujlwm yog qhov kev coj ua ntawm kev txhim kho ntawm kev hloov pauv hauv kev lag luam.
Nrog rau kev txhim kho tas mus li thiab kev loj hlob ntawm cov thev naus laus zis hloov pauv kev lag luam, cov cib fim rau cov hloov pauv yuav tawg dua. Xiamen Tongkong, ua tus neeg sawv cev ntawm cov khoom lag luam hauv tsev thiab thoob ntiaj teb nto moo, xws li Hirschmann, MOXA, yuav tsum tau nkag siab txog qhov sib txawv ntawm kev txhim kho thiab ua kev npaj ua ntej.
