Kule mihla, kunye nophuhliso olukhawulezayo lobuchwepheshe bokutshintsha kwemizi-mveliso, lusetyenziswa kakhulu kwiinkalo ezininzi, ngakumbi kwiinkalo ezintathu zamandla, ezothutho, kunye nesinyithi.Kwaziwa njengamashishini amathathu anokubakho kwizicelo zokutshintsha kweshishini.Ukususela ekusetyenzisweni kweiiswitshi zamashishiniNgoluhlu olubanzi kangaka lwamasimi, zeziphi iimpawu kunye neenzuzo zokutshintsha kwamashishini?

1. Yintoni utshintsho lwamashishini?
Okokuqala, masiqonde ukuba yintoni iswitshi yeshishini?Ukutshintsha kwamashishini kukwabizwa ngokuba ziiswitshi ze-Ethernet zeshishini.Ngenxa yemekobume yabo ekhethekileyo yokusebenza kunye neemfuno zokusebenza, iiswitshi zemizi-mveliso zineempawu ezininzi ezingafumanekiyo kwizitshixo zabahlali kunye nezorhwebo.Banoluhlu lweemveliso ezityebileyo kunye noqwalaselo lwezibuko oluguquguqukayo, olunokuthi luhlangabezane nolawulo lwamashishini ahlukeneyo.Iimfuno zokusetyenziswa kwentsimi.

2. Ziziphi iingenelo eziphambili zeemveliso zokutshintsha kwamashishini?
I-1) .Ukusebenzisa amacandelo ebakala loshishino: Ukutshintsha kwemizi-mveliso kuneemfuno eziphezulu zokukhethwa kwecandelo kwaye kufuneka zimelane neendawo ezinzima.Ke ngoko, banokuziqhelanisa kakuhle nemeko yemigangatho yemizi-mveliso kwaye baxhase usetyenziso lwamashishini kwiindawo ezahlukeneyo ezinzima.
2).Uthungelwano lwendandatho ekhawulezayo kunye nokuphindaphinda ngokukhawuleza: Ukutshintsha kwemizi-mveliso ngokuqhelekileyo kunothungelwano lwendandatho ekhawulezayo kunye nemisebenzi yokunciphisa ngokukhawuleza, kwaye ixesha lokunciphisa inkqubo linokuba ngaphantsi kwe-50ms.Nangona iimveliso zorhwebo zinokwenza inethiwekhi engafunekiyo, ixesha lokuziphilisa lingaphezulu kwe-10-30s, elingenako ukuhlangabezana nokusetyenziswa kweendawo zoshishino.Ngokomzekelo, ixesha lokuziphilisa lokutshintsha kwenethiwekhi ye-industrial ring ephuhliswe kwaye iveliswe ngu-Utepu ubuncinane i-20ms.
3).Ukusebenza okuphezulu kokuchasana nokuphazamiseka: Ukutshintsha kwe-Industrial-grade kunokusebenza okunamandla okuchasana nokuphazamiseka, kunokusebenza kwiindawo ezinzima ze-electromagnetic, kwaye zinezinga eliphezulu lokukhusela umbane, ukuthintela amanzi, ukuchasana nokubola, ukuchasana kwempembelelo, i-anti-static, njl. , ngelixa i-switch-grade switches ayinazo ezi mpawu.Umzekelo,I-JHA ye-8-port ye-POE epheleleyo ye-Gigabit yokutshintsha kwamashishiniinokhuseleko lombane lwe-6KV, ukhuseleko lwenqanaba lesi-4 kunye namandla okuchasana nokuphazamiseka.
4).Ukuqhelanisa nemekobume yobushushu ebanzi: Ukutshintsha kwemizi-mveliso ngokuqhelekileyo kusebenzisa iqokobhe lesinyithi eligutyungelwe, elinokuphelisa ubushushu obungcono kunye nokhuseleko olunamandla.Inokusebenza ngokuqhelekileyo kumaqondo obushushu angama-40°C—+75°C, yaye iyakwazi ukuziqhelanisa kakuhle namaqondo obushushu antsonkothileyo.Nokufuma.Nangona kunjalo, iimveliso zokutshintsha urhwebo zinokusebenza kuphela kuluhlu lwe-0 ° C—+ 50 ° C, olungenako ukuhlangabezana neemfuno zokusebenza kwiimeko zemozulu ezinzima.
5).Uyilo lonikezelo lwamandla ayimfuneko: Unikezelo lwamandla luyinxalenye ebaluleke kakhulu yokutshintsha kweshishini.Ukungaphumeleli kwamandla ngokuqhelekileyo kubalela ngaphezu kwe-35% yezinga lokungaphumeleli kwezixhobo.Ukuze kuthintelwe inkathazo ebangelwa kukungaphumeleli kombane, iiswitshi zemizi-mveliso zamkela uyilo oluphindwe kabini lonikezelo lwamandla ombane ukuqinisekisa ukusebenza okuzinzileyo nokuthembekileyo kwenkqubo.Iimveliso zorhwebo ngokubanzi zisebenzisa umbane omnye we-AC, ongafanelanga usetyenziso kwiindawo zoshishino.
6).Ubomi benkonzo ende: Ukutshintsha kwemizi-mveliso kwamkela izisombululo zemigangatho yemizi-mveliso ukusuka kwizinto zezindlu ukuya kumacandelo axhasayo, ngoko ke imveliso inokuthembeka okuphezulu kunye nobomi benkonzo obude.Ubomi benkonzo jikelele ngu> iminyaka eyi-10, ngelixa ubomi benkonzo yokutshintshwa kwezorhwebo eziqhelekileyo yi-3. -5 iminyaka.

I-Ethernet yesiNtu ayenzelwanga ukusetyenziswa kwezoshishino.Ekuqaleni koyilo, ukulungelelaniswa kwemeko yendawo yezoshishino akuzange kuthathelwe ingqalelo.Ngoko ke, xa ujongene neendawo zokusebenza ezinzima ezifana nemozulu kunye nothuli, ukuzinza kweenguqu eziqhelekileyo zorhwebo Kuya kuba ngumngeni omkhulu.Ukuvela kokutshintsha kwamashishini kusombulula iingxaki ezininzi zokuvuleleka, ixesha langempela, ukuvumelanisa, ukuthembeka, ukuchasana nokuphazamiseka kunye nokhuseleko, kwaye ibe sisixhobo sokuhambisa esinokuthi sivumelane neendawo eziyinkimbinkimbi zoshishino kunye nokuququzelela ukuthunyelwa kweenethiwekhi ze-automation networks.
