Namuhla, ngokuthuthuka okusheshayo kobuchwepheshe bokushintshwa kwezimboni, busetshenziswa kabanzi emikhakheni eminingi, ikakhulukazi emikhakheni emithathu yamandla, ezokuthutha, kanye ne-metallurgy.Kwaziwa njengezimboni ezintathu ezingaba khona zezicelo zokushintshwa kwezimboni.Kusukela isiceloukushintshwa kwezimboniNgohlu olubanzi kangaka lwezinkambu, yiziphi izici nezinzuzo zokushintshwa kwezimboni?

1. Kuyini ukushintshwa kwezimboni?
Okokuqala, ake siqonde ukuthi yini ukushintsha kwezimboni?Ukushintshwa kwezimboni kubizwa nangokuthi ama-switch Ethernet wezimboni.Ngenxa yesimo sawo esikhethekile sokusebenza kanye nezidingo zokusebenza, amaswishi ezimboni anezici eziningi ezingatholakali kumaswishi avamile noma ezentengiso.Banochungechunge lomkhiqizo ocebile kanye nokucushwa kwembobo okuguquguqukayo, okungahlangabezana nezilawuli ezihlukahlukene zezimboni.Izimfuneko zokusebenzisa inkambu.

2. Yiziphi izinzuzo eziyinhloko zemikhiqizo yokushintsha izimboni?
I-1) .Ukusebenzisa izingxenye zebanga lezimboni: Ukushintsha kwezimboni kunezidingo eziphezulu zokukhethwa kwezingxenye futhi kufanele zimelane nezimo ezinzima.Ngakho-ke, bangakwazi ukuzivumelanisa kahle nezimo zezimboni futhi basekele izinhlelo zokusebenza zezimboni ezindaweni ezihlukahlukene ezinokhahlo.
2).Inethiwekhi yendandatho esheshayo kanye nokuqedwa kabusha okusheshayo: Amaswishi emboni ngokuvamile anenethiwekhi yokukhala esheshayo nemisebenzi yokuphinda ingasebenzi, futhi isikhathi sohlelo singaba ngaphansi kuka-50ms.Nakuba imikhiqizo yezentengiselwano ingase futhi yakhe inethiwekhi engasebenzi, isikhathi sokuziphilisa singaphezu kwe-10-30s, engakwazi ukuhlangabezana nokusetshenziswa kwezindawo zezimboni.Isibonelo, isikhathi sokuziphilisa sokushintsha kwenethiwekhi yendandatho yezimboni eyakhiwe futhi ekhiqizwa yi-Utepu okungenani i-20ms.
3).Ukusebenza okuphezulu kokumelana nokuphazamiseka: Amaswishi ebanga lemboni anamandla okumelana nokuphazamiseka, angasebenza ezindaweni ezinozibuthe zikagesi, futhi abe namazinga aphezulu okuvikela umbani, ukuvikela amanzi, ukubola, ukunqanda ukugqwala, ukunqanda umthelela, ukunqanda ukuqina, njll. Izinga lokuvikela , kuyilapho amaswishi ebanga lezentengiso engenazo lezi zici.Ngokwesibonelo,I-JHA's 8-port POE full switch yemboni ye-Gigabitinamandla okuvikela umbani we-6KV, ukuvikelwa kwezimboni 4-level namandla okulwa nokuphazamiseka.
4).Zijwayelane nendawo ebanzi yokushisa: Amaswishi emboni ngokuvamile asebenzisa igobolondo lensimbi ewuthayela, elinokukhipha ukushisa okungcono nokuvikela okuqinile.Ingasebenza ngokujwayelekile ezingeni lokushisa elingu-40°C—+75°C, futhi ikwazi ukuzivumelanisa kahle nezimo eziyinkimbinkimbi.Nomswakama.Nokho, imikhiqizo eshintshayo yezentengiselwano ingasebenza kuphela ku-0°C—+50°C, engakwazi ukuhlangabezana nezidingo zokusebenza ezimweni zezulu ezinzima.
5).Idizayini yokunikezwa kwamandla angasebenzi: Ukunikezwa kwamandla kuyingxenye ebaluleke kakhulu yokushintsha kwezimboni.Ukwehluleka kwamandla ngokuvamile kubalela ngaphezu kwama-35% wezinga lokuhluleka kwezisetshenziswa.Ukuze kugwenywe izinkinga ezibangelwa ukwehluleka kukagesi, amaswishi ezimboni athatha idizayini ekabili yokuphelelwa umsebenzi ukuze kuqinisekiswe ukusebenza okuzinzile nokuthembekile kwesistimu.Imikhiqizo yezentengiso ngokuvamile isebenzisa ugesi owodwa we-AC, ongafanele ukusetshenziswa ezindaweni zezimboni.
6).Impilo ende yesevisi: Ukushintsha kwezimboni kusebenzisa izixazululo zezinga lezimboni kusukela ezintweni zezindlu kuya ezintweni ezisekelayo, ngakho umkhiqizo unokuthembeka okuphezulu nempilo ende yesevisi.Impilo yesevisi ejwayelekile> iminyaka eyi-10, kanti impilo yesevisi yokushintsha okujwayelekile kwezentengiselwano ingu-3. -5 iminyaka.

I-Ethernet yosiko ayakhelwe izinhlelo zokusebenza zezimboni.Ekuqaleni komklamo, ukuguquguquka kwemvelo yensimu yezimboni akuzange kucatshangelwe.Ngakho-ke, lapho kubhekene nezindawo zokusebenza ezinzima ezifana nesimo sezulu nothuli, ukuzinza kwamaswishi ezentengiselwano ezivamile Kuyoba inselele enkulu.Ukuvela kokushintshwa kwezimboni kuxazulula izinkinga eziningi zokuvuleka, isikhathi sangempela, ukuvumelanisa, ukwethembeka, ukulwa nokuphazamiseka kanye nokuphepha, futhi kuba ithuluzi lokudlulisela elingakwazi ukuzivumelanisa nezimo eziyinkimbinkimbi zezimboni futhi kube lula ukuthunyelwa kwamanethiwekhi ezishintshayo zezimboni.
