Kwiminyaka yakutshanje, kukho iintlobo ezininzi zeiiswitshi zamashishini, ezisetyenziswa ngokubanzi kwiinkalo ezininzi, ezifana: ukuthuthwa okuhlakaniphile, ukuhamba ngomzila kaloliwe, amandla ombane, imigodi kunye nezinye iindawo. Ngenxa yesidingo sokuqwalasela izinto ezininzi, ezifana nemeko yomsebenzi, nokuba ukuchithwa kwemisebenzi kuyafuneka, ulawulo lwenethiwekhi kunye nolawulo olungelulo lwenethiwekhi, ukugcinwa kwexesha elizayo kunye nokunciphisa, njl. Ngoko ke, xa sikhetha ukutshintsha kwemizi-mveliso, kufuneka siyiqwalasele ngokubanzi. ngokwemeko yethu.

1. Ixesha langempela: Ukuhanjiswa kwedatha yenethiwekhi kuya kuvelisa ukulibaziseka okuthile. Ngoko ke, xa ukhetha ukutshintshwa kwe-Ethernet yoshishino, ukulibaziseka kwechweba kwinkqubo yokuhanjiswa kwesakhelo sedatha kufuneka kuthathelwe ingqalelo;

2. Ukuthembeka: Kwimeko yendawo yoshishino, ukuthembeka kubaluleke kakhulu; kwinkcazo yeparameter yemveliso, kufuneka kubekho inkcazo ecacileyo yoluhlu lobushushu obusebenzayo, ukhuseleko lwe-electromagnetic, kunye nenqanaba lokukhusela umbane;

3. Ukuhambelana: Ukutshintsha kwamashishini kunye namanye amacandelo e-Ethernet yezoshishino kufuneka akwazi ukunxibelelana ngokusebenzisa i-protocol ye-TCP / IP eqhelekileyo. Naphantsi kwaziphi na iimeko kufuneka kubekho ukungahambelani phakathi kwezixhobo ze-Industrial Ethernet kunye nezixhobo ze-Ethernet zorhwebo. Ngokuhambelana nezisombululo zebhasi zentsimi ezahlukeneyo, izixhobo ze-Ethernet zamashishini kufuneka zibe nezakhono ezihambelanayo ukuze zihambelane nazo.

Ukongeza, xa ukhetha i-industrial switch, isibini esijijekileyo esifanelekileyo okanye i-fiber interface kufuneka kwakhona ikhethwe ngokweemfuno ezisisiseko ezifana nomgama wothumelo kunye ne-bandwidth yokuhambisa.

Ukutshintsha kwamashishini eJHAsebenzisa amacandelo omgangatho wemizi-mveliso, inethiwekhi yeringi ekhawulezayo, ukuphelelwa ngamandla, ukusebenza okuphezulu kokuchasana nokuphazamiseka, ukuziqhelanisa nemekobume yobushushu ebanzi, efanele ukuthenjwa kunye nokukhetha kwakho..
