Nabani na osebenze kwintsimi yoshishino uya kwazi ukuba utshintsho lwamashishini lubizwa ngokuba yi-industrial Ethernet switches. Ukutshintsha kwe-industrial Ethernet yinto esihlala siyibiza ngokuba ziiswitshi zamashishini. Ukutshintsha kwemizi-mveliso kukutshintsha kwemizi-mveliso eyenzelwe ngokukodwa ukuhlangabezana neemfuno zezicelo eziguquguqukayo neziguquguqukayo kwimizi-mveliso. izixhobo, ezibonelela ngeendleko-esebenzayo kwishishini Ethernet isisombululo sonxibelelwano. Ke ngoko, iiswitshi zamashishini zithandwa kakhulu kwishishini. Phakathi kwabo, umsesane unomahluko phakathi kweringi enye kunye ne-multi-ring, kwaye kukho iiprothokholi zeringi zabucala eziyilwe ngabavelisi abahlukeneyo bokutshintsha kwamashishini ngokwesiseko se-STP kunye ne-RSTP, njalo njalo. Ngoko ke zeziphi iingenelo zobugcisa ezingundoqo zokutshintsha kwamashishini?
Ukutshintsha kwemizi-mveliso kunezi nzuzo zilandelayo:
1. Itekhnoloji ye-Zero yokuziphilisa ye-intanethi ukufezekisa ukuthembeka okuphezulu kunye nokunyaniseka kokudluliselwa kwedatha
Ngaphambi koku, elona xesha likhawulezayo lokuziphilisa lokutshintsha kwamashishini kwihlabathi kwakuyi-20 millisecond. Nangona kunjalo, kungakhathaliseki ukuba ixesha lokuziphilisa lifutshane kangakanani impazamo yenethiwekhi yendandatho, ngokuqinisekileyo kuya kubangela ukulahlekelwa kweepakethi zedatha ngexesha lokutshintsha, elingenakunyamezela kwinqanaba lomyalelo wokulawula. I-Zero yokuziphilisa ngokungathandabuzekiyo ifezekisa impumelelo kwiiteknoloji ezikhoyo kwaye iqinisekisa ukuthembeka okuphezulu kunye nokuthembeka kwedatha.
Ukutshintsha kwamashishini kuqinisekisa ukuba xa inethiwekhi ingaphumeleli, kukho rhoqo isalathiso esisodwa sokufikelela kwindawo ekuya kuyo ngokusebenzisa ukuhamba kwedatha ye-bidirectional, ukuqinisekisa idatha yokulawula engaphazamisekiyo.
2. Inethiwekhi yohlobo lwebhasi iqaphela ukuhlanganiswa kwenethiwekhi kunye nomgca
Inethiwekhi yebhasi ivumela abasebenzisi ukuba benze isixhobo esilawulwayo. Ngokuphatha i-terminal ye-Mac efanayo njengesixhobo esifanayo, iswitshi ijonga isixhobo esilawulwa njengesixhobo esifanayo, ukuze ezi zixhobo zidityaniswe kunye nolwazi olwabiweyo, oluqinisekisa unxibelelwano lolawulo. .
Iiswitshi zemizi-mveliso zixhasa iindidi ngeendidi zeeprothokholi zebhasi kunye nojongano lwe-I/O ukuqonda uthungelwano lwedatha yebhasi. Esikhundleni sendlela engeyiyo yendabuko yokubeka indawo, yandisa inethiwekhi kunye nokusetyenziswa kwezixhobo zebhasi. Ngaphezu koko, ukucwangciswa kwenethiwekhi okuguquguqukayo kunokufezekiswa, okunokuthi kuqhagamshelwe ngokuthe ngqo kwizixhobo zentsimi ezifana nezixhobo kunye neekhamera zoshishino, ukwenzela ukuba i-PLC ixhunywe kwizixhobo ze-I / O ezikude, ezinciphisa kakhulu inani le-PLCs kwinkqubo yonke kwaye kunciphisa kakhulu iindleko zokudityaniswa kwenkqubo. . Ukongeza, ukutshintshwa kwemizi-mveliso kunokudityaniswa kwisoftware yokubeka iliso kwinethiwekhi ngeWebhu kunye ne-SNMP OPC Server ukujonga imeko ye-node ngexesha langempela, kwaye ibe nomsebenzi we-alarm onempazamo ukuququzelela ukugcinwa nokulawulwa kude.
3. Ukukhawuleza kunye nexesha langempela
Ukutshintsha kwemizi-mveliso kunokubaluleka kwedatha, evumela abasebenzisi ukuba benze izixhobo ezithile njengezixhobo zedatha ezikhawulezayo. Xa idatha ekhawulezayo ivela kwinethiwekhi yeringi, idatha eqhelekileyo iya kwenza indlela yedata ekhawulezayo. Yiphephe imeko ukuba utshintsho lwemveli alunakusetyenziswa kuluhlu lomyalelo wolawulo ngenxa yokulibaziseka okukhulu kwedatha
