Noma ubani oke wasebenza emkhakheni wezimboni uzokwazi ukuthi ukushintshwa kwezimboni kubizwa ngokuthi ama-industrial Ethernet switch. Amaswishi e-Industrial Ethernet yilokho esivame ukukubiza ngokuthi ukushintshwa kwezimboni. Ukushintsha kwezimboni kuwukushintsha kwezimboni eziklanyelwe ngokukhethekile ukuhlangabezana nezidingo zezinhlelo zokusebenza zezimboni eziguquguqukayo nezishintshayo. imishini, ehlinzeka ngesisombululo sokuxhumana se-Ethernet yezimboni esingabizi kakhulu. Ngakho-ke, ukushintshwa kwezimboni kuthandwa kakhulu embonini. Phakathi kwazo, indandatho inomehluko phakathi kwendandatho eyodwa kanye ne-multi-ring, futhi kukhona nemigomo yendandatho yangasese eklanywe abakhiqizi abahlukahlukene bokushintshwa kwezimboni ngesisekelo se-STP ne-RSTP, njalonjalo. Ngakho yiziphi izinzuzo zobuchwepheshe eziyinhloko zokushintshwa kwezimboni?
Ukushintshwa kwezimboni kunezinzuzo ezilandelayo:
1. Ubuchwepheshe benethiwekhi yendandatho yokuziphilisa engu-Zero ukuze kuzuzwe ukwethembeka okuphezulu nobuqotho bokudluliswa kwedatha
Ngaphambi kwalokhu, isikhathi sokuziphilisa esisheshayo sokushintshwa kwezimboni emhlabeni sasingama-millisecond angama-20. Kodwa-ke, kungakhathaliseki ukuthi isikhathi sokuziphilisa sephutha lenethiwekhi yendandatho sifushane kangakanani, nakanjani kuzobangela ukulahlekelwa kwamaphakethe wedatha ngesikhathi sokushintsha, okungenakubekezelelwa kungqimba lomyalo wokulawula. Ukuzilapha ngokwakho ngaphandle kokungabaza kuzuza impumelelo kubuchwepheshe obukhona futhi kuqinisekisa ukwethembeka okuphezulu nobuqotho bedatha.
Ukushintsha kwezimboni kuqinisekisa ukuthi uma inethiwekhi yehluleka, kuhlale kunesiqondiso esisodwa sokufinyelela indawo ngokugeleza kwedatha eqondiswa kabili, iqinisekisa idatha yokulawula engaphazamiseki.
2. Inethiwekhi yohlobo lwebhasi ibona ukuhlanganiswa kwenethiwekhi nolayini
Inethiwekhi yebhasi ivumela abasebenzisi ukuthi benze ngendlela oyifisayo idivayisi elawulwayo. Ngokuphatha itheminali ye-Mac efanayo njengedivayisi efanayo, iswishi ibheka idivayisi elawulwayo njengedivayisi efanayo, ukuze lawa madivayisi axhumeke futhi kwabelwane ngolwazi, okuqinisekisa ukuxhumana kokulawula. .
Ukushintsha kwezimboni kusekela izinqubo ezihlukahlukene zamabhasi kanye nezindawo zokusebenzelana ze-I/O ukuze kuqashelwe ukuxhumana kwedatha yebhasi. Esikhundleni semodi yephoyinti nephoyinti engeyona eyendabuko, khulisa ukusetshenziswa kwenethiwekhi nensiza yebhasi. Ngaphezu kwalokho, ukucushwa kwenethiwekhi okuguquguqukayo kungenziwa, okungaxhunyaniswa ngokuqondile kumadivayisi wensimu afana nezinsimbi namakhamera ezimboni, ukuze i-PLC ixhunywe kumadivayisi we-I / O akude, okunciphisa kakhulu inani lama-PLC kulo lonke uhlelo futhi kunciphisa kakhulu izindleko zokuhlanganiswa kwesistimu. . Ngaphezu kwalokho, ukushintshwa kwezimboni kungabuye kuhlanganiswe nesofthiwe yokuqapha inethiwekhi nge-Web kanye ne-SNMP OPC Server ukuze kuqashwe isimo se-node ngesikhathi sangempela, futhi kube nomsebenzi we-alamu onephutha ukuze kube lula ukugcinwa nokuphathwa okukude.
3. Fast and real-time
Ukushintsha kwezimboni kunesici esibalulekile sedatha, esivumela abasebenzisi ukwenza ngendlela oyifisayo amadivayisi athile njengamadivayisi edatha asheshayo. Uma idatha esheshayo ivela kunethiwekhi yokukhala, idatha evamile izovula indawo yedatha esheshayo. Gwema isimo sokuthi ukushintsha okuvamile akukwazi ukusetshenziswa kungqimba lomyalo wokulawula ngenxa yokulibaziseka okweqile kwedatha
