Yeyiphi into yokuqala ethi qatha engqondweni xa ucinga ngegama elithi BUS?Mhlawumbi inkulu, ibhasi yetshizi etyheli okanye inkqubo yakho yezothutho yasekuhlaleni.Kodwa kwintsimi yobunjineli bombane, oku akunanto yakwenza nesithuthi.I-BUS sisishunqulelo se-“Binary Unit System”."I-Binary Unit System" isetyenziselwa ukudlulisa idatha phakathi kwabathathi-nxaxheba kwinethiwekhi ngoncedo lweiintambo.Kule mihla, iinkqubo ze-BUS zisemgangathweni kunxibelelwano lwamashishini, olungenakucingelwa ngaphandle kwabo.
Yaqala njani yonke loo nto
Unxibelelwano lwemizi-mveliso luqale ngocingo olunxuseneyo.Bonke abathathi-nxaxheba kwinethiwekhi baxhunywe ngokuthe ngqo kwinqanaba lokulawula kunye nokulawula.Ngokunyuka kwe-automation, oku kwakuthetha umzamo wokuhlala ukhula we-wiring.Namhlanje, unxibelelwano lwamashishini lusekwe ikakhulu kwiinkqubo zebhasi okanye uthungelwano olusekwe kwi-Ethernet.
Fieldbus
"Izixhobo zentsimi," ezifana ne-sensor kunye ne-actuators, ziqhagamshelwe kwisilawuli sengqiqo esicwangcisiweyo (esaziwa ngokuba yi-PLC) ngokusebenzisa ii-wire, i-serial fieldbuses.I-fieldbus iqinisekisa ukutshintshiselana kwedatha ngokukhawuleza.Ngokwahlukileyo kwi-wiring ehambelanayo, i-fieldbus inxibelelana kuphela ngentambo enye.Oku kunciphisa kakhulu iinzame zocingo.I-fieldbus isebenza ngokomgaqo wenkosi-khoboka.Inkosi inoxanduva lokulawula iinkqubo kunye nenkqubo yekhoboka imisebenzi elindileyo.
Ii-Fieldbuses ziyahluka kwi-topology yazo, iiprothokholi zothumelo, ubude bothumelo oluphezulu kunye nesixa esikhulu sedatha ngetelegram.I-topology yenethiwekhi ichaza ilungiselelo elithile lezixhobo kunye neentambo.Ukwahlula kwenziwa apha phakathi kwetopology yomthi, inkwenkwezi, intambo okanye i-ring topology.I-fieldbuses ezaziwayo ziProfibusokanye CANopen.Iprothokholi ye-BUS yiseti yemigaqo apho unxibelelwano lwenzeka khona.
I-Ethernet
Umzekelo we-BUS protocol ziiprothokholi ze-Ethernet.I-Ethernet yenza utshintshiselwano lwedatha ngendlela yeepakethi zedatha nazo zonke izixhobo kwinethiwekhi.Unxibelelwano lwexesha lokwenyani lwenzeka kumanqanaba amathathu onxibelelwano.Eli linqanaba lolawulo kunye nenqanaba le-sensor / actuator.Ngenxa yale njongo, imigangatho efanayo yenziwa.Ezi zilawulwa liZiko lobuNjineli boMbane kunye nobuNjineli boMbane (IEEE).
Njani Fieldbus kunye Ethernet Thelekisa
I-Ethernet yenza ukuhanjiswa kwedatha ngexesha langempela kunye nokuhanjiswa kweemali ezinkulu zedatha.Ngeebhasi ezihamba phambili, oku akunakwenzeka okanye kunzima kakhulu.Kukwakho nendawo enkulu yeedilesi enenani eliphantse langenamda labathathi-nxaxheba.
Imidiya yokuhanjiswa kwe-Ethernet
Imidiya eyahlukeneyo yothumelo inokwenzeka ukuhanjiswa kweeprotocol ze-Ethernet.Ezi zinokuba ngumsakazo, i-fiber optic okanye imigca yobhedu, umzekelo.Ikhebula lobhedu lifumaneka rhoqo kunxibelelwano lwezoshishino.Ukwahlula kwenziwa phakathi kweendidi zemigca emi-5.Ukwahlula kwenziwa apha phakathi kwefrequency yokusebenza, ebonisa uluhlu lwamazaintambo, kunye nesantya sothumelo, esichaza umthamo wedatha kwiyunithi yexesha.
Ukuqukumbela
Ngamafutshane, sinokuthi aIBHASIyinkqubo yothumelo lwedatha phakathi kwabathathi-nxaxheba abaninzi ngendlela yothumelo eqhelekileyo.Kukho iinkqubo ezahlukeneyo ze-BUS kunxibelelwano lwamashishini, olunokuthi ludityaniswe nabavelisi.
Ngaba ufuna intambo yebhasi kwinkqubo yakho yeBHASI?Sineentambo ezihlangabezana neemfuno ezahlukeneyo, kubandakanywa i-radii yokugoba encinci, uhambo olude, kunye neendawo ezomileyo okanye ezinamafutha.
