Iyiphi into yokuqala efikayo engqondweni yakho uma ucabanga ngegama elithi IBHASI?Mhlawumbe ibhasi likashizi elikhulu, eliphuzi noma isistimu yangakini yezokuthutha zomphakathi.Kodwa emkhakheni wobunjiniyela bukagesi, lokhu akuhlangene nemoto.IBHASI isifinyezo se-“Binary Unit System”.I-"Binary Unit System" isetshenziselwa ukudlulisa idatha phakathi kwabahlanganyeli kunethiwekhi ngosizo lweizintambo.Kulezi zinsuku, amasistimu e-BUS ajwayelekile ekuxhumaneni kwezimboni, okungenakucatshangwa ngaphandle kwawo.
Kwaqala kanjani konke
Ukuxhumana kwezimboni kuqale ngezintambo ezihambisanayo.Bonke ababambiqhaza kunethiwekhi babexhunywe izintambo ngokuqondile ezingeni lokulawula nelokulawula.Ngokukhula kwe-automation, lokhu bekusho umzamo olokhu ukhula wezintambo.Namuhla, ukuxhumana kwezimboni kusekelwe kakhulu ezinhlelweni zamabhasi noma amanethiwekhi okuxhumana asekelwe ku-Ethernet.
I-Fieldbus
“Izisetshenziswa zasenkambu,” njengezinzwa nama-actuator, zixhunywe kusilawuli se-logicable esihlelekayo (esaziwa ngokuthi i-PLC) ngamabhasi ahamba ngentambo, alandelanayo.I-fieldbus iqinisekisa ukushintshaniswa kwedatha okusheshayo.Ngokungafani nezintambo ezihambisanayo, i-fieldbus ixhumana kuphela ngentambo eyodwa.Lokhu kunciphisa kakhulu umzamo wokufaka izintambo.I-fieldbus isebenza ngokomgomo we-master-slave.Umphathi unesibopho sokulawula izinqubo futhi isigqila sicubungula imisebenzi elindile.
Ama-Fieldbus ayahluka nge-topology yawo, izimiso zokudlulisela, ubude bokudlulisa okuphezulu kanye nenani eliphakeme ledatha ngetelegramu ngayinye.I-topology yenethiwekhi ichaza ukuhlelwa okuthile kwamadivayisi namakhebuli.Umehluko wenziwa lapha phakathi kwe-topology yesihlahla, inkanyezi, ikhebula noma i-ring topology.Ama-fieldbuses aziwayoProfibusnoma i-CANopen.Iphrothokholi yeBHASI isethi yemithetho ukuxhumana okwenzeka ngaphansi kwayo.
I-Ethernet
Isibonelo samaphrothokholi e-BUS amaphrothokholi e-Ethernet.I-Ethernet inika amandla ukushintshana kwedatha ngendlela yamaphakethe edatha anawo wonke amadivayisi akunethiwekhi.Ukuxhumana ngesikhathi sangempela kwenzeka emazingeni amathathu okuxhumana.Leli izinga lokulawula kanye neleveli yenzwa/ye-actuator.Ngale njongo, kwakhiwa izindinganiso ezifanayo.Lezi ziphethwe yi-Institute of Electrical and Electronics Engineering (IEEE).
Ukuqhathanisa kanjani i-Fieldbus ne-Ethernet
I-Ethernet inika amandla ukudluliswa kwedatha yesikhathi sangempela kanye nokudluliselwa kwenani elikhulu ledatha.Ngamabhasi asendulo, lokhu akunakwenzeka noma kunzima kakhulu.Kukhona nendawo yamakheli enkudlwana enenani cishe elingenamkhawulo labahlanganyeli.
Imidiya yokudlulisa i-Ethernet
Imidiya ehlukene yokudlulisa iyakwazi ukudluliswa kwezivumelwano ze-Ethernet.Lezi kungaba umsakazo, i-fiber optic noma imigqa yethusi, isibonelo.Ikhebula lethusi livame ukutholakala ekuxhumaneni kwezimboni.Umehluko wenziwa phakathi kwezigaba zemigqa emi-5.Umehluko wenziwa lapha phakathi kwefrikhwensi yokusebenza, ekhombisa ububanzi befrikhwensi yeikhebula, kanye nezinga lokudlulisela, elichaza umthamo wedatha ngeyunithi ngayinye yesikhathi.
Isiphetho
Kafushane, singasho ukuthi aIBHASIiwuhlelo lokudluliswa kwedatha phakathi kwabahlanganyeli abambalwa ngendlela evamile yokudlulisela.Kunezinhlelo ezahlukene zamaBHASI ekuxhumaneni kwezimboni, ezingabuye zixhunywe kubakhiqizi.
Ingabe udinga intambo yebhasi yohlelo lwakho lweBHASI?Sinezintambo ezihlangabezana nezidingo ezihlukahlukene, okuhlanganisa irediya encane yokugoba, uhambo olude, nezindawo ezomile noma ezinamafutha.
