Ntho ea pele e tlang kelellong ke efe ha u nahana ka lentsoe BUS?Mohlomong bese e kholo, e tšehla ea chisi kapa lipalangoang tsa lehae tsa hau.Empa tšimong ea boenjiniere ba motlakase, sena ha se amane le koloi.BUS ke khutsufatso ea "Binary Unit System"."Binary Unit System" e sebelisetsoa ho fetisetsa data pakeng tsa barupeluoa marang-rang ka thuso ealikhoele.Matsatsing ana, litsamaiso tsa BUS li tloaelehile puisanong ea indasteri, eo ho seng bonolo ho e nahana ntle le bona.
Kamoo e qalileng kateng
Puisano ea indasteri e qalile ka lithapo tse tšoanang.Barupeluoa bohle ba marang-rang ba ne ba kenyelelitsoe ka ho toba boemong ba taolo le taolo.Ka ho eketseha ha li-automation, sena se ne se bolela boiteko bo ntseng bo eketseha ba ho kopanya lithapo.Kajeno, puisano ea indasteri e itšetlehile haholo ka mekhoa ea li-fieldbus kapa marang-rang a puisano a thehiloeng ho Ethernet.
Fieldbus
"Lisebelisoa tsa masimo," tse kang li-sensor le li-actuator, li hokahane le "programmable logic controller" (e tsejoang e le PLC) ka li-fieldbus tse nang le marang-rang.The fieldbus e netefatsa phapanyetsano ea data ka potlako.Ho fapana le wiring e ts'oanang, fieldbus e buisana feela ka mohala o le mong.Sena se fokotsa haholo ts'ebetso ea wiring.Fieldbus e sebetsa ho latela molao-motheo oa master-lekhoba.Mong'a ke eena ea ikarabellang bakeng sa ho laola lits'ebetso mme lekhoba le sebetsana le mesebetsi e emetseng.
Li-Fieldbus li fapana ho ea ka topology ea tsona, liprothokholo tsa phetiso, bolelele ba phetisetso le boholo ba data ka thelekramo.Topology ea marang-rang e hlalosa tlhophiso e khethehileng ea lisebelisoa le likhoele.Phapano e etsoa mona pakeng tsa topology ea lifate, naleli, cable kapa ring topology.Tse tsebahalang fieldbuses keProfibuskapa CANopen.Protocol ea BUS ke sete ea melao eo puisano e etsahalang tlas'a eona.
Ethernet
Mohlala oa liprothokholo tsa BUS ke li-protocol tsa Ethernet.Ethernet e nolofalletsa phapanyetsano ea data ka mokhoa oa lipakete tsa data tse nang le lisebelisoa tsohle marang-rang.Puisano ea nako ea sebele e etsahala maemong a mararo a puisano.Ena ke boemo ba taolo le boemo ba sensor / actuator.Bakeng sa morero ona, ho etsoa litekanyetso tse tšoanang.Tsena li laoloa ke Institute of Electrical and Electronics Engineering (IEEE).
Kamoo Fieldbus le Ethernet Bapisa
Ethernet e thusa phetiso ea data ea nako ea nnete le phetiso ea bongata bo boholo ba data.Ka li-fieldbus tsa khale, sena ha se khonehe kapa se thata haholo.Ho boetse ho na le aterese e kholoanyane e nang le palo e batlang e se na moeli ea bankakarolo.
Mecha ea phatlalatso ea Ethernet
Mecha e fapaneng ea phetisetso e ka khoneha bakeng sa phetiso ea liprothokholo tsa Ethernet.Tsena e ka ba li-radio, fiber optic kapa mela ea koporo, mohlala.Mohala oa koporo o fumanoa hangata puisanong ea indasteri.Phapano e etsoa lipakeng tsa mekhahlelo e mehlano.Phapano e etsoa mona pakeng tsa maqhubu a ts'ebetso, a bonts'ang lebelo la maqhubu athapo, le sekhahla sa phetisetso, se hlalosang bophahamo ba data ka yuniti ea nako.
Qetello
Ka kakaretso, re ka re aBESEke sistimi ea phetiso ea data lipakeng tsa barupeluoa ba 'maloa ka tsela e tloaelehileng ea phetiso.Ho na le litsamaiso tse fapaneng tsa BUS puisanong ea indasteri, e ka hokahanngoang le bahlahisi.
A na u hloka thapo ea bese bakeng sa sistimi ea hau ea BUS?Re na le likhoele tse fihlelang litlhoko tse fapaneng, ho kenyelletsa le radii e nyane e kobehang, maeto a malelele, le libaka tse omeletseng kapa tse mafura.
