Kodi chinthu choyamba chomwe chimabwera m'maganizo ndi chiyani mukaganizira mawu akuti BUS?Mwinanso basi yayikulu, yachikasu kapena zoyendera zapagulu lanu.Koma pankhani ya uinjiniya wamagetsi, izi sizikugwirizana ndi galimoto.BUS ndi chidule cha "Binary Unit System"."Binary Unit System" imagwiritsidwa ntchito kusamutsa deta pakati pa omwe akutenga nawo mbali pa intaneti mothandizidwa ndizingwe.Masiku ano, machitidwe a BUS ndi omwe amalumikizana ndi mafakitale, zomwe sizingaganizidwe popanda iwo.
Momwe zidayambira
Kulumikizana kwa mafakitale kunayamba ndi waya wofanana.Onse omwe adatenga nawo gawo pa netiweki adalumikizidwa mwachindunji kumlingo wowongolera ndi kuwongolera.Ndi kuchulukirachulukira kwa makina, izi zikutanthauza kuyesetsa kokulirapo kwa waya.Masiku ano, kulumikizana kwa mafakitale kumakhazikika pamakina a fieldbus kapena ma Ethernet-based communication network.
Fieldbus
"Zida zam'munda," monga masensa ndi ma actuators, zimalumikizidwa ndi chowongolera (chodziwika kuti PLC) pogwiritsa ntchito ma waya, ma serial fieldbus.Fieldbus imatsimikizira kusinthana kwa data mwachangu.Mosiyana ndi mawaya ofanana, fieldbus imangolankhula kudzera pa chingwe chimodzi.Izi zimachepetsa kwambiri ntchito ya wiring.Fieldbus imagwira ntchito molingana ndi mfundo ya mbuye-kapolo.Mbuyeyo ali ndi udindo woyang'anira ndondomeko ndi kapolo amayendetsa ntchito zomwe zikuyembekezera.
Ma Fieldbus amasiyana mu topology yawo, njira zotumizira, kutalika kopitilira muyeso komanso kuchuluka kwa data pa telegalamu.Network topology imafotokoza makonzedwe enieni a zida ndi zingwe.Kusiyanitsa kumapangidwa apa pakati pa mitengo yamtengo wapatali, nyenyezi, chingwe kapena ring topology.Ma fieldbus odziwika ndiProfibuskapena CANopen.Ndondomeko ya BUS ndi ndondomeko ya malamulo omwe kuyankhulana kumachitika.
Efaneti
Chitsanzo cha ma protocol a BUS ndi ma protocol a Ethernet.Ethernet imathandizira kusinthana kwa data ngati mapaketi a data okhala ndi zida zonse pamaneti.Kulankhulana kwenikweni kumachitika mu magawo atatu olankhulana.Uwu ndiye mulingo wowongolera ndi mulingo wa sensor / actuator.Pachifukwa ichi, miyezo yofananira imapangidwa.Izi zimayendetsedwa ndi Institute of Electrical and Electronics Engineering (IEEE).
Momwe Fieldbus ndi Efaneti Fananizani
Ethernet imathandizira kutumiza kwa data munthawi yeniyeni ndikutumiza kwa data yochulukirapo.Ndi ma fieldbus apamwamba, izi sizingatheke kapena zovuta kwambiri.Palinso maadiresi okulirapo omwe ali ndi chiwerengero chosawerengeka cha otenga nawo mbali.
Ethernet kufalitsa media
Mitundu yosiyanasiyana yotumizira ndi yotheka kufalitsa ma protocol a Ethernet.Izi zitha kukhala wailesi, fiber optic kapena mizere yamkuwa, mwachitsanzo.Chingwe chamkuwa chimapezeka kawirikawiri mukulankhulana kwa mafakitale.Kusiyanitsa kumapangidwa pakati pa magulu a mizere 5.Kusiyanitsa kumapangidwa apa pakati pa ma frequency opangira, omwe akuwonetsa kuchuluka kwa ma frequency achingwe, ndi mlingo wotumizira, womwe umalongosola kuchuluka kwa deta pa nthawi imodzi.
Mapeto
Mwachidule tinganene kuti aBASIndi njira yotumizira deta pakati pa otenga nawo mbali angapo kudzera panjira wamba.Pali machitidwe osiyanasiyana a BUS mukulankhulana kwa mafakitale, omwe amathanso kulumikizidwa ndi opanga.
Kodi mukufuna chingwe cha basi panjira yanu ya BUS?Tili ndi zingwe zomwe zimakwaniritsa zofunikira zosiyanasiyana, kuphatikiza ma radii ang'onoang'ono opindika, maulendo ataliatali, ndi malo owuma kapena opaka mafuta.
