BUS igereranya iki?

Niki kintu cya mbere kiza mubitekerezo iyo utekereje ijambo BUS?Birashoboka bisi nini, umuhondo wa bisi cyangwa sisitemu yo gutwara abantu.Ariko mubijyanye nubuhanga bwamashanyarazi, ibi ntaho bihuriye nimodoka.BUS ni amagambo ahinnye ya “Binary Unit Sisitemu”.“Binary Unit Sisitemu” ikoreshwa mu kohereza amakuru hagati y'abitabiriye umuyoboro ubifashijwemo nainsinga.Muri iki gihe, sisitemu ya BUS isanzwe mu itumanaho ry’inganda, ku buryo bidashoboka ko umuntu yatekereza atayifite.

Ukuntu byose byatangiye

Itumanaho ryinganda ryatangiranye nu nsinga zibangikanye.Abitabiriye umuyoboro bose bashizwe kumurongo wo kugenzura no kugenzura.Hamwe no kwiyongera kwikora, ibi bivuze imbaraga zo kwagura imbaraga.Muri iki gihe, itumanaho mu nganda ahanini rishingiye kuri sisitemu yo mu murima cyangwa imiyoboro y'itumanaho ishingiye kuri Ethernet.

Ikibuga

"Ibikoresho byo mu murima," nka sensor na actuator, bihujwe na progaramu ya logique igenzurwa na porogaramu (izwi nka PLC) ikoresheje insinga, serial ikibuga.Fieldbus itanga amakuru yihuse.Bitandukanye no guhuza insinga, ikibuga cyitumanaho kivuga gusa umugozi umwe.Ibi bigabanya cyane imbaraga zo gukoresha.A fieldbus ikora ikurikije ihame rya shebuja-imbata.Shebuja ashinzwe kugenzura inzira kandi imbata itunganya imirimo itegereje.

Fieldbus ziratandukanye muri topologiya, protocole yoherejwe, uburebure ntarengwa bwoherejwe hamwe namakuru menshi kuri telegaramu.Urusobe topologiya isobanura gahunda yihariye yibikoresho ninsinga.Itandukaniro rikorwa hano hagati yibiti topologiya, inyenyeri, umugozi cyangwa impeta ya topologiya.Ibibuga bizwi niProfibuscyangwa CANopen.Porotokole ya BUS ni amategeko agenga itumanaho.

Ethernet

Urugero rwa BUS protocole ni Ethernet protocole.Ethernet ituma guhanahana amakuru muburyo bwa paki yamakuru hamwe nibikoresho byose murusobe.Itumanaho nyaryo riba mubyiciro bitatu byitumanaho.Uru nurwego rwo kugenzura hamwe na sensor / urwego rukora.Kubwiyi ntego, hashyizweho ibipimo bimwe.Ibi bicungwa n'Ikigo gishinzwe amashanyarazi na Electronics Engineering (IEEE).

Nigute Fieldbus na Ethernet Bagereranya

Ethernet itanga amakuru nyayo yohereza no kohereza amakuru menshi.Hamwe na bisi ya classique, ibi ntibishoboka cyangwa biragoye cyane.Hariho kandi umwanya munini wa adresse hamwe numubare utagira imipaka wabitabiriye.

Itumanaho rya Ethernet

Ibitangazamakuru bitandukanye byohereza birashoboka kohereza porotokole ya Ethernet.Ibi birashobora kuba radio, fibre optique cyangwa imirongo yumuringa, kurugero.Umugozi wumuringa uboneka cyane mubitumanaho byinganda.Itandukaniro rikorwa hagati yimirongo 5.Itandukanyirizo rikorwa hano hagati yimikorere ikora, yerekana intera yumurongo waumugozi, nigipimo cyo kohereza, gisobanura ingano yamakuru kuri buri gice cyigihe.

Umwanzuro

Muri make, dushobora kuvuga ko aBUSni sisitemu yo kohereza amakuru hagati yabitabiriye benshi binyuze munzira rusange.Hariho sisitemu zitandukanye za BUS mu itumanaho ryinganda, zishobora no guhuzwa nababikora.

Ukeneye umugozi wa bisi ya sisitemu ya BUS?Dufite insinga zujuje ibisabwa bitandukanye, harimo radiyo ntoya igoramye, ingendo ndende, hamwe n'ibidukikije byumye cyangwa amavuta.
