He aha ka BUS e kū ai?

He aha ka mea mua e hiki mai ana i kou noʻonoʻo ʻana i ka huaʻōlelo BUS?Malia paha ʻo ka pahi kaʻa nui melemele a i ʻole kāu ʻōnaehana kaʻa lehulehu.Akā ma ke kahua o ka ʻenekinia uila, ʻaʻohe mea pili i ke kaʻa.ʻO BUS kahi acronym no "Binary Unit System".Hoʻohana ʻia kahi "Binary Unit System" e hoʻoili i ka ʻikepili ma waena o nā mea komo i kahi pūnaewele me ke kōkua ouwea.I kēia mau lā, maʻamau nā ʻōnaehana BUS i ka kamaʻilio ʻoihana, hiki ʻole ke noʻonoʻo ʻia me ka ʻole o lākou.

Pehea i hoʻomaka ai

Ua hoʻomaka ke kamaʻilio ʻenehana me nā uwila parallel.Ua hoʻopili pololei ʻia nā mea komo a pau i kahi pūnaewele i ka pae hoʻomalu a me ka hoʻoponopono.Me ka hoʻonui ʻana i ka automation, ʻo ia ka mea e hoʻonui mau ana i ka hoʻoikaika uea.I kēia mau lā, hoʻokumu nui ʻia ka kamaʻilio ʻoihana ma nā ʻōnaehana fieldbus a i ʻole nā ​​​​ʻenehana kamaʻilio pili Ethernet.

Bus kahua

Hoʻopili ʻia nā "mea hana kahua," e like me nā mea ʻike a me nā mea hana, i kahi mea hoʻoponopono logic programmable (ʻike ʻia ʻo PLC) ma o nā uea, serial fieldbuses.Mālama ka fieldbus i ka hoʻololi ʻikepili wikiwiki.ʻOkoʻa me ka wili like, kamaʻilio ka fieldbus ma o ke kaula hoʻokahi.Hoemi nui keia i ka hana uwea.Hana ʻia kahi kahua pahi e like me ke kumu kumu-kauā.Na ka haku ke kuleana no ka mālama ʻana i nā kaʻina hana a me ke kauā i nā hana e kali nei.

ʻOkoʻa nā fieldbuses i kā lākou topology, nā protocol transmission, ka lōʻihi o ka hoʻouna ʻana a me ka nui o ka ʻikepili no ke kelepona.Hōʻike ka topology pūnaewele i ka hoʻonohonoho kikoʻī o nā mea hana a me nā kaula.Hoʻokaʻawale ʻia ma waena o ka topology lāʻau, ka hōkū, ke kaula a i ʻole ka topology ring.ʻO nā buses i ʻike ʻiaProfibusa i ʻole CANopen.ʻO ka protocol BUS ka hoʻonohonoho o nā lula ma lalo o ke kamaʻilio ʻana.

Ethernet

ʻO kahi hiʻohiʻona o nā protocol BUS nā protocol Ethernet.Hiki i ka Ethernet ke hoʻololi i ka ʻikepili ma ke ʻano o nā ʻeke ʻikepili me nā mea hana a pau i kahi pūnaewele.Loaʻa ka kamaʻilio manawa maoli i ʻekolu pae kamaʻilio.ʻO kēia ka pae mana a me ka pae sensor/actuator.No kēia kumu, ua hana ʻia nā kūlana kūlike.Mālama ʻia kēia mau mea e ka Institute of Electrical and Electronics Engineering (IEEE).

Pehea e hoʻohālikelike ai ʻo Fieldbus a me Ethernet

Hāʻawi ʻo Ethernet i ka lawe ʻana i ka ʻikepili i ka manawa maoli a me ka hoʻouna ʻana i ka nui o ka ʻikepili.Me nā kahua mokulele maʻamau, ʻaʻole hiki a paʻakikī paha kēia.Aia kekahi wahi ʻōlelo nui aʻe me ka helu palena ʻole o nā mea komo.

Media hoʻouna Ethernet

Hiki i nā ʻano media hoʻoili like ʻole no ka hoʻouna ʻana i nā protocol Ethernet.Hiki iā ia ke radio, fiber optic a i ʻole laina keleawe, no ka laʻana.Loaʻa pinepine ʻia ke kaula keleawe ma ke kamaʻilio ʻoihana.Hoʻokaʻawale ʻia ma waena o nā ʻano laina 5.Hana ʻia kahi ʻokoʻa ma waena o ke alapine hana, e hōʻike ana i ka laulā alapine o kauwea, a me ka helu hoʻouna, e wehewehe ana i ka nui o ka ʻikepili i kēlā me kēia ʻāpana o ka manawa.

Ka hopena

I ka hōʻuluʻulu ʻana, hiki iā mākou ke ʻōlelo aBUShe ʻōnaehana no ka lawe ʻana i ka ʻikepili ma waena o kekahi mau mea komo ma ke ala hoʻouna maʻamau.Aia nā ʻōnaehana BUS like ʻole i ka kamaʻilio ʻoihana, hiki ke hoʻopili ʻia i nā mea hana.

Pono ʻoe i ke kaula kaʻa no kāu ʻōnaehana BUS?Loaʻa iā mākou nā kaula e hoʻokō i nā koi like ʻole, me nā radii piko liʻiliʻi, nā huakaʻi lōʻihi, a me nā wahi maloʻo a ʻaila paha.
