Chii chinotanga kuuya mupfungwa paunofunga nezvezwi rokuti BUS?Pamwe ibhazi hombe, yeyero chizi kana hurongwa hwekufambisa neveruzhinji.Asi mumunda weinjiniya yemagetsi, izvi hazvina chekuita nemotokari.BUS chidimbu che "Binary Unit System".A "Binary Unit System" inoshandiswa kuendesa data pakati pevatori vechikamu mune network nerubatsiro rwecables.Mazuva ano, masisitimu eBUS akajairwa mukukurukurirana kwemaindasitiri, izvo zvisingambofungidzirwe pasina ivo.
Zvakatanga sei
Kukurukurirana kwemaindasitiri kwakatanga neparallel wiring.Vese vatori vechikamu mune network vaive newaya zvakananga kune yekutonga uye nhanho yekutonga.Nekuwedzera otomatiki, izvi zvaireva kuwedzera-kuwedzera wiring kuedza.Nhasi, kutaurirana kwemaindasitiri kunonyanya kuve kwakavakirwa pafieldbus masisitimu kana Ethernet-yakavakirwa kutaurirana network.
Fieldbus
"Midziyo yemumunda," senge ma sensors uye actuators, yakabatana kune programmable logic controller (inozivikanwa sePLC) kuburikidza newaya, serial mabhazi emumunda.Iyo fieldbus inovimbisa kukurumidza kuchinjana data.Mukupesana neyakafanana wiring, iyo fieldbus inongotaurirana chete netambo imwe.Izvi zvakanyanya kuderedza wiring kuedza.Bhazi remumunda rinoshanda maererano nenheyo yatenzi-muranda.Tenzi ane basa rekutonga maitiro uye muranda anogadzirisa mabasa akamirira.
MaFieldbuses anosiyana mune yavo topology, transmission protocol, kureba kwekutapurirana uye huwandu hwe data pateregiramu.Iyo network topology inotsanangura kurongeka chaiko kwemidziyo uye tambo.Musiyano unoitwa pano pakati pemuti topology, nyeredzi, tambo kana mhete topology.Mabhazi emumunda anozivikanwaProfibuskana CANopen.Iyo BUS protocol ndiyo seti yemitemo iyo kutaurirana kunoitika.
Ethernet
Muenzaniso weBUS protocol ndeye Ethernet protocol.Ethernet inogonesa kuchinjana kwedata muchimiro chemapaketi edata ane ese maturusi munetiweki.Kukurukurirana kwenguva chaiyo kunoitika mumatanho matatu ekutaurirana.Iyi ndiyo nhanho yekudzora uye sensor / actuator level.Nechinangwa ichi, zviyero zvakafanana zvinogadzirwa.Izvi zvinotungamirirwa neInstitute of Electrical and Electronics Engineering (IEEE).
Sei Fieldbus uye Ethernet Enzanisa
Ethernet inogonesa chaiyo-nguva yekufambisa data uye kutapurirana kwehuwandu hukuru hwe data.Nemabhazi emumunda emhando yepamusoro, izvi hazvigoneke kana kuoma zvakanyanya.Kune zvakare nzvimbo yakakura yekero ine nhamba isingaverengeki yevatori vechikamu.
Ethernet kutapurirana midhiya
Yakasiyana-siyana yekufambisa midhiya inogoneka pakufambisa kweEthernet protocol.Izvi zvinogona kuva redhiyo, fiber optic kana mitsara yemhangura, somuenzaniso.Tambo yemhangura inonyanya kuwanikwa mukukurukurirana kwemaindasitiri.Musiyano unoitwa pakati pezvikamu zvishanu-mutsara.Musiyano unoitwa pano pakati peiyo frequency yekushandisa, iyo inoratidza kuwanda kweiyocable, uye chiyero chekutumira, chinotsanangura huwandu hwe data pachikamu chenguva.
Mhedziso
Muchidimbu, tinogona kuti aBUSihurongwa hwekufambiswa kwedata pakati pevazhinji vatori vechikamu kuburikidza neyakajairwa nzira yekufambisa.Kune akasiyana maBUS masisitimu mukutaurirana kwemaindasitiri, ayo anogona zvakare kubatanidzwa kune vanogadzira.
Unoda tambo yebhazi kune yako BUS system?Tine tambo dzinosangana zvakasiyana-siyana zvinodiwa, zvinosanganisira diki bending radii, nzendo refu, uye yakaoma kana ine mafuta nharaunda.
