Dab tsi yog qhov muaj pes tsawg leeg ntawm industrial computer field bus system? Muaj pes tsawg feem?
Industrial computer field bus system (FCS), uas yog siv nyob rau hauv lub teb ntau lawm thiab paub ob-txoj kev serial digital kev sib txuas lus ntawm computerized ntsuas thiab tswj cov cuab yeej, kuj hu ua lub hauv qab tswj network ntawm qhib, digital thiab multi-point kev sib txuas lus. Nws yog dav siv nyob rau hauv automation systems nyob rau hauv manufacturing, txheej txheem industries, tsev, tsheb thauj mus los thiab lwm yam teb. I-controller field bus system feem ntau yog tsim los ntawm peb qhov chaw: txheej txheej txheej txheej txheem, txheej txheej txheej txheem saib xyuas thiab txheej txheej tswj cov ntaub ntawv.
Cov txheej txheem teb yog siv rau saum txheej txheej ntawm tag nrho cov kab ke, thiab nws lub luag haujlwm tseem ceeb yog txhawm rau txuas cov khoom siv hauv teb, xws li faib I / O, sensors, tsav tsheb, actuators, switchgear, thiab lwm yam. khoom siv thiab khoom siv. Tus tswv chaw nres tsheb (PLC, PC, thiab lwm yam) yog lub luag haujlwm rau kev tswj xyuas kev sib txuas lus hauv tsheb npav thiab txhua qhov chaw nres tsheb sib txuas lus qhev.
Cov txheej txheem saib xyuas cov txheej txheem nyob rau hauv nruab nrab txheej ntawm cov txheej txheem tswj, thiab muaj kev ua haujlwm console computer, console computer lossis PLC ntxiv rau daim npav Ethernet los tsim ib qho kev lag luam Ethernet. Kev sib kis ceev ntawm cov txheej txheem kev soj ntsuam cov txheej txheem tsis yog qhov tseem ceeb tshaj plaws, qhov tseem ceeb tshaj plaws yog kom xa tau cov ntaub ntawv ntau, thiab kev sib txuas lus yog txiav txim siab thiab rov ua dua nyob rau hauv cov ntaub ntawv ntawm kev xav tau ntawm lub sijhawm tiag tiag.
Cov txheej txheem tswj cov ntaub ntawv yog nyob rau sab saum toj txheej ntawm kev tswj hwm thiab lees txais TCP / IP raws tu qauv. Cov khoom siv uas tuaj yeem txuas nrog cov ntaub ntawv txheej suav nrog cov tswj hwm, PCs, chaw nres tsheb tus neeg teb xov tooj, kev kub ceev I / O, lwm yam khoom siv hauv cheeb tsam hauv zos, thiab cov khoom siv rooj vag. Nkag mus rau hauv Internet. Cov yam ntxwv tseem ceeb ntawm kev sib txuas lus ntawm cov txheej txheem tswj cov ntaub ntawv yog qhov ntau ntawm cov ntaub ntawv kev sib txuas lus yog qhov loj, qhov tshwm sim ntawm kev sib txuas lus yog qhov tseem ceeb, kev txhawb nqa kev sib txuas ceev yog qhov yuav tsum tau muaj, thiab cov kev xav tau ntawm lub sijhawm tiag tiag tsis siab.
