Dab tsi yog kev lag luam Automation? Nyob rau hauv cov lus cog tseg, kev lag luam automer yog hais txog cov txheej txheem ntawm kev qhia ntau yam cuab yeej thoob plaws txhua theem ntawm kev tsim khoom ntawm kev ua haujlwm pub dawb. Tseem ceeb tshaj, nws ua kom nrawm dua thiab ua tiav kev ua haujlwm nrawm dua, yog li tag nrho cov txheej txheem yog termed kev lag luam kev txhim kho. Tam sim no, hla kev lag luam xws li roj av, tshuaj, kev tsim kho tsheb, kev txhim kho, kev txhim kho hauv kev txhim kho hauv kev tswj hwm thev naus laus zis tshuab. Niaj hnub no, peb tshawb nrhiav lub xeev tam sim no thiab yav tom ntej ntawm kev lag luam automation tswj.
Tam Sim No Lub Xeev Kev Muaj Automation Control
Muaj Automation encompasses peb Cheebtsam: Muaj cov tshuab siv roj av, cov khoom siv kho vajtse, thiab software. Nws yog cov thev naus laus zis ua haujlwm, tswj cov kev tshawb fawb, thiab kev ua tiav cov hom phiaj ua haujlwm raws li kev tsim khoom lag luam raws li kev tsim khoom lag luam, txo qis, thiab txhim kho kom zoo dua.
Kev nce qib hauv cov khoom siv hluav taws xob hauv cov khoom siv hluav taws xob thiab kev sib txuas lus, kev niaj hnub muaj cov automation tswj hwm feem ntau ntawm cov microcomputer - raws cov tshuab. Tam sim no cov tswj hwm tam sim no ib tug peb-}} Cov kev tswj hwm qib, thiab cov neeg ua haujlwm ua. Kev tswj cov tshuab ua haujlwm feem ntau siv cov tshuab tswj cov cav txuas ntxiv (DCS), faib cov chaw tswj hwm (DCS), thiab cov khoom siv tswj hwm pod
Ua ntej, Programmable maub los (PLC) thev naus laus zis sawv cev rau ib tiam tshiab ntawm kev tswj hwm kev lag luam raws li khoos phis tawj. Nws yog lub tshuab hluav taws xob siv hluav taws xob tshwj xeeb yog tsim rau cov chaw muaj kev lag luam ua cov kev sib lwv, ua ntu zus, suav, sijhawm ua haujlwm. Plcs ua tau zoo rau tag nrho cov txheej txheem tsim khoom ntawm cov khoom lag luam thiab machinery, tswj kav}}} lo lus lag luam dominance nyob rau hauv kev muaj tshuab automation.
Thib ob, faib cov tshuab tswj khoom (DCS) tau ua rau kev sib txuas lus sib txuas lus thiab muaj ntau {{} theem qib kev kos duab, nrog rau cov txheej txheem kev tshuaj xyuas thiab tswj cov qib. DCS kev sib xyaw ua ke cov thev naus laus zis siab dua- kev sib txuas lus, thiab ua rau nws cov khoom lag luam ntawm cov khoom siv tshuab ntau}}}}}}}} technology convergence.
Qhov thib peb, nrog cov ntaub ntawv thev naus laus zis thev naus laus zis, kev tswj hwm PC tau ua ke, thiab cov cuab yeej tswj hwm niaj hnub thiab cov cuab yeej siv thev naus laus zis. Qhov no ua raws li cov kev siv thev naus laus zis tshiab rau cov ntaub ntawv, digitalization, thiab kev txawj ntse. Txij li thaum nkag mus rau kev siv tub rog hauv lub xyoo 1990, cov PC tau nthuav dav rau hauv kev lag luam thiab pej xeem cov ntawv, ua tiav cov ntawv thov dav dav.
PLCS hloov zuj zus mus rau kev sib koom ua ke thiab sib txuas
Cov lus qhia ntawm cov maub los sib xyaw (OCS) tau qhia meej txog txoj kev mus rau PLC kev sib koom ua ke. Thaum hloov zuj zus los ntawm PLCS, OCS tsis yog tsuas yog plC. Nws koom ua ke Plycs nrog HMIS, I / O, thiab nrawm nrawm nrawm siv thev naus laus zis, koom nrog kev siv tshuab hluav taws xob. Ob qho Plc cov kev pabcuam thiab HMI cov kev siv HMI siv lub cajmeem ua haujlwm tsim los ntawm Horner. Nws cov haujlwm yooj yim thiab cov haujlwm tau zoo tau ua rau nws zoo siab heev los ntawm cov neeg siv, ua cov qauv rau PLC kev sib raug zoo nce. Tsis tas li ntawd, kev nrhav hauv Internet technology tau tsav hloov pauv hauv kev tswj cov txheej txheem los ntawm kev nthuav dav ntawm Ethernet Technology. Tam sim no txoj kev txhim kho kev txhim kho ntawm kev txhim kho hauv internet los hloov zuj zus mus rau kev sib tham. Nrog siab - ceev cov ntaub ntawv xa mus rau cov tshuab sib txuas lus thiab kev sib koom ua ke plcs yuav txuas ntxiv nce qib kev daws teeb meem.
Kev Loj Hlob Ntawm Cov Ntawv Xov Xwm Tshiab Tswj Tshuab
Tsav los ntawm cov thev naus laus zis tshiab, tswj lub cav hluav taws xob ua ke tswj hwm cov tshuab hluav taws xob, thiab faib cov tshuab tswj khoom siv hluav taws xob (DCS). Niaj hnub no, lawv tau nthuav dav thiab txuas ntxiv mus rau teb daim teb tswj (FCS). Lub neej tom ntej yuav muaj kev sib zog ua kom muaj zog, feem ntau vim tias FCS sib xyaw ua ke thev naus laus zis tshiab xws li DCS, Kev Tswj Ethernet, thiab kev tswj hwm qib siab. Muaj Ethernet Etherneties muab cov tswv yim Ethernicies muab cov kev ntseeg txhim khu kev qha, hloov tau, thiab cov ntaub ntawv xa tawm cov ntaub ntawv sib kis, ua rau cov kev thov dav dav ntawm FCS hauv kev muaj chaw nyob. Cov teb tshiab tswj cov tshuab yuav tswj kev loj hlob hauv lub chaw tswj hwm thiab nyob ib txoj haujlwm tseem ceeb dua.
Kev txhim kho ntawm kev tswj hwm ntse
Qhov kev tawm ntawm cov ntse tswj tau raug hloov pauv nyob thoob plaws ntau daim teb. Raws li ib daim ntawv thov ntawm cov ntaub ntawv thev naus laus zis, nws ua haujlwm rau kev txawj ntse artificial ntse, thiab cov txuj ci siab kom muab cov khoom siv rau simulate cov yam ntxwv thiab ua haujlwm ntawm tib neeg kev txawj ntse. Muaj cov ntsiab lus ntse, tsim los ntawm kev txawj ntse intification, tshwm sim feem ntau hauv cov khoom siv kho tshuab cov tshuab. Nws paub qhib cov tshuab xa xov ntse los ntawm Ethernet thiab Web Technologies, faib cov qauv txheej txheem, faib, thiab rov siv dua kev lag luam kev daws teeb meem. Piv txwv li: tshiab {{{{5 5}}} transmitters cov khoom thiab cov transmittters thiab ntse precision, thiab kev txawj ntse. Smart Valve qhov thaiv, tswj tau los ntawm kev sib koom ua ke microcontrollers, cia kev teeb tsa ntawm txhua qhov tsis tswj hwm. Lawv pab cov yam ntxwv kho cov xeeb ceem xws li linear, cais {{9} muaj feem pua tswj, sib luag- qhib, thaum ua tiav cov haujlwm ntse. Cov embedding ntawm cov network ua kom paub tseeb ntawm kev txawj ntse ib qho kev tsis sib xws.
