Muaj cov maub los siv nyob rau hauv ntau cov kev siv hluav taws xob niaj hnub, xws li DCS systems rau interface nrog cov tshuab lag luam uas cov txheej txheem ntau lawm tuaj yeem cuam tshuam ntawm kev lag luam. DCS cov tshuab feem ntau siv hauv cov chaw tswj cov khoom xws li cov roj ua kom cov roj, pov tseg cov nroj tsuag thiab cov khoom siv tshuaj lom neeg. Kab lus no tsom rau cov qauv theem pib thiab hom kev muaj txuj ci tshuab hluav taws xob.
1, faib cov txheej txheem tswj (DCS)
Muaj Cov Hluav Taws Xob DCS siv lub chaw soj ntsuam hauv paus rau kev koom tes tswj hwm hauv zos kom ua tag nrho cov txheej txheem ntau lawm. Los ntawm kev coj ua cov kab ke ntau lawm, DCS txo qhov cuam tshuam ntawm tus neeg ua tsis tiav ntawm tag nrho cov kab ke. Hauv ntau lub tshuab niaj hnub, DCS system thiab kev tsim lub tshuab teeb tsa teeb tsa kev cuam tshuam nruab nrab ntawm thiaj li hais tias cov txheej txheem ntau lawm ntawm kev lag luam.
2, Cov ntaub ntawv tau txais thiab soj ntsuam cov kab ke (Scada)
Scada (Tus saib xyuas lub zogchatolanddatacquisition) system yog siv los tswj thiab tswj cov khoom muaj peev xwm tshwj xeeb (cov cuab tam) Central cov ntaub ntawv tau txais thiab tswj hwm kev lag luam hauv nruab nrab, cov khoom siv dej Scada yog siv hauv cov khoom lag luam zoo sib xws hauv cov khoom sib xyaw. Scada tswj chaw zov me nyuam centrally thiab tswj hwm cov ntaub ntawv kev sib txuas lus nyob rau hauv cov ntaub ntawv kev sib txuas lus thiab cov txheej txheem kev tswj hwm cov chaw taws teeb kom tsim kom muaj kev sib txuas lus ntawm cov chaw taws teeb thiab cov chaw taws teeb Cov lag luam ua haujlwm zoo ib yam li kev qhib / kaw ntawm li qub thiab cov ntaub ntawv kev kawm thiab lub vev xaib ib puag ncig.
3, Kev tswj hwm cov kev tswj hwm hauv programmable logic maub los (PLC)
Plc yog raws li kev ua ntu zus los qhia microelectronics technology, Computer Technology, tsis siv neeg tswj thev naus laus zis thiab kev tsim ntawm cov khoom siv tshiab ntawm cov khoom lag luam tshiab. Cov kev cai Electrotechnical thoob ntiaj teb (IEC) tshaj tawm cov kev cai ntawm PLC: Cov Txheej Txheem Kev Ua Haujlwm ntawm cov tshuab hluav taws xob, tsim los siv rau cov kev thov hauv cov chaw muaj kev lag luam. Nws siv lub cim xeeb tseem ceeb, uas yog siv los khaws cov lus qhia rau kev ua cov ntawv qhia txog kev ua haujlwm thiab tswj ntau yam tshuab lossis cov txheej txheem ntau lawm. Programmable controllers thiab lawv cov khoom siv cuam tshuam yuav tsum tau tsim raws li qhov yooj yim nrog cov txheej txheem kev lag luam, thiab nws yog ib qho tseem ceeb ntawm Scada system lossis DCS tswj hwm.
Ntawm cov kev kawm ntawm cov tswj kev lag luam, daim ntawv no tsom rau cov qauv theem pib thiab hom kev muaj txuj ci tshuab hluav taws xob. Ntau hom kev tswj hwm muaj cov yam ntxwv sib txawv, yog li lawv yuav tsum tau xaiv raws li qhov xwm txheej thaum lawv tau siv tshwj xeeb.
