DCS Tswj System
System Description
DMF rov qab txheej txheem yog cov txheej txheem tshuaj distillation ib txwm, uas muaj ntau yam kev sib raug zoo ntawm cov txheej txheem tsis ua haujlwm thiab qhov yuav tsum tau muaj rau cov ntsuas kev rov qab los. Los ntawm cov xwm txheej tam sim no, cov cuab yeej siv tau yooj yim ua kom tiav lub sijhawm thiab kev saib xyuas zoo ntawm cov txheej txheem, yog li kev tswj xyuas feem ntau tsis ruaj khov thiab muaj pes tsawg leeg tshaj tus qauv, uas cuam tshuam rau kev tsim khoom ntawm cov lag luam. Vim li no, peb lub tuam txhab thiab Beijing University of Chemical Technology tau sib koom ua ke tsim DCS tswj qhov system ntawm DMF rov ua haujlwm engineering computer.
Khoos phis tawj decentralized tswj system yog hom kev tswj hwm qib siab tshaj plaws uas tau lees paub los ntawm kev tswj hwm thoob ntiaj teb. Nyob rau hauv xyoo tas los no, peb tau tsim ib tug ob-ntaus-ntaus-zoo computer tswj system rau DMF rov qab txheej txheem, DMF-DCS (2), thiab peb-ntaus peb-tshuaj computer tswj system, uas tuaj yeem hloov mus rau qhov chaw tsim khoom lag luam thiab muaj kev ntseeg siab heev. Nws cov tswv yim zoo stabilizes kev tsim cov txheej txheem rov ua dua tshiab thiab ua lub luag haujlwm tseem ceeb hauv kev txhim kho cov khoom tsim tawm thiab cov khoom zoo thiab txo qis kev siv zog.
Tam sim no, lub kaw lus tau ua tiav hauv ntau tshaj 20 lub tuam txhab tawv hluavtaws loj, thiab cov txheej txheem ntxov tshaj plaws tau ua haujlwm ruaj khov rau ntau tshaj 17 xyoo.
Cov qauv tsim
Distributed computer control system (DCS) yog ib txoj kev tswj hwm tau dav dav. Nws feem ntau muaj chaw nres tsheb tswj, tswj network, chaw nres tsheb ua haujlwm thiab saib xyuas lub network. Hais dav dav, DCS tuaj yeem muab faib ua peb hom: hom ntsuas, PLC hom thiab PC hom. Ntawm lawv, PLC muaj kev ntseeg siab heev thiab ntau thiab ntau daim ntawv thov, tshwj xeeb tshaj yog txij li xyoo 1990, ntau lub npe nrov PLC nce kev ua haujlwm analog thiab PID tswj kev ua haujlwm, yog li ua rau nws muaj kev sib tw ntau dua.
Lub COMPUTER tswj qhov txheej txheem ntawm DMF rov ua dua txheej txheem yog raws li PC-DCS, siv German SIEMENS system ua qhov chaw tswj, thiab ADVANTECH muaj lub computer ua qhov chaw ua haujlwm, nruab nrog lub vijtsam loj LED, lub tshuab luam ntawv thiab cov keyboard engineering. Kev tswj hwm kev sib txuas lus ceev ceev tau txais los ntawm qhov chaw nres tsheb ua haujlwm thiab chaw nres tsheb tswj.
Tswj muaj nuj nqi
Chaw nres tsheb tswj yog tsim los ntawm cov ntaub ntawv parameter cov ntaub ntawv khaws cia ANLGC, hloov cov ntaub ntawv hloov pauv cov ntaub ntawv sau SEQUC, ntse lub voj tswj LOOPC thiab lwm yam kev tswj hwm kev tswj hwm. Txhua yam ntawm cov maub los tau nruab nrog microprocessors, yog li lawv tuaj yeem ua haujlwm ib txwm nyob hauv hom thaub qab thaum CPU tsis ua haujlwm ntawm qhov chaw tswj hwm, tag nrho lav qhov kev ntseeg tau ntawm lub kaw lus.
