DCS Kudzora System
Tsanangudzo Yehurongwa
DMF kudzoreredza maitiro ndeye yakajairwa kemikari distillation process, inoratidzwa nehukuru hukuru hwekuwirirana pakati pemaitiro paramita uye chinodiwa chepamusoro chezviratidzo zvekudzoreredza. Kubva pane zvazvino mamiriro, iyo yakajairwa chiridzwa sisitimu yakaoma kuwana chaiyo-nguva uye inoshanda yekutarisa maitiro, saka kutonga kunowanzo kusagadzikana uye kuumbwa kunodarika mwero, izvo zvinokanganisa kugadzirwa kwemabhizinesi. Nechikonzero ichi, kambani yedu neBeijing University yeChemical Technology vakabatana vakagadzira iyo DCS control system yeDMF yekudzokorodza engineering komputa.
Computer decentralized control system ndiyo yakanyanyisa kudzora modhi inocherechedzwa nepasi rose control denderedzwa. Mumakore achangopfuura, takagadzira maviri-tower-double-effect computer control system yeDMF recovery process, DMF-DCS (2), uye matatu-shongwe matatu-efect control yemakomputa system, inogona kuenderana nemamiriro ekugadzira maindasitiri uye. ane kuvimbika kwakanyanya. Kupinza kwayo kunodzikamisa zvikuru kugadzirwa kwemaitiro ekudzokorodza uye inoita basa rakakosha mukuvandudza kubuda uye kunaka kwezvigadzirwa uye kuderedza kushandiswa kwesimba.
Parizvino, sisitimu iyi yakashandiswa zvinobudirira mumabhizinesi makuru ematehwe ematehwe anopfuura makumi maviri, uye hurongwa hwekutanga hwave huchishanda zvakatsiga kweanopfuura makore gumi nemanomwe.
Mamiriro ehurongwa
Distributed computer control system (DCS) inzira inogamuchirwa nevakawanda yepamusorosoro nzira. Iyo inowanzo ine yekudzora chiteshi, control network, chiteshi chiteshi uye yekutarisa network. Pakutaura, DCS inogona kukamurwa kuita mhando nhatu: chiridzwa rudzi, PLC mhando uye PC mhando. Pakati pazvo, PLC ine kuvimbika kwakanyanya kwemaindasitiri uye kuwedzera uye kuwedzera maapplication, kunyanya kubva kuma1990s, mazhinji ane mukurumbira PLC akawedzera analog kugadzirisa uye PID kutonga mabasa, nekudaro zvichiita kuti iwedzere kukwikwidza.
Iyo COMPUTER control system yeDMF yekudzokorodza maitiro yakavakirwa paPC-DCS, uchishandisa yeGerman SIEMENS sisitimu sechiteshi chekutonga, uye ADVANTECH indasitiri komputa sechiteshi chekushandisa, yakashongedzerwa nehombe screen LED, printer uye engineering keyboard. Iyo yakakwirira-yekumhanyisa kudzora kutaurirana network inogamuchirwa pakati penzvimbo yekuvhiya uye chiteshi chekudzora.
Kudzora basa
Iyo chiteshi chekudzora inoumbwa neparameter data muunganidzi ANLGC, chinja paramende dhata muunganidzi SEQUC, akangwara loop controller LOOPC uye dzimwe decentralized kudzora nzira. Ese marudzi evanodzora akashongedzerwa nemamicroprocessors, saka vanogona kushanda zvakajairwa mu backup modhi kana CPU kutadza kwechiteshi chekutonga, ichinyatso kuvimbisa kuvimbika kweiyo system.
