DCS Control System
Kufotokozera Kwadongosolo
DMF kuchira ndondomeko ndi mmene mankhwala distillation ndondomeko, yodziwika ndi mlingo waukulu wa malumikizanidwe ndondomeko magawo ndi chofunika kwambiri zizindikiro kuchira. Kuchokera pazochitika zamakono, dongosolo lachida lachidziwitso ndilovuta kukwaniritsa nthawi yeniyeni komanso yowunikira ndondomekoyi, kotero kulamulira nthawi zambiri kumakhala kosasunthika ndipo mapangidwe ake amaposa muyezo, zomwe zimakhudza kupanga mabizinesi. Pazifukwa izi, kampani yathu ndi Beijing University of Chemical Technology mogwirizana adapanga makina owongolera a DCS a makompyuta obwezeretsanso DMF.
Computer decentralized control mode ndiye njira yotsogola kwambiri yozindikiridwa ndi gulu la mayiko olamulira. M'zaka zaposachedwa, tapanga makina owongolera makompyuta okhala ndi nsanja ziwiri zowongolera makina a DMF, DMF-DCS (2), komanso njira yowongolera makompyuta yokhala ndi nsanja zitatu, yomwe ingagwirizane ndi malo opanga mafakitale komanso ali ndi kudalirika kwakukulu. Kuyika kwake kumakhazikika kwambiri popanga njira yobwezeretsanso ndipo kumagwira ntchito yofunika kwambiri pakuwongolera zotulutsa ndi mtundu wazinthu komanso kuchepetsa kugwiritsa ntchito mphamvu.
Pakalipano, dongosololi lakhazikitsidwa bwino m'mabizinesi akuluakulu opangira zikopa oposa 20, ndipo makina oyambirira akhala akugwira ntchito kwa zaka zoposa 17.
Kapangidwe kadongosolo
Distributed computer control system (DCS) ndi njira yovomerezeka yovomerezeka ndi zotsogola. Nthawi zambiri imakhala ndi malo owongolera, maukonde owongolera, malo ogwirira ntchito ndi netiweki yowunikira. Mwachidule, DCS ikhoza kugawidwa m'mitundu itatu: mtundu wa chida, mtundu wa PLC ndi mtundu wa PC. Pakati pawo, PLC ili ndi kudalirika kwakukulu kwa mafakitale ndi ntchito zambiri, makamaka kuyambira zaka za m'ma 1990, PLC ambiri otchuka adawonjezera ma analogi ndi ntchito zolamulira za PID, motero zimapangitsa kuti zikhale zopikisana.
Dongosolo loyang'anira COMPUTER la DMF recycling process likuchokera pa PC-DCS, pogwiritsa ntchito dongosolo la Germany SIEMENS monga malo owongolera, ndi makina apakompyuta a ADVANTECH monga malo opangira, okhala ndi chophimba chachikulu cha LED, chosindikizira ndi kiyibodi yaukadaulo. Njira yolumikizirana yothamanga kwambiri imatengedwa pakati pa malo ogwirira ntchito ndi malo owongolera.
Control ntchito
Malo owongolera amapangidwa ndi otolera ma data a ANLGC, otolera ma data akusintha SEQUC, wowongolera wanzeru LOOPC ndi njira zina zowongolera. Olamulira amitundu yonse ali ndi ma microprocessors, kotero amatha kugwira ntchito nthawi zonse mukamasunga zosunga zobwezeretsera ngati CPU ikulephera kuwongolera, kutsimikizira kudalirika kwadongosolo.
