I-DCS Control System
Incazelo Yesistimu
Inqubo yokutakula i-DMF iyinqubo evamile yokukhishwa kwamakhemikhali amakhemikhali, ebonakala ngezinga elikhulu lokuhlobana phakathi kwemingcele yenqubo kanye nemfuneko ephezulu yezinkomba zokubuyisela. Kusukela esimweni samanje, isistimu yensimbi evamile inzima ukufeza ukuqapha kwesikhathi sangempela nokusebenza ngempumelelo kwenqubo, ngakho-ke ukulawula kuvame ukungazinzi futhi ukwakheka kudlula izinga, okuthinta ukusebenza kahle kokukhiqiza kwamabhizinisi. Ngalesi sizathu, inkampani yethu kanye ne-Beijing University of Chemical Technology ngokuhlanganyela bathuthukise uhlelo lokulawula lwe-DCS lwekhompyutha yobunjiniyela egaywa kabusha ye-DMF.
Isistimu yokulawula ehlukaniselwe ikhompyutha iyindlela yokulawula ethuthuke kakhulu ebonwa yindilinga yokulawula yamazwe ngamazwe. Eminyakeni yamuva nje, sithuthukise uhlelo lokulawula ikhompuyutha olunemibhoshongo emibili lwenqubo yokutakula i-DMF, i-DMF-DCS (2), kanye nohlelo lokulawula ikhompuyutha olunemibhoshongo emithathu, olungajwayelana nendawo yokukhiqiza yezimboni futhi inokwethenjelwa okuphezulu kakhulu. Okufakwayo kuzinza kakhulu ukukhiqizwa kwenqubo yokugaywa kabusha futhi idlala indima ebalulekile ekuthuthukiseni okukhiphayo nekhwalithi yemikhiqizo kanye nokunciphisa ukusetshenziswa kwamandla.
Njengamanje, lolu hlelo selusetshenziswe ngempumelelo ezinkampanini ezinkulu zesikhumba zokwenziwa ezingaphezu kuka-20, futhi uhlelo lwakudala lusebenze ngokuzinza iminyaka engaphezu kwengu-17.
Isakhiwo sesistimu
Isistimu yokulawula ikhompuyutha esabalalisiwe (DCS) iyindlela yokulawula ethuthukisiwe eyamukelwa kabanzi. Ngokuvamile iqukethe isiteshi sokulawula, inethiwekhi yokulawula, isiteshi sokusebenza kanye nenethiwekhi yokuqapha. Uma sikhuluma kabanzi, i-DCS ingahlukaniswa ngezinhlobo ezintathu: uhlobo lwensimbi, uhlobo lwe-PLC nohlobo lwe-PC. Phakathi kwazo, i-PLC inokwethenjelwa okuphezulu kakhulu kwezimboni kanye nezinhlelo zokusebenza eziningi, ikakhulukazi kusukela ngawo-1990, i-PLC eminingi edumile yandisa ukucubungula kwe-analog nemisebenzi yokulawula i-PID, ngaleyo ndlela iyenze ibe nokuncintisana kakhulu.
I-COMPUTER yokulawula inqubo ye-DMF yokugaywa kabusha isekelwe ku-PC-DCS, kusetshenziswa uhlelo lwesiJalimane lwe-SIEMENS njengesiteshi sokulawula, kanye nekhompiyutha yezimboni ye-ADVANTECH njengesiteshi sokusebenza, esifakelwe isikrini esikhulu se-LED, iphrinta nekhibhodi yobunjiniyela. Inethiwekhi yokuxhumana yokulawula isivinini esiphezulu iyamukelwa phakathi kwesiteshi sokusebenza kanye nesiteshi sokulawula.
Umsebenzi wokulawula
Isiteshi sokulawula sakhiwe umqoqi wedatha wepharamitha i-ANLGC, shintsha isiqoqi sedatha yepharamitha SEQUC, isilawuli se-loop esihlakaniphile i-LOOPC nezinye izindlela zokulawula ezihlukaniselwe izindawo. Zonke izinhlobo zezilawuli zifakwe ama-microprocessors, ngakho-ke zingasebenza ngokujwayelekile kwimodi yokusekelayo uma kwenzeka ukwehluleka kwe-CPU esiteshini sokulawula, okuqinisekisa ngokugcwele ukwethembeka kwesistimu.
