Above-mentioned nuclear power generating sets further comprise giant-screen, its be connected same the computing machine on the switch and be connected.
Above-mentioned nuclear power generating sets further comprise printer, its be connected same the computing machine on the switch and be connected.
The utility model adopts scattered control system DCS, mainly be on man machine operation interface, to adopt digital control replacement simulation control, promptly operation and management information level adopt digitizing, particularly are exactly to have adopted the DCS operator station as man-machine interface, replace conventional instrument console panel platform.Its advantage is:
1) operating personnel's supervision and mode of operation and means have changed fully, only need to wait by screen display, keyboard, mouse nuclear power generating sets are monitored and operate that monitoring range dwindles greatly, and the centralized control level greatly improves.
2) monitoring efficiency and operational reliability greatly improve.Operator station adopts the simulation drawing picture to monitor and operation, intuitively is difficult for makeing mistakes.Each operation all has the execute key secondary to confirm, guarantees that operation is correct.
3) the pulpit looks are taken on a new look fully, and area can dwindle.
4) in addition owing to cancelled the quite complicated conventional console panel platform of wiring, make the wiring design simplification, installation workload reduces, and operational reliability also increases.Logic relay also almost completely is cancelled, and only surplus DCS exit relay dish makes the wiring design simplification, and installation workload reduces, and operational reliability increases.
