The conventional external water net system usually applies independent and decentralized control method
it is often interrupted due to complex operations.Employing the one-touch desalted water production concentrated control can greatly reduce the possibility of misoperation and the device loss caused by misoperation.On the basis of field control system(FCS)and rich device information
the equipment interlock protect mode was enriched
an entire one-touch water production control logic was designed
and the one-touch automatic control for four sub-systems was realized
such as the original water pretreatment system
the ultrafitration water treatment system
the reverse osmosis water treatment system and iron desaltation system.Good operation effect was obtained after debugging.
