In order to realize real-time monitoring and timely alarm of dissolved oxygen（ DO） in aquaculture

put forward a DO monitoring system based on C# and LabVIEW

LabVIEW is mainly responsible for data collection

C# call DLL generated by LabVIEW

users send acquisition command to LabVIEW through C# program

and after LabVIEW receive the user’s command

data acquisition is carried out. The main feature of this system is according to culture period of aquatic products

this system dynamic calls DO prediction algorithm on upper PC

real-time transmit acquisition instruction to various LabVIEW subroutines

separates data acquisition and data analysis and processing

reduce CPU usage rate brought by LabVIEW serial polling communication. The system can alarm in time when the DO is over the set

which can ensure aquaculture water environment parameters is normal.
