Dissolved oxygen monitoring and flow field simulating system and operating method thereof

Abstract

A dissolved oxygen monitoring and flow field simulation system monitors dissolved oxygen data in an aquaculture farm and includes a model building module, a flow field analysis module, dissolved oxygen sensors, a central processing module, and a waterwheel operation module. The model building module generates a farm model based on the aquaculture farm and meshes the model, setting the mesh type and size to discretize the virtual farm model into multiple unit regions. The flow field analysis module sets simulation parameters to perform flow field analysis on the unit regions and sets the sensor placement areas. The dissolved oxygen sensors are placed in the sensor placement areas and sense the dissolved oxygen value of the aquaculture farm. The waterwheel operation module starts or stops the waterwheel units based on the dissolved oxygen analysis results to maintain the real-time dissolved oxygen value of the aquaculture farm within a predetermined range.
