AI Technical Summary

Technical Problem

Traditional gate control methods rely on manual experience or simple hydraulic formulas, which are difficult to accurately simulate complex and ever-changing river conditions. This leads to deviations in water level control, making it impossible to meet dynamic target water level requirements. Furthermore, the lack of effective use of historical data makes it difficult to achieve accurate and effective water level control and flow field simulation.

Method used

The method of river gate scheduling and flow field visualization is adopted. By combining the execution of a one-dimensional hydrodynamic model with data-corrected gate passage formulas through computer equipment, a two-dimensional hydrodynamic model is constructed using the alternating implicit ADI algorithm, and the flow field is visualized by combining particle rendering technology, so as to realize the quantification, modeling and standardization of gate scheduling.

Benefits of technology

It improves the scientific nature and predictability of gate scheduling, enabling real-time and precise characterization of flow velocity and water level changes, proactive detection of safety risks, and enhanced safety and management efficiency of water conservancy projects.

Abstract

The application discloses a river channel gate scheduling and flow field visualization method, equipment and medium, the method predicts the over-gate flow curve through a one-dimensional hydrodynamic model and obtains executable discharge through the gate by periodical average, improves the gate opening calculation accuracy by combining the over-gate formula corrected by historical data, accurately adapts to the dynamic target water level regulation and control demand, and constructs a closed-loop mechanism of "discharge prediction-gate scheduling scheme allocation-scheme evaluation and correction-final decision display". The two-dimensional hydrodynamic model adopting the alternating implicit ADI algorithm and the OpenMP parallelization calculation technology realizes virtual-real mapping of the gate operation state, can quickly simulate and evaluate the upstream and downstream flow fields and water level fields after the implementation of the scheduling scheme, timely discovers and adjusts the adverse flow state, avoids safety hazards such as flow turbulence and scour, changes the gate scheduling from experience dependence to data and model driven scientific decision-making, and provides strong technical support for river water conservancy engineering management.
