AI Technical Summary
The existing fixed dredging modules cannot adaptively adjust to tidal changes and meteorological disturbances, which makes it impossible for the guide vanes to maintain the optimal angle of flow for a long time. This leads to a decrease in sediment collection efficiency, a lack of scientific determination of when to start dredging operations, and a tendency for dry dredging or clogging of the channel.
By generating a time-series network based on tidal flow prediction to predict future flow velocity and direction sequences, and combining the material deformation response curve of the guide vane with the flow-structure coupling simulation, the target attitude parameters of the guide vane are calculated, and an electrothermal drive signal is generated to adjust the attitude of the guide vane. The timing of dredging is determined by combining the silt thickness data in the channel.
It enables the fixed dredging module to autonomously sense and coordinate with the dynamic changes in water flow, improving the targeting and efficiency of dredging operations and avoiding the lag in the attitude control of the guide plate and the improper start-up of the sludge pumping operation.
