AI Technical Summary
Existing technologies are insufficient to effectively address the wave rise problem caused by ships navigating within tunnels, leading to facility flooding and ship safety risks. Furthermore, traditional speed limit methods cannot take into account the differences between ships of different tonnages, resulting in low navigation efficiency.
By acquiring three-dimensional geometric data of ships and hydraulic boundaries of tunnels through multi-dimensional sensing devices, the blockage ratio coefficient is calculated, a ship wave response model in confined waters is established, the critical safe speed is calculated in reverse, and graded speed control is implemented to generate personalized speed limit commands, including surge suppression acceleration, threshold locking cruise and distance coupling deceleration strategies.
It achieves dynamic optimal control of vessels of different tonnages, improves navigation efficiency, prevents wave overflow, ensures facility safety, and avoids resource waste and safety risks.
