Problems solved by technology
[0026] The technical problem to be solved by the present invention is: due to the double-sided collision constraints of bollard mooring force and fender squeeze force during mooring loading and unloading, and the intermittent random excitation of the load of the spreader, the traditional measurement method It is difficult to accurately measure the ship's natural period, steady inclination and average draft during mooring loading and unloading, so it is impossible to monitor and warn the ship's floating state and stability in real time during mooring loading and unloading

A system for multi-quay bridges that monitors the floating state and stability of container ships during mooring loading and unloading. It utilizes the small ship swaying motion excited during mooring loading and unloading and the dynamic inclination sensor installed on the quay bridge spreader. Tide level, stowage operation, ship structure, spreader position, sling tightness, twistlock opening and closing, spreader inclination and other information, through the superimposition, splicing and integration of multi-quay bridge spreader monitoring data, mooring constraints and partial loading and unloading incentives Free ship swaying, solving the best fitting parameters of the nonlinear curve model, obtaining the average draft data instantaneously when the cable is loosened in the box, estimating the initial stability corrected by the free liquid surface, etc. High, realize real-time monitoring and early warning of the floating state and stability of container ships during mooring loading and unloading; thus provide data reference for the wharf and the ship to make timely stowage or ballast adjustments, and prevent container falling into the water caused by wharf loading and unloading operations. Accident disasters such as ship capsizing and channel blockage.
Description
technical field [0001] The invention relates to a method and device for monitoring the floating state and stability of a container ship during mooring loading and unloading, especially for single or multiple container quay cranes working together, utilizing the small ship shaking motion and The dynamic inclination sensor installed on the quay crane spreader, according to the information of the wharf wind and wave, wharf tide level, stowage operation, ship structure, spreader position, sling tightness, twist lock opening and closing, spreader inclination, etc., through the multi-quay crane Superimposition, splicing and integration of inclination data, local free ship sway without mooring constraints and loading and unloading excitation, best fitting parameters for solving nonlinear curve models, average draft obtained instantaneously at the beginning of boxing and loosening cables, estimation corrected by free liquid surface The high initial stability algorithm solves the natur...
