Problems solved by technology

However, the positioning accuracy of GPS is limited, and the position calculation of the acceleration sensor in the existing platform will accumulate errors, which will cause the platform to generate cumulative deviations in the ocean fluctuation environment, which will bring welding, hoisting, and processing problems to the ultra-large floating platform operations. The hazards of increased operating errors

Abstract

The invention discloses an acoustic monitoring method for the working state of an ultra-large floating platform. The acoustic monitoring method is applied to a floating platform working state monitoring system comprising a platform, a seabed depth acoustic measurer, a sea surface height acoustic measurer, a seabed sediment acoustic measurer, and an attitude measurement sensor. The attitude measurement sensor measurement platform is controlled to obtain absolute attitude data; the sea surface height acoustic measurer is controlled to measure the sea surface to obtain sea surface state data; theseabed depth acoustic measurer is controlled to measure the seabed to obtain seabed state data; the seabed sediment acoustic measurer is controlled to measure the seabed to obtain seabed layering andsediment type data; and on the basis of the absolute attitude data, the sea surface state data, the seabed state data and the seabed layering and substrate type data, working state data are constructed, and real-time comprehensive monitoring of the platform and an operation object is realized.

Description

technical field [0001] The application relates to the field of acoustic positioning of floating platforms, in particular to an acoustic monitoring method for the operating state of a super-large floating platform. Background technique [0002] When the current ultra-large floating platforms are operating in the ocean, such as wind power installation, oil exploration and production, etc., under the constraints of large platform area, large volume, large bearing capacity, long working hours, and complicated actual sea environment conditions, because In the absence of reference objects, it is difficult to accurately grasp the positioning information of the platform and its own status information. Usually, it is necessary to install multiple measurement systems such as inclination sensors, acceleration sensors, and GPS positioning devices, and to realize the dynamic positioning and balance system of the platform through calculation and control. The working characteristics of its...
