Problems solved by technology

However, the existing wave compensation measurement mechanism for the six-degree-of-freedom platform requires complex algorithms to directly calculate the compensation required strokes of each servo cylinder, which is difficult to measure, high in measurement costs, and low in compensation accuracy. It is necessary to continuously optimize the algorithm to improve Compensation accuracy

Abstract

The invention discloses a wave compensation measuring device, a measuring method and an applicationthereof in an ocean platform. The wave compensation measuring device comprises acompensation drive unit and a platform displacement measurement unit, the compensation drive unit comprises a rolling compensation drive device, a pitch compensation drive device, a heave compensation drive device and a drive connection rod; the connection between an upper measurement plate and a lower measurement plate is connected with six linear displacement sensors. The platform displacement measurement unit is arranged to simulatethe six degrees of freedom platform, whereinthe six linear displacement sensors correspond to the six servo cylinders of the six degrees of freedom platform; a compensation drive unit is arranged so as to conductwave compensations on theplatform displacement measurement unit, thus the wave compensation volume of theservo cylinders of the six degrees of freedom platform six is measured, the complex parallel connection machine program algorithm is converted into a mechanical news transmission mechanism, and the wave compensation measurement difficulty is reduced.

Description

technical field [0001] The invention relates to the field of marine transportation operation equipment, in particular to a wave compensation measuring device, a measuring method and an ocean platform using the same. Background technique [0002] Due to the influence of wind and waves, ships operating at sea will sway irregularly, which seriously affects the safety of staff when working at sea. Therefore, the six-degree-of-freedom platform is often set up, and the rolling, pitching and heaving of the upper platform are compensated in real time by adjusting the expansion and swing of the six servo cylinders, so that the upper platform remains stable. However, the existing wave compensation measurement mechanism for the six-degree-of-freedom platform requires complex algorithms to directly calculate the compensation required strokes of each servo cylinder, which is difficult to measure, high in measurement costs, and low in compensation accuracy. It is necessary to continuously...
