Wind measuring device

Abstract

The invention discloses a wind measurement device which comprises a buoy body, a wind measurement assembly and a posture correction assembly. The wind measuring assembly is arranged on the buoy body and used for measuring a wind field; the posture correction assembly is arranged on the buoy body and used for correcting the posture of the wind measurement assembly; the posture correction assembly comprises a fixing frame, a first correction frame and a second correction frame; the fixing frame is arranged at the buoyancy center of the buoy body. The first correction frame is rotatably arranged on the fixing frame and used for rotating relative to the fixing frame in the first direction; the second correction frame is rotatably arranged on the first correction frame, is used for rotating relative to the first correction frame in the second direction, and is used for placing the wind measurement assembly. The wind measuring device does not need to be provided with a satellite inertial navigation device or a complex swing table system, the power consumption and complexity of the device can be reduced, and the reliability of the device is remarkably improved; meanwhile, the accuracy of a measurement result is obviously improved, and wind field measurement can be accurately carried out even in a large storm wave environment.

Description

technical field [0001] The invention relates to the technical field of wind field measurement, in particular to a wind measuring device. Background technique [0002] At present, in the floating wind measuring device, the satellite inertial navigation system is mainly used as the attitude and velocity measurement equipment, and the attitude and velocity are corrected in real time to accurately measure the wind field; or the swing table system is used for compensation and correction; or the attitude is not corrected, and It is done by averaging the measurement results over a period of time. [0003] However, using the satellite inertial navigation system to measure attitude and speed requires the installation of a high-performance satellite inertial navigation system, which will increase the power consumption of the maritime system, and the satellite inertial navigation system cannot guarantee continuous operation under the continuous operation of the sea environment.

Problems solved by technology

[0003] However, using the satellite inertial navigation system to measure attitude and speed requires the installation of a high-performance satellite inertial navigation system, which will increase the power consumption of the maritime system, and the satellite inertial navigation system cannot guarantee continuous operation under the continuous operation of the sea environment. Stable and accurate work; similarly, the swing table system consumes a lot of power and has high environmental requirements, and cannot work normally on the offshore buoy platform. The swing table system has a limited adjustment range and cannot guarantee correct correction under various sea conditions; without attitude correction In the case of a certain period of time, the average processing of the results and the correction of the orientation by additional sensors are only idealized processing methods, and the results will inevitably deviate from the accurate value of the wind field. At the same time, when encountering shaking When the angle is large, the deviation of the average result will increase significantly, which will greatly affect the measurement results
