Abstract

The invention relates to the field of wind speed and wind direction measurement, in particular to a wind speed and wind direction measurement method and device based on a floating platform, and the method comprises the steps: obtaining integrated navigation information, and calculating the ground speed and attitude conversion matrix of the floating platform according to the integrated navigation information; acquiring atmospheric data measurement information, and calculating the vacuum speed of the floating platform according to the atmospheric data measurement information; and obtaining a ground speed and attitude conversion matrix of the floating platform and a vacuum speed calculation result, and calculating the wind speed and wind direction of the floating platform to obtain the wind speed and wind direction of the floating platform. The technical scheme is convenient and flexible to use, the problem that a common wind measurement method is not suitable for large-area continuous real-time wind speed and wind direction measurement is solved, the wind resistance of the floating platform is improved, and stable control over the platform is achieved.

Description

technical field [0001] The invention relates to the field of wind speed and direction measurement of floating platforms, in particular to a method and device for measuring wind speed and direction based on floating platforms. Background technique [0002] A floating platform has a low flying speed and is easily affected by wind disturbance. When the airspeed decreases due to wind disturbance, the lift force of the floating platform drops sharply, and the resistance increases at the same time, resulting in a stall phenomenon. In order to improve the wind resistance performance of the platform and realize stable control, it is necessary to measure the wind speed and wind direction. The current methods of wind measurement mainly include balloon wind measurement, wind profiler and sounding rocket. [0003] Balloon wind measurement is to place the wireless radiosonde on the balloon, use optical theodolite, radio theodolite, wind radar, navigation system and other equipment to t...
