Abstract

The invention discloses an adaptive wind speed and wind direction detection system and method under the parafoil airborne situation. The system includes a paratrooper helmet, an ultrasonic anemometer, a rotatable wearable platform, a GPS antenna and an information processing module. The steps of the method: use an ultrasonic anemometer and a rotatable wearable platform to perform zero-point online calibration; perform main wind direction calibration on the ultrasonic anemometer; regard the transient phenomenon of wind speed as the effect of turbulent wind, and use the GPS information collected by the GPS antenna Solve the turbulent wind field information. The invention improves the detection accuracy of wind speed and wind direction.

Description

technical field [0001] The invention belongs to the field of parafoil airborne, and in particular relates to a wind speed and wind direction detection system and method. Background technique [0002] In the parafoil airdrop situation, the wind speed and wind direction have a great influence on its flight state, so it is particularly important to accurately know the wind speed and wind direction in the parafoil airdrop landing area. When using an ultrasonic anemometer to measure wind speed and direction, the anemometer is easily affected by zero drift, water fog and ice, main wind direction and range effective range, and turbulent wind, making it difficult to collect accurate wind field data. Contents of the invention [0003] In order to solve the technical problems raised by the above-mentioned background technology, the present invention proposes an adaptive wind speed and wind direction detection system and method under the parafoil airborne situation. [0004] In orde...
