A wind direction and wind speed measurement device based on the principle of magnetic levitation

Abstract

Disclosed in the invention is a magnetic-levitation-principle-based wind direction and wind speed measuring device comprising a supporting frame mechanism, a power module, a signal acquisition system, a signal processing system and a wireless communication processing system. The signal acquisition system consists of a wind speed collecting mechanism, a wind direction collecting mechanism and a level meter. The signal processing system includes a wind speed processing mechanism, a wind direction processing mechanism, a horizontal control mechanism and a storage device. According to the device, a mechanical-wearing-free effect of a bearing is realized based on a magnetic levitation principle, so that the starting wind speed of the device is effectively reduced and problems of great mechanical wearing loss and large starting wind speed of the traditional wind measuring device can be solved. Meanwhile, the device is also provided with the level meter for detecting whether the work platform is in a level state and a wind direction measuring mechanism and thus the device can be in a level state during working and the wind speed measuring mechanism align the wind direction, so that measurement precision of the device is enhanced.

Description

technical field [0001] The invention relates to the technical field of wind speed measurement, in particular to a wind direction and wind speed measurement device based on the principle of magnetic levitation. Background technique [0002] Wind direction and wind speed are important information parameters of the natural environment. The current society pays more and more attention to global environmental protection. Therefore, wind direction and wind speed, especially wind speed, need to be measured in real time and accurately in a large range. There are also many kinds of wind speed measurement devices in the prior art. Among them, the five-hole probe is relatively expensive and is generally limited to laboratory use; Pitot tube anemometer, the temperature has a great influence on its measurement results; ultrasonic anemometer, laser doppler The requirements for installation are very strict, the structure is more complex, the troubleshooting is difficult, and the anti-inter...
