Abstract

This application relates to a fiber grating wind speed and direction sensor, including a thin-walled cylinder and a package body. The upper middle part of the thin-walled cylinder is hollowed out, and a third equal-strength cantilever beam is installed in this area. The central axis of the upper and lower surfaces of the third equal-strength cantilever beam The fiber grating sensors are symmetrically pasted on the top respectively; it also includes a direction cam, a cylindrical cam and a push rod arranged in the package body, and a horizontal equal-strength cantilever beam is respectively connected to the upper and lower parts of the inner side of the package body, and is hung and installed on the top side of the package body A vertical equal-intensity cantilever beam, fiber grating sensors are pasted on both sides of the equal-intensity cantilever beam, and a permanent magnet is provided at the free end to sense the magnetic force change of the permanent magnet on the equal-intensity cantilever beam. The application has a light structure and is not easy to be damaged, and realizes real-time online monitoring of wind speed and direction by utilizing the physical properties of fiber gratings such as small size, anti-electromagnetic interference, good electrical insulation performance and large transportation capacity.

Description

Technical field [0001] The present application relates to a fiber-optic raster wind speed winding sensor, which is suitable for the technical field of wind speed wind direction detection. Background technique [0002] The wind speed wind direction measurement technology application is very wide: in the field of agriculture, the wind speed has an important impact on the harvest of farmland; in the field of meteorological, accurate wind direction change data for marine meteorological warning systems, wind speed wind is predicting typhoon coverage and "operation" "One of the important parameters of the trajectory; in the field of clean energy, the state attaches great importance to wind energy development and utilization. Currently used wind speed windsome measuring means: capacitive force sensor, ultrasonic force sensor, dielectric force sensor. The above sensor requires active power supply, and the sensing signal is easily electromagnetic interference during transmission. [0003]...
