Abstract

The present invention relates to an anemometer, comprising a wind speed measuring part and a signal processing part, wherein the wind speed measuring part includes a casing and an wind speed measuring mechanism; the casing is composed of three parts, namely an air inlet tube and an air guiding tube , the air outlet tube; the wind speed measuring mechanism includes a rotating blade and a sensor; the rotating blade includes a blade root and an annular blade body uniformly distributed around the blade root; there is an air inlet gap between two adjacent blade bodies , a sensor is installed on each blade body, and the sensor is a Hall element; the rotating blade is sleeved on the periphery of the support rod on the support plate through the blade root, and the rotating blade can be made relative to the support rod Rotational movement; the signal processing part includes a conditioning circuit and an operation module, which regulates and calculates the electrical signal transmitted by the Hall element to obtain the wind speed and wind direction.

Description

technical field [0001] The invention relates to an anemometer. Background technique [0002] Wind speed and direction measurement technology has a wide range of applications: for example, in the field of meteorology, it provides accurate data for typhoon monitoring; in the field of civil aviation, it provides reliable wind speed and direction reference for aircraft takeoff and landing; in the construction of highways and bridges, it provides a basis for its design and construction ; In the field of new energy, especially in the field of wind power generation with good development prospects, wind measurement technology plays an important role. [0003] In the measurement of air pollution, in order to measure the local atmospheric flow, an anemometer is usually used to measure the wind direction and wind speed of the air. The most commonly used weather station is the wind cup anemometer, which consists of three parabolic cone empty cups fixed on the bracket at 120° to each ot...
