Abstract

The invention relates to an anemorumbometer which comprises a wind speed measuring part and a signal processing part, wherein the wind speed measuring part comprises a casing and a wind speed measuring mechanism; the casing comprises three parts, namely, a wind inlet drum, a wind guide drum and a wind outlet drum; the wind speed measuring mechanism comprises a rotating blade and sensors; the rotating blade comprises a blade root and blade bodies circularly and evenly distributed around the blade root; a wind inlet gap exists between every two adjacent blade bodies, and one sensor is mounted on each blade body and is a Hall element; the rotating blade is connected onto the periphery of a support rod of a support plate through the blade root in a sleeve manner and can rotate relative to the support rod; the signal processing part comprises a conditioning circuit and an operating module, electric signals transmitted by the Hall elements are conditioned and operated, and the wind speed and direction are acquired.

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...
