Abstract

The invention relates to wind speed and direction measurement technology, and aims to provide an anemoclinograph wind meter with high precision, good stability and low cost. The anemoclinograph wind meter comprises a wind measuring head and a signal processing device, wherein the wind measuring head consists of a shell, pull pressure sensors and a support bar; a horizontal circular section in the hollow shell is distributed with three pull pressure sensors with the same specification, which are symmetrically distributed at an interval of 120 degrees around a center of a circle; one end of each pull pressure sensor is fixed on the inner wall of the shell, while the other end is fixed on the support bar; the shell is not contacted with the support bar; wind pressure born by the shell is gathered on the support bar through the sensors, so the resultant force of the pull pressure of the sensors corresponds to the wind pressure; and the pressure direction indicates the wind direction, and the pressure and the wind speed have a certain functional relation which depends on the shape and size of the shell and can be calculated through a fluid mechanics theory or obtained through wind tunnel tests. The anemoclinograph wind meter can be used for wind generating systems, and also can be applied to the fields such as meteorology, transportation and the like.

Description

[0001] Technical Field The present invention relates to a wind speed and direction measurement technology. 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 field of wind power generation, the most widely used wind measuring equipment is the wind measuring system composed of wind cup and wind vane. The main problem is that the mechanical rotating parts are easy to wear, and may freeze, block, break, etc. when the climate changes; curr...
