Embodiment 1

[0027] figure 1 It is a structural schematic diagram of an embodiment of the present invention; refer to figure 1 As shown, in this embodiment, the solid-state two-dimensional anemometer includes a wind receiving cylinder 2, a pressure guiding tube 5 and a sensor 6; the height of the wind receiving cylinder is 120mm, and the diameter is 20mm; the wind receiving cylinder The top is a hemispherical hood 1; the number of holes 3 on the wind-receiving cylinder is at least 6, and 8 are selected in this embodiment, and the holes 3 on the wind-receiving cylinder are evenly distributed on the wind-receiving cylinder. On the same horizontal circumference of the cylinder 2; the small holes 3 on the cylinder surface of the wind receiving cylinder are distributed in the middle section of the wind receiving cylinder 2, and try to avoid the abnormal wind pressure distribution area at the two ends of the wind receiving cylinder 2; The number of small holes 4 at the bottom of the wind-receiv...

Embodiment 2

[0042] The number N of small holes 3 on the wind-receiving cylinder is at least 6; when N increases, more measured values ​​can be used for solving, and the reliability and accuracy of the measured results are higher. The small holes 3 do not need to be distributed at the same height. In the stable wind pressure distribution area in the middle section of the wind receiving cylinder, the partial pressure distribution on different horizontal circles is consistent. Another specific embodiment of the present invention is provided when the number N of the small holes 3 on the wind-receiving cylinder is chosen to be a minimum value of 6 and the small holes 3 are distributed on different horizontal circumferences.

Abstract

The invention discloses a measurement method using a two-dimensional solid-state anemometer. The two-dimensional solid-state anemometer includes: a wind receiving cylinder, a pressure guiding tube, and a sensor; an even number of small holes are distributed on the cylindrical surface of the wind receiving cylinder; one end of the pressure guiding tube is connected with the small holes on the wind receiving cylindrical surface, and the other One end communicates with the sensor; the sensor is used to measure the pressure difference between two small holes on the cylinder surface of the wind receiving cylinder whose horizontal distance is equal to the diameter of the wind receiving cylinder. The measuring method of this two-dimensional anemometer comprises: fixing the measuring instrument, determining the orientation of the measuring instrument; measuring the pressure difference on each pair of points whose horizontal distance is the diameter of the wind receiving cylinder on the wind receiving cylinder surface of the measuring measuring instrument; Pressure difference, according to the relationship between the wind pressure distribution on the cylindrical surface and the wind speed and direction, calculate the wind speed and the relative wind direction relative to the wind receiving cylinder; calculate the actual wind direction according to the determined orientation of the measuring instrument. The two-dimensional solid-state anemometer disclosed by the invention has the advantages of small volume, non-damage and fast response.

Description

technical field [0001] The invention relates to the technical field of wind speed and wind direction measurement, in particular to a measurement method using a solid-state two-dimensional wind speed and direction measuring instrument. Background technique [0002] Wind speed and wind direction are important meteorological parameters, which are of great significance to people's daily life, meteorological environment, national defense aviation, industrial and agricultural production, and transportation. Therefore, wind speed and wind direction measuring instruments have been widely used in many occasions. [0003] There are many kinds of wind speed and wind direction measurement principles and corresponding measuring instruments. Among them, the mechanical wind speed and direction instrument is the standard for meteorological observation, which is composed of a wind cup anemometer and a wind vane. In the wind cup anemometer, there are three or four hemispherical or parabolic e...
