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 two-dimensional solid wind speed and direction measuring instrument and a measuring method thereof. The two-dimensional solid wind speed and direction measuring instrument comprises a weather cylinder, pressure pipes and sensors, wherein small holes in the even number are distributed in the cylindrical surface of the weather cylinder; one end of each pressure pipe is communicated with the small holes in the cylindrical surface of the weather cylinder, and the other end of the pressure pipe is communicated with the sensors; and the sensors are used for measuring the pressure-intensity difference between two small holes, whose horizontal distance equals the diameter of the weather cylinder, in the cylindrical surface of the weather cylinder. The measuring method comprises that the measuring instrument is fixed, and the orientation of the measuring instrument is determined; when wind in the horizontal direction acts on the instrument, the pressure-intensity difference between each two points, whose horizontal distance equals the diameter of the weather cylinder, in the cylindrical surface of the weather cylinder of the measuring instrument is measured; according to the relations between wind pressure distribution and wind speed / direction, the wind speed and the wind direction relative to the weather cylinder are calculated via the obtained pressure-intensity differences; and according to the determined orientation of the measuring instrument, the practical wind direction is calculated. Compared with a common wind speed and direction indicator, the two-dimensional solid wind speed and direction measuring instrument disclosed by the invention has the advantages of being small in size, fast in response, and not easy to damage.

Description

technical field [0001] The invention relates to the technical field of wind speed and wind direction measurement, in particular to a solid-state two-dimensional wind speed and direction measuring instrument and a measuring method thereof. 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 parabol...
