The invention is suitable for the technical field of wind speed and wind direction detection, and provides a wind speed and wind direction testing device and a testing method. The wind speed and winddirection testing device comprises a testing head, a supporting rod, pressure sensors, temperature sensors and a main control board, wherien an outer shell of the testing head is a cylinder, wind blows to the surface of the outer shell of the cylinder, the surface of the outer shell of the cylinder can bear regular pressure with different magnitudes, and the pressure reflects speeds and directionsof wind flows; and the pressure sensors are connected with a plurality of pressure holes formed in the side wall of an outer shell of the testing head, the pressure of wind borne by the outer shell of the cylinder is detected, and the main control board calculates a current wind speed and a current wind direction according to the pressure values, detected by means of the pressure sensors, corresponding to the pressure holes and the environment temperature detected by means of the temperature sensors. The wind speed and wind direction testing device does not need mechanical parts, and is sensitive in response, high in test precision and small in error.
Description
technical field [0001] The invention belongs to the technical field of wind speed and direction detection, and in particular relates to a wind speed and direction testing device and a testing method. Background technique [0002] Anemometers are widely used in wind energy, meteorology, industry, transportation, etc., and can provide guidance for the production of all walks of life, occupying an important position in modern detection technology. [0003] Most of the existing anemometers are mechanical, using the wind cup as the sensing element. Due to the inertia of the mechanical parts and possible wear and sticking, the anemometer is not sensitive enough, the test accuracy is low, and the error is large. Contents of the invention [0004] In view of this, the embodiment of the present invention provides a wind speed and wind direction testing device and testing method to solve the problem of insensitivity and testing accuracy caused by inertia and wear and sticking of mec...
