Abstract

The present invention is applicable to the technical field of wind speed and direction detection, and provides a wind speed and direction testing device and a testing method. The wind speed and direction testing device includes: a test head, a support rod, at least two strain gauge sensors, a temperature sensor, a barometer and a main control plate. Wherein, the test head is a cylinder, and when the wind blows to the surface of the test head of the cylinder, the test head of the cylinder will produce regular strain, and the strain reflects the speed and direction of the wind flow. At least two strain gauge sensors are set on the test head to detect the strain on the cylinder test head, and the main control board can determine the current wind speed and wind direction according to the strain, current temperature and current pressure detected by at least two strain gauge sensors . The device does not need to be equipped with mechanical parts, and has the advantages of sensitive response, high testing precision and small 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...
