Description

Technical Field

[0001] The utility model relates to the technical field of wind speed calibration equipment, in particular to a meteorological on-site starting wind speed calibration device. Background Art

[0002] Meteorology refers to all physical phenomena in the atmosphere that occur in the sky. Meteorological information is used in agriculture, transportation, and the military. Agriculture needs to arrange sowing and harvesting according to weather forecasts, the transportation department needs to understand weather conditions to ensure safety, and the military also needs accurate meteorological information to formulate combat plans. In addition, meteorology is closely related to human health. Extreme weather can lead to the spread of disease and health problems.

[0003] Meteorological observation items include temperature, air pressure, humidity, wind direction and wind speed. These observation data are used to analyze and predict weather changes and help people arrange their lives and production activities reasonably. The anemometer is an instrument used to measure wind speed. The wind volume is calculated by measuring the flow rate of the wind. It consists of a fan blade and a tachometer. When the wind blows through the fan blade, the fan blade will rotate and generate an electrical signal. The tachometer will measure the frequency of this signal and convert it into wind speed. By measuring the wind speed and the area of ​​the fan blade, the wind volume can be calculated, which can help people better understand and grasp the wind conditions and make better decisions.

[0004] The function of the wind speed calibration device is to ensure the accuracy of wind speed measurement and improve work efficiency. Through the calibration device, the standard wind speed can be provided quickly and accurately, which is used to calibrate the gas flow velocity measuring instruments of anemometers and wind speed sensors to ensure that the measurement results of these devices are accurate and reliable. It plays an important role in ensuring measurement accuracy and improving work efficiency. It is an indispensable tool in wind speed measurement. However, in wind speed measurement, the airflow field inside the airflow generating device is not completely uniform, and there will be differences in wind speed and wind direction at different positions. At the same time, vibration will cause errors in sensor readings, resulting in low calibration accuracy. Utility Model Content
