Background
In ancient times, people knew the use of wind energy. Zhuge Liang used the direction of the wind to burn the wall with the east wind. If the wind speed and direction can be measured, the wind can be used more effectively. Modern society develops with the advancement of science and technology. The wind vane anemometer, which is used to measure wind speed and direction, has also been widely used in meteorological monitoring.
Wind speed sensor
The wind speed sensor is a sensor that can continuously measure wind speed and air volume. The traditional three wind cup structure is adopted. It consists of three carbon fiber wind cups and a cup holder. The wind cup is made of ABS carbon fiber composite material, which has high strength and strong wind resistance. The hollow cup shells are fixed on three-pointed star brackets that are 120° to each other or cross-shaped brackets that are 90° to each other. The concave surface of the cup is arranged in one direction. The entire cross-arm frame is fixed on the vertical shaft. It has the advantages of large range, good linearity, strong resistance to lightning strikes, stable and reliable, and convenient observation.
Wind direction sensor
The main body of the wind direction sensor adopts the mechanical structure of the wind vane. It can measure the near-ground wind direction in the outdoor environment. Detect and perceive external wind direction information through the rotation of the wind direction arrow. And transmit it to the coaxial code disc, and output the corresponding wind direction value at the same time. When the wind blows to the tail of the vane, the arrow of the vane will point in the direction of the wind. It has the characteristics of strong anti-corrosion and strong anti-interference ability.
The importance of wind vane anemometer
It is convenient to observe weather, and wind vane anemometer is needed to measure wind speed and direction. Marine storm warning: The wind direction change data provided by the marine meteorological warning system is one of the important parameters for predicting the coverage and “operation” trajectory of typhoons. Marine meteorological warning system is one of the important applications of wind direction sensors in the field of meteorology. In deserts and plateau areas, we need to pay attention to changes in air velocity and wind direction. In order to master more meteorological data. Therefore, measuring wind speed and direction is very important for meteorology.
