New Digital Anti-Interference Wind Speed Measuring Instrument

The working principle of the wind speed sensor is as follows: the sensing element of the wind speed sensor is a three cup rotary frame, and the signal conversion circuit is a Hall switch circuit. Under the action of horizontal wind, the wind cup group rotates and drives the magnetic rod disk to rotate through the main shaft. The 36 magnets on the wind cup group form 18 small magnetic fields. Each revolution of the wind cup group induces 18 pulse signals in the Hall switch circuit, and its frequency increases linearly with the increase of wind speed. The calibration equation is: V=0.1F (V: wind speed, unit: m/s; F: pulse frequency, unit: Hz).

As a natural phenomenon, wind is one of the most important factors affecting climate change. It also contains enormous energy that can have a significant impact on human activities. More and more attention is being paid to the observation and research of wind parameters around the world. The wind direction and wind speed meter is used to measure the local wind direction and speed. The measured instantaneous wind direction and speed can be calculated and processed to output instantaneous wind speed and direction value, average wind speed and direction value, maximum wind speed, maximum wind speed, and other data.
