[0028] Among them, the heating components include a temperature sensor 5, an electric heating coil 6 and a controller 8. The temperature sensor 5 is fixedly installed on the top of the rotating base 2, the electric heating coil 6 is fixedly installed on the top of the rotating base 2, and the controller 8 is fixedly installed on the inner wall of the rotating base 2.

The controller 8 can use a single-chip microcomputer with a model of STC89C51. A wire hole is provided on the top of the rotating base 2 to facilitate the passage of the wire. When the temperature sensor 5 detects that the external temperature is lower than 0°C, the controller 8 controls the electric heating coil 6 to heat. The heating temperature can be set between 30 and 60 degrees, which can effectively melt the ice connected between the rotating base 2 and the rotating rod 3, and can effectively ensure the normal rotation of the wind cup 301.

Within the wind speed measurement range, the wind speed and the pulse frequency have a certain linear relationship, and the wind speed can be calculated based on this.
