Method and device for measuring wind speed

The invention provides a method and a device for measuring a wind speed, relating to the testing and measuring filed and solving the problem of greater wind speed measuring error in the prior art. The method comprises the following steps of: acquiring the current AD value of the wind speed; respectively taking the logarithms of a calibration AD value, a calibration wind speed value and a current AD value; and acquiring the wind speed by the taken logarithms of the calibration AD value, the calibration wind speed value and the current AD value.
