Calibration method and device for anemorumbometer in wind and sand environment

The invention discloses a calibration method and device for an anemorumbometer in a wind and sand environment, two sensors are installed on a fan, a main sensor is responsible for measuring the wind speed and the wind direction, and an auxiliary sensor is responsible for measuring the influence of wind belt sand grains on the main sensor; meanwhile, the auxiliary sensor is provided with a protection screen and a mounting bracket, so that most wind power is effectively blocked, and sand grains are allowed to impact the pressure sensor; besides, the calibration algorithm of the auxiliary sensor to the main sensor is designed, so that the measurement accuracy and reliability of the anemorumbometer adapting to a severe wind and sand environment are improved, reliable data support is provided for operation and control of a fan, the measurement precision and reliability of the anemorumbometer are improved, and the application range of the anemorumbometer is widened. The adaptive capacity of the draught fan in the s
