To solve the detection difficulties in wind direction and wind speed sensors in regional automatic meteorological stations,a new-type portable wind direction and wind speed sensor detector is developed.When working by programming with the software of the upper computer and the single chip microcomputer to accurately position the step motor,the instrument realized the functions of intelligent detection and control,then compared the output values of the sensor with the standard values of the stepping motor,further to accurately control the rotation angle of the wind direction sensor or the rotation speed of the wind speed sensor,and finally achieve the purpose of automatic measuring performances of wind direction and wind speed sensors.Compared with the existing detection methods,the results show that the accuracy of this detector is higher and its stability is better.This detector is small in volume,light in weight,simple in operation and easy to carry,which integrates the functions of wind direction and wind speed detection and can effectively solve the field detection problem for regional automatic meteorological stations.
