The principle of measurement of wind speed and direction using ultrasonic wave time difference method is introduced followed by related algorithms
the design of ultrasonic wave anemometer based on ARM+CPLD is described in details.In addition
an effective algorithm dealing with the average wind direction problems near 0°(360°)is proposed.An absolute wind speed measurement model is provided using a baroceptor for practical wind measurement applications.The designed ultrasonic wave anemometer has important reference application value in environmental monitoring and wind power generation.
