Airflow parameter measuring device and method

The invention relates to an airflow parameter measuring device and method. The airflow parameter measuring device comprises a processor, an ultrasonic transmitting head serving as a center and at least three receiving ends which are annularly arranged, surround the center and have an ultrasonic receiving function. On one hand, the receiving end with the ultrasonic wave receiving function is adopted, the receiving end is sensitive in response to weak airflow such as breeze and the like, airflow parameters in the breeze and strong wind range can be measured, the measurement range is large, the measurement precision is high, and measurement can be conducted in the low-temperature environment and the rainy and snowy weather environment; in addition, a receiving end with an ultrasonic wave receiving function, such as a silicon microphone, is adopted, and the cost and the size can be greatly reduced, so that the airflow parameter measuring device disclosed by the invention greatly reduces the cost and the size unde
