This paper briefly describes the advantages of the time difference ultrasonic wind speed measurement method, and based on the two-dimensional V-structure ultrasonic measurement principle of time difference method, a two-dimensional ultrasonic wind speed measurement system based on STM32F103ZET6 is built. Compared with traditional wind measurement systems, the design introduces the Hilbert Huang Transform algorithm to process the measurement data, which can ensure the accuracy of the wind speed measurement. The experimental results show that the design has strong adaptability and can achieve high precision wind speed measurement. It has high reference value and practical significance in the observation of complex meteorological environment such as air-sea interface.
