Apparatus capable of measuring vector wind speed

The invention provides an apparatus capable of measuring a vector wind speed. The apparatus structurally comprises a base (1), a transverse-axis steering engine (2), a longitudinal-axis steering engine (3), an ultrasonic wave pulse generator (4), an ultrasonic wave receiver (5), a horizontal rotating shaft (6), a vertical rotating shaft (7) and a display screen (8). The internal circuit system of a sound wave vector wind speed measurement apparatus is composed of a processor MCU (9), an ultrasonic wave generator (10), an ultrasonic wave receiver (11), a longitudinal-axis steering engine (12), a temperature sensor (13), a lithium battery power management circuit (14) a display screen (15) and a transverse-axis steering engine (16). According to the invention, a wind speed in a triaxial direction is measured by reference to the speed of sound waves in air at different temperatures through a Doppler effect of the sound waves in flowing air, and a speed value and a direction of the vector wind speed are synthesiz
