High-accuracy solid-state wind speed and direction measuring device

The utility model relates to an instrument for measuring wind speed and wind direction, in particular to a high-accuracy solid-state wind speed and direction measuring device, which structurally comprises two pairs of ultrasonic wave sensors distributed on the same plane in orthogonal mode, wherein each pair of ultrasonic wave sensor transmits and receives ultrasonic wave signals with each other, a signal transmitting end of each ultrasonic wave sensor is connected with a high-pressure pulse signal generator through a transmission signal simulation switch, and a signal receiving end of each ultrasonic wave sensor is connected with a simulation processing circuit through a receiving signal simulation switch. The high-accuracy solid-state wind speed and direction measuring device adopts a solid state sensor method for measuring, has no requirement for starting up wind speed, has no measuring inertia and is long in service life, simultaneously high in measuring accuracy and fast in measuring.
