The present invention relates to a self-generated phase difference-based continuous wave ultrasonic anemovane. To this end, the anemovane of the present invention comprises: a lower base arranged on an installation surface; a plurality of supports vertically arranged along an outer circumferential surface of an upper surface of the lower base; an upper base arranged to be separated to an upper side of the lower base, and fixated to be supported by the support; a plurality of rotating wings inserted between the lower base and the upper base, arranged in the plural inside the support, and rotating to be coupled to a rotating axis of the center; a self-generating unit provided inside the lower base, and generating electric energy by receiving rotation power by rotation of the rotating axis; a power control unit for charging a battery with the electric energy generated by the self-generating unit or converting the electric energy into certain voltage; and an ultrasonic measurement unit installed to be fixated in an upper surface of the upper base, and measuring wind direction information and wind speed information by an ultrasonic wave. |
