Method and apparatus for controlling air-blowing angle of fan on basis of human body orientation

Abstract

A method and apparatus for controlling the air-blowing angle of a fan on the basis of human body orientation, which are applied to a fan provided with a millimeter-wave radar unit and a sound source localization unit. Two modes, namely, a single-person sensing mode and a multi-person sensing mode, are designed, and a compensation and error correction mechanism is added for the multi-person sensing mode, such that the requirements of a user in different scenarios are satisfied, and the problem of a defective detection result from the millimeter-wave radar unit is also solved. In addition, the combination of the sound source localization technology and the millimeter-wave radar detection technology realizes fine adjustment of the air-blowing angle of the fan, thereby ensuring the accuracy of the air-blowing angle.
