| 摘要 |
The present invention relates to an anemovane using a piezoelectric element, including a semispherical or spherical body portion (10); multiple cantilever type measuring units (20) that are disposed to radially protrude lengthwise on an outer circumferential surface of the body portion (10), have the piezoelectric element, generate voltage while being elastically deformed due to wind pressure, and output electrical signals according to the generated voltage; and a control unit (30) that periodically collects the signals which are respectively output from the multiple measuring units (20) and calculate wind direction and speed based on the output values of the collected signals. According to the present invention, the wind direction and speed can be three-dimensionally measured at the same time, the multiple measuring units are provided for information collection, and the precision of the measurement and the accuracy of the measurement result increase as the flow of wind is not interrupted. |
