Abstract

The invention discloses a reflective ultrasonic anemoscope and a measuring method thereof. The reflective ultrasonic anemoscope comprises four parts, namely a probe mounting seat (1), ultrasonic probes (21, 22, 23 and 24), a bracket (3) and a reflecting surface (4), wherein the four ultrasonic probes (21, 22, 23 and 24) are fixedly arranged on the probe mounting seat (1), are divided into two groups and are arranged on two orthogonal axes; and various ultrasonic probes (21, 22, 23 and 24) transmit ultrasonic signals in turn, and opposite ultrasonic probes (21, 22, 23 and 24) receive signals reflected by the reflecting surface (4). A wind speed value and a wind direction value are solved by a vector composition method. The reflective ultrasonic anemoscope eliminates influence on measurement due to a difficultly fixed measuring structure and great change of signal intensity along with the wind speed.

Description

technical field [0001] The invention relates to the technical field of wind speed and wind direction measurement, in particular to a reflective ultrasonic anemometer and a measuring method thereof. Background technique [0002] In the fields of ship navigation, wind power generation, weather observation and forecasting, and environmental measurement of sports venues, etc., wind measurement requirements are involved, which makes anemometers widely used. [0003] Commonly used anemometers include mechanical anemometers, dynamic pressure anemometers, and hot-wire anemometers. Among them, the mechanical anemometer uses the rotation of mechanical parts to sense the wind speed, and combines it with the wind vane to obtain the wind direction. This method is simple and reliable, but because its measuring part has mechanical moving parts, it is easy to wear and tear under long-term exposure to the outdoor working environment, its life is limited, and its maintenance cost is high. T...
