Embodiment Construction

[0022] Such as figure 1 and as figure 2 As shown, an ultrasonic wind measuring instrument includes: a plurality of ultrasonic probes 10 , a processing circuit (not shown in the figure), and a housing 20 for accommodating the ultrasonic probes 10 and the processing circuit.

[0023] The casing 20 includes an emitting surface 211 and a reflecting surface 221 , which are arc surfaces respectively, and the emitting surface 211 and the reflecting surface 221 are arranged opposite and separated by a preset distance to form a space.

[0024] The ultrasonic probe includes a first ultrasonic probe and a second ultrasonic probe, the first ultrasonic probe and the second ultrasonic probe are distributed on the transmitting surface 211 or the reflecting surface 221, and the transmitting signal of the first ultrasonic probe passes through the reflecting surface 2211 and the reflecting surface 221 in space after being transmitted. The multiple reflections from the transmitting surface 211...

Abstract

The invention relates to an ultrasonic wind meter, comprising a plurality of ultrasonic probes, a processing circuit and a housing which accommodates the ultrasonic probes and the processing circuit. The housing comprises an emitting surface and a reflecting surface, both of which are cambered surfaces. The emitting surface and the reflecting surface are arranged opposite to each other at a preset interval to form a space. The ultrasonic probes comprise first ultrasonic probes and second ultrasonic probes, which are distributed on the emitting surface or the reflecting surface. Emission signals of the first ultrasonic probes are emitted, then are reflected for many times within the space by the reflecting surface and the emitting surface, and are received by the second ultrasonic probes. The processing circuit is connected with the ultrasonic probes and is used to obtain receive/transmit data of the ultrasonic probes and get measurement results about wind velocity and wind direction in accordance with the receive/transmit data. The preset distance between the emitting surface and the reflecting surface of the ultrasonic wind meter is small, so that the size of the ultrasonic wind meter is reduced.

Description

technical field [0001] The invention relates to the field of wind measuring instruments, in particular to an ultrasonic wind measuring instrument. Background technique [0002] Ultrasonic anemometer refers to a measuring sensor or measuring instrument that calculates wind speed and direction by sending ultrasonic pulses and measuring the time or frequency difference (Doppler frequency shift) at the receiving end. Ultrasonic wind measuring instruments are used in many technical fields, such as environmental detection, wind power generation, wind measuring towers and weather stations. Most of the existing ultrasonic anemometers have a diameter of more than 10 cm and are relatively large in size, which requires more resources to be consumed due to their large size. Contents of the invention [0003] Based on this, it is necessary to provide a small ultrasonic wind measuring instrument. [0004] An ultrasonic wind measuring instrument, comprising: a plurality of ultrasonic p...
