Problems solved by technology

At present, the measurement method used by the ultrasonic wind measurement system of automatic weather stations is mostly the time difference method. The ultrasonic wind measurement system based on the time difference measurement method has certain requirements for the distance between the ultrasonic transducers that send and receive ultrasonic signals. The smaller the distance , the shorter the time interval between driving the ultrasonic transducer to transmit the ultrasonic signal and receiving the ultrasonic echo signal, the greater the measurement error, which directly affects the measurement performance of the entire wind measurement system
In order to ensure the measurement accuracy and stability of the overall wind measurement system, the relatively mature ultrasonic wind measurement system on the market currently uses the time difference measurement method, and the sound path is basically above 100mm. It is difficult to realize the miniaturization of the wind measurement system

Abstract

The invention discloses an ultrasonic wind finding system and method. The system is composed of ultrasonic transducer probes, a circuit board, a pedestal, and a reflection plane. The ultrasonic transducer probes are used for transmitting and receiving pulse signals having set lobe widths; each two ultrasonic transducer probes are opposite to each other and form one group; a connecting line between each two ultrasonic transducer probes opposite to each other is marked as a connecting wire; and at least two groups of connecting wires in the system are perpendicular to each other. An ultrasonic wave emitted by the ultrasonic transducer probe in each group is reflected by the reflection plane and then can be received by the other ultrasonic transducer probe in the same group as the ultrasonic transducer probe and only can be received by the other ultrasonic transducer probe in the same group as the ultrasonic transducer probe. Using the method and system provided by the invention, accuracy of a measuring result is guaranteed and miniaturization of the wind finding system is realized.

Description

technical field [0001] The invention relates to the field of wind speed measurement, in particular to an ultrasonic wind measurement system and method. Background technique [0002] In order to meet the development needs of my country's ocean observation, it is urgent to develop a small integrated automatic weather station. At present, the measurement method used by the ultrasonic wind measurement system of automatic weather stations is mostly the time difference method. The ultrasonic wind measurement system based on the time difference measurement method has certain requirements for the distance between the ultrasonic transducers that send and receive ultrasonic signals. The smaller the distance , the shorter the time interval between driving the ultrasonic transducer to transmit the ultrasonic signal and receiving the ultrasonic echo signal, the greater the measurement error, which directly affects the measurement performance of the entire wind measurement system. In ord...
