Problems solved by technology

[0003] In a current ultrasonic wind measuring instrument, two sets of ultrasonic probes can be used to vertically oppose the structure as a cross-intersecting array, but this structure is affected by the shadow effect caused by Karman vortex street and other turbulence when the air flows around the transducer and the pillar Serious, resulting in inaccurate measurement results; In addition, in another wind measuring device, when measuring large wind speeds between the transmitting board surface and the signal reflecting board surface where the ultrasonic probe is located, it is seriously affected by turbulence, and the wind speed has a large difference in the longitudinal section gradient wind speed between the two boards. It will also make the measurement results inaccurate

Abstract

The present invention provides an ultrasonic transducer wind measurement array and a wind measurement method thereof. The wind measurement array comprises a main housing, a connection arm supporting the main housing and a wind measurement mechanism arranged on the main housing; the main housing is internally provided with a wind measurement circuit; and the wind measurement mechanism includes an ultrasonic transducer with a preset quantity, installation fixing joints and a column arm, wherein the ultrasonic transducer with the preset quantity includes three bijection sets, each bijection set is packaged in each installation fixing joint, each installation fixing joint is connected with the main housing through the column arm, and the three installation fixing joints are located on the same horizontal plane and form an equilateral triangle. The ultrasonic transducer wind measurement array and the wind measurement method thereof can improve the wind measurement precision.

Description

technical field [0001] The invention relates to the technical field of meteorological element measurement, in particular to an ultrasonic transducer wind measuring array and a wind measuring method thereof. Background technique [0002] Wind speed measuring instruments are used in a wide range of fields, such as wind disaster warning, wind power generation, environmental monitoring, navigation and aviation, military activities, etc. Ultrasonic wind measurement has low loss, wide range, fast response, and high precision. It can overcome the defects of mechanical wind measurement hysteresis and low precision, and will gradually replace traditional mechanical wind measurement equipment. [0003] In a current ultrasonic wind measuring instrument, two sets of ultrasonic probes can be used to vertically oppose the structure as a cross-intersecting array, but this structure is affected by the shadow effect caused by Karman vortex street and other turbulence when the air flows aroun...
