Embodiment Construction

[0025] The present invention will be further described in conjunction with the accompanying drawings and specific embodiments.

[0026] A method for measuring wind speed and direction, comprising the following steps:

[0027] S1: if figure 1 and figure 2 As shown, two pairs of ultrasonic transducers 51, 53 and 52, 54 with transmitting and receiving functions perpendicular to each other and in the same plane are set, and the straight line formed by one pair of ultrasonic transducers 52, 54 is set as the X axis, The straight line formed by another pair of ultrasonic transducers 51 and 53 is the Y axis, and an ultrasonic reflection plate 4 is arranged above the two pairs of ultrasonic transducers.

[0028] S2: respectively measure and obtain the propagation time t of ultrasonic waves emitted by the transducer 54 and reflected by the ultrasonic reflector 4 to the transducer 52 x1 , the ultrasonic wave is emitted by the transducer 52 and is reflected by the ultrasonic wave refl...

Abstract

The invention relates to a wind speed and wind direction measurement method. The method comprises the following steps of firstly, arranging two pairs of ultrasonic transducers which are vertical to each other, are located in a same plane and possess a transmit-receive function, and arranging one ultrasonic reflection plate above the two pairs of ultrasonic transducers; secondly, measuring and acquiring propagation time of an ultrasonic wave which is received by the two transducers in each transducer pair from opposite sides through the ultrasonic reflection plate; and then, according to the measured ultrasonic wave propagation time and a spacing of the two opposite transducers in the corresponding ultrasonic transducer pair, acquiring a corresponding ultrasonic wave propagation speed; and finally, according to the corresponding ultrasonic wave propagation speed, calculating a wind speed and a wind direction. By using the method of the invention, wind speed and wind direction measurement does not influenced by an environment; measurement precision is high and a system cost is low.

Description

technical field [0001] The invention relates to the field of wind speed and direction measurement, in particular to a method for measuring ultrasonic wind speed and direction. Background technique [0002] Because the mechanical wind speed and direction instrument is not easy to carry, the life of the machine is short and the error is large, therefore, the wind speed and direction instrument using ultrasonic waves is more and more popular among users. [0003] The key technology of ultrasonic method to measure wind speed and direction is to measure the propagation speed of ultrasonic waves between two ultrasonic transducers, that is, the accurate measurement of the propagation time of ultrasonic waves from the transmitting transducer to the receiving transducer. The methods currently on the market for ultrasonic measurement of propagation time are: [0004] A: The method of finding the maximum peak zero-crossing point: After the transducer a transmits a certain number of ul...
