Abstract

An ultrasonic wind measuring device and an ultrasonic wind measuring method which are disclosed by the invention are used for measuring the wind speed and wind direction in an environment by making use of ultrasonic transmission characteristics. The ultrasonic wind measuring device comprises an ultrasonic transducer group used for forming ultrasonic resonance in a cavity accommodating the ultrasonic transducer group, a transmitting module used for driving any ultrasonic transducer in the ultrasonic transducer group to transmit an ultrasonic waveform, a transmitting and receiving conversion module used for performing link switching on the ultrasonic transducer group according to a preset control instruction, a receiving module used for receiving the ultrasonic waveform, an acquisition module used for acquiring original data of ultrasonic waveform transmitting and receiving, an FPGA processing chip used for processing the original data to obtain time data, and a processor control module used for performing calculation to acquire the current wind speed and wind direction according to the time data. The invention adopts ultrasonic transmission which is short-distance, the measurement accuracy is ensured, and the device is small in size and convenient to install.

Description

technical field [0001] The present invention relates to the technical field of ultrasonic sensing, and more specifically, to an ultrasonic wind measuring device and method. Background technique [0002] With the development of technology, the traditional mechanical (triangular wind cup, wind vane) anemometers are not accurate enough in measurement, and are prone to problems such as mechanical wear and wind and sand adhesion, resulting in measurement errors. Therefore, devices using ultrasonic and other sensing technologies to measure wind speed and direction have emerged one after another. However, the current ultrasonic wind speed and wind direction equipment generally uses four ultrasonic transducers for measurement, which has problems such as large equipment volume and easy interference. [0003] Therefore, there are problems in the prior art that the measurement equipment is large in size, low in measurement accuracy and poor in adaptability to the external environment....
