Abstract

The invention discloses a multi-input multi-output array type ultrasound anemometry system and method. The multi-input multi-output array type ultrasound anemometry system comprises an installation seat, a plurality of ultrasound sensors, a fixing supporting frame, a reflection hemisphere and a control and processing circuit board, wherein the multiple ultrasound sensors are arranged on the top surface of the installation seat, the lower end of the fixing supporting frame is fixed to the installation seat, and the reflection hemisphere is arranged at the upper end of the fixing supporting frame. The multi-input multi-output array type ultrasound anemometry method includes the following steps that firstly, after the system is powered on, a data processing module carries out processing; secondly, sliding average processing is carried out; thirdly, cross-correlation calculation is carried out; fourthly, any ultrasound sensor on the x axis, any ultrasound sensor on the y axis and the reflection hemisphere can form an anemometry surface; fifthly, real-time wind speed and wind direction can be obtained by circulating the first step to the fourth step. The multi-input multi-output array type ultrasound anemometry system and method have the advantages that eddies are avoided, receiving signals are stable, and the anemometry accuracy of the wind speed and wind direction is further improved.

Description

technical field [0001] The invention relates to an ultrasonic wind measurement system and a measurement method, in particular to a multi-input multi-output array type ultrasonic wind measurement system and a measurement method. Background technique [0002] At present, compared with the traditional mechanical anemometer, the advantages of the ultrasonic wind measurement system are: no start-up wind speed limit, strong environmental adaptability, adaptable to all-weather weather, no mechanical wear, not easy to corrode, long service life, high precision High, intelligent, high reliability, simple installation, easy maintenance and calibration, etc.; it can not only meet the needs of meteorological wind measurement in the military field, but also has many uses in civilian use, such as climate meteorology, urban environmental monitoring, wind power generation It has very good application prospects in meteorological monitoring, bridges and tunnels, automobile highways, navigatio...
