Abstract

The invention discloses a multi-input multi-output array type ultrasonic wind measurement system and a measurement method. The wind measurement system includes a mounting seat, several ultrasonic sensors, a fixed bracket, a reflecting hemisphere and a control and processing circuit board, wherein several ultrasonic sensors Set on the top surface of the mounting base, the lower end of the fixing bracket is fixed on the mounting base, and the reflective hemisphere is set on the upper end of the fixing bracket. The specific method is as follows: first step, after the system is powered on, process it in the data processing module; second The first step is to perform sliding average processing; the third step is to perform cross-correlation calculations respectively; the fourth step is to form a measurement surface with any ultrasonic sensor on the x-axis, any ultrasonic sensor on the y-axis and the reflective hemisphere; the fifth step is to Real-time wind speed and wind direction can be obtained by performing the first step to the fourth step cyclically, with beneficial effects: no eddy current is formed, and the received signal is stable; the accuracy of wind speed and wind direction measurement 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...
