Abstract

The invention discloses a three-dimensional ultrasonic wind speed and wind direction detection system and a measurement method. The detection system comprises a mounting base, a plurality of measurement arms, ultrasonic probes and a control and processing circuit board, wherein the quantity of the ultrasonic probes is equal to that of the measurement arms; one measurement arm is fixed to the center of the top surface of the mounting base, and the remaining measurement arms are arranged on the circumference of the top surface of the mounting base in a surrounding mode; the ultrasonic probes are arranged at the top ends of the measurement arms; the control and processing circuit board is arranged in the mounting base, is connected with the ultrasonic probes and controls the ultrasonic probes to work. The measurement method comprises the first step that all modules are initialized through a control and data processing module; the second step that a wind speed component V1 can be obtained according to transmission time t1 and t4 by the adoption of an indirect time difference method; the third step that three-dimensional wind speed values and wind direction values are obtained; the fourth step that real-time three-dimensional wind speed and wind direction are obtained. The three-dimensional ultrasonic wind speed and wind direction detection system and the measurement method have the advantages that received signals are stable; the instrument cost is greatly lowered; measurement accuracy is high, and real-time performance is good.

Description

technical field [0001] The invention relates to a wind speed and direction detection system and a measurement method, in particular to a three-dimensional ultrasonic wind speed and direction detection system and measurement method.
