Aiming at the accurate identification ofwind speed and direction in the natural environment

the wind speed anddirection twoparameter sensor detection system was designed by ultrasonicprinciple The ultrasonic wave isgenerated in the system and the ultrasonic transducer with frequency 213kHz isused The ultrasonic sensor uses theultrasonic phase difference method to measure the wind speed and direction The measurement principle and calculationmethod of the twodimensional phase difference method are elaborated The method is verified by Lissajouscurve Feasibility Replacing complex analog circuits with the samedigital chip in the system improves sensor integration The test results in the bellows show that thesignal is processed by the phasedetection circuit and compared with ZRQFplatinum resistance wire type wind speed sensor to verify the processing speedand accuracy The designed ultrasonicwind speed and direction test system in the gas flow direction detection andenvironment monitoring and other aspects have practical and effective detectionand environmental monitoring
