Abstract: According to the problem of measuring the wind speed and wind direction in a fast and accurate way,a 3D ultrasonic measuring system is designed by a high- precision time measuring chip TDC-GP21 and a SCM control chip MSP430F413. Three pairs of ultrasonic transducers are used to constitute the 3D arrays and the time difference method is used for measurement. In this paper,the overall structure of 3D ultrasonic measuring system,the ultrasonic driving circuit and the ultrasonic receiving circuit ar... More
