资料介绍

风对飞机的起落和船的航行航线影响很大。超声波测风技术是基于向量分析法。文章对超声波风速测量的基本原理和实现方法进行了详细阐述,通过吸收国内外先进超声测量技术,设计了一种基于传统时差法的超声波测风速风向的电路。采用高性能、具有较小温度一声速系数和声阻抗的超声波换能器,正三角形安装方式。设计合理实用,具有高的精度与稳定性。传感器结构比传统的十字型有突出的优点。

The wind has a great effect on aircraft landing and the navigational routes of boats. Ultrasonic wind measuring tech- nology is based on the analysis of the vector. This article describes the fundamental principle and achieving methods of ultrasonic wind speed measurement in detail. Absorbing domestic and foreign advanced ultrasonic measuring technology, we designed an ap- proach to measure wind speed and direction by ultrasonic based on traditional method of time difference. This design used high per- formance, a relatively small coefficient of temperature-speed and acoustic impedance ultrasonic transducers. They were installed in triangle. It is reasonable and practical, and has high accuracy and stability. The structure of the sensor has highlight advantage...
