资料介绍

超声波风速风向仪由于其精度高、反应速度快等诸多优势,具有广泛的应用.文中针对基于时差法超声风速风向检测系统对处理器配置要求高、接收信号易受干扰等特点,设计了系统的超声波收发电路、隔离电路、放大滤波电路及峰值检测电路.实验测试表明,系统稳定性好,检波信号峰值识别度高,极大地方便了后续分析处理,具有一定实用参考价值,且系统具有成本优势.

Ultrasonic anemometer has wide application with the advantage of high precision,fast response speed and so on.Ultrasonic anemometer based on time difference usually require fast processor with high performance,and the receiving signal is easily interfered.In view of the above characteristics,ultrasonic transmit-receive circuit,isolation circuit,amplification and filttration circuit and peak detection circuit are designed in the system.The experiment results show that the system has good operation stability,and the peak of envelope signal is well recognized,which greatly facilitates the subsequent analyses,and it is valuable in practice.Besides,the system has cost effective advantages.
