摘要
利用时差法超声波测风原理设计了风速风向测量系统,实现了对瞬时风速风向的精确测量,克服了传统测风仪测量精度不高和使用环境受限制等缺点。在硬件设计上,搭建了基于MSP430的硬件电路,通过对信号放大和滤波等处理,提高了系统的抗干扰能力,进一步保证了测量时差的精度。在软件设计中,通过编程实现了对超声波发射和接收控制以及数据的分析处理和显示。实验结果表明,该系统实现了对低空风场情况的精确测量和实时监控,达到了系统低功耗、高性能的设计目标,具有较高的实用价值和应用前景。
A wind measurement system which is designed by using the time difference method can measure the instantaneous wind exactly. Compared with the traditional wind measurement,it also has a higher precision without the use of space limitation. The hardware circuit that is designed based on MSP430 improves the ability of anti-interference and ensures the accuracy of time difference measurement by designing the circuits of signal amplification and wave filtering and so on. In the software, the control of sending and receiving ultrasonic, data analysis and processing are designed by programming. The experiment results show that the system which has high practical value and application prospect realizes the accurate measurement and real time monitoring for the low level wind field, and achieves the design goals of low power and high sensitivity.
