摘要:

传统的机械式风速测量仪受到诸多因素的影响和限制,已无法满足现今测量领域的指标。而使用超声波作为测量手段可以有效地提高测量精度、减少测量误差、降低功耗。系统采用MSP430作为处理核心,利用超声波的特性,使用超声波传感器,实现对空气中风速的测量,并利用无线通信ZigBee技术实现通信交互。通过分析得出文中装置测量精准、出风速度越大,测量越准确。

关键词: 风速测量, MSP430, 超声波传感器, ZigBee

Abstract:

By many factors,traditional mechanical anemometer have been unable to meet the target currently.The use of ultrasound to measure wind speed can effectively improve the measurement accuracy,reduce errors and power consumption.The system uses MSP430 as its processing core,and takes advantage of ultrasonic properties and ultrasonic sensors to achieve the measurement of wind velocity,and realize interactive communication using the technology of ZigBee.Analysis shows that the system proposed in the article is accurate in measurement,with better accuracy at higher wind speed.

Key words: wind speed measurement;MSP430;ultrasonic sensors;ZigBee
