A novel wind measuring system was proposed. Its wind sensing component has a special structure with cylinder shape, which converts wind vector into pressure vector. The wind parameters were achieved by measunng pressure vector. In the sensing component,three pull-pressure sensors were symmetrically placed in Y shape. Three-way signals were achieved via sensors and were analyzed by DSP system to obtain Lhe wind speed and direction. It's verified by the experiment that,the novel system has good accuracy , higher stability compared to the cup anemometer, and lower cost compared to the ultrasonic anemometer. Thus it has wide prospect to be applied in the field of wind power generation.%提出了一种新型风速风向仪,它采用外形为圆柱形的特殊结构的测风感应部件,将风矢量转换为力矢量,通过力矢量的测量得到风速风向参数.这种风速风向仪内部放置3个成Y型120°对称分布的拉压力传感器,测出传感器因受力而感应的3路电信号,送至DSP处理电路,由所测力矢量的大小与方向,解算实际对应风速风向.实验结果表明:系统精度较高,比有旋转部件的机械式测风仪可靠性好,比超声测风仪成本低,在风电领域有广泛的应用前景.
