Abstract: In order to realize wind field multipoint and remote sensing,make it convenient to monitor wind speed and set up the internet of thing of wind field velocity,an all-fiber wind velocity sensor fabric was introduced with a wind-cup to modulate fiber Bragg grating wavelength,so that the wind velocity can be obtained based on the wavelength changing frequency.Design scheme was described in detail.Fabrication process of the probe was introduced emphatically and some experimental data were also presented.The results show that the system works stably and reliably.The system can achieve a location precision of 0.16m/s and this system is very suitable for large wind power generation in consideration of its large-capacity.
