Research on Temperature Compensation of Fiber Bragg Grating Sensing System for Wind Turbine Blade Load Monitoring
摘要
Abstract
Based on the application background of wind turbine blade load monitoring system,a fiber Bragg grating sensing system based on the principle of fiber Bragg grating sensing and adjustable MEMS mirror filtering method is designed and developed.Based on the tem-perature characteristics of fiber Bragg grating sensors,the sensing system can achieve automatic strain wavelength demodulation and tem-perature compensation function for the selected fiber Bragg grating strain sensors by selecting the fiber Bragg grating strain sensor and combining it with the control board program algorithm design.The demodulation accuracy,temperature stability,and temperature compen-sation performance of the demodulation system are tested in the experiment.The temperature wavelength demodulation accuracy and strain wavelength demodulation accuracy are both around 2 pm.In the temperature stability test,within the temperature range of-20℃to 65℃,the output wavelength of the demodulation system changes within 22 pm.In the temperature compensation performance test,within the temperature range of-20℃to 65℃,the output wavelength of the demodulation system changes within 50 pm.关键词
