| Abstract: | By using Fiber Bragg Gratings(FBG) sensors as strain sensors and developing an effective algorithm of the real-time and in-situ loading recognition,an online load monitoring(OLM) system has been developed.The system was integrated into the software platform of a dynamic FBG wavelength demodulator(sm130-700,MOI) based on a graphical programming language,Labview 8.0,and then applied to a pterygoid cantilever to carry out the load recognition experiment.The experimental results indicate that the present OLM sy... |
