Distributed Grating Sensor Stress Data Acquisition and Management System

This paper points out the measuring principle of grating sensor for stress change. Firstly, the sensitivity of FBG wavelength to temperature or strain is utilized, then the corresponding waveform is drawn, and then the desired physical quantity is calculated through the specified formula, so as to realize the detection of the environmental parameters of FBG. At present, the data acquisition of remote strain measurement has been realized, but the data returned is the wavelength data which has changed, aiming at the needs of industry applications. Wavelength data are displayed with digital scales, and the data are replayed and analyzed. Finally, the expected goal is achieved.
