Research on the design and optimization of wireless IoT underground sensor network based on optical fiber communication
A optical fiber sensing Internet of Things(IoT)data detection method based on a new type of fiber grating(FBG)packaging was proposed to address the problems of low accuracy and high energy consumption in traditional underground data monitoring.A sensor module for simultaneously testing strain and temperature has been designed,a new FBG packaging structure has been developed,and an optical fiber stress monitoring distribution network conforming to the roadway structure has been built.Through calculation based on cross-correlation difference,it has been optimized to eliminate vibration and noise.The test results show that the monitoring data from this method is consistent with the actual values and can effectively reduce energy consumption in the process of IoT data monitoring.The method has strong adaptability in complex underground environments.
