An optimal placement of FBG sensor network based on probability model

摘要

Optimal placement of sensor network determine the performance and cost of sensor network, and sensor range is a key factor of optimal placement. Unlike the traditional sensor, FBG sensor have different detecting probe length in difference angles, due to the sensitivity of FBG in axial direction is much better than the other directions. Sensor layout angle is not discussed in previous studies about FBG sensor network. The layout angle of sensor considered in placement can greatly impact the performance of FBG sensor network. The paper propose a detective model for FBG sensor which fit it is feature based on probability model, and verified the correctness of it by experiment, then particle swarm optimization is used for optimize the placement of FBG sensor network. Finally, the paper compare this optimization result with method which not consider the layout angle of sensor, and that indicates the performance of sensor network is greatly improved by add the layout angle to placement.
