Structure state detection and damage assessment system with fiber optic sensing array and neural network signal processing techniques

摘要

The principle and structure of a structure state detection and damage assessment system are given. A novel fiberoptic sensing array and suitable neural network signal processing techniques are described. The experimental results on structural member of gypsum show that the system can monitor physical states of structures and can be developed into smart structures with potential applications in areas such as space aeronautics, ship and civil engineering, etc.
