英文摘要： For improving the predicting accuracy and self-diagnosis/self-repairing ability of the optical fiber structural health monitoring system, a distributed optical fiber intelligent integrated monitoring system based on multi-agent cooperative mechanism for typical aerospace structure is proposed in this project, and some typical loading cases are considered for the complex mechnical structure to verify the performance of the intelligent monitoring system. The key scientific problems which the optical fiber intelligent structural health monitoring system is confronted with，such as large size, complex structure and loading types are expected to be solved. The optimal placement and topology of the optical fiber sensor network are researched in the project. A distributed optical fiber intelligent integrated monitoring system which is composed of optical fiber sensing agents, signal processing agents, intelligent assessment agents, optical fiber sensor performance self-diagnosis/self-repairing agents and system cooperative agents is constructed. Depending on the cooperation and coordination mechanisms between each agent, the health status of the integrated structure is monitored, the optical fiber sensor in the sensor agents is detected, and the self-diagnosis/self-repairing ability of the local disabled network is also
