Study On The Distributed Optical Fiber Intelligent Health Monitoring System Based On Multi-agent Coordination

Along with the increasingly complex and diverse of aircraft structure and size scale, traditionalaviation structural health monitoring is facing a number of key scientific problems, which are to besolved under complex loading conditions in the filed of aerospace engineering. As a new researchresult of the field in artificial intelligence, the main idea of multi-agent coordination technology is toaccomplish the complex problem by multiple agents interacting together more than by a single agent,whose capacity and knowledge are limited. The multi-agent technology is applied in the filed ofstructural health monitoring on both theoretical and experimental aspects in this paper. A large size ofaviation aluminum is used as the monitoring object and the fiber optic intelligent health monitoringsystem is built based on multi-agent technology. The feasibility and reliability of the multi-agentsystem are studied and discussed, and are also verified by both simulation and experiment. The maincontent of the paper includes the following sections.Firstly, the research status at home and abroad of multi-agent technology and its application instructural health monitoring is introduced, the background and development of submarine cable routeand damage detection are briefly summarized as well. The relevant knowledge and working principleof agent and multi-agent theory are described, and the various agents in multi-agent structural healthmonitoring system are defined in function.Secondly, the framework of a fiber optic intelligent health monitoring system based onmulti-agent technology is established. The static loading damage identification in multi-regionalmonitoring, the focused identification of partial damage based on net collaboration and the netself-diagnosis/self–healing based on light switch are theoretical analyzed and designed for the sake ofthe feasibility and reliability of the system. The system is preliminary tested from the point ofsimulation and the theoretical basis is provided for the paper.Thirdly, a fiber optic intelligent health monitoring system based on multi-agent for experiment isdesigned and established, according to the content of this paper. The experimental program is plannedto conduct the related experiments. The experiment verification of the feasibility and reliability of themulti-agent system is completed and the experimental results are consistent with the simulationresults.Finally, a submarine cable damage detection system based on the active AC electromagnetictheory is additionally studied. A new antenna array is designed. The array parameters are analyzed from the point of numerical simulation and a simple experiment is used to verify the antenna array.The experimental results show that the new antenna array can be effectively applied in the field ofsubmarine cable route and damage detection.
