Research On Multi-Agent System For Structural Health Monitoring

In structural health monitoring system, we will acquire the damage information by the sensors embedded in the structure and make a judgment to safety status of the structure. It is propitious to restrain damage, decrease damage and increase the safety of the structure. This is significant study and proper application foreground not only in aeronautics and astronautics but also in national defense and so on. In the text, a new technology is brought frowaord which is about structural health monitoring based on multi-agent system aiming to giant engineering structural. Its basic idea is changing center processor instead of distributed processor. In this processor, the structural health monitoring system will be managed by multi-agent technology. Thus, the system function, dependability and sensitivity will be increased, while the practicality of structural health monitoring in giant engineering will be promoted. In this study, the monitoring objects are the load and impact in structural of fiberglass complex by adopting PZT and resistance wires as sensors. Using the method of region value will orient impulsion. Classical mode-identify is managed for load orientation, and a little resistance wires are used. The mode and application of data acquirement is researched profoundly. The external control trigger circuit is designed. And with the help of multi-agent system, the sensors will be selected in reason for managing signals and realizing inspection for two objects corresponds. The network contains a great deal of different sensors that are provided with special and limited functions in distributed structural health monitoring system. Single sensor cannot acquire comprehensive information unless coordinate in the process of work and data communication. Multi-agent system will improve the function of the system and help to make a right monitoring conclusion. In this study, it is easy to correspond piezoelectricity and resistance wires. But this study shall make a good base for the more application of multi-agent system.
