To solve the problem faced when monitoring the large practical structures,a multi-Agent system for monitoring the large aluminium plate was developed.
The whole system can choose strain gauge sensor,the fiber sensor and PZT sensor automatically,self-organize the sensor network and realize the typical three monitoring instances including the localization of acoustic emission source,bolt loosing and strain distribution monitoring.As one of the basis work for the implementation of the whole system,the process of developing the damage diagnosis Agent based on acoustic emission was introduced in detail.Through the detailed experiments,based on the acoustic emission technology,integrated with different time delay of arrival methods,the damage diagnosis Agent
was realized for the aluminum plate,glass fiber-epoxy composite plate and the carbon fiber reinforced plate.The work herein is the foundation of the implementation of the whole multi-Agent system for the large structure health monitoring.
