Abstract:

For the multi region impact monitoring and the region border problem in the large scale structure, the multiagent blackboard coordination impact localization method based on acoustic emission is proposed. Every sensor region and border in the large structure are monitored by using a multi agent blackboard coordination model, and the signal processing and the damage location function module is distributed by the server directory, and thus the reliable and effective assessment for the whole structure is given by fusing the identification results of the monitored areas. A large aerospace aluminum plate structure experiment shows that the method can monitor each sub region efficiently, particularly the border upon region in the large scale structure.
