摘要
针对大型结构的多区域冲击监测特别是区域边界问题,提出了一种基于声发射技术的multi-agent黑板协作冲击定位方法。采用基于multi-agent技术的黑板协作模型监测大型结构各个传感器区域内部以及区域边界的冲击事件,利用agent的服务目录功能协调配置信号处理和声发射损伤定位模块,通过融合相关传感区域的定位结果,实现对整个结构可靠有效的评估。在大型航空铝板上的实验表明,该方法可以对大型结构的各个子区域特别是相邻边界区域进行有效的冲击定位。
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.
