This study introduces recent research advances on the structural health monitoring (SHM) at Nanjing University of Aeronautics and Astronautics (NUAA). Distributed SHM technology for large-scale engineering structures is discussed. First, a hybrid wing box health monitoring evaluation system is presented. This evaluation system is developed to verify the piezoelectric sensor array-based active Lamb wave diagnostic method and the fiber Bragg grating sensor-based structural strain monitoring method. Second, distributed health monitoring technology based on the multi-agent system (MAS) technology is discussed. This research includes the individual agent design, the MAS-based SHM system architecture design, and three important aspects in designing the MAS-based SHM system. An evaluation case is presented in detail to show the advantages of the MAS-based SHM system. Finally, the study illustrates the motivation of the agents realized by a wireless sensor network. The developed wireless sensor nodes are also described.
