Abstract

The invention discloses a structural health monitoring method and system resistant to sensor noise interference. The method comprises the following steps: acquiring structural damage data containing multiple damage scenes; calculating the cosine similarity between the structural damage data of each damage scene and the health signal, and determining the damage type of the corresponding structure according to the calculation result; wherein the damage types comprise structural damage and sensor damage; for a signal containing the structural damage, positioning a damage position in a corresponding structure based on a Transform network; and outputting a damage type of damage detection and a position parameter of damage positioning. According to the invention, automatic structural damage detection is realized through the vibration signal, the calculation cost can still be effectively managed even if a fault sensor exists, and meanwhile, high-accuracy damage detection and positioning are realized.
