The invention belongs to the technical field of sensing monitoring, and provides an aircraft state monitoring method based on a wireless passive sensor, and the method achieves the real-time stress monitoring of a key structure of an aircraft through the manufacturing of a single wireless passive sensor and the construction of an equilateral triangle sensor array. The maximum stress of the to-be-measured point is accurately calculated by using the deformation quantity monitoring result of the sensor and combining the generalized Hooke's law. According to the method, the mechanical influence of the cable weight of the measurement means on the structural body is effectively avoided, the monitoring accuracy and reliability are improved, and effective support is provided for health condition evaluation and safety early warning of the aircraft structure.

    本发明属于传感监测领域技术领域,提供基于无线无源传感器的飞行器状态监测方法,该方法通过制作单支无线无源传感器并构建等边三角形传感器阵列,实现对飞行器关键结构的实时应力监测。利用传感器的形变量监测结果,结合广义胡克定律,准确计算待测点的最大应力。该方法有效规避了测量手段本身线缆重量对结构体的力学影响,提高了监测的准确性和可靠性,为飞行器结构的健康状况评估和安全预警提供了有效支持。
