構造物のヘルスモニタリングのためのリアルタイムデータ処理法の提案

抄録

A smart sensor is required if we are to popularize health monitoring using the vibration of a structure. This device is used to evaluate the vibration characteristic of the structure. To detect the variance in the vibration characteristic from the vibration data of a structure, a time-frequency analysis technique that can detect the change of the frequency components of the vibration data over time is needed. This report proposes the real-time data processing method with narrowband band-pass filters based on the one degree of freedom vibration system for the evaluation of structural vibration characteristics. This method is applicable to processors with low computation loads and memory capacities.
