レーザセンシングによる橋梁モニタリングシステムの試作
レーザセンシングによる橋梁モニタリングシステムの試作
近年のインフラの老朽化問題において、人手不足等の背景から自動モニタリングシステムが求められている。本研究では、光切断法や位相差測距方式といったレーザセンシングを用いた橋梁モニタリングシステムを試作した。実際に橋梁で実験を行い、既存の加速度計や変位計と比較して、提案手法の有効性について考察した。
Automatic monitoring systems are required due to deterioration of large-scale infrastructures in recent years. In this research, we developed a prototype of bridge monitoring system using laser sensing based on light section method and phase difference ranging method. Experiments were actually carried out on bridges in operation. We discussed the effectiveness of the proposed method in comparison with methods using accelerometers and displacement gauges.
