초록
본 연구에서는 항만구조물의 구조건전성 모니터링을 위한 Imote2 센서 플랫폼 기반의 고민감도 스마트 무선센서를 개발하였다. 이를 위해 첫째, 고성능 Imote2 센서 플랫폼을 기반으로 하고, 고민감도 MEMS 가속도계를 탑재한 스마트 무선센서를 설계하였다. 둘째, 스마트 무선센서가 독자적으로 모니터링을 수행할 수 있도록 하는 내장 소프트웨어를 설계하였다. 마지막으로, 개발된 스마트 무선센서의 성능을 모형 케이슨 구조물에서의 실험을 통해 검증하였다.
Abstract
In this study, a high-sensitive smart wireless sensor based on an Imote2 sensor platform is developed for structural health monitoring of harbor structures. To achieve the objective, the following approaches are implemented. Firstly, the smart wireless sensor based on the high-performance Imote2 sensor platform is designed to measure acceleration with high sensitivity from structures. Secondly, embedded software is designed for autonomous structural health monitoring. Finally, the performance of the smart wireless sensor is estimated from experimental tests on a lab-scaled caisson structure.
