Abstract

With the development of technology worldwide, bridges are becoming larger, and the number of old bridges is also rapidly increasing. Monitoring the structural health of large, aging bridges is essential to preventing large-scale accidents. In this study, the application of a LoRa low-power wide-area network (LPWAN)-based wireless measurement system was investigated, and a LoRa wireless measurement system was established in the cable-stayed bridge section of Cheonsa Bridge, located in Shinan-gun, Jeollanam-do, Korea. The applicability of the LoRa LPWAN-based wireless monitoring system to large marine bridges was reviewed by comparing the performance and economic feasibility with wire-based monitoring systems that were built and operated by establishing a measurement system for the pylons, cables, and reinforcing girders of the bridge.

기술의 발전에 따라 전 세계적으로 교량은 대형화되고 있으며, 또한 노후 교량의 수도 급격히 증가하고 있다. 이들 대형, 노후 교량에 대한 구조건전성 모니터링은 대형 사고 예방을 위해 필수적이다. 본 연구에서는 LoRa LPWAN 기반 무선계측시스템의 적용에 대한 연구를 수행하였으며, 전남 신안군에 위치한 천사대교의 사장교 구간에 LoRa 무선계측시스템을 구축하였다. 교량의 주탑, 케이블, 보강거더에 대하여 계측시스템을 구축하여 기구축되어 운영 중인 유선기반 모니터링 시스템과 성능 및 경제성을 비교하여 LoRa LPWAN 기반 무선 모니터링 시스템의 대형 교량에서의 적용성을 검토하였다.
