Abstract

본 연구는 건설공사 현장에 적용되고 있는 무선센서네트워크 관련 기술현황을 검토하고, USN 기반의 콘크리트 양생온도 관리방법에 대한 현장적용성 실험을 통하여 그 개선 방안을 도출하는데 목적이 있다. 건설분야에서의 USN 관련연구는 주로 공사의 품질관리 및 시설물 유지관리, 안전관리를 중심으로 이루어지고 있으나, 현장여건 및 통신네트워크 등 실용화를 위한 세부적인 연구가 필요한 것으로 나타났다. 또한 현장사무실에서의 실시간 원격모니터링에 의한 콘크리트의 온도관리가 콘크리트내 소형의 무선센서를 활용 하여 USN 환경에서도 가능한 것을 알 수 있었다. 다만, 센서의 매립깊이에 따른 전파인식정도나 내장건전지의 전력소모 및 전송방식 등 현장에서의 가변적 상황에 대응할 수 있는 보다 안정화된 다양한 시스템 구축을 위한 연구가 필요한 것으로 나타났다. As the construction industry has recently been transformed by the emergence of ubiquitous and intelligent technology, there have been major changes in the management methods employed. Specifically, next-generation construction management systems have been developed that collect and analyze many pieces of information in real time by using various wireless sensors and networks. The purpose of this study is to understand the current status of Ubiquitous Sensor Networks (USN) in the construction sector, and to gain fundamental data for a system of measuring concrete curing temperature in a construction site that employs a USN. By investigating the application status of USN, it was confirmed that USN has mainly been applied to the maintenance of facilities, safety management, and quality control. In addition, a field experiment in which the curing temperature of concrete was measured using a USN was carried out to evaluate two systems with wireless sensor networks, and the applicability of these systems on site was confirmed. However, it is estimated that the embedded wireless sensor type is affected by metal equipment on site, internal battery of sensor and concrete depth, and studies to provide more stable system by USN are thus required.
