Abstract

Underground utility tunnels are spaces densely packed with various infrastructure facilities, such as power, telecommunications, and water supply and drainage systems, making internal environment management crucial. An investigation into accident cases and on-site demands in these tunnels revealed that while fires and floods are the most common types of incidents, the demand for real-time condensation prevention and response is frequent according to on-site managers. Condensation occurs due to the difference in humidity and temperature between the inside and outside of the tunnel. Frequent or prolonged condensation can lead to metal pipe corrosion, electrical failures, and reduced equipment lifespan. Therefore, this study developed a control algorithm and monitoring system to prevent condensation in underground utility tunnels. The proposed control algorithm estimates the likelihood of condensation in real-time based on the measured temperature and humidity and suggests appropriate responses for each stage to the managers. Finally, a practical condensation prevention monitoring system was built based on the developed algorithm, verifying the feasibility and applicability of this technology in the field.

지하 공동구는 전력, 통신, 상하수도 등 다양한 인프라 시설이 밀집해 있는 공간으로, 내부 환경 관리가 매우 중요하다. 공동구에서 발생한 사고 사례 및 현장 요구를 조사한 결과, 가장 많이 발생하는 사고 형태는 화재 및 침수였지만, 실제 공동구에서 근무하는 현장 관리자들의 의견에 따르면 실시간 결로 예방 및 대응에 대한 요구가 빈번한 것으로 확인되었다. 결로 현상은 공동구 내부 습도와 내부 및 외부의 온도 차이로 인해 발생하며, 빈번하게 발생하거나 장시간 지속될 경우 금속 관로 부식, 전기적 고장, 장비 수명 단축 등의 문제를 야기할 수 있다. 따라서, 본 연구에서는 지하 공동구 내 결로 생성을 방지하기 위한 경고 알고리즘 및 모니터링 시스템을 개발하였다. 제안된 경고 알고리즘은 실시간으로 측정되는 온도와 습도를 바탕으로 결로 발생 가능성을 추정하고, 각 단계에 따른 관리자의 대응 방식을 제안한다. 마지막으로, 개발된 알고리즘을 바탕으로 실제 구동 가능한 결로 예방 모니터링 시스템을 구축하여, 해당 기술의 현장 적용 가능성과 활용성을 검증하였다.
