Abstract

The evolution of civil engineering technology, exemplified by recent milestones like the completion of the Gangnam Global Business Center (GBC), has fostered the construction of expansive civil and architectural structures both above and below the earth's surface. This surge in construction necessitates a commensurate advancement in research and technology pertaining to safety protocols applicable to these vast edifices. Such protocols encompass a spectrum of concerns, ranging from the preemptive mitigation of accidents to the effective management of exigencies such as fires. As the trajectory of construction endeavors continues unabated, encompassing both subterranean and elevated domains, a concomitant imperative emerges to refine the methodologies underpinning precise indoor positioning. To address this need, an innovative web-based simulator has been devised to emulate indoor positioning scenarios for rigorous testing. This research further entails the development of an indoor positioning data Application Programming Interface (API) fortified by Geographic Information System (GIS) spatial operation techniques. This API is anchored in the construction of intricate test data, centered on the spatial layout of building 13 at the Electronics and Telecommunications Research Institute (ETRI). Consequently, the study renders feasible the expeditious provisioning of diverse signal-based and image-based spatial information, pivotal for enhancing the navigational acumen of mobile devices. Path delineation, cellular signal mapping, landmark identification, and ancillary navigational aids are among the manifold datasets promptly furnished by the indoor positioning data API. In summation, this study engenders a crucial leap towards the fortification of safety protocols and navigational precision within the expansive confines of modern architectural wonders.

최근 강남 글로벌 비즈니스센터(GBC) 건설 등 토목기술이 발전해 감에 따라 지상·지하에 대규모 토목·건축물들이 건설되고 있으며, 이와 같은 대규모 시설물의 안전사고 방지, 화재와 같은 위급사항 대처 등과 관련한 기술과 연구가 진행되고 있다. 지상·지하의 개발과 활용이 활발해 짐에 따라 실내에서의 정확한 위치 정보 확보를 위한 연구가 다양하게 진행되고 있으며, 본 연구에서 실내측위 테스트를 위해서 웹 환경에서 손쉽게 가상으로 실내측위를 해 볼 수 있는 시뮬레이터를 개발하였다. 이를 위해서 한국전자통신연구원(ETRI) 13동을 대상으로 실내측위를 위한 테스트 데이터를 구축하고, GIS 공간연산 기법을 이용하는 실내측위 데이터 API(Application Programming Interface)를 개발하였다. 본 연구를 통해 모바일 단말에서 요구되는 다양한 경로정보, 셀 정보, 랜드마크 등 신호 및 영상기반측위에서 요구되는 다양한 공간정보를 실내측위 데이터 API를 통해 신속히 제공이 가능하다.
