Abstract

In order to evaluate dredging results scientifically the system which can manage and estimate working process by monitoring dredging process in real-time needs to be constructed. We constructed real-time dredging management system for guidance of a dredging vessel and for survey of dredging construction. This system was designed to have functions of dredger location by GPS, ship direction measurement by GPS/Gyroscope combination, Grab position measurement, dredging depth measurement and correction. In addition, we developed the programs for controlling and operating the constructed system. The system could induce the vessel to accurate position and conduct dredging according to plan and the effectiveness of the system was evaluated through the results of application to actual dredging construction site.

준설성과의 과학적 평가를 위해서는 준설공정을 실시간으로 모니터링하면서 작업을 관리하고 평가할 수 있는 시스템의 구축이 필요하다. 비콘DGPS를 이용하여 그래브 해상준설선의 유도와 준설측량 및 시공을 위한 실시간 준설시공관리시스템을 구축하였다. GPS에 의한 선박위치 측정, GPS/자이로스코프 통합장비에 의한 선박방향 측정, 그래브 위치측정, 준설심도측정 및 보정 등의 기능을 구현하였으며, 또한 구축된 준설공정관리시스템을 제어 운용하기 위한 프로그램을 개발하였다. 본 연구에서 구축된 시스템은 준설선을 정확한 위치로 유도하여 계획대로 준설을 수행할 수 있었으며 항만준설공사에의 적용성과를 통하여 그 효용성을 평가할 수 있었다.
