초록

관망의 세그먼트를 파악하기 위한 알고리즘을 구동시키기 위해서는 관망의 주요 구성요소들인 절점, 파이프, 및 밸브 간의 상대적인 위치 관계를 세그먼트 탐색 알고리즘의 입력정보로 준비해야 한다. 실제 지자체 관망에 존재하는 세그먼트를 보다 정확하게 파악하기 위해서는 관망 수리해석 프로그램 구동을 위해 모델링된 관망 정보를 이용하기 보다는, 모든 제수밸브가 포함된 지자체 상수도 관망 GIS/CAD 데이터베이스를 이용하여 세그먼트 탐색에 적합하게 재구성된 관망 정보를 이용할 필요가 있다. 본 연구에서는 지자체 상수도 관망 GIS/CAD 데이터를 이용하여 관망 세그먼트 탐색에 적합한 노드-파이프-밸브 간의 상대적 위치관계를 수립할 수 있는 컴퓨터 계산 알고리즘을 개발하였으며, 이를 구현할 수 있는 MATLAB 프로그램을 개발하였다. 개발된 MATLAB 프로그램을 국내 지자체 상수도 관망에 적용하여 그 실효성을 확인하였다.

To run the algorithm for identifying the segments of a pipe network, the relative positional relation between nodes, pipes, and valves should be prepared as input information of a segment search algorithm. In order to more accurately identify the segments of real pipe network, pipe network GIS/CAD database that contains all isolation valves is more suitable than modeled pipe network information used for a hydraulic analysis program. In this study, we developed an algorithm that can establish the relative positional relations among node-pipe-valve suitable for pipe network segment search algorithms using GIS/CAD data of a real water supply network, and developed a MATLAB program that can implement it. The effectiveness of the developed MATLAB program was confirmed by applying it to a portion of a real municipal pipe network.
