<p>PROBLEM TO BE SOLVED: To provide a method, capable of easily carrying out a simulation for suspension of the water supply displaying relation between the suspension of the water supply and the opening/shutting of a sluice value on an electric map. SOLUTION: Water pipes P1 , P2 , etc., and sluice valves V1 , V2 , etc., are written to the electronic map 2, and an original pipeline drawing, in which the direction of flow of the water in each water pipe is recognized as vector data, is created. The original pipeline drawing is displayed on a display device, and a closing signal for a prescribed sluice valve is input. A water pipe, in which the vector data becomes a mere line without direction by shutting the sluice valve, is retrieved and displayed using a computer. Accordingly, it is possible to carry out the simulation for suspension of the water supply easily and repeatedly, using a portable computer at a construction site, and confirmation of the range of suspension of the water supply and a suitable position of the sluice valve to be shut off are facilitated.</p> |
