<p>PURPOSE:To easily and quickly execute retrieval of piping or the like by expanding information of elements, which are related to an inputted position, in an expansion storage means from an already provided network storage means and displaying positions and connection relations of elements obtained by table retrieval. CONSTITUTION:This device consists of an information processor 10, a pipe network data base storage device 12, a water supply cut-off section table storage device 14, a mapping graphic display device 16, and a false data input device 18. Information corresponding to a water pipe diagram is stored as a data base in the pipe network data base storage device 12. When a water supply cut-off section is simulated, X and Y coordinate values are inputted from the false data input device 18 to designate a construction position. The information processor 10 retrieves the data base in the pipe network data base storage device 12 and expands obtained information on the water supply cut-off section table storage device 14 as a water supply cut-off section table. The pipe network is traced from the designated water supply cut-off position.</p> |
