<p>PURPOSE:To estimate the dynamic water pressure balance of the whole pipeline net easily by setting the plane arrangement relation of the pipeline network according to an X-Y coordinate plane, and by displaying ground height and dynamic water pressure according to the respective conduit line sections of the pipeline network, with a Z coordinate. CONSTITUTION:By a front-end processor 1, a pipeline network chart is read out of a pipeline network chart file 7A, and when the input of analysis condition from an input device 4 is provided, then an input model is created to be housed in an input model file 7B. Besides, by a hydraulic analysis processor 2, analysis object data are read out of the file 7B, and the flow speed and dynamic water pressure of respective conduit lines are found to be housed in an analysis result file 7C. Then, by a back-end processor 3, from the file 7C, data are read, and every conduit unit, plane arrangement data at both the end sections are set to be X-Y coordinate data, and land height data and dynamic water pressure data in the coordinate are extracted in a Z coordinate and are developed in working memory. Besides, when the memory data are housed in video memory, then a three-dimensional dynamic water pressure gradient chart is displayed on a display device 5.</p> |
