Japanese Unexamined Patent Publication No. Hei 8-96039 (“Water Pipe Information Management Apparatus”) states that “flow rate data or pressure data of water flowing at each measurement point of each water distribution pipe is measured, The data or each pressure data is displayed on the screen in association with the water distribution pipeline network diagram, and furthermore, an abnormal point such as water leakage is specified '', and `` each water pressure data obtained by measurement or simulation, Superimposing on a three-dimensional perspective view and displaying it on a screen, and further determining whether the water pressure of each building is excessive or insufficient based on the height data of each building. " However, the invention of the above-mentioned publication aims at "identification of abnormal points such as water leakage in individual water distribution pipelines", and "the number of buildings in a certain wide area and the hydraulic head class of the hydrant are set to each building. By displaying the rank by color for each frame or fire hydrant frame, the user tends to glance at the map screen of the wide area, and the general tendency of the distribution of the hydraulic head class of many building frames or hydrant frames in the wide area is large. Intuitively understand, and intuitively understand which area (narrow area) of the wide area has buildings or hydrants with low water heads accumulated, and that area (narrow area) To be able to easily determine whether it is necessary to replace the diameter of the main water supply pipeline with a larger one, and
"By displaying the water usage classes of a large number of buildings in a certain wide area by the rank of each building frame by color, the user can glance at the map screen of the wide area and see a large number of buildings in the wide area. It is possible to intuitively understand the general tendency of the distribution of the service water class of the frame, and to intuitively understand which area (small area) in the wide area has buildings with large use water consumption accumulated. To be able to easily determine whether it is necessary to increase the diameter of the main pipeline of the sewer installed in that area (narrow area). Its purpose and effects are significantly different from those of the present invention. In addition, the invention of the above publication discloses "displaying water pressure data on a screen by superimposing it on a sectional view or a three-dimensional perspective view". However, the invention of the above publication discloses,
For the purpose of `` determining whether the water pressure of each building is over or short, '' the `` hydraulic heads of a large number of buildings and fire hydrants in a certain wide area shall be ranked for each building frame or fire hydrant frame. Thereby, the user can intuitively understand the general tendency of the distribution of the hydraulic head class of a large number of building frames or fire hydrant frames in the wide area by just glance at the map screen of the wide area, Intuitively understand in which area (narrow area) buildings with low water heads or fire hydrants are accumulated, and increase the diameter of the main water supply pipeline in that area (narrow area). The purpose and effect of the present invention are greatly different from those of the present invention, which aims to easily determine whether or not it is necessary to replace the object.
