TRUNK PIPELINE ANALYZING SYSTEM FOR CITY WATER AND SEWERAGE BY UTILIZING MAP

摘要

PROBLEM TO BE SOLVED: To allow a city water dealer as a user to easily judge the replacement timing of a pipe of the trunk pipeline of city water to a pipe wider in diameter and the proper diameter of the trunk pipeline of sewerage on a map screen. SOLUTION: This trunk pipeline analyzing system is provided with a map recording means for recording the map data including building frames indicating a plurality of buildings, roads, and the trunk pipeline of city water, a building dynamic water head recording means for recording the dynamic water head of city water flowing to each building from the trunk pipeline of city water in relation with each building, a dynamic water head classifying means for classifying the dynamic water heads of the buildings recorded by the building dynamic water head recording means into a plurality of classes according to magnitudes, a building dynamic water head class recording means for recording the dynamic water head classes for individual buildings from the dynamic water head classifying means in relation with the building frame data recorded by the map recording means, and a dynamic water head class color display means for color-displaying the inside of the building frames on the map screen of a wide area according to the dynamic water head classes of the buildings based on the map data from the map recording means and the dynamic water head classes for individual buildings from the building dynamic water head class recording means.
