Abstract

This invention relates to the field of sprinkler design optimization technology, specifically to a method for optimizing the layout of a sprinkler water supply and drainage system based on hydraulic feedback. The method includes: generating an initial sprinkler coordinate set based on building spatial geometry information, and constructing a pipe network topology based on the initial sprinkler coordinate set; determining the nodal pressure of each sprinkler based on the pipe network topology; for each sprinkler, determining a first adjustment amount along the direction perpendicular to the branch pipe based on the sprinkler's required coverage radius and rated coverage radius, and determining a second adjustment amount along the branch pipe direction based on the sprinkler's nodal pressure and the equivalent path length between the sprinkler and the main pipe; adjusting the sprinkler coordinates based on the first and second adjustment amounts to obtain the adjusted sprinkler coordinates; and outputting the optimized sprinkler coordinate set and pipe network hydraulic parameters when all adjusted sprinkler coordinates meet preset convergence conditions. This invention achieves coordinated optimization of sprinkler layout and pipe network hydraulic characteristics.
