Arrangement method and system for pipe network water quality monitoring points based on sudden pollution events

Abstract

The invention relates to an arrangement method of pipe network water quality monitoring points based on sudden pollution events. The method comprises the steps of obtaining the number of water qualitymonitoring points and the positions of all the water quality monitoring points; acquiring a plurality of pollution events; determining the pollutant monitoring time of each water quality monitoring point according to each pollution event; obtaining the number threshold of the water quality monitoring points; constructing a pipe network water quality monitoring point optimal arrangement model by taking the shortest pollutant monitoring time of the water quality monitoring points as a target, taking the number of the water quality monitoring points and the position of each water quality monitoring point as decision variables and taking the number threshold value of the water quality monitoring points as a constraint condition; and solving the model by adopting a Dijkstra algorithm, determining the number of optimal water quality monitoring points in the pipe network and the position of each optimal water quality monitoring point, and arranging the water quality monitoring points. According to the method and the system provided by the invention, the problem that a water quality monitoring point cannot quickly and accurately monitor the occurrence of a pollution event in the prior artis solved.

Description

technical field [0001] The invention relates to the field of water quality monitoring of water supply, in particular to a method and system for arranging water quality monitoring points of a pipe network based on sudden pollution events. Background technique [0002] A complete water supply quality monitoring system should include water source water quality monitoring system, water plant water quality monitoring system and pipe network water quality monitoring system. In general, according to the different causes of water quality changes and monitoring purposes in the water supply network, the arrangement of water quality monitoring points can be divided into the arrangement of conventional water quality monitoring points and the arrangement of water quality monitoring points for sudden pollution events. [0003] The layout of conventional water quality monitoring points is mainly based on the water age method, that is, using the characteristics of the topological structure ...
