A water supply network pollution source tracking and positioning method based on user complaint information

Abstract

The invention relates to a water supply pipe network pollution source tracking and positioning method based on user complaint information. The method comprises the following steps of S1, generating apollution matrix by using position information complained by a user; S2, judging the similarity among the candidate nodes and dividing the similarity; S3, increasing random complaint lag time and constructing a user complaint sample; And S4, carrying out training verification test on the convolutional neural network by using the complaint sample of the user, and applying the convolutional neural network to actual pollution source tracking and positioning. Compared with the prior art, according to the real-time user complaint information after the pollution accident happens, the user complaintmode recognition is adopted for pollution source positioning, the good pollution source recognition capability is achieved for water source pollution and non-water-source pollution, and certain robustness is achieved for uncertainty of the user complaint lag time. In the cities with incomplete pipe network water quality on-line monitoring equipment, the system has the advantages that the pollutionsource position can be quickly positioned, and the emergency response capability of cities to pipe network water quality accidents is enhanced.

Description

technical field [0001] The invention relates to a method for tracking and locating pollution sources, in particular to a method for tracking and locating pollution sources in water supply pipe networks based on user complaint information. Background technique [0002] The urban water supply network is the main way for residents to obtain drinking water. The safety of the water supply system directly affects the safety of residents' water use, and is also an important factor in ensuring social stability and economic development. The safe water supply of the water supply network refers to meeting the requirements of users in terms of water quality, water quantity and water pressure at the same time as possible on the premise that the factory water quality is qualified and there is sufficient water volume and pressure at the lowest possible cost. The water quality of the factory water can generally meet the national water quality standard after water treatment. There are often ...
