Automatic cruise water quality monitoring system of geographic information system

Abstract

The invention requests to protect an automatic cruise water quality monitoring system based on a geographic information system; the system works as follows: preprocessing pollution source data, and building a similar experimental model of a river dustproof water supply pipe network; and establishing a pollution source large class feature library and similarity analysis method. Therefore, the identification capability of the pollution source large class is improved to deal with the potential water quality problem. In order to solve the problem that the combined response of the water quality original index to the pollution source is not significant and inseparable, a method for performing feature extraction by using an auto-encoder of deep nonlinear features is provided, a k-means++ clustering method is combined to construct a feature library for the extracted high-dimensional features so as to increase the inter-class difference of the pollution source, and a cosine distance is introduced to perform similarity measurement. Finally, industrial wastewater, domestic sewage, livestock and poultry breeding wastewater and muddy water are adopted to carry out comparative analysis on the performance of the pollution source judgment method provided by the invention. Technical support is provided for promoting river intelligent water affair construction, and the system has certain reference significance for anomaly detection in other fields.

Description

technical field [0001] The invention belongs to the field of safety production information management, and in particular relates to an automatic cruising water quality monitoring system of a geographic information system. Background technique [0002] With the increasing mechanization, automation, and intelligence of mining, the amount of river pollution has increased significantly, seriously endangering the occupational health of miners and threatening the safety of river production. As a necessary guarantee for implementing comprehensive dust control measures in rivers, the river dust prevention and water supply pipe network plays a decisive role in the comprehensive dust prevention effect. [0003] As an important facility to prevent and control pollution hazards under mine rivers, the river dust prevention and water supply pipe network plays a decisive role in ensuring the comprehensive dust prevention facilities to achieve the expected dust prevention effect.

Problems solved by technology

However, according to the field survey of rivers, most of the rivers in our country only rely on experience to design new construction, reconstruction and expansion of water supply pipe networks, lack of design schemes guided by optimization theory, and do not comprehensively consider the construction reliability, economy and hydraulic power of water supply pipe networks. Water quality requirements often lead to waste of investment in the construction of dust-proof water supply pipe networks, and even some mining faces still have unqualified water volume, water pressure, and water quality, and pipelines in some areas are severely corroded, which eventually leads to comprehensive dust-proof measures that cannot work normally or fail to meet expectations Dust-proof effect, a threat to the safe production of coal mines
