Water quality pollutant change monitoring system based on time sequence association and clustering analysis

Abstract

The invention relates to a water quality pollutant change monitoring system based on time sequence association and clustering analysis, and the system comprises a real-time riverway water quality detection device which is used for collecting multi-dimensional real-time riverway water quality data; a data preprocessing device which is used for preprocessing the real-time river channel water qualitydata; a historical time sequence acquisition device which is used for storing the preprocessed real-time river channel water quality data, forming a historical time sequence of each measurement object and acquiring a dynamic reasonable threshold value of each measurement object; and a pollutant change measuring device which is used for clustering to obtain main pollution change conditions according to the historical time sequences of the plurality of detection stations. Compared with the prior art, the system has the advantages of being high in automation degree, good in real-time performance, high in efficiency and the like.

Description

technical field [0001] The invention relates to the technical field of river water quality monitoring, in particular to a system and method for monitoring changes in water quality pollutants based on time series correlation and cluster analysis. Background technique [0002] With the shortage of surface water resources and other issues in our country becoming more and more prominent today, the "River Chief System" has become a powerful system to promote the sustainable use of water resources and promote the coordination of social and economic development and water environment carrying capacity. River water quality detection is the process of monitoring and measuring the types of pollutants in water bodies, the concentration and change trend of various pollutants, and evaluating the water quality status. In the river water quality detection system, the detection data in different river basins and different river sections has become an important source of information and decis...

AI Technical Summary

Problems solved by technology

[0003] In particular, in the river water quality detection and pollution analysis of the river chief system, the measurement and change tracking of the main pollutants in the river is a very important reference index. However, the traditional water quality detection methods are very complicated for the analysis of the main pollutants. And it takes a lot of time, and it is difficult to obtain it fully automatically, in real time, and on the spot
