Method and device for generating water quality information map

Abstract

The invention discloses a method and device for generating a water quality information map, and relates to the field of water quality monitoring. The method comprises the following steps: setting a plurality of monitoring points on a map, then obtaining water quality information data of the monitoring points, constructing a water quality prediction model, obtaining water quality prediction data ofthe monitoring points according to the water quality information data and the water quality prediction model, displaying the water quality prediction data on the map, and generating a water quality information map to predict the water quality of a monitoring area. Through water quality evaluation information monitoring data, by combining correlation analysis and influence relations among multiplewater quality parameters, the method establishes a nonlinear relation water quality prediction model containing multiple parameters, can predict water quality changes in advance on the basis of the water quality prediction model, and visually displays prediction results on a water quality information map, so that water quality risk hidden dangers are eliminated in advance, and water quality safety is effectively guaranteed. The method can be widely applied to water quality monitoring fields such as environmental water affairs and water conservancy monitoring.

Description

technical field [0001] The invention relates to the field of water quality prediction, in particular to a method and device for generating a water quality information map. Background technique [0002] Nowadays, people have higher and higher requirements on the quality of water supply, and ensuring the safety of water quality has always been a problem worth studying. Generally speaking, the water quality of water supply mainly involves real-time monitoring of water quality evaluation parameters such as pH, turbidity, residual chlorine, ammonia nitrogen, electrical conductivity, water temperature, and biological toxicity index. How to reveal the influence relationship between water quality factors based on the existing monitoring data, combined with the correlation analysis between multiple parameters of the water body, and at the same time determine the nonlinear relationship of multiple parameters is one of the difficulties and focuses of water quality data prediction model...

How to reveal the influence relationship between water quality factors based on the existing monitoring data, combined with the correlation analysis between multiple parameters of the water body, and at the same time determine the nonlinear relationship of multiple parameters is one of the difficulties and focuses of water quality data prediction modeling , the more parameters, the more difficult and complex the modeling will be, and it will also bring greater uncertainty to the final modeling results

Moreover, the existing water quality monitoring can only display the current water quality monitoring information of the monitoring point, and cannot predict the large-scale water quality change trend in the monitoring area to make preventive measures.
