Method and device for generating differentiated river patrol strategy

Abstract

The invention relates to water engineering and environmental engineering technology, and is a method and device for generating differentiated river patrol strategies. The device includes: a data cleaning module, which is used for data preprocessing, data cleaning, and sample filtering to obtain a clean sample set; a data model training module , use the clean sample set to train and evaluate the random forest model to predict the water quality level of rivers and lakes, use the Gaussian mixture clustering model to perform cluster analysis on all rivers and lakes within the target window period, and expand the training sample set through label propagation technology; Model prediction and data visualization module, through the random forest model to predict the water quality of rivers and lakes to obtain the corresponding water quality grade information of rivers and lakes, and the important value of replacement features used to evaluate the ranking scores of rivers and lakes; decision-making auxiliary generation module, combined with rivers and lakes Water quality grade information and river and lake patrol ranking scores are used to formulate differentiated river patrol strategies. The invention can reasonably allocate river patrol resources based on different river and lake water environment conditions, and realize differentiated river patrol.

Description

Technical field [0001] The present invention relates to the field of water engineering and environmental engineering, and in particular, the method and apparatus of differentiated patrol strategies. Background technique [0002] Comprehensive implementation of the river long system is to implement the concept of green development, promote the internal requirements of ecological civilization construction, is to solve complex water problems, maintain effective measures for healthy life in rivers and lakes, is a systematic innovation of water treatment system to ensure water safety. Carried out the rivers and lake inspection and discovered in time to promote the resolution of river lake water pollution, water environment problem is the main job of "river length". [0003] At present, the river's patrol river uses "no difference" patrol strategy, that is, the river is required to use the same frequency to carry out the same frequency, such as the same level of the river to implement ...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the technical problems existing in the prior art, the present invention provides a method for generating differentiated river patrol strategies, which can rationally allocate river patrol resources based on different river and lake water environment conditions, realize differentiated river patrol, and achieve water environment quality as a priority. Guided by promoting river chiefs to pay more attention to the state of rivers and lakes with poor water quality and their existing problems, and gradually increase the proportion of rivers and lakes with good water quality
