Embodiment Construction

[0066] Below according to the accompanying drawings Figure 1 ~ Figure 3 , give a preferred embodiment of the present invention, and give a detailed description, so that the functions and characteristics of the present invention can be better understood.

[0067] see Figure 1 ~ Figure 3 , a method for interpolating missing data of pond culture dissolved oxygen according to an embodiment of the present invention, comprising the steps of:

[0068] S1: data acquisition;

[0069] In the data acquisition step:

[0070] A pond (length 100m, width 30m, average depth 1.5m) that has undergone standardized transformation and has been used for more than 5 years is selected as the test object. The slope protection of the pond is surrounded by cement prefabricated boards, and the cultured species is grass carp. The pond is also equipped with a 3kw impeller aerator and a 200w wind feeding machine.

[0071] In order to avoid the influence of aeration and feeding on the water quality mon...

Abstract

The invention provides a pond culture dissolved oxygen missing data interpolation method. The method comprises the following steps: S1, acquiring data; S2, preprocessing data; S3, establishing an SSIM model; S4, establishing a PCASSIM-based dissolved oxygen interpolation model by utilizing the SSIM model; and S5, evaluating the dissolved oxygen interpolation model based on the PCASSIM. According to the pond culture dissolved oxygen missing data interpolation method of the invention, two-person active variable data of feeding and oxygenation are introduced into traditional meteorological environment time sequence data, data screening is realized by using a PCA analysis method, a pond dissolved oxygen interpolation model is constructed by using an SSIM method, and dissolved oxygen missing data interpolation is realized.

Description

technical field [0001] The invention relates to the field of data interpolation methods, in particular to a data interpolation method for lack of dissolved oxygen in pond culture. Background technique [0002] At present, there is still a lack of a method that uses PCA analysis method to realize data screening, uses SSIM method to construct a pond dissolved oxygen interpolation model, and realizes a method for interpolating missing dissolved oxygen data. Contents of the invention [0003] In view of the deficiencies in the above-mentioned prior art, the present invention provides a method for interpolating missing data of pond culture dissolved oxygen, which introduces two human-made activity variable data of feeding and oxygenation into the traditional meteorological environment time-series data, and uses PCA analysis method Realize data screening, use SSIM method to construct pond dissolved oxygen interpolation model, realize dissolved oxygen missing data interpolation. ...
