Embodiment Construction

[0132] Embodiments of the present invention are described in further detail below in conjunction with the accompanying drawings:

[0133] see figure 1 Shown, the comprehensive evaluation method of aquaculture water quality based on improving fuzzy of the present invention, comprises steps:

[0134] Step 1. First determine the types of water quality evaluation factors, construct an improved evaluation standard set, and determine an appropriate membership function;

[0135] The above-mentioned process of constructing the improved evaluation standard set is as follows:

[0136] Select environmental factors such as temperature, dissolved oxygen, pH, ammonia nitrogen, color and taste, and floating matter that are crucial to the water quality environment of aquaculture to construct an evaluation factor set, that is, U={temperature, dissolved oxygen, pH, ammonia nitrogen content, color and taste ,floating object}.

[0137] After determining the evaluation factor set, before calcul...

Abstract

The invention discloses an aquaculture water quality comprehensive evaluation method based on improved fuzziness, and the method comprises the steps: firstly determining the types of water quality evaluation factors, constructing an improved evaluation standard set, and determining an appropriate membership function; then constructing a water quality evaluation factor weight vector, and reconstructing the water quality evaluation factor weight in the time dimension; thirdly, carrying out comprehensive evaluation, and then making a final decision; and finally, testing and verifying the method by using a water quality evaluation factor model. Compared with a single-factor evaluation method and a traditional fuzzy comprehensive water quality evaluation method, the result shows that compared with the single-factor evaluation method and the traditional fuzzy comprehensive water quality evaluation method, the method has the advantages that the change of the water quality factor content is more moderate under the interference condition, and the water quality can be better and accurately evaluated. Therefore, when the method is applied to an actual scene, the loss of equipment can be wellreduced, and the service life of the equipment is prolonged.

Description

technical field [0001] The invention belongs to the technical field of water quality evaluation, in particular to an improved fuzzy-based comprehensive evaluation method for aquaculture water quality. Background technique [0002] The quality of water in the aquaculture industry directly affects the quality of aquatic products. The research on aquaculture environment mainly focuses on the research on water quality environmental factors. Scholars have done a lot of research on the detection of water quality environmental factors. [0003] Fuzzy mathematics is the mathematics that uses mathematical methods to study and deal with "fuzzy" phenomena. The so-called ambiguity mainly refers to the "unclearness" of the transition boundary between the differences of objective things. This ambiguity has been applied in many fields, such as oil and gas exploration, wind turbine fault diagnosis, etc. Because there is ambiguity between the degree of water environmental pollution and w...
