Description

Technical Field

[0001] The present invention belongs to the technical field of power grid waste material valuation, and in particular relates to a power grid waste material valuation method, system and equipment. Background Art

[0002] Electric power companies are important livelihood enterprises in my country, and they can provide people with the electricity resources they need for daily life. With the continuous development of society, people's demand for electricity is increasing. In order to meet people's increasing demand for electricity, electric power companies have carried out large-scale power grid construction and technological transformation, and in the process, a large number of scrapped power grid waste materials have been generated. However, these waste materials are not completely useless, but can be recycled and reused. Recycling power grid waste materials can reduce resource waste and environmental pollution on the one hand, and improve the economic benefits of power companies on the other hand. It can be seen that it is very necessary to recycle power grid waste materials. In the process of recycling power grid waste materials, the valuation of power grid waste materials is the most important part of recycling.

[0003] However, the current valuation method for power grid waste materials is only for the valuation of the internal components of the waste materials, without considering the current value of the power grid waste materials themselves. For example, some waste materials are not seriously damaged due to their short use time, and can be reused through some repair operations. The secondary use is the value of the waste materials themselves. Simply valuing the internal components of the waste materials is obviously not comprehensive enough, which will lead to low accuracy of the valuation results and make it difficult to reflect the comprehensive value of power grid waste materials. In view of this, the present invention designs a method, system and device for valuing power grid waste materials. Summary of the invention

[0004] The purpose of the present invention is to propose a method, system and equipment for valuing power grid waste materials. By statistically analyzing the current total value of the internal components and the current total value of the power grid waste materials, and combining the above to derive the current comprehensive value corresponding to the power grid waste materials, the comprehensive value of the power grid waste materials is evaluated.

[0005] The purpose of the present invention can be achieved by the following technical solutions:

[0006] The first aspect of the present invention provides a method for estimating the value of power grid waste materials. In the specific implementation process of the method, a system for estimating the value of power grid waste materials is required. The system includes a statistical classification module for power grid waste materials, a basic parameter acquisition module for power grid waste materials, a material composition database, a material statistics module for the composition of power grid waste materials, a current damage coefficient analysis module for power grid waste materials, a current recycling price acquisition module, an evaluation cloud platform and a display terminal;

[0007] The power grid waste material statistical classification module is used to count the number of power grid waste materials existing in the power enterprise, and obtain the material type corresponding to each waste material, and then classify all power grid waste materials existing in the power enterprise into various material types according to the material types corresponding to each waste material. At this time, the number of classified material types is counted, and each material type is numbered in a preset order, marked as 1, 2, ..., i, ... n respectively, and at the same time, the number of waste materials under each material type is counted, and each waste material under each material type is numbered, and marked as 1, 2, ..., j, ... m in sequence;

[0008] The basic parameter acquisition module for power grid waste materials is used to obtain the corresponding material product model, original purchase price and usage time of each waste material under each material type, and form the basic parameter set P of waste materials under each material type. i r (p i r 1,p i r 2,...,p i r j,...,p i r m), p i r j represents the value corresponding to the basic parameter of the jth waste material under the i-th material type, r represents the basic parameter, r = d1, d2, d3, respectively representing the material product model, the original purchase price, and the length of use. The basic parameter acquisition module of power grid waste materials sends the basic parameter set of waste materials under each material type to the power grid waste material composition material statistics module, the power grid waste material current damage coefficient analysis module and the evaluation cloud platform respectively;

[0009] The power grid waste material composition material statistics module receives the waste material basic parameter set of each material type sent by the power grid waste material basic parameter acquisition module, and extracts the material product model corresponding to each waste material under each material type from the waste material basic parameter set under each material type, and then matches it with the internal component material quantity and the content of each component material corresponding to each material product model of each material type in the material component database, so as to obtain the internal component material quantity and the content of each component material corresponding to each waste material under each material type. At this time, the component materials corresponding to each waste material under each material type are numbered and marked as 1, 2, ..., k, ... z respectively, so that the content of each component material corresponding to each waste material under each material type constitutes the waste material composition material content set Q ij (q ij1,q ij 2,...,q ij k,...,q ij z), q ij k represents the content of the kth component material corresponding to the jth waste material under the ith material type. The power grid waste material component material statistics module sends the waste material component material content set to the evaluation cloud platform;

[0010] The current damage coefficient analysis module for power grid waste materials receives the basic parameter set of waste materials under each material type sent by the basic parameter acquisition module for power grid waste materials, and is used to analyze the current damage coefficient of each waste material under each material type. The specific analysis process performs the following steps:

[0011] F1: collecting the current appearance images of the waste materials under each material category to obtain the current appearance images of the waste materials under each material category;

[0012] F2: extracting the appearance contour of the waste materials from the current appearance images of the waste materials under each material type, so as to obtain the current surface area corresponding to each waste material under each material type;

[0013] F3: Analyze the number of cracks and paint-shedding areas on the surface of each waste material under each material type from the current appearance images of each waste material under each material type, and number each crack on the surface of each waste material as 1, 2, ..., a, ... x, and number each paint-shedding area on the surface of each waste material as 1, 2, ..., b, ... y;

[0014] F4: Focus the current appearance images of each waste material under each material type on each crack and each paint peeling area, and then extract the edge contours of the cracks and the edge contours of the paint peeling, so as to obtain the area of ​​each crack and the area of ​​each paint peeling corresponding to each waste material under each material type, and form the surface crack area set s of the waste material 裂纹 ij (s 裂纹 ij 1,s 裂纹 ij 2,...,s 裂纹 ij a,...,s 裂纹 ij x) and the paint peeling area of ​​waste materials 掉漆 ij (s 掉漆 ij 1,s 掉漆 ij2,...,s 掉漆 ij b,...,s 掉漆 ij y);

[0015] F5: Calculate the current surface damage coefficient of each waste material under each material type according to the current surface area of ​​each waste material under each material type, the set of surface crack areas of waste materials, and the set of surface paint peeling areas of waste materials;

[0016] F6: extracting the material product model corresponding to each waste material under each material type from the basic parameter set of waste materials under each material type, and then matching it with the standard surface area corresponding to each material product model of each material type in the material composition database to obtain the standard surface area corresponding to each waste material under each material type, thereby comparing the current surface area corresponding to each waste material under each material type with the standard surface area corresponding to the waste material, and obtaining the current size damage coefficient corresponding to each waste material under each material type;

[0017] F7: Calculate the current total damage coefficient corresponding to each waste material under each material type according to the current surface damage coefficient and current size damage coefficient corresponding to each waste material under each material type, and send it to the evaluation cloud platform;

[0018] The current recycling price acquisition module is used to acquire the current recycling price per unit content of each component material of each waste material under each material type, and form a current recycling price set R of the waste material component material content per unit content ij (r ij 1,r ij 2,...,r ij k,...,r ij z), r ij k represents the current recycling price per unit of the kth component material of the jth waste material under the ith material type, which is then sent to the evaluation cloud platform;

[0019] The evaluation cloud platform receives a set of basic parameters of waste materials under each material type sent by the basic parameter acquisition module of waste materials in the power grid, receives a set of material content of waste materials components sent by the material statistics module of waste materials components in the power grid, receives a current total damage coefficient corresponding to each waste material under each material type sent by the current damage coefficient analysis module of waste materials in the power grid, and receives a set of current recycling prices per unit content of waste materials components sent by the current recycling price acquisition module, so as to count the material content of each waste material component under each material type according to the set of material content of waste materials components and the set of current recycling prices per unit content of waste materials components. The corresponding current value is calculated, and the current total value of the internal components of each waste material under each material type is calculated based on this. At the same time, the original purchase price and the use time of each waste material under each material type are extracted from the basic parameter set of the waste materials under each material type. Therefore, the current total value of each waste material under each material type is calculated based on the current total damage coefficient, original purchase price and use time of each waste material under each material type. Then, the current comprehensive value of each waste material under each material type is evaluated based on the current total value of the internal components and the current total value of each waste material under each material type, and the result is sent to the display terminal;

[0020] The display terminal receives the current comprehensive value corresponding to each waste material under each material category sent by the evaluation cloud platform, and then sorts each waste material under each material category in descending order according to its corresponding current comprehensive value, obtains the value sorting result corresponding to each waste material under each material category, and displays the sorting result;

[0027] Step 6. Statistics of the total value of the current internal components of waste materials: According to the material content set of the waste material components and the current recycling price set of the material unit content of the waste material components, the total value of the current internal components corresponding to each waste material under each material type is counted;

[0028] Step 7. Current damage coefficient analysis of power grid waste materials: The current total damage coefficient corresponding to each waste material under each material type is counted through the current damage coefficient analysis module of power grid waste materials;

[0029] Step 8. Statistics of the current total value of waste materials: Count the current total value of each waste material under each material type according to the current total damage coefficient, original purchase price and usage time of each waste material under each material type;

[0030] Step 9. Current comprehensive value assessment of waste materials: assess the current comprehensive value of each waste material under each material type based on the current total value of its internal components and its current total value;

[0031] Step 10. Ranking and display of the value of power grid waste materials: sort the waste materials under each material category in descending order according to their corresponding current comprehensive value, and display the value ranking results of the waste materials under each material category.

[0032] According to a preferred implementation manner of the first aspect of the present invention, the material composition database is used to store the quantity of internal components and the content of each component material corresponding to various material types and various material product models, store the standard surface areas corresponding to various material types and various material product models, and store the current comprehensive value weight factor corresponding to the current total value of the internal components of the waste materials and the current total value of the waste materials themselves.

[0061] The power grid waste material statistical classification module is used to count the number of power grid waste materials existing in the power enterprise, and obtain the material type corresponding to each waste material, and then classify all power grid waste materials existing in the power enterprise into various material types according to the material types corresponding to each waste material. At this time, the number of classified material types is counted, and each material type is numbered in a preset order, marked as 1, 2, ..., i, ... n respectively. At the same time, the number of waste materials under each material type is counted, and each waste material under each material type is numbered, and marked as 1, 2, ..., j, ... m in sequence.

[0062] The basic parameter acquisition module of power grid waste materials is used to obtain the corresponding material product model, original purchase price and usage time of each waste material under each material type, and form the basic parameter set P of waste materials under each material type. i r (p i r 1,p i r 2,...,p i r j,...,p i r m), p i r j represents the value corresponding to the basic parameters of the jth waste material under the ith material type, r represents the basic parameters, r=d1, d2, d3, respectively representing the material product model, original purchase price, and usage time. The basic parameter acquisition module of power grid waste materials sends the basic parameter sets of waste materials under each material type to the power grid waste material composition material statistics module, the power grid waste material current damage coefficient analysis module and the evaluation cloud platform.

At this time, the component materials corresponding to each waste material under each material type are numbered and marked as 1, 2, ..., k, ... z respectively, so that the content of each component material corresponding to each waste material under each material type constitutes the waste material composition material content set Q ij (q ij 1,q ij 2,...,q ij k,...,q ij z), q ij k represents the content of the kth component material corresponding to the jth waste material under the ith material type. The power grid waste material component material statistics module sends the waste material component material content set to the evaluation cloud platform.

[0066] The current damage coefficient analysis module of power grid waste materials receives the basic parameter set of waste materials under each material type sent by the basic parameter acquisition module of power grid waste materials, and is used to analyze the current damage coefficient of each waste material under each material type. The specific analysis process performs the following steps:

[0070] F4: Focus the current appearance images of each waste material under each material type on each crack and each paint peeling area, and then extract the edge contours of the cracks and the edge contours of the paint peeling, so as to obtain the area of ​​each crack and the area of ​​each paint peeling corresponding to each waste material under each material type, and form the surface crack area set s of the waste material 裂纹 ij (s 裂纹 ij 1,s 裂纹 ij 2,...,s 裂纹 ij a,...,s 裂纹 ij x) and the paint peeling area of ​​waste materials 掉漆 ij (s 掉漆 ij 1,s 掉漆 ij 2,...,s 掉漆 ij b,...,s 掉漆 ij y);

[0071] F5: Calculate the current surface damage coefficient of each waste material under each material type according to the current surface area of ​​each waste material under each material type, the surface crack area set of waste materials and the surface paint peeling area set of waste materials Where η ij It is expressed as the current surface damage coefficient corresponding to the jth waste material under the i-th material type, s 裂纹 ij a represents the area of ​​the a-th crack corresponding to the j-th waste material under the i-th material type, s 掉漆 ij b represents the area of ​​paint peeling at the bth location corresponding to the jth waste material under the i-th material type, S ij It is represented by the current surface area corresponding to the jth waste material under the i-th material type;

[0072] F6: Extract the material product model corresponding to each waste material under each material type from the basic parameter set of waste materials under each material type, and then match it with the standard surface area corresponding to each material product model of each material type in the material composition database to obtain the standard surface area corresponding to each waste material under each material type, thereby comparing the current surface area corresponding to each waste material under each material type with the standard surface area corresponding to the waste material to obtain the current size damage coefficient corresponding to each waste material under each material type Where λ ij It is represented by the current size damage coefficient of the jth waste material under the i-th material type, S i ' j It is expressed as the standard surface area corresponding to the jth waste material under the i-th material category;

Where σ ij It is expressed as the current total damage coefficient corresponding to the jth waste material under the i-th material type, and is sent to the evaluation cloud platform.

[0074] In the process of analyzing the current damage coefficient of each waste material under each material type, this embodiment not only analyzes the current surface damage coefficient corresponding to each waste material, but also analyzes the current size damage coefficient corresponding to each waste material, and integrates the above damage coefficients to form the current total damage coefficient corresponding to each waste material under each material type. The current total damage coefficient can comprehensively and intuitively reflect the current total damage status of the waste materials, avoiding the problem of one-sided analysis and non-compliance with the actual damage status caused by simply analyzing the current surface damage status or the current size damage status of the waste materials, and provides a reliable statistical basis for the subsequent statistics of the current total value of each waste material.

[0075] The current recycling price acquisition module is used to obtain the current recycling price per unit content of each component material of each waste material under each material type, and form the current recycling price per unit content of the component material of the waste material set R ij (r ij 1,r ij 2,...,r ij k,...,r ij z), r ij k represents the current recycling price per unit content of the kth component material of the jth waste material under the i-th material type, which is then sent to the evaluation cloud platform.

[0076] The evaluation cloud platform receives the basic parameter set of waste materials under each material type sent by the basic parameter acquisition module of waste materials in the power grid, receives the material content set of waste materials components sent by the material statistics module of waste materials components in the power grid, receives the current total damage coefficient corresponding to each waste material under each material type sent by the current damage coefficient analysis module of waste materials in the power grid, and receives the current recycling price set of the unit content of the waste materials components sent by the current recycling price acquisition module, so as to count the current value of each component material corresponding to each waste material under each material type according to the material content set of the waste materials components and the current recycling price set of the unit content of the waste materials components. ij k=r ij k*q ij k, where o ij k represents the current value of the kth component material of the jth waste material under the i-th material type, and based on this, the total value of the current internal components corresponding to each waste material under each material type is calculated. Where O ij It is expressed as the total value of the current internal components corresponding to the jth waste material under the i-th material type. At the same time, the original purchase price and usage time corresponding to each waste material under each material type are extracted from the basic parameter set of waste materials under each material type.
