Description

Technical Field

[0001] The present invention belongs to the technical field of road construction planning, and in particular relates to a method, device and storage medium for selecting a road iron tailings material source taking carbon emissions into consideration. Background Art

[0002] Road construction plays a key role in national and social development. It not only promotes economic growth and improves the quality of life of residents, but also enhances national defense security and promotes social progress. However, with the rapid development of road construction, non-renewable resources such as natural gravel are consumed in large quantities, resulting in resource shortages and increased environmental pressure.

[0003] Iron tailings are the largest byproduct of my country's mining solid waste. The added value of the product is not high, the utilization rate is less than 20%, and it increases at a rate of more than 300 million tons per year. The large accumulation of iron tailings not only wastes land resources and causes environmental pollution, but also poses a huge safety hazard.

[0004] Reasonable use of iron tailings in road construction can effectively reduce the demand for natural gravel, save natural resources, help reduce road construction costs, and solve the environmental and safety problems caused by iron tailings accumulation. However, the distribution of iron tailings is affected by the location of iron ore resources. Compared with traditional road construction material sources, its distribution is characterized by a large number and relatively concentrated distribution, usually located in remote areas with poor road conditions.

[0005] The existing technology only selects the traditional road construction material source in a simple and single way based on distance and material cost, lacking comprehensive consideration of factors such as the quantity and distribution of iron tailings source, transportation capacity, road driving conditions, and carbon emission costs. In the construction of large-scale road networks, as the project progresses, the material supply path continues to change, resulting in increased transportation and carbon emission costs, affecting construction cost control and corporate carbon emission management, resulting in exceeding carbon quotas, increasing corporate costs in the carbon trading market, and limiting the widespread application of iron tailings in road construction. Therefore, there is an urgent need for a method for selecting iron tailings sources based on a highway network, which comprehensively considers transportation and carbon emission costs, solves the problem of increased transportation and carbon emission costs caused by unreasonable selection of iron tailings sources, and promotes the efficient use of iron tailings in road construction. Summary of the invention

[0048] The present invention provides a method, device and storage medium for selecting a road iron tailings material source taking carbon emissions into consideration, which are used to systematically consider the quantity and distribution of the iron tailings material source, the capacity of transportation vehicles, road driving conditions and carbon emission costs during road construction, so as to provide a more preferred iron tailings material source for the proposed road, so as to solve the technical problem in the prior art that road construction is limited to a single and simple iron tailings material source selection method, resulting in an increase in the transportation and carbon emission costs of the entire construction project as the road construction progresses.

[0049] The specific implementation of the present invention is further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0050] First, see Figure 1 , showing a schematic diagram of a method for selecting a source of road iron tailings considering carbon emissions described in the present application, comprising:

[0051] S1: Select the construction area according to the proposed road, obtain the proposed road information, highway network information, iron tailings source information in the construction area, and set the vehicle parameters;

[0052] S2: According to the vehicle parameters and the proposed road information, the proposed road is segmented to obtain multiple proposed road sections; and according to the highway network information and the iron tailings source information, the driving distance from each iron tailings source to each proposed road section through the highway network is calculated;

[0053] S3: Based on the parameters of the transport vehicle and the distance from each iron tailings source to each proposed road section through the highway network, calculate and obtain the transportation cost and carbon cost of each iron tailings source to each proposed road section through the highway network;

[0055] S5: Select the iron tailings source corresponding to each proposed road section according to the total cost from each iron tailings source to each proposed road section.

[0056] In this embodiment, a method for selecting a source of iron tailings for roads taking carbon emissions into consideration is provided. During the road construction process, the proposed road is divided into sections by obtaining information on the proposed roads, highway network information, iron tailings sources and vehicle parameters within the construction area, and the driving distance from each iron tailings source within the construction area to each proposed section is obtained. The total cost from each iron tailings source to each proposed section is calculated based on the driving distance, combined with the transportation cost and the carbon cost. Therefore, the corresponding iron tailings source and its transportation path are selected for each proposed section based on the total cost, which effectively improves the control of transportation efficiency and total transportation cost, and solves the problem that the selection of iron tailings sources in the prior art is limited to a simple and single selection method, lacks systematic consideration of factors such as the number and distribution of iron tailings sources, the capacity of transportation vehicles, road driving conditions and carbon emission costs, resulting in an increase in the overall cost, causing troubles in the control of the transportation and carbon emission costs of the entire project, and limiting the technical problem of the wide application of iron tailings in road construction.

[0057] Optionally, the highway network information in the present invention includes: a vector diagram of the highway network in the construction area and location parameters of toll stations; the iron tailings source information includes: the number N of iron tailings sources in the construction area and the location parameters of each iron tailings source; the proposed road information includes: the total length L of the proposed road and the mass D of iron tailings required for the construction of each kilometer of road; the vehicle parameters include: the basic cost h, the single transport volume k, and the fuel consumption per kilometer of the vehicle when traveling on ordinary roads O R , the carbon emissions per unit distance when the vehicle is traveling on ordinary roads e1, the carbon emissions per unit distance when the vehicle is traveling on the expressway network e2, the fuel consumption per kilometer when the vehicle is traveling on the expressway network O G , carbon trading price c, the cost per kilometer of the highway network P1, and the oil price P2.

[0058] Optionally, step S2 in the present invention specifically includes:

[0059] S2.1: Divide the proposed road into M proposed sections based on the single transport volume k, the total length of the proposed road L, and the mass of iron tailings D required for each kilometer of road construction, and That is, the mass of iron tailings required for each proposed road section shall not be less than the single transport capacity k of the vehicle;

[0060] S2.2: Obtain the length l and geometric midpoint of each proposed road segment;

[0061] S2.3: Obtain the driving distance from each iron ore tailings source to the geometric midpoint of each proposed road segment.

[0062] In this embodiment, when dividing the proposed road sections, the mass of iron tailings required for each proposed road section is not less than the single transport capacity of the vehicle, thereby avoiding waste of transport capacity in the process of transporting iron tailings for each proposed road section and ensuring the construction efficiency of the road construction.

[0063] Meanwhile, in this embodiment, the geometric midpoint of each proposed road section is used as the transportation midpoint of the iron tailings during the process of obtaining the driving distance, so as to facilitate obtaining a relatively accurate driving distance.

[0064] Optionally, step S2.3 in the present invention may specifically include:

[0065] S2.3.1: Take the iron tailings source as the initial point and obtain the driving distance l from the initial point to the toll station entrance i ,

[0066] i=1,2,……,N;

[0067] S2.3.2: Obtain the driving distance l from the geometric midpoint of each proposed road section to the toll station exit j , j = 1, 2, ..., M;

[0068] S2.3.3: Calculate the driving distance l from the entrance to the exit of the toll station on the expressway network ij , i=1,2,...,N; j=1,2,...,M;

[0069] S2.3.4: Calculate the driving distance d from each iron ore tailings source through the highway network to the geometric midpoint of each proposed road section ij , d ij = l i +l j +l ij ; i=1,2,...,N; j=1,2,...,M.

[0070] Optionally, in step S2.3 of the present invention, the driving distance l from the initial point to the toll station entrance obtained by the A-star algorithm is i , the driving distance l from the geometric midpoint of each proposed road section to the toll station exit j and the driving distance from the toll station entrance to the exit on the expressway network. ij , i=1,2,...,N; j=1,2,...,M.

[0071] Furthermore, any driving distance acquisition method known to those skilled in the art may be used to obtain the driving distance from the geometric midpoint of each proposed road section to the toll station exit and the driving distance from the toll station entrance to the exit on the expressway network.

[0072] Specifically, the cost formula used by the A-star algorithm in the present invention is:

[0073] F=G+H

[0074]

[0075] Among them, F represents the comprehensive cost; G is the actual cost from the current node to the target node; H is the estimated cost from the current node to the target node, which is calculated based on the Haversine formula to calculate a more accurate distance between two points on the sphere; R is the radius of the earth, usually 6371 kilometers; φ1 and φ2 are the latitudes of the two nodes on the highway network; Δφ is the latitude difference between the two nodes; Δλ is the accuracy difference between the two nodes.

[0076] It should be noted that the A-star algorithm used in this implementation to calculate the driving distance from the entrance to the exit of a toll station on the expressway network only provides a more preferred method of calculation and acquisition. Those skilled in the art can choose a specific method of calculating and acquiring the driving distance based on actual usage requirements.

[0077] Optionally, in step S3, the transportation cost calculation model of each iron tailings source through the expressway network to each planned road section is:

[0078] C Yij =h+(l i +l j ) R K j P2+l ij P1+l ij O G K j P2,

[0079]

[0080] The calculation model of the carbon cost of each iron tailings source through the highway network to each proposed road section is:

[0081] C Tij =0.001(l i +l j )K j e1c+0.001l ij K j e2c;

[0082] Where i = 1, 2, ..., N; j = 1, 2, ..., M, K j The number of transport vehicles required for each proposed road section, rounded up; C Yij is the transportation cost of iron tailings source i to the proposed road section j through the highway network; C Tij is the carbon cost of iron tailings source i to the proposed road section j through the highway network.

[0083] In this embodiment, the transportation cost and carbon cost of each iron tailings source to each proposed road section through the highway network are calculated and obtained, so that the transportation cost and carbon cost can be comprehensively considered to obtain the total cost of each iron tailings source to each proposed road section through the highway network. The iron tailings source corresponding to each proposed road section is selected according to the total cost to obtain the optimal solution.

[0084] Further, in step S4, the total cost from each iron tailings source to each proposed road section is calculated as C Zij =C Yij +C Tij , where C Zij That is, the total cost from each iron tailings source to each proposed road section.

[0085] Optionally, in step S5 of the present invention, according to the total cost from each iron tailings source to each proposed road section, the iron tailings source corresponding to the minimum total cost of each proposed road section is selected in turn, thereby completing the selection of the iron tailings source corresponding to each proposed road section. During the road construction process, iron tailings are supplied to the proposed road section from the corresponding iron tailings source, the total cost is effectively controlled, and the efficiency of road construction is ensured.

[0086] Optionally, step S6 may be further included: based on the iron tailings material source information, the iron tailings material source corresponding to the minimum total cost of each planned road section is visualized and output on a map of the construction area.

[0087] In this embodiment, the iron tailings material source corresponding to the minimum total cost of each planned road section is visualized and output on the map of the construction area. Specifically, it can be visualized on the electronic map, and then the visualized iron tailings material source is output to facilitate technical personnel in the field to carry out road construction.
