Description

Technical Field

[0002] With the rapid development of railway construction, the reasonable site selection of the four power fields (including communication, signal, power, and power supply and transformation) of railways has become an important link in ensuring the safe and efficient operation of railways. Railway lines are usually long, and the distribution density of the four power fields along the lines is high. Therefore, how to arrange the four power fields in the appropriate location to meet technical requirements and reduce construction costs has become an urgent issue to be solved.

[0003] At present, the site selection of the fourth railway power station mainly relies on manual site selection methods. Site selection personnel preliminarily select suitable locations in topographic maps or geographic information systems based on specification manuals and their own experience, and confirm the final site selection plan through on-site investigation. In actual operation, this site selection method relies heavily on the experience and judgment of site selection personnel.

[0004] This traditional site selection method is inefficient, and it is impossible to intuitively compare various influencing factors during the site selection process, resulting in unscientific decision-making. In addition, the lack of a systematic evaluation model makes it impossible to conduct quantitative analysis between different alternative site selection plans, and the site selection results are easily interfered by subjective factors, affecting the accuracy of the site selection. Therefore, how to conduct a scientific site selection evaluation has become an urgent problem to be solved. Summary of the invention

[0047] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0048] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0049] With the rapid development of railway construction, the reasonable site selection of the four railway power fields (including communication, signal, power, and power supply and transformation fields) has become an important link in ensuring the safe and efficient operation of railways. Railway lines are usually long, and the distribution density of the four power fields along the line is high. Scientific and objective site selection of the location of the four railway power fields can ensure that the layout of the field meets the technical requirements, reduce construction costs, and improve the efficiency and safety of the overall project.

[0050] The main solution of the embodiment of the present application is: first, the data of the four electric field sites are obtained to provide basic information for the subsequent site selection, ensure the accuracy and pertinence of the site selection work, and improve the efficiency of data processing and analysis; then, multiple alternative site selection points are generated in combination with the data of the distribution points and the preset distance, which increases the diversity and selection space of the site selection, helps to ensure that the optimal site selection position is found under different conditions, and improves the flexibility and operability of the site selection; finally, a preset site selection evaluation model is used to quantitatively score multiple alternative site selection points to ensure the objectivity and scientificity of the site selection process, reduce the interference of human subjective factors, and finally help determine the optimal site selection plan and improve the reliability of the site selection results. Based on the acquisition of data, the generation of spare points and the application of evaluation models, the method used in this application enables the site selection process to shift from subjective judgment to objective quantitative analysis, which improves the scientificity and accuracy of the site selection of the four railway electric field sites.

[0051] It should be noted that the execution subject of the embodiment of the present application can be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device capable of realizing the above functions, etc. The following takes a computer as an example to illustrate this embodiment and the following embodiments.

[0052] Based on this, the present application embodiment provides a method for selecting a site for a railway four-electric field. Figure 1 , Figure 1 This is a flow chart of the first embodiment of the method for selecting a site for four railway electric fields in the present application.

[0053] In this embodiment, the site selection method for the four-electric field of the railway includes steps S10 to S30:

[0054] Step S10, obtaining four electric field flat point distribution data;

[0055] It should be noted that the four power fields along the railway mainly refer to the communication fields (including communication base stations, repeater stations and independent tower fields), signal fields (including relay stations, line stations), power fields (including interval power stations, distribution stations, substations and independent box-type substation fields) and power supply and substation fields (including traction substation fields, switchgear fields, and substations). The four power field layout data refers to the geographical location and related attribute information of various fields related to the four power systems of the railway on the railway line. These data include but are not limited to: the location coordinates of the four power fields, the specific locations of communication, signal, power, and power supply and substation fields along the railway, such as longitude and latitude or other coordinate data; field type information, identifying the specific type of each field, such as communication field, signal field, etc.; field attribute information, technical requirements, environmental restrictions, physical characteristics and other information related to the field, such as the size, function, and requirements for the external environment (such as the distance from the railway line, geological conditions, etc.) of the field.

[0056] It is understandable that the location information and attribute data of the field related to the railway four-electric system are collected from the geographic information system, that is, the GIS system, or from sources such as topographic maps and field surveys. These data include the geographic coordinates, type, and specific requirements for site conditions of the field, which serve as the basis for subsequent site selection analysis and generation of alternative sites.

[0057] As an example, before obtaining the data of the four electric field flats, it also includes: based on the site selection obstacle area data integrated by the geographic information system, displaying the site selection area to complete the layout of the four electric field flats.

[0058] Among them, the site selection obstacle area data refers to the regional data that may affect or restrict the site selection during the site selection process of the railway four-electric field, which is integrated by the GIS system. These obstacle areas usually include areas where field construction cannot be carried out or areas that need to be avoided during site selection. Specifically, the site selection obstacle area data may include the following: natural geographical obstacles, such as mountains, rivers, lakes, wetlands, forests and other natural terrain features, which are usually not suitable for field construction; humanities and legal restriction areas, such as legally stipulated protection areas (such as nature reserves, cultural relics protection areas), military restricted areas, built-up residential areas, etc., these areas are protected by humanities or laws and cannot be constructed; engineering restrictions, such as existing large-scale infrastructure (such as railways, bridges, roads, etc.) or geological conditions that are not easy to transform (such as landslide areas, geological faults, etc.), these obstacles restrict the layout of the field. The site selection obstacle area data can be integrated through GIS to clearly display and identify these areas that are not suitable for construction, so as to effectively avoid these obstacles in the site selection process and optimize the site selection plan for field layout.

[0059] It can be understood that in the site selection process of the four power field sites of the railway, for example, for a 100km long railway line, based on the mileage of the required points and the type of field sites to be arranged, the GIS system is first used to integrate and process the site selection obstacle area data; then, through GIS technology, these obstacle areas are clearly marked and visualized on the map to help planners identify feasible site selection areas; finally, on this basis, the preliminary layout of the four power field sites is completed, that is, the specific field sites are determined within the feasible area, and the site selection personnel can intuitively carry out site selection design in the three-dimensional geographic image, and can avoid site selection obstacles to ensure the rationality and feasibility of the site selection.

[0060] Step S20, based on the four electric field layout data, obtaining multiple backup site selection points for a single field;

[0061] It should be noted that a single site refers to a specific type of site in the railway four-electric system, such as a communication site, a signal site, a power site or a power supply and substation site. In the site selection process, each site needs to find a suitable location for construction, so it is necessary to generate multiple alternative site selection points for each site. Alternative site selection points refer to multiple potential site selection locations recommended for each railway four-electric site. Through analysis and calculation, these points meet the site selection requirements and provide multiple alternative options for decision makers to further evaluate and select.

[0062] It is understandable that this technical step determines multiple possible site selection locations for a specific field (such as communication, signal, power or power supply and substation field) by analyzing the layout data of the four power systems of the railway. These alternative site selection points are alternative options generated by comprehensively considering geographical information and restrictions on the premise of meeting specific site selection standards and requirements, for further evaluation and selection of the optimal location.

[0063] As an example, based on the four electric field flat point layout data, multiple alternative site selection points for a single field flat are obtained, including: based on the four electric field flat point layout data and a preset distance, a site selection range is obtained; based on the site selection range, a site selection permission area is obtained; based on the site selection permission area, the site selection permission area is cut according to a preset distance to obtain a point area to be selected; based on the point area to be selected and a clustering algorithm, alternative site selection points are obtained.

[0064] Among them, the preset distance refers to the minimum distance between the field flats or between the field flats and other railway facilities set according to specific standards or planning requirements. This distance is used to limit the site selection range of the field flats to ensure that the location of the field flats meets the operational safety requirements and effectively covers the required area. The site selection range refers to the possible site selection area determined based on the four-electric field flats layout data and the preset distance. This range represents all geographical areas that meet the preset distance requirements under the influence of the layout data, that is, the overall area where the field flats can be sited. The site selection allowed area refers to the area that can eventually be used to build the field flats after further eliminating various site selection obstacles (such as natural geographical obstacles, legal protection areas, etc.) within the site selection range. These areas do not have any factors that hinder the construction of the field flats, so they are actually optional locations. The area to be selected refers to the small area or grid point obtained by dividing the area according to the preset distance (such as a certain grid size or step length) in the site selection allowed area. These areas represent potential site selection locations for subsequent screening and evaluation.

[0065] It can be understood that, first, based on the four electric field flat point distribution data and the preset distance requirements, a possible site selection range is determined, which represents all locations that meet the distance standard. Then, within this site selection range, exclude areas that are not recommended for site selection, including areas where the distance from the railway centerline is less than the minimum specified distance, areas where the distance from the railway centerline is greater than the maximum specified distance, and also exclude site selection obstacle areas, such as areas that cannot be used for construction due to terrain, laws or other restrictions, to obtain the actual permitted areas that can be sited. Next, these permitted areas are divided according to the preset distance to form multiple candidate point areas, which represent potential candidate locations. Finally, by using a clustering algorithm to analyze these candidate point areas, a set of alternative site selection points are screened out to further evaluate and determine the final field flat site selection in subsequent steps.

[0066] As an example, based on the area of ​​points to be selected and the clustering algorithm, alternative site selection points are obtained, including: obtaining the number of required alternative site selection points; based on the clustering algorithm, the number of required alternative site selection points and the area of ​​points to be selected, obtaining the regional geometric center of each point; based on the regional geometric center of each point, obtaining the alternative site selection points.

[0067] The number of alternative site selection points refers to the total number of alternative site selection points that need to be selected and set in order to ensure the accuracy and flexibility of site selection. This number is determined based on actual needs, project scale and site selection complexity, and is usually set during the project planning stage so that subsequent evaluation and decision-making can be based on these points.

[0068] It is understandable that the number of required alternative site selection points is first determined, that is, the total number of alternative site selection points that need to be generated is set according to the project requirements and design standards. Next, a clustering algorithm is used to classify all possible points in the area to be selected to meet the set number of points. The algorithm calculates the regional geometric center of each category, which is the coordinate of each alternative point. Finally, the final alternative site selection points are determined through these geometric center points. This process ensures that a reasonably distributed set of alternative site selection points is generated according to the requirements in the target area to facilitate further evaluation and decision-making.

[0069] Step S30, based on the alternative site selection points and a preset site selection evaluation model, obtaining scores for the alternative site selection points to complete site selection.

[0070] It should be noted that the preset site selection evaluation model refers to a designed evaluation framework or algorithm that is used to systematically evaluate the pros and cons of alternative site selection points. This model will comprehensively consider multiple factors, such as construction costs, geological conditions, land use rules, adjacent resources, system rules, etc., and score each site selection point through methods such as hierarchical analysis and fuzzy analysis. The score of the alternative site selection point refers to the value calculated based on the preset site selection evaluation model. This score represents the comprehensive performance of each alternative site selection point under various influencing factors. The higher the score, the better the performance of the site selection point in each evaluation indicator, and thus it is more suitable as the final site selection plan.

[0071] It is understandable that, first of all, the preset site selection evaluation model is a tool based on multi-factor analysis, which can comprehensively evaluate the advantages and disadvantages of different site selection points. This model may consider multiple parameters such as geographical location, environmental impact, economic cost, resource availability, etc. By comparing and analyzing the various attributes of the alternative site selection points with the standards in the evaluation model, the system will calculate a score for each alternative site selection point, which reflects the comprehensive performance of the point under all site selection conditions. Finally, based on the score, the best site selection plan is selected to complete the final site selection.

[0072] This embodiment provides a method for selecting the site of the four electric field flats on the railway. The application first obtains the data of the layout of the four electric field flats to provide basic information for subsequent site selection, ensure the accuracy and pertinence of the site selection work, and improve the efficiency of data processing and analysis; then, multiple alternative site selection points are generated in combination with the layout data and the preset distance, which increases the diversity and selection space of the site selection, helps to ensure that the optimal site selection location is found under different conditions, and improves the flexibility and operability of the site selection; finally, a preset site selection evaluation model is used to quantitatively score multiple alternative site selection points to ensure the objectivity and scientificity of the site selection process, reduce the interference of human subjective factors, and finally help determine the optimal site selection plan and improve the reliability of the site selection results. Based on the acquisition of data, the generation of spare points and the application of evaluation models, the method used in this application enables the site selection process to shift from subjective judgment to objective quantitative analysis, which improves the scientificity and accuracy of the site selection of the four electric field flats on the railway.

[0073] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the above-mentioned embodiment 1 can refer to the above introduction, and will not be repeated later. Figure 2 , Figure 2 This is a flow chart of the second embodiment of the method for selecting the site of the four electric field flats of the railway of the present application. Step S30 of the method for selecting the site of the four electric field flats of the railway includes steps S31 to S33:

[0074] Step S31, based on various influencing factors and the backup site selection points, obtaining specific indicators of various influencing factors;

[0075] It should be noted that the specific indicators of various influencing factors refer to specific data and parameters related to site selection, which are used to evaluate the feasibility and superiority of the site selection. Influencing factors may include environment, transportation, land use, economic cost, safety, infrastructure, resource availability and other aspects. Specific indicators may involve geological conditions, transportation convenience, surrounding environmental protection requirements, construction and operation costs, water supply and power supply and other resource guarantees, and safety risk assessment. These specific indicators can provide quantitative data support for subsequent site selection decisions.

[0076] It is understandable that starting from the selected alternative site locations, various specific influencing factors related to these locations are identified and collected. These factors include multiple aspects such as environment, transportation, resources, economic costs, etc., and are expressed through quantitative indicators to provide objective data basis for subsequent site selection decisions. These indicators can help decision makers more accurately evaluate the pros and cons of each site selection point and ensure that the final selected location is the best after comprehensively considering all influencing factors.

[0077] Step S32, based on the specific indicators of the various influencing factors, obtain a sub-item evaluation matrix of the factors affecting site selection;

[0078] It should be noted that the evaluation matrix of factors affecting site selection refers to a structured data table or matrix. This matrix lists various influencing factors (such as environment, transportation, resources, economic costs, etc.) according to their specific indicators, and conducts quantitative or qualitative evaluation of these indicators. The performance of each alternative site selection point under different influencing factors will be presented in this matrix, providing basic data for subsequent comprehensive evaluation and final site selection decision. This matrix can intuitively show the advantages and disadvantages of each point in various aspects, thereby assisting scientific decision-making.

[0079] It is understandable that an evaluation matrix is ​​generated based on the specific influencing factors of each alternative site selection point (such as environment, transportation, resources, etc.). In this matrix, the performance of each site selection point is evaluated in different items according to different influencing factors, so as to systematically display the advantages and disadvantages of each point in each indicator, providing support for subsequent comprehensive analysis and final decision-making.

[0080] As an example, based on the field weight evaluation analysis matrix and the field site selection influencing factors sub-item evaluation matrix, it includes: obtaining the four power field site selection influencing factors to obtain the first-level indicator layer and the second-level indicator layer; based on the hierarchical analysis method, the Delphi method, the first-level indicator layer and the second-level indicator layer, obtaining the field determination matrix; based on the field determination matrix, the first-level indicator layer and the second-level indicator layer, obtaining the field weight evaluation analysis matrix.

[0081] Among them, influencing factors refer to various key factors used to evaluate and select the location of the four power field. These influencing factors cover all important aspects that affect the site selection decision of the field, including but not limited to construction costs, geographical and geological conditions, land use rules, adjacent resources and system rules. The first-level indicator layer refers to the main categories or major factors that affect the site selection of the four power field, and the second-level indicator layer refers to the specific sub-factors under the first-level indicators, which are used to further refine and quantify the site selection conditions. The field determination matrix is ​​a multi-level evaluation tool used to comprehensively evaluate the impact of each first-level and second-level indicator on the site selection of the field. Through methods such as hierarchical analysis and Delphi method, the determination matrix is ​​used to calculate the relative importance and weight of each indicator in order to systematically evaluate and compare different field site selection schemes. The field weight evaluation analysis matrix is ​​calculated based on the field determination matrix and is used to represent the comprehensive weight of each influencing factor. These weights reflect the importance of each indicator in the final site selection decision and are presented in the form of a matrix to support decision makers in weighing and choosing between multiple alternative fields.

[0082] It is understandable that in the site selection process, the first-level and second-level indicator layers that affect the site selection are established by first collecting and sorting out the various influencing factors of the four power field flats. The first-level indicator layer includes the main influencing categories, such as construction costs, geographical and geological conditions, land use rules, etc., while the second-level indicator layer is refined to specific factors, such as the filling and excavation volume in the construction cost, geological settlement information, etc. Then, these first-level and second-level indicators are analyzed using quantitative and qualitative methods such as hierarchical analysis and Delphi method to construct a field flat judgment matrix, which helps evaluate the relative importance of each indicator. Finally, based on the field flat judgment matrix, combined with the information of the first-level and second-level indicator layers, a field flat weight evaluation analysis matrix is ​​generated to comprehensively evaluate the advantages and disadvantages of each field flat site selection, and ultimately provide a scientific basis for site selection decisions.

[0083] As an example, the first-level indicator layer includes: construction cost information, geographical and geological information, land use rules, adjacent resource information, and system rules. The second-level indicator layer includes: construction cost information, field filling and excavation engineering volume, field protection engineering volume, and access road engineering volume; geographical and geological information, flood level information, and geological settlement information; land use rules, distance to railway tracks, planned land use information, environmental protection land use information, temporary land use information, oil and gas pipeline layout information, and electromagnetic interference level; adjacent resource information, electricity use distance, water use distance; and system rules, distance to the four power system layout locations. Specifically, the first-level indicator layer and the second-level indicator layer and their determination matrix are shown in the following table:

[0094] According to the influencing factors of different types of fields, the first-level index layer and the second-level index layer are normalized to establish the weight evaluation analysis matrix S of different types of fields. Taking the power field as an example, it is shown in the following table:

[0095]

[0096] Step S33, based on the field weight evaluation analysis matrix and the field site selection influencing factor sub-item evaluation matrix, obtain the scores of the alternative site selection points to complete the site selection.

[0097] It should be noted that the site weight evaluation analysis matrix is ​​a matrix used to represent the relative importance of different influencing factors. Based on the weights of various influencing factors, the matrix systematically ranks and quantifies each influencing factor to reflect its degree of influence on the site selection decision. By applying these weights to the specific indicators in the "site site selection influencing factor sub-item evaluation matrix", the comprehensive score of each alternative site selection point can be calculated, thereby helping to determine the optimal site selection plan.

[0098] It can be understood that, first of all, the site weight evaluation analysis matrix is ​​used to express the importance of different site selection influencing factors, that is, the weight. These weights are based on expert evaluation, historical data or other analytical methods, and reflect the priority of each factor in the site selection decision. Then, the site selection influencing factor sub-item evaluation matrix is ​​a quantitative evaluation of the performance of each alternative site selection point on different influencing factors to form an evaluation matrix. Then, these two matrices are combined, and a comprehensive score for each alternative site selection point is obtained through weighted calculation. Among them, the site selection influencing factor sub-item evaluation matrix C is:

[0099]

[0100] Multiply the evaluation matrix C by the field weight matrix S to get the evaluation scores of different candidate points. The specific algorithm formula is:

[0101]

[0102] Among them, p is the evaluation score and r is the weight value. This evaluation score reflects the relative advantages and disadvantages of each site selection point after considering all important influencing factors. The higher the evaluation score, the better the performance of the site in each key factor, and the more it meets the needs of site construction. Therefore, this score becomes the basis for the final site selection decision, thus completing the site selection process.

[0103] In this embodiment, first, by analyzing the alternative site selection points, specific influencing factors related to the site selection, such as terrain, climate conditions, and traffic convenience, are extracted. The technical effect of this step is to ensure a comprehensive understanding of the site selection points and lay the foundation for subsequent evaluation. Then, for each alternative site selection point, a quantitative evaluation is performed according to the specific indicators of various influencing factors to form a sub-item evaluation matrix. The technical effect of this step is to systematically organize and evaluate the influencing factors to ensure that the performance of each site selection point can be intuitively and quantitatively compared and analyzed. Finally, the sub-item evaluation matrix of the influencing factors is combined with the field weight evaluation analysis matrix, and the comprehensive score of each alternative site selection point is obtained by weighted calculation. The technical effect of this step is to achieve scientific and objective site selection decisions through quantitative methods to ensure that the selected points meet the actual needs and priority factors of field construction. Through the above steps, the alternative site selection points are systematically analyzed and evaluated comprehensively and accurately. The specific indicators of various influencing factors ensure a deep understanding of the points; the sub-item evaluation matrix of the influencing factors provides a basis for comparison; and the introduction of the weight evaluation analysis matrix enables the site selection decision to take into account the priority of actual needs. The technical effect of this overall derivation process is that it achieves the optimal decision on site selection through scientific quantitative methods, ensuring that the selected site can meet the expected needs in all aspects.

[0104] For example, in order to help understand the implementation process of the method for selecting the site of the four-electric field of the railway obtained by combining this embodiment with the above-mentioned embodiment 1, please refer to Figure 3 , Figure 3 A brief flow chart of the site selection method for the four-electric field of railway is provided, specifically:

[0105] First, before the formal site selection, based on the site selection obstacle area data integrated in the GIS system, the area where the site selection can be carried out is displayed and determined, so as to complete the four-electric field site layout. Secondly, the data of the site selection personnel through the four-electric system field site layout is collected through the GIS system to establish the basic information of the entire site selection process. Then, based on the four-electric field site layout data and the preset distance, the potential site selection range is determined, and the area allowed for site selection is further generated based on the range. In the site selection allowed area, it is cut according to the preset distance to form multiple areas to be selected. The clustering algorithm is used to process the area to be selected to generate multiple alternate site selection points. The alternate site selection points are alternative field locations, which will be further evaluated and screened. Furthermore, based on the generated alternate site selection points, various specific indicators that affect site selection are extracted, such as construction cost, geographical conditions, land use rules, etc. The specific indicators of various influencing factors are sorted out to form a sub-item evaluation matrix. This matrix is ​​used to quantify and compare the advantages and disadvantages of each alternate site selection point. Finally, the weight evaluation analysis matrix of the field is constructed by combining the information of the primary indicator layer and the secondary indicator layer through the hierarchical analysis method and the Delphi method. This matrix is ​​used to reflect the importance of each indicator in the final site selection. The sub-item evaluation matrix is ​​combined with the weight evaluation analysis matrix, and the score of each alternative site selection point is obtained through weighted calculation. Based on these scores, the optimal site selection point is finally determined. Through this flowchart, a scientific and systematic site selection process for the four railway power field can be realized, from data acquisition to evaluation decision-making, to ensure that the selected field location meets actual needs and is the most preferred.
