Description

Technical Field

[0001] The present application relates to the field of carbon emission accounting technology, and more specifically, to a carbon emission calculation method and system for railway infrastructure construction. Background Art

[0002] Against the backdrop of global climate change and growing awareness of environmental protection, reducing greenhouse gas emissions, particularly carbon dioxide (CO2), has become a major issue of widespread international concern. As a key mode of public transportation, the construction and maintenance of railway infrastructure plays an irreplaceable role in promoting economic development, improving transportation efficiency, and reducing carbon emissions from the transportation sector. However, with the continuous expansion and modernization of the railway network, carbon emissions from railway infrastructure construction have become increasingly prominent, becoming a significant constraint on the green development of the railway industry. Railway infrastructure construction, from material production and transportation to the use of machinery during construction, generates varying levels of greenhouse gas emissions, including CO2. Therefore, accurately calculating and assessing the carbon emissions of railway construction projects is crucial to achieving green building goals and reducing the environmental footprint.

[0003] Traditionally, carbon emissions calculations for railway infrastructure construction rely on empirical formulas or manual estimation methods based on static data. These methods often require extensive preliminary research and can lead to inaccurate or delayed results due to technical limitations or inaccurate information. Furthermore, in some cases, to save costs, improve competitiveness, or streamline approval processes, some railway construction projects may falsely report carbon emissions data, leading to an inability to properly assess the project's environmental impact, unnecessary waste of resources, or environmental pollution, and hindering the achievement of global climate governance goals.

[0004] Therefore, there is a need for a carbon emission calculation method and system for railway infrastructure construction. Summary of the Invention

Generally speaking, the terms "comprises" and "include" only indicate the inclusion of the steps and elements specifically identified, and these steps and elements do not constitute an exclusive list.

[0023] Although the present application makes various references to certain modules in the system according to embodiments of the present application, any number of different modules can be used and run on the user terminal and / or server. The modules are illustrative only, and different aspects of the system and method can use different modules.

[0024] Flowcharts are used in this application to illustrate the operations performed by the systems according to the embodiments of the present application. It should be understood that the preceding or following operations are not necessarily performed in exact order.

[0025] Below, the exemplary embodiments according to the present application will be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application, and it should be understood that the present application is not limited to the exemplary embodiments described herein.

[0026] It is worth noting that in this application, all actions to obtain data are carried out in compliance with the relevant data protection laws and policies of the country where they are located and with the authorization given by the owner of the corresponding device.

[0027] Figure 1 Flowchart of a carbon emission calculation method for railway infrastructure construction according to an embodiment of the present application. Figure 2 Schematic diagram of data flow for the carbon emission calculation method for railway infrastructure construction according to an embodiment of the present application. Figure 1 and Figure 2As shown, the carbon emission calculation method for railway infrastructure construction includes the following steps: S1, obtaining the basic data and total carbon emissions of the railway infrastructure to be verified uploaded by the user; S2, obtaining the historical carbon emission data of the railway infrastructure, wherein each data sample in the historical carbon emission data of the railway infrastructure is {basic data of the railway infrastructure, verified to be real carbon emissions}; S3, respectively performing structured coding on the basic data of the railway infrastructure to be verified and each data sample in the historical carbon emission data of the railway infrastructure to be verified to obtain a set of embedded coding vectors of the basic data of the railway infrastructure to be verified and embedded spliced ​​coding vectors of the basic data-carbon emissions; S4, performing dynamic semantic search based on a selected interval on the embedded coding vectors of the basic data of the railway infrastructure to be verified and the set of embedded spliced ​​coding vectors of the basic data-carbon emissions to obtain a query response coding vector of the railway infrastructure to be verified; S5, determining a reasonable estimate of carbon emissions based on the query response coding vector of the railway infrastructure to be verified; S6, determining whether the total carbon emissions of the railway infrastructure to be verified are real based on the reasonable estimate of carbon emissions.

[0028] In the aforementioned carbon emissions calculation method for railway infrastructure construction, step S1 obtains basic data and total carbon emissions uploaded by the user for the railway infrastructure to be verified. This basic data includes the classification of specific construction stages, the number and type of construction machinery and equipment, electricity consumption, and data related to material manufacturing and transportation. It should be understood that the basic data uploaded by the user for the railway infrastructure to be verified serves as the foundation for carbon emissions calculation. Different construction stages (e.g., earthwork, infrastructure construction, track laying, etc.) have different carbon emission sources and amounts. Understanding the classification of specific construction stages facilitates a more accurate carbon emissions estimate. Furthermore, different types of machinery and equipment consume different amounts of energy and generate different emissions during use. By obtaining the number and type of construction machinery and equipment, the total energy consumption and carbon emissions of construction machinery can be calculated. Furthermore, electricity consumption is an important indicator for assessing energy consumption during construction, while data related to material manufacturing and transportation covers the entire carbon emission chain from raw material production to the construction site and is crucial for a comprehensive carbon emissions calculation. Based on this, this application comprehensively considers various carbon emission factors during railway infrastructure construction to provide users with a more comprehensive and accurate carbon emissions calculation service.

[0029] Specifically, first, regarding the collection of classified information on specific construction phases, users are required to list each construction phase in detail, including but not limited to survey and design, civil engineering, track laying, and electrification installation, with clear timeframes for each phase. To facilitate subsequent processing, it is recommended to adopt a standardized construction phase classification system, such as the internationally recognized Building Information Modeling (BIM) standard or industry-specific project management guidelines. This helps ensure that all participants use consistent language to describe the construction process, improving data consistency and comparability.

[0030] Next, regarding the number and type of construction machinery and equipment, users are required to provide a detailed list of all machinery and equipment involved in the construction, such as excavators, loaders, bulldozers, and rollers. For each type of equipment, in addition to the number, parameters such as model, power, operating hours, and frequency of use should also be recorded. This information is crucial for calculating the carbon emissions generated during the operation of the machinery and equipment, as different types of machinery and equipment have different energy consumption characteristics and emission factors. Furthermore, users are encouraged to provide energy efficiency labels or environmental certification materials provided by the equipment manufacturer to more accurately assess CO2 emissions during machinery use.

[0031] Equally important is collecting electricity usage data. Users are required to submit detailed records of their electricity consumption, including both direct electricity use at the construction site and indirect electricity used to produce building materials. For direct electricity use, it is recommended to record daily or weekly usage in a time series, distinguishing between different daytime and nighttime patterns. For indirect electricity consumption, primarily related to electricity used in the manufacturing of building materials, this information may need to be obtained from suppliers, making the establishment of an effective supply chain communication mechanism crucial.

[0032] The collection of data related to material manufacturing and transportation involves a broader supply chain network. For material manufacturing, users should provide information on the production volume, production processes, and energy sources of major building materials such as concrete, steel, and asphalt. Data collection for transportation should not only consider the logistics process from the raw material production site to the processing location, but also the entire path of the finished materials from the processing plant to the construction site. To this end, users are required to provide information such as the type of transport vehicle, load capacity, distance traveled, fuel type, and any efforts to optimize transportation routes to reduce emissions.

[0033] In addition, to ensure the accuracy and completeness of all the above information, users are encouraged to use spreadsheets, database management systems or other digital tools to manage and submit data. This will not only improve data entry efficiency, but also automatically check data format and logical errors through built-in validation rules, further improving data quality.

[0034] In the above-mentioned carbon emission calculation method for railway infrastructure construction, the step S2 obtains the historical data of carbon emissions of railway infrastructure, and each data sample in the historical data of carbon emissions of railway infrastructure is {basic data of railway infrastructure, verified to be real carbon emissions}. Specifically, the carbon emission data of railway infrastructure in the historical period is further used to construct a reference sample set. Specifically, the present application retrieves a large amount of basic data of railway infrastructure and corresponding carbon emission data that has been verified to be real from the background database, and pairs the basic data of each railway infrastructure with the corresponding carbon emission data to form multiple data samples, so as to explore the potential laws and characteristics of carbon emissions under different construction conditions, thereby providing strong data support for the estimation of carbon emissions of the current railway infrastructure to be verified.

[0035] Specifically, in order to create a data sample set that includes basic data on railway infrastructure and verified real carbon emissions, it is necessary to first determine the specific type of information required, such as specific construction stage classification, the number and type of construction machinery and equipment, electricity consumption, material manufacturing and transportation related data, etc., while clarifying the time range and geographical area restrictions.

[0036] Ideally, data sources should include public data released by official statistical agencies, audited reports provided by government or industry regulators, research findings from scientific research institutions, and voluntary submissions from companies involved in railway construction. Data collected from these channels tends to be highly authoritative and reliable. Furthermore, international cooperation and exchange are encouraged to obtain carbon emissions data from similar projects in other countries and regions to enrich the database. For each data source, detailed documentation of the acquisition method, access rights requirements, and terms of use should be maintained to ensure legal and compliant operations.

[0037] It's crucial to establish a standardized data collection process for selected data sources. This includes designing a unified data form template, specifying required fields and their formatting requirements; developing automated tools to assist with data capture and preprocessing to reduce human error; and establishing a dedicated team to communicate and coordinate with all data providers to ensure timely and high-quality data submission. To ensure consistency across data sources, it's particularly important to adopt internationally recognized standards and protocols, such as the ISO 14064 greenhouse gas accounting standard, as the basic framework for data collection.

[0038] Data quality control is a key link in ensuring the reliability of historical data. To this end, a multi-level quality inspection system can be established, covering three stages: preliminary screening, in-depth verification, and expert review. The preliminary screening stage mainly eliminates data entries that obviously do not meet the requirements or have major defects, such as missing necessary fields, abnormally large or small values, etc. In-depth verification relies on computer algorithms and statistical models to conduct logical consistency tests, trend analysis, and outlier detection on the data. Any problems found will be promptly fed back to the original data provider for clarification or correction. Finally, in the expert review stage, professionals from various fields such as environmental science and engineering are invited to form a review panel to conduct a comprehensive review of the data after the first two rounds of screening, especially for the interpretation and confirmation of some complex technical parameters and professional terms.

[0039] Next, all quality-controlled data will be consolidated into a structured database, where each data sample consists of basic data on railway infrastructure and corresponding carbon emissions. To facilitate subsequent use, the database should include powerful search capabilities and flexible data extraction interfaces, allowing users to query required information based on specific criteria. Furthermore, given the importance of data security and privacy protection, the database must also implement strict access control measures, ensuring that only authorized personnel can view and manipulate sensitive content.

[0040] In the above-mentioned carbon emission calculation method for railway infrastructure construction, the step S3 is to perform structured coding on each data sample in the basic data of the railway infrastructure to be verified and the historical data of carbon emissions of the railway infrastructure to obtain a set of embedded coding vectors of the basic data of the railway infrastructure to be verified and a set of embedded spliced ​​coding vectors of the basic data-carbon emissions. It should be understood that, considering that the basic data and carbon emissions data of the railway infrastructure usually exist in various forms such as text and numerical values, it is difficult to directly perform efficient calculations and comparisons. Therefore, this application adopts an embedded coding technology based on deep learning to perform structured processing on each data sample in the basic data of the railway infrastructure to be verified and the historical data of carbon emissions of the railway infrastructure to map different types of discrete or continuous data into a low-dimensional dense vector space while retaining the semantic information of the data, thereby obtaining a set of embedded coding vectors of the basic data of the railway infrastructure to be verified and a set of embedded spliced ​​coding vectors of the basic data-carbon emissions with a unified structure. In addition, through embedded coding, basic data with similar semantic features can be close to each other in the vector space, while basic data with different semantic features can be far away from each other, thereby revealing the inherent correlation between the data and providing a more effective semantic basis for subsequent carbon emissions estimation. Specifically, for the basic data of the railway infrastructure to be verified, different embedding coding strategies are required for different types of data. For example, discrete categorical data such as the classification of specific construction stages, types of construction machinery and equipment, and material names can be encoded using one-hot encoding techniques. Continuous numerical data such as the number of construction machinery and equipment, electricity consumption, and material transportation distance can be encoded using methods such as numerical embedding or normalization. This ensures that different types of basic data can be effectively converted into vector form, and through vector splicing, a complete embedded coding vector for the basic data of the railway infrastructure to be verified is obtained. Similarly, for each data sample in the historical carbon emission data of railway infrastructure, the basic data and the corresponding carbon emission data are separately subjected to the above-mentioned structured coding to obtain an embedded vector representation of the basic data and an embedded vector representation of the carbon emissions. Through vector splicing, a basic data-carbon emission embedded splicing coding vector is formed, thereby constructing an association representation between the basic data of railway infrastructure and carbon emissions.

[0041] In the above-mentioned carbon emission calculation method for railway infrastructure construction, the step S4 performs a dynamic semantic search based on the selection interval on the set of the embedded coding vector of the basic data of the railway infrastructure to be verified and the embedded spliced ​​coding vector of the basic data-carbon emissions to obtain the query response coding vector of the railway infrastructure to be verified. It should be understood that the present application takes into account that some data samples in the historical data of carbon emissions of the railway infrastructure may be quite different from the basic data of the railway infrastructure to be verified. If a matching analysis is performed directly, not only will the amount of calculation be large, but it may also interfere with the final carbon emissions estimation result. Therefore, in order to accurately filter out the samples that are most matched or similar to the current basic data to be verified from the historical data, the present application proposes a dynamic semantic search coding method, which performs a preliminary semantic association analysis on the set of embedded coding vectors of the basic data of the railway infrastructure to be verified and the embedded spliced ​​coding vector of the basic data-carbon emissions to determine a reasonable feature selection range, and uses this as an anchor point to perform refined semantic query matching analysis, thereby improving search efficiency and matching accuracy. Among them, Figure 3 Flowchart of sub-step S4 of the carbon emission calculation method for railway infrastructure construction according to an embodiment of the present application. Figure 3 As shown, the step S4 includes the steps of: S41, determining the historical basic data selection range ratio based on the internal correlation between the basic data embedded coding vector of the railway infrastructure to be verified and each basic data-carbon emissions embedded splicing coding vector in the set of basic data-carbon emissions embedded splicing coding vectors; S42, based on the historical basic data selection range ratio, performing semantic query response coding on the basic data embedded coding vector of the railway infrastructure to be verified and the set of basic data-carbon emissions embedded splicing coding vectors to obtain the query response coding vector of the railway infrastructure to be verified.

[0042] Figure 4 FIG4 is a flowchart of sub-step S41 of the carbon emission calculation method for railway infrastructure construction according to an embodiment of the present application. Figure 4 As shown, the step S41 includes the steps of: S411, calculating the internal relationship score value of the embedded coding vector of the basic data of the railway infrastructure to be verified relative to each basic data-carbon emissions embedded splicing coding vector in the set of the basic data-carbon emissions embedded splicing coding vector to obtain a set of internal relationship score values ​​of the basic data to be verified-historical basic data; S412, using the basic data-carbon emissions embedded splicing coding vector corresponding to the maximum value in the set of internal relationship score values ​​of the basic data to be verified-historical basic data as the basic data-carbon emissions dynamic search anchor vector; S413, determining the historical basic data selection range ratio based on the characteristic distribution characteristics of the basic data-carbon emissions dynamic search anchor vector.

[0043] More specifically, step S411 is expressed as follows: ; ; in, is the basic data - the set of embedded concatenated coding vectors of carbon emissions, 、 、 、 They are the first, second, and third in the set of basic data-carbon emissions embedded concatenated coding vectors. and Basic data - carbon emissions embedded in the concatenated coding vector, is the embedded coding vector of the basic data of the railway infrastructure to be verified, and They are the weight parameter matrix of historical basic data and the weight parameter matrix of basic data to be verified, is the hyperbolic tangent activation function, is the transposed vector of the internal relationship score reference vector between the basic data to be verified and the historical basic data. For the The corresponding score value of the internal relationship between the basic data to be verified and the historical basic data.

[0044] More specifically, step S412 is expressed as follows: ; in, Indicates extracting the basic data-carbon emissions embedding concatenation coding vector corresponding to the maximum value in the set of internal relationship scores of the basic data to be verified and the historical basic data, Dynamically search for anchor vectors for basic data - carbon emissions.

[0045] Specifically, a neural network model is first used to perform feature association analysis and internal relationship scoring on the embedded coding vectors of the basic data of the railway infrastructure to be verified and the embedded spliced ​​coding vectors of each basic data-carbon emissions to evaluate the information relevance and degree of association between the basic data to be verified and the historical basic data. It should be understood that the higher the internal relationship score value, the more similar the data features between the two are. Therefore, the present application further selects the basic data-carbon emissions embedded spliced ​​coding vector with the highest score value from the set of basic data-carbon emissions embedded spliced ​​coding vectors as the benchmark for comparative analysis based on the obtained internal relationship score values, and defines it as the basic data-carbon emissions dynamic search anchor vector. In this way, by screening out the historical basic data samples that are most similar to the basic data to be verified as the anchor point for subsequent feature comparative analysis, it helps to improve the accuracy and reliability of the feature comparative analysis.

[0046] More specifically, step S413 determines the historical basic data selection range ratio based on the characteristic distribution characteristics of the basic data-carbon emissions dynamic search anchor vector. In a specific example of the present application, the vector at the starting position of the historical basic data selection range ratio is the basic data-carbon emissions dynamic search anchor vector, and each basic data-carbon emissions embedded splicing code vector in the historical basic data selection range ratio is defined as a dynamic search optimized basic data-carbon emissions embedded splicing code vector, which is expressed as follows: ; ; in, 、 and They represent the maximum eigenvalue, eigenmean and eigenvariance of the basic data-carbon emissions dynamic search anchor vector, is a very small positive number, used to prevent the denominator from being 0. Indicates rounding up operation. Select the window size of the range ratio for the historical base data, The vector for selecting the starting position of the range ratio for the historical basic data is , A vector for selecting the end position of the range ratio for the historical basic data, A set of dynamic search optimization basic data-carbon emissions embedded concatenated coding vectors is selected for each range ratio of the historical basic data.

[0047] Specifically, considering that relying solely on a single similar data sample for feature comparison analysis may result in inaccurate carbon emissions estimation results due to the limitations of data features. Therefore, the present application further uses the basic data-carbon emissions dynamic search anchor vector as the starting position, and based on the characteristic distribution characteristics of the basic data-carbon emissions dynamic search anchor vector, calculates the selection range ratio of the historical basic data, thereby selecting multiple basic data-carbon emissions embedded splicing coding vectors from the set of basic data-carbon emissions embedded splicing coding vectors as candidate samples for comparison analysis, and constructing a set of dynamic search optimization basic data-carbon emissions embedded splicing coding vectors. In this way, by limiting the data range of the comparative analysis, not only can the amount of calculation be reduced and the efficiency of carbon emissions estimation be improved, but it can also focus on the historical basic data samples that are most similar to the basic data to be verified, thereby avoiding analysis errors caused by a single data sample.

[0048] Specifically, in a specific example of the present application, step S42 includes: inputting the embedded coding vector of the railway infrastructure basic data to be verified and the embedded spliced ​​coding vectors of each dynamic search optimization basic data-carbon emission in the historical basic data selection range ratio into the dynamic semantic search encoder to obtain the query response coding vector of the railway infrastructure to be verified, which is expressed as follows: ; ; in, is the modulus of the vector, for and The cosine similarity between A query response encoding vector for the railway infrastructure to be verified.

[0049] Specifically, feature difference calculations are performed on the embedded coding vectors of the basic data of the railway infrastructure to be verified and the embedded spliced ​​coding vectors of each dynamically searched optimized basic data-carbon emissions in the selection range to extract the feature differences between the basic data to be verified and the historical basic data, and the feature similarity between the two is used as a weight coefficient to perform weighted aggregation on the feature difference information to comprehensively consider the difference information of the basic data to be verified relative to the reference sample, and further the difference information between the basic data to be verified and the reference sample data is fused with the basic data-carbon emissions dynamic search anchor vector to generate the final query response coding vector for the railway infrastructure to be verified. In this way, the inherent characteristics of the basic data of the railway infrastructure to be verified are taken into account, and the most similar reference data sample is used as the basis, so that the actual situation of the railway infrastructure to be verified can be more comprehensively reflected, providing a more comprehensive and reliable basis for the subsequent accurate estimation of carbon emissions.

[0050] In the above-mentioned carbon emission calculation method for railway infrastructure construction, the step S5 determines a reasonable estimate of carbon emissions based on the query response coding vector of the railway infrastructure to be verified. In a specific example of the present application, the step S5 includes: inputting the query response coding vector of the railway infrastructure to be verified into a decoder-based carbon emission estimation module to obtain the reasonable estimate of carbon emissions. Specifically, the decoder is based on a neural network architecture. After receiving the query response coding vector of the railway infrastructure to be verified as input, it fully learns and utilizes the inherent characteristics of the basic data to be verified implied in the vector and the correlation information between it and the historical reference data through layer-by-layer decoding operations, and gradually parses out the reasonable estimate of carbon emissions corresponding to the basic data of the railway infrastructure to be verified, thereby providing a quantitative basis for the carbon emission management of railway infrastructure.

[0051] Among them, since the set of the embedded coding vector of the basic data of the railway infrastructure to be verified and the set of the basic data-carbon emissions embedded splicing coding vectors respectively represent the low-dimensional embedded coding features of the basic data of the railway infrastructure to be verified and the embedded coding features of the historical data of the railway infrastructure carbon emissions, when performing feature dynamic semantic search encoding based on the selection range ratio anchoring, the feature population attributes of different semantics will have dynamic semantic search fairness differences based on the selection range ratio anchoring level, thereby affecting the coding feature distribution response inclusiveness of the query response coding vector of the railway infrastructure to be verified, and reducing the accuracy of the reasonable carbon emissions estimate obtained by inputting the decoder-based carbon emissions estimation module.

[0052] In a preferred example, inputting the to-be-verified railway infrastructure query response code vector into a decoder-based carbon emissions estimation module to obtain a reasonable estimate of carbon emissions includes: Arranging the railway infrastructure query response code vectors to be verified in ascending order according to the eigenvalues ​​to obtain railway infrastructure query response ascending code vectors to be verified; Determine the mean of the eigenvalues ​​corresponding to the ascending code vector of the query response to be verified railway infrastructure and the standard deviation of the eigenvalues The first railway infrastructure query response coding statistical modulation vector to be verified is obtained by multiplying the ascending coding vector of the railway infrastructure query response to be verified by the point-wise subtraction vector of the eigenvalue mean and the eigenvalue standard deviation, that is: ; in, and represent the eigenvalue mean and eigenvalue standard deviation corresponding to the ascending coded vector of the railway infrastructure query response to be verified, respectively, represents the ascending code vector of the query response to the railway infrastructure to be verified, Indicates point reduction, represents dot product, represents a first railway infrastructure query response coding statistical modulation vector to be verified; The second railway infrastructure query response coding statistical modulation vector to be verified is obtained by multiplying the point-wise subtraction vector of the ascending coding vector of the to-be-verified railway infrastructure query response and the eigenvalue standard deviation by the eigenvalue mean, that is: ; in, represents a second railway infrastructure query response coding statistical modulation vector to be verified; After multiplying the bit-by-bit inverse of the second railway infrastructure query response coding statistical modulation vector by the first railway infrastructure query response coding statistical modulation vector, taking the bit-by-bit logarithm with base 2 to obtain the query response coding neuron granularity optimization vector, that is: ; in, represents the bit-by-bit inverse of the second railway infrastructure query response coded statistical modulation vector to be verified, that is, the inverse of the eigenvalue of each position of the second railway infrastructure query response coded statistical modulation vector to be verified is calculated, Represents the query response encoding neuron granularity optimization vector; The mean of the eigenvalues Divide by the standard deviation of the eigenvalue The square root of the quotient is multiplied by the weight hyperparameter, and then the optimized query response encoding neuron granularity optimization vector point is added to obtain the optimized railway infrastructure query response encoding vector to be verified, that is: ; in, represents the weighted hyperparameter, represents an optimized railway infrastructure query response encoding vector to be verified; The optimized railway infrastructure query response code vector to be verified is input into a decoder-based carbon emissions estimation module to obtain a reasonable estimate of carbon emissions.

[0053] Therefore, considering the attribute-level fairness differences of the data population corresponding to the serial response fusion features of the railway infrastructure query response code vector to be verified, in order to improve the response inclusiveness under the feature distribution diversity of the railway infrastructure query response code vector to be verified, in the technical solution of the present application, by mapping the serialized signal of the railway infrastructure query response code vector to be verified into a synaptic connection network defined by statistical features, a meaningful measurement of the activation association of the neural pattern set within the synchronization field can be achieved. Based on this, a neural activity space with independent activation channels is constructed through synaptic plasticity adjustment with neuronal responses, and synaptic pruning optimization is performed within the neural activity space of the multi-layer neural network of neuronal responses based on signal queries. In this way, a robust distribution fairness unified representation of the railway infrastructure query response code vector to be verified is achieved, thereby improving the accuracy of the reasonable carbon emission estimate obtained by its input to the decoder-based carbon emission estimation module.

[0054] In the above-mentioned carbon emission calculation method for railway infrastructure construction, the step S6 determines whether the total carbon emissions of the railway infrastructure to be verified are true based on the reasonable estimate of carbon emissions. In a specific example of the present application, the step S6 includes: calculating the difference between the reasonable estimate of carbon emissions and the total carbon emissions of the railway infrastructure to be verified as a carbon emissions deviation value; and determining whether the total carbon emissions of the railway infrastructure to be verified are true based on the comparison between the carbon emissions deviation value and a preset threshold value. Specifically, in order to measure the degree of difference between the total carbon emissions declared by the user and the reasonable carbon emissions estimated based on the reference sample, the present application further calculates the difference between the reasonable estimate of carbon emissions and the total carbon emissions of the railway infrastructure to be verified as a carbon emissions deviation value, and determines whether the total carbon emissions declared by the user are true by comparing the carbon emissions deviation value with the preset threshold value, thereby achieving effective verification of carbon emission data during railway infrastructure construction and ensuring the authenticity and reliability of carbon emission data. Specifically, if the carbon emissions deviation value is less than the preset threshold, the user's reported total carbon emissions are considered to be relatively realistic and close to reasonable estimates based on historical data, indicating that the railway infrastructure's carbon emissions management is relatively standardized. Conversely, if the carbon emissions deviation value is greater than or equal to the preset threshold, it may indicate that the user's reported total carbon emissions are abnormal and require further verification and validation. In this way, not only can errors in carbon emissions data be discovered and corrected in a timely manner, but it can also strengthen supervision of railway infrastructure carbon emissions management and promote the railway industry to achieve low-carbon, green, and sustainable development.

[0055] In summary, the carbon emission calculation method for railway infrastructure construction based on the embodiment of the present application is explained. It first retrieves the basic data of the railway infrastructure and the corresponding verified carbon emissions from the background database to construct a reference sample set, and uses deep learning-based data processing technology to embed the basic data of the railway infrastructure to be verified uploaded by the user and each reference sample for encoding and dynamic semantic search. Based on the semantic query response information between the basic data to be verified and each reference sample, the reasonable carbon emissions of the railway infrastructure to be verified are intelligently estimated, and then based on this, it is judged whether the total carbon emissions of the railway infrastructure to be verified uploaded by the user are true. In this way, the carbon emissions during the construction of the railway infrastructure can be quickly and accurately calculated and verified, false declarations can be avoided, and the authenticity and reliability of carbon emission data can be improved.
