[0032] Among the related technologies, the carbon emission accounting of locomotives is mainly done manually, which not only results in low efficiency in data collection and calculation, but also in insufficient accuracy of the accounting results.
[0033] In view of this, an exemplary embodiment of this disclosure provides a method for calculating the carbon emissions of a locomotive. This method receives the entire lifecycle data of the locomotive and then inputs this data into a carbon emission calculation model to obtain the locomotive's carbon emission data. The carbon emission calculation model includes a first calculation model for calculating the carbon emissions of each subsystem of the locomotive during the design process, a second calculation model for calculating the carbon emissions of each subsystem of the locomotive during the production process, and a third calculation model for calculating the carbon emissions of the entire locomotive system during operation.
[0034] As can be seen, in this embodiment of the disclosure, the carbon emission accounting model can not only calculate the carbon emissions of the locomotive during operation, but also calculate the carbon emissions of each subsystem of the locomotive during production and design, thereby realizing the calculation of carbon emissions throughout the entire life cycle of the locomotive. Moreover, since the calculation is carried out through the carbon emission accounting model, no manual operation is required, which greatly improves the calculation efficiency and accuracy.
[0035] To better understand the technical solutions provided in the embodiments of this disclosure, the following is a brief introduction to the application scenarios applicable to the technical solutions provided in the embodiments of this disclosure. It should be noted that the application scenarios described below are only for illustrating the embodiments of this disclosure and are not intended to limit the scope. In specific implementation, the technical solutions provided in the embodiments of this disclosure can be flexibly applied according to actual needs.
[0036] In this embodiment of the disclosure, the locomotive carbon emission accounting technology can be applied to any business scenario that requires carbon emission accounting for electric locomotives, and this embodiment of the disclosure does not limit it.
[0037] Please see Figure 1 As shown, Figure 1 This is an application scenario to which the technical solution of this disclosure embodiment can be applied. The schematic diagram of this scenario includes multiple data acquisition devices 101 and electronic devices 102. Among them, data acquisition devices 101-1, 101-2, ..., 101-n can collect data from different models of locomotives, thereby providing carbon emission accounting services for multiple different models of electric locomotives.
[0038] The data acquisition device 101 and the electronic device 102, as well as the data acquisition devices 101, can be directly or indirectly connected through one or more networks 103.
[0039] In this embodiment, the user can identify the electric locomotive to be tested and control the data acquisition device 101 to collect the entire lifecycle data of the electric locomotive. The data acquisition device 101 can then send the collected lifecycle data to the electronic device 102. The electronic device 102 can receive the lifecycle data and input it into a carbon emission accounting model to obtain the locomotive's carbon emission data. The carbon emission accounting model includes a first accounting model for calculating the carbon emissions of each subsystem of the locomotive during the design process, a second accounting model for calculating the carbon emissions of each subsystem of the locomotive during the production process, and a third accounting model for calculating the carbon emissions of the entire locomotive system during operation. Optionally, the electronic device 102 can send a data acquisition command to the data acquisition device 101 to receive the lifecycle data of the locomotive sent by the data acquisition device 101.
[0040] as well as, Figure 1The electronic device 102 can be an independent physical server, a server cluster or distributed system composed of multiple physical servers, or a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communication, middleware services, domain name services, security services, content delivery networks (CDN), and big data and artificial intelligence platforms, but it is not limited to these.
[0041] Of course, the methods provided in this disclosure are not limited to... Figure 1 The application scenarios shown can also be used in other possible application scenarios, such as the application scenario where only electronic devices implement the carbon emission accounting method for electric locomotives. This disclosure does not limit the application scenarios.
[0042] Please see Figure 2 , Figure 2 This is a schematic flowchart illustrating a carbon emission accounting method for an electric locomotive according to an embodiment of this disclosure. The method can be executed, for example, by an electronic device, which can be... Figure 1 The specific implementation process of this method for electronic device 102 is as follows: Step 201: Receive the full lifecycle data of the locomotive.
[0043] Step 202: Input the full life cycle data into the carbon emission accounting model to obtain the locomotive's carbon emission data; wherein, the carbon emission accounting model includes a first accounting model for calculating the carbon emissions of each subsystem of the locomotive during the design process, a second accounting model for calculating the carbon emissions of each subsystem of the locomotive during the production process, and a third accounting model for calculating the carbon emissions of the entire locomotive system during operation.
[0044] As can be seen, in this embodiment of the disclosure, the carbon emission accounting model can not only calculate the carbon emissions of the locomotive during operation, but also calculate the carbon emissions of each subsystem of the locomotive during production and design, thereby realizing the calculation of carbon emissions throughout the entire life cycle of the locomotive. Moreover, since the calculation is carried out through the carbon emission accounting model, no manual operation is required, which greatly improves the calculation efficiency and accuracy.
[0045] The following is about Figure 2 Each step in the process will be explained in detail.
[0046] In step 201, the full lifecycle data of the locomotive is received.
[0047] In this embodiment of the disclosure, the full lifecycle data of the locomotive sent by the acquisition device can be obtained. Alternatively, the electronic device can first trigger the acquisition command and then obtain the full lifecycle data of the locomotive collected by the acquisition device based on the acquisition command. This embodiment of the disclosure does not limit the method of obtaining the full lifecycle data of the locomotive.
[0048] In this disclosure, the locomotive's full lifecycle data includes data such as the raw materials and energy consumption of each component or subsystem of the locomotive, but this disclosure does not limit this aspect.
[0049] For example, an electric locomotive of type A includes several subsystems such as the car body system (car body, coupling device), bogie (frame structure, wheelset composition, primary suspension, secondary suspension), ventilation system (ventilation and cooling chain, traction motor fan), traction system (traction transformer, traction auxiliary converter cabinet, traction motor), braking system, overall system, and digital network. Therefore, an electric locomotive of type A can include data such as the raw materials and energy consumption of the car body system, bogie, ventilation system, traction system, and braking system.
[0050] Step 202: Input the full life cycle data into the carbon emission accounting model to obtain the locomotive's carbon emission data; wherein, the carbon emission accounting model includes a first accounting model for calculating the carbon emissions of each subsystem of the locomotive during the design process, a second accounting model for calculating the carbon emissions of each subsystem of the locomotive during the production process, and a third accounting model for calculating the carbon emissions of the entire locomotive system during operation.
[0051] In this embodiment of the disclosure, after the electronic device obtains full lifecycle data, it can input the full lifecycle data into the carbon emission accounting model to obtain the locomotive's carbon emission data. In other words, the carbon emission data of the locomotive throughout its entire lifecycle, from design and production to operation, can be obtained automatically and efficiently based directly on the carbon emission accounting model.
[0052] In this embodiment of the disclosure, before introducing the scheme for processing the full life cycle data of locomotives based on the carbon emission accounting model, the process of obtaining the carbon emission accounting model will be introduced first.
[0053] In this embodiment, the full lifecycle data of multiple different models of electric locomotives can be acquired, such as the full lifecycle data of model A, model B, and model C. Furthermore, first carbon emission data, second carbon emission data, and third carbon emission data corresponding to multiple different models of electric locomotives, as well as total carbon emission data, can be acquired. Further, the data (i.e., full lifecycle data and carbon emission data) of the aforementioned different models of electric locomotives can be preprocessed, such as data cleaning and tagging, which is not limited in this embodiment. This allows for the acquisition of a training sample set for a preset carbon emission accounting model.
[0054] In this embodiment, the full lifecycle data of the training samples in the aforementioned training sample set can be input into a preset carbon emission accounting model to obtain predicted carbon emission data. Based on this predicted carbon emission data, the carbon emission data labeled in the training samples, and a preset loss function, a loss value is determined. The preset carbon emission accounting model is then adjusted based on this loss value until the comparison result meets a preset condition, such as the loss value being less than a preset threshold. This results in a trained carbon emission accounting model. The preset loss function may include sub-loss functions corresponding to the first accounting model, the second accounting model, and the third accounting model. Based on these three sub-loss functions, an overall loss function is determined, and the preset carbon emission model is adjusted based on this overall loss function.
[0055] In the embodiments disclosed herein, the preset carbon emission accounting model can be constructed based on at least one neural network such as Convolutional Neural Network (CNN), Recurrent Neural Network (RNN) and its variants, Backpropagation (BP) neural network, etc., and this application embodiment does not limit it.
[0056] In this embodiment of the disclosure, after obtaining the trained carbon emission accounting model, see [link to relevant documentation]. Figure 3 As shown, the following steps, but not limited to, can be used to obtain locomotive carbon emission data: Step 301: Divide the full lifecycle data into first-stage data, second-stage data, and third-stage data.
[0057] In this embodiment of the disclosure, the carbon emission accounting model can first divide the entire lifecycle data, for example, according to three stages: design stage, production stage, and operation stage, to obtain first-stage data, second-stage data, and third-stage data. In other words, the first-stage data can be understood as data from the locomotive design stage, the second-stage data as data from the locomotive production stage, and the third-stage data as data from the locomotive operation stage.
[0058] Step 302: Input the first stage data into the first accounting model to obtain the first carbon emission data.
[0059] In this embodiment, the first-stage data can be divided according to a preset division method to obtain multiple first sub-data. Then, based on these multiple first sub-data, the carbon emission data for each first sub-data can be determined. Further, the first carbon emission data can be obtained based on the carbon emission data of each first sub-data. Optionally, each first sub-data can be classified according to the corresponding system boundaries and functional units of material acquisition and transportation to obtain material category information for each first sub-data. Then, based on the material category information, quantity information, and carbon emission factor of the first sub-data, the carbon emission data for the first sub-data can be determined. The carbon emission factor can be determined based on the rules governing various raw materials within their corresponding rows; this embodiment does not limit this determination.
[0060] In this embodiment, the first-stage data can be divided based on the attribute information of the sub-data within it. The attribute information of the sub-data characterizes which sub-data belongs to any subsystem of the locomotive, including the bogie, car body, electrical, braking, overall system, and digital network, thus obtaining the first sub-data for each subsystem. Then, based on the characteristics of each subsystem, the system boundaries and functional units for raw material acquisition and transportation can be determined. The system boundaries can be understood as the stages that each subsystem needs to be included in the accounting process; for example, the bogie design stage needs to specify raw material transportation and finished vehicle delivery. The functional units can be understood as a set unified measurement standard, i.e., an accounting unit, which can be determined based on actual implementation; this embodiment does not limit this.
[0061] In this embodiment, the first sub-data, i.e., raw material data, can be classified according to the defined system boundaries and functional units of each subsystem's components. The raw material categories include, but are not limited to, metals, glass products, carbon steel, rubber, polymers, liquids, and gases, thus obtaining material category information. Furthermore, the quantity of raw materials required by each subsystem of the locomotive can be combined with the carbon emission factors of each type of raw material within the industry to perform cumulative calculations, thereby obtaining carbon emission data for each subsystem's design stage, and ultimately, carbon emission data for the locomotive's design stage.
[0062] For example, the first sub-data of the bogie includes data on components such as the frame structure (carbon steel frame), wheelset components (axles, wheels, axle housings, gears, and gearboxes), primary suspension (springs), and secondary suspension (rubber stacks). The material type for the frame structure, springs, axles, wheels, axle housings, gears, and gearboxes is carbon steel; the material type for the rubber stacks is rubber. Further, the design weights of the frame structure, springs, axles, wheels, axle housings, gears, gearboxes, and rubber stacks can be determined. Then, based on the design weights, material type information, and carbon emission factors of various raw materials in the industry, the carbon emission data for the frame structure, springs, axles, wheels, axle housings, gears, gearboxes, and rubber stacks can be determined. Finally, the carbon emission data of the bogie is determined based on the sum of the aforementioned carbon emission data.
[0063] Step 303: Input the second-stage data into the second accounting model to obtain the second carbon emission data.
[0064] In this embodiment, the second-stage data can be divided according to a preset division method to obtain multiple second sub-data. These second sub-data include electricity consumption, gas consumption, coal consumption, and various process consumables. Then, based on the second sub-data and the energy carbon emission industry standard table, the second carbon emission data is determined. The energy carbon emission industry standard table can be determined based on the latest regulations of each industry; that is, the energy carbon emission industry standard table is updatable and is the most up-to-date when determining the second carbon emission data. For example, if carbon emission accounting for locomotive A is triggered on November 4, 2025, the latest energy carbon emission industry standard table prior to November 4, 2025, can be obtained, and the carbon emission accounting for locomotive A can be calculated based on this table.
[0065] In this embodiment of the disclosure, the aforementioned preset division method is to divide the data according to the attribute information of the sub-data in the data; the attribute information of the sub-data is used to characterize that the sub-data belongs to any subsystem of the locomotive, such as bogie, car body, electrical, braking, overall and digital network.
[0066] In this embodiment, for the second-stage data, the first-stage data can be divided based on the attribute information of the sub-data within the second-stage data. The attribute information of the sub-data is used to characterize whether the sub-data belongs to any subsystem of the locomotive, including the bogie, car body, electrical, braking, overall system, and digital network. This allows for the acquisition of second sub-data for each subsystem. Then, based on the characteristics of each subsystem during the product production stage, the energy consumption for carbon emissions of each subsystem can be identified. Energy consumption includes, but is not limited to, electricity consumption, gas consumption, coal consumption, and various process consumables. Furthermore, the carbon emissions from the energy consumed by each subsystem during the production stage can be calculated according to industry standards to determine the second carbon emission data.
[0067] Step 304: Input the third-stage data into the third accounting model to obtain the third carbon emission data.
[0068] In this embodiment, the accounting boundaries and functional units of the locomotive during the transportation, product operation, product maintenance, and product disposal phases can be determined. The definitions of the accounting boundaries and functional units can be found in the preceding description; the specific content of the boundaries and units can be determined based on actual implementation, and this embodiment does not impose any limitations on this. Then, based on the third-stage data, the accounting boundaries, and the functional units, the carbon emission item data of the locomotive during the transportation, product operation, product maintenance, and product disposal phases are determined. Further, the third carbon emission data can be determined based on the obtained carbon emission item data for each phase and the accounting standard information.
[0069] Step 305: Determine the locomotive's carbon emission data based on the first carbon emission data, the second carbon emission data, and the third carbon emission data.
[0070] In this embodiment of the disclosure, after obtaining the first carbon emission data, the second carbon emission data, and the third carbon emission data, that is, the carbon emission data of the locomotive during the design, production, and operation phases, the sum of the aforementioned carbon emission data can be used as the carbon emission data of the locomotive, that is, the carbon emission data of the locomotive throughout its entire life cycle can be determined.
[0071] In this embodiment, once the carbon emission data of the locomotive throughout its entire lifecycle is obtained, the carbon emission data can be displayed and processed. For example, it can provide data support for government departments to formulate carbon reduction targets and carbon emission quota allocation policies in the rail transit sector; it can help locomotive operating companies identify hot spots in carbon emissions throughout the entire lifecycle, formulate targeted emission reduction strategies, and use them for corporate carbon cost accounting and management, improve low-carbon operation management, enhance market competitiveness, and thus optimize corporate operations. Of course, it can also be used for locomotive technology research and development and product upgrades based on carbon emission data, etc., but this embodiment does not limit these aspects.
[0072] Exemplary embodiments of this disclosure also provide a carbon emission accounting device for electric locomotives. (See reference...)
