[0016] The embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0017] FIG1 is a flow chart of a method for calculating carbon emissions according to an embodiment of the present application. As shown in FIG1 , the method 100 for calculating carbon emissions includes:

[0018] Step 101: Establish a production simulation model.

[0019] A production simulation model is established based on production order information, a bill of material (BOM), a bill of process (BOP), and production resources. The BOP includes process steps and process time, and production resources include equipment and transportation. Optionally, the production simulation model can be a simulation of a real factory's production system, reflecting relevant information such as processes, production, and procedures. Specifically, it includes factory layout simulation, logistics simulation, and process simulation. In one embodiment, a factory simulation model is first established. The factory simulation model includes multiple production resources and the topological relationships between them. Production resources include equipment and transportation, including conveyor belts, transport vehicles, or trucks. Users can also configure corresponding transmission parameters based on the actual performance of the factory. Next, the factory simulation model configures energy usage parameters, process time, and direct carbon emissions per unit time for production resources in different states when processing preset workpieces. Energy usage parameters include: electrical energy consumption per unit time, steam consumption per unit time, or hot water consumption per unit time. Process time includes processing time, reset time, and recovery time. Different states include: working, waiting, standby, stagnant, power increase, and power reduction. Thirdly, according to the production order information, the types and quantities of raw materials are determined in the factory simulation model to obtain a production simulation model.

[0020] Step 102 : Map the unit energy consumption of raw materials and production resources involved in the production simulation model to corresponding data in the carbon emission factor database to obtain the carbon emission factor of raw materials and the carbon emission factor of production resources.

[0021] The carbon emission factor of raw materials / production resources refers to the emission coefficient of carbon dioxide (CO2) during the relevant use of raw materials / production resources. For example, the amount of CO2 emissions involved in the consumption of each unit of raw materials is the carbon emission factor of the corresponding raw materials.

[0022] Step 103: simulate and run the production simulation model.

[0023] Step 104 , counting the direct carbon emissions of production resources, the consumption of raw materials, and the energy consumption of production resources within a preset time period.

[0024] Among them, the energy consumption of production resources includes: electricity, steam or hot water.

[0025] Step 105 , obtaining the total carbon emissions of production resources within a preset time period based on the direct carbon emissions of production resources, the consumption of raw materials and the energy consumption of production resources, as well as the carbon emission factors of raw materials and production resources.

[0026] Among them, direct carbon emissions of production resources refer to the equivalent CO2 emissions converted from greenhouse gas emissions caused by the combustion of fossil fuels or related gas emissions involved in the operation of production resources.

[0027] Optionally, the total carbon emissions of production resources can be obtained by adding the direct carbon emissions of production resources + the consumption of raw materials × the carbon emission factor of raw materials + the energy consumption of production resources × the carbon emission factor of production resources within a preset time period.

[0028] The present application embodiment provides a method for dynamically calculating carbon emissions related to production resources. Based on the simulation of a production simulation model, the unit energy consumption of each unit raw material and production resource is mapped to a carbon emission factor database to obtain the corresponding carbon emission factors. The direct carbon emissions of production resources within a preset time period, the carbon emissions corresponding to the energy consumption of production resources, and the carbon emissions corresponding to the consumed raw materials are then accumulated to obtain the total carbon emissions of production resources. Through the present application embodiment, the carbon emissions of production resources in different time periods can be quickly and accurately reflected, helping users to achieve carbon emission management of factories.

[0029] In one embodiment, based on the specified process steps, the total carbon emissions of all production resources in the production simulation model under the specified process steps within a preset time period are obtained. The specified process steps can be selected by the user, pre-set, or the carbon emissions corresponding to all relevant process steps of different production resources, such as semi-finished product experiments, atmospheric drying or precision release, are output. Assuming that the first device calculates a first carbon emission under the atmospheric drying process within a preset time period, and the second device calculates a second carbon emission under the atmospheric drying process within a preset time period, the first carbon emission and the second carbon emission are accumulated to obtain the total carbon emissions of the relevant equipment under the atmospheric drying process. Optionally, the carbon emissions corresponding to the specified order / emission source type / total workshop can also be output.

[0030] In one embodiment, in addition to displaying the total carbon emissions of production resources within a preset time period on a graphical user interface, key performance indicators (KPIs) of production within the corresponding preset time period can also be displayed, such as daily output, annual output, work-in-progress, production cycle time, equipment utilization, etc., thereby providing users with a richer statistical dimension. Users can intuitively understand the production KPI corresponding to the total carbon emissions of production resources within the preset time period on the graphical user interface. In this embodiment, the production digital twin model and the life cycle assessment model are integrated into a simulation platform for collaborative modeling and collaborative generation of simulation workflows. This is not only more convenient and faster in operation, but also helps users more effectively conduct horizontal comparisons of relevant data and adjust operational strategies in a timely manner.

As shown in FIG2 , electronic device 200 includes a processor 202 and a memory 201. Memory 201 stores instructions, wherein the instructions, when executed by processor 202, implement method 100 as described above.

[0032] Among them, at least one processor 202 may include a microprocessor, an application-specific integrated circuit (ASIC), a digital signal processor (DSP), a central processing unit (CPU), a graphics processing unit (GPU), a state machine, etc. Embodiments of computer-readable media include, but are not limited to, floppy disks, CD-ROMs, magnetic disks, memory chips, ROMs, RAMs, ASICs, configured processors, all-optical media, all tapes or other magnetic media, or any other medium from which a computer processor can read instructions.
