The data management platform includes: a transportation management sub-platform (TMS), a warehouse management sub-platform (WMS) and a carbon emission data collection sub-platform.

[0025] Among them, the transportation management sub-platform is mainly used to plan, execute and monitor the transportation activities of building materials, including route planning, transportation mode selection, transportation cost calculation, waybill management, transportation tracking and cargo delivery, etc. In this embodiment, the transportation management sub-platform is mainly used to manage and store the transportation data of all building materials in the material preparation stage, that is, the transportation mode, transportation distance and type of building materials, so as to track and calculate the carbon emissions in the material preparation stage later. The warehouse management sub-platform is used to manage the logistics and inventory management activities in the warehouse, including warehousing management, outbound management, inventory management, cargo management, order processing, picking and packaging, etc. In this embodiment, the warehouse management sub-platform is mainly used to manage and store the inbound and outbound data of all building materials, as well as the outbound data of all products.

[0026] The carbon emission data acquisition sub-platform usually has all the functions of SCADA (Supervisory Control And Data Acquisition) and MES (Manufacturing Execution System). SCADA and MES are two management systems widely used in the industrial field. SCADA is a software system used to monitor and control industrial processes. It collects data through field equipment and instrument sensors and transmits the data to the central control room, where operators monitor and manage the data. The SCADA system can monitor real-time data, record historical data, generate reports, provide alarms and event processing, etc., to help companies monitor and control the production process in real time.

[0028] Among them, energy consumption data and personnel data in the product production stage and waste treatment stage are important data sources, which are used to evaluate and monitor carbon emissions and energy consumption in the production process, and help factories to save energy, reduce emissions and manage resources. Among them, personnel data includes: the man-day data of labor required for product production during the execution of the production plan. Personnel data can help understand the carbon emissions and energy consumption generated by individuals at work, and formulate emission reduction and energy-saving strategies in a targeted manner. The energy consumption includes electricity metering, water metering and weighing metering related to production activities. Among them, electricity metering is the electricity consumption used in production activities, water metering is the use of water resources in production activities (including production, cleaning, cooling and other links), and weighing metering is the use of building materials, waste and waste recycling.

[0029] The carbon emission data from the start to the completion of the production plan includes the building material transportation data during the material preparation stage during the execution of the production plan by the smart construction factory, as well as the consumption data during the product production stage and the waste treatment stage.

[0030] A carbon emission calculation module, for obtaining the carbon emission amount during the material preparation stage of the smart construction factory during the execution of the production plan by the smart construction factory according to the building material transportation data during the material preparation stage of the production plan and a pre-set carbon factor library; According to the consumption data of the product production stage and the waste treatment stage during the execution of the production plan by the smart construction factory, and the pre-set carbon factor library, the carbon emissions of the product production stage and the waste treatment stage during the execution of the production plan by the smart construction factory are obtained respectively.

[0031] The carbon footprint tracking module is used to establish a carbon footprint tracking model corresponding to the production plan based on the carbon emissions from the start of the production plan to the completion of the production plan; the carbon footprint tracking model is used to track the carbon emissions of the smart construction factory at each stage from the start of the production plan to the completion of the production plan.

[0032] Furthermore, the building material transportation data includes the building material type, transportation method, transportation distance and transportation volume of each building material required to complete the production plan; The carbon emission calculation module obtains the carbon emission factor corresponding to the production of each building material through a pre-set carbon factor library according to the type of each building material required to complete the production plan in the production plan; According to the transportation mode of each building material required to complete the production plan, the carbon emission factor corresponding to each transportation mode is obtained through the pre-set carbon factor library; According to the building material transportation data during the material preparation stage during the execution of the production plan by the smart construction factory, the carbon emission factor corresponding to the production of each building material and the carbon emission factor corresponding to each transportation mode, and the preset formula 1, the carbon emissions during the material preparation stage during the execution of the production plan by the smart construction factory are obtained; the formula 1 is: ; Among them, C JC The carbon emissions during the material preparation stage during the execution of the production plan for the smart construction factory, M i is the transportation volume of the i-th building material, F 1-i is the carbon emission factor of the transportation method used for the i-th building material, F 2-i is the carbon emission factor corresponding to the production of the i-th building material, S i is the transportation distance of the i-th building material, i is the index of the building material, and n is the n building materials required to complete the production plan.

[0033] Furthermore, the carbon emission calculation module obtains the carbon emissions of the smart construction factory during the product production stage and the waste treatment stage according to the consumption data of the smart construction factory during the production plan and the pre-set carbon factor library. Taking the carbon emissions of the product production stage as an example, under normal circumstances, the carbon emission calculation module obtains the carbon emissions of the product production stage according to the pre-set formula 2; the formula 2 is: ; Among them, n z The man-days required to produce the zth product, f z is the average carbon emission factor of artificial z The length of time that the machinery and equipment required to produce the zth product is used, R z The energy carbon emission factor per unit time of the mechanical equipment required to produce the zth product, Q z The power consumption of small mechanical equipment required for the production of product z, EF z is the average carbon emission factor of the power grid in the area where the smart construction factory is located, m z The consumption of auxiliary materials and consumables required for the production of the zth product, F z is the carbon emission factor of auxiliary materials and consumables required for the production of product z, QSC It is the carbon emission during the production stage of the product.

[0034] Furthermore, tracking the carbon emissions of a factory also requires considering the non-production energy consumption during the factory operation. Therefore, the data collection module is also used to: obtain the operation data of the factory during operation, and according to the production plan of the smart construction factory and the pre-built data management platform, obtain the in-and-out data of all building materials required for the production plan and the out-and-out data of the products corresponding to the production plan; The operational data includes energy consumption generated by the factory's non-direct production activities.

[0035] The carbon emission calculation module is also used to obtain the carbon emissions of the operation of the smart construction factory from the start to the completion of the production plan based on the operating data of the smart construction factory during its operation, the inventory data of all building materials required for the production plan and the inventory data of the products corresponding to the production plan, as well as a pre-set carbon factor library.

[0036] The carbon emission tracking module needs to build a corresponding carbon footprint tracking model based on the smart construction factory's operation data during the material preparation stage, product production stage, waste treatment stage, and non-production stage during the execution of the production plan, so as to monitor and manage the carbon emissions of each stage in real time.

[0037] Furthermore, the data acquisition module is also used for: According to the production plan of the intelligent construction factory, the product outbound data corresponding to the production plan is obtained through the warehouse management sub-platform; the product outbound data includes the quantity of the product outbound; Then, the carbon footprint tracking module is also used to: According to the delivery data of the products corresponding to the production plan and the carbon emissions from the start to the completion of the production plan, the carbon emissions corresponding to each product in the production plan are obtained; According to the carbon emission and carbon footprint tracking model corresponding to each product in the production plan, a carbon footprint tracking sub-model corresponding to each product is obtained; The carbon footprint tracking sub-model is used to track the carbon emissions of any product in the production plan from the start of the production plan to the completion of the production plan.

[0038] Furthermore, the system also includes: a carbon emission optimization module and a carbon asset trading management platform.

[0039] Among them, the carbon emission optimization module is used to obtain the carbon emission difference used to optimize the production process based on the carbon footprint tracking model corresponding to any production plan and the pre-set benchmark carbon emission data model. The carbon emission difference is the difference between the actual carbon emissions of the smart construction factory and the benchmark carbon emissions.

[0040] The carbon asset trading management platform is used to obtain a carbon asset management strategy for guiding carbon asset trading and management at preset time intervals based on the carbon emissions of all production plans from the start of production plan execution to completion and the preset total amount of carbon assets within the preset time.

[0041] In another way, the data acquisition module can also obtain the Petri net model diagram corresponding to the production plan, that is, the carbon emission data from the start of the production plan to the completion of the production plan, based on the received production plan of the intelligent construction factory and the pre-built data management platform and the pre-set Petri net modeling technology; The Petri net model diagram includes material flows and energy flows in the material preparation stage, product production stage and waste treatment stage during the execution of the production plan by the intelligent construction factory.

[0042] Material flow and energy flow are important flow modes in the Petri net model, which respectively represent the transfer and transformation process of matter and energy in the production process. Material flow describes the flow trajectory and changes in the links of raw material (building material) transportation, processing, production, storage, and finished product delivery. Energy flow refers to the process of converting energy from one form to another in the production process.

[0043] The carbon monitoring and management system based on the intelligent construction factory provided in this embodiment addresses the differences in production tools, data sources, data types and data collection frequencies brought about by the transformation of prefabricated building production towards intelligence, digitization and automation. It solves the problem of how carbon emission calculations can adapt to the characteristics of intelligent construction data, solves the coordination problem between data management platforms, on-site instruments and carbon calculations, and expands its functions in carbon footprint tracking, carbon asset management, etc., and solves the problem of how to perform multi-dimensional conversion of carbon production data of prefabricated buildings.

[0044] Furthermore, this embodiment studies the carbon quantification method in the factory production stage according to the production characteristics of prefabricated buildings, realizes the improvement of the granularity of the calculation method, and innovatively obtains more accurate carbon emission data through real-time data capture of energy metering instruments in the production stage of prefabricated building factories. A carbon monitoring and management system is built based on the warehouse management sub-platform, transportation management sub-platform and carbon emission data collection sub-platform of the intelligent construction factory. Based on the complete carbon metering process and accurate analysis of the collected data, a low-carbon transformation strategy based on carbon metering data analysis of intelligent construction factories in the construction industry is proposed.

[0045] Example 3

[0046] This embodiment provides a carbon monitoring management method based on an intelligent construction factory, which covers carbon emission calculations at the organizational level and the product level, and in particular, at the product level, a detailed carbon footprint measurement method is proposed for the production stage of prefabricated building products. The method is implemented based on a pre-built carbon monitoring management system for an intelligent construction factory.

[0047] The system is as Figure 2 As shown, it integrates data collection, calculation, product carbon footprint tracking and evaluation functions, aiming to comprehensively and accurately monitor and manage the factory's carbon emissions.

[0048] Data collection: Energy metering instruments are deployed at key locations (such as instruments to monitor mixer power during concrete mixing) to monitor and record consumption data of various energy sources in real time. At the same time, a data interface is established between the system and the factory's warehouse management sub-platform and carbon emission data collection sub-platform to achieve automatic collection and seamless connection of carbon emission data, ensuring data accuracy and real-time performance. The carbon emission data collection sub-platform usually integrates all the functions of SCADA (Supervisory Control And Data Acquisition) and MES (Manufacturing Execution System), which are two management systems widely used in the industrial field.

[0049] Establishment of carbon factor library and calculation of carbon emissions: Utilize the collected energy consumption data and carbon emission data, combined with various carbon emission factors in the carbon factor library, to perform accurate carbon emission calculations. The carbon factor library is regularly updated and maintained to ensure the timeliness and scientificity of the data.

[0050] Product carbon footprint tracking and connection with other carbon functions: The system has a product carbon footprint tracking function, which can track and calculate the carbon emissions of prefabricated building components and modular building products during the production process. At the same time, the system can also be connected with other carbon-related functions, such as carbon emission rights trading and carbon asset management, to manage and optimize carbon emissions in an all-round way.

[0051] Carbon reduction improvement benefit evaluation and carbon reduction strategy proposal: The system continuously monitors and analyzes the factory's carbon emissions, can evaluate the actual effects of various carbon reduction measures, and intuitively demonstrate the effectiveness of carbon reduction measures by comparing with multiple dimensions such as the benchmark carbon emission data model. Based on the evaluation results of the carbon reduction improvement benefits, targeted carbon reduction strategies and suggestions are proposed for the factory.

[0052] Furthermore, the system deployment is carried out from three aspects: hardware, software and network: select appropriate servers, storage devices, network devices, etc. to ensure the stability and performance of the system and complete the hardware deployment; configure the operating system, database entry and other software and the basic software required for the carbon monitoring management platform; configure the network topology to ensure the stability and security of data transmission and complete the network configuration; debug the deployed system to ensure the normal operation of each component.

[0053] In order to ensure the integrity and accuracy of the data, an interface is built with the intelligent construction factory management platform (MOM manufacturing operation management sub-platform, WMS warehouse management sub-platform), and data is imported from other systems through the interface, such as material warehousing data, carbon emission data, energy consumption data, environmental monitoring data, etc. These data will serve as the basis for carbon measurement and carbon monitoring.

[0054] At the product level, the carbon footprint of products is accurately calculated and managed. By calculating the carbon emissions of individual products based on the total amount of production projects and considering the impact of carbon emissions in public areas during the same period (included in proportion to the production line area), the carbon footprint of each product can be accurately tracked. In addition, a carbon management system at the factory, production line, and product levels is established to monitor and manage carbon emissions in all aspects. By connecting with the carbon market, the product carbon footprint data is connected with carbon-related functions such as the carbon asset trading management platform to further improve the efficiency and effectiveness of carbon emission management.

[0055] The carbon asset trading management platform usually integrates the relevant functions of the carbon emission rights trading sub-platform and the carbon asset management sub-platform.

[0056] The method comprises: Carbon emissions at the organizational level focus on a comprehensive and accurate assessment of carbon emissions throughout the operation of the entire smart construction factory, including but not limited to carbon emissions generated by various energy sources consumed by the factory (electricity, heat, fuel, etc.), as well as carbon emissions generated by non-direct production activities such as internal factory transportation and office equipment.

[0057] In terms of carbon emissions at the product level, starting from the perspective of the industrial chain of prefabricated building components and modular building products, the Petri net modeling technology is used to conduct process analysis to clarify the material flow and energy flow of various PC components and modular units in factory production. By constructing a Petri net model diagram, the carbon emission sources of factory production activities are accurately identified, and the carbon emission calculation method is refined from the material preparation stage, component production stage and waste stage to achieve accurate tracking and calculation of product carbon footprint.

[0058] Specifically, we first start from the material preparation stage, and based on the acquisition of raw materials and the identified characteristics of carbon emission sources, we further refine the carbon emission calculation method from three aspects: raw material consumption, transportation distance, and transportation energy consumption.

[0059] Next, in the product production stage, according to the characteristics of the production process and the carbon emission sources in the factory, the carbon emissions of personnel, machinery (including water, electricity, gas, transportation, etc.), materials (auxiliary materials, material loss) and waste treatment are comprehensively considered to further refine the calculation of carbon emissions. The carbon emission calculation process is as follows: Figure 3 Finally, combining the carbon emission calculation results of these two stages, the carbon emissions and carbon footprint per unit area in the production stage of prefabricated building products were studied and calculated in depth.

[0060] Furthermore, an environmentally friendly production model is constructed. Specifically, based on the operating characteristics of intelligent manufacturing and the factory process, the transportation management sub-platform is used to intelligently manage the transportation of raw materials, and transportation carbon emissions are effectively controlled by optimizing routes and reducing transportation frequency. Next, the warehouse management sub-platform is introduced to achieve refined management of production material warehousing, improve inventory turnover, and reduce indirect carbon emissions caused by material retention.

[0061] Entering the production stage, we fully utilize the advantages of the carbon emission data collection sub-platform to conduct all-round and real-time monitoring of the production process, ensuring production efficiency and product quality while accurately capturing and recording production carbon emission data. In addition, the warehouse management sub-platform comprehensively covers key processes such as order processing, raw material warehousing, and product delivery. Its powerful data processing capabilities provide detailed and accurate data support for carbon emission calculations. At the same time, we also use IoT devices to monitor key carbon emission sources in the production process in real time, balance data accuracy and cost, accurately collect data at various locations, and build a scientific data model. We enter data from all stages of raw material production, transportation, production, and disposal into the model for in-depth analysis and precise carbon emission calculations, thereby comprehensively and accurately evaluating the carbon emissions of the entire production process. The above carbon emission-related data flows are as follows: Figure 4 shown.

[0062] In terms of carbon emission calculation, the three scopes of carbon emissions are clarified: direct emissions, indirect emissions and supply chain emissions. A carbon factor library containing basic carbon source factors such as the Chongqing University research group database, the University of Bath database, the Ecoinvent database and the GB / T51366-2019 building carbon emission calculation standard is established. Through merging and sorting, the basic and extended module carbon emission factors suitable for this project are formed to ensure the accuracy and scientificity of the calculation. In addition, the carbon data calculation module is developed in combination with the carbon emission factor library, and the data results will be further applied to carbon data analysis.

[0063] In order to intuitively display carbon emission data and evaluate the emission reduction effect, the platform displays carbon emission data by time (year, season, month), which is convenient for managers to understand the carbon emissions in different time periods. At the same time, the platform also displays carbon emission data by production project, so that managers can clearly see the carbon emissions and emission reduction effects of each production project. By comparing the carbon emissions per unit of output value and the carbon emissions of the same product (such as the comparison between the previous year and the next year), the factory can evaluate the implementation effect of various emission reduction measures and adjust and optimize the emission reduction strategy accordingly. In addition, the platform has also introduced digital twin technology to display data in a more intuitive way, further improving the data visualization effect.

[0064] Specifically, 3D modeling software is used to model the 3D models required for scene building of the intelligent construction factory, and model elements corresponding to all 3D models are obtained. According to the virtual coordinate information of the scene reference point and the real geographical location information corresponding to the target scene, the real coordinate information corresponding to the scene reference point is obtained; a coordinate conversion relationship is established according to the virtual coordinate information and the real coordinate information of the scene reference point; according to the coordinate conversion relationship and the real geographical location information of the target scene, the virtual coordinates of each 3D model are configured, and all 3D models are adjusted to corresponding positions; according to the pre-set repair tools, information diagnosis is performed on each 3D model, and the erroneous parts are corrected; the scene light source and the scene camera are configured to complete the building of the target scene.

[0065] After the construction is completed, it will be connected with the warehouse management sub-platform, transportation management sub-platform and carbon emission data collection sub-platform to receive real-time operation data generated by the factory during operation and carbon emission data generated during the production process, and based on the above data, generate carbon emissions generated by each process in each stage for display.

[0066] This embodiment studies the carbon quantification method in the factory production stage according to the production characteristics of prefabricated buildings, improves the granularity of the calculation method, and innovatively obtains more accurate carbon emission data through real-time data capture of energy metering instruments in the production stage of prefabricated building factories. A carbon monitoring and management system is built based on the warehouse management sub-platform, transportation management sub-platform and carbon emission data collection sub-platform of the intelligent construction factory. Based on the complete carbon metering process and accurate analysis of the collected data, a low-carbon transformation strategy based on carbon metering data analysis of intelligent construction factories in the construction industry is proposed.
