Hereinafter, an embodiment will be described in detail with reference to the accompanying drawings.

1 is a diagram illustrating an example of a reliable carbon emission management method in a product production design stage according to an embodiment of the present invention. The carbon emission management method according to the present embodiment may be performed by a carbon emission management system. A carbon emission management system is a system of a company that wants to manage carbon emissions and may be implemented by at least one computer device. As will be described later, the carbon emission management system may include a supply chain management (SCM) system and an enterprise resource planning (ERP) system of the corresponding company. Management) system may be further included.

In step 110, the carbon emission management system may register design data on a computer aided design (CAD) system for production. When a company's engineer proceeds with design work for product production, the design data delivered through the CAD desktop used within the company can be registered in the carbon emission management system. In this process, basic information (type, quantity, etc.) of material parts required for product production may be registered.

In step 120, the carbon emission management system may analyze production factor data based on the registered design data. For example, the carbon emission management system may derive production factor data required for product production based on design data registered through a control unit connected to a company's ERP system or a separate CAD (Computer Aided Design) system.

In step 130, the carbon emission management system may generate a bill of distribution (BOD) for parts supply based on design data and production factor data. At this time, the carbon emission management system may generate a BOD for supplying parts required for production based on basic information on the material part registered as design data and analyzed production factor data.

In step 140, the carbon emission management system may register the generated BOD on the blockchain for carbon disclosure. The generated BOD can be registered on the SCM system after inspection by the manager. At this time, instead of directly transferring BOD-related information from the ERP system to the SCM system for carbon emission management, the ERP system creates a smart contract for carbon emission management. After updating (registering) BOD-related information on the blockchain for carbon disclosure, it can be registered on the SCM system. Through this, parts procurement information related to product production can be managed using blockchain, and carbon information of material parts made in the production process can be managed in an unmodifiable form.

In step 150, the carbon emission management system may generate a bill of material (BOM) for production management based on the design data. In the case of the generated BOM, it may be used to track carbon emission-related information of a specific material part in association with corresponding BOD information.

In step 160, the carbon emission management system may register the generated BOM on the blockchain for carbon disclosure. BOM for production management can be registered on the ERP system, and in this process, BOM-related information is recorded (registered) on the blockchain for carbon disclosure using smart contracts, and then BOM information is updated (registered) on the ERP system. ), it is possible to prove reliability.

2 is a diagram showing an example of the configuration of a blockchain network for carbon disclosure according to an embodiment of the present invention. The carbon emission management system 200 may correspond to the carbon emission management system described with reference to FIG. 1, and may include the SCM 210, the ERP 220, the MES 230, and the CRM 240. Here, the SCM (210), ERP (220), MES (230), and CRM (240) can correspond to the SCM system, ERP system, MES, and CRM system described with reference to FIG. 1, respectively, and block chains for carbon disclosure, respectively. (250) may include a smart contract for recording information related to carbon emission.

The carbon emission management system 200 and/or the block chain 250 may be linked with a supply chain operator (Supplier Company & Network, 261) of the company. For example, in the case of companies linked to the company's SCM 210, information can be processed based on smart contracts to track carbon emissions. At this time, the carbon emission-related information presented by the supply chain operator 261 may be recorded on the blockchain 250, and if there is a problem with the carbon emission-related information in the future, responsibility based on the information recorded on the blockchain 250 can confirm the presence of On the other hand, in the case of the supply chain operator 261, it is possible to expand opportunities to be used in major supply chains in the future by explicitly guiding carbon emission-related information for its parts through the blockchain 250. To this end, the supply chain operator 261 must be able to explicitly provide information related to carbon emissions of its products. In particular, when linked with the Carbon Market (262) described later, since more objective evidence for carbon emission-related information becomes possible, it is possible to secure trust in the supply chain.

In addition, the carbon emission management system 200 and/or the blockchain 250 may be linked to the carbon market 262 for carbon emission-related transactions. As already described, the carbon market 262 may provide more objective evidence of carbon emission related information provided by the supply chain operator 261 . In addition, if a problem arises in the carbon emission-related information presented by the supply chain operator 261 in the future, sanctions from the Carbon Market 262 may be applied to the supply chain operator 261 .

In addition, the carbon emission management system 200 and/or the blockchain 250 may be linked with the company information disclosure system 263. The company information disclosure system 263 may provide reliability of information based on energy-related contract information of a company based on carbon emission-related information recorded in the block chain 250 . Companies should be able to utilize production-related energy use information or investment information that can be publicly announced to prove carbon emissions. However, production-related energy consumption information or investment information has a one-time nature, and the scale can be applied in connection with the contract period, so it must be managed transparently and reliably. Accordingly, a company may register production-related energy use information or investment information in the blockchain 250 in association with the company information disclosure system 263 and manage and use it in the form of a Non-Fungible Token (NFT).

In addition, the carbon emission management system 200 and/or the blockchain 250 may be linked with the logistics management system 264. In this case, carbon emission-related information in the product transportation process may be additionally linked and recorded in the blockchain 250.

The carbon emission management system 200 and/or the blockchain 250 may be linked to a consumer 265. The consumer 265 may inquire and verify carbon emission-related information in the block chain 250.

In addition, companies need to disclose some of their supply chain information (eg, key information related to production) in order to track carbon emission-related information. At this time, the company's carbon emission management system 200 manages carbon emission-related information of raw materials or parts used for production through the SCM 210, and transmits such carbon emission-related information through the smart contract of the SCM 210. It can be provided to the blockchain 250 for carbon disclosure.

In addition, companies need to provide carbon emission-related information based on information made in the manufacturing process. In particular, information on parts or materials made in the manufacturing process, related input manpower, and energy sources required for the production process, such as electricity or gas, must be managed so that they can be included in carbon emission-related information. This is closely related to the operation time of product production machines, and the company's carbon emission management system (200) is based on serial numbers such as lot (LOT) in BOM units through ERP (220) and MES (230). It is possible to trace information related to carbon emissions generated in the process of production. In addition, information on equity investment, PPA (Power Purchase Agreement) contract, REC (Renewable Energy Certificate) purchase, etc., which greatly affect carbon emission-related information as a one-time contract, can be managed transparently, and the carbon emission management system (200) may provide a management function for a separate transaction through the ERP (220) and the MES (230).

In addition, the CRM 240 may basically provide a function for customers to check transparent carbon emission-related information on manufactured products. The CRM 240 may provide carbon emission-related information by adding carbon footprint information in a logistics process when a manufactured product is delivered to a customer.

As described above, according to embodiments of the present invention, a carbon emission management method and system using a block chain can be provided.

3 is a diagram showing an example of a configuration relationship between a smart grid and a blockchain network according to an embodiment of the present invention. The carbon public blockchain 310 may be connected to an energy provider domain 330 , a grid domain 340 , and a customer domain 350 through a communication network 320 . The energy provider domain 330 may include energy markets, energy operators, energy supply service providers, and the like. A grid domain may include a bulk generation, a transmission system, a distribution system, and the like. In addition, customer domain 350 may include smart appliances, electric vehicles, local networks, and the like.

If most of the energy sources consumed in a company's production environment are based on electricity, certification linked to a smart grid network can provide evidence of the energy requirements required to produce products. By providing proof of actual energy consumption using suppliers on the smart grid or certified products in the energy market, companies can certify their energy consumption. In particular, considering the current energy production situation in which companies use renewable energy and the amount of use is inevitably variable, a method that can quantitatively record this is essential.

The energy supplier of the energy supplier domain 330 should be able to provide its carbon emission-related information on the carbon disclosure block chain 310 according to the customer's request. In particular, when energy sources change rapidly, such as in the energy market, carbon emission-related information must be provided transparently. Therefore, the corresponding energy suppliers may provide carbon emission-related information for supplied energy to the carbon disclosure block chain 310 by using a smart contract under consultation with the customer.

Customers of the consumer domain 350 may receive energy through the energy market of the energy provider domain 330 or energy through a dedicated energy operator. Customers can disclose information about their electric energy utilization in advance and, based on this, negotiate carbon emissions with related businesses. Afterwards, the information of the smart meter (360) and energy provider can be registered and updated on the carbon public blockchain (310).

4 is a flowchart illustrating an example of a carbon emission management method in a smart grid-centered power usage environment according to an embodiment of the present invention. The carbon emission management method according to this embodiment may be performed by a carbon emission management system (eg, the carbon emission management system 200).

In step 410, the carbon emission management system may select carbon management product information based on the company's delivery information. At this time, the carbon emission management system may select carbon management product information based on information according to the company's delivery requirements.

In step 420, the carbon emission management system may create a BOM by establishing manufacturing and production processes. At this time, a corresponding manufacturing and production process based on delivery information may be established. In general, after generating the BOM and BOD information, it can be determined whether the production process is established based on the data at the time of MES 230 connection.

In step 430, the carbon emission management system may request submission of carbon emission-related information to a supplier based on BOD information connected in manufacturing and production processes. At this time, the carbon emission management system may request carbon emission-related information from suppliers registered on the SCM 210 based on the BOD information. The supplier may submit carbon emission-related information based on a contract or may provide carbon emission-related information by being connected to a peer (node) of the carbon disclosure blockchain 310 through a smart contract.

In step 440, the carbon emission management system may check a related energy transaction network to collect energy consumption information of the corresponding company. The carbon emission management system can identify an energy trading network that can reliably provide energy consumption information in order to collect energy consumption information of the company. If necessary, a smart meter (360) can be introduced into the production process to build a reliable energy consumption information collection environment. Consumption information can be collected.

In step 450, the carbon emission management system may connect a smart contract to check information on the related energy trading network. For example, when using a smart grid or an energy market, the carbon emission management system may acquire configuration information of consumed energy using a smart contract connected through linkage with corresponding companies. In particular, the energy market can provide accurate information on energy production sources.

In step 460, the carbon emission management system may check the carbon emission amount of the product. At this time, the carbon emission management system may check the carbon emission based on product lot (LOT) based on node information of the connected network (energy trading network).

Meanwhile, the carbon emission management system according to an embodiment may be utilized in connection with other information related to decarbonization. In order to decarbonise according to the company's product production, it is possible to connect the efforts of various related companies. However, in the case of information for the linkage, carbon emission-related information in an explicit, non-redundant form can be managed transparently.

As a method of energy conversion based on renewable energy or carbon trading other than direct production, equity investment, PPA contract, REC purchase, green premium rate system, linkage with emission trading system, etc. can be considered.

In the case of such one-time information of the company, after registering the information in the form of NFT on the system, the information can be used for transactions. In the case of one-time information, it can have a great impact on overall production, but it can be used transparently because there is an issue that is recycled. In addition, companies can provide a function to inquire at any time through the carbon emission management system.

In this way, according to embodiments of the present invention, it is possible to provide a carbon emission management method and system in conjunction with a smart grid in a production process.

5 is a block diagram illustrating an example of a computer device according to one embodiment of the present invention. The carbon emission management system described above may be implemented by at least one computer device (Computer device, 100). As shown in FIG. 7, the computer device 500 may include a memory 510, a processor 520, a communication interface 530, and an I/O interface 540. can The memory 510 is a computer-readable recording medium and may include a random access memory (RAM), a read only memory (ROM), and a permanent mass storage device such as a disk drive. Here, a non-perishable mass storage device such as a ROM and a disk drive may be included in the computer device 500 as a separate permanent storage device separate from the memory 510 . Also, an operating system and at least one program code may be stored in the memory 510 . These software components may be loaded into the memory 510 from a computer-readable recording medium separate from the memory 510 . The separate computer-readable recording medium may include a computer-readable recording medium such as a floppy drive, a disk, a tape, a DVD/CD-ROM drive, and a memory card. In another embodiment, software components may be loaded into the memory 510 through the communication interface 530 rather than a computer-readable recording medium. For example, software components may be loaded into the memory 510 of the computer device 500 based on a computer program installed by files received through a network 560 .

The processor 520 may be configured to process commands of a computer program by performing basic arithmetic, logic, and input/output operations. Instructions may be provided to processor 520 by memory 510 or communication interface 530 . For example, processor 520 may be configured to execute received instructions according to program codes stored in a recording device such as memory 510 .

The communication interface 530 may provide a function for the computer device 500 to communicate with other devices through the network 560 . For example, a request, command, data, file, etc. generated according to a program code stored in a recording device such as the memory 510 by the processor 520 of the computer device 500 is transmitted to the network ( 560) to other devices. Conversely, signals, commands, data, files, etc. from other devices may be received by computer device 500 via communication interface 530 of computer device 500 via network 560 . Signals, commands, data, etc. received through the communication interface 530 may be transferred to the processor 520 or the memory 510, and files may be stored as storage media that the computer device 500 may further include (described above). permanent storage).

The input/output interface 540 may be a means for interface with the input/output device (I/O device, 550). For example, the input device may include a device such as a microphone, keyboard, or mouse, and the output device may include a device such as a display or speaker. As another example, the input/output interface 540 may be a means for interface with a device in which functions for input and output are integrated into one, such as a touch screen. The input/output device 550 and the computer device 500 may be configured as one device.

Also, in other embodiments, computer device 500 may include fewer or more elements than those of FIG. 1 . However, there is no need to clearly show most of the prior art components. For example, the computer device 500 may be implemented to include at least some of the aforementioned input/output devices 550 or may further include other components such as a transceiver and a database.

6 is a diagram showing an example of a production and consumption flow of a product according to an embodiment of the present invention. In the case of manufactured goods, production and utilization are carried out through various stages, and in this process, the final product in a specific process is used as a part in another process, resulting in a complex life cycle. When data is acquired based on smart factories in the manufacturing production stage, the information is continuously linked to production companies or logistics companies, so that information on unique manufacturing products is cumulatively generated, and whenever a product changes hands, the corresponding Information is passed on or discarded.

An add-on module (610) is a function and device that can be included in the entire process for production of a product, and can play a role in acquiring product information. In the embodiment of FIG. 6 , an example in which the add-on module 610 is coupled to points that can be linked with a block chain in the process of producing a product is shown. For example, when production is performed through a device on a production line, information related to the operating state of the production equipment and the production quality of the product (inspection information, etc.) corresponds to this.

Quality verification of products in the production stage using AI is becoming more active, and information related to the quality of products in the production stage is continuously collected and used in the form of big data for various reasons, such as production chain management and quality control of suppliers. In addition, as the complexity of the supply chain increases, manufactured goods (products) are actually used through various stages and physical movement, and thus external factors related to quality may occur during transportation and movement. Therefore, the producer should provide a quality verification method in the form of assurance to the supplier for his/her product, and through this, should be able to avoid or respond appropriately when a quality problem occurs.

7 is a diagram showing an example of a blockchain interworking module according to an embodiment of the present invention. In this embodiment, a block chain is configured so that stake holders can mutually trust the data collected in the manufacturing production stage, and the reliability of data collected by utilizing smart contracts based on each contract It shows an example of providing a block chain interworking module 700 so as to secure. The blockchain interworking module 700 can be connected to a device or module that generates various data in a manufacturing environment, and transmits the collected data to a blockchain network through appropriate processing. At this time, data preprocessing can be performed based on smart contracts as needed, and authentication methods or encryption methods specified by the supply chain can be supported as needed.

The blockchain interlocking module 700 according to this embodiment may have a separate hardware configuration so as to be effectively applicable to the existing manufacturing production environment, and may have a connection at the equipment level as well as a machine control facility and can work in tandem. At this time, interfaces of devices that can be connected include HMI (Human machine interaction), PLC (Programmable Logic Controller), RFID (radio frequency identification), barcode, signal through relay, SCADA (Supervisory Control And Data Acquisition), etc. A variety of interfaces can be supported.

In addition, the blockchain interworking module 700 may be connected to software used in a manufacturing production environment. The blockchain interworking module 700 can mount its own smart contract according to the hardware characteristics of the system. In this case, the blockchain interworking module 700 can be used to verify the authenticity and reliability of collected data by executing a smart contract according to separately defined rules at the time of data collection. For example, if a specific product manufactured by company A is used as a major component in company B's product, company B requests a blockchain-based SCM (Supply Chain Management) proposal from company A at the time of ordering, and the main details include: Reliability can be demanded for monitoring values of specific quality-related data from production control facilities. At this time, Company A creates a smart contract that satisfies the characteristics required by Company B, mounts it on the blockchain linking module 700, and links it to manufacturing production management facilities, so that B can trust the data at the time of production. It can be collected in the form and stored on the blockchain.

9 is a flowchart illustrating an example of a method of linking manufacturing production data to a block chain according to an embodiment of the present invention. The linkage method according to this embodiment may be performed by the block chain linkage module 700 described above. At least some of the steps 910 to 970 included in the association method may be performed by a human, and in this case, a process performed by a human may be omitted from the association method according to the present embodiment.

In step 910, the block chain interworking module 700 may check the supply contract for the product. When a producer concludes a supply contract for a product with a supplier, the block chain linkage module 700 may receive information on the concluded supply contract.

In step 920, the block chain interworking module 700 may check the quality requirements of the supplier. For example, if there is a request for separate production and manufacturing data for trust management of blockchain-based SCM or a separate blockchain network or product quality from the supplier, the information on this is interlocked with the blockchain according to a pre-set frame as a quality requirement. input to module 700. In addition, quality requirements may include collection requirements such as smart contract application or encryption application.

In step 930, the block chain interlocking module 700 may select a target device for installing the add-on module among production facilities.

The installation targets are 1) a point to check the ratio of major raw materials, 2) a point to create key quality-related sensing data during key production procedures, 3) a point to check whether a device is malfunctioning, and 4) a unique serial number of the product. It can be a point to do.

Depending on the embodiment, the preceding steps 910 to 930 may be performed by a person, and in this case, the steps 910 to 930 may be omitted.

In step 940, the block chain interworking module 700 may establish a network interface with the add-on module 610 installed in the manufacturing production facility. After the add-on module 610 is mounted in major manufacturing production facilities related to quality, a network interface for data linkage between the block-chain interworking module 700 and the add-on module 610 may be set. At this time, the data of the manufacturing production facility may be connected to the next network device in the form of being relayed through an add-on module.

In step 960, the blockchain interworking module 700 may pre-process the collected data by applying a smart contract application or a collection requirement of encryption application. For example, the blockchain interworking module 700 may apply collection requirements, such as application of smart contracts or encryption previously described in step 920, to the data collected through the add-on module. Therefore, the collected data can be pre-processed according to the requirements of the supplier.

In step 970, the blockchain interworking module 700 may link the pre-processed data with a blockchain system and/or a company information system. As an example, the blockchain interworking module 700 may store preprocessed data collected through an add-on module in a blockchain system and/or a company information system. The stored data can be provided to users, such as suppliers, and can provide reliability for various data in the manufacturing environment.

10 is a diagram illustrating an example of linking and utilizing a supply chain using a block chain according to an embodiment of the present invention. The supply chain-linked blockchain network 1010 according to this embodiment can be used for automatic payment or supplier matching through data-based quality trust. As an example, the supply chain-linked blockchain network 1010 may provide information related to the quality at the time of production of the product to a supplier through a blockchain connection with a manufacturing production facility (eg, a corporate production management system 1020). . In addition, information such as quality requirements for each supplier may be registered in the supplier pool 1030 through the supply chain-linked blockchain network 1010, and negotiations may be conducted on products based on quality or price. Depending on the embodiment, the supply chain linkage blockchain network 1010 may include the above-described blockchain linkage module 700.

When it is confirmed that normal quality conditions are satisfied through the supply chain-linked blockchain network 1010, it is possible to automate payment by using the smart contract provided by the supplier based on the information. In addition, even if a product is partially damaged or of poor quality, the product can be excluded from payment or a discount rate can be applied using the smart contract provided by the supplier.

If the quality requirements required by a specific supplier are not met, but a business network requiring a different quality is connected, the supply chain of the product can be automatically changed. To this end, when producing a product in the BOM (Bill Of Material) unit, if the quality requirements for the quality of the product cannot be satisfied, a smart contract that changes the BOD (Bill Of Distribution) to the producer that requires differential quality is connected. can

In step 1130, the supply chain-linked blockchain network 1010 may match quality requirements for each supplier on the supplier pool. The supply chain-linked blockchain network 1010 may receive quality requirements from each of a plurality of suppliers and disclose the quality requirements of the suppliers to blockchain network participants based on supply chain superiority. The supply chain-linked blockchain network 1010 may register the received quality requirements for each supplier on the supplier pool. At this time, the supply chain-linked blockchain network 1010 may perform a matching operation between the producer and the supplier by comparing the quality information of the product and the quality requirements for each supplier using a smart contract. Here, the product quality information may be product quality information registered in the supply chain-linked blockchain network 1010, and may be data preprocessed in step 960 of FIG. 9 and stored in the blockchain system.

At this time, the priority of the connection may be determined according to various forms, such as based on the delivery price or, in the case of a Point of Sales (PoS)-based network, based on pre-order priority distribution.

In step 1140, the supply chain-linked blockchain network 1010 may negotiate discount rate information according to matching. For example, the supply chain-linked blockchain network 1010 may process negotiations between the supplier and the producer by connecting the matched supplier and the producer. Depending on the embodiment, step 1140 may be performed by a person, in which case step 1140 may be omitted.

In step 1150, the supply chain-linked blockchain network 1010 may deliver matched supplier information on the manufacturing company's production management system. The manufacturing company (producer) may receive information on the supplier for the successful bid product through the smart contract of the supply chain-linked blockchain network 1010.

In step 1160, the supply chain linkage blockchain network 1010 may update the received BOD information on the corresponding product (product) of the manufacturing company. The producer may update the delivery information of the corresponding product and record it on the BOD or ERP, etc. so that the supply chain linked blockchain network 1010 can grasp it.

In step 1170, the supply chain linkage blockchain network 1010 may update product delivery information. For example, when a product manufactured by a manufacturing company is normally delivered to a matched supplier, the supplier can update whether or not the delivery is normal to the supply chain linkage blockchain network 1010, and the supply chain linkage blockchain network 1010 Information on normal delivery can be registered.

In step 1180, the supply chain-linked blockchain network 1010 may settle product costs. For example, as normal delivery is confirmed, the supply chain-linked blockchain network 1010 may process the supplier to settle the cost to the manufacturing company (producer) using a smart contract.

Each of the above-described add-on module 610, blockchain interworking module 700, and supply chain linkage blockchain network 1010 may be implemented by at least one computer device 500.
