Description
Technical Field
The invention relates to the field of full-life-cycle evaluation data processing, in particular to a block chain-based full-life-cycle evaluation data system and a control method thereof.
Background
The method for reducing carbon emission in the chemical industry comprises the following steps: energy evaluation, cost and price control, and medium and downstream industries: recycling and biological fuel. A single-factor method is adopted to evaluate the environmental impact of the product in the early period, and experts propose a comprehensive evaluation method, namely Life Cycle evaluation, in the early 90 s of the 20 th century.
The LCA refers to the compilation and evaluation of input, output and potential environmental impact in the life cycle of a product system, and specifically comprises the following four steps which are interrelated and repeated continuously: determination of purpose and scope, inventory analysis, impact evaluation and result interpretation. Life cycle assessment is a technique and method for assessing the environmental impact of a product throughout its life cycle, i.e., from the acquisition of raw materials, the production of the product, through disposal of the product after use. As a new environmental management tool and a preventive environmental protection means, life cycle evaluation is mainly applied to a method of evaluating environmental load caused by a product, a process and production activities by determining and quantitatively studying energy and substance utilization and environmental emission of wastes, evaluating the influence of energy material utilization and waste emission, and evaluating environmental improvement.
LCA has become a popular evaluation method all over the world, and has both international standards and converted national standards. At present, the evaluation and calculation of domestic LCA depend on software and databases at home and abroad, and the main data sources include software databases, documents, enterprise self databases and the like. Due to the lack of system management, data from multiple sources has a great problem in data security and interactivity, and data from different sources is easy to have problems of difficult circulation, intellectual property dispute, disclosure and the like. In addition, the database of LCAs has significant shortcomings in transparency and security.
The block chain is a novel scientific technology, and is a safety system with the characteristics of decentralization, distribution, transparence, traceability, tamper resistance and the like. Blockchains can be divided into public, private, and allied chains. The public chain represents applications including Bitcoin (Bitcoin) and Ethereum (Ethereum), etc., the private chain represents applications as multi-chain (Multichain), and the alliance chain represents application platforms including hyper-account (hyper-hedger Fabric), ant open alliance chain, etc. In the development of many years, the blockchain technology is expanded to the outside of the financial industry from the application of digital currency to financial settlement, and covers aspects of human social life, including various fields such as agriculture, food, justice, medical treatment, logistics, government affairs, industry (automobiles, aviation and electronic equipment), military, finance, multimedia and the like. However, there is no solution in the prior art to combine the blockchain technique with LCA.
There exists a need in the art for a lightweight analysis of the carbon footprint during transportation of basic food supply chain items in private clusters. The scheme aims to integrate the Internet of things equipment on the truck and collect information such as carbon footprint, mileage, products and the like. The system has three types of nodes: a leader node, a normal node, and a candidate node. The leader node is responsible for packing and delivering the blocks in a broadcast form to other common nodes to blame the received blocks. The candidate node is responsible for initiating election notifications. Each node contains a random timer. The candidate node broadcasts a state change notification requesting approval to become the leader. The technical scheme is based on the combination of the Internet of things such as RFID and the block chain technology, and the application field is the food field. However, the carbon footprint in the food field is limited to only the transportation supply chain segment, and involves less in other segments. In the industrial field, the carbon footprint is spread almost throughout the links. Compared with the carbon emission households in the chemical industry and the like, the carbon footprint analysis of the scheme is general, the application is narrow, the real carbon footprint analysis is difficult to realize, the cost is high, the data throughput is high, the operation speed is slow, and the data transparency and safety are poor.
Therefore, a technical solution for combining the full life cycle evaluation and the blockchain technique is needed to solve the above problems.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example 1
The embodiment provides a block chain-based full-life-cycle evaluation data system, which combines a block chain technology and full-life-cycle evaluation to realize public, transparent and safe management of full-life-cycle data. The full life cycle evaluation data system is shown in the attached figure 1 of the specification, and the specific scheme is as follows:
the full life cycle evaluation data system based on the block chain comprises a data module 1, a network module 2 and a terminal module 3. The data module 1 comprises a full lifecycle assessment block chain 14, an application server 13, at least one management server 11 and a plurality of database servers 12. The terminal module 3 comprises a management system terminal for evaluating data with respect to the entire life cycle, which management system terminal establishes a communication connection with the application server 13. The network module 2 establishes communication connection with the management system terminal through the internet. The network module 2 performs data interaction of the full-life-cycle evaluation data with a preset full-life-cycle evaluation block chain 14, and is used for updating and storing the full-life-cycle evaluation data.
Specifically, the management server 11 employs an intelligent contract technique to constrain the database server 12 and the application server 13. A Smart contract (Smart contract) is a computer protocol intended to propagate, verify or execute contracts in an informational manner. Smart contracts allow for trusted transactions to be conducted without third parties, which transactions are traceable and irreversible with the goal of providing a secure method over traditional contracts and reducing other transaction costs associated with the contracts. The management server 11 is mainly used for managing the database server 12 and the application server 13, improving the safety of the full life cycle evaluation data system and reducing the transaction cost.
The database server 12 is connected to a preset full life cycle evaluation database and a preset application device, respectively. The preset application devices include various devices for providing related data, and the application devices are different in different fields. And in each link of the full life cycle, data are stored through the full life cycle evaluation database. The full-life-cycle evaluation database stores therein full-life-cycle evaluation data, and preferably, the database server 12 is connected to a plurality of full-life-cycle evaluation databases. In this embodiment, the database server 12 adopts asymmetric encryption of the neural network chaotic attractor, and has a high encryption degree and high data security.
Unlike symmetric encryption algorithms, asymmetric encryption algorithms require two keys: public key (publickey) and private key (privatekey). The public key and the private key are a pair, if the public key is used for encrypting data, only the corresponding private key can be used for decrypting the data; if the data is encrypted with a private key, it can only be decrypted with the corresponding public key. The asymmetric encryption has the characteristics of simple key distribution, small key storage amount and high confidentiality requirement.
The application server 13 establishes a data connection with each database server 12 regarding the full-life-cycle evaluation data, respectively, and stores a switching condition for switching the respective database server 12. Each application server 13 establishes data connection with each full-life-cycle evaluation database server 12, and if there are n application servers 13 and m database servers 12, each application server 13 establishes data connection with m database servers 12, so that there are n × m data connection relationships. Accordingly, each application server 13 stores a respective switching condition for switching the database server 12. When finding that the switching condition a is satisfied, the certain application server 13 switches to the database server 12a corresponding to the condition a; when an application server 13 finds that the switching condition B is satisfied, the application server is switched to the database server 12B corresponding to the condition B.
Preferably, the application server 13 employs a POS mechanism to increase the processing speed of the data. The POS mechanism selects the application category based on the "equity" owned by the user, e.g., if the user owns 10% shares, then 10% of the transactions are applied. The POS mechanism can significantly improve data processing efficiency.
In the data module 1, each supply chain link involved in the whole life cycle can form a traceability system by embedding an RFID label, a GPS Internet of things device and the like, and collects, records and transmits product and logistics related information data in real time. The traceability system is a production control system which can track products forward, backward or not, and is applicable to various types of processes and production control systems. Each supply chain link can upload information data to a full life cycle evaluation database of the intermediate node, and can also perform interactive sharing and supervision and verification of the databases in the alliance. Since the block chain technology uses a combination of public and federation chains, there are databases within a federation. The full life cycle database of the intermediate node may upload the data hash and the product ID to the head blockchain database system, or may invoke the data hash and the product ID from the head blockchain database system.
The network module 2 can communicate with the full-life-cycle evaluation data management system terminal through the internet, and update and store the full-life-cycle evaluation data. The user can send a corresponding operation request through the management system terminal, and the network module 2 receives the operation request sent by the management system terminal and operates the internally stored full-life-cycle evaluation data according to the operation request or sends the corresponding full-life-cycle evaluation data to the management system terminal. In addition, the network module 2 also provides the record data for the use condition of each user at the management system terminal. Illustratively, for the data read by the RFID reader or the usage of each user at the management system terminal, the network module 2 may record and store the relevant recorded data for subsequent viewing.
In the present embodiment, the network module 2 provides a data interaction interface for the full-life-cycle evaluation data to implement data interaction with the full-life-cycle evaluation block chain 14 at regular time, and perform coverage update on the stored full-life-cycle evaluation data. The network module 2 is connected to the full life cycle evaluation block chain 14, and can acquire full life cycle evaluation data from the block chain and transmit the full life cycle evaluation data to the block chain.
The terminal module 3 includes a management system terminal based on the full life cycle evaluation data, and the management system terminal is connected to the application server 13. The management system terminal is provided with a special authentication system, so that one-stop service is provided for evaluation and authentication of the whole life cycle, and the accuracy and the fairness of the data module 1 are ensured. Man-machine interaction is realized through a management system terminal, and different rights are given to different users according to a preset rights and interests distribution rule. For example, a general user (business or school) may register account information, send operation requests, and view relevant full life cycle assessment data at a management system terminal. A supervisor, such as a third party organization and other special users can perform data authentication and feedback work through the intervention of a management system terminal.
Wherein, the full life cycle evaluation block chain 14 adopts a combination form of a public chain and a alliance chain. The public chain refers to a chain of consensus blocks where anyone can read the data, send the transaction, and the transaction can be validated. The public chain has the highest decentralization degree and is characterized in that: all nodes are shared, fully open, any person or organization can join anonymously, data on the chain is globally visible, and the method is generally used as a basic service. But the public chain has large data throughput and slow transaction speed. The alliance chain is between a public chain and a private chain, and can realize that each node on a partial decentralized chain usually has a corresponding entity mechanism or organization; participants jointly maintain blockchain operation by authorizing to join the network and forming a benefit-related alliance. Characteristics of the federation chain: the alliance of the private chain is open to a specific organization, information authorization on the chain is visible, a strong privacy protection mechanism is provided, business is emphasized, and the performance reaches a practical stage. The data throughput of the alliance chain is moderate, and the transaction speed is high. The full life cycle evaluation block chain 14 in this embodiment combines the public chain and the alliance chain, which not only retains the openness of the public chain, but also considers the security of the alliance chain. On the basis of realizing the publicization, transparentization and safety of the full life cycle evaluation data system, the running speed of the data system is ensured.
Specifically, the full life cycle assessment block chain 14 is a tree structure and includes a root node, an intermediate node, and a head node, and a block chain structure diagram is shown in fig. 2 of the specification. The root node comprises an enterprise database of each supply chain link in the full lifecycle; the intermediate nodes comprise intermediate node databases, and each root node has a corresponding relation with the intermediate node databases; the head node comprises a head block chain database which is a public chain of a decentralized chain as a whole and is connected with the intermediate node database. All nodes of the life cycle evaluation connected with the data system provided by the embodiment form a super-scale database neural network structure, and form an important cornerstone of the full life cycle evaluation. The enterprise database, the intermediate-node database, and the head blockchain database are all essentially full lifecycle databases.
A alliance neural network database system is formed among the root nodes, and high-speed interaction and backup of data can be performed under a PBFT or DPOS mechanism. Because the block chain adopts a mode of combining the alliance chain and the public chain, the enterprise database on the root node forms a neural network database system similar to the same alliance. The databases of the enterprises involved in each supply chain link form the underlying most basic database. The data of each flow in the whole life cycle can be accurately tracked by inquiring the enterprise database on the root node, and the openness and transparency of the data in the whole life cycle evaluation data system are ensured.
Each root node corresponds to a corresponding intermediate node database, each intermediate node database forms a closed-loop structure, and the whole root node and the intermediate nodes can perform transverse and longitudinal data interaction and tracing. When a problem occurs in a certain supply chain node, transverse and longitudinal data tracing can be realized by tracking the corresponding root node and the middle node. In the embodiment, each supply chain link forms a traceability system by embedding other external equipment so as to collect, record and transmit relevant information data of products and logistics in real time; each supply chain link uploads the related information data to the intermediate node database or carries out interactive sharing and supervision verification with a preset enterprise database. In practical application, the preset enterprise database is mainly an enterprise database with a federation relationship, and partial data sharing can be realized among enterprise databases in the same federation. The flow schematic diagram is shown in fig. 3 of the specification, and the databases corresponding to the nodes are databases i + n respectively, and are used for recording data in the processes of raw material, production, use, abandonment, recovery and regeneration.
Wherein, the head block chain database is connected with the intermediate node database. The intermediate node database may upload the data hash and the product ID to the header blockchain database, or may retrieve the data hash and the product ID from the header blockchain database. As shown in figure 3 of the specification. The whole head block chain database system is in a public chain form of a decentralized chain, and data are public and transparent. Preferably, the head blockchain database adopts a POS or POW mechanism, both ordinary users and special users can access the head blockchain database through a Web port, and the authority of the accessed head blockchain database is determined according to the rights and interests of the users. The double-database system of the intermediate node database and the head block chain database is adopted, so that the fluency, the safety and the consistency of the data stored in the evaluation block chain 14 in the whole life cycle are ensured.
The embodiment provides a block chain-based full-life cycle evaluation data system, which combines a block chain and an LCA (link control architecture), provides one-stop service for full-life cycle evaluation and authentication, and ensures the accuracy and fairness of the data system.
