And the system verifies and confirms the data by adopting a PBFT consensus algorithm to ensure that the data cannot be tampered. And the airline main chain unidirectionally synchronizes fragmented data, and a global traceability view is formed through integration. The cross-fragmentation communication protocol is based on Hash locking and a notarist mechanism, and the security of data interaction is guaranteed. And the anti-metal RFID tag and the block chain data are irreversibly mapped, so that errors or forgery caused by manual input is avoided. And the main chain stores the Merkle Root hash of the fragments and is used for verifying the authenticity of the data. According to the method, credible traceability of the aerial material full-link data is realized, the cross-domain cooperation efficiency and the data security are improved, and the aerial material purchase prediction accuracy is optimized.

Description

Technical Field

[0002] Aircraft material management is a critical component of aviation operations, encompassing multiple processes including procurement, transportation, storage, use, and maintenance. Traditional aircraft material management systems primarily rely on single-function ERP systems, such as the SAP aviation module, which only manage inventory and fail to meet the requirements of full-chain traceability. While blockchain technology has recently gained traction in supply chain management, existing blockchain applications (such as public blockchains like Ethereum) face performance bottlenecks (low throughput and high latency), making them inadequate for the high-concurrency queries and fast uploads required by aircraft material management systems. Furthermore, while existing Mojix RFID systems and RFID baggage tracking systems have achieved some success in internal data management, they suffer from limited data sharing, reliance on centralized systems, a lack of cross-domain data collaboration, and insufficient data security. These systems fail to achieve complete data collection, real-time cross-domain collaboration, and data immutability throughout the aircraft material lifecycle. This results in incomplete traceability information, low data credibility, and inefficient traceability, making them unable to meet the aviation industry's stringent requirements for full-lifecycle aircraft material management.

[0031] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0032] It should be noted that the steps shown in the flowcharts of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and that, although a logical order is shown in the flowcharts, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0033] Purpose of the present invention:

[0034] 1. Establish an airline-led data acquisition mechanism;

[0035] Through blockchain sharding technology, suppliers and transportation companies are required to upload data to the airline system, and the entire chain data of aviation materials from production to retirement (production parameters, logistics tracks, maintenance records) are centrally controlled by the airline.

[0036] 2. Ensure that data cannot be tampered with;

[0037] Data uploaded by suppliers and shippers must be verified by PBFT consensus and ultimately confirmed by the airline's node before being uploaded to the blockchain. External parties cannot modify historical records. Blockchain's decentralized storage and sharding isolation prevent the risk of single-point tampering.

[0038] 3. Realize automated cross-domain collaboration;

[0039] Data submission rules are set through smart contracts. Suppliers must submit quality inspection reports when aviation materials leave the factory, and transportation companies must upload location and temperature and humidity data in real time. For suppliers / transporters who fail to submit data as required, the system will automatically trigger an early warning and record their credit rating.

[0040] Example 1

[0041] like Figure 1 As shown, this embodiment provides a multi-domain scenario aviation material management method based on blockchain sharding and RFID, including the following steps:

[0042] Basic information of aviation materials is collected through RFID tags and divided into production, logistics and maintenance segments according to business domains;

[0043] Data exchange between different shards based on the cross-shard communication protocol;

[0044] Integrate data from all shards through the airline main chain to obtain a global traceability view;

[0045] Each shard uses the PBFT consensus algorithm to verify and confirm data;

[0046] The airline main chain stores the Merkle Root hash of each shard to verify the authenticity of the data returned by each shard.

[0047] Furthermore, each shard stores and processes data independently, and suppliers and transporters can only access their own shards.

[0048] Furthermore, after the RFID tag is scanned, it automatically triggers the data to be uploaded to the chain, and the tag ID and the data on the chain form an irreversible mapping.

[0049] Furthermore, the cross-shard communication protocol is implemented based on hash locking and notary mechanisms.

[0050] Furthermore, the PBFT consensus algorithm verifies the data submitted by suppliers or transporters through several nodes within the shard, and the airline node has the final veto power.

[0051] like Figure 1 As shown, this embodiment also provides a multi-domain scenario aviation material management system based on blockchain sharding and RFID, including:

[0052] The data collection module is used to automatically collect basic information of aviation materials through RFID tags, including production batches, specifications and quality inspection data;

[0053] The sharding module is used to divide the basic information of aviation materials into production shards, logistics shards, and maintenance shards according to business domains, and each shard processes data independently;

[0054] The airline main chain is used to integrate data from all shards and generate a global traceability view;

[0055] The cross-shard communication module is used for data interaction between different shards.

[0056] like Figure 2 As shown, transaction processing and sharding work together as follows:

[0057] The system utilizes transaction sharding technology to achieve efficient processing in the aviation material trading and circulation process. Shards are divided according to transaction type and scale. For example, transactions of different business types, such as aviation material purchase orders and transfer instructions, are assigned to corresponding business transaction shards. Small, routine purchases of aviation materials and accessories are quickly processed by shards composed of nodes with corresponding ordinary computing power. Large-scale aviation material and equipment procurement contracts, which involve complex approval processes and the involvement of multiple parties, are handled by high-performance shards composed of a corresponding number of nodes equipped with complex computing capabilities to ensure transaction security and compliance.

[0058] Shards collaborate through a cross-shard communication protocol. For example, when aviation materials flow from the manufacturer to the logistics chain, the production data shard interacts with the logistics data shard. A cross-shard communication protocol ensures accurate and secure data transmission between shards, enabling seamless information flow throughout the entire aviation material supply chain. Currently, mainstream protocols are based on hash locking and notary mechanisms. This project's system references the internationally used sharded blockchain Ethereum system, incorporating these technologies to implement a cross-shard communication protocol.

[0059] like Figure 3 As shown, network sharding and node management are as follows:

[0060] The system uses network sharding technology to group nodes based on the entities involved in material management. Nodes belonging to different entities, such as airlines, material suppliers, and transportation companies, are assigned to their own shards. Each node within a shard is responsible for processing transaction verification and data maintenance related to its specific region or entity, effectively distributing network load and preventing congestion caused by a surge in transactions from a single entity or region.

[0061] Each shard uses a distributed algorithm to reach consensus, ensuring data consistency and accuracy. Airline nodes use the PBFT algorithm to verify and confirm aviation material usage records, ensuring data credibility. This algorithm is currently used by many large enterprises to ensure consensus. For example, Ant Financial has built a blockchain-based cross-border remittance system based on the Practical Byzantine Fault Tolerance (PBFT) algorithm. This ensures that every node can participate in transaction verification and consensus, ensuring the consistency and accuracy of transaction information.

[0062] There are a main chain and a cross-shard coordination chain in the system. The main chain plays a role in basic support and global management, while the cross-shard coordination chain is responsible for coordinating interactions between different shards.

[0063] The system is divided into airline shards, supplier shards, transportation company shards, and regulatory agency shards. Each shard is connected to the main chain and the cross-shard coordination chain through anchor nodes, and cross-shard data transmission and interaction are achieved with the help of relay transactions.

[0064] Each shard has a PBFT (Practical Byzantine Fault Tolerance) consensus group within it, utilizing the PBFT consensus algorithm to ensure the consistency, security, and reliability of transaction verification and block generation within the shard. Each shard's PBFT consensus group packages processed information onto the blockchain, driving the operation of the blockchain network and ultimately achieving trusted traceability of aviation materials across the entire process among different participants.

[0065] like Figure 4-5 As shown, take the PBFT consensus process of an airline as an example:

[0066] The CA certificate node serves as the cornerstone of the airline shard. This node is responsible for issuing certificates, ensuring the authenticity and legitimacy of nodes within the network and providing a strong security barrier for subsequent processes. Endorsing nodes that receive a certificate are responsible for endorsing aviation material maintenance transactions, effectively signing and approving them.

[0067] When a client submits an aviation material maintenance transaction, the leader node first enters the pre-prepare phase, performs preliminary processing on the transaction, and broadcasts a pre-prepare message to the verification node. Upon receiving the message, the verification node enters the prepare phase using the PBFT algorithm, communicating with each other and exchanging prepare request messages to verify the legitimacy of the transaction. After each node reaches consensus using the PBFT algorithm, the commit phase begins. The verification node sends a commit request to the leader node. After collecting sufficient requests, the leader node confirms the transaction and adds it to the blockchain, simultaneously providing transaction confirmation information to the client. Throughout this process, the PBFT algorithm ensures that each node can reach consensus on the transaction even in the presence of faulty or malicious nodes, ensuring the consistency, security, and reliability of blockchain processing of aviation material maintenance transactions within the airline shard.

[0068] This embodiment also builds a prediction model based on historical blockchain data (failure rate, consumption rate) to automatically generate procurement recommendations. The data is tamper-proof and ensures the authenticity of the training set.

[0069] The present invention has achieved the following effects:

[0070] This invention uses smart contracts to force suppliers / shippers to submit data in real time (e.g., upload quality inspection reports upon shipment). Airlines can query full-chain information (production + logistics + maintenance) in seconds.

[0071] The data in this invention is verified by PBFT consensus and then uploaded to the chain. Suppliers cannot unilaterally modify the confirmed data. The airline main chain stores the hash summary of each shard. When the shard node returns forged data, the hash comparison fails.

[0072] The above are merely preferred embodiments of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
