Obviously, the drawings described below are some embodiments of the present invention.

DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Figure 1 A schematic diagram of a process flow of a comprehensive data management method according to an embodiment of the present invention is shown. Figure 1 As shown, a comprehensive data management method according to an embodiment of the present invention includes: Acquire update data in the external participating system, and preprocess and encrypt the update data using the first smart contract to obtain preprocessed encrypted data; Sending the preprocessed encrypted data to a blockchain cluster, and writing the preprocessed encrypted data into a pre-generated block in the blockchain cluster; During the block generation process, the block is signed and the signature is encrypted. After the block generation is completed, the block is added to the blockchain cluster; The GSS service system is used to sense the data update of the blockchain cluster, and the second smart contract is used to process the sensed blocks to obtain the alliance chain data, and the alliance chain data is isolated by the permission system.

[0030] Among them, external participating systems include operators and other aviation information systems. The alliance chain cluster will also record online operator information to ensure that the GSS (Global Support System) service system can quickly perceive the online system and prevent other systems from being offline, resulting in data problems. The GSS service system refers to a comprehensive service platform designed specifically for the aviation information service field. It aims to provide efficient, secure and reliable data management and processing capabilities by integrating multiple data sources and services to support the operational needs of aviation-related organizations such as airlines, airports, and air traffic control agencies.

[0031] In this embodiment, Figure 2As shown in the figure, the consortium chain is a consortium chain network composed of multiple participants. Each participant in the consortium chain network represents a data source, has a certain reputation and qualifications, and is authorized and verified by the GSS service system. By establishing a consensus mechanism, the participants can reach an agreement on data sharing and transmission. In order to ensure the security of the data, the participants need to join the consortium chain network through some form of authentication mechanism and obtain a unique identity. Data of different systems and different security levels use different consortium chains, which ensures that different operators cannot see each other's data, and data of different security levels will not cross.

[0032] Optionally, also include: Starting the blockchain cluster and detecting the blockchain cluster, specifically: detecting the alliance chains of all system environments of the blockchain cluster, and detecting the connection between the alliance chain systems of the blockchain cluster using a heartbeat detection method; After the detection is normal, the leader system is elected using the consensus mechanism.

[0033] In this embodiment, the leader system performs unified data detection on all systems and then provides external services. The detection includes: heartbeat, network, computing power and security self-test. Heartbeat detection is used to determine whether the connected system is normal. Among them, the consensus mechanism adopts DPos equity authorization and has the following characteristics: Efficiency: The DPoS consensus mechanism greatly speeds up the consensus verification process to within seconds by reducing the number of nodes involved in verification and accounting. This makes the DPoS mechanism perform well in processing large numbers of transactions and is suitable for high-concurrency scenarios.

[0034] Energy efficiency: Since the DPoS mechanism reduces the number of nodes participating in the consensus, it consumes less energy than other consensus mechanisms such as PoW and PoS. This helps reduce the operating costs of the blockchain network and reduces the impact on the environment.

[0035] Scalability: The DPoS mechanism optimizes the node selection process, making it easier for the blockchain network to expand while maintaining security. This helps support larger-scale transactions and data storage to meet growing business needs.

[0036] Optionally, establish a connection between the GSS service system and the blockchain cluster, classify the alliance chain system of the blockchain cluster according to different security levels, and formulate a corresponding data exchange protocol for each level; When a user accesses the system, the corresponding smart contract is dynamically loaded according to the user's permissions, and the corresponding alliance chain data is provided.

[0037] In this embodiment, through configuration, the associated alliance chain systems of different security levels are interacted and verified. When the connected alliance chains are ready, the system maintenance engineer will be notified that they can be used normally. When an abnormal alliance chain appears, an alarm notification will be immediately sent to the system maintenance engineer to handle the corresponding problem.

[0038] Optionally, obtaining the preprocessed encrypted data specifically includes: receiving update data, performing verification and data conversion on the update data, and obtaining converted data; The conversion data is encrypted using the national encryption SM4 to obtain pre-processed encrypted data.

[0039] Optionally, writing the preprocessed encrypted data into a pre-generated block in the blockchain cluster specifically includes: Utilizing the blockchain cluster to receive the preprocessed encrypted data, and transmitting the preprocessed encrypted data to the leader system; The leader system is used to perform data verification, and after the verification is completed, the pre-processed encrypted data is written into the pre-generated block.

[0040] Optionally, during the block generation process, signing the block and encrypting the signature specifically includes: The block is signed by a HASH method to obtain a block hash value, and the block hash value is encrypted using the private key of the blockchain cluster.

[0041] Optionally, HTTP protocol and TCP protocol are used to realize the interaction between the alliance chain systems in the blockchain cluster, and TCP protocol / IP protocol is used to establish a communication channel between the blockchain cluster and the external participating system and the GSS service system.

[0042] In this embodiment, Java is used as the development programming language. Heartbeat detection, information transmission, contract processing, etc. are performed through HTTP protocol and TCP protocol.

[0043] Among them, the data transmission between blockchain services and other systems (such as GSS service system, operator system, other systems of Air China, etc.) adopts the P2P interaction model in TCP / IP, and connects to various data sources through the industry's relatively mature WebSocket long connection transmission technology to ensure the rapid circulation and processing of data.

[0044] Optionally, an abnormal alarm mechanism is set up in the external participating system. When any abnormal situation is detected during the data update process, an alarm notification is immediately sent to the system maintenance engineer and a detailed error log is recorded.

[0045] Optionally, establish a smart contract update approval process, and all proposed changes to smart contracts must go through a formal submission, review, and approval process to ensure the security and uniformity of the update.
