specific Embodiment 1

[0027] figure 1 A flow chart of an embodiment of a method for sharing shipbuilding inspection data according to the present invention is shown, and the method includes the following steps:

[0028] S1: Receive the first data block uploaded through the first local area sub-chain, and save the first data block.

[0029] Generally speaking, the block part of the data block of the blockchain records the transaction data, while the block in the data structure proposed in this paper mainly records the ship inspection data. This data structure can realize that the verification data on the block can be traced by the pre-selected node and exert influence on the information of the subsequent node of the block. Cooperating with corresponding encryption methods can ensure that malicious attacks cannot tamper with useful information, thereby ensuring data security and integrity. Therefore, the present invention provides a data block with a new data structure, the data block is divided in...

specific Embodiment 2

[0044] In addition to the above method, the present invention also provides a sharing alliance chain of shipbuilding inspection data. image 3 A structural diagram of an embodiment of a sharing consortium chain of shipbuilding inspection data according to the present invention is shown.

[0045] Such as image 3 As shown, this embodiment provides a shared consortium chain 1 for shipbuilding inspection data. The shared consortium chain 11 includes a client terminal 111 , an institutional cross-region main chain 112 , multiple local-region sub-chains 113 and an authorized sub-chain 114 .

[0046] Wherein, the client 111 is respectively connected to the corresponding local area sub-chains 113, and the multiple local area sub-chains 113 are respectively connected to multiple nodes of the institutional cross-area main chain 112 through side chains, and the authorized sub-chain 114 Connect with the organization's cross-regional main chain 112 through the interconnection chain.

specific Embodiment 3

[0052] The invention also provides a system for sharing shipbuilding inspection data. Figure 4 A structural diagram of an embodiment of a system for sharing shipbuilding inspection data according to the present invention is shown.

[0053] A system 1 for sharing shipbuilding inspection data, characterized in that the sharing system includes multiple shared consortium chains 11 for shipbuilding inspection data as described above, wherein the organization of each shared consortium chain 11 cross-regional main chain 112 are connected through parallel chains, so that cross-sharing can also be realized between multiple sharing alliance chains 11, thereby expanding the scope of sharing.

[0054]The present invention provides a system for sharing shipbuilding inspection data. By dividing the business data and external service data in the inspection data, the external service data is only uploaded through local area sub-chains during the upload process, and only through the external ...

Abstract

The invention discloses a Ship manufacturing inspection data sharing method, an alliance chain and a sharing system. The shared alliance chain comprises a user side, a mechanism cross-region main chain, a plurality of local region sub-chains and an authorization sub-chain. The sharing system comprises a plurality of shared alliance chains of shipbuilding inspection data. According to the sharing method, the alliance chain and the system, business data and external service data in inspection data are divided, the external service data are uploaded only through a local area sub-chain in the uploading process, authorization verification and verification are carried out only through an authorization sub-chain in the sharing process, and the data are shared after verification is passed. According to the sharing method, the alliance chain and the system, the improvement of the data sharing speed, the access limitation and the security and stability is realized, and the reduction of the data sharing cost is ensured on the basis of saving the shared data storage space.

Description

technical field [0001] The invention relates to the field of sharing of shipbuilding inspection data, and relates to a sharing method, alliance chain and system of shipbuilding inspection data. Background technique [0002] Shipbuilding inspection has multiple business scenarios such as drawing information, certified product list and inspection application list, and each business scenario has a corresponding information collection mechanism. In addition, data testing involves a wide range, and there are cross-institutional transactions between different institutions. [0003] In the existing technology, the main workflow of the data sharing model is generally that the data provider publishes and stores the collected data on the central storage platform or server, and the data demander retrieves the data from the platform and checks the relevant description information of the data. Determine the required data and apply to the platform to obtain the data. The traditional shi...
