Networked collaborative manufacturing key information interaction system based on block chain technology

Abstract

The invention discloses a networked collaborative manufacturing important information interaction system based on a block chain technology, which belongs to the field of networked collaborative manufacturing, and specifically comprises a cloud service layer which is used for providing manufacturing service and comprises an information tracing module and a cloud production line module; a block chain service layer is used for providing block chain service for a bottom-layer manufacturing enterprise and comprises a gateway information access interface module and a block chain database module; a manufacturing enterprise layer is used for providing a product collaborative production service and comprises a resource virtualization module and a customs information ontology module; a system is oriented to a manufacturing enterprise accessed to a cloud platform, and in a collaborative manufacturing process, when upstream and downstream enterprises of a supply chain perform production information interaction, key information of the enterprises is saved through an upper chain of a block chain network, so that the security and privacy of the information are greatly improved.

Description

technical field [0001] The present invention relates to the field of networked collaborative manufacturing, especially an interactive method for key information of upstream and downstream enterprises in the supply chain based on cloud manufacturing mode, specifically a networked collaborative manufacturing key information interaction system based on blockchain technology . Background technique [0002] The networked collaborative manufacturing model is the extension and development of the cloud manufacturing system, which integrates advanced information technology, manufacturing technology and intelligent IoT technologies, builds a cloud sharing platform, integrates manufacturing capabilities and resources in the industrial Internet environment, and provides global, The high-value cloud service develops "manufacturing in the cloud" into "collaborative manufacturing as a service". The traditional manufacturing industry is more oriented to the product itself and the service i...

Problems solved by technology

[0003] Nowadays, there are a large number of actually running cloud manufacturing service platforms, but when these platforms are connected with the bottom-level enterprises, there are scattered information, lack of mutual trust, low degree of information sharing, authenticity and reliability of information among various participants. Difficult to guarantee, difficult to trace data, easy to leak user information privacy, weak anti-risk ability of the system, prone to single point of failure and cause system paralysis, etc.
