Industrial edge side data sharing system based on combination of active identification and block chain technology

Abstract

The invention discloses an industrial edge side data sharing system based on combination of active identification and a block chain technology. The data sharing system stores factory equipment data; the factory equipment end queries factory equipment data through the data sharing system; the data sharing system comprises a plurality of active identification modules, a factory key management center, a plurality of routing gateways, a plurality of edge side devices and a block chain. According to the industrial edge regionalization data sharing system based on combination of the active identification and the block chain, data interconnection and intercommunication between equipment in a factory are realized, meanwhile, the data active capability is enhanced, malicious data tampering is prevented, and the production efficiency of a production line of the factory is improved.

Description

technical field [0001] The invention relates to the fields of industrial Internet identification analysis, data security, encryption authentication and edge data sharing, in particular to an industrial edge data sharing system based on the combination of active identification and block chain technology. Background technique [0002] The Industrial Internet is a new model and new ecological network infrastructure for the integration of information and communication technology and industrial economy. According to statistics, the total scale of China's industrial Internet market in 2020 has reached 671.27 billion yuan. According to valid data, it is predicted that the industrial Internet market will reach one trillion yuan by the end of 2021. With the advancement of the industrial Internet construction process, and a large number of funds involved , the development of the Industrial Internet has become the focus of national and even global attention. [0003] Although my count...

Problems solved by technology

[0003]Although my country's manufacturing industry has developed steadily in recent years, due to the huge volume of my country's manufacturing industry, the overall level of equipment informatization and intelligence is lagging behind, and due to the large number of equipment and production lines The long-term causes difficulty in equipment data sharing and storage, lack of "initiative" in equipment data, and lack of security in data transmission and storage, resulting in low production efficiency in the factory and untimely operation and scheduling outside the factory

Due to the unopened interfaces of some devices and the non-sharing of data, data cannot be shared between factory devices, and the status of devices is difficult to synchronize. There are serious "data islands" within the enterprise. This series of problems seriously restricts the development of my country's industrial Internet.

[0004] Existing data sharing methods are mainly divided into two categories. The first category uses third-party database sharing methods, mainly by storing data generated by different devices and platforms in The database realizes cross-domain, cross-platform and cross-system access, but this method relies too much on the initiative of the platform, and it is necessary to send collection instructions to realize passive collection and return of device data, and the security of data storage cannot be guaranteed. Data is easily tampered with illegally; the second type is through memory sharing. After the device completes data collection, the data is transferred to the shared memory resource pool of the device. Equipment and cross-regional data sharing, but this method consumes too much storage resources on the equipment side, and once the control data is intercepted by hackers, factory equipment and systems are vulnerable to attacks, which can seriously lead to equipment shutdown and factory shutdown, resulting in economic losses

Facing the lack of initiative of factory equipment data, low security and lack of regional data sharing mechanism inside and outside the factory, how to break the "data island" between factory equipment, ensure data security, and realize safe data sharing among regional equipment inside and outside the factory , has become an urgent technical problem to be solved in the safe sharing of industrial Internet data
