It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a power grid internal and external network data interaction system according to an embodiment of the present invention, where the power grid internal and external network data interaction system is applied to a target power grid, and a forward and reverse isolation device is installed between an internal network and an external network of the target power grid.
The power grid internal and external network data interaction system comprises:
a first blockchain module 11, a first interlinking device 12, a second blockchain module 13 and a second interlinking device 14.
The first blockchain module 11 and the first chain spanning device 12 are both arranged in an intranet of a target power grid, and the intranet alliance chain corresponding to target power grid intranet data is pre-established in the first blockchain module 11.
The second blockchain module 13 and the second chain spanning device 14 are both arranged in an external network of the target power grid, and the second blockchain module 13 is pre-established with an external network alliance chain corresponding to the external network data of the target power grid.
When the intranet data is transmitted from the intranet to the extranet, the first inter-link device 11 down-links the intranet data on the intranet alliance chain to the intranet database. The second chain crossing device 14 obtains the intranet data from the intranet database through the software package provided by the forward and reverse isolation device, and links the intranet data to the extranet alliance chain.
When the extranet data is transmitted from the extranet to the intranet, the second chain crossing device 14 downlinks the extranet data on the extranet alliance chain, and stores the extranet data in the intranet database through the software package provided by the forward and reverse isolation device. The first inter-link device 11 obtains the extranet data from the intranet database, and links the extranet data to the intranet alliance chain.
In this embodiment, the data source of the target power grid is the intranet of the target power grid, and the data is stored in the intranet more safely, so to implement the link chain for the certificate of the original data, a block chain alliance chain can be established in an internal network environment, and an interface is opened for internal application in the intranet to implement the link chain for the internal data. The first blockchain module 11 is a carrier of the intranet alliance chain.
In this embodiment, part of data of the power grid needs to be provided for the external network for use, and on the other hand, the power grid needs to acquire the data from the external network, so that a block chain alliance chain can be further established in an external network environment, the alliance chain can be connected with an external network organization, and the power grid can provide the data to the outside through the alliance chain and can also acquire the data provided by the external network organization through the alliance chain. The second blockchain module 13 is a carrier of the extranet alliance chain.
In order to ensure data security, a forward and reverse isolation device is installed between an internal network and an external network, so that a system of the internal network and the system of the external network cannot be directly connected by a Transmission Control Protocol (TCP), data interaction can be realized only by writing Structured Query Language (SQL) statements by using a software package provided by the forward and reverse isolation device, and the software package only supports Java Language. That is to say, the intranet block chain nodes and the extranet block chain link nodes cannot directly perform TCP communication, so the first inter-chain device 12 and the second inter-chain device 14 are provided in the embodiment of the present invention, and the communication between the intranet alliance chain and the extranet alliance chain is realized by combining with the existing forward and reverse isolation device of the target power grid.
As can be seen from the above description, unlike the scheme in the prior art in which only an intranet or only an extranet is used to build a federation chain, in the embodiment of the present invention, a first blockchain module and a second blockchain module are respectively arranged in the intranet and the extranet of a target power grid, that is, two federation chains are built in advance. On the basis, the embodiment of the invention is provided with the chain crossing devices corresponding to the internal network and the external network, realizes data interaction between the internal network alliance chain and the external network alliance chain through the chain crossing devices corresponding to the internal network and the external network and the original forward and reverse isolation devices of the power grid, also solves the problem that the block chain technology cannot penetrate through the direct communication of the internal network and the external network of the power grid, and further realizes the safe transmission of the data of the internal network and the external network of the power grid.
