Detailed Description
As shown in fig. 1, in the power system, the power data mainly includes: marketing data, ERP data, comprehensive data, production data and the like are collected based on a data center, and data sharing is realized in the power system.
In a power system, information safety is important, if data is only transmitted internally in an interactive mode, the probability of information leakage is low, but if the data is shared power data, the power data cannot be well utilized and shared due to the fact that the information safety is emphasized too much, and the due effect of the data is not exerted. The block chain can be applied to solve the problem, the power data sharing mechanism based on the block chain can ensure that data is hardly tampered, encrypted for transmission and traceable, the problems of potential safety hazards and data leakage are solved, and the method is a perfect solution. The power data sharing needs to be composed of a power data sharing chain (block chain system) and a data sharing platform. The data sharing comprises the following steps:
the method comprises the following steps: the demand side system requests a data sharing and delivering algorithm from the data sharing platform;
step two: the data sharing platform requests to link the power system sharing chain, and applies for authorization to a data owner system;
step three: after the data owner authorizes the data, the data sharing platform links the power data sharing chain authorization information;
step four; the data commonality platform applies for a data report from the data center and delivers an algorithm;
step five: the data center builds a sandbox and generates a report according to a delivery algorithm;
step six: the data center returns a report to the data sharing platform after filtering through keywords, and the data sharing platform carries out information chaining to the electric power data sharing chain report;
step seven: the data sharing platform returns a data report to the demander system, and the demander system returns report receiving information to the data sharing platform;
step eight: the data sharing platform reports the acceptance of the information uplink completion.
As shown in fig. 2, the blocks of the power block chain are divided into two parts, block head and block body respectively. The block header contains version number, previous block hash, current block hash, timestamp, random number, signature for block header portion, etc.; the zone block contains information of the power equipment, such as location of the equipment, access control policy of the equipment, model of the equipment, and the like.
As shown in fig. 3, the system architecture of the power data information application platform mainly comprises a base layer and an application layer, and is connected through a standard interface, specifically:
and the basic layer is mainly used for storing and identifying data, the sequencing node sequences the data according to an algorithm, packages the data into an original data block, and approves the original database through digital signature. When a sufficient number of approved data blocks are obtained, a consensus is formed. The base layer also supports a hybrid data storage schema of data blocks and databases. By verifying the data in the block chain and verifying that the data cannot be tampered, a more real-time, flexible and efficient data query function is realized, and the data with a question can be verified on the block chain;
and the application layer supports various application scenes of the power system and data circulation and log retention among the scenes. There are 3 standard interfaces between the application layer and the base layer:
(1) RESTful interface
The interface realizes the standard encapsulation of the information system inquiry and access functions, and the application layer accesses the bottom layer data in an encapsulation mode.
(2) Intelligent contract interface
This interface enables data access translation between RESTful and the blockchain system.
(3) Database access interface
The interface can efficiently access data.
In the power system, the problem of data sharing and exchange of a plurality of information systems exists, the whole process of data sharing is recorded through a block chain technology, full-flow encryption transmission is realized, and the data security is ensured and data leakage is prevented by using a special shared data report mode. The invention breaks the information barrier of the industry, improves the utilization rate of information resources and promotes the development of power enterprises.
