Detailed Description
The technical solutions of the present invention will be further described below with reference to the accompanying drawings, but the present invention is not limited to these embodiments.
The application scenario of the method is that in a power system, power grid information is often a large and complete complex data structure, the amount of power grid information is huge, when a power grid topological graph of a power grid resource management system (PMS) is changed due to engineering construction, a Distribution Automation System (DAS), a rush-repair system, a maintenance platform and a mobile operation system all need to be updated synchronously in time, and when a power distribution terminal is added by the DAS, the DAS also needs to be sent to an equipment resource account corresponding to the PMS Data ownership and peer-to-peer issues.
In order to solve the above technical problems, the present invention provides a method for implementing power grid information sharing based on a block chain technology, which uses the block chain technology to achieve the purpose of sharing power grid information in time, as shown in fig. 1 to 3, and comprises the following steps:
s1: and (3) formulating an intelligent contract based on the block chain technology:
s11: the multi-party system is used as a sharing node to jointly make a commitment, program the commitment in an electronic form and generate an intelligent contract;
s12: the intelligent contracts are diffused and stored in a block chain through a P2P network;
s13: and the intelligent contract of the block chain automatically executes checking, verifying and storing.
The system needing to share the power grid information participates in the block chain, and each system grasps a pair of public key and private key to guarantee the authority of the system in the block chain. Each system commonly agrees a commitment as required, the commitment specifies the rights and obligations of both parties, then the commitment is programmed in an electronic form, and each system is signed by a private key which is mastered by each system so as to ensure the validity of the contract. Through the mutual recognition of the systems, a certain system is selected as a consensus node of the block chain, and the consensus node is used as an execution node to transfer the intelligent contract into the block chain network.
When a certain system performs service processing, such as addition, modification and deletion of power grid information, basic information such as identity identification and credit status of the certain system is verified, then digital signature is performed by using a private key, a shared form is made and booked, then a query request is initiated to other systems for verification, and the verification is spread to related service systems on the whole block chain through a P2P network.
When the shared form is transmitted to the whole network, each system temporarily caches the received form in the block, as long as one system inquires the previous shared form of the information, all the forms recorded in the block with the time stamp are transmitted to the whole network and are checked by other mechanisms of the whole network, and finally, a shared total form is generated.
S2: sharing of power grid information is achieved based on formulated intelligent contracts:
s21: when any system needs to inquire the power grid information, an inquiry request is initiated and is diffused through a P2P network;
s22: other systems verify after receiving the request;
s23: after the verification is passed, other systems transmit the query result to the consensus node through P2P, and simultaneously, the query result is signed and then fed back to the system initiating the query request;
s24: the consensus node packs the transaction into a blockchain;
s25: triggering an intelligent contract and transaction backup so as to complete the sharing of the power grid information through the block chain.
After system information on the block chain is verified, the system information is fed back to the request system through the digital signature to remind the existing information, so that the information is prevented from being re-recorded, incomplete information is fed back, and wrong information is revealed, so that the request system makes a reasonable decision.
After the system on the block chain signs the shared form, the shared form is gathered into a shared total form after being transmitted and verified through P2P, the shared total form is uploaded to the block chain through the consensus node, then the block chain is backed up through an intelligent contract and cannot be tampered, and the requirement of next sharing can be safely, reliably and conveniently met. The mode changes the traditional push type sharing of an information source end system into the information sharing of firstly pulling and then pushing, and achieves the purposes of one-time sharing and multiple use.
The power grid information collaborative sharing mode based on the block chain has the advantages of the traditional point-to-point information sharing mode and the information resource management center information sharing mode, not only can realize point-to-point information sharing exchange among a plurality of systems, but also realizes decentralization and distrust, and simultaneously can realize backup, and realize one-time sharing, multiple use and information traceable management, so that the range and the efficiency of information sharing are greatly increased.
Various modifications or additions may be made to the described embodiments or alternatives may be employed by those skilled in the art without departing from the spirit or ambit of the invention as defined in the appended claims.
