Detailed Description
The invention is further described below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
Example 1
The embodiment introduces a storage synchronization method and a storage synchronization device for parameter change records of a power grid monitoring master station system, and the method comprises the following steps:
be applied to electric wire netting control master station end service node, include:
receiving parameter change information of equipment operation sent by a client; the client is used for receiving a request for initiating equipment operation parameter change by a user and organizing parameter change information;
analyzing the parameter change information to obtain a client user mark, checking the existence of a user according to a permission database, and checking whether the user has the permission for modifying and setting the equipment parameters;
after the user is confirmed to be qualified, identifying parameter change information, calculating hash values aiming at each group of change information, further calculating new hash values for the hash values of two adjacent groups, and finally calculating a root hash value of a binary tree according to a binary tree mode;
taking the calculated root hash value as a part of information of a block header, wherein the block header comprises a user mark, request time, a father block hash value, a random number and workload certification information;
the service node N which completes block head assembly broadcasts the whole block information, after other service nodes receive the block information, the validity of the block is verified, and if the block is valid, the block is added into a local latest block chain; and changing parameters in the local equipment library according to the parameter change record information in the block, replying confirmation information to the sending node N after the change is completed, and updating the change of the parameters in the local equipment library after the node N receives more than half of the node confirmation.
In the method for storing and synchronizing the system parameter change records of the power grid monitoring master station, the device operation parameter change records are stored in a block mode, and the device operation parameter changes are organized in a block mode and stored in a block chain mode in a distributed power grid monitoring master station server. The storage process of the parameter change record is shown in fig. 1, and the application process specifically involves the following steps:
step 1, a client user initiates an equipment operation parameter change request, and organizes complete request information including user identification, request time, an equipment unique code, an equipment parameter name, a parameter before equipment change and a parameter after equipment change, wherein the request information can include one or more groups of parameter change records consisting of operation time, an equipment unique code, an equipment parameter name, a parameter before equipment change and a parameter after equipment change. And the client broadcasts the organized request information to each service node of the power grid monitoring master station.
Step 2, after each service node of the power grid monitoring master station receives a request of the client, firstly analyzing a user mark of the client, checking the existence of the user according to the permission database, and checking whether the user has the permission of modifying and changing the equipment parameters.
And 3, after the service node of the master station side confirms that the parameter change request user is qualified, further identifying change information such as each group of operation time, unique equipment code, equipment parameter name, parameters before equipment change, parameters after equipment change and the like, calculating hash values aiming at each group of change information, further calculating new hash values for the hash values of two adjacent groups, calculating the hash values layer by layer according to a binary tree mode, and finally calculating a root hash value of a binary tree. The process of specifically calculating the root hash value is shown in fig. 2: firstly, an SHA256 hash algorithm is adopted for each change record (the hash algorithm is a method for creating small digital codes from any kind of data, wherein the SHA256 hash algorithm can generate a hash value with a length of 256 bits for any length of information), a hash value with a fixed length of 256 bits is generated for each piece of change record information, a leaf layer L1 of a binary tree is formed, then a new hash value is calculated by inputting the SHA256 hash algorithm according to two adjacent groups of hash values, if a single hash value exists, a copy is copied by the self, and then the new hash value is calculated by inputting the hash algorithm, so that a second layer L2 of the binary tree is formed. And analogizing to finally calculate the hash value of the highest layer of the binary tree, namely the root hash value. The root hash value calculated in this way can guarantee the order of the change information, and any fake change or illegal operation for adjusting the change order can be identified.
And step 4, the service node of the master station end takes the calculated root hash value as a part of information of the block head, and the block head comprises user identification, request time, a father block hash value, a random number and workload certification information, as shown in fig. 3. Wherein the random number and the workload certification information are for the other nodes to authenticate the validity of the workload of the block. Method and process of workload certification: and (2) a special state estimation calculation method for the power grid monitoring master station system is adopted (the state estimation calculation can obtain the state estimation value of each device after matrix calculation according to the section data of the power grid device and a power grid model). And acquiring a data section of corresponding time according to the request time, calculating a state estimation process by combining with a power grid structure of the equipment model base, and then taking a power value of a position corresponding to the random number in the line table in a calculation result as workload certification information. If the random number is greater than the number of the line equipment, performing modulo operation on the number of the line equipment to obtain an integer less than the number of the line equipment, and then acquiring a power value of a position corresponding to the value in the line table to be used as a workload certificate to be placed in a block head.
And step 5, the service node (node N for short) at the master station end completes the assembly of the block header, and constructs the parameter change record and the block header together into a complete parameter change record block, wherein the structural information of one block is shown in fig. 3. After the block assembly is completed, the node broadcasts the whole block information, after other service nodes receive the block information, the validity of the block is verified, and if the block is valid, the block is linked with the local block chain. And completing the change of the parameters in the local equipment library according to the parameter change information in the block, and after the change is completed, replying confirmation information with the sending node N, and after the node N receives more than half of the node confirmation, updating the change of the parameters in the local equipment library. The specific procedure of the broadcast processing mechanism of the node N is described as follows: (1) the node N issues block information, and other service nodes calculate a root hash value according to the received change record information in the block body by the method in the step 3, and compare the root hash value with the root hash value in the block header information to verify the validity of the parameter change information; (2) the other service nodes further obtain a data section according to the request time in the block head and calculate a primary state estimated value by combining the power grid structure of the equipment model base, further obtain the numerical value of the corresponding position of the corresponding line table and the random number according to the random number in the block head, and compare the numerical value with the workload certification information provided in the block head, if the numerical values are consistent, the workload certification is effective, namely the block is effective; (3) and finally, the other service nodes compare the parent block hash value in the block head with the local parent block hash value, if the parent block hash value is consistent with the local parent block hash value, the latest block received this time is linked with the local block, and meanwhile, a confirmation message is replied to the sending node N.
The invention provides a storage synchronization method for parameter change records of a distributed power grid monitoring master station system, wherein the synchronization method for the operation parameter change records of equipment comprises the following steps: any two service nodes of the distributed power grid monitoring master station system can synchronize parameter change block chains. The synchronization mode is as follows:
(1) if the lengths of the local blockchains of the two serving nodes are different and the long block contains a short blockchain, the node with the short blockchain automatically synchronizes the missing block from the node with the long blockchain. As shown in fig. 4, the parameter change blockchain in the node a sequentially includes (block 1, block 2, block 3), the parameter change blockchain in the node B sequentially includes (block 1, block 2, block 3, block 4), the blockchain length of the node B is longer than that of the node a, and the blockchain of the node a is included, the blockchain of the node a automatically follows the synchronization block 4 of the node B;
(2) if the two node parameter change block chains are forked, namely, a part of parent blocks in the two block chains are the same, starting from the first forked block, the two nodes broadcast a block synchronization request, and the block with more than half recovery confirmation is regarded as a valid block, and the other invalid block is automatically synchronized by the valid block. As shown in fig. 5, the parameter change blockchain in the node C sequentially includes (block 1, block 2, block 3, block 5), the parameter change blockchain in the node D sequentially includes (block 1, block 2, block 3, block 4), and if the two blockchains in the node C and the node D have a conflict in the 4 th block, the node C and the node D distribute and transmit broadcast information to confirm the 4 th block, and if more than half of the nodes confirm that the block 5 is valid, the node D synchronizes the block 5 from the node C to the local blockchain.
By the synchronization method, the same parameter change block chains of all service nodes in the whole network can be ensured. Therefore, the consistency of the running parameters of the power grid monitoring system equipment is ensured, and meanwhile, the parameter change records are synchronized point to point between any two service nodes, so that the problems of single node failure of centralized updating and the loss of parameter change setting in the process of main-standby switching can be solved.
