Embodiment one:

Generally, the service data management device of the electric power internet of things may be an electric power internet of things system.
The following description will take a main body of a service data management device of the electric power internet of things as an example to execute a service data management method of the electric power internet of things. Referring to fig. 1, the service data management method of the electric power internet of things specifically includes:
S110, the intelligent ammeter determines storage attributes of the service data based on the data type of the current service data, wherein the storage attributes comprise public attributes and private attributes.
The business data management method of the electric power Internet of things aims at selecting a corresponding business data storage mode according to the data type of business data, so that the safety of business data storage and extraction is adaptively improved, the efficiency of data extraction is guaranteed, and the operation of the electric power Internet of things is optimized.
Specifically, referring to fig. 2, in the electric power internet of things system, each smart meter 11 is respectively connected with the public node 12 and the private node 13 in a signal manner, and is used for storing service data of the smart meter 11. The public nodes 12 and the private nodes 13 are arranged in a plurality, and when the intelligent ammeter 11 stores service data, the service data is stored to the public nodes 12 or the private nodes 13 according to the data type of the service data, so that the service data is stored. Correspondingly, the data management node 14 is in signal connection with the public node 12 and the private node 13, and is used for extracting service data stored by the public node 12 and the private node 13 so as to process related services of the electric power internet of things. The smart meter 11 is set corresponding to each electricity utilization unit, and collects and stores relevant service data generated in the household electricity utilization process. The public node 12 and the private node 13 are used for storing service data corresponding to the storage attribute, the public node 12 stores service data of the public attribute, and the private node 13 stores service data of the private attribute. The public node 12 can directly return corresponding service data according to the data request of the data management node 14, and the identity of the data management node is not required to be verified, so that the data management node can conveniently extract relevant service data to perform service processing, the service data processing efficiency is improved, and the operation of the electric power internet of things system is optimized. The private node 13 performs verification of identity validity of the data management node according to the data request of the data management node 14, so as to ensure security of the data extraction process and avoid the situation that the service data is stolen by illegal nodes. And corresponding to one end of the data management node, performing relevant service processing according to the extracted service data, so as to realize service operation processing of the electric power Internet of things system.
When the service data is stored, the intelligent ammeter determines the storage attribute of the current service data based on the data type of the service data. The storage attribute identifies the location where the business data needs to be stored. If the storage attribute of the current service data is a public attribute, the service data is required to be stored to a public node; if the storage attribute of the current service data is a private attribute, the service data needs to be stored to a private node. It will be appreciated that the smart meter generates numerous business data during the daily operation. The data types of the service data comprise user identity information, home address, electricity consumption data, ammeter operation log, safety monitoring data and the like, wherein part of the service data related to user privacy such as the user identity information, the home address, the electricity consumption data and the like is private, and the service data needs to be stored in a private node in order to avoid the fact that the part of the service data is stolen due to data leakage caused by network attack. And for partial service data with lower security requirements, the partial service data can be directly stored to a public node, and the subsequent data management node can directly extract the data when extracting the data, so that the efficiency of extracting and processing the partial service data is improved, and the processing efficiency of related services is further optimized.
Before that, the data management node constructs a mapping relation between each data type and the corresponding storage attribute in advance, and issues the mapping relation to the intelligent ammeter; correspondingly, when the intelligent ammeter determines the storage attribute of the service data based on the data type of the current service data, the intelligent ammeter queries the mapping relation based on the data type of the service data and determines the storage attribute of the service data. The data management node manages the storage attribute of each data type through the mapping relation, and configures the private attribute for each data type according to the actual storage requirement of the business data of each data type if the security requirement is higher and the business data needs to be stored in the private node. Otherwise, if the security requirement of the data type service data amount is not high, in order to facilitate the subsequent efficient extraction and processing of the part of service data, the part of service data needs to be stored to a public node, and then a public attribute is configured for the data type.
In one embodiment, the data management node modifies the corresponding mapping relationship according to the real-time service data storage requirement, and updates the corresponding mapping relationship to the smart meter. It can be understood that, according to the real-time service data storage requirement, if the storage attribute of the service data of a certain data type needs to be changed from a private attribute to a public attribute or from the public attribute to the private attribute, the data management node modifies the storage attribute in the corresponding mapping relationship and updates the modified mapping relationship to the corresponding smart meter, so as to complete the modification of the storage attribute of the service data of the corresponding data type. Further, in the embodiment of the application, after the storage attribute of the corresponding data type service data is modified, the corresponding data type service data stored in the original node is also subjected to storage node migration, and the part of service data is migrated according to the updated storage attribute, so that the service data stored in the corresponding storage node meets the real-time data storage requirement.
S120, the intelligent ammeter splits the service data into a plurality of service data packets which are redundant with each other, the service data packets are distributed and stored to each public node or private node according to the storage attribute of the service data, and the service data packets comprise identification information of the intelligent ammeter and timestamp information corresponding to the service data.
Further, after determining the storage attribute of the service data, the service data may be correspondingly stored to the public node or the private node according to the storage attribute of the service data. The public nodes and the private nodes are arranged in a plurality, and the service data are stored in a distributed mode by using the public nodes or the private nodes, so that the fault tolerance of the service data storage can be improved, the conditions that the data are easy to steal and lose due to the storage of a single node are avoided, and the safety of the service data storage is ensured.
Specifically, the intelligent ammeter splits the current service data into a plurality of service data packets, each data packet comprises partial service data, and each service data packet further comprises partial service data which are mutually redundant, so that the fault tolerance performance of service data storage is further improved. It can be understood that part of service data is redundantly backed up by each service data packet, so that even if the service data of one storage node is lost or the storage node fails, the service data of the rest storage nodes can be extracted, and the complete service data can be restored by the redundant backup service data.
After the intelligent ammeter splits the service data into a plurality of service data packets, each service data packet is further stored to each public node or private node according to the storage attribute of the service data. It should be noted that, each service data packet needs to include identification information of the smart meter and timestamp information of the service data. The subsequent data management node can conveniently query and extract the service data according to the corresponding identification information and the timestamp information.
S130, when a data management node extracts the service data, the data management node sends a data request to each public node or each private node, wherein the data request comprises the identification information and the timestamp information corresponding to the service data;
And S140, each public node returns a corresponding service data packet to the data management node in response to the data request, or each private node performs consensus verification on the identity of the data management node in response to the data request, judges whether the identity of the data management node is legal, and if so, each private node returns the corresponding service data packet to the data management node.
After the storage of the service data is completed, when the data management node needs to extract the corresponding service data, a data request is sent to the corresponding storage node. The data management node determines the storage attribute of the service data to be requested by inquiring the mapping relation, and then sends the data request to the corresponding public node or private node. Correspondingly, the data request comprises time stamp information of the service data to be requested and identification information of the corresponding intelligent ammeter, so that the storage node returns a corresponding service data packet based on the time stamp information and the identification information.
Further, after each public node or private node receives the data request, the response of the data request is correspondingly performed. And each public node extracts the corresponding service data packet according to the identification information and the timestamp information in the data request and sends the service data packet to the data management node. After each public node receives the data request, because the public node does not set a corresponding identity verification means in consideration of improving the efficiency of data extraction processing, when the public node responds to the data request, the service data packet stored in the public node is directly queried according to the timestamp information and the identification information, and the service data packet is returned to the data management node.
And one end of the corresponding private node needs to verify the identity of the data management node when responding to the data request in consideration of guaranteeing the data storage and extraction safety. Referring to fig. 3, each private node performs consensus verification on the identity of the data management node in response to the data request, and determining whether the identity of the data management node is legal includes:
s1401, each private node verifies the identity of the data management node according to pre-stored verification information, a first identity verification result is generated, the first identity verification result is summarized to a designated consensus node, the consensus node is selected from a plurality of private nodes in advance, and the verification information is stored in each private node by the data management node in advance;
and S1402, the consensus node generates a consensus verification result based on each first identity verification result, and determines whether the identity of the data management node is legal or not based on the consensus verification result.
The embodiment of the application adopts a block chain-based consensus verification mode to carry out the identity verification of the data management node. Before that, the legal data management node stores authentication information of its own identity in each private node in advance for subsequent authentication of the private node. When a data request response of the data management node is carried out, the private node compares the authentication information stored by the private node with the authentication information provided by the data management node in real time, and the authentication information can be sent to the private node together with the data request. And judging whether the verification information and the verification information are consistent according to the verification information comparison result, and outputting a corresponding first identity verification result. Considering that a single private node has the influence of network attack and manipulation, the embodiment of the application does not directly take the identity verification result of the single private node as a final identity verification result. But performs the consensus verification based on the first authentication result of each private node to determine the final authentication result. And selecting one private node from all the private nodes as a consensus node, and summarizing the first identity verification result of each private node by the consensus node to perform consensus verification. And the common identification verification adopts a mode of minority compliance, and if the first identity verification result judges that the identity legal proportion of the current data management node exceeds 50%, the identity legal proportion of the data management node is determined. Otherwise, the current data management node is not legal, the data request is ignored, and the data request response is not carried out on the current data management node. After verifying that the data management node is legal, each private node extracts the corresponding service data packet according to the identification information and the timestamp information in the data request and sends the service data packet to the data management node, so that the response of the data request is completed.
