In order to make the objects, technical solutions and advantages of the present application more apparent, specific embodiments of the present application will be described in detail with reference to the accompanying drawings. It is to be understood that the specific embodiments described herein are merely illustrative of the application and are not limiting of the application. It should be further noted that, for the convenience of description, only some but not all of the relevant portions of the present application are shown in the drawings. Before discussing exemplary embodiments in more detail, it should be noted that some exemplary embodiments are described as processes or methods depicted as flowcharts.

In addition, the order of the operations may be re-arranged. The process may be terminated when its operations are completed, but may have additional steps not included in the figure. The processes may correspond to methods, functions, procedures, subroutines, and the like.
The first embodiment is as follows:
fig. 1 is a flowchart of a service data management method of an electric power internet of things provided in an embodiment of the present application, where the service data management method of the electric power internet of things provided in this embodiment may be executed by a service data management device of the electric power internet of things, the service data management device of the electric power internet of things may be implemented in a software and/or hardware manner, and the service data management device of the electric power internet of things may be formed by two or more physical entities or may be formed by one physical entity. Generally, the service data management device of the power internet of things can be a power internet of things system.
The following description will be given by taking a service data management device of an electric power internet of things as an example of a main body for executing a service data management method of the electric power internet of things. Referring to fig. 1, the service data management method of the power internet of things specifically includes:
s110, the smart meter determines the storage attribute of the service data based on the data type of the current service data, wherein the storage attribute comprises a public attribute and a private attribute.
The business data management method of the power internet of things aims to select the corresponding business data storage mode according to the data type of the business data, so that the safety of business data storage and extraction is improved adaptively, the efficiency of data extraction is guaranteed, and the operation of the power internet of things is optimized.
Specifically, referring to fig. 2, in the electric power internet of things system, each smart meter 11 is in signal connection with a public node 12 and a private node 13, respectively, and is used for storing service data of the smart meter 11. The public nodes 12 and the private nodes 13 are provided in a plurality, and when the smart meter 11 stores the service data, the service data is stored to the plurality of public nodes 12 or the plurality of 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 in the public node 12 and the private node 13 to perform processing on related services of the power internet of things. The intelligent electric meter 11 is arranged corresponding to each power consumption unit, and collects and stores relevant service data generated in the household power consumption 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 the service data of the public attribute, and the private node 13 stores the 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 without verifying the identity of the data management node, so that the data management node can rapidly extract related service data for service processing, the processing efficiency of the service data is improved, and the operation of the electric power internet of things system is optimized. The private node 13 verifies the validity of the data management node identity according to the data request of the data management node 14, so as to ensure the security of the data extraction process and avoid the situation that the service data is stolen by an illegal node. And one end of the corresponding data management node performs related service processing according to the extracted service data so as to realize service operation processing of the power Internet of things system.
When the business data are stored, the intelligent electric meter determines the storage attribute of the current business data based on the data type of the business data. The storage attribute identifies the location where the service data needs to be stored. If the storage attribute of the current service data is a public attribute, the service data needs to be stored to a public node; and 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 can be understood that the smart meter generates a lot of service data during the daily operation. The data types of the service data comprise user identity information, a home address, power consumption data, an electric meter 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 power consumption data and the like, is private, and in order to avoid data leakage and data stealing caused by network attack on the part of the service data, the part of the service data needs to be stored in a private node. And for part of service data with lower security requirements, the service data can be directly stored in the 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 part of service data is improved, and the processing efficiency of related services is optimized.
Before that, the data management node pre-constructs a mapping relation between each data type and the corresponding storage attribute, and issues the mapping relation to the intelligent electric meter; correspondingly, when the intelligent electric meter determines the storage attribute of the service data based on the data type of the current service data, the intelligent electric meter queries the mapping relation based on the data type of the service data to determine the storage attribute of the service data. And the data management node manages the storage attribute to which each data type belongs through the mapping relation, and configures the private attribute for each data type if the security requirement is high and the data needs to be stored in the private node according to the actual storage requirement of the service data of each data type. On the contrary, if the requirement on the safety of the data type service data 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 the public node, and then the public attribute is configured for the data type.
In one embodiment, the data management node modifies the corresponding mapping relation according to a real-time service data storage requirement, and updates the corresponding mapping relation 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 the private attribute to the 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, thereby completing the modification of the storage attribute of the service data of the corresponding data type. Furthermore, 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 migrated to the storage node, 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 electric meter divides the service data into a plurality of service data packets which are mutually redundant, and the service data packets are stored to each public node or private node in a distributed mode according to the storage attribute of the service data, wherein the service data packets comprise identification information of the intelligent electric meter and timestamp information corresponding to the service data.
Further, after the storage attribute of the service data is determined, the service data can 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 through the public nodes or the private nodes, so that the fault tolerance of service data storage can be improved, the conditions that data are easy to steal and lose due to single node storage are avoided, and the safety of service data storage is guaranteed.
Specifically, the smart meter splits the current service data into a plurality of service data packets, each data packet includes part of service data, and each service data packet further includes mutually redundant part of service data, so as to further improve the fault tolerance of service data storage. It can be understood that, by redundantly backing up part of the service data through each service data packet, even if the service data of one storage node is lost or the storage node is failed, the service data packets of the other storage nodes can be extracted, and the complete service data can be restored through the redundantly backed up service data.
After the intelligent electric meter 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. And the subsequent data management node can conveniently inquire and extract the service data according to the corresponding identification information and the timestamp information.
S130, when the data management node extracts the service data, the data management node sends a data request to each public node or each private node, where the data request includes the identification information and the timestamp information corresponding to the service data;
s140, each public node responds to the data request and returns a corresponding service data packet to the data management node, or each private node responds to the data request and performs consensus verification on the identity of the data management node, whether the identity of the data management node is legal is judged, and if the identity of the data management node is legal, 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, the data management node sends a data request to the corresponding storage node. And the data management node determines the storage attribute of the service data to be requested by inquiring the mapping relation, and further sends a data request to the corresponding public node or private node. Correspondingly, the data request comprises timestamp information of service data to be requested and identification information corresponding to the intelligent electric meter, so that the storage node returns a corresponding service data packet based on the timestamp information and the identification information.
Further, after each public node or each private node receives the data request, a 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 authentication means in order to improve the efficiency of data extraction processing, when the public node responds to the data request, the public node directly queries the service data packet stored inside according to the timestamp information and the identification information, and returns the service data packet to the data management node.
And for the corresponding private node, in order to guarantee the security of data storage and extraction, the identity of the data management node needs to be verified when the data request is responded. Referring to fig. 3, the step of performing consensus verification on the identity of the data management node by each private 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 prestored verification information, generates a first identity verification result, and summarizes the first identity verification result to a designated consensus node, wherein 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;
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 based on the consensus verification result.
The embodiment of the application adopts a block chain-based consensus verification mode to carry out identity verification on the data management node. Before that, the legal data management node stores the authentication information of the identity of the legal data management node in each private node in advance for subsequent identity authentication of the private node. When the data request of the data management node is responded, the private node compares the verification information provided by the data management node in real time based on the verification information stored by the private node, and the verification information can be sent to the private node together with the data request. And judging whether the two are consistent according to the verification information comparison result, and further outputting a corresponding first identity verification result. Considering that a single private node has network attack and manipulation influences, the embodiment of the present application does not directly use the authentication result of the single private node as the final authentication result. But performs consensus verification based on the first authentication results of the private nodes to determine a final authentication result. The method comprises the steps that a private node is selected from all the private nodes to serve as a consensus node, and the consensus node summarizes first identity verification results of all the private nodes to conduct consensus verification. And the common identification verification adopts a few majority-obeying modes, and if the first identity verification result judges that the identity of the current data management node is legal to exceed 50%, the identity of the data management node is determined to be legal. Otherwise, the current data management node is considered to be illegal, the data request is ignored, and no data request response is carried out on the data request. 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 as to complete the response of the data request.
In one embodiment, the data management node periodically updates the verification information of itself and updates the verification information to each private node. It can be understood that, in order to avoid that the verification information is cracked and forged, and thus the illegal node easily acquires the service data stored by the private node, in the embodiment of the application, the verification information of the data management node is periodically updated, and the verification information is updated to each private node, so that the difficulty of stealing the service data is increased, the security of data storage and extraction is improved, and the operation of the power internet of things is optimized.
