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 configuration data management method based on attribute classification according to an embodiment of the present application, where the configuration data management method based on attribute classification provided in this embodiment may be executed by a configuration data management device based on attribute classification, the configuration data management device based on attribute classification may be implemented in a software and/or hardware manner, and the configuration data management device based on attribute classification may be formed by two or more physical entities or may be formed by one physical entity. In general, the attribute-classification-based configuration data management device may be an electric power internet of things system.
The following description will be given taking the attribute-classification-based configuration data management apparatus as an example of a main body that performs the attribute-classification-based configuration data management method. Referring to fig. 1, the method for managing configuration data based on attribute classification specifically includes:
s110, the intelligent electric meter divides configuration data into common data and independent data based on predefined data attribute classification, the common data are packaged into common data packets and sent to common nodes, the independent data are divided into a plurality of independent data packets and stored to the independent nodes in a distributed mode, the configuration data contained in the common data are the same as the configuration data of an associated electric meter of the intelligent electric meter, and the independent data contain the unique configuration data of the intelligent electric meter.
The configuration data management method based on attribute classification aims to safely backup configuration data of an intelligent electric meter and extract corresponding configuration data from a common node and an independent node to configure operation parameters of a new electric meter when the intelligent electric meter is replaced, so that efficient configuration of the operation parameters is achieved, and a good configuration data management effect is achieved. In addition, the configuration data are divided into the common data packet and the independent data packets and backed up on the common nodes and the plurality of independent nodes, so that the storage pressure of the data management server can be reduced, the storage space of the configuration data is saved, and the operation of the power internet of things is optimized.
Specifically, referring to fig. 2, in the electric power internet of things system, the smart meter 11 is in signal connection with the common node 12, the plurality of independent nodes 13, the designated third party 14 and the data management server 15, and correspondingly, the data management server 15 is in signal connection with the smart meter 11, the common node 12, the plurality of independent nodes 13 and the designated third party 14. The smart meter 11 is arranged corresponding to each electricity consumption unit and is used for processing services such as electricity metering, safety detection and log generation. The common node 12 is used for backing up common data of each intelligent electric meter 11, and the independent node 13 is used for backing up independent data of each intelligent electric meter 11, so that backup storage of configuration data of the intelligent electric meters is achieved, and the configuration data is prevented from being lost to influence service operation. The data management server 15 is configured to collectively manage the services of the intelligent electric meters 11, and issue the configuration data to the intelligent electric meters 11 to configure the operation parameters by setting the configuration data of the intelligent electric meters 11, so as to implement service operation management of the intelligent electric meters 11. The designated third party 14 is a trusted third party key management server for generating key pairs corresponding to the configuration data for subsequent independent packet encryption storage and decryption. And the appointed third party generates the key pair based on the identification of the intelligent electric meter, sends the key pair to the intelligent electric meter, and sends the decryption key of the key pair to the data management server based on the identification. It can be understood that, by generating a corresponding key pair corresponding to each smart meter, the smart meter can perform encrypted storage of the independent data packet. And a decryption key corresponding to the data management server is provided, so that the subsequent data management server can decrypt the independent data packet conveniently. Thereby, the safe storage of the independent data packet can be further ensured. The independent data packets are encrypted for storage, so that the difficulty of stealing the independent data packets can be increased, and the safety of storage and extraction of the independent data packets is further improved. In addition, the key pair for encrypting the independent data packet is managed by the trusted appointed third party, so that the key management process of the data management server can be saved, the service processing burden of the data management server is reduced, and the service processing efficiency is optimized.
Further, based on the power internet of things architecture, after the data management server issues the configuration data to the smart meter, the smart meter sets the operation parameters of the smart meter based on the configuration data, and processes the related services based on the operation parameters. After the operation parameter configuration is completed, the intelligent electric meter divides the configuration data into common data and independent data based on predefined data attribute classification, directly packs the common data into a common data packet, and divides the independent data into a plurality of independent data packets. It should be noted that, in the embodiment of the present application, the configuration data is split into the common data and the independent data according to the common attribute and the independent attribute of the configuration data, and the common data packet and the independent data packet are backed up respectively. The configuration data contained in the common data packet is the same as other associated electric meters in the electric power Internet of things system. Generally speaking, when an electric power internet of things system is set, corresponding to each intelligent electric meter in an area, configuration data of electric quantity collection, safety detection and work log generation services are the same, the part of the intelligent electric meters are defined as related electric meters, and when the configuration data of the intelligent electric meters are split, the common configuration data of the part of the intelligent electric meters are split into common data. The configuration data such as the identity of the intelligent electric meter, the session key of data transmission, the electric meter number information and the like have independent attributes, and the part of the configuration data is different in each intelligent electric meter, so that the part of the configuration data is split into the independent data when the configuration data is split. Based on the configuration data characteristics, data attribute classification of each part of configuration data is predefined, so that a subsequent intelligent electric meter can divide the configuration data into common data and independent data based on the data attribute classification. After the data splitting is completed, the intelligent electric meter splits the independent data into a plurality of independent data packets, encrypts each independent data packet by using an encryption key pre-configured by a designated third party, stores each independent data packet to a plurality of independent nodes in a distributed manner, reserves a decryption key corresponding to the encryption key, and configures the decryption key for the data management server in advance by the designated third party. And for the shared data, the shared data is directly packaged into a shared data packet and stored in the shared node. It can be understood that the independent data packet contains configuration data such as the identification of the intelligent electric meter, the session key of data transmission, the electric meter number information and the like, the data is relatively private, and once the data is leaked, risks such as leakage and tampering of the electricity utilization data exist. Therefore, the embodiment of the application ensures the storage safety of the independent data packets by encrypting the independent data packets. In addition, it should be noted that in the embodiment of the application, the plurality of independent nodes are adopted to respectively store the independent data packets, and the independent data is divided into the plurality of parts for storage, so that the situation that the user private data is easily stolen due to data concentration can be avoided, and the security of data storage is further ensured.
In one embodiment, when a plurality of independent data packets are generated from independent data, each of the independent data packets corresponding to the independent data includes the configuration data that is redundant with each other. It can be understood that the fault tolerance and the safety of the independent data storage can be further improved by mutually redundantly backing up partial configuration data among the independent data packets. When the independent data packet stored in one independent node is lost, complete independent data can be obtained by restoring partial configuration data of redundant backup of other independent nodes, so that the fault tolerance request of the configuration data backup is improved, and the integrity of the data is guaranteed.
In one embodiment, the designated third party generates a new key pair every other key management period, and updates the key pair of the smart meter and the decryption key of the data management server based on the new key pair. It can be understood that, by periodically updating the encryption key and the decryption key, the situation that the encryption key and the decryption key are easily broken, which causes the independent data packet to be stolen and leaked can be avoided. Therefore, the difficulty of stealing the independent data packet is increased, the safety of data storage and extraction is improved, and the operation of the power internet of things is optimized.
S120, each independent node receives and stores the corresponding independent data packet, the shared node inquires a storage list based on the received shared data packet and judges whether the shared data packet is stored in advance, if yes, the received shared data packet is discarded, and if not, the shared data packet is stored.
Further, after the shared node and the independent nodes receive the independent data packets and the shared data packets, each independent node directly stores the independent data packets, and the shared node judges whether the shared data packets are backed up in advance. It can be understood that the associated meters of the smart meters all include configuration data of the common data packet, and when the smart meters back up and store the common data packet, there may be a case that the associated meters back up and store the common data packet in advance. In consideration of the fact that the same common data packets are repeatedly backed up and occupy the storage space of the common node, in the embodiment of the application, when the common data packets are stored, the storage list is inquired and records each common data packet stored by the common node. If the shared node is determined to store the shared data packet in advance, deleting the currently received shared data packet. And if the common node is determined not to store the common data packet, storing and backing up the currently received common data packet.
S130, the intelligent electric meter generates data labels based on the storage positions of the common data packets and the independent data packets, binds the data labels with the identity of the intelligent electric meter to generate configuration records and sends the configuration records to a data management server, and the data management server stores the configuration records in a configuration record table.
Further, after storing each of the independent data packets and the common data packet, the smart meter generates a data tag corresponding to the storage locations of the independent data packet and the common data packet, where the data tag identifies the storage locations of the independent data packet and the common data packet, and the smart meter can extract the corresponding independent data packet and the corresponding common data packet from the independent node and the common node based on the data tag as a data index.
Further, after the common data packets and the independent data packets are stored in the common nodes and the independent nodes, the intelligent electric meter also binds the data labels with the identity of the intelligent electric meter to generate a configuration record, and the configuration record is sent to the data management server and stored in the configuration record table. The configuration records mark backup records of the configuration data of the intelligent electric meters, and the backup records can facilitate the data management server to obtain the common data packets and the independent data packets of the backup of each intelligent electric meter so as to reconfigure the configuration data.
In one embodiment, when the smart meter detects that the corresponding configuration data is updated, the smart meter generates a new common data packet and/or an independent data packet based on the updated configuration data, and updates the common data packet and/or the independent data packet to the common node and/or the independent node according to the data tag. It can be understood that, in order to ensure real-time update of configuration data backup and avoid the situation that the use of subsequent configuration data is affected due to the fact that the version of the backed-up configuration data is lagged, in the embodiment of the present application, after the configuration data is updated to the smart meter by the data management server, the relevant operating parameters are reset based on the new configuration data, and then the update of the common data packet and/or the independent data packet at the common node and/or the independent node is performed based on the updated configuration data (which part of the configuration data needs to be updated, the corresponding data packet is sent to the corresponding node). When updating the independent packet, the updated independent packet is encrypted using the encryption key with reference to the storage method of the independent packet, thereby generating a new independent packet. And then, when the new common data packet and/or the independent data packet are updated to the common node and/or the independent node, the data label is attached to the common data packet and/or the independent data packet, the common node and/or the independent node inquires internal storage according to the data label, deletes the corresponding common data packet and/or the independent data packet, and correspondingly stores the new common data packet and/or the independent data packet, so that the backup updating of the configuration data is completed, and the real-time performance of the configuration data backup is guaranteed.
In one embodiment, when the smart meter is influenced by an operation fault and the like, and an operation parameter is lost, the operation parameter is reconfigured. Referring to fig. 3, the operation parameter reconfiguration process includes:
s131, when the smart electric meter detects that the self operation parameters are lost, extracting the corresponding common data packets and/or the independent data packets from the common nodes and/or the independent nodes based on the data labels;
s132, acquiring the corresponding configuration data based on the common data packet and/or the independent data packet, and configuring the self-operation parameters based on the corresponding configuration data.
Specifically, after the operating parameter is lost, the smart meter requests the common node and/or the independent node for the corresponding common data packet and/or the independent data packet based on the data tag (which part of the parameter is lost, then requests the corresponding node for the corresponding configuration data). And the common node and/or the independent node inquires internal storage according to the data label, extracts the corresponding common data packet and/or independent data packet, and returns the common data packet and/or independent data packet to the intelligent electric meter. If the returned data packet comprises the independent data packet, the intelligent electric meter decrypts the independent data packet through the decryption key of the pre-configuration key pair to obtain the configuration data. And the configuration data can be directly extracted from the common data packet. The lost operation parameters are reconfigured based on the configuration data, so that the reconfiguration of the operation parameters is completed, and the operation of the power internet of things is prevented from being influenced by the loss of the operation parameters.
It should be noted that, in the embodiment of the present application, the independent data packet is encrypted and stored in the independent node, and the independent node is only used for the storage management of the independent data packet and cannot obtain the substantial content of the independent data packet, so that the risk of leakage of related private data can be reduced, and the security of backup storage of the independent data packet is improved.
In one embodiment, after the internal system of the smart meter is upgraded, since the system upgrade deletes all the operating parameters of the smart meter, the smart meter queries and extracts the corresponding configuration record by querying the configuration record table of the data management server and using the identity of the smart meter as a data index. And extracting corresponding data labels based on the configuration record, sending the data labels to the common nodes and the independent nodes to extract the common data packets and the independent data packets which are backed up in advance, decrypting the independent data packets by using a decryption key of the pre-configuration key pair to further obtain corresponding configuration data, and performing operation parameter configuration again. Thus, the operation parameter configuration of the intelligent electric meter after the system is upgraded is completed.
S140, when the data management server detects that a new electric meter replaces the intelligent electric meter to access the network, the configuration record table is inquired based on the identity identification corresponding to the intelligent electric meter, the corresponding configuration record is extracted, the data label of the configuration record is obtained, the corresponding independent data packet and the common data packet are extracted from each independent node and each common node according to the data label, the configuration data is formed based on the common data packet and each independent data packet, and the configuration data is sent to the new electric meter to configure the operation parameters.
Furthermore, in the operation process of the electric power internet of things system, the situation that the intelligent electric meter needs to be replaced due to equipment failure and equipment aging sometimes occurs. And when the new electric meter replaces the original intelligent electric meter to access the network, the operation parameter configuration needs to be carried out on the new electric meter. It can be understood that, because the new electric meter is connected to the network in place of the original smart electric meter, and the operation parameters of the new electric meter should be the same as those of the original smart electric meter, the operation parameter configuration of the new electric meter is performed by acquiring the configuration data of the original smart electric meter in the embodiment of the application.

s1402, each independent node and the common node receive the data request, the verification information prestored in the data management server is compared based on the verification information of the data request, whether the identity of the data management server is legal or not is judged, and if yes, the corresponding common data packet and the independent data packet are extracted based on the data label of the data request and returned to the data management server.
Specifically, the data management server requests the shared node and each independent node for a shared data packet and an independent data packet through a data request, wherein the data request comprises a data label of the original intelligent electric meter and verification information of the data management server. And the data labels are used as data indexes to inquire the corresponding common data packets and independent data packets. The verification information is used for comparing with the verification information of the data management server prestored in the common node and each independent node, and judging whether the identity of the current data management server is legal or not. It is understood that the common node and each independent node may respond to the data request only if the authentication is legitimate, and may not respond to the data request otherwise. And finally, after the common node and each independent node determine that the data management server is legal through verification information comparison, extracting the common data packet and the independent data packet which are stored in the corresponding storage positions on the basis of the data label, and returning the common data packet and the independent data packet to the data management server.
Further, based on the obtained common data packet and the independent data packet, the data management server decrypts the independent data packet by using a pre-configured decryption key, further analyzes the common data packet and the common data packet to obtain common data and independent data, synthesizes the common data and the independent data to obtain configuration data of the original intelligent electric meter, and sends the configuration data to a new electric meter to configure operation parameters. In addition, the data management server also sends the data labels of the original intelligent electric meters to the new electric meters together, so that when the new electric meters are upgraded, updated in configuration data or lost in operation parameters, the common data packets and the independent data packets are extracted or updated from the common nodes and the independent nodes based on the data labels.
In one embodiment, when the independent nodes perform verification information comparison, verification information comparison may be performed based on a consensus mechanism of the blockchain. And selecting one node from each independent node as a consensus node, and comparing the verification information of each independent node to obtain a first verification result, wherein the first verification result represents the identity verification result of each independent node. Further, the consensus node summarizes each first verification result, and determines a final identity verification result through a consensus verification mechanism. And the common identification verification adopts a few majority-obeying mode, and if the first verification result judges that the identity of the current independent node is legal to exceed 50%, the identity of the data management server is determined to be legal. Otherwise, the current data management server is considered to be illegal, the data request is ignored, and no data request response is carried out on the data request. After the data management server is verified to be legal, the consensus node informs each independent node to inquire and extract a corresponding independent data packet according to the data label in the data request and sends the independent data packet to the data management server so as to complete the response of the data request.
In one embodiment, the data management server updates the pre-stored authentication information of the individual nodes and the common node every other information management period. By periodically updating the verification information, illegal nodes can be prevented from easily cracking and forging the verification information to obtain related configuration data, and the storage safety of the common data packet and the independent data packets is further ensured.
In an embodiment, the data management server obtains the identity of the new electric meter, and updates the corresponding configuration record on the configuration record table based on the identity of the new electric meter and the identity of the smart electric meter.
