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 power internet of things configuration data backup method based on multiple storage nodes according to an embodiment of the present disclosure, where the power internet of things configuration data backup method based on multiple storage nodes provided in this embodiment may be executed by a power internet of things configuration data backup device based on multiple storage nodes, the power internet of things configuration data backup device based on multiple storage nodes may be implemented in a software and/or hardware manner, and the power internet of things configuration data backup device based on multiple storage nodes may be formed by two or more physical entities or may be formed by one physical entity. Generally, the multi-storage node-based power internet of things configuration data backup device can be a power internet of things system.
The following description will be given by taking the multi-storage-node-based power internet of things configuration data backup device as an example of a main body for executing a multi-storage-node-based power internet of things configuration data backup method. Referring to fig. 1, the power internet of things configuration data backup method based on multiple storage nodes specifically includes:
s110, after configuring self operation parameters according to configuration data issued by a data management server, an intelligent electric meter splits the configuration data into a plurality of configuration data packets, encrypts the configuration data packets by using an encryption key of a pre-configuration key pair, adds a unique data tag to the configuration data packets, and stores each configuration data packet to a plurality of storage nodes in a distributed manner, wherein the key pair comprises the encryption key and a corresponding decryption key.
The electric power internet of things configuration data backup method based on the multiple storage nodes aims at carrying out safe backup on configuration data of an intelligent electric meter, and extracting corresponding configuration data packets from the storage nodes to carry out operation parameter configuration on a new electric meter when the intelligent electric meter is replaced, so that efficient configuration of operation parameters is achieved, and a good configuration data management effect is achieved. Moreover, the configuration data is split into a plurality of configuration data packets and is backed up in a distributed manner on a plurality of storage nodes, so that the security and fault tolerance of the backup of the configuration data can be improved, and the situations that the configuration data is lost and completely stolen due to the fact that a single storage node is attacked by a network are avoided. In addition, through setting up storage node, can also reduce the storage pressure of data management server, optimize the operation of electric power thing networking.
Specifically, referring to fig. 2, in the electric power internet of things system, the smart meter 11 is in signal connection with the plurality of storage nodes 12, the data management server 13 and the designated third party 14, respectively, and correspondingly, the data management server 13 is in signal connection with the plurality of storage nodes 12, the smart meter 11 and the designated third party 14, respectively. 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 storage node 12 is configured to backup configuration data of each smart meter 11, so as to avoid that the configuration data is lost to influence service operation. The data management server 13 is configured to collectively manage the services of the intelligent electric meters 11, and by setting the configuration data of each intelligent electric meter 11, the configuration data is issued to each intelligent electric meter 11 to configure the operation parameters, so that the service operation management of each intelligent electric meter 11 can be realized. The third party 14 is designated as a trusted third party key management server for generating key pairs corresponding to the configuration data for subsequent encrypted storage and decryption of the configuration data. 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 performs encrypted storage of the configuration data. And a decryption key corresponding to the data management server is provided, so that the subsequent data management server can decrypt the configuration data packet conveniently. Thereby, secure storage of configuration data may be ensured. The configuration data is encrypted for storage, so that the difficulty of stealing the configuration data can be increased, and the safety of storage and extraction of the configuration data is further improved. In addition, the key pair for encrypting the configuration data 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 splits the configuration data into a plurality of configuration data packets, and encrypts the configuration data packets by using an encryption key of a designated third-party pre-configuration key pair. In addition, in order to facilitate extraction of the configuration data packets, a unique data tag is added corresponding to each configuration data packet, each configuration data packet is stored in each storage node in a distributed mode, and then query extraction of the data packets can be performed at each storage node according to the data tags.
In one embodiment, the smart meter obtains storage states of all storage nodes, and selects a corresponding number of the storage nodes to store each configuration data packet in a distributed manner based on a storage balancing principle. The storage states of the storage nodes are different, according to actual data storage requirements, a large number of storage nodes can be set in the power internet of things, and in order to avoid the situation that a large number of data packets are split to configure data, and subsequent decryption of the configured data packets and a long data merging and restoring process are caused, the storage states of all the storage nodes are obtained, the intelligent electric meter can ascertain the specific situation of the storage space of each storage node, and select a plurality of storage nodes with idle storage spaces to store the configured data packets according to a storage balancing principle, so that the storage of the configured data packets can be guaranteed to be more balanced, the situation that a large number of configured data packets stored by a single storage node cause internal memory tension is avoided, and the storage management of the configured data is optimized. It should be noted that, because the smart meter selects a plurality of storage nodes from all the storage nodes to store the configuration data packet, in order to facilitate the subsequent smart meter and the data management server to determine the storage node for storing the configuration data packet, the smart meter needs to generate a node record table according to the storage node in which the configuration data packet is stored, and send the node record table to the data management server, so that the subsequent smart meter and the data management server request the configuration data packet from the corresponding storage node according to the node record table. If the storage nodes for storing the configuration data packets are all the storage nodes in the power internet of things, node recording is not needed, and the subsequent intelligent electric meter or the data management server directly requests all the nodes for configuration data packets.
In one embodiment, when the smart meter splits the configuration data, the smart meter further splits the configuration data into a plurality of mutually redundant configuration data packets. It can be understood that there are configuration data of mutually redundant parts between the configuration data packets, so that the fault tolerance of the configuration data storage can be further improved. When the configuration data packet stored in one storage node is lost, the complete configuration data can be obtained by restoring the redundant backup configuration data packets stored in the other storage nodes.
In one embodiment, when the smart meter detects that the configuration data is updated, a new configuration data packet is generated based on the updated configuration data and is updated to the corresponding storage node according to the data tag. It can be understood that, in order to ensure real-time update of the 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 data management server updates the configuration data to the smart meter, the relevant operation parameters are reset based on the new configuration data, and then the configuration data packet at the storage node is updated based on the updated configuration data. And generating a new configuration data packet by encrypting the updated configuration data by using an encryption key according to the storage mode of the configuration data packet, and adding a data tag to the new configuration data packet, wherein the data tag is the same as the data tag of the original configuration data packet. Therefore, when the new configuration data packet is updated to the storage node, the storage node queries internal storage according to the data tag, deletes the original configuration data packet containing the same data tag, and correspondingly stores the new configuration data packet, so that the backup updating of the configuration data is completed, and the real-time performance of the backup of the configuration 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 configuration data is stolen and leaked due to the fact that the encryption key and the decryption key are easily cracked can be avoided. Therefore, the difficulty of stealing configuration data is increased, the safety of data storage and extraction is improved, and the operation of the power internet of things is optimized.
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:
s111, when the smart electric meter detects that the self operation parameters are lost, extracting the corresponding configuration data packets from each storage node based on the data labels;
s112, decrypting each configuration data packet by using the decryption key to obtain the configuration data, and configuring the self operation parameters based on the configuration data.
Specifically, after the operating parameter is lost, the smart meter requests the corresponding configuration data packet from the corresponding storage node based on the data tag. And the storage node inquires internal storage according to the data label, extracts a configuration data packet containing the same data label and returns the configuration data packet to the intelligent electric meter. The intelligent electric meter can obtain corresponding configuration data by decrypting the configuration data packet through the decryption key of the pre-configuration key pair, and the lost operation parameters are reconfigured based on the configuration data, so that the reconfiguration of the operation parameters is completed, and the phenomenon that the operation parameters are lost to influence the operation of the power internet of things is avoided.
It should be noted that, in the embodiment of the present application, the configuration data is encrypted into the configuration data packet and is stored in each storage node in a distributed manner, and the storage node is only used for the storage management of the configuration data packet and cannot acquire the substantial content of the configuration data packet, so that the risk of configuration data leakage can be reduced, and the security of the backup storage of the configuration data is improved.
S120, the intelligent electric meter binds the data label with the identity of the intelligent electric meter to generate a configuration record and sends the configuration record to a data management server, and the data management server stores the configuration record in a configuration record table.
Further, after the configuration data packets are stored in each storage node in a distributed manner, the smart electric meter also binds the data tag with the identity of the smart electric meter to generate a configuration record, and sends the configuration record to the data management server and stores the configuration record in the configuration record table. The configuration records indicate backup records of the configuration data of the intelligent electric meters, and the backup records can facilitate the data management server to acquire configuration data packets backed up by each intelligent electric meter so as to reconfigure the configuration data.
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. Extracting corresponding data labels based on the configuration record, sending the data labels to the storage nodes to extract the configuration data packets backed up in advance, decrypting the configuration data packets through the decryption keys of the pre-configuration key pairs to obtain 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.
S130, when detecting that a new electric meter replaces the intelligent electric meter to access the network, the data management server inquires the configuration record table based on the identity corresponding to the intelligent electric meter, extracts the corresponding configuration record, acquires the data label of the configuration record, extracts the corresponding configuration data packet from each storage node according to the data label, decrypts the configuration data packet based on the pre-configured decryption key to obtain the configuration data, and sends the configuration data to the new electric meter for operating parameter configuration.
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.
Specifically, when the data management server detects that the new electric meter replaces the original intelligent electric meter to access the network. Firstly, inquiring a configuration record table through the identity of the original intelligent electric meter to determine the configuration record of the original intelligent electric meter. And requesting to extract the configuration data packet of the original intelligent electric meter from each storage node based on the data label of the configuration record. Referring to fig. 4, the configuration packet extraction process includes:
s1301, the data management server sends data requests to the storage nodes, wherein the data requests comprise the data labels and verification information of the data management server;
s1302, each storage node receives the data request, compares the verification information of the data request with the verification information prestored in the data management server to generate a first verification result, and summarizes the first verification result to a designated consensus node, wherein the consensus node is selected from a plurality of storage nodes in advance;
and S1303, the common identification nodes judge whether the identity of the data management server is legal, and if so, each storage node extracts the corresponding configuration data packet based on the data tag of the data request and returns the configuration data packet to the data management server.
Specifically, the data management server requests each storage node to configure a data packet through a data request, where the data request includes a data tag of the original smart meter and verification information of the data management server. And the data tag is used as a data index to inquire a corresponding configuration data packet. The verification information is used for comparing with the verification information of the data management server prestored in the storage node, and judging whether the identity of the current data management server is legal or not. It is understood that the storage node side responds to the data request only if the authentication is legitimate, and does not respond to the data request otherwise. And when the identity is verified, each storage node adopts a formula verification mechanism based on the block chain to judge whether the identity of the data management server is legal or not. Each storage node firstly compares the verification information of the data request according to the pre-stored data management server to generate a first verification result, wherein the first verification result represents whether the verification information is consistent and whether the identity is legal. Further, the first verification result of each storage node is collected to the common node. And the consensus node determines a final identity authentication result through a consensus authentication 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 storage 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 storage node to inquire and extract a corresponding configuration data packet according to the data tag in the data request and sends the configuration data packet to the data management server so as to complete the response of the data request.
Further, based on each acquired configuration data packet, the data management server decrypts the configuration data by using a preconfigured decryption key to obtain each part of configuration data of the original intelligent electric meter, combines the part of configuration data to obtain complete configuration data, and issues the configuration data to the new electric meter for operation parameter configuration. 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 the new electric meters can extract or update the configuration data packet from the storage node based on the data labels when the system is upgraded, the configuration data is updated or the operation parameters are lost. In one embodiment, if the configuration data packets are stored in a mutually redundant backup manner, the data management server further removes the mutually redundant data and synthesizes the configuration data after decrypting the configuration data packets based on the preconfigured decryption key.
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.
