Embodiment one:
fig. 1 shows a flowchart of a configuration data backup method of an electric power internet of things provided in an embodiment of the present application, where the configuration data backup method of the electric power internet of things provided in the embodiment may be executed by a configuration data backup device of the electric power internet of things, the configuration data backup device of the electric power internet of things may be implemented by software and/or hardware, and the configuration data backup 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 configuration data backup device of the electric power internet of things may be an electric power internet of things system.
The following describes an example in which the configuration data backup device of the electric power internet of things is taken as a main body for executing the configuration data backup method of the electric power internet of things. Referring to fig. 1, the configuration data backup method of the electric power internet of things specifically includes:
s110, after the current intelligent electric meter configures operation parameters according to configuration data issued by a data management server, splitting the configuration data into a common data packet and an independent data packet, and sending the common data packet and the independent data packet to a storage node, wherein the configuration data contained in the common data packet is identical to the associated electric meter of the intelligent electric meter, and the independent data packet contains the configuration data unique to the intelligent electric meter;
S120, the storage node stores the independent data packet, queries a storage list based on the shared data packet, judges whether the shared data packet is stored in advance, discards the received shared data packet if yes, and stores the shared data packet if no;
and S130, the storage node generates a data tag based on the storage positions of the shared data packet and the independent data packet, and returns the data tag to the intelligent ammeter.
The configuration data backup method of the electric power Internet of things aims at carrying out safe backup on configuration data of the intelligent electric meter, and extracting corresponding configuration data packets from the storage node to carry out operation parameter configuration on the novel electric meter when the intelligent electric meter is replaced, so that efficient configuration of operation parameters is realized, and a better configuration data management effect is realized. And the configuration data is divided into a shared data packet and an independent data packet and backed up in the storage node, 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 electric power Internet of things is optimized.
Specifically, referring to fig. 2, in the power internet of things system, the smart meter 11 is in signal connection with the storage node 12, the data management server 13, and the designated third party 14, respectively, and the data management server 13 is in signal connection with the storage node 12, the smart meter 11, and the designated third party 14, respectively. The smart meter 11 is set corresponding to each electricity utilization unit, and is used for processing services such as electricity metering, safety detection, log generation and the like. The storage node 12 is configured to backup configuration data of each smart meter 11, so as to avoid that the service operation is affected by loss of the configuration data. The data management server 13 is configured to overall manage the service of each smart meter 11, and by setting configuration data of each smart meter 11, send the configuration data to each smart meter 11 to perform operation parameter configuration, so as to implement service operation management of each smart meter 11. The designated third party 14 is a trusted third party key management server for generating key pairs corresponding to configuration data for subsequent independent packet encryption storage and decryption. And the appointed third party generates the key pair based on the identity of the intelligent ammeter, sends the key pair to the intelligent ammeter, and sends the decryption key of the key pair to the data management server based on the identity. It can be understood that the smart meter can be used for encrypting and storing the independent data packet by generating a corresponding key pair corresponding to each smart meter. And provides the corresponding decryption key of the data management server, so that the subsequent data management server can decrypt the independent data packet. Therefore, the safe storage of the independent data packet can be further ensured. The independent data packet is stored by encryption, so that the difficulty of stealing the independent data packet can be increased, and the security of storing and extracting the independent data packet is further improved. In addition, the embodiment of the application manages the key pair of the encrypted independent data packet through the trusted appointed third party, so that the key management flow 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 further optimized.
Further, based on the above-mentioned electric power internet of things architecture, after the data management server issues the configuration data to the smart electric meter, the smart electric meter sets its own operation parameters based on the configuration data, and processes related services based on the operation parameters. After the operation parameter configuration is completed, the intelligent ammeter splits the configuration data into a common data packet and an independent data packet. It should be noted that, in the embodiment of the present application, the configuration data is split into a common data packet and an independent data packet 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 ammeter in the electric power internet of things system. In general, when the electric power internet of things system is set, the configuration data of the electric power collection, the safety detection and the work log generation service of each intelligent electric meter corresponding to one area are the same, the intelligent electric meters are defined as associated electric meters, and when the configuration data of the intelligent electric meters are split, the configuration data shared by the intelligent electric meters are split into shared data packets. The 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 have independent attributes, and the configuration data are different in all the intelligent electric meters, so that the configuration data are split into independent data packets when the configuration data are split. Further, the smart meter encrypts the independent data packet by using an encryption key of a preset key pair of a designated third party, and sends the shared data packet and the independent data packet to a storage node for storage. Before that, the smart meter encrypts the independent data packet using an encryption key of a pre-configured key pair, sends the common data packet and the independent data packet to a storage node, and sends a decryption key of the key pair to the data management server. It can be understood that the independent data packet contains configuration data such as an identity identifier of the smart electric meter, a session key of data transmission, electric meter number information and the like, the data is private, and once the data is leaked, risks such as leakage of electricity consumption data, tampering and the like exist. Therefore, the embodiment of the application ensures the safety of storing the independent data packet by encrypting the independent data packet.
Further, after receiving the independent data packet and the shared data packet, the storage node directly stores the independent data packet first, and judges whether the shared data packet is backed up in advance. It can be understood that, the associated electric meters of the smart electric meters all contain configuration data of the shared data packet, and when the smart electric meters backup and store the shared data packet, there may be a case that the associated electric meters backup and store the shared data packet in advance. In consideration of that the same shared data packet is repeatedly backed up, the storage space of the storage node is occupied, so that when the shared data packet is stored, the embodiment of the application records each shared data packet and independent data packet stored by the storage node by querying a storage list. At this time, if it is determined that the storage node has previously stored the common packet, the currently received common packet is deleted. And if the storage node is determined not to store the shared data packet, carrying out storage backup on the currently received shared data packet.
Further, after storing the independent data packet and the common data packet, the storage node generates a data tag corresponding to the storage positions of the independent data packet and the common data packet, the data tag identifies the storage positions of the independent data packet and the common data packet, and the data tag is sent to the smart meter, so that the smart meter can extract the corresponding independent data packet and the common data packet from the storage node based on the data tag as a data index.
In one embodiment, when the smart meter detects that the corresponding configuration data is updated, a new common data packet and/or the independent data packet is generated based on the updated configuration data, and the data packet is updated to the storage node according to the data tag. It can be understood that, in order to ensure real-time update of configuration data backup, and avoid that the backup configuration data version is behind to affect use of subsequent configuration data, in the embodiment of the present application, after the data management server updates the configuration data to the smart meter, relevant operation parameters are reset based on the new configuration data, and further, updating of a common data packet and/or an independent data packet at the storage node is performed based on the updated configuration data. When the individual data packet is updated, a new configuration data packet is generated by encrypting the updated individual data packet with an encryption key with reference to the storage method of the individual data packet. And when the new shared data packet and/or the independent data packet is updated to the storage node, attaching the data tag to the shared data packet and/or the independent data packet, inquiring internal storage by the storage node according to the data tag, deleting the corresponding shared data packet and/or the independent data packet, and correspondingly storing the new shared data packet and/or the independent data packet, thereby completing backup update of configuration data and guaranteeing real-time of configuration data backup.
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 appreciated that by periodically updating the encryption key and the decryption key, the situation that the encryption key and the decryption key are easily broken, resulting in that the independent data packet is stolen and revealed can be avoided. Therefore, the difficulty of stealing the independent data packets is increased, the safety of data storage and extraction is improved, and the operation of the electric power Internet of things is optimized.
In one embodiment, when the smart meter is affected by an operation fault or the like and the operation parameter is lost, the operation parameter is reconfigured. Referring to fig. 3, the operation parameter reconfiguration flow includes:
s131, when the intelligent ammeter detects that the self operation parameters are lost, the corresponding common data packet and/or the independent data packet are extracted from the storage node based on the data tag;
s132, acquiring corresponding configuration data based on the common data packet and/or the independent data packet, and configuring self-operation parameters based on the corresponding configuration data.
Specifically, after the operation parameters are lost, the intelligent ammeter requests the corresponding shared data packet and/or independent data packet from the storage node based on the data tag. And the storage node queries internal storage according to the data tag, extracts a corresponding shared data packet and/or independent data packet, and returns the shared data packet and/or independent data packet to the intelligent ammeter. If the returned data packet comprises an independent data packet, the intelligent ammeter decrypts the independent data packet through a decryption key of the preset key pair to obtain configuration data. And the configuration data can be directly extracted for the shared data packet. And reconfiguring the lost operation parameters based on the configuration data, so as to finish the reconfiguration of the operation parameters and avoid the influence of the loss of the operation parameters on the operation of the electric power Internet of things.
It should be noted that, in the embodiment of the present application, the independent data packet is encrypted and stored in the storage node, and the storage node is only used for storing and managing the independent data packet, so that the essential content of the independent data packet cannot be obtained, and therefore, the risk of disclosure of related privacy data can be reduced, and the security of backup storage of the independent data packet is improved.
And S140, the intelligent ammeter binds the data tag with the identity mark of the intelligent ammeter 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.
And S150, when the data management server detects that a new electric meter is connected to the network instead of the intelligent electric meter, inquiring the configuration record table based on the identity mark corresponding to the intelligent electric meter, extracting the corresponding configuration record, acquiring the data tag of the configuration record, extracting the corresponding common data packet and the independent data packet from the storage node according to the data tag, synthesizing the configuration data, and sending the configuration data to the new electric meter for operation parameter configuration.
Furthermore, after the common data packet and the independent data packet are stored in the storage node, the intelligent ammeter also binds the data tag with the identity of the intelligent ammeter 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 record marks the backup record of the configuration data of the intelligent electric meter, and the backup record can facilitate the data management server to acquire the shared data packet and the independent data packet of each intelligent electric meter backup so as to reconfigure the configuration data.
In one embodiment, after the intelligent ammeter performs internal system upgrade, because the system upgrade deletes all its own operating parameters, the intelligent ammeter queries and extracts corresponding configuration records by querying a configuration record table of the data management server and using its own identity as a data index. Based on the configuration record, a corresponding data label is extracted, the data label is sent to a storage node, a shared data packet and an independent data packet which are backed up in advance can be extracted, the independent data packet is decrypted by using a decryption key of a pre-configuration key pair, corresponding configuration data is further obtained, and operation parameter configuration is conducted again. Thus, the operation parameter configuration of the intelligent ammeter after the system upgrade is completed.
Further, in the operation process of the electric power internet of things system, the intelligent electric meter sometimes happens due to equipment failure and equipment aging and needs to be replaced. And when the new electric meter is used for replacing the original intelligent electric meter to access the network, the operation parameters of the new electric meter are required to be configured. It can be understood that, because the new electric meter is used for replacing the original intelligent electric meter to access the network, the operation parameters of the new electric meter are the same as those of the original intelligent electric meter, so that the embodiment of the application performs the operation parameter configuration of the new electric meter by acquiring the configuration data of the original intelligent electric meter.
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, and determining the configuration record of the original intelligent electric meter. And then, the data label based on the configuration record requests the storage node to extract the common data packet and the independent data packet of the original intelligent ammeter. Referring to fig. 4, the configuration packet extraction flow includes:
s1301, the data management server sends a data request to the storage node, wherein the data request comprises the data tag and verification information of the data management server;
s1302, the storage node receives the data request, compares the verification information pre-stored by the data management server based on the verification information of the data request, judges whether the identity of the data management server is legal, and if yes, extracts the corresponding common data packet and the independent data packet based on the data tag of the data request, and returns the data packet to the data management server.
Specifically, the data management server requests the shared data packet and the independent data packet from the storage node through a data request, wherein the data request comprises a data tag of the original intelligent ammeter and verification information of the data management server. The data labels are used as data indexes to inquire corresponding shared data packets and independent data packets. The verification information is used for comparing with the verification information of the data management server pre-stored in the storage node, and judging whether the identity of the current data management server is legal or not. It will be appreciated that the storage node responds to a data request only if the authentication is legal, and does not respond to the data request otherwise. And finally, after the storage node determines that the data management server is legal through verification information comparison, extracting a common data packet and an independent data packet which are stored in corresponding storage positions based on the data label, and returning the common data packet and the independent data packet to the data management server.
Further, based on the obtained shared data packet and the independent data packet, the data management server decrypts the independent data packet by using a pre-configured decryption key, and further obtains configuration data of the original intelligent ammeter based on the independent data packet and the shared data packet, and issues the configuration data to the new ammeter for operation parameter configuration. In addition, the data management server also transmits the data label of the original intelligent ammeter to the new ammeter together, so that when the new ammeter is subjected to system upgrading, configuration data updating or operation parameter loss, the common data packet and the independent data packet are extracted or updated by the storage node based on the data label.
