[0048] In the following description, many specific details are set forth in order to fully understand this application. However, this application can also be implemented in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the connotation of this application. Therefore, this application is not limited by the specific embodiments disclosed below.

[0049] Embodiment 1

[0050] This application provides a blockchain-based energy storage data management method, as Figure 1 shown, including:

[0051] Step 101, obtaining energy storage data to be uploaded to the blockchain;

[0052] In the embodiments of this application, the input energy storage data from the user is received, and then the energy storage data can be further processed such as identification and / or encryption to obtain the energy storage data to be uploaded to the blockchain.

[0053] Optionally, the above-mentioned obtaining of the energy storage data to be uploaded to the blockchain includes:

[0054] Identifying the input energy storage data to determine the data to be encrypted and the data not to be encrypted therefrom;

[0055] Encrypting the above-mentioned data to be encrypted;

[0056] Taking the encrypted above-mentioned data to be encrypted and the above-mentioned data not to be encrypted as the energy storage data to be uploaded to the blockchain.

[0057] In an application scenario, an interface for uploading energy storage data is preset in advance. When the user inputs energy storage data, the corresponding interface can be called to input the corresponding energy storage data or specify an encryption method. For example, an interface as shown in Table 1 can be preset in advance:

[0058] Table 1

[0059]

[0060]

[0061] Users can input corresponding data into the interfaces shown in Table 1 above according to their needs, and the data input from different interfaces will be subject to corresponding data processing.

[0062] In another application scenario, when a user inputs energy storage data, the user can divide each piece of data in the energy storage data to determine the data that needs to be encrypted and the data that does not need to be encrypted in the energy storage data. For example: the energy storage data input by the user includes a first part of data and a second part of data. The user can, according to their own needs, divide the first part of data into data that does not need to be encrypted and attach a corresponding label (such as a label indicating that it does not need to be encrypted), and divide the second part of data into data that needs to be encrypted and attach a corresponding label (such as a label indicating that it needs to be encrypted), so as to subsequently identify and / or encrypt the corresponding data in the energy storage data input by the user to obtain the energy storage data to be uploaded to the chain.

[0063] Furthermore, the above-mentioned label can be manifested as a specific field. Identifying the input energy storage data to determine the data that needs to be encrypted and the data that does not need to be encrypted includes:

[0064] Identifying the target field of the input energy storage data;

[0065] Based on the target field identified in the above-mentioned input energy storage data, determining the data that needs to be encrypted in the above-mentioned input energy storage data.

[0066] Specifically, the data containing the target field can be determined as the data that needs to be encrypted, and the data not containing the target field can be determined as the data that does not need to be encrypted; alternatively, the data containing one type of target field can be determined as the data that needs to be encrypted, and the data containing another type of target field can be determined as the data that does not need to be encrypted.

[0067] Even further, the above-mentioned target field contains more than one category of fields;

[0068] The above-mentioned encrypting of the above-mentioned data that needs to be encrypted includes:

[0069] Based on the above-mentioned more than one category of fields, determining the importance of each part of the data in the above-mentioned data that needs to be encrypted;

[0070] Based on the encryption method corresponding to the importance of each of the above-mentioned parts of the data, encrypting each of the above-mentioned parts of the data separately.

[0071] Specifically, different partial data corresponding to different fields in the target field can be preset, with different degrees of importance; when encrypting each of the above partial data, an encryption algorithm with high complexity can be used to encrypt the partial data whose importance is higher than the preset value, while an encryption algorithm with low complexity can be used to encrypt the partial data whose importance is not higher than the preset value, so that the partial data with importance higher than the preset value after encryption is more difficult to be cracked by outsiders, and the partial data with importance not higher than the preset value after encryption is more convenient for users to decrypt;

[0072] Among them, the above target field can be one or more fields among date, energy storage ID, moment point number, actual active power value of energy storage, upper limit of energy storage charging power, and other types of data, which can be specifically set according to the user's needs. The importance of different fields can also be set according to the user's needs, and no limitations are made here; the above encryption method can be any one of AES encryption algorithm, DES encryption algorithm, and other types of encryption algorithms, and no limitations are made here.

[0073] Optionally, after the above encrypted data to be encrypted and the above non-encrypted data are used as the energy storage data to be uploaded to the blockchain, the above energy storage data management method further includes:

[0074] Compress the above energy storage data to be uploaded to the blockchain to speed up the subsequent process of storing the above energy storage data to be uploaded to the blockchain and save the storage space of the blockchain.

[0075] Specifically, the above compression process of the above energy storage data to be uploaded to the blockchain includes:

[0076] Compress the above energy storage data to be uploaded to the blockchain based on a preset compression algorithm, and then encode the compressed energy storage data to be uploaded to the blockchain based on a preset encoding algorithm. Among them, the above preset compression algorithm is a lossless compression algorithm or other types of compression algorithms, and the above preset encoding algorithm can be a base64 encoding algorithm or other types of encoding algorithms, and no limitations are made here.

[0077] Step 102, store the above energy storage data to be uploaded to the blockchain in the first database of the middleware;

[0078] In the embodiment of the present application, the energy storage data to be uploaded to the blockchain obtained in step 101 is stored in the first database of the middleware, and then the deposit ID returned by the middleware after storing the above energy storage data to be uploaded to the blockchain is obtained and sent to the user. The deposit ID is used for the user to query the corresponding energy storage data to be uploaded to the blockchain in the middleware.

[0079] Step 103, perform an operation to upload the above energy storage data to the blockchain to store the above energy storage data to be uploaded to the blockchain in the blockchain and obtain the corresponding transaction ID;

[0080] In the embodiment of the present application, the energy storage data to be chained obtained in step 101 is chained, that is, the energy storage data to be chained is stored in the blockchain, and the transaction ID returned by the blockchain after storing the energy storage data to be chained is obtained. The transaction ID is data with an identification function unique to each energy storage data to be chained, and the transaction IDs of different energy storage data to be chained are different. In addition, the transaction ID can be data included in the energy storage data to be chained or data generated by the blockchain based on the energy storage data to be chained.

[0081] Step 104, based on the obtained transaction ID, obtain the corresponding data from the above blockchain and store it in the second database of the above middleware.

[0082] In the embodiment of the present application, the transaction ID can be queried in the blockchain to obtain the corresponding data. After finding the corresponding data, the corresponding data is unchained, that is, the corresponding data is obtained from the blockchain, and then the corresponding data is stored in the second database of the middleware, so that the user can compare the energy storage data to be chained in the first database with the corresponding data in the second database (the corresponding data is the data corresponding to the energy storage data to be chained obtained from the blockchain based on the transaction ID), and then it can be determined whether there is an error in the energy storage data on the blockchain.

[0083] Optionally, after obtaining the corresponding data from the above blockchain based on the obtained transaction ID and storing it in the second database of the above middleware, the above energy storage data management method further includes:

[0084] Determine whether the energy storage data to be chained in the first database is consistent with the obtained corresponding data;

[0085] If the energy storage data to be chained in the first database is inconsistent with the obtained corresponding data, an exception prompt message is output.

[0086] Specifically, the transaction ID can be first queried on the blockchain to determine whether the data corresponding to the transaction ID has been stored in the blockchain;

[0087] If the data corresponding to the transaction ID has not been stored in the blockchain, this step ends;

[0088] If the data corresponding to the transaction ID has been stored in the blockchain, determine whether the type of the data corresponding to the transaction ID is one of the preset specified types. If not, end this step. If so, parse the data corresponding to the transaction ID, and then extract the data corresponding to the above-mentioned energy storage data to be uploaded to the blockchain from the parsed data corresponding to the transaction ID, and store the data corresponding to the above-mentioned energy storage data to be uploaded to the blockchain in the second database of the middleware. It should be noted that the data obtained after parsing the data corresponding to the transaction ID not only includes the data corresponding to the above-mentioned energy storage data to be uploaded to the blockchain, but also includes some information automatically added by the blockchain to this information (such as various tags for easy management, or associated smart contract information). Therefore, it is necessary to extract the data corresponding to the transaction ID after parsing to obtain the data corresponding to the above-mentioned energy storage data to be uploaded to the blockchain.

[0089] Among them, the above-mentioned querying on the blockchain based on the transaction ID to determine whether the data corresponding to the transaction ID has been stored in the blockchain may include:

[0090] Determine the specified block height based on the transaction ID, and then determine the target block based on the hash value included in the block with the above-mentioned specified block height;

[0091] Detect whether the transaction ID list of the above-mentioned target block contains the above-mentioned transaction ID. If it contains, it is determined that the data corresponding to the transaction ID has been stored in the blockchain. If it does not contain, it is determined that the data corresponding to the transaction ID has not been stored in the blockchain.

[0092] Specifically, after obtaining the corresponding data from the above-mentioned blockchain based on the obtained transaction ID and storing the transaction ID and the above-mentioned corresponding data in the second database of the above-mentioned middleware, output a corresponding prompt to inform the user that the energy storage data to be uploaded to the blockchain and the corresponding data of the transaction ID obtained after storing the energy storage data to be uploaded to the blockchain have been respectively stored in the first database and the second database.

[0093] Optionally, the above-mentioned energy storage data management method further includes:

[0094] When receiving a blockchain energy storage data request instruction, determine whether the user who sent the above-mentioned blockchain energy storage data request instruction has the corresponding permission;

[0095] If the above-mentioned user has the corresponding permission, output the decrypted corresponding energy storage data to the above-mentioned user based on the energy storage data requested by the above-mentioned blockchain energy storage data request instruction;

[0096] If the above-mentioned user does not have the corresponding permission, prompt the above-mentioned user that they do not have the corresponding permission.

[0097] Specifically, the user who stores the energy storage data to be chained has the highest level of the above corresponding permissions. The user with the highest level of the above corresponding permissions can fully authorize, partially authorize, or revoke permissions for any other user at will. Fully authorizing a user means granting the user the corresponding permissions to obtain all the data of the above corresponding data. Partially authorizing a user means granting the user the corresponding permissions to obtain some of the data of the above corresponding data. Revoking permissions from a user means taking back the corresponding permissions granted to the user. For example, if an energy storage center uploads an energy storage data to be chained to the blockchain, the energy storage center can perform the above full authorization, partial authorization, or revocation of permissions on nodes or users such as the trading center, the finance department, and the marketing department. Among them, full authorization can be directly sending the above transaction ID to the corresponding user, so that the user who obtains the transaction ID can obtain the corresponding data from the blockchain.

[0098] Specifically, for the energy storage data requested based on the above blockchain energy storage data request instruction, outputting the decrypted corresponding energy storage data to the above user specifically is as follows:

[0099] Query and obtain the corresponding blockchain energy storage data from the blockchain based on the above blockchain energy storage data request instruction, decrypt the above blockchain energy storage data, and then output the decrypted above blockchain energy storage data to the above user.

[0100] As can be seen from the above, the technical solution of the present application obtains the energy storage data to be chained; stores the energy storage data to be chained in the first database of the middleware; performs a chaining operation on the energy storage data to be chained to store the energy storage data to be chained in the blockchain and obtain the corresponding transaction ID; based on the obtained transaction ID, obtains the corresponding data from the blockchain and stores it in the second database of the middleware, so that the user can compare the energy storage data to be chained with the obtained corresponding data to determine whether the obtained corresponding data has changed compared with the energy storage data to be chained, and further determine whether there is an error in the energy storage data on the blockchain, which can effectively improve the reliability of energy storage data management based on the blockchain.
