Detailed Description
The present application will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present application more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.
At present, along with the rapid development of a smart power grid, an intelligent power distribution room is used as one of the most important links for building the smart power grid, and can play roles of improving the reliability of power transmission, improving the power quality and the like. However, with the increasing number of external terminals such as monitoring devices and sensors accessed in an intelligent power distribution room, potential safety hazards are generated by data interaction between power devices and external terminals, so that a new method is needed to ensure the safety of data transmission between the power devices.
As shown in fig. 1, the system for transmitting power data provided by the application comprises a data source device, a network and a data access device, wherein the data source device is communicated with the data access device through the network, the data source device can transmit corresponding power data to the data access device according to an operation instruction sent by the data access device, and the data access device monitors the operation condition of the power device according to the power data sent by the data source device. The data source device may be, for example: the transformer, a sensor for collecting data of the power equipment, a switch cabinet and other equipment; the data access device may be, for example, a server, a terminal device, a portable computer, a desktop computer, or the like when the data access device is a terminal device, and may be of various types such as, but not limited to, a node device of a content distribution network, a storage server of a distributed storage system, a cloud database server, a cloud computing server, a cloud management server, an interaction server, a storage server, a database server, or a proxy server, or the like when the data access device is a server. In some embodiments, each server may include hardware, software, or embedded logic components or a combination of two or more such components for performing the appropriate functions supported by or implemented by the server. For example, a server, such as a blade server, cloud server, etc., or may be a server group consisting of multiple servers, may include one or more of the types of servers described above, etc.
Referring to fig. 2, which is a flowchart illustrating steps of a method for transmitting power data, the method is applied to the data source device in fig. 1, and the method includes the following steps:
step S202, a data access request sent by a data access device is received, wherein the data access request carries a random sequence, and the random sequence is an encryption sequence of target power data.
The data access request may be data of electricity consumption of a cell a for one month, data of abnormal conditions of a transformer on a line B from 1 st month 2021 nd month 6 nd month 30 nd month, data of times of closing operation of a knife gate on a line C from 1 st month 2020 to 12 nd month 31 nd year, etc., which are sent by the data access device, where the data access request may be in a form of encrypted ciphertext, and the data source device may obtain specific content in the data access request after decryption. The power data can be obtained directly from the power equipment, the peripheral equipment for monitoring the power equipment, the peripheral equipment for controlling and operating the power equipment, and the like. The random sequence may be generated by a random sequence generator in a device storing power data, different power devices may store different power data, or different power devices may store the same data, which may be all power data generated by all power devices. The random sequence is used for encrypting the target power data, and the encryption method can be to encrypt and calculate the random sequence and the target power data by using a modulo-2 addition algorithm, an AES encryption algorithm, an IDEA encryption algorithm, a PBE algorithm and the like so that the power data becomes encrypted data.
Illustratively, the temperature sensor receives a data access request sent by the server, and after decrypting the data access request using the public key, the temperature sensor obtains a series of random sequences, such as 01101011. Each random sequence corresponds to one, a group or a class of power data, so that unique power data can be determined according to the random sequence, and the temperature sensor can conveniently search the temperature data from a local memory or a cloud memory.
Step S204, determining the identification of the target power data according to the random sequence, determining the target block corresponding to the target power data according to the identification of the target power data, wherein the target block is used for storing the encrypted data corresponding to the target power data, and the encrypted data is the target power data encrypted by the random sequence.
The identification of the target power data is used for marking the power data and distinguishing the power data from other power data. The target block is a storage space on a preset block chain on the power equipment with the energy storage capability, each block stores corresponding power data, the power data is encrypted by a random sequence, and the identification of the power data corresponds to the block one by one.
Illustratively, after the temperature sensor decrypts the data access request sent by the server according to the above description, a random sequence of the target power data is obtained, then the identifier of the target power data may be found according to the mapping relationship between the random sequence and the power data, and then the corresponding target block is found from the blockchain in the memory address of the temperature sensor according to the identifier of the target power data, for example, the third block may be stored in the third block, where the temperature data encrypted by the 01101011 sequence is stored. The power data is stored on the block chain of the memory address of the power equipment, and the power data stored by the block chain has non-tamper property, so that the situation that the original power data is randomly changed when the data access equipment makes a data request can be avoided, and the safety of the power data is ensured.
Step S206, obtaining the encrypted data from the target block and sending the encrypted data to the data access device.
Illustratively, according to the above operation, after the temperature sensor finds the target block (third block) from the blockchain, the temperature sensor obtains the temperature data required by the server from the third block, where the temperature data is the temperature data encrypted by the 01101011 sequence. Because the temperature sensor transmits the encrypted temperature data to the server, the safety of the temperature data transmission can be ensured, and the safety of the power data transmission is improved.
The application provides a transmission method of power data, which comprises the following steps: the data source equipment receives a data access request sent by the data access equipment, the data access request carries a random sequence, the random sequence is an encryption sequence of target power data, the data source equipment searches the identification of the target power data corresponding to the random sequence from pre-stored sequence mapping information according to the random sequence, and because the target power data is stored in a block chain of the data source equipment, a target block for storing the target power data can be determined from the block chain according to the identification of the target power data, and then the encryption data in the target block is transmitted to the data access equipment. Because the power data acquired by the data access device is stored on the blockchain, the data on the blockchain is tamper-proof, the power data stored on the data source device can be prevented from being tampered maliciously when the data access device accesses the data source device, and the power data is transmitted after being encrypted when the data source device transmits the power data to the data access device, so that the safety of power data transmission is further ensured.
In one embodiment, as shown in fig. 3, which is an optional method step of how the power device stores the generated power data, the method includes:
Step 302, generating a random sequence, and performing exclusive-or processing on the target power data according to the random sequence to obtain encrypted data.
When the power device needs to store the power data, a random sequence is generated for the power data to be stored by a device, such as a random sequence generator, and then the random sequence and the power data to be stored are subjected to exclusive-or processing, that is, decimal is converted into binary, the binary is equal to 0, and the binary is different from 1. After the exclusive OR calculation is carried out on the random sequence and the power data to be stored, the encryption is carried out on the power data, and the safety of the power data storage is guaranteed.
For example, if the power data to be stored is 11000011, the result of the xor operation between 01101011 and 11000011 is 10101000, that is, the data transmitted from the temperature sensor to the server is 10101000, and the server performs the xor operation with the encrypted data by using the random sequence, so that the required power data can be obtained. The encryption processing is carried out on the electric power data, so that the storage safety of the electric power data is improved, and the transmission safety of the electric power data is also improved.
Step 304, a target block is generated according to the encrypted data.
The encrypted data is obtained by performing exclusive-or operation on the generated random sequence and the power data, so that in order to facilitate subsequent searching of the power data, one encrypted data is divided into one block, and each time the power equipment generates one power data, the power data is encrypted first, then divided into blocks and stored in a block chain of the power equipment. The encrypted data is divided into the blocks, so that the encrypted data is conveniently stored in the blockchain, and the power data is stored in the form of the blockchain, and the storage of the blockchain is non-tamper-proof, so that the safety of the power data is ensured, and the condition that illegal users invade and destroy the power data in the power equipment is avoided.
Step 306, checking the target block according to a preset first verification protocol, if the target block passes the check, adding the target block into a block chain of the data source device, wherein the preset first verification protocol is used for checking whether the data format of the encrypted data meets the set data format requirement.
The verification protocol is used for verifying the data format of the encrypted data, and the encrypted data can be added into the blockchain only after the verification is passed. The verification may be that the power device presets a storage rule of the blockchain, where the storage rule is, for example, what format the data should be stored in, what the input and output of the data are, what the structure of the data is, whether the carried digital signature is a digital signature that can be decrypted by the blockchain, and when the encrypted data to be stored is received, the encrypted data is verified according to the preset storage rule, or when the encrypted data meets at least one rule, the encrypted data is uplink, and the power data is stored in the blockchain.
The application provides a transmission method of power data, which is characterized in that before target power data is transmitted, all power data generated by power equipment are stored on a block chain based on a block chain technology, and the power data are stored strictly according to the storage step of the block chain, so that the accuracy of storing the power data is ensured.
In one embodiment, the embodiment is an alternative method embodiment of the power device after generating a corresponding random sequence for the generated plurality of power data, the method comprising:
generating sequence mapping information according to the corresponding relation between the plurality of random sequences and the plurality of power data; the sequence mapping information includes a correspondence of the random sequence and the power data identification.
Optionally, the present embodiment is an identification for determining power data corresponding to a random sequence, including:
and determining the identification of the power data corresponding to the random sequence according to the sequence mapping information and the random sequence.
Illustratively, the sequence mapping information includes random sequences generated by a plurality of data source devices and power data identifiers corresponding to each of the random sequences. After the data source device receives the data access request carrying the random sequence 01101011, the data source device searches the random sequence from the pre-stored sequence mapping information, and then finds the identifier 7 of the target power data corresponding to the 01101011 sequence.
The application provides a transmission method of electric power data, which comprises the steps of generating a corresponding random sequence for the electric power data when the electric power equipment stores the electric power data, and then establishing sequence mapping information of the random sequence and an electric power data identifier, wherein the data source equipment can quickly find the identifier of the target electric power data from the sequence mapping information according to the random sequence after sending a data access request carrying the random sequence to the data source equipment by the data source equipment through the sequence mapping information, thereby being convenient for quickly acquiring the electric power data from a block chain and improving the efficiency of data transmission.
In one embodiment, as shown in FIG. 4, this figure is an optional method step that occurs during the storage of power data by a power device, the method comprising:
in step 402, the correspondence between the plurality of power data and the plurality of blocks is recorded.
Step 404, generating block mapping information according to the correspondence between the identification of the power data and the serial number of the block; the block mapping relationship includes a correspondence relationship between an identification of the power data and a number of the block.
Optionally, determining a target block corresponding to the power data according to the identification of the power data and the block mapping information.
For example, after generating the power data, the power device needs to store the power data in the blockchain, and since the data on the blockchain is stored in blocks, in order to facilitate the subsequent fast acquisition of the target power data from the blockchain, the power device performs the above encryption processing on the plurality of power data, and then performs the block division processing on the plurality of encrypted data, so that each block stores different power data. After the blocks are divided, a one-to-one correspondence of the random sequence, the power data and the blocks is generated, and according to the description, the power equipment encrypts the power data by using the generated random sequence and then generates correspondence information of the random sequence and the power data identifier according to the relationship of the random sequence and the power data. The power equipment generates block mapping information of the power data identification and the block number according to the corresponding relation between the power data and the block, so that the power equipment can quickly find the corresponding block number from the block chain according to the identification of the target power data determined by the random sequence, and then take out the required data from the target block.
According to the power data transmission method provided by the embodiment of the application, the power equipment builds the corresponding relation between the power data identification and the block number, so that the power equipment can quickly find the target block from the block mapping information of the power data and the block according to the power data identification determined by the random sequence, and the data transmission efficiency is improved.
Referring to fig. 5, which is a flowchart illustrating steps of a method for transmitting power data, the method is applied to the data access device in fig. 1, and the method includes the following steps:
step S502, receiving triggering operation of a user; the triggering operation carries the user identification and the identification of the target power data.
The data access device is, for example, a computer device, and then a user can trigger an operation on the power data through a keyboard (input device) on the computer, so that the computer device performs data interaction with the power device, and the user obtains the required power data and operates the obtained power data. In order for the computer device to recognize the user's intent, the triggering operation carries an identification of the user and an identification of the power data requested by the user. The user identifier may be, for example, a login password set by the user, fingerprint information of the user, voice information of the user, or some identifier capable of distinguishing the user, which is not limited in the present application.
Step S504, checking the user according to the user identification.
In order to ensure the safety of access, the data access equipment prohibits an illegal user from logging in the system, and the verification mode can be that the user identification of a legal user is stored in the data access equipment, the user identification is compared with the stored legal user identification, and if the comparison is consistent, the verification is successful; or, calculating the user identifier, comparing the obtained value with a pre-stored value, if the comparison is consistent, checking successfully and the like; there are other ways to verify the user identity, which the present application is not limited to.
Step S506, when the verification passes, determining a random sequence of the target power data according to the identification of the power data.
