Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1, a schematic diagram of steps of a method for securely storing electric energy data according to an embodiment of the present invention is shown.
It should be noted that, the method for safely storing electric energy data provided by the embodiment of the invention can be executed by the system for safely storing electric energy data, and the embodiment uses each component module in the system for safely storing electric energy data as an execution main body. The safe storage system of the electric energy data comprises a terminal server, a base station acquisition server and a plurality of electric energy meter devices.
In the embodiment of the present invention, the method for safely storing the electrical energy data is performed by steps S1 to S3:
s1, each electric energy meter device stores own electric energy data in real time, and the Mesh network group is adopted to send the own stored electric energy data to other electric energy meter devices; and randomly receiving and storing the electric energy data sent by other electric energy meter devices.
S2, the acquisition base station server acquires the electric energy data stored by each electric energy meter device in real time, and generates a blockchain for storing information summaries according to the acquired electric energy data and the acquisition time sequence; and periodically transmits a data uploading request to the terminal server.
And S3, the terminal server invokes the blockchain uploaded by the acquisition base station server according to the data uploading request of the acquisition base station server.
In the embodiment of the present invention, referring to fig. 2, a schematic structural diagram of a real-time data acquisition system in the embodiment of the present invention is shown. Each electric energy meter device comprises a client or a memory, and the client or the memory is used for storing electric energy data generated by the data node and storing electric energy data sent by other electric energy meter devices. The appointed number of electric energy meter devices are associated in a Mesh network group mode to form a real-time data accounting system. In the real-time data accounting system, each electric energy meter device generates and stores electric energy data, and sends the electric energy data of the electric energy meter device to other electric energy meter devices in a broadcasting mode in a network communication mode, and meanwhile, the electric energy data of the other electric energy meter devices are received, so that the mutual storage of the electric energy data among data nodes is realized, and the possibility that the electric energy data of the electric energy meter devices are tampered is reduced.
Preferably, in step S1, the electric energy meter device randomly receives and stores electric energy data sent by other electric energy meter devices, and specifically includes:
s11, each electric energy meter device verifies the identity of the electric energy meter device which sends electric energy data;
and S12, after the identity verification of the electric energy meter device transmitting the electric energy data is passed, randomly receiving and storing part or all of the electric energy data transmitted by the electric energy meter device transmitting the electric energy data.
Specifically, each meter device has a fixed ID, and the meter device needs to verify the authenticity of its ID before receiving the power data sent by other meter devices. And after the identity verification is passed, randomly receiving the electric energy data sent by other electric energy meter equipment, and recording the received data on the respective account book to form a data block.
By adopting the embodiment of the invention, the identity of other electric energy meter equipment is verified, so that the possibility that a hacker invades a system to impersonate and send false data can be effectively reduced; the electric energy meter device only receives part or all of electric energy data sent by other electric energy meters, so that the randomness of electric energy data storage is increased on the basis of guaranteeing the integrity of electric energy data storage, and compared with the independent data storage of each electric energy meter device in the prior art, the situation that the electric power theft is caused by malicious tampering of the data of one electric energy meter device can be more effectively prevented.
Further, the acquisition base station server manages each electric energy meter device to form the real-time data acquisition system, so that the distributed storage of the real-time electric energy data is realized.
Preferably, in step S2, the collecting base station server collects the electric energy data stored in each electric energy meter device in real time, and generates a blockchain storing the information abstract from the collected electric energy data according to the collection time sequence, which specifically includes steps S21 to S23:
s21, the acquisition base station server acquires the electric energy data stored by each electric energy meter device in real time.
S22, the acquisition base station server detects the consistency of the electric energy data acquired by the acquisition base station server and the electric energy data stored by the electric energy meter equipment; detecting the availability of the electric energy data acquired by the self; detecting partition tolerance of the electric energy data acquired by the self;
s23, when the collected electric energy data meet preset consistency, availability and partition tolerance conditions, the collection base station server generates a blockchain for storing information summaries according to the collection time sequence from the collected electric energy data.
In the embodiment of the invention, the consistency means that the electric energy data transmitted between the base station server and each electric energy meter device are collected at the same time. Because the acquisition base station is connected with each electric energy meter through network communication, the network communication is not necessarily reliable, and when the network is abnormal, the inconsistency of electric energy data between the acquisition base station and each electric energy meter is easily caused. And the method for acquiring the Kendall W coordination coefficient of the base station server performs query and check on the consistency of the data. Whether the inconsistency occurs is judged by querying the state of the operation or querying the difference of the data or the message.
Specifically, the acquisition base station server detects the network connection state of the acquisition base station server and each electric energy meter device. When the network connection state with the electric energy meter equipment is abnormal, the electric energy data acquired by the electric energy meter equipment at the current moment is not consistent with the electric energy data of the electric energy meter equipment, namely the electric energy data acquired by the electric energy meter equipment is considered to meet the consistency condition; when the network connection state with the electric energy meter equipment is normal, the electric energy data acquired by the electric energy meter equipment at the current moment is considered to be consistent with the electric energy data of the electric energy meter equipment, namely the electric energy data acquired by the electric energy meter equipment is considered to not meet the consistency condition.
Preferably, when the collecting base station server detects that the power data does not meet the consistency condition, a compensation action needs to be performed. When the data of each electric energy meter is uploaded to the acquisition base station server in each operation, flash memory backup is firstly carried out locally, and when the acquisition base station server detects that the electric energy data are inconsistent, namely the data are transmitted and uploaded in a failed mode, the electric energy meter equipment is controlled to roll back to the transmitting operation to upload the data again.
Further, "availability" means that after the acquisition base station server sends an acquisition request to the electric energy meter device, the electric energy meter needs to process the request and respond in a limited time. When a problem occurs in read-write operation of more than a certain number of electric energy meter devices in the system, and a result cannot be returned in a preset time, the electric energy data currently collected by the collection base station server is considered to be unavailable.
Specifically, the collecting base station server detects whether the electric energy data collected by the collecting base station server is returned by electric energy meter devices exceeding a first preset number within a preset time threshold after the collecting base station server sends a collecting request. If yes, the electric energy data acquired by the self is considered to meet the availability condition; if not, the electric energy data acquired by the self-service device is considered to not meet the availability condition.
The preset time threshold and the first preset number may be set according to actual operation conditions, for example, the response result of the electric energy meter device that receives more than 80% of the total number within 5 minutes after the acquisition base station server sends the acquisition request is set, and the acquired electric energy data can be considered to satisfy the availability condition.
Further, "partition tolerance" means that the system can continue to operate when a network partition occurs, such as when the network breaks, programs bug, crashes, etc. After the problem of one or more electric energy meters, the normally-running clothes collecting base station server and other electric energy meters can still normally provide service, and the designed consistency and usability are met. The method for improving the partition tolerance is that the electric energy data of one electric energy meter device is sent and stored to a plurality of electric energy meter nodes, so that after the partition occurs, the data item can be distributed into each area, and the tolerance is improved. In general, the more nodes the power data is present, the higher the partition tolerance.
Specifically, the collecting base station server detects whether the electric energy data sent by each electric energy meter device receive the receiving replies of the electric energy meters exceeding the second preset quantity. If yes, the electric energy data acquired by the self is considered to meet the partition tolerance condition; if not, the electric energy data acquired by the self-service device is considered to not meet the partition tolerance condition.
The second preset number may be set according to actual operation conditions, for example, the second preset number is set to 50% of the total number of electric energy meter devices.
Further, when the acquisition base station server detects that the acquired electric energy data meets preset conditions of consistency, availability and partition tolerance, the acquisition base station server generates a blockchain for storing the information abstract according to the acquisition time sequence.
The blockchain is a chained database which is formed by combining data blocks in a sequential connection mode according to a time sequence, and is a distributed account book which is guaranteed in a cryptographic mode and cannot be tampered and counterfeited. In the embodiment of the invention, the collecting base station server performs summarization processing on the collected electric energy data of each electric energy meter device to generate an electric energy data abstract, generates a block chain according to the collecting time sequence, and sends a data uploading request to the terminal server at regular time.
Further, in step S3, the terminal server invokes the blockchain uploaded by the acquisition base station server according to the data upload request of the acquisition base station server, and specifically includes:
s31, the terminal server performs identity authentication on the acquisition base station server according to the data uploading request of the acquisition base station server.
S32, when the identity authentication of the acquisition base station server is passed, the blockchain uploaded by the acquisition base station server is called.
Specifically, the acquisition base station server sends an uploading request to the blockchain network, and parameters such as hash values, information types and the like are transmitted into the blockchain network; the block chain link point receives the request, firstly verifies the user identity, binds the hash value, the client ID, the data acquisition node ID, the query data type and the data acquisition time through the post-execution intelligent contract, and broadcasts the request to other nodes to execute the same operation; and then writing the execution result into the blockchain ledger after consensus among the nodes is achieved.
In the embodiment of the invention, the identity authentication between the acquisition base station server and the terminal server is based on a digital signature algorithm, and a public key encryption technology is adopted to generate a digital certificate for each data abstract so as to identify the identity of the user. The sender of the data digest generates a hash value from the text of the data digest, and the sender encrypts the hash value with its own private key to form the sender's digital signature. This digital signature is then sent to the recipient as an attachment to the message along with the data summary message. The receiving side of the message first calculates a hash value from the received original message, and then decrypts the digital signature attached to the message with the public key of the sending side. If the two hash values are identical, the recipient confirms the sender identity of the digital signature. The identity authentication of the original data abstract can be realized through digital signature.
By adopting the technical means of the embodiment of the invention, the terminal server receives the blockchain from each real-time data acquisition system and changes the original situation of facing a large number of electric energy meter devices into the situation of facing a plurality of real-time data acquisition systems. Because the terminal server accesses each real-time system in a time-sharing way, the problems of huge storage consumption and waste of a large amount of resources caused by independent uploading of data by the electric energy meter equipment in the prior art are solved, the terminal server can be better enabled to effectively schedule transportation resources to analyze corresponding data, and the defects of data blocking, multiple iterative data times and slow updating are effectively overcome. In addition, identity authentication is carried out in the data transmission process of the terminal server and the acquisition base station server, so that malicious tampering in the data uploading process is effectively avoided, and the safety of electric energy data is further provided.
In the embodiment of the invention, based on the characteristic of 'distributed' of the blockchain, the data barriers among departments can be opened, and information and data sharing can be realized. Different from the centralized data storage, the information on the blockchain is distributed to each node in a point-to-point broadcast mode, and the real recording of all the information is realized through the whole network witness, so that a common-knowledge mechanism is formed, and the purpose of secure storage which cannot be tampered is achieved.
The embodiment of the invention provides a safe storage method of electric energy data, each electric energy meter device stores the electric energy data of the electric energy meter device in real time, and a Mesh network group is adopted to send the electric energy data stored by the electric energy meter device to other electric energy meter devices; and randomly receiving and storing the electric energy data sent by other electric energy meter devices; the acquisition base station server acquires the electric energy data stored by each electric energy meter device in real time, and generates a blockchain for storing the information abstract according to the acquired electric energy data and the acquisition time sequence; and sending a data uploading request to a terminal server at regular time; and the terminal server invokes the blockchain uploaded by the acquisition base station server according to the data uploading request of the acquisition base station server. According to the embodiment of the invention, the random scattered storage of the electric energy data is realized by associating the electric energy meter devices, the possibility that the electric energy data is tampered in the storage and transmission processes is effectively avoided, the reliability, availability and access efficiency of the electric energy data storage and transmission are improved, and the electric energy meter device is easy to expand.
