Background
With the rapid development of smart home and energy management, smart meters are widely used in households and enterprises. However, the existing data acquisition management system for the smart meter has some problems that the transmission speed of the smart meter is very slow due to the limitation of a communication protocol and a transmission mode, and even the situation of data transmission interruption occurs. Because of the lack of unified data exchange standards and interfaces, data interaction and sharing among intelligent electric meters of different manufacturers are difficult to realize, and the overall control of users on data can be affected. Due to limitations of data acquisition algorithms and sensor technology, the data of the intelligent ammeter can be wrong and inaccurate. In addition, the problems of communication delay, data errors, low data accuracy, data leakage, tampering and loss, various and difficult unification of data formats, insufficient system stability and easy malicious attack of the system exist.
Disclosure of Invention
The invention aims to provide a data acquisition management system applied to a smart meter, so as to solve the problems in the background technology.
In order to solve the technical problems, the invention provides the following technical scheme: the data acquisition management system comprises a data acquisition module, a data processing module, a communication module, a storage module, a user interface module and a safety management module; the data acquisition module comprises a data acquisition unit and a data encryption unit; the data processing module comprises a data processing unit and a data query unit; the communication module comprises a data synchronization unit and a data backup unit; the data storage module comprises a storage unit and a data sharing unit; the user interface module comprises a data output unit and a data retrieval and inquiry unit; the safety management module comprises a data maintenance unit and a safety management unit. The data collection module collects data from the data sources using smart contract technology in the blockchain. An intelligent contract is an automated execution code that records data through a consensus mechanism between multiple nodes. By using a hash function for encryption, the hash function takes plaintext data as input, outputs a hash value with a fixed length through processing, can be used as ciphertext for storage and transmission, and has a data verification function so as to ensure the accuracy and the effectiveness of the data. And the interface of the intelligent electric meter is in communication connection with the blockchain service platform and the SQL database, the intelligent electric meter sends an identity authentication request to the blockchain service platform, after authentication, a first public key and a first private key are generated, and the first public key is sent to the blockchain service platform. And the intelligent ammeter encrypts the locally stored electricity data through a first private key and sends the encrypted data to the blockchain service platform. The block chain service platform decrypts the electricity data through the first public key and writes the hash value of the decrypted electricity data into the block chain. The intelligent ammeter sends the electricity consumption data to an SQL database, the SQL database compares the hash value of the received electricity consumption data with the hash value written into the block chain, and whether the data is tampered is determined according to the comparison result. The transaction is initiated by the user and broadcast to all accounting nodes, which record all account book information, verify whether the transaction is correct, and complete accounting. There are three decentralization strategies for blockchains: private chain, federated chain, public chain. A private chain is a blockchain that is commonly owned by a single trusted node, typically controlled by an organization or entity. In private chains, the reliability and security of data is typically guaranteed by a single trusted node, and such blockchains are typically used for business processing and data management within an enterprise. When the data recorded by the accounting node is inconsistent, the trust node is subject to control. The alliance chain is a decentralization system constructed by nodes in an organization, any node in the organization has certain authority and responsibility, and decentralization is realized by voting. The alliance mode is commonly used for mutual cooperation and data sharing among enterprises, so that the reliability and the safety of data can be ensured, and meanwhile, the mutual restriction and supervision in an organization can be realized. The public chain is a fully de-centralized blockchain, and any node can join and leave at any time. When the recorded data of each node are inconsistent, a cryptographic hash function can be used for drawing a lottery, if 43 0 s are in front, the content of the account book is determined by the lottery, and other nodes are consistent with the lottery; if a malicious node is drawn, its ability to modify the data is limited. The public chain has the highest degree of decentralization, the highest degree of freedom and the lowest trust cost. In a blockchain network, when a certain accounting node is inconsistent with data recorded by other accounting nodes, a decentralizing policy flow can be triggered. Detecting data through an intelligent contract, judging whether a central node exists or not, and if the central node exists, taking the data recorded by the central node as the reference; judging whether the main participant is a B-end user or not when the central node does not exist; the B-end user refers to enterprises, governments and banks with a certain scale of institutions and organizations; when the main participant is the B-end user, adopting a alliance chain; the public chain is employed when not the B-terminal user. And the data processing module performs data cleaning and preprocessing on the acquired user data. Screening, classifying, labeling and removing invalid data from the acquired data by utilizing a data analysis technology; and setting access control, remote control and remote alarm functions, generating a power consumption report and an analysis chart according to the requirements of a user, and providing a visual page. And can query data using SQL statements without querying the blockchain itself. Since the SQL database stores validated transaction data, the SQL query statement can be used to quickly retrieve and query data on the blockchain, which can be accomplished by periodically reading the latest data from the blockchain and updating the SQL database. The blockchain network is used as a main database, the SQL database is used as a backup database, and the SQL database stores transaction data in the verified blockchain, so that the SQL query statement can be used for quickly searching and querying the data on the blockchain. And (3) encrypting the user data by a hash function, and writing the hash value into the block chain, wherein different data correspond to different hash values. The hash function has unidirectional irreversibility, so that the data source can not be calculated through the hash value in turn, and the non-tamper property and the security of the data are ensured. And only users with authority can access and process the data, thus avoiding data leakage and improving the use experience of the users. The communication module is responsible for uploading the processed data to the blockchain network and backing up the data. The data storage module adopts a distributed account book mode to store data in a plurality of network nodes so as to solve the problems of user data leakage, loss, tampering and system attack. The user interface module outputs data to the user, so that the user can conveniently and intuitively know the data. User electricity data is stored in the blockchain network, the blockchain network is used as a main database, the SQL database is used as a backup database, and the data stored in the blockchain can be set to be backed up every minute. Blockchains store data in multiple network nodes in a distributed ledger fashion, rather than centrally on a single centralized server. Each node contains a copy of the data, thus enabling each participant to share and access the data. The intelligent contract on the blockchain is an automatic program code, can define and execute rules and conditions of data sharing, and improves the efficiency and reliability of the data sharing. The method can interact with the user, starts from the historical payment record of the user, uses the form of a chart to count the use frequency of the electric quantity of the user, generates a bill, distinguishes the estimated quantity from the actual quantity, and realizes accurate settlement; the user can inquire data, bill and alarm information through WeChat applet, WEB and APP modes, and any user added into the blockchain network can check and verify transaction information, so that the transaction is transparent, safe and reliable. The user with the authority can check the own electricity consumption data at any time. The module can also receive a setting instruction of a user so as to realize personalized customization and management of electricity consumption data by the user, the user can purchase packages according to the actual consumption condition of the user, the part of the packages which are not used can carry out point exchange, and after the points reach a certain quantity, the electric charge can be deducted; and the upper limit early warning of the package can be set, so that the electric quantity is reasonably used. The security management module is responsible for maintaining the security and reliability of the whole system, and adopts a hash encryption technology, a consensus mechanism and an intelligent contract to ensure the security and stability of data; in addition, the module can also detect, monitor and alarm the running condition of the system, and backup the whole network data by using the SQL database to ensure the normal running of the system. The entire blockchain network adopts a consensus mechanism to ensure that participants agree on transactions and promote trust and collaboration among different participants.
Compared with the prior art, the invention has the following beneficial effects:
the traditional centralized system has the problems of single-point failure and unreliability, and the decentralization characteristic of the blockchain technology ensures that the storage and management of transaction records and intelligent contract data are independent of a central mechanism, can be shared and verified in the whole network, ensures that the data are not controlled by any single mechanism or person, and improves the safety and reliability of the system. In the blockchain system, all nodes can check the transaction records of the account book, and each transaction is public, so that the transparency can ensure the fairness and traceability of the transaction, and the possibility of fraudulent behavior and misbehavior is reduced. Since each block of the blockchain system contains the hash value of the previous block, tampering with a block will result in the hash values of all blocks on the blockchain being changed, and thus this non-tampering ensures the security of the transaction. The decentralization, transparency and consensus mechanism of the blockchain technology enable each node to trust each other, and data sharing and interaction are achieved. The blockchain technique is more secure than conventional centralized systems because it is decentralised and non-tamper-resistant.
