This kind of electricity meter can provide strong support for power management and energy conservation, and gradually become an important part of the construction of smart grids. Therefore, there is an urgent need for an electricity meter based on real-time data dual-mode communication. Summary of the Invention

[0004] The present invention proposes an electricity meter based on real-time data dual-mode communication, which solves the problems in the prior art of achieving flexible switching between wired communication and wireless communication, ensuring stable data transmission and the realization of remote monitoring, and at the same time ensuring data security.

[0005] The technical solution of the present invention is realized as follows: An electric energy meter based on real-time data dual-mode communication. A communication module is arranged in the inner cavity of the electric energy meter body. The communication module includes data interaction among a dual-mode transmission communication unit, a data fusion unit, an autonomous network unit, and a security encryption unit; the dual-mode transmission communication unit is internally provided with a wired communication unit and a wireless communication unit. When the wired communication unit and the wireless communication unit send data, the data is encrypted by the security encryption unit and then sent to the background server and the data acquisition device; the data fusion unit checks, de-duplicates, sorts the data received by the wired communication unit and the wireless communication unit, then compresses and converts the format of the received data. After unifying the data format, the data is sent to the security encryption unit for decryption operation; the autonomous network unit establishes an ad-hoc network within a set range through a protocol.

The data is encrypted by a symmetric encryption or an asymmetric encryption algorithm, and the encrypted data is written into the blockchain node. When the dual-mode transmission communication unit, the data fusion unit, and the autonomous network unit send data, the data is sent through the blockchain node.

[0006] Compared with traditional electric energy meters, the electric energy meter in this application document usually only has a wired communication module, while this electric energy meter integrates a dual-mode transmission communication unit, a data fusion unit, an autonomous network unit, and a security encryption unit, enabling the electric energy meter to have more flexible and diverse communication methods, and can realize the switching and fusion of wired and wireless communications. By setting a security encryption unit in the communication module, the electric energy meter can perform encryption processing during data transmission, thus better ensuring the security of data and preventing data leakage and tampering. The practice of writing data into the blockchain node provides higher security and immutability for data storage, which is not available in traditional electric energy meters.

[0007] An ad-hoc network is established through the autonomous network unit to realize data interaction between adjacent electric energy meters. This function helps to improve the efficiency and stability of data transmission, and at the same time reduces the construction and maintenance costs of the system.

[0010] As a preferred embodiment, the data fusion unit sorts out the data collected by the wired communication unit and the wireless communication unit, and then performs cleaning and preprocessing. After removing duplicate data, processing missing values, and correcting incorrect data, the data from different data sources is integrated, data format conversion, unit unification, and time alignment are performed, and then the fused data is sent to the security encryption unit.

[0011] As a preferred embodiment, the autonomous network unit sends a detection signal to search for surrounding devices. After discovering the surrounding devices, a communication connection is established between adjacent nodes, and the decoded data is received through the data encryption unit and the wireless communication unit for signal exchange and confirmation.

[0017] Example:

[0018] like Figure 1 As shown, an electric energy meter based on real-time data dual-mode communication, a communication module is arranged in the inner cavity of the electric energy meter body, and the communication module includes a dual-mode transmission communication unit, a data fusion unit, an autonomous network unit and a security encryption unit for data exchange; the dual-mode transmission communication unit has a wired communication unit and a wireless communication unit built in, and when the wired communication unit and the wireless communication unit send data, they encrypt the data through the security encryption unit and then send the data to the background server and the data acquisition device; the data fusion unit verifies, removes duplications, and sorts the data received by the wired communication unit and the wireless communication unit, and then compresses and converts the received data to unify the data format After that, the data is sent to the security encryption unit for decryption; the autonomous network unit establishes an ad hoc network within a set range through a protocol, and adjacent electric energy meters exchange data through the ad hoc network unit, and during the interaction, the data is encrypted and decrypted through the security encryption unit; the security encryption unit receives data from the dual-mode transmission communication unit, the data fusion unit and the autonomous network unit, and encrypts the data to be encrypted, encrypts the data through a symmetric encryption or an asymmetric encryption algorithm, and the encrypted data will be written into the blockchain node. When the dual-mode transmission communication unit, the data fusion unit and the autonomous network unit send data, the data is sent through the blockchain node.

[0019] The electric energy meter realizes data collection, encryption, transmission and storage through the built-in communication module. The following is a detailed description of the working principle and process of the electric energy meter:

[0020] Dual-mode transmission communication unit: The electric energy meter is equipped with a built-in dual-mode transmission communication unit, including a wired communication unit and a wireless communication unit. These two units can send and receive data at the same time, which improves the reliability and flexibility of communication. When sending data, the dual-mode transmission communication unit will first encrypt the data through the security encryption unit.

[0021] Data Fusion Unit: The data fusion unit is responsible for processing the data received by the dual-mode transmission communication unit. It performs data verification, deduplication, and sorting operations to ensure the accuracy and consistency of the data. The data fusion unit also compresses and converts the format of the received data to unify the data format. The fused data is sent to the security encryption unit for decryption operations.

[0022] Autonomous Network Unit: The autonomous network unit enables the electricity meter to establish an ad-hoc network within a set range through a protocol. Adjacent electricity meters can interact with each other through the autonomous network unit. During the data interaction process, the security encryption unit is responsible for encrypting and decrypting the data.

[0023] Security Encryption Unit: The security encryption unit receives data from the dual-mode transmission communication unit, the data fusion unit, and the autonomous network unit. It is responsible for encrypting the data that needs to be encrypted, using symmetric encryption or asymmetric encryption algorithms. The encrypted data will be written into the blockchain node, enhancing the security and immutability of the data. When the dual-mode transmission communication unit, the data fusion unit, and the autonomous network unit send data, the data is sent through the blockchain node. This ensures the security and traceability of data transmission.

[0024] When the security encryption unit writes the encrypted data into the blockchain node, it performs a hash processing on the encrypted data, converting the data into a hash value of a fixed length. This is used to quickly verify the integrity of the data during data transmission decryption, and after uploading the data to the blockchain node, the data is verified and stored in multiple nodes in the distributed network. Before writing the encrypted data into the blockchain, the security encryption unit performs a hash processing on the encrypted data. Hash processing is a process of converting input data of any length into an output of a fixed length (hash value). If the hash function is well-designed, even a tiny change in the input data will result in a huge change in the hash value, which is called the avalanche effect. Hash values are usually used to quickly verify the integrity of data because any change in the original data will cause a change in the hash value. During data transmission decryption, the integrity of the data can be quickly verified by performing a hash processing on the received data again and comparing it with the original hash value. If the calculated hash value matches the original hash value, it can be confirmed that the data has not been tampered with during transmission, ensuring the integrity of the data. The data after hash processing (including the hash value of the original data) will be uploaded to the blockchain node. In the blockchain, each data block usually contains a series of transaction data and the hash value of the previous block, and this chain structure ensures the immutability of the data.

[0025] A blockchain is a decentralized distributed ledger where data is not stored on a single node but replicated and stored on multiple nodes in the network. When new data (blocks) are added to the blockchain, nodes in the network execute a series of algorithms to verify the validity of the new data. Once the data is verified as valid, it is added to the blockchain and synchronized among all nodes, ensuring that each node has a complete and consistent copy of the data.

[0026] In this way, the security encryption unit combines hash processing and blockchain technology, not only protecting the security and integrity of data during transmission, but also enhancing the data security and transparency of the entire system by leveraging the decentralized and immutable nature of the blockchain. This mechanism is very important for applications such as electricity meters that require ensuring data accuracy and security, as the data of electricity meters is directly related to key operations such as billing and energy management.

[0027] The data fusion unit sorts out the data collected by the wired communication unit and the wireless communication unit, and then performs cleaning and preprocessing. After removing duplicate data, handling missing values, and correcting incorrect data, it integrates the data from different data sources, performs data format conversion, unifies units, and aligns time. Subsequently, the fused data is sent to the security encryption unit. The data fusion unit first sorts out the data collected by the wired communication unit and the wireless communication unit. This includes classifying, sorting, or organizing the data to facilitate subsequent cleaning and preprocessing steps. Data cleaning is the process of removing inaccurate, incomplete, or irrelevant parts from the collected data. This step may include removing duplicate data to ensure that the same data is not calculated or analyzed multiple times. Handling missing values is done by filling in the missing data or deleting records containing missing values. Correcting incorrect data involves identifying and correcting errors generated during data collection or transmission. The data fusion unit integrates the data from different data sources. This step ensures that even if the data comes from different communication methods (wired or wireless), it can be uniformly processed and analyzed. The data fusion unit plays a crucial role in the electricity meter. It ensures the accuracy and availability of data through cleaning and preprocessing, and prepares high-quality data for subsequent encryption and transmission. Such a processing flow is very important for ensuring the integrity and consistency of electricity meter data, especially in application scenarios that require accurate billing and efficient energy management.

[0028] The autonomous network unit sends out detection signals to search for surrounding devices. After discovering the surrounding devices, it establishes communication connections between neighboring nodes, and receives and decodes data through the data encryption unit and the wireless communication unit for signal exchange and confirmation. The autonomous network unit first sends out detection signals, which are used to search for and discover surrounding devices. The detection signals are usually radio signals used to identify other devices with communication capabilities in the surrounding area. The autonomous network unit determines which surrounding devices can be used to establish communication by sending out detection signals. This process may involve listening for response signals or scanning at a predetermined frequency to discover other devices. Once surrounding devices are discovered, the autonomous network unit attempts to establish communication connections with these devices. These connections are usually wireless and support two-way data transmission. The communication connections between neighboring nodes may be based on a certain wireless communication standard or protocol, such as Wi-Fi, Bluetooth, ZigBee, etc.; After establishing communication connections between neighboring nodes, all data transmitted through these connections will pass through the data encryption unit. The data encryption unit encrypts the transmitted data to ensure the security and privacy of the data during wireless transmission. Once the data is decoded, signal exchange is performed between the devices to confirm that the data has been successfully received and understood. This includes sending confirmation messages or performing handshake protocols to ensure the reliability of communication; The autonomous network unit plays a role in establishing and maintaining a communication network between neighboring devices in the electricity meter. By sending out detection signals and establishing communication connections, it allows electricity meters to communicate with each other and exchange data. At the same time, combined with the function of the data encryption unit, it also ensures the secure transmission of data, preventing the data from being intercepted or tampered with during wireless transmission. Such a mechanism is very crucial for establishing a network of electricity meters in the smart grid, which supports the real-time collection and analysis of data, improving the operation efficiency and reliability of the power grid.

[0029] After two devices establish a communication network through the autonomous network unit, the autonomous network unit is a module within the device for automatically forming a communication network. Once the devices establish a communication network through the autonomous network unit, they can communicate with each other without relying on external infrastructure. The security encryption unit sets up dedicated blockchain nodes. The security encryption unit is inside the device and is used for data encryption and decryption. By setting up dedicated blockchain nodes, it means that the device has its own blockchain nodes for storing encryption keys and information related to communication paths. Establishing a communication path in the blockchain node means that the communication path information between devices will be recorded in the blockchain node. The immutability and distributed characteristics of blockchain technology ensure the security and reliability of the communication path information. And after the first encryption and decryption verification, passwordless communication is carried out for the devices that have established the communication path. Passwordless communication for the devices that have established the communication path: During the first communication, the devices will go through the processes of encryption, decryption, and verification. Once the first verification is passed, the communication path between the devices will be confirmed and recorded on the blockchain. After that, these devices can conduct passwordless communication, which means they can directly perform encryption and decryption operations without further verification.

[0030] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
