State Grid Fujian Power Applies for Patent on Blockchain-based Meter Calibration Data Management, Enhancing Data Security and Transparency

Finance.jr.com, October 24, 2024 - According to information from the State Intellectual Property Office, the Marketing Service Center of State Grid Fujian Electric Power Co., Ltd., State Grid Xin Tong Yi Li Technology Co., Ltd., and Fujian Electric Power Service Co., Ltd. have applied for a patent titled "A Method and System for Blockchain-based Meter Calibration Data Management," with publication number CN118796946A and an application date of July 2024.

This patent aims to address the shortcomings of existing meter calibration data management, specifically the inadequate data security and transparency. It proposes a blockchain-based solution. The method and system include the following key steps:

1. Data Acquisition and Preprocessing: Metering devices collect data using multiple sensors, and edge computing devices are used for preprocessing, improving data processing efficiency.

2. Data Compression and Encryption: Data aggregation and compression techniques are employed to reduce data volume, and secure communication protocols are used to encrypt data, ensuring security during data transmission.

3. Cloud Platform Upload: Encrypted data is uploaded to the cloud platform via API interfaces for centralized management.

4. Blockchain Storage: The cloud platform uploads encrypted data to the blockchain network, leveraging blockchain's immutability to ensure data integrity and reliability.

5. Hybrid Consensus Mechanism: A hybrid consensus mechanism is implemented, combining the advantages of different consensus algorithms to enhance the security and efficiency of the blockchain network.

6. Data Query: Users can submit data query requests through visualization units. The cloud platform retrieves relevant metadata from the blockchain and data files from the IPFS distributed storage system, decrypts and processes them before displaying them to users.

The blockchain-based meter calibration data management method and system proposed in this patent effectively ensure secure data storage and transmission by storing data on the blockchain network, enhancing the transparency and credibility of meter calibration data management. The system also leverages edge computing and distributed storage technology to improve data processing efficiency and access speeds.

The application of this patent technology will effectively address data security and transparency issues in meter calibration, providing a more secure and reliable solution for data management in the power industry, and driving the application and development of blockchain technology in the energy sector.
