A Patent Granted for a Blockchain-Based Secondary Market Metering Device Management Method

On February 12, 2025, the State Intellectual Property Office of China announced the authorization of a patent titled "A Blockchain-Based Secondary Market Metering Device Management Method," jointly applied for by Fujian Wangneng Technology Development Co., Ltd. and State Grid Information and Communication Industry Group Co., Ltd. The patent, with publication number CN119396927A, was filed in October 2024. This achievement marks significant progress in utilizing blockchain technology to improve the efficiency of secondary market metering device management and offers a new direction for technological innovation in the field.

The core of this patent application lies in proposing a novel blockchain-based management method for secondary market metering devices. The technical solution cleverly leverages the decentralized, transparent, and tamper-proof nature of blockchain technology to construct a secure, reliable, and efficient management system. This invention aims to address the issues of information silos, data security, and low efficiency prevalent in traditional secondary market metering device management.

The patent abstract details the specific steps of the method. First, it establishes five key nodes: the manufacturing node, the construction and maintenance node, the system design node, the asset management node, and the operation node for secondary market metering devices. These five nodes are responsible for collecting and managing information from different stages of the metering device lifecycle.

Second, the method specifies the information collection and storage methods. Various information collected from the five aspectsmanufacturing, construction and maintenance, system design, asset management, and operationis encrypted and stored as blocks in the corresponding nodes. Crucially, the patent emphasizes linking the blocks of the same metering device across all nodes, creating a complete and traceable data chain. This linkage ensures data integrity and consistency, preventing data loss and information silos.

Furthermore, the patent designs a data modification mechanism to further enhance system security and reliability. When any information (manufacturing, construction and maintenance, system design, asset, or operational information) of a metering device needs modification, the modified information is also encrypted and added as a block to the corresponding node. Simultaneously, this block is linked to the existing blocks of the metering device in other nodes. This addition and linkage ensure the traceability of data changes, preventing tampering and data falsification, thus guaranteeing data authenticity and integrity.

This blockchain-based method effectively solves the problems of data dispersion, high security risks, and low efficiency in traditional management models. It not only achieves comprehensive record-keeping and real-time tracking of information but also ensures data security and reliability, significantly improving management efficiency and providing strong technical support for the supervision and operation of secondary market metering devices.
