[0043] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0044] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0045] It should be noted that the user information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data used for analysis, data stored, data displayed, etc.) involved in this application are all information and data authorized by the user or fully authorized by all parties. Furthermore, the collection, use and processing of the relevant data must comply with relevant laws, regulations and standards, and corresponding operation entry points are provided for users to choose to authorize or refuse.

[0046] First, the technical terms used in this application will be explained:

[0047] Blockchain is a distributed ledger technology that records data in a decentralized, immutable, and traceable manner, ensuring data security and trustworthiness.

[0048] Substation equipment lifecycle management covers the entire process of substation equipment management from planning, procurement, installation and commissioning, operation and maintenance, overhaul to scrapping, aiming to improve the reliability of substation equipment, reduce costs and optimize resource allocation.

[0049] Smart contracts are automated scripts that run on a blockchain and can be executed automatically based on preset conditions to automate device management business logic.

[0050] Hash algorithms are used to compress messages of arbitrary length into fixed-length hash values. They are used to verify the integrity and consistency of data and to identify data blocks and transactions in blockchains.

[0051] Zero-knowledge proof is a cryptographic technique that allows a prover to convince a verifier that a statement is true without providing the verifier with any useful information. In this application embodiment, it is used to protect the privacy of sensitive data.

[0052] Sidechain technology is a technology that connects the main chain with other blockchains, enabling asset transfer and data interaction between different blockchains. In this embodiment, sidechain technology is used to extend the main chain's functionality and achieve efficient processing in specific business scenarios.

[0053] In power systems, substation equipment serves as a crucial link in power transmission and distribution, and its full lifecycle management is essential for ensuring the stability and reliability of power supply. With the rapid development of the power industry, the number of substation equipment is constantly increasing, and the complexity and technological sophistication of this equipment are also rising. Traditional substation equipment management models suffer from numerous problems, such as fragmented data, severe information silos, insufficient data security and reliability, and cumbersome and inefficient management processes.

[0054] In terms of data management, data from various stages of substation equipment planning, procurement, and operation and maintenance are often stored in different systems or departments, lacking effective integration and sharing. For example, equipment procurement contract information is managed by the procurement department, while equipment operation data is recorded by the operation and maintenance department. This makes it difficult for different departments to obtain comprehensive equipment information in real time, affecting the accuracy and timeliness of equipment management decisions. At the same time, data security and reliability are difficult to guarantee. Traditional centralized data storage methods are vulnerable to network attacks, data tampering, and loss. Once data leakage or damage occurs, it will seriously affect the normal operation of substation equipment and the security of the power system. Traditional equipment management processes rely heavily on manual operations, resulting in cumbersome processes and low efficiency. For example, equipment maintenance applications require approval from multiple departments, which is time-consuming and may lead to equipment failures not being handled in a timely manner, increasing the risk of equipment failure and the operating costs of the power system.

[0055] Currently, information management systems based on relational databases are commonly used to manage substation equipment. These systems manage information at various stages of substation equipment management through different modules, such as equipment ledger modules, operation monitoring modules, maintenance management modules, and scrapping management modules. Specifically, the equipment ledger module stores basic equipment information, including equipment name, model, serial number, purchase date, and installation location; the operation monitoring module collects real-time operating data such as voltage, current, and temperature and stores the data in the database; the maintenance management module records maintenance requests, processes, and results; and the scrapping management module manages scrapping requests, approvals, and processing records. These modules interact through database relationships. For example, the maintenance management module associates its data with the equipment ledger module via the equipment serial number to obtain basic equipment information; similarly, the operation monitoring module associates its data with the equipment ledger module via the equipment serial number to match operational data with the equipment. However, this method of managing substation equipment suffers from poor data correlation and untimely data updates, leading to data conflicts and inconsistencies, as each module maintains its data independently. For example, discrepancies between the actual operating status of equipment and the records can complicate decision-making for maintenance personnel. After equipment repairs, maintenance records may not be promptly updated in the equipment ledger, resulting in inaccurate equipment status information and impacting maintenance personnel's assessments and decisions. Furthermore, the security of the information management system relies heavily on the security of the central database. If the database is attacked, data can easily be tampered with or leaked, severely affecting the management of substation equipment. In addition, the information management system has poor scalability, making it difficult to quickly adapt to new management needs as the number of devices increases and business requirements change.

[0056] With the rise of blockchain technology, its applications in various fields have gradually gained attention. The decentralized, immutable, and traceable characteristics of blockchain offer new ideas and methods for solving problems in the full lifecycle management of substation equipment. Among related technologies, blockchain can be applied to substation equipment data storage, primarily enabling the on-chain storage of substation equipment operation data. However, other aspects of substation equipment management, such as procurement, maintenance, and scrapping, still rely on traditional management methods, failing to achieve automation and process optimization for the entire lifecycle management of substation equipment. Furthermore, due to the lack of comprehensive integration of equipment management processes, the value of data is not fully realized, failing to provide strong support for equipment management decisions.

[0057] To address the aforementioned issues, this application provides a blockchain-based substation equipment lifecycle management system and method. Utilizing blockchain technology, it constructs a secure, efficient, and intelligent substation equipment lifecycle management system covering the entire process of substation equipment management, from planning, procurement, installation, commissioning, operation, maintenance, overhaul to scrapping. This enables real-time sharing, tamper-proofing, and traceability of substation equipment data, optimizes substation equipment management processes, improves management efficiency, reduces management costs, and effectively ensures the stable operation of substation equipment, thereby contributing to improved overall power system reliability.

[0058] The following section provides examples illustrating the application scenarios of the solution provided in this application.

[0059] Figure 1 This is a schematic diagram illustrating an application scenario provided by an embodiment of this application. For example... Figure 1 As shown, in this application scenario, the procurement department, manufacturer, installation and commissioning team, operation and maintenance department, repair department, and scrap disposal unit of substation equipment can be used as nodes of the blockchain to build a blockchain network. The nodes cooperate with each other to perform full life cycle management of substation equipment through the blockchain-based substation equipment full life cycle management system provided in this application embodiment.

[0060] It should be noted that, Figure 1 This is merely a schematic diagram illustrating one application scenario provided by an embodiment of this application. This embodiment does not necessarily represent... Figure 1 The nodes of the blockchain network included in it are limited.

[0061] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0062] Figure 2 This is a schematic diagram of a blockchain-based substation equipment lifecycle management system provided as an embodiment of this application. Figure 2 As shown, the blockchain-based substation equipment lifecycle management system 200 of this application embodiment includes:

[0063] The Equipment Planning and Procurement Module 201 is used to manage the creation, approval, and execution processes of procurement orders for substation equipment based on procurement smart contracts, and to store procurement information on the blockchain.

[0064] The equipment installation and commissioning module 202 is used to store the installation and commissioning information of substation equipment to the blockchain based on the installation and commissioning smart contract.

[0065] The equipment operation and maintenance module 203 is used to monitor the operation data of substation equipment, store the operation data in the blockchain, and determine whether the substation equipment needs maintenance based on the operation and maintenance smart contract, operation data and preset information; if so, it triggers the maintenance task and stores the maintenance information in the blockchain.

[0066] The equipment maintenance and update module 204 is used to manage the maintenance application, approval and execution process of substation equipment based on maintenance smart contracts, store maintenance information to the blockchain, and / or, in response to update instructions for substation equipment, update substation equipment based on update smart contracts and store update information to the blockchain.

[0067] The equipment scrapping module 205 is used to manage the application, approval and processing of substation equipment scrapping based on scrapping smart contracts, and to store equipment scrapping information to the blockchain.

[0068] In this embodiment, blockchain is used for the full lifecycle management of substation equipment, covering the entire process from planning, procurement, installation and commissioning, operation and maintenance, overhaul to scrapping. Optionally, the blockchain network is a consortium blockchain network, consisting of multiple nodes. These nodes include at least the substation equipment manufacturer, procurement department, installation and commissioning team, operation and maintenance department, overhaul department, and scrapping unit. The nodes communicate with each other through an encrypted communication protocol.

[0069] For example, in this embodiment, the blockchain network is a pre-built consortium blockchain network that can integrate various participating nodes in the full lifecycle management of substation equipment. Accordingly, the participating nodes in the blockchain network include at least the substation equipment manufacturer, procurement department, installation and commissioning team, operation and maintenance department, repair department, and scrapping unit, and may also include power regulatory departments, etc. The nodes communicate with each other through an encrypted communication protocol to jointly maintain the operation of the blockchain. Optionally, corresponding blockchain access permissions can be assigned to each node.

[0070] Understandably, the immutability and encrypted storage characteristics of blockchain can ensure the security and trustworthiness of data throughout the entire lifecycle of substation equipment. Once data is on the blockchain, it cannot be tampered with, guaranteeing its authenticity and integrity. Participating nodes can trust the data on the blockchain, avoiding the risk of malicious tampering or forgery, and providing reliable data support for substation equipment management decisions. Furthermore, the blockchain network enables real-time sharing of substation equipment data, breaking down information silos. Participating nodes can obtain the latest information on substation equipment in real time, collaborating on substation equipment management. For example, the operation and maintenance department can understand the procurement, installation, and commissioning information of substation equipment in real time, making advance preparations for operation and maintenance; the maintenance department can formulate more reasonable maintenance plans based on the operation and maintenance records of substation equipment, improving the efficiency and collaboration of substation equipment management.

[0071] Optionally, the blockchain network uses the Practical Byzantine Fault Tolerance (PBFT) consensus algorithm as the consensus mechanism among nodes.

[0072] It is understandable that adopting the PBFT consensus algorithm can ensure the efficiency and consistency of the blockchain network, enabling nodes in the blockchain network to quickly reach a consensus, guaranteeing reliable data storage and effective transaction execution. For example, suppose the procurement department initiates an equipment procurement process. The procurement department, as the requesting master node, broadcasts the equipment procurement message to other nodes. Correspondingly, the nodes corresponding to other departments can receive the equipment procurement message, verify its integrity and validity—for example, by checking the signature and sequence number of the message to ensure it has not been tampered with. After successful verification, they send a broadcast message to other nodes to confirm that a consensus has been reached on the equipment procurement message.

[0073] Optionally, the blockchain can use sidechain technology to process the target task and synchronize the processing results from the sidechain to the main chain.

[0074] For example, in scenarios with high real-time requirements or specific business processes, such as emergency maintenance procedures for substation equipment, rapid processing can be performed on a blockchain sidechain, and the results can be synchronized from the sidechain to the main chain. This ensures that the stability of the main chain is not affected while improving the processing efficiency of specific business processes. By introducing sidechain technology, the depth and breadth of blockchain applications can be effectively expanded.

[0075] In this embodiment, the blockchain smart contracts include procurement smart contracts, installation and commissioning smart contracts, operation and maintenance smart contracts, overhaul smart contracts, update smart contracts, and scrapping smart contracts. These are used to automate and optimize various business processes throughout the entire lifecycle management of substation equipment, improving management efficiency and decision-making accuracy. Automated execution of smart contracts reduces human intervention and optimizes substation equipment management processes. For example, based on procurement smart contracts, the approval and execution processes of purchase orders can be automatically executed, reducing human intervention and improving procurement efficiency. Based on operation and maintenance smart contracts, maintenance tasks can be automatically triggered according to substation equipment operation data, enabling preventative maintenance of substation equipment, reducing equipment failure rates, and improving equipment reliability and availability.

[0076] Specifically, the equipment planning and procurement module 201 can manage the creation, approval, and execution processes of purchase orders for substation equipment based on procurement smart contracts, and store procurement information on the blockchain. Optionally, the procurement information includes order information, equipment production information, and delivery information. The equipment planning and procurement module 201 can be specifically used to: in response to a purchase order creation instruction for substation equipment, obtain order information and upload it to the blockchain; in response to a submission instruction for equipment production information corresponding to a purchase order, obtain equipment production information and store it on the blockchain; and in response to a submission instruction for delivery information corresponding to a purchase order, obtain delivery information and store it on the blockchain.

[0077] For example, the procurement department in the blockchain formulates an equipment procurement plan based on the substation's needs and creates purchase orders through a procurement smart contract. Correspondingly, the equipment planning and procurement module 201 responds to the instruction to create a purchase order for substation equipment, obtains the order information, and uploads it to the blockchain, effectively putting the order information on the chain. The procurement smart contract automatically notifies the manufacturer in the blockchain. Upon receiving the purchase order, the manufacturer confirms it and uploads the equipment production and delivery information to the chain. This allows the procurement department to query the order status and equipment production progress in real time. During the procurement process, the procurement smart contract automatically executes the payment process according to preset conditions, ensuring transparency and traceability. The traceability of the blockchain can be used to track information such as the source of raw materials and the production process of the equipment, ensuring equipment quality.

[0078] Optionally, when the equipment planning and procurement module 201 is used to store procurement information to the blockchain, it can specifically be used to: encrypt sensitive information in the procurement information using zero-knowledge proof technology to obtain encrypted sensitive information; and store the encrypted sensitive information to the blockchain for verification and execution of transactions corresponding to the procurement order.

[0079] For example, if the procurement information contains sensitive information, such as procurement prices, zero-knowledge proof technology can be used to verify and execute transactions without disclosing specific data, thus protecting corporate trade secrets. Zero-knowledge proof technology can protect the privacy and security of sensitive information (data), helping to expand the depth and breadth of blockchain applications.

[0080] The equipment installation and commissioning module 202 can store substation equipment installation and commissioning information on the blockchain based on an installation and commissioning smart contract. Specifically, after receiving the equipment, the installation and commissioning team on the blockchain records installation and commissioning information such as installation time, installers, and commissioning results through the installation and commissioning smart contract. After the equipment installation and commissioning are completed, the installation and commissioning information is uploaded to the blockchain, and the maintenance department on the blockchain is notified that the equipment is ready for use. Simultaneously, key data during the installation and commissioning process can be encrypted and stored through the installation and commissioning smart contract to ensure data security. Correspondingly, the maintenance department can obtain the equipment installation and commissioning information through the blockchain to prepare for subsequent maintenance work. Furthermore, the installation and commissioning team can utilize equipment design drawings and technical specifications on the blockchain to ensure the accuracy of the installation and commissioning work.

[0081] The equipment operation and maintenance module 203 monitors the operating data of substation equipment, stores the operating data on the blockchain, and determines whether the substation equipment needs maintenance based on the operation and maintenance smart contract, operating data, and preset information. If so, it triggers a maintenance task and stores the maintenance information on the blockchain. The preset information includes preset thresholds and preset rules. Specifically, during the operation of substation equipment, for example, the equipment operation and maintenance module can collect operating data in real time through sensors, including data such as voltage, current, and temperature, and upload this data to the blockchain. The module can automatically determine whether substation equipment needs maintenance based on the operating data, preset thresholds, and preset rules, according to the operation and maintenance smart contract. For example, when the temperature of the substation equipment exceeds a preset threshold, the operation and maintenance smart contract can automatically trigger a maintenance task, notifying maintenance personnel in the blockchain to inspect and maintain the equipment, recording the maintenance process, and storing the maintenance information (maintenance result) on the blockchain. Through real-time monitoring and analysis of substation equipment operating data, potential equipment problems can be identified promptly, and corresponding measures can be taken to ensure the stable operation of the equipment. Optionally, based on operation and maintenance smart contracts, big data analytics can be used to conduct in-depth analysis of the operating data of substation equipment, predict potential equipment failures in advance, and achieve preventative maintenance.

[0082] The equipment maintenance and upgrade module 204 is used to manage the application, approval, and execution processes for substation equipment maintenance based on maintenance smart contracts. It stores maintenance information on the blockchain and / or, in response to upgrade instructions for substation equipment, updates the substation equipment based on upgrade smart contracts and stores the update information on the blockchain. Specifically, when substation equipment malfunctions or reaches its maintenance cycle, the maintenance department in the blockchain can initiate a maintenance application through the equipment maintenance and upgrade module based on the maintenance smart contract. The application is approved based on the equipment's operating history and maintenance plan, and maintenance is carried out after approval. After maintenance is completed, maintenance records and information on replaced parts are stored on the blockchain based on the maintenance smart contract. Automated execution of maintenance smart contracts reduces human intervention and improves the efficiency and accuracy of the maintenance process. If equipment needs to be upgraded, the decision-making and execution of equipment upgrades can be made through upgrade smart contracts, ensuring reasonable asset allocation, and the update information is stored on the blockchain. The equipment operation data and maintenance information on the blockchain can provide a basis for decision-making regarding equipment upgrades, selecting the most suitable equipment for upgrades.

[0083] The equipment scrapping module 205 manages the application, approval, and processing of substation equipment scrapping based on a scrapping smart contract, and stores equipment scrapping information on the blockchain. Specifically, when substation equipment reaches the end of its service life or is beyond repair, the scrapping unit in the blockchain can initiate a scrapping application through the module based on the smart contract. After approval by the smart contract, the equipment is scrapped. Scrapping methods, recycling value, and other equipment scrapping information are recorded on the blockchain, and relevant departments are notified for asset write-off, achieving effective asset management. Simultaneously, relevant data on scrapped equipment is archived (i.e., permanently stored) to facilitate subsequent auditing and analysis, and to provide data support for subsequent environmental assessments and resource recycling.

[0084] It is understandable that the blockchain stores various types of data throughout the entire lifecycle of substation equipment, including basic equipment information, procurement information (such as purchase contracts), installation and commissioning information, substation equipment operation data, maintenance information, update information, and equipment scrapping information. The data is stored in encrypted form, and hash algorithms ensure its integrity and immutability. Nodes in the blockchain interact with each other through the blockchain network, achieving real-time data sharing and synchronization. Distributed storage technology is used to distribute data across various nodes, improving data storage security and availability.

[0085] The blockchain-based substation equipment lifecycle management system provided in this application includes: an equipment planning and procurement module that manages the creation, approval, and execution of substation equipment purchase orders based on procurement smart contracts, storing procurement information on the blockchain; an equipment installation and commissioning module that stores substation equipment installation and commissioning information on the blockchain based on installation and commissioning smart contracts; an equipment operation and maintenance module that monitors substation equipment operation data, stores operation data on the blockchain, and determines whether substation equipment needs maintenance based on operation and maintenance smart contracts, operation data, and preset information; if so, it triggers a maintenance task and stores maintenance information on the blockchain; and an equipment inspection and renewal module that manages the application, approval, and execution processes for substation equipment inspection based on inspection smart contracts. The system stores maintenance information on the blockchain and / or, in response to update instructions for substation equipment, updates the substation equipment based on update smart contracts and stores the update information on the blockchain. The equipment scrapping module, based on scrapping smart contracts, manages the application, approval, and processing of substation equipment scrapping and stores the equipment scrapping information on the blockchain. This enables secure, efficient, and intelligent full lifecycle management of substation equipment based on blockchain, achieving real-time sharing, immutability, and traceability of substation equipment data. This improves data security and reliability, optimizes the management process of substation equipment, increases management efficiency, reduces management costs, and ensures stable operation of substation equipment, thereby contributing to the overall reliability of the power system.

[0086] Based on the above embodiments, Figure 3 The flowchart illustrates a blockchain-based substation equipment lifecycle management method provided in one embodiment of this application, applicable to the blockchain-based substation equipment lifecycle management system as described in any of the above embodiments. Figure 3 As shown, the method in this application embodiment includes:

[0087] S301, the Equipment Planning and Procurement module, is based on procurement smart contracts. It manages the creation, approval, and execution processes of procurement orders for substation equipment and stores procurement information on the blockchain.

[0088] In this step, the equipment planning and procurement module can manage the creation, approval, and execution of purchase orders for substation equipment based on procurement smart contracts, and store procurement information on the blockchain. Optionally, the procurement information includes order information, equipment production information, and delivery information. In response to a purchase order creation instruction for substation equipment, the equipment planning and procurement module obtains the order information and uploads it to the blockchain; in response to a submission instruction for equipment production information corresponding to a purchase order, it obtains the equipment production information and stores it on the blockchain; and in response to a submission instruction for delivery information corresponding to a purchase order, it obtains the delivery information and stores it on the blockchain.

[0089] For example, the procurement department in the blockchain formulates an equipment procurement plan based on the substation's needs and creates purchase orders through a procurement smart contract. Correspondingly, the equipment planning and procurement module responds to the instruction to create a purchase order for substation equipment, obtains the order information, and uploads it to the blockchain, effectively putting the order information on the chain. The procurement smart contract automatically notifies the manufacturer in the blockchain. Upon receiving the purchase order, the manufacturer confirms it and uploads the equipment production and delivery information to the chain through the procurement smart contract. This allows the procurement department to query the order status and equipment production progress in real time. During the procurement process, the procurement smart contract automatically executes the payment process according to preset conditions, ensuring transparency and traceability. The traceability of the blockchain can be used to track information such as the source of raw materials and the production process of the equipment, ensuring equipment quality.

[0090] Optionally, when the equipment planning and procurement module is used to store procurement information on the blockchain, it can be specifically used to: encrypt sensitive information in the procurement information using zero-knowledge proof technology to obtain encrypted sensitive information; and store the encrypted sensitive information on the blockchain for verification and execution of transactions corresponding to the procurement order.

[0091] S302. The equipment installation and commissioning module stores the installation and commissioning information of substation equipment to the blockchain based on the installation and commissioning smart contract.

[0092] For example, upon receiving the equipment, the installation and commissioning team in the blockchain records installation and commissioning information such as installation time, installers, and commissioning results through the equipment installation and commissioning module based on an installation and commissioning smart contract. After installation and commissioning are completed, the team uploads this information to the blockchain and notifies the maintenance department in the blockchain that the equipment is ready for use. Simultaneously, the equipment installation and commissioning module can encrypt and store key data during the installation and commissioning process based on the installation and commissioning smart contract to ensure data security. Correspondingly, the maintenance department can access the equipment installation and commissioning information through the blockchain to prepare for subsequent maintenance work. Furthermore, the installation and commissioning team can utilize equipment design drawings and technical specifications on the blockchain to ensure the accuracy of the installation and commissioning work.

[0093] S303 The equipment operation and maintenance module monitors the operation data of substation equipment, stores the operation data in the blockchain, and determines whether the substation equipment needs maintenance based on the operation and maintenance smart contract, operation data and preset information; if so, it triggers the maintenance task and stores the maintenance information in the blockchain.

[0094] For example, the preset information includes preset thresholds and preset rules. During the operation of substation equipment, for instance, the equipment operation and maintenance module can collect real-time operating data from sensors, including data such as voltage, current, and temperature, and upload this data to the blockchain. The equipment operation and maintenance module can then automatically determine whether substation equipment requires maintenance based on the operating data, preset thresholds, and preset rules, using an operation and maintenance smart contract. For example, when the temperature of substation equipment exceeds a preset threshold, the operation and maintenance smart contract can automatically trigger a maintenance task, notifying maintenance personnel in the blockchain's operations and maintenance department to inspect and maintain the equipment, recording the maintenance process, and storing the maintenance information (maintenance results) on the blockchain. Through real-time monitoring and analysis of substation equipment operating data, potential equipment problems can be identified promptly, and corresponding measures can be taken to ensure the stable operation of the equipment.

[0095] S304. The equipment maintenance and update module manages the maintenance application, approval and execution process of substation equipment based on maintenance smart contracts, stores maintenance information on the blockchain, and / or updates the substation equipment based on update smart contracts in response to update instructions for substation equipment.

[0096] For example, when substation equipment malfunctions or reaches its maintenance cycle, the maintenance department in the blockchain can initiate a maintenance application based on a maintenance smart contract through the equipment maintenance and upgrade module. The smart contract approves the application based on the equipment's operating history and maintenance plan, and maintenance is carried out after approval. After maintenance, maintenance information, such as maintenance records and information on replaced parts, is stored on the blockchain based on the smart contract. Automated execution of the maintenance smart contract reduces human intervention and improves the efficiency and accuracy of the maintenance process. If equipment needs to be upgraded, the decision-making and execution of equipment upgrades can be made through an upgrade smart contract, ensuring reasonable asset allocation, and the upgrade information is stored on the blockchain. The equipment operation data and maintenance information on the blockchain can provide a basis for decision-making regarding equipment upgrades, selecting the most suitable equipment for upgrades.

[0097] S305, the equipment scrapping module, is based on a scrapping smart contract to manage the application, approval and processing of scrapping of substation equipment and to store equipment scrapping information on the blockchain.

[0098] For example, when substation equipment reaches the end of its service life or is beyond repair, the scrapping unit in the blockchain can initiate a scrapping application based on a scrapping smart contract through the equipment scrapping module. After approval by the smart contract, the equipment is scrapped. Information regarding the scrapping process, including the scrapping method and recycling value, is recorded on the blockchain, and relevant departments are notified to perform asset write-offs, achieving effective asset management. Simultaneously, relevant data on the scrapped equipment is archived (i.e., permanently stored) to facilitate subsequent auditing and analysis, and to provide data support for subsequent environmental assessments and resource recycling.

[0099] Optionally, the blockchain network is a consortium blockchain network, consisting of multiple nodes. These nodes include at least the substation equipment manufacturer, procurement department, installation and commissioning team, operation and maintenance department, repair department, and scrap disposal unit. The nodes communicate with each other through an encrypted communication protocol.

[0100] Optionally, the blockchain network uses the Practical Byzantine Fault-Tolerant (PBFT) consensus algorithm as the consensus mechanism among nodes.

[0101] Optionally, the blockchain can use sidechain technology to process the target task and synchronize the processing results from the sidechain to the main chain.

[0102] The blockchain-based substation equipment lifecycle management method provided in this application is applied to the blockchain-based substation equipment lifecycle management system as described in any of the above embodiments. The equipment planning and procurement module manages the creation, approval, and execution of substation equipment purchase orders based on procurement smart contracts, storing procurement information on the blockchain. The equipment installation and commissioning module stores substation equipment installation and commissioning information on the blockchain based on installation and commissioning smart contracts. The equipment operation and maintenance module monitors substation equipment operation data, stores operation data on the blockchain, and determines whether substation equipment requires maintenance based on operation and maintenance smart contracts, operation data, and preset information. If so, a maintenance task is triggered, and maintenance information is stored on the blockchain. The equipment inspection and renewal module manages the substation equipment lifecycle management system based on inspection smart contracts. The maintenance application, approval, and execution process for substation equipment stores maintenance information on the blockchain, and / or, in response to update instructions for substation equipment, updates the substation equipment based on update smart contracts and stores the update information on the blockchain. The equipment scrapping module, based on scrapping smart contracts, manages the scrapping application, approval, and processing process for substation equipment and stores equipment scrapping information on the blockchain. This enables secure, efficient, and intelligent full lifecycle management of substation equipment based on blockchain, achieving real-time sharing, immutability, and traceability of substation equipment data. This improves data security and reliability, optimizes substation equipment management processes, increases management efficiency, reduces management costs, and ensures stable operation of substation equipment, thereby contributing to improved overall reliability of the power system.
