Description

Technical Field

[0001] This application relates to the fields of industrial internet and information security technology, and in particular to a method, apparatus, computer equipment, computer-readable storage medium, and computer program product for processing information on power equipment. Background Technology

[0002] In the field of industrial internet and information security, traditional power equipment information processing usually adopts a centralized storage model. For example, transformer operating status data is centrally stored on a central server, while full life cycle data is scattered in the systems of different entities such as manufacturers and maintenance providers. Moreover, data security mainly relies on the firewall and access control of the central database.

[0003] However, with this traditional approach, the original information of power equipment is easily tampered with, forged, or deleted, and it is difficult to integrate and share. This results in poor continuity of equipment files, low traceability efficiency, and affects the detection and management of power equipment. Moreover, information security is highly dependent on the protection of the central node. Once the central node is breached, it can easily lead to large-scale information leakage. At the same time, maintenance records can be modified, and there is human intervention in the process, resulting in low transparency and credibility of the maintenance process.

Leveraging the immutability and traceability of the blockchain, it ensures that the original information of the power equipment cannot be arbitrarily modified or forged once it is on the chain. Furthermore, it adopts a distributed architecture of "local / external storage + blockchain evidence storage," reducing the security dependence on a single central node and solving the problem of data tampering and deletion in traditional centralized storage, thereby improving data credibility and long-term authenticity. On the other hand, by combining digital twin archives with blockchain evidence storage information, this application can reliably integrate data from all stages of equipment operation, maintenance, and operation triggering, forming a continuous and complete equipment archive.

[0048] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0049] It should be noted that the terms "first," "second," etc., used in this application can be used to describe various objects, but these objects are not limited by these terms. These terms are only used to distinguish the first object from the second object. The term "comprising" and any variations thereof, as used in this application, are intended to cover non-exclusive inclusion. The term "multiple" as used in this application refers to two or more. The term "and / or" as used in this application refers to one of the solutions, or any combination of multiple solutions.

[0050] The power equipment information processing method provided in this application embodiment can be applied to, for example, Figure 1The application environment is illustrated. The perception layer can communicate with the edge processing layer, which in turn can communicate with the peripheral storage layer and the blockchain layer. The blockchain layer can communicate with the application service layer. The perception layer can consist of various sensing devices deployed on the physical entity of the power equipment; these devices collect real-time operational status data. The edge processing layer can incorporate edge intelligent terminals, which are responsible for initial data processing, hash calculation, transaction construction, and signature issuance. The peripheral storage layer can employ distributed storage systems (such as IPFS (InterPlanetary File System)) or cloud storage, and can also integrate storage protocols (such as the Filecoin incentive layer protocol) and data processing technologies (such as data compression); it stores the raw data collected by the sensing devices. The application service layer provides interfaces for different user roles (such as maintenance engineers, managers, and auditors) to view data, query evidence, receive alarm notifications, and manage identities. The blockchain layer, which can be built on a consortium blockchain, is fundamentally based on a blockchain network. This layer can include a peer-to-peer network, a distributed ledger, and a smart contract engine. The peer-to-peer network can be maintained by multiple authorized participating nodes (such as manufacturers, operators, and regulatory agencies). The distributed ledger records all notarized transactions (such as data hashes, digital identities, and contract logs). The smart contract engine is responsible for parsing and executing on-chain business logic.

[0051] In one exemplary embodiment, such as Figure 2 As shown, a method for processing information about power equipment is provided, which can be applied to... Figure 1 In the edge processing layer of a process, the method may include the following steps:

[0052] Step 201: In response to the operating status information of the power equipment collected by the sensing device, obtain the first hash value of the operating status information, and store the operating status information to the local storage system and / or the external storage layer.

[0053] Among these, "operational status information" refers to data / information that reflects the operating status of power equipment. The first hash value can be a data digest obtained by performing a hash operation on the operational status information. The local storage system can refer to the local storage of the edge intelligent terminal built into the edge processing layer.

[0054] For example, the operating status information of power equipment is collected through various sensing devices included in the perception layer; a first hash value is obtained by hashing the operating status information of the power equipment using a cryptographic hash function; and the operating status information of the power equipment can be stored in the local storage system and / or peripheral storage layer of the edge intelligent terminal. The sensing devices included in the perception layer can form a sensing device cluster.

[0055] Step 202: Send the second hash value of the first evidence storage information to the blockchain layer; the first evidence storage information includes the first hash value and the acquisition time of the operating status information; the second hash value is used by the blockchain layer to obtain the operating status information and trigger the operation on the power equipment through the smart contract engine when the operating status information meets the operation triggering conditions.

[0056] The first piece of evidence information can refer to a data unit / combined data packet generated by combining the first hash value and the collection time of the operating status information. The collection time of the operating status information can refer to the moment when the operating status information is collected; the collection time can be a collection timestamp. The second hash value can be a data digest / signature obtained by hashing the first piece of evidence information. The operation triggering condition can refer to the conditions that the operating status information must meet when an operation on the power equipment is triggered by the smart contract engine. The smart contract engine can be a component built into the blockchain layer.

[0057] For example, the edge processing layer combines the first hash value and the acquisition time of the operating status information to generate first evidence information, performs a hash operation on the first evidence information to obtain a second hash value of the first evidence information, and sends the second hash value to the blockchain layer. In response to the receipt of the second hash value, the blockchain layer retrieves the first evidence information based on the second hash value, retrieves the operating status information of the power equipment based on the first hash value contained in the first evidence information, and triggers operations on the power equipment (such as sending trusted alarms to responsible personnel, generating and registering maintenance tasks, and initiating trusted business processes with collaborators (such as insurance claims)) through the smart contract engine when the operating status information meets the operation triggering conditions (e.g., oil temperature exceeding a set limit and the duration reaching a threshold).

[0058] In one specific implementation, a smart contract engine can be formed by deploying smart contracts with business logic on the blockchain.

[0059] In this embodiment, trusted data such as the first hash value and the second hash value are used to automate and trustlessly execute business logic.

[0060] Step 203: Determine the digital twin file of the power equipment based on the second evidence information corresponding to the operation of the power equipment and the digital twin of the power equipment.

[0061] The second type of evidence can refer to evidence related to the operation of electrical equipment. A digital twin can refer to a complete, tamper-proof, and reliable record of the electrical equipment.

[0062] For example, the second evidence information corresponding to the operation of the power equipment is associated with the digital twin of the power equipment for evidence storage, thereby obtaining the digital twin file of the power equipment.

[0063] In the aforementioned power equipment information processing method, in response to the operating status information of the power equipment collected by the sensing device, a first hash value of the operating status information is obtained, and the operating status information is stored in a local storage system and / or an external storage layer. A second hash value of the first evidence information is sent to the blockchain layer. The first evidence information includes the first hash value and the time of collection of the operating status information. The second hash value is used by the blockchain layer to obtain the operating status information and, when the operating status information meets the operation triggering conditions, to trigger an operation on the power equipment through a smart contract engine. Based on the second evidence information corresponding to the operation on the power equipment and the digital twin of the power equipment, a digital twin file of the power equipment is determined. Compared to traditional technologies, this embodiment, on the one hand, uploads the hash value and evidence information of the operating status information to the blockchain layer. Leveraging the immutability and traceability of the blockchain, it ensures that the original information of the power equipment cannot be arbitrarily modified or forged once it is on the chain. Furthermore, it adopts a distributed architecture of "local / external storage + blockchain evidence storage," reducing the security dependence on a single central node and solving the problem of data tampering and deletion in traditional centralized storage, thereby improving data credibility and long-term authenticity. On the other hand, this embodiment, through digital twin archives combined with blockchain evidence storage information, can reliably link and integrate data from all stages of equipment operation, maintenance, and operation triggering, forming a continuous and complete equipment archive. This provides a complete and reliable data view for equipment detection, management, and historical traceability. Moreover, this embodiment uses a smart contract engine to automatically trigger operations on the power equipment based on the operating status information, reducing manual intervention and preventing the possibility of arbitrary modification of maintenance records. All secondary evidence storage information corresponding to operations is stored on the blockchain, making the entire operation process traceable and tamper-proof, significantly improving the transparency and credibility of the maintenance process.

[0064] In one exemplary embodiment, before sending the second hash value of the evidence storage information to the blockchain layer, the method further includes:

[0065] Obtain the first device identification information, the device attribute information, and the third hash value of the device attribute information of the power equipment; write the first device identification information, the device attribute information, and the third hash value into the blockchain layer.

[0066] The first device identification information can refer to the distributed digital identity identifier (such as DID, or Decentralized Identifier) ​​of the power equipment; this information is globally unique. The device attribute information can refer to information reflecting the key attributes of the power equipment (such as model, serial number, and technical specifications). The third hash value can be a digital digest obtained by performing a hash operation on the device attribute information.

[0067] For example, for each piece of electrical equipment leaving the factory, a first equipment identification information is generated for the electrical equipment. The first equipment identification information, the equipment attribute information, and the third hash value of the equipment attribute information are written into the blockchain layer as initial evidence to complete the trusted digital mapping registration of the electrical equipment on the blockchain.

[0068] In one exemplary embodiment, the first evidence storage information further includes second device identification information of the power equipment and third device identification information of the sensing device;

[0069] The second hash value of the first evidence storage information sent to the blockchain layer includes:

[0070] The notarization transaction carrying the second hash value is broadcast to the blockchain network; the blockchain layer is used to obtain the second hash value through the blockchain network, obtain the second device identification information and the third device identification information based on the second hash value, and perform consensus verification on the notarization transaction based on the comparison between the second device identification information and the first device identification information, the third device identification information, and the comparison between the fourth hash value and the third hash value. If the notarization transaction passes the verification, the second hash value is written into the distributed ledger of the blockchain layer; the fourth hash value is obtained by hashing the device attribute information through the blockchain layer.

[0071] The first evidence information can refer to evidence data units / combined data packets generated by combining the first hash value, the collection time of the operating status information, the second equipment identification information of the power equipment, and the third equipment identification information of the sensing device.

[0072] For example, the first hash value, the collection time of the operating status information, the second device identification information of the power equipment, and the third device identification information of the sensing device are combined to generate the first evidence storage information; a hash operation is performed on the first evidence storage information to obtain the second hash value of the first evidence storage information; the evidence storage transaction containing the second hash value is submitted to the blockchain network via broadcast; the blockchain layer is used by nodes of the blockchain network to obtain the second device identification information and the third device identification information based on the second hash value, compare the second device identification information with the first device identification information to verify the identity of the power equipment, verify whether the sensing device is authorized to collect data based on the third device identification information, and compare the fourth hash value with the third hash value to verify whether the device attribute information has been tampered with, thereby achieving consensus verification of the evidence storage transaction; if the evidence storage transaction passes verification, the second hash value is written into the distributed ledger of the blockchain layer. The blockchain layer responds to the receipt of the evidence storage transaction by returning a transaction receipt to the edge processing layer.

[0073] In this embodiment, the operational status information (i.e., raw monitoring information) collected by the sensing device is stored in the local storage system and / or the external storage layer (such as a distributed file system). Only a very small hash value is uploaded to the blockchain, which can greatly alleviate the storage pressure and transaction processing load of the blockchain. Moreover, based on the distributed ledger characteristics of the blockchain, once the second hash value is written into the distributed ledger of the blockchain layer, it will be synchronized to all nodes participating in the accounting in the network. To modify or delete the second hash value on the blockchain, it is necessary to attack and modify the data copies on most nodes around the world simultaneously. It can also be understood that as long as the blockchain network exists, the second hash value will be permanently stored on the blockchain.

[0074] In an exemplary embodiment, after determining the digital twin profile of the power equipment based on the second evidence information corresponding to the operation of the power equipment and the digital twin of the power equipment, the method further includes:

[0075] In response to an authorized user's request for access to runtime status information, the runtime status information stored in the local storage system is transmitted to the authorized user. The authorized user performs a hash operation on the received runtime status information to obtain a fifth hash value, retrieves a second hash value from the distributed ledger, and retrieves a first hash value based on the second hash value. The user compares the fifth hash value with the first hash value. If the fifth hash value matches the first hash value, it is determined that the runtime status information stored in the local storage system has not been tampered with. If the fifth hash value does not match the first hash value, it is determined that the runtime status information stored in the local storage system has been tampered with.

[0076] Authorized users can refer to participants who are granted rights / qualifications such as data access.

[0077] For example, an authorized user sends a signal to acquire operational status information through the application service layer. The edge intelligent terminal of the edge processing layer transmits the operational status information stored in the local storage system to the authorized user. After obtaining the operational status information of the power equipment collected by the sensing device from the local storage system, the authorized user performs a hash operation on the operational status information to obtain a fifth hash value. Simultaneously, the user obtains a second hash value from the distributed ledger and obtains a first hash value based on the second hash value. The fifth hash value is compared with the first hash value. If the fifth hash value and the first hash value match, it is determined that the operational status information stored in the local storage system has not been tampered with. If the fifth hash value and the first hash value do not match, it is determined that the operational status information stored in the local storage system has been tampered with.

[0078] In this embodiment, users can also collect raw operational data (such as the operating status information of power equipment collected by sensor devices) from the blockchain layer through components such as data viewing in the application service layer.

[0079] In one exemplary embodiment, the operation of the power equipment includes operations performed on the power equipment from commissioning to decommissioning; the second evidence includes the log hash value of the operation log, the file hash value of the operation report file, and the identity information of the executor of the operation.

[0080] Based on the second evidence storage information corresponding to the operation of the power equipment and the digital twin of the power equipment, a digital twin file of the power equipment is determined, including:

[0081] By associating and storing log hash values, file hash values, and identity information with the digital twin of the power equipment, a digital twin archive of the power equipment is obtained.

[0082] Operations related to power equipment can refer to actions performed on the equipment (such as installation, commissioning, periodic inspections, fault repair, component replacement, insulation testing, etc.). The process from commissioning to decommissioning of power equipment can refer to its entire lifecycle. Identification information can refer to the digital identity of the person performing the operation. A digital twin can be a trusted record of the entire lifecycle of the power equipment.

[0083] For example, for each operation performed on the power equipment from commissioning to decommissioning, the log hash value of the operation log, the file hash value of the operation report file, and the identity information of the executor of the operation are associated with and stored as a digital twin of the power equipment to obtain a digital twin file of the power equipment.

[0084] In one exemplary embodiment, the running status information includes multi-dimensional running status data; the method further includes:

[0085] The multidimensional operational status data is preprocessed to obtain preprocessed multidimensional operational status data; the preprocessing includes filtering and noise reduction.

[0086] The preprocessed multidimensional operating status data are sequentially fused and fault detected to obtain the fault detection results of the power equipment.

[0087] Multidimensional operating status data can refer to the operating status data of power equipment in multiple dimensions (such as oil temperature, load current, vibration and noise, and partial discharge).

[0088] For example, the multidimensional operating status data is preprocessed by filtering and noise reduction to obtain preprocessed multidimensional operating status data; the preprocessed multidimensional operating status data is then subjected to data fusion and fault detection to obtain the fault detection results of the power equipment.

[0089] Transformers are core electrical equipment in the power grid, and their operating status directly affects the grid's safety and stability. Currently, transformer monitoring mainly relies on various sensors and online monitoring systems, but these systems have significant shortcomings in terms of data reliability, information sharing, system security, and operation and maintenance efficiency.

[0090] Transformer monitoring data is typically stored on centralized servers or local devices, which are susceptible to tampering, falsification, or deletion. For example, in critical testing stages such as insulation resistance and dielectric loss testing, human intervention in the data could lead to misjudgments of equipment status, resulting in safety hazards. Furthermore, when equipment failures require tracing responsibility, the lack of third-party verification mechanisms for data storage makes it difficult to guarantee the authenticity and integrity of the data, easily leading to disputes.

[0091] Transformer lifecycle data covers multiple stages, including production, installation, operation and maintenance, and scrapping, and is scattered across the systems of different entities, such as manufacturers, maintenance providers, and power grid companies. Due to inconsistent data formats, information from each stage is difficult to integrate effectively, resulting in insufficient consistency and reliability of equipment records. Taking UHV transformer test data as an example, it needs to go through multiple stages of transfer; without a unified data management mechanism, traceability efficiency will be significantly reduced, affecting the accuracy of equipment quality control and fault diagnosis.

[0092] The security of existing monitoring systems heavily relies on the firewalls and access control of centralized databases. If the central node is attacked, all data is at risk of leakage and corruption. For example, security testing of toroidal transformers requires multi-dimensional data verification, but the singular nature of centralized storage makes it difficult to meet high security requirements. Furthermore, in the fault handling processes of equipment such as photovoltaic inverters, manual intervention can lead to response delays, and the modifiability of operation records reduces the transparency and credibility of the maintenance process.

[0093] Blockchain technology, with its decentralized, immutable, and traceable characteristics, offers potential solutions to the aforementioned problems. However, directly applying public blockchain technology to industrial IoT scenarios (such as transformer monitoring) still faces challenges in performance, privacy, and cost. Industrial equipment monitoring typically involves large volumes of data and requires high real-time performance, while traditional blockchain consensus mechanisms (such as PoW (Proof of Work) and PoS (Proof of Stake)) struggle to meet the demands for efficient processing. Furthermore, transformer data involves core asset information of power grid companies, necessitating a balance between data sharing and privacy protection. In addition, the deployment and maintenance costs of blockchain nodes are high, making them unsuitable for the actual needs of industrial scenarios.

[0094] In one exemplary embodiment, a power equipment information processing system is provided, the system comprising: as follows Figure 1 The layers shown are the perception layer, edge processing layer, peripheral storage layer, blockchain layer, and application service layer.

[0095] The edge processing layer is used to execute the steps of the power equipment information processing method as described in any of the above embodiments.

[0096] In this embodiment, a transformer is used as an example of power equipment for explanation. In this example, as... Figure 3 As shown, a transformer information processing method may include the following steps:

[0097] Step 301, Trusted Digital Identity Anchoring.

[0098] For example, a globally unique DID is generated for each transformer leaving the factory, and the DID, equipment attribute information (such as model, factory number, technical specifications) and digital digest of equipment attribute information are written into the blockchain as initial evidence to complete the trusted digital mapping registration of the equipment on the chain.

[0099] Step 302: Lightweight evidence storage of monitoring data.

[0100] For example, the operating status information of the transformer (such as oil temperature, load current, vibration noise, and partial discharge) is collected by the various sensors included in the sensor cluster built into the perception layer; the operating status information of the transformer is preprocessed by filtering and noise reduction through the edge intelligent terminal built into the edge processing layer, as well as data fusion and fault diagnosis, to obtain the first hash value (Hash1) of the operating status information of the transformer and store the operating status information of the transformer in the local storage system and / or the external storage layer; the Hash1, the timestamp of the collection of the operating status information, the DID of the transformer, and the identifier of the sensor device are combined to generate a notarized data unit, and the second hash value (Hash2) of the unit is calculated; the edge processing layer submits the notarized transaction containing Hash2 to the blockchain network by broadcasting; the blockchain layer is used to obtain Hash2 through the blockchain network, perform consensus verification of the notarized transaction based on Hash2, and write Hash2 into the distributed ledger of the blockchain layer if the notarized transaction passes verification.

[0101] Step 303: Full lifecycle time feasibility record.

[0102] For example, for every operation performed on the transformer from commissioning to decommissioning, the log hash value of the operation log, the file hash value of the operation report file, and the identity information of the executor of the operation are associated and stored with the digital twin of the transformer, forming a notarized record. Figure 4 The complete, tamper-proof, and trusted full lifecycle history is shown.

[0103] Step 304, Smart Contract-Driven Automatic Response.

[0104] For example, smart contracts with business logic are deployed on the blockchain to form a smart contract engine. When the data notarization received at the blockchain layer (such as the second hash value) meets the set operation triggering conditions (such as the oil temperature exceeding the set limit and the duration reaching the threshold), the smart contract engine triggers predefined operations (such as sending trusted alarms to responsible personnel, generating and registering maintenance tasks, and initiating trusted business processes with collaborators (such as insurance claims)).

[0105] Step 305: Data authenticity verification.

[0106] For example, such as Figure 5 As shown, data authenticity verification can be achieved through the following steps:

[0107] Step 501: Authorize the user to obtain the raw data.

[0108] For example, an authorized user sends a signal to acquire runtime status information through the application service layer, and the edge intelligent terminal of the edge processing layer transmits the runtime status information stored in the local storage system to the authorized user.

[0109] Step 502: Calculate Hash5.

[0110] For example, after an authorized user obtains the transformer's operating status information collected by the sensing device from the local storage system, the user performs a hash operation on the operating status information to obtain a fifth hash value (Hash5).

[0111] Step 503: Query the Hash2 stored on the blockchain.

[0112] For example, Hash2 is obtained from the distributed ledger and Hash1 is obtained based on Hash2.

[0113] Step 504: Compare whether the data are consistent.

[0114] For example, Hash5 is compared with Hash1 to determine whether they are the same.

[0115] Step 505: If the data is consistent, it indicates that the data is true and reliable.

[0116] For example, if Hash5 matches Hash1, it is determined that the running status information stored in the local storage system has not been tampered with, that is, the running status information obtained by the authorized user is true and reliable.

[0117] Step 506: If the data is inconsistent, it indicates that the data has been modified.

[0118] For example, if Hash5 and Hash1 do not match, it is determined that the runtime status information stored in the local storage system has been tampered with, that is, the runtime status information obtained by the authorized user has been modified.

[0119] In this embodiment, on the one hand, the power equipment information processing system leverages the immutability of blockchain to ensure the authenticity and integrity of all monitoring data and operation records. This provides credible evidence with legal force for accident accountability, quality traceability, and insurance claims. The system establishes a trusted digital archive for transformers throughout their entire lifecycle, from "birth" to "scrapping," supporting precise traceability down to the component and operation record levels. On the other hand, through a distributed storage architecture, the system effectively avoids single points of failure and centralized attack risks. Combined with encryption algorithms and access control, it further ensures data privacy and security. Furthermore, by utilizing smart contracts, the previously manually driven operation and maintenance process is transformed into an automatically driven execution process based on trusted data, significantly improving operation and maintenance efficiency, reducing human error, and achieving closed-loop management of predictive maintenance. Moreover, the system adopts a hybrid storage mode of "hash on-chain, raw data local storage," ensuring data credibility while avoiding the high cost of directly uploading massive amounts of raw data to the blockchain, thus possessing high engineering practical value.
