[0049] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0050] This application provides a blockchain-based trusted traceability query method for power grid asset data, which is applied to power grid data management platforms, such as Figure 1 As shown, the power grid data management platform includes a blockchain platform 10, and an asset management system 20, an IT asset operation and maintenance management mobile application system 30 and a financial management system 40 connected to the blockchain platform 10.

[0051] In an exemplary embodiment, Figure 2-Figure 3 As shown in the figure, the trusted traceability query method for power grid asset data based on blockchain includes:

[0052] S201, the blockchain platform determines whether a warning situation occurs based on the hash value matching of the previous and next blocks.

[0053] The blockchain platform uses the unique data structure and security features of the blockchain to monitor the state changes of the blockchain. Each block of the blockchain contains the hash value of the previous block (i.e. a digital fingerprint). This design ensures the integrity and immutability of the blockchain. By comparing the hash value of the current block with the previous (or multiple) blocks, it can be determined whether a situation that requires early warning has occurred.

[0054] Optionally, in addition to simple hash value matching, you can also build a machine learning model to identify potential fraud, security risks, or business anomalies, thereby triggering early warnings more accurately.

[0055] S202, when the blockchain platform determines that a warning situation has occurred, it generates and stores warning information.

[0056] Once a warning situation is detected, the corresponding warning information is immediately generated. This warning information may include the time when the warning occurred, the blocks involved, transaction details, the type of anomaly, and the possible risk level. The warning information is then stored on the blockchain to ensure its immutability and traceability.

[0057] In addition to being stored on the blockchain, warning information can also be copied to other reliable data storage systems to improve data security and availability. In addition, warning information can be automatically classified for subsequent analysis and processing.

[0058] For example, the warning information can be classified according to the type of system involved, and divided into three categories according to asset management system 20, IT asset operation and maintenance management mobile application system 30 and financial management system 40. It can also be classified according to risk level, so that management personnel can sort and process according to different risk levels, and give priority to processing content with high risk levels.

[0059] S203, the blockchain platform generates a push message to the target user terminal according to the warning information and reminder rules.

[0060] After the warning information is generated, how to push the warning information to the relevant target users (the target user terminal refers to the terminal device held by the user who needs to receive the relevant warning reminder) according to the preset reminder rules (such as risk level, user role, user preference, etc.). The warning information is pushed in the form of push messages. The push messages may carry the query link of the warning information, but may not directly attach the entire content of the warning information. The push messages may be sent to users through email, SMS, mobile application notifications, etc.

[0061] In order to improve the user experience, multiple push channels can be supported, and users can be allowed to customize the way and frequency of receiving warnings. In addition, the push strategy can be optimized based on the user's historical behavior and feedback to ensure that the warning information can be conveyed to the target users in a timely and accurate manner.

[0062] S204, the target user terminal displays the push message, and in response to the triggering operation of the query link in the push message, jumps to the query tracing interface.

[0063] After receiving the push message on the target user terminal, the user can click the query link in the message to learn more about the warning details. After clicking the link, the target user terminal (such as a mobile phone, computer, etc.) will automatically jump to the query and traceability interface.

[0064] The query and traceability interface should be designed to be intuitive and easy to use, allowing users to quickly understand the context of the warning, the scope of impact, and possible solutions. In addition, the interface can also provide interactive functions, such as filtering conditions, so that users can conduct more in-depth analysis and queries according to their needs.

[0065] S205, the target user terminal responds to the user's query screening condition entry operation and confirmation operation performed on the query tracing interface, retrieves the warning information stored on the blockchain and displays it.

[0066] On the query traceability interface, users can enter query filter conditions (such as time range, block number, risk level, device name, etc.) and submit the query request by clicking the "OK" button. The terminal will retrieve relevant warning information from the blockchain based on these conditions and display it to the user.

[0067] In order to improve query efficiency, the target user terminal can support a variety of query optimization technologies, such as indexing, caching, etc. In addition, visualization tools such as charts, timelines, etc. can be provided to help users better understand and analyze warning information. Ultimately, users can use this information to formulate countermeasures or take other actions to reduce potential risks or losses.

[0068] Among them, in the screening conditions, the optional range of using departments and users is constrained based on the management authority of the user's login information. For example, if the user is the supervisor of Department A, he can only query the warning inconsistency events caused by employees of Department A in the asset data management process. On the one hand, it is conducive to the division of management responsibilities based on authority and avoids information confusion caused by cross-management. On the other hand, streamlining the content in the drop-down menu can help improve the efficiency of query tracing.

[0069] Specifically, the blockchain platform determines whether an early warning situation occurs based on the hash value matching of the previous and next blocks, and generates and stores early warning information when it is determined that an early warning situation occurs. Then, according to the early warning information and reminder rules, a push message is generated to the target user terminal, and the push message is displayed on the target user terminal side, so that the target user can receive the push message on the terminal side in the first time and understand the early warning situation. In response to the triggering operation of the query link in the push message, it jumps to the query tracing interface. The target user terminal responds to the query screening condition entry operation and the determination operation performed by the user on the query tracing interface, and retrieves and displays the early warning information stored on the blockchain. Through early warning judgment, in the event of an early warning, based on accurate push and query link generation, users can timely perform query tracing related to the early warning information on the target user terminal, avoiding users from searching for needles in a haystack in the database, and only focusing on the content related to the early warning information. In addition, the entire implementation process relies on the anti-tampering capability of the blockchain and reminder rules for push, which can take into account both data query efficiency and security.

[0070] In one embodiment, if Figure 4 As shown, in response to the triggering operation of the query link in the push message, jump to the query tracing interface (such as Figure 5 shown), including:

[0071] S401, in response to a triggering operation on a query link in the push message, obtaining user login information of a target user terminal.

[0072] Among them, when it is monitored that the user clicks or performs other triggering operations (dragging, etc.) on a specific query link in the received push message on his terminal device (such as a smart phone, computer, etc.). In response, the target user terminal needs to identify and execute this request. First, it needs to obtain the user login information of the current user on the user terminal. The user login information may include the user name, department, unit, position, etc., which is used to verify the user's identity and authority in subsequent steps. Users in different departments and positions have different corresponding query permissions.

[0073] Push messages can include clear and concise instructions, such as important information such as risk level, so that users can decide whether to click the query link as soon as possible based on the risk level.

[0074] After sending a push message to the target user terminal, the target user terminal can display the push message compatibly according to the terminal type (such as iOS, Android, Web, etc.) to ensure that the push message can be received and viewed normally on each type of target user terminal.

[0075] Depending on the application, the login information may be obtained through Cookies, SessionStorage, LocalStorage, etc. stored on the local device, or through the user re-login process.

[0076] S402, verifying whether the user login information has query authority.

[0077] After obtaining the user's login information, verify whether the information is valid and check whether the user has the authority to access or perform operations associated with the query link in the push message to ensure that only authorized users can access the warning information or perform warning information viewing operations.

[0078] Among them, permission verification can be based on multiple factors, such as the user's role (such as administrator, ordinary user), the organization or department to which the user belongs, etc.

[0079] Optionally, if the verified user does not have query permissions, clear feedback should be provided to inform the user of the reason and possibly guide the user to apply for permissions or log in again.

[0080] S403: If the authority verification is passed, jump to the query tracing interface.

[0081] If the user's login information passes the permission verification, the operation requested by the user will be performed, that is, jumping to the query and traceability interface. This interface allows the user to view or trace the detailed information of the data or operation associated with the push message.

[0082] The interface can also support users to perform further operations, such as exporting data.

[0083] After the user completes viewing or operating on the query traceability interface, the query traceability interface may also provide an exit or return button. The user clicks the exit or return button to return to the query traceability interface home page (such as Figure 5 The interface diagram shown in the figure shows the user login name in the upper right corner, the upper area shows the filtering conditions, and the lower area shows the warning information queried under the filtering conditions).

[0084] In one of the embodiments, the warning information includes device name, device code, operating status, risk level, inconsistent field, blockchain field value, asset management system field value, IT asset operation and maintenance management mobile application field value, financial management system field value and marking operation; the push message includes a query link and risk level.

[0085] The query link and risk level can be displayed in the push information to improve the simplicity of the push message and facilitate users to perform subsequent query operations based on the risk level. For example, when the risk level is low, the user does not need to handle it immediately, but when the risk level is high, the user needs to click on the query link immediately to understand the specific warning information and make corresponding operations such as deleting abnormal blocks.

[0086] In one embodiment, the target user terminal responds to the user's query screening condition entry operation and confirmation operation performed on the query tracing interface, and before the step of retrieving and displaying the warning information stored on the blockchain, further includes:

[0087] Obtaining user login information of a target user terminal, and determining, based on the user login information, a query screening condition that matches the authority of the user login information;

[0088] The matching query screening conditions are displayed on the query tracing interface.

[0089] First, the user login information is obtained and the permissions are determined accordingly. This can accurately control the access rights of different users to the warning information, effectively prevent unauthorized access to the warning information, and enhance data security and privacy protection. In addition, by obtaining the user login information, the query and filtering conditions that match their permissions are displayed to the user, avoiding the user from attempting invalid operations without access rights, thereby saving user time and improving query efficiency. In addition, by controlling the query and filtering conditions through permissions, it is helpful to uniformly manage and standardize data access within the power grid, ensuring that the circulation of power grid asset data-related content complies with established security policies and business processes.

[0090] Optionally, the above method also includes: recording all operations performed by users in the query traceability interface, including login, query filter condition setting, query result viewing, etc., so that administrators can monitor user behavior and promptly discover potential security risks or violations.

[0091] In one embodiment, the warning information is displayed in a list form, and the method further includes:

[0092] In response to a click operation on one of the warning information in the list, the target user terminal displays a traceability details interface (such as Figure 6 As shown), the traceability details interface displays the latest data on the chain and the historical data of the entire life cycle of the power grid asset data corresponding to the early warning information.

[0093] Among them, Figure 5 The middle area of ​​the display shows the warning information in a list format, which allows users to quickly browse and identify a large amount of warning information. The list usually includes the key elements of each warning information, such as time, asset number, risk level, etc. Users can quickly locate the warning inconsistency information of interest based on the information displayed in the list, which is conducive to further improving the efficiency of viewing and tracing.

[0094] Based on the setting of early warning rules, inconsistent data records throughout the entire life cycle can be realized, so the query of inconsistent data throughout the entire life cycle is supported.

[0095] You can find monthly statistics of inconsistent data on the homepage of the blockchain data governance platform, such as Figure 7 As shown, the figure has been anonymized for the purpose of illustration. The statistical results can be presented in the form of bar charts and lists.

[0096] Through the statistical information, you can select the asset system inconsistency rate, financial system inconsistency rate, and asset application system inconsistency rate drop-down menu. You can then reach the inconsistent information query interface for that month. You can also directly click on the data inconsistency query in the left navigation bar to navigate to the data inconsistency query interface (such as Figure 8 as shown).

[0097] The data inconsistency query interface can be filtered according to inconsistent systems (including the above asset system, financial system and IT asset operation and maintenance management mobile application system), verification date, risk level, customer number, equipment name, processor, processing status, unit, etc. After filtering, you can click the details operation to view the details of the IT asset data (such as Fig. 9 Abnormal information is shown in red).

[0098] In the details interface, you can view the latest data content of IT asset data, and you can also view inconsistent data in the inconsistent information column.

[0099] Inconsistent data can be exported through the export function of the data verification summary interface. The exported data structure can be as follows:

[0100]

[0101] The blockchain-based trusted traceability query method for power grid asset data provided in the embodiment of the present application designs front-end functions on the basis of supporting full life cycle data governance in the background, and realizes trusted traceability of full life cycle data based on blockchain trusted traceability. The interface design can support fast query of data, and cooperate with authority management to intelligently push warning inconsistent information, as well as streamlined optimization of the drop-down options of the query interface screening conditions. Different optional data ranges are provided for query according to different positions and roles, and personalized query interface display based on roles is supported, thereby further improving data management security and query efficiency.
