[0031] In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present invention. However, it should be clear to those skilled in the art that the present invention may be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from obstructing the description of the present invention.

[0032] In order to make the purpose, technical solutions and advantages of the present invention more clear, specific embodiments will be described below in conjunction with the accompanying drawings.

[0033] In order to improve the digital collaborative design methods of cable engineering, it is a future development trend to adopt more advanced 3D modeling technology to solve the survey data in cable engineering and liberate designers from repetitive work.

[0034] With the gradual rise of 3D Geographic Information System (GIS) technology, 3D modeling technology has the advantages of intuitive design results, high design efficiency, and convenient results management. At present, the field of power transmission and transformation engineering design has carried out exploration of 3D modeling and 3D digital design and achieved certain results. With the development and popularization of information technology such as 3D modeling and GIS, 3D modeling technology provides new technical means for parametric modeling of pipeline network data.

[0035] With the development of informatization, the connection between regions will inevitably become closer in the future. Underground cables are the lifeline to ensure stable power supply in the region, and the exchange of underground cable information between multiple regions is the basis for ensuring stable power supply. However, the modeling methods used by various regions for underground cables are diverse, and it is difficult to exchange underground cable information between regions. There is a hidden danger of unstable power supply due to untimely information exchange. Therefore, a correlation modeling method for underground cables in multiple regions is urgently needed to ensure the stable operation of the power grid.

[0036] See also Figure 1 , which shows a flowchart of the implementation of the multi-region underground cable association modeling method provided by the embodiment of the present invention. Figure 1 As shown, a correlation modeling method for underground cables in multiple regions may include:

[0037] S101, obtain target underground cable information in a target area, and upload the target underground cable information to a related blockchain; the target area is one of M areas, where M is a positive integer.

[0038] Optionally, the region to be associated can be divided into M regions based on cities, and each city can correspond to a node on the associated blockchain.

[0039] For the target area, the target underground cable information of the target area can be uploaded to the target node corresponding to the associated blockchain. The target underground cable information can include the pipe network parameters of the underground cable or the path map of the underground cable and other information used to build the model of the underground cable, such as type, attribute, path point information, and topological information of key inflection points.

[0040] S102, establishing an associated underground cable model of the target area according to the target identifier and target underground cable information of the target area; the target identifier is a unique identity identifier of the target area in the associated blockchain.

[0041] Optionally, in the associated blockchain, each node has a unique identity. Therefore, the target identity is the unique identity of the target area in the associated blockchain. Existing three-dimensional modeling methods can be used to establish a three-dimensional model of underground cables based on the target underground cable information in the target area, and the established three-dimensional model can be bound to the target identity to obtain the associated underground cable model of the target area in the associated blockchain. For example, three-dimensional GIS technology can be used for modeling.

[0042] Optionally, after establishing the associated underground cable model of the target area, the associated underground cable model can be stored in a server in the target area, and the storage identifier can be uploaded to the target node of the associated blockchain. When other areas on the associated blockchain want to obtain the associated underground cable model of the target area, they can obtain the associated underground cable model of the target area by accessing the storage identifier.

[0043] Optionally, to ensure data security, the storage identifier can also be encrypted, and only when the storage identifier is accessed through a node in the associated blockchain, the visitor will obtain the plaintext form of the storage identifier, otherwise the visitor or intruder can only obtain the ciphertext of the storage identifier. The present invention can determine whether the access is a normal access or an illegal access while ensuring data storage security, so as to prevent the leakage of the associated underground cable model in the target area.

[0044] Optionally, it is possible to detect whether the target underground cable information has changed every preset time. If the target underground cable information has changed, the associated underground cable model of the target area is updated. If the target underground cable information has not changed, a target detection identifier is generated, and the target detection identifier is bound to the associated underground cable model of the target area. The target detection identifier is used to represent the number of detections of the associated underground cable model of the target area, which is helpful for staff to query and improve the reliability of maintenance.

[0045] S103, establishing associated underground cable models for other regions in the associated blockchain in the same manner as establishing the associated underground cable model for the target region.

[0046] Optionally, in order to ensure the consistency of information exchange between underground cable models in M ​​regions, the same modeling method needs to be adopted to establish the associated underground cable models corresponding to the M regions. Accordingly, the storage identifier of the associated underground cable model of each region can be encrypted corresponding to the region, and only visitors who access through the associated blockchain can obtain the associated underground cable models of the M regions.

[0047] In addition, the associated underground cable models established in M ​​regions can also be stored in a fixed server, and the nodes of the associated blockchain only store the storage identifiers corresponding to the M regions. Visitors can obtain the associated underground cable model of the visited region by accessing the storage identifier.

[0048] The embodiment of the present invention uploads the underground cable information of M regions to the associated blockchain. Then, for each region, an underground cable model is constructed based on its unique identity in the associated blockchain and the underground cable information of the region. Finally, the M regions are associated through the associated blockchain. By adopting the modeling method of the present invention, the M regions are associated and modeled in the same way, which can improve the reliability of underground cable information exchange between multiple regions, ensure the normal power supply of the power grid, and improve the reliability of power consumption for users.

[0049] In some embodiments of the present invention, uploading target underground cable information to a related blockchain includes:

[0050] The target cable information is encapsulated into a modeling database, and the modeling database is uploaded to the associated blockchain.

[0051] Optionally, the target cable information can be stored in a modeling database to ensure data integrity, and then the modeling database can be uploaded to the associated blockchain. The target cable information can be stored in the modeling database for data detection at preset intervals to determine whether the target cable information is updated.

[0052] In some embodiments of the present invention, the target underground cable information includes underground cable paths and inflection point topology information; establishing an associated underground cable model of the target area according to the target identifier of the target area and the target underground cable information includes:

[0053] Perform three-dimensional modeling based on the cable path and inflection point topology information of the target area to obtain a three-dimensional model of the target area;

[0054] The target identifier is bound to the three-dimensional model of the target area to obtain the associated underground cable model of the target area.

[0055] Optionally, existing 3D modeling software may be used to perform 3D modeling based on the cable path and inflection point topology information of the target area, such as Google Earth, World Wind, GeoGlobe, or EV-Globe.

[0056] For M regions, the unique identity identifiers of the M regions in the associated blockchain can be bound to the established associated underground cable models, so that the associated underground cable models of the M regions are connected through the associated blockchain, thereby improving the reliability of information exchange between the M regions.

[0057] In some embodiments of the present invention, after establishing the associated underground cable models of other areas to be associated in the associated blockchain in the same manner as establishing the associated underground cable model of the target area, the method further includes:

[0058] After the associated underground cable model of the target area is updated, the updated associated underground cable model of the target area is broadcasted to other areas of the associated blockchain through the target identifier.

[0059] Optionally, after the associated underground cable models of M regions are established, when the associated underground cable model of the target region is updated, the update information can be broadcast to other regions of the associated blockchain; or, instead of broadcasting the update information to other regions of the associated blockchain, a new associated underground cable model is established based on the updated target underground cable information, and only the model is updated. Other regions can directly access the new model information when needed.

[0060] In some embodiments of the present invention, the method further comprises:

[0061] When a new region joins the associated blockchain, control the new region to send a network access application to the associated blockchain, and control the M regions in the associated blockchain to vote for network access; when the result of the network access vote is approval, control the new region to join the network;

[0062] In the same manner as the associated underground cable model of the target area is established, an associated underground cable model of the new area is established in the associated blockchain.

[0063] Optionally, when a new region needs to join the established associated blockchain (i.e., access the network), the new region can be controlled to send an access application to the associated blockchain, and the M regions in the associated blockchain can be controlled to vote for the new region through M nodes. Only when the number of votes in favor is greater than the preset number of votes, the result of consent to access the network is generated, the new region is allowed to access the network, and a unique identity is assigned to the new region. The new region establishes the associated underground cable model corresponding to the region based on the assigned unique identity and the underground cable information of the region.

[0064] By adopting the network access voting method and setting network access requirements for new regions, it is possible to improve the information security of regions in the associated blockchain and enhance the stability of grid operation.

[0065] In some embodiments of the present invention, before controlling the M regions in the associated blockchain to vote for network entry, the method further includes: empowering the M regions according to their regional areas.

[0066] Alternatively, a larger area indicates a larger underground cable scale in the area, which contributes more to the stable operation of the power grid. Therefore, each area can be weighted according to its area, that is, each area is given a different number of votes. The larger the area, the more votes it has, and the greater the weight it has when voting for the new area to join the network.

[0067] Beneficial effects of the present invention:

[0068] The present invention can associate the three-dimensional models of underground cables in multiple regions, improve the reliability of underground cable information exchange between regions, and contribute to the stable operation of the power grid. The present invention can also improve the security of accessing underground cable model information and reduce the possibility of underground cable information leakage. The present invention can also improve the compatibility between regions, allow new regions to access the network through voting, and enhance the connection between multiple regions under the premise of ensuring safety.
