Description

Technical Field

[0002] GIM, short for Grid Information Model, is a term used in the power industry. It refers to a technical standard developed by State Grid Corporation of China to meet the needs of three-dimensional design for power transmission and transformation projects. It is a scalable State Grid GIM standard system developed independently by the State Grid Economic Research Institute through the establishment of a unified data architecture, coding system, interaction method, design depth, and output format, suitable for power transmission and transformation project construction.

[0003] In the existing technology, although models such as electrical equipment in the GIM model system have corresponding attribute information and engineering structure hierarchy information, and can support online viewing of model information; however, only static model setting attribute information can be seen. After the physical object is used, the early attribute information of the physical object cannot be displayed. At this time, construction personnel need to go to the site to obtain the physical attribute information, causing construction troubles; in addition, if there is a lack of feedback on physical information during engineering construction, it may lead to safety, quality and other problems due to the lack of physical information.

[0004] Physical "ID" is the unified identification code for physical assets in the power grid, serving as the "identity card" issued to power grid equipment.

[0059] Various exemplary embodiments, features, and aspects of the present disclosure will be described in detail below with reference to the accompanying drawings. The same reference numerals in the accompanying drawings represent elements with the same or similar functions. Although various aspects of the embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless otherwise indicated.

[0060] The word “exemplary” is used exclusively herein to mean “serving as an example, example, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.

[0061] In addition, numerous specific details are provided in the following detailed description to better illustrate the present disclosure. Those skilled in the art will appreciate that the present disclosure can be practiced without certain specific details. In some instances, methods, means, components, and circuits well known to those skilled in the art are not described in detail in order to highlight the main points of the present disclosure.

[0062] Example 1

[0063] According to one aspect of the present disclosure, Figure 1 As shown, an application method for extending physical ID based on the GIM model is provided, which includes the following steps:

[0064] S1. Analyze the GIM model and its storage structure to obtain the GIM model and its attribute information;

[0065] This application requires first parsing the GIM model and sorting out the GIM model framework to obtain the electrical equipment model and attribute information, as well as the engineering hierarchical relationship structure of the model file;

[0066] The GIM model framework includes four parts: attribute set FAM, component class PHM, physical model DEV / logical model SCH, and engineering model CBM;

[0067] In the GIM model system, standard format files are stored according to four directory structures. The data stored in standard format files include: geometric model units (*.mod), combination models (*.phm), physical models (*.dev), logical models (*.sch), engineering models (*.cbm) and attribute information (*.fam).

[0068] By parsing the GIM model and its storage structure, analyzing the electrical equipment model and attribute information, the engineering hierarchical relationship structure is obtained. In order to facilitate the subsequent matching and search for the model corresponding to the physical ID, the association relationship between the physical ID and the GIM equipment model is established in advance.

[0069] S2. Establishing an association relationship between the physical object ID and the GIM device model based on the GIM model and its attribute information;

[0070] The object ID information is set by the user, and attribute information bytes are added at the corresponding address position. The information of the object is edited by the user according to the specific attributes of the device. The association relationship is established in advance based on the correspondence between the object and the GIM model system to facilitate the subsequent matching of model files.

[0071] After establishing the association between the physical ID and the GIM equipment model, and subsequently loading the model file, the physical equipment attribute information can be visualized on the GIM system platform, supporting full-scene applications in traditional engineering construction stages such as construction site progress, safety, quality, cost, technology, and materials; engineering equipment models, physical ID codes, and various attributes can also be viewed online in real time, realizing the information flow of equipment attributes containing physical IDs at various stages of construction.

[0072] The physical object ID information and the corresponding relationship between the GIM model and the physical object can be selectively set by the user based on the specific usage scenario and device properties, and there is no restriction here.

[0073] S3. Traverse the GIM system engineering hierarchical relationship structure to obtain the target node address information.

[0074] like Figure 2 The figure shows the engineering hierarchical relationship structure of the GIM system. In this embodiment, it includes four levels of engineering hierarchical relationships, specifically:

[0075] a. A first-level project (file extension cbm, system-level description ENTITYNAME = F1System) contains several second-level projects;

[0076] b. A secondary project (file extension cbm, system-level description ENTITYNAME = F2System) contains several tertiary projects;

[0077] c. Level 3 project (file suffix cbm, system level description word ENTITYNAME = F3System), including several level 4 equipment systems;

[0078] d. Level 4 device system (file suffix cbm, system level description word ENTITYNAME = F4System, system device level).

[0079] In this embodiment, taking the addition of physical ID information to level 4 equipment (facility) as an example, it is necessary to perform an address query on the level 4 equipment (facility). First, the engineering hierarchy relationship is traversed, and the engineering hierarchy relationship structure is traversed through a multi-branch tree traversal method. The depth-first method is implemented recursively to finally obtain the desired target node address information. The specific traversal and address acquisition are described in detail below.

[0080] S4. Add physical object ID information according to the target node address information.

[0081] After obtaining the target node address information, add a field at this address location and add the physical ID.

[0082] After adding the physical object ID information in the GIM model system, you can view the physical object attribute information through the system after loading the model file later.

[0083] like Figure 2 As shown, the model file is loaded from the file entry, and the four-level engineering hierarchy is experienced. The multi-tree traversal method is used to traverse from the first-level full station to the fourth-level equipment (facility). Through the multi-tree traversal and deep optimization traversal method, the corresponding ".fam" model address is finally found. According to this address, the physical ID is written through the field. Figure 4 As shown, the object ID information can be finally seen in the node text of the model file, so that the object attribute information can be checked on the GIM model platform.

[0084] It should be noted that while the above-level traversal and address acquisition are described using Level 4 devices (facility) as an example, those skilled in the art will appreciate that this disclosure is not limited to this. In fact, users can flexibly configure this based on their personal preferences and / or actual application scenarios by simply adding physical object ID information to the GIM model.

[0085] In this way, by parsing the GIM model and its storage structure, the GIM model and its attribute information are obtained; based on the GIM model and its attribute information, an association relationship between the physical ID and the GIM equipment model is established; the GIM system engineering hierarchical relationship structure is traversed to obtain the target node address information; based on the target node address information, the physical ID information is added; by extending the physical ID information in the GIM model and attaching a physical ID code to the GIM model, the three-dimensional design model and the "physical ID" are associated with each other, laying a data foundation for the use of three-dimensional design results in the construction and operation and maintenance stages.

[0086] Through this application, during the power grid construction phase, rapid information management based on physical IDs such as material arrival and construction progress can be achieved, and construction simulation can be carried out; during the operation and maintenance phase, operation and maintenance emergency drills, operation and maintenance data visualization monitoring, etc. can be achieved.

[0087] The present invention is based on an innovative way of associating physical IDs with three-dimensional models. In addition to supporting full-scenario applications in traditional engineering construction stages such as construction site progress, safety, quality, cost, technology, and materials, it can also view engineering equipment models, physical ID codes, and various attributes in real time online, thereby realizing the information flow of equipment attributes containing physical IDs at all stages of construction.

[0088] As a model file attribute loading method of this system, in one possible implementation,

[0089] Also includes:

[0090] Load the GIM model file;

[0091] Input the GIM model file into the system through the tool software and use the tool to load it into the GIM model system;

[0092] Decompress the GIM model file and obtain the file header information.

[0093] In this embodiment, the 7z third-party tool is used to decompress the gim format file according to the 7z format and obtain the header information of the gim file;

[0094] The GIM model file type is determined according to the file header information.

[0095] Based on the file header information, we can know the type of the loaded GIM model file and judge it as a substation or transmission type, which makes it easier to traverse and match the corresponding model in the engineering hierarchical relationship structure.

[0096] The 7z third-party tool is only a pressurizing tool in this embodiment. The specific implementation is not limited to the 7z third-party tool and can be selected by the user.

[0097] In one possible implementation,

[0098] Also includes:

[0099] Based on the GIM model file type, traverse all system and device files according to the GIM specification;

[0100] After obtaining the type of the loaded GIM model file, all system and device files are traversed according to the GIM specification, that is, the files in the engineering hierarchy relationship structure are traversed according to the file type to obtain the engineering hierarchy relationship structure related to the GIM model file type.

[0101] When writing physical ID information, this technology uses a multi-tree traversal method to traverse the engineering hierarchical relationship structure and implements depth-first in a recursive manner.

[0102] In one possible implementation,

[0103] The acquisition of target node address information includes:

[0104] Based on a multi-tree traversal method, the engineering hierarchical relationship structure is traversed and initial node data is output.

[0105] like Figure 3 As shown, the first element of each row of the multitree specifies a node, where the first row specifies the root node of the multitree; the second element indicates how many child nodes the node has, followed by several child nodes.

[0106] Based on a level-first traversal method, the initial node data is output according to the depth to obtain the first node data;

[0107] Through the level-first traversal method, the nodes are output according to the depth, combined with Figure 3 For example, first output the deepest node: xej, then output the node with a depth of 2: dfi, then output the nodes with a depth of 1: g cC z bBbB, and finally output the root node: aA.

[0108] The implementation principle of level-first traversal is to start from the root node and use the level-first traversal method to solve it. The queue can be used to implement the output of the deep node, that is, to obtain the first node data.

[0109] Based on the depth-first traversal method, the node with the longest path from the root node to the leaf node on the multi-branch tree is obtained from the first node data as the target node.

[0110] In this embodiment, a depth-first traversal method is used to obtain the target node address information, wherein the determined address information of the target node is located in the first node data, and the depth-first traversal method is used here to find the target node.

[0111] exist Figure 3 In the multi-branch tree shown, the calculated paths between nodes vary in length. A depth-first traversal method is used to solve all paths from the root node to the leaf nodes. The path with the longest sum of the node names on all paths is obtained, that is, aA bBbB. This is used to find the target node and use it as the address location for adding the physical ID information.

[0112] After finding it, add the physical ID attribute information in the fourth-level equipment (facility) directory. Figure 4 As shown, in a node text information display diagram, you can see that the physical ID has been added after the physicalid directory node position of the text directory.

[0113] like Figure 4The figure below shows a diagram of the visual display page after adding the physical ID information. After the information is entered, the engineering equipment model, physical ID code and various attributes can be viewed online in real time on the system, realizing the information flow of equipment attributes containing physical ID at various stages of construction.

[0114] Example 2

The functions and information transmission of each module in the system are the same as the implementation method and principles described in Example 1. See Example 1 for details.

[0119] The system traversal module is used to traverse the GIM system engineering hierarchical relationship structure and obtain the target node address information;

[0120] The information adding module is used to add physical object ID information according to the target node address information.

[0121] After the parsing module parses the GIM model and its storage structure and obtains the GIM model and its attribute information, the parsed data is sent to the association relationship establishment module, which establishes an association relationship between the physical object ID and the GIM device model based on the GIM model and its attribute information;

[0122] After the physical model file is loaded through the GIM model system, the GIM system engineering hierarchical relationship structure is traversed through the system traversal module to obtain the target node address information of the physical model corresponding to the system, and the loaded physical model is matched with the model of the GIM model system to find the corresponding position, and then the physical ID information is added through the information adding module.
