The connection among the data, the documents and the models of each stage of the power transformation project is currently dependent on manual formalization management, the organization degree among various data is low, and each stage of data island is easy to form, so that more time consumption exists in the next stage of resource lifting and resource collection. In the conventional technology, the substation engineering data is managed by utilizing COBie (Construction Operations Building information exchange, construction operation data exchange standard) so as to realize data circulation. However, there are still some difficulties in using COBie in power transformation engineering, and first, when COBie is used, since the COBie workbook consists of 20 worksheets, it is difficult for users to find relevant data and understand the dependency relationship between information due to the excessive tables. Second, each worksheet defines a particular type of information, and the structure of the worksheet is fixed, resulting in a large number of empty values in each worksheet in actual use. Finally, since the data needs to be transferred between different stages, which depends on manual filling, manual input is time-consuming and is prone to data errors or omissions. In addition, the use of COBie can lead to problems of difficult data transfer, interaction and lack of visual flow in the whole life cycle of the transformation project.

The portable wearable device may be a smart watch, smart bracelet, headset, or the like. The server 104 may be implemented as a stand-alone server or as a server cluster of multiple servers.

In one embodiment, as shown in fig. 2, a power transformation project data management method is provided, and the method is applied to the terminal in fig. 1 for illustration, and includes the following steps:

step 202, in each engineering stage of the transformer engineering, acquiring stage data of an engineering object in the engineering stage and circulation data of a previous engineering stage, and storing the stage data of the engineering stage and the circulation data of the previous engineering stage into a data model diagram of the engineering stage; the data model graph is constructed in accordance with the format of the graph database.

The whole life cycle of the power transformation project comprises a plurality of project stages, such as planning, designing, constructing, operating and maintaining and the like. The engineering stages are provided with a fixed time sequence, and each engineering stage is completed sequentially according to the time sequence. The project object refers to a project body related to the power transformation project, including electrical equipment and civil facilities. The phase data of the engineering phase refers to the data required to complete the engineering phase. The streaming data refers to data shared in different engineering stages. The data model diagram refers to a storage structure for storing phase data and circulation data, and each engineering phase corresponds to one data model diagram. The format of the graph database is a topology.

Specifically, for each engineering stage of the power transformation engineering, stage data of the engineering stage and circulation data of the previous engineering stage may be acquired. The phase data may include geometric data, attribute data, and engineering data. The circulation data of the previous engineering stage is obtained by updating the shared data of the previous engineering stage after the previous engineering stage is completed. And storing the stage data of the engineering stage and the circulation data of the previous engineering stage into a data model diagram of the engineering stage. The data model diagram of the engineering stage is constructed according to the topological structure in advance, and the data model diagram of the engineering stage comprises a plurality of nodes formed by stage data of the engineering stage and circulation data of the previous engineering stage and edges among the nodes. Edges between nodes represent hierarchical relationships, i.e., dependencies, between nodes. The dependency relationship between the data can be clearly understood through the data organization form of the nodes and the edges in the data model diagram.

Thereafter, the engineering stage may be completed based on the data in the data model diagram. It is understood that the processing manner of the transformation project at each project stage may be a processing manner known to those skilled in the art.

And 204, extracting the shared data of the engineering stage from the data model diagram, and updating the shared data to obtain the circulation data of the engineering stage.

Wherein, the data model diagram stores shared data and independent data. Shared data refers to data that needs to be circulated in different engineering stages. Independent data refers to phase data that is only saved in the current engineering phase.

The definition of the shared data is preset in the data model diagram, and after the stage data of the engineering stage and the circulation data of the previous engineering stage are stored in the data model diagram of the engineering stage, the shared data of the engineering stage can be directly extracted from the data model diagram after the engineering stage is completed. The shared data is updated, and the updating process can comprise redundant data removal, data supplementation and refinement, so that the circulation data of the engineering stage is obtained. Alternatively, the course of the update process may be determined based on actual phase requirements of the next engineering phase.

And step 206, transferring the circulation data flow of the engineering stage to the next engineering stage, updating the next engineering stage to the engineering stage, returning the stage data of the engineering stage and the circulation data of the previous engineering stage, and storing the stage data and the circulation data of the previous engineering stage in the data model diagram of the engineering stage until the stage data storage of the ending engineering stage of the power transformation engineering is completed.

The ending engineering stage refers to the last engineering stage of the power transformation engineering.

And transferring the circulation data stream of the engineering stage to the next engineering stage, for the next engineering stage, taking the circulation data of the engineering stage as the circulation data of the previous engineering stage, acquiring the stage data of the next engineering stage, taking the stage data of the next engineering stage as the engineering stage, returning the stage data of the engineering stage and the circulation data of the previous engineering stage to store the stage data of the engineering stage and the circulation data of the previous engineering stage into a data model diagram of the engineering stage, and repeating the steps of carrying out data management on the engineering stage to obtain the circulation data until the stage data of a final engineering stage of the power transformation project is stored into the data model diagram of the final engineering stage.

According to the power transformation project data management method, the data model diagram of each project stage is introduced, and the data model diagram is constructed according to the format of the diagram database, so that the stage data of each project stage and the circulation data of the previous project stage are stored in the data model diagram of the project stage, and the dependency relationship among the stage data, the circulation data and the circulation data in each project stage can be clearly expressed through the data organization form of the nodes and the edges in the data model diagram, so that the data visualization is realized. The definition of the shared data is preset in the data model diagram, the accurate and complete shared data can be obtained, the circulation data is obtained after automatic updating processing, and the circulation is carried out to the next engineering stage until the stage data storage of the ending engineering stage of the power transformation project is completed. The whole data management process does not need manual participation, so that the problem of data errors or omission in the manual data management process is avoided, and the problems that the data of the power transformation project in the whole life cycle are difficult to circulate, interact and lack visual flow in the traditional mode are solved. Meanwhile, the method does not depend on information exchange of a fixed structure, so that when null values appear in the data model diagram, null value rejection can be realized by deleting the relationship between null value nodes and upper nodes.

In one embodiment, the method further comprises: and in the first engineering stage of the power transformation engineering, acquiring stage data of the first engineering stage, and storing the stage data of the first engineering stage into a data model diagram of the first engineering stage.

And in the first engineering stage of the power transformation engineering, the previous engineering stage does not exist, only the stage data of the engineering stage is required to be acquired, the data model diagram of the first engineering stage is called, and the stage data is stored in the data model diagram of the first engineering stage.

In the embodiment, the first engineering stage of the power transformation engineering is stored in the data model diagram of the first engineering stage, so that the dependency relationship between stage data in the first engineering stage can be clearly expressed, and the visualization of the data is realized.

In order to prevent the data model graph from becoming larger like a snowball in the circulation process, a large amount of redundant data exists in the subsequent stage, and the data model graph of each engineering stage is divided into a core model graph and a scene model graph. The core model diagram refers to a storage structure of geometric data and attribute data of engineering objects at each stage in the whole life cycle of the power transformation project, and the scene model diagram refers to a storage structure of engineering data at each engineering stage in the implementation process of the power transformation project. In one embodiment, as shown in fig. 3, storing the phase data of the engineering phase and the circulation data of the previous engineering phase into the data model diagram of the engineering phase includes:

And 302, constructing a building information model of the engineering stage according to the geometric data and the attribute data of the engineering stage, and storing the building information model of the engineering stage into a core model diagram of the engineering stage.

And 304, constructing the association relation between the engineering data and the building information model of the engineering stage in the scene model diagram of the engineering stage.

For each engineering stage of the power transformation project, the stage data includes geometric data, attribute data, and engineering data. The geometric data refer to geometric model files of engineering objects (including electrical equipment and civil engineering facilities), such as transformers, reactors and the like in the electrical equipment and main control communication buildings, patrol centers and the like in the civil engineering facilities. The attribute data refers to attribute data corresponding to the geometric data. The engineering data may include working conditions, form parameters, defect information, etc. of the engineering object. The building information model refers to the BIM (Building Information Model) model.

Specifically, the transformer engineering manages geometric data and attribute data through a building information model, and the building information model of the engineering stage can be constructed according to the geometric data and the attribute data of the engineering stage. The core model diagram comprises a hierarchical structure sequence, and the data stored in the building information model of the engineering stage are sequentially stored into the core model diagram according to the hierarchical structure sequence of the core model diagram of the engineering stage. And storing the engineering data of the engineering stage into a scene model diagram.

Because the project data of each project stage in the life cycle of the power transformation project is stored in the scene model diagram. Compared with the continuous geometric data, the engineering data has more varieties and large differences of each engineering stage, so that the engineering data of each engineering stage in the scene model diagram is independently managed, and the application of the full life cycle is difficult to realize. In order to realize the circulation and application of engineering data in different engineering stages, the association relationship between engineering data and a building information model can be constructed while the engineering data is stored, so that the engineering data can be efficiently stored, retrieved and analyzed in the life cycle of a data model diagram.

For example, a logical structure diagram of a data model graph may be shown in fig. 4, where a scene model represents the scene model graph, a core model represents the core model graph, and a data model represents the data model graph. The full life cycle of the power transformation project can comprise a design stage, a construction stage and an operation and maintenance stage, and the corresponding data model of the full life cycle comprises a design stage data model, a construction stage data model and an operation and maintenance stage data model. LOD100, LOD300, and LOD500 represent model depths of a data model.

In the transformation engineering circulation, a BIM model in an IFC (Industry Foundation Classes, 3D model of a building) format is taken as a basic data model, only details of LOD100 are provided from the initial design, and information is continuously expanded and supplemented, the details of LOD300 are provided after the completion and change of the construction stage, the details of LOD500 are provided for the data model after completion, and a large amount of engineering data are also contained. The data model of each engineering stage can be divided into a circulation part and an independent part, wherein a dotted line cylinder represents the circulation part, a straight line cylinder represents the independent part, the data stored in the independent part is only stored in the data model of the current engineering stage, and the data stored in the circulation part can enter the next engineering stage after being updated. Both the stream portion and the independent portion may store engineering data via corresponding IFC formatted files. The core model only comprises a circulation part, the stored data are all data which need circulation, and the core model can store geometric data and attribute data through corresponding files in an IFC format. The scene model in the design stage is used for storing basic information data, design change data and construction drawing result data. The core model of the design phase is used to store design attribute data and detail data for the LOD 100. The construction phase scene model is used to store project execution data, completion error data, and completion handoff data. The core model of the construction phase is used to store construction attribute data and detail data of LOD 300. The scene model of the operation and maintenance stage is used for storing operation data, fault maintenance data and acceptance correction data. The kernel model of the operational phase is used to store the operational attribute data and detail data of the LOD 500.

In this embodiment, the combination of the BIM model and the core model diagram realizes the circulation of the geometric data and the attribute data, and the circulation data is the data subjected to the redundant data removal processing, so that the problem that the details and semantic information of the BIM model can be exponentially increased along with the continuous deepening of engineering, thereby increasing the difficulty of engineering management can be solved. The association relation between the engineering data and the building information model of the engineering stage is constructed in the scene model diagram of the engineering stage, the dependency relation between the engineering data and the geometric data in the building information model can be clearly shown based on a non-tabular storage form, and BIM data can be rapidly searched. When the data model flows, the engineering data is bound with the BIM model, so that only the relation is changed, and the new filling is not needed, so that the manual workload is reduced, and meanwhile, the error is avoided.

BIM models of different design software have different file format standards, and IFC files are used as main bearing of geometric data of the power transformation project, so that in order to realize circulation of a data model diagram, the IFC files are required to be connected with each engineering stage of the power transformation project. In one embodiment, constructing a building information model of the engineering stage according to the geometric data and attribute data of the engineering stage, and storing the building information model of the engineering stage in a core model diagram of the engineering stage in a form of a diagram database, including: building an IFC (IFC) format building information model of the engineering stage according to the geometric data and the attribute data of the electrical equipment and the civil engineering facilities in the engineering stage; and sequentially adding the data stored in the construction information model of the IFC format of the engineering stage into the core model diagram of the engineering stage according to the hierarchical structure sequence of the core model diagram of the engineering stage.

The engineering objects include electrical equipment and civil facilities. And constructing an IFC (IFC) type building information model of the engineering stage according to the geometric data and the attribute data of the electrical equipment and the civil engineering facilities in the engineering stage. And sequentially extracting data from the building information model in the IFC format as corresponding nodes according to the hierarchical structure sequence of the core model diagram of the engineering stage. Adjacent hierarchical nodes can be connected through edges to represent the association relationship between the nodes.

Optionally, when the constructed building information model is in a different file format, the building information model in the different file format may be converted into the IFC format, specifically, each component and member may be stored in the core model diagram according to a hierarchical form of the constructed IFC file by using each electrical device and unit building, and geometric information of the component and the component is organized according to the IFC class, and for this reason, the core model diagram also adopts a tree structure.

Further, the core model graph may be constructed according to a graph database Neo 4J. The core model map may be referred to below simply as a core model. Because of the huge number of electrical equipment, civil engineering facilities, components and members of the power transformation project, a graph database can be built in a layered mode, and then a core model can be built according to the graph database. First, a "core model" node is added to a graph database using the cytoer (graph database query language) syntax, and is used as a primary node. And secondly, adding 'electric equipment' and 'civil engineering part' nodes, and taking the nodes as secondary nodes, wherein the civil engineering part is civil engineering facilities. Then, all the electric devices and building names are imported and taken as three-level nodes, and the component and building member information of the corresponding devices is added as a fourth-level node. Finally, IFC class information, i.e. geometric and attribute data of the components, of each assembly of the building and the equipment is added as a fifth level node, such as ^{Watch (watch)} ₁ 。

Table 1 diagram database node definition

The core model is constructed according to the sequence from top to bottom in the graph database, node information is imported layer by layer from the first level to the fifth level, the structural diagram of the core model is shown in fig. 5, three-level nodes represent all electrical equipment and building names, and four-level nodes represent the equipment components and building member information. The power transformation project includes a large number of electrical devices, so the number of nodes is already very large at the fourth layer of the graph database. The fifth level node adopts the IFC class as a node unit of geometric and attribute data.

The graph structure data storage form of the core model can be shown in fig. 6, wherein each circle represents a node, edges between nodes represent a hierarchical relationship and an association relationship between nodes, and arrow directions of the edges are from a node with a low hierarchy to a node with a high hierarchy. "parallel power …" represents "parallel voltage". An edge of the "electrical equipment" node pointing to the "core model" node is "part_of" indicating that the "electrical equipment" is part of the "core model", and an edge of the "integrated building" node pointing to the "civil part" node is "include_in" indicating that the "civil part" includes "integrated building". The edge of the node of the 35 kv-parallel voltage, which points to the node of the parallel voltage, is 'belong_to', which means that the 35 kv-parallel voltage belongs to the parallel voltage. The graph comprises four-level nodes, and five-level nodes are IFC type information and are not shown.

Further, during circulation, granularity of the BIM model in the core model can be gradually increased along with the advancement of the power transformation project, so that details of the model need to be updated along with progress. In the design stage, the model only needs to represent the geometric data of the core components of the electrical equipment, such as the position and the size of the transformer bushing, the direction and the angle of the wiring terminal board are generally accurate, the projection size of the main body part on the ground is generally accurate, and the size and the positioning of the conservator are generally accurate. By the construction stage, the model needs to embody important nodes in the installation process, such as connected flange parts and civil engineering interfaces. In the operation and maintenance stage, the BIM model needs to be thinned to a ladder, a meter and the like to assist operation and maintenance personnel in checking the working condition of equipment, and granularity of each stage of the transformer BIM model is shown in a table 2.

Table 2 model granularity for each stage of transformer

In this embodiment, the construction information model of the IFC format of the engineering stage is constructed according to the geometric data and the attribute data of the electrical equipment and the civil engineering facility in the engineering stage. Since the format standard of the IFC file provides a hierarchical and semantic object-oriented organization for the BIM model to facilitate storage and exchange. Based on the method, engineering project participants with different professional backgrounds can effectively use BIM data and fully exchange information in electrical equipment, civil engineering or construction management, so that the high efficiency of data transfer is improved.

The circulating part and the independent part of engineering data need to be associated with the core model along with the progress of the stage of the life cycle of the power transformation engineering. At present, because the engineering data and the BIM model are disjointed, the BIM model can only assist the implementation of engineering, and therefore, the application adopts a graph database to construct the connection between the engineering data and the BIM model. In one embodiment, a core model graph includes a plurality of model component nodes, each model component node for storing model components in a building information model; the scene model diagram comprises a plurality of engineering data nodes, wherein each engineering data node is used for storing engineering data; constructing an association relationship between engineering data and a building information model of the engineering stage in a scene model diagram of the engineering stage, wherein the association relationship comprises the following steps: determining the corresponding relation between each model component node and engineering data node in the core model diagram in the scene model diagram of the engineering stage; and adding the engineering data of the engineering stage to the corresponding engineering data nodes according to the corresponding relation, and generating edges connecting the model component nodes and the associated engineering data nodes.

Wherein the model component refers to components of electrical equipment and building elements in the core model.

Compared with the civil engineering part, the engineering data of the electric equipment are relatively complex, and comprise the working conditions (rated voltage, rated capacity, rated current, rated frequency and the like) of the equipment, the appearance parameters (equipment name, equipment model, installation size identification system code, transportation size object ID code, upper-level equipment association number and the like) and the defect information (rated loss, winding oil temperature and the like). The spreadsheet representation, using COBie alone, therefore lacks a "model-attribute" joint storage approach, making it difficult for operators to understand the process of data flow and model evolution. And determining the corresponding relation between each model component node and the engineering data node in the core model diagram in the scene model diagram of the engineering stage, so as to establish the association between the model component node and the engineering data node.

Firstly, a form file in a CSV format is established according to engineering data associated with electrical equipment. And determining engineering data types corresponding to the engineering data, wherein the engineering data types refer to components of the electrical equipment, namely corresponding model components. Therefore, the corresponding model component node and the engineering data node can be determined according to the engineering data category, and meanwhile, the corresponding attribute information is added for the engineering data node, and the attribute information can comprise the attribute value corresponding to the engineering data.

Likewise, the type of engineering data corresponding to the engineering data of the building is determined, and the type of engineering data refers to the components of the building. Corresponding model component nodes, namely building element nodes and engineering data nodes, can be determined according to the engineering data of the building.

And adding the engineering data of the engineering stage to the corresponding engineering data nodes according to the corresponding relation, and generating edges connecting the model component nodes and the associated engineering data nodes, so as to construct and obtain the association relation between the engineering data and the building information model.

The graph structure data storage form of the scene model graph may be as shown in fig. 7, wherein the dashed circle represents engineering data, and the side of the "rated capacity" node pointing to the "conservator" node is "const_of" representing that the engineering data composition of the "conservator" includes "rated capacity".

In this embodiment, the components of each BIM model and their engineering data are made to correspond one-to-one by building flexible relationships. Based on a non-tabular storage form, the dependency relationship between the data is clearly acquired in the form of data organization of edges and nodes, and BIM data is quickly retrieved. Meanwhile, when null values appear in the data model without depending on data exchange of a fixed structure, the null values can be removed by deleting the relation between null value nodes and upper nodes. When the data model flows, the engineering data is bound with the BIM model, so that only the relation is changed, and the data model does not need to be refilled, so that the labor is reduced, and meanwhile, the error is avoided.

In an optional manner of this embodiment, determining, in the scene model map of the engineering stage, a correspondence between each model component node in the core model map and the engineering data node includes: acquiring a global unique identifier of each model component in a building information model of the engineering stage; and determining the corresponding relation between each model component node and the engineering data node in the core model diagram in the scene model diagram of the engineering stage according to the global unique identifier.

Where the globally unique identifier refers to a unique identifier (GUID, globally Unique Identifier) in the IFC file that is used to identify the model component.

In the building process of the building information model, a global unique identifier is allocated to each model component in the building information model, and the global unique identifier is a digital identifier. Because the globally unique identifier is used for representing the model component, the engineering data can be divided according to engineering data types, and the engineering data types are model components, the globally unique identifier can be used as an intermediary, and the corresponding relation between each model component node and the engineering data node in the core model diagram is determined in the scene model diagram of the engineering stage so as to establish the association between each model component node and the engineering data node. The schematic organization of the core model map and the scene model map is shown in fig. 8, wherein the core model represents the core model map and the scene model represents the scene model map.

In this embodiment, the global unique identifier is pre-allocated in the building information model and is a unique identifier of a model component, and the corresponding relationship between each model component node and the engineering data node in the core model diagram is determined in the scene model diagram of the engineering stage by the global unique identifier, so that the association between each model component node and the engineering data node can be accurately and rapidly established.

In one embodiment, the shared data includes shared data in a core model graph and shared data in a scene model graph; the updating processing of the shared data comprises the following steps: carrying out refinement treatment on shared data in a core model diagram in the shared data; and adding attribute fields to the shared data in the scene model diagram in the shared data, and constructing an association relationship between the attribute fields and the building information model in the core model diagram in the scene model diagram.

Geometric data and attribute data in the core model diagram can be continuously refined along with project advancement, and information and data of different scenes in different stages are circulated, which is essentially that the data model diagram is continuously updated and inherited in the process of engineering so as to adapt to requirements of different stages, and meanwhile, the influence of redundancy of the data on the use of the data model is avoided.

And for each engineering stage of the power transformation project, acquiring shared data in a core model diagram, and carrying out refinement treatment on the shared data in the core model diagram, wherein the refinement treatment can specifically comprise refinement treatment of civil engineering facility information and electrical equipment information, unidirectional supplementation and refinement can be carried out on the model aiming at the civil engineering facility information, and installation and debugging information of the electrical equipment can be updated and perfected aiming at the electrical equipment information.

Obtaining shared data in the scene model graph, the circulation of the shared data in the scene model graph needs to ensure that the added attribute names remain consistent throughout the life cycle. A specific update procedure may be to add attribute fields to the shared data in the scene model graph. The shared data is also engineering data, so that it is necessary to link the shared data to the model components. The data stored in the independent part of the scene model diagram is only reserved in the data model of the current stage, and does not flow to enter the next stage. The flow rules for the data model graph are shown in Table 3 below, where the data model represents the data model graph:

TABLE 3 data model flow rules

Optionally, during data circulation, redundant data removal can be performed on shared data in the data model diagram, where the shared data includes geometric data, attribute data and engineering data. After the redundant data is removed, the attribute data may be removed simultaneously. Therefore, the attribute integrity comparison needs to be performed on the data model according to the scene requirement of the next engineering stage, and if the attribute is incomplete, the missing attribute needs to be added.

In this embodiment, the data use cost of the power grid project can be reduced, the data transfer capability can be improved, and the work tasks of each stage of the project can be better assisted by removing redundant data from the source end of the previous project stage, comparing the attribute integrity, improving the granularity of geometric information to the next project stage, and the like.
