TECHNICAL FIELD
[0001] The present application relates to the technical field of knowledge graph, and particularly relates to a visual display method of power knowledge graph. BACKGROUND
[0002] In the power industry, some related enterprises have adopted knowledge graph technology to build a digital power grid model, which is called a power knowledge graph. At present, the visual display of the power knowledge graph is in a unified fixed layout mode, that is, everyone sees the same power knowledge graph. This display mode has a defect that different personnel of different identities are concerned about different equipment or power grid data. For example, transformer operation and maintenance team personnel only need to understand the operation of the transformer in the power grid system through the power knowledge graph, and high-voltage circuit breaker operation and maintenance team personnel only need to understand the operation of the high-voltage circuit breaker in the power grid system. In this case, the transformer operation and maintenance team personnel and the high-voltage circuit breaker operation and maintenance team personnel need to find the equipment they are concerned about in the power knowledge graph by themselves. Since the power knowledge graph contains a large number of power equipment, it is troublesome and time-consuming for users to find. SUMMARY
[0003] The technical problem to be solved by the present application is to provide a visual display method of power knowledge graph, which can display different knowledge graph layouts for different users and facilitate users to quickly find the knowledge they want to understand.
[0004] In order to solve the above technical problem, the present application provides a visual display method of power knowledge graph, comprising the following steps:
[0005] Step A. Taking power equipment and personnel as object instances, constructing a power knowledge graph according to the object instances and the association relationship therebetween;
[0006] Step B. If a power knowledge graph display instruction input by a user is received, the account information of the user is obtained;
[0007] Step C. The personnel object instance corresponding to the user is determined according to the account information of the user;
[0008] Step D. The personnel object instance corresponding to the user and its associated object instances are adjusted to the center area of the power knowledge graph;
[0009] Step E. The adjusted power knowledge graph is displayed to the user.
[0010] Further, in step E, the personnel object instance corresponding to the user and its associated object instances are highlighted in the adjusted power knowledge graph.
[0011] Further, in step E, the highlighted manner includes color marking or bold marking.
[0012] Further, in step D, the personnel object instance corresponding to the user is specifically adjusted to the center position of the graph, and the associated object instances are adjusted around the personnel object instance in a snowflake layout.
[0013] Further, in step E, the center area of the power knowledge graph is specifically enlarged to fill the screen, so that only the personnel object instance corresponding to the user and the associated object instances are displayed, and the remaining object instances of the power knowledge graph are not displayed.
[0014] Further, the method comprises step F. If a user inputted zoom-out instruction is received, the power knowledge graph is zoomed out to display the center area and at least part of the non-center area together on the screen, so that the remaining object instances located in the non-center area are displayed.
[0015] The visualization display method of the power knowledge graph provided by the present application can automatically display the personnel object instance corresponding to the user and the associated object instances to the center area of the power knowledge graph when the user views the power knowledge graph, so that the power knowledge graph layouts viewed by users with different roles are different, and all users can see the knowledge they want to understand in the center area of the power knowledge graph, which is convenient and fast.

[0020] The present application will be further described in detail below in combination with specific embodiments.
[0021] As shown in Figure 2 , the visualization display method of the power knowledge graph provided by the present application comprises the following steps:
[0022] Step A. Taking power equipment and personnel as object instances, a power knowledge graph is constructed according to the object instances and the association relationship therebetween.
[0023] The power knowledge graph is constructed by taking the construction of a substation knowledge graph as an example. The names of all power equipment in each substation and the association relationship therebetween are listed by the staff in advance, and the names of personnel responsible for the operation and maintenance, dispatching and other work of the related power equipment and the association relationship therebetween are listed, and then all power equipment object instances and personnel object instances are constructed according to the above association relationship, and the relationship edges between the object instances are constructed, thereby constructing the substation knowledge graph (which belongs to one of the power knowledge graphs).
[0024] Step B. If a power knowledge graph display instruction input by a user is received, the account information of the user is obtained.
[0025] The constructed substation knowledge graph is saved on the power grid knowledge graph platform for relevant personnel of the power grid enterprise to review. Since different personnel of different identities are interested in different equipment, for example, the transformer operation and maintenance team personnel only need to understand the operation of the transformer in the power grid system through the power knowledge graph, and the high-voltage circuit breaker operation and maintenance team personnel only need to understand the operation of the high-voltage circuit breaker in the power grid system. Therefore, when a power knowledge graph display instruction input by a user is received, the account information of the user is obtained, and the name of the user is determined accordingly. For example, transformer operation and maintenance team personnel Zhang San logs in the power grid knowledge graph platform through his own account and inputs a substation knowledge graph display instruction (i.e. a power knowledge graph display instruction). After the power grid knowledge graph platform receives the substation knowledge graph display instruction input by Zhang San, the account information of Zhang San is obtained, and it is determined that the name of the user is Zhang San.
[0026] Step C. The personnel object instance corresponding to the user is determined according to the account information of the user.
[0027] After the power grid knowledge graph platform determines that the name of the user is Zhang San, it is determined that the personnel object instance corresponding to the user is Zhang San.
[0028] Step D. The personnel object instance corresponding to the user and the associated object instances thereof are adjusted to the center area of the power knowledge graph.
[0029] In this embodiment, Zhang San is a transformer operation and maintenance team personnel and is responsible for the operation and maintenance of the transformer in the substation, so the associated object instance thereof is the transformer object instance. After the power grid knowledge graph platform determines that the personnel object instance is Zhang San, the personnel object instance Zhang San is adjusted to the center position of the graph as shown in Figure 2 , and the transformer object instance associated with Zhang San is adjusted around Zhang San in a snowflake layout with Zhang San as the center.
[0030] Figure 2 The substation knowledge graph shown is a graph layout specially adjusted for Zhang San. If a substation knowledge graph display instruction is input by other personnel, the layout of the substation knowledge graph will change accordingly, unlike the substation knowledge graph shown. Figure 3 For example, Wang Wu who is responsible for the operation and maintenance of fuses and high-voltage circuit breakers logs in to the power grid knowledge graph platform through his own account and inputs a substation knowledge graph display instruction. After receiving the substation knowledge graph display instruction input by Wang Wu, the power grid knowledge graph platform obtains the account information of Wang Wu, and accordingly determines that the user name is Wang Wu, and the personnel object instance corresponding thereto is Wang Wu, as shown in Figure 2 The personnel object instance Wang Wu is adjusted to the center position of the graph, and the fuse object instances and high-voltage circuit breaker object instances associated with Wang Wu are adjusted around Wang Wu in a snowflake layout with Wang Wu as the center.
[0031] Step E. Display the adjusted power knowledge graph to the user.
[0032] The power grid knowledge graph platform can display the adjusted substation knowledge graph to the user. However, since a substation knowledge graph can include many object instances, if the complete substation knowledge graph is directly displayed, the display screen will be filled with densely packed object instances, which is not convenient for the user to directly view the object instances that he or she wants to understand. Therefore, in this embodiment, when the adjusted substation knowledge graph is displayed, the central region of the substation knowledge graph (see the region within the dashed circle in Figure 3 or the region within the dashed circle in Figure 4 ) is enlarged to fill the screen (see Figure 2 ), so that only the personnel object instance (Zhang San) corresponding to the user and the associated object instances (transformer object instances) are displayed, and the remaining object instances of the substation knowledge graph are not displayed, so as to facilitate the user to directly view the object instances that he or she wants to understand.
[0033] Alternatively, when the complete substation knowledge graph is displayed, the central region of the substation knowledge graph can be highlighted by bold annotation, so that the personnel object instance (Zhang San) corresponding to the user and the associated object instances (transformer object instances) are highlighted as shown in Figure 2 . The highlighting method can be changed to color annotation.
[0034] Step F. If a zoom-out instruction input by the user is received, the power knowledge graph is zoomed out to display the central region and at least part of the non-central region together in the screen, so that the remaining object instances located in the non-central region are displayed.
[0035] In this embodiment, the central region of the substation knowledge graph (seeFigure 3 or Figure 2 the area within the dashed circle in FIG. 11B) to the full screen, so that only the personnel object instance (Zhang San) corresponding to the user and the associated object instance (the transformer object instance) are displayed without displaying the remaining object instances of the substation knowledge graph. If Zhang San needs to know other object instances in the substation knowledge graph, a zoom-out instruction can be input. After the power grid knowledge graph platform receives the zoom-out instruction, the substation knowledge graph is zoomed out to display all the object instances in the screen, i.e., to display the complete substation knowledge graph as shown in FIG. 11A, so that the remaining object instances located in the non-central area are displayed. In addition, the substation knowledge graph can also be zoomed out to display only the central area and part of the non-central area instead of directly displaying the complete substation knowledge graph.
[0036] The above description is only an embodiment of the present application, and does not limit the patent protection scope. Those skilled in the art can make non-essential changes or substitutions on the basis of the present application, and still fall within the patent protection scope.
