Detailed Description
The invention will be described in further detail with reference to specific embodiments.
As shown in fig. 1, the method for visually displaying the power knowledge graph provided by the invention comprises the following steps:
and step A, taking power equipment and personnel as object examples, and constructing a power knowledge graph according to the object examples and the incidence relation between the object examples.
In this embodiment, the process of constructing the power knowledge graph is described by taking the transformer substation knowledge graph as an example: the method comprises the steps that a worker lists names of all power equipment in each transformer substation and incidence relations among the power equipment in advance, lists names of workers in charge of operation, maintenance, scheduling and the like of the related power equipment and incidence relations among the workers and the power equipment, constructs all power equipment object examples and all personnel object examples according to the names and the incidence relations, and constructs relation edges among the object examples according to the incidence relations, so that a transformer substation knowledge graph (belonging to one of the power knowledge graphs) is obtained.
And B, if a power knowledge graph display instruction input by a user is received, acquiring account information of the user.
The constructed transformer substation knowledge graph is stored on a power grid knowledge graph platform and is retrieved by related personnel of power supply network enterprises. Due to the fact that personnel with different identities are concerned, equipment is different, for example, personnel of a transformer operation and maintenance team only need to know the operation condition of a transformer in a power grid system through a power knowledge graph, and personnel of a high-voltage circuit breaker operation and maintenance team only need to know the operation condition of a 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 acquired, and the name of the user is determined according to the account information. For example, zhang III of the transformer operation and maintenance team personnel logs in a power grid knowledge graph platform through own account number and inputs a transformer substation knowledge graph display instruction (namely a power knowledge graph display instruction), and after the power grid knowledge graph platform receives the transformer substation knowledge graph display instruction input by Zhang III, the account number information of Zhang III is obtained, and accordingly it is determined that the user name is Zhang III.
And C, determining a corresponding personnel object example according to the account information of the user.
After the power grid knowledge graph platform determines that the name of the user is Zhang III, the person object example corresponding to the user is Zhang III according to the determination result.
And D, adjusting the personnel object examples and the related object examples corresponding to the users to the central area of the power knowledge graph.
In this embodiment, zhang san is a transformer operation and maintenance team member responsible for operation and maintenance of the transformer in the transformer substation, and therefore the associated object instance is a transformer object instance. After the power grid knowledge graph platform determines that the number of the personnel object instances is Zhang III, as shown in fig. 2, the Zhang III of the personnel object instances is adjusted to the center position of the graph, and the transformer object instances related to the Zhang III are adjusted to the periphery of the Zhang III according to the snowflake type layout by taking the Zhang III as the center.
The substation knowledge graph shown in fig. 2 is a graph layout specially adjusted for Zhang III, and if other personnel input a substation knowledge graph display instruction, the layout of the substation knowledge graph changes correspondingly, which is different from the substation knowledge graph shown in fig. 2. For example, the king five responsible for operating and maintaining the fuse and the high-voltage circuit breaker logs in a power grid knowledge graph platform through own account numbers and inputs a substation knowledge graph display instruction. After the power grid knowledge graph platform receives a transformer substation knowledge graph display instruction input by the King five, the account information of the King five is obtained, the user name is the King five according to the account information, the corresponding personnel object example is the King five, as shown in fig. 3, the personnel object example King five is adjusted to the graph center position, the King five is used as the center, and the fuse object example and the high-voltage circuit breaker object example related to the King five are adjusted to the periphery of the King five according to snowflake layout.
And E, displaying the adjusted power knowledge graph to a user.
After the substation knowledge graph layout is adjusted by the power grid knowledge graph platform, the substation knowledge graph can be displayed to users, but because one substation knowledge graph may contain a plurality of object examples, if the complete substation knowledge graph is directly displayed, dense and hemp object examples can be fully paved on a display screen, and it is inconvenient for the users to directly view the object examples which the users want to know.
Alternatively, when the complete substation knowledge graph is displayed, the central area of the substation knowledge graph may be highlighted by bolding, so that the person object instance (zhang) and the associated object instance (transformer object instance) corresponding to the user are highlighted as shown in fig. 2. The manner of highlighting may instead be by color marking.
And F, if a reduction instruction input by a user is received, reducing the power knowledge graph to the central area thereof and displaying at least part of the non-central area together in the screen, so that the rest object examples positioned in the non-central area are displayed.
In the embodiment, the central area of the substation knowledge graph (see the area in the dotted circle in fig. 2 or fig. 3) is enlarged to the full screen, so that only the personnel object instance (zhang san) corresponding to the user and the associated object instance (transformer object instance) thereof are displayed, and the rest object instances of the substation knowledge graph are not displayed. If Zhang III needs to know other object examples in the transformer substation knowledge graph, a reduction instruction can be input. After the power grid knowledge graph platform receives the reduction instruction, the transformer substation knowledge graph is reduced until all object examples are displayed on a screen, namely, the complete transformer substation knowledge graph shown in fig. 2 is displayed, so that the rest object examples located in the non-central area are displayed. In addition, the substation knowledge graph can be reduced to only display a central region and a part of non-central regions instead of directly displaying the complete substation knowledge graph.
The above description is only an embodiment of the present invention, and the scope of protection is not limited thereto. The invention is not limited to the above embodiments, but may be modified within the scope of the appended claims.
