The automatic low-voltage area map mapping device comprises a data loading component, an area map layout and wiring component and an area map storage component, wherein the data loading component is connected with a power grid GIS platform and is used for loading low-voltage edge layout data of the power grid GIS platform and generating an intermediate memory data structure; the platform area diagram layout and wiring assembly is based on the intermediate memory data structure, creates a platform area diagram organization structure and all circuit equipment entity objects of the platform area diagram, and creates an association relation with a layout and internal wiring diagram source object in low-voltage edge layout data to generate a low-voltage platform area diagram; the station area diagram storage component is used for storing the low-voltage station area diagram.
In this embodiment, the low-voltage station area diagram automatically generates the required basic data including substation room data, low-voltage line data and low-voltage station room data, and correspondingly, the data loading component includes a substation room loading sub-component, a low-voltage line loading sub-component and a low-voltage station room loading sub-component, loads the substation room data, the low-voltage line data and the low-voltage station room data to the low-voltage station area diagram automatic mapping device of this embodiment through connection with the power grid GIS platform, and generates an intermediate memory data structure, where the intermediate memory data structure includes a memory object model for subsequent automatic mapping.
Referring to fig. 3, the low-voltage edge layout and the station house internal diagram are respectively displayed in the power grid GIS platform, and the edge layout line equipment and the station house internal equipment are communicated through 'in-station and out-of-station connection', so that the condition of the integral connection of the station area is not beneficial to being seen on one diagram. By carrying out topological fusion and simplification on the layout low-voltage line model and the station house internal line diagram model, the station house internal diagram is unfolded on the layout, non-key equipment such as a low-voltage lever tower is properly simplified and filtered, and an abstract topology is formed, so that the purposes of conciseness and visual display can be achieved, and efficient mapping processing of a subsequent automatic generation process is supported. The simplified effect diagram of the fusion of this embodiment is shown in fig. 4.
The platform region diagram layout and wiring component receives the intermediate memory data structure of the data loading component, creates a platform region diagram organization structure and all circuit equipment entity objects of the platform region diagram on the basis of the intermediate memory data structure, and creates an association relation with the source objects of the layout and internal wiring diagrams in the low-voltage edge layout data to generate the low-voltage platform region diagram. In the process of generating the low-voltage area diagram by the area diagram layout and wiring component, some generation parameters can be set so as to realize personalized customization of the low-voltage area diagram. In addition, the method of generating the low-voltage area map by the area map layout and wiring assembly in the embodiment is two, one is initialization generation, and the other is incremental update generation. The low-voltage area map generated by the automatic low-voltage area map generating device of the embodiment is stored in the area map storage component database, each transformer corresponds to one low-voltage area map according to service application requirements, before the area map layout and wiring component executes generating actions, whether the area map of the transformer exists or not can be judged according to the transformer corresponding to the area map, if not, the generation is initialized, and if so, the incremental updating is performed.
