Problems solved by technology

When the local graphic data changes, the resulting changes are also local, but professional GIS personnel are still required to reconstruct the entire topological topic, which makes the establishment and maintenance of spatial data structures based on topological relationships quite expensive, and at the same time Great inconvenience to users

Embodiment Construction

[0032] Embodiments of the present invention are further described below:

[0033] like figure 1 Shown, the geographical diagram based on GIS diagram of the present invention, the planning graphic automatic conversion method of electrical wiring diagram, comprises the following steps:

[0034] (1) Build a distribution network line model through the GIS system, so that the distribution line forms a directed tree with the source point as the root;

[0035](2) Taking the end point of the line and the tie switch as the end points, the branches are classified according to the spatial position and the number of nodes contained, and a distribution line is decomposed into a set composed of several branches at all levels;

[0036] The above-mentioned one distribution line is decomposed into a 0-level branch, several 1-level branches, several 2-level branches, and so on to several N-level branches, where N is greater than or equal to 1;

[0037] (3) According to the distribution networ...

Abstract

The invention relates to a method for automatically converting a planning graphic of a geographical wiring diagram and an electrical wiring diagram based on a GIS map, and belongs to the technical field of power grid planning. The method comprises the steps that a distribution network line model is constructed through a GIS system so as to enable a distribution line to form a directed tree taking a source point as the root; the end point of the line and contact switches are enabled to act as endpoints, grading is performed according to the spatial position and the number of contained nodes, and the distribution line is broken into a set formed by a plurality of branches at all levels; a horizontal and vertical electrical wiring diagram is generated for the broken branches at all levels of the distribution line according to the distribution network line model. According to the invention, automatic conversion from the geographical wiring diagram to the electrical wiring diagram can greatly reduce the data maintenance workload of the whole system, avoids repeated configuration of the data and can ensure the consistency of the data.

Description

technical field [0001] The invention relates to a method for automatically converting planning graphics based on geographic maps and electric wiring diagrams of GIS maps, and belongs to the technical field of power grid planning. Background technique [0002] Geographic wiring diagrams and electrical wiring diagrams are indispensable graphic materials in the operation of power systems. The geographic wiring diagram is the necessary spatial data to realize the geographic information system (GIS). The electrical wiring diagram is the interface of the SCADA system to display the real-time operation information of the distribution network. [0003] At present, geographic wiring diagrams and electrical wiring diagrams are manually edited and generated on the GIS system and SCADA system platform respectively, and there are hidden dangers of inconsistent data and graphic configurations. The automatic conversion of geographic wiring diagrams to electrical wiring diagrams will great...
