Distribution Network Based on AutoCAD to FIG line diagram of the method of automatic conversion

The invention discloses an automatic distribution network diagram to single line diagram conversion method based on AutoCAD. Particularly, in automatic large-medium distribution conversion systems, an AutoCAD diagram designed by a distribution designer is automatically converted into a scheduling single diagram and a system diagram which are used by a dispatcher in an automatic distribution system by adopting layered conversion and layered display methods, different kinds of information of a background layer, an equipment layer and an equipment labeling layer is selectively converted and displayed according to the dispatching, operating and maintenance requirements, and a diagram topologic connection relation is automatically generated. By adopting the method, the efficiency of the automatic distribution system in project implementation and system secondary maintenance can be greatly improved, the workload of a single line diagram maintainer is greatly reduced, and a powerful technical support is provided for the distribution project implementation, dispatching, operating and maintenance.
