The invention aims to provide an automatic distribution network AUTOCAD design drawing identification method. The method can automatically import the distribution network design drawings in a CAD format into a GIS system, and then identify various devices of the distribution network in the GIS system. The method comprises two processes: creation of a sample database and identification of the devices in the CAD design drawings. The automatic distribution network AUTOCAD design drawing identification method, disclosed by the invention, can automatically identify the devices in the CAD design drawings with high identification rate; as the CAD design drawings and device identification are processed automatically by a program, the method is faster in processing speed and more convenient, and meanwhile solve the problem that the manual manner causes inaccurate data.
