The smart label technology in intelligent substation adopts the smart label on the scanning cable to visualize the connection between the real circuit and the virtual circuit, and adopts the private database as the data source of the intelligent label visualization application. Two aspects are optimized. In the aspect of smart label data source, the data source of the panoramic model file is used instead of the private database format. In the label generation configuration process, the light panorama model configuration tool is used instead of the secondary system design, i.e. the software configures the mode of physical information flow and SCD files. The panoramic model file includes the real loop model file and the virtual loop model file. The physical port in the two model files realizes the "virtual reality correspondence" and the virtual reality mapping. Using optimized technology is conducive to the secondary system design software product exchange interoperability; intelligent tag data processing is conducive to the standardization and uniform, saving the smart tag production time.
