As the power grid enterprises grow, the relationship between their power grid systems is becoming closer and closer. In the context of industrial development with the energy structure unbalanced, The operation of the power grid becomes more and more complicated, making the power grid system face the technical problems. In this context of technological development, power grid enterprises should follow the pace of the times and integrate intelligent technology into the technological innovation of the power grid to make the ability to predict the power grid fault come true in advance, and the grid map intelligent identification technology is the key technology to support the power grid enterprise to realize informatization and intellectualization. Because most of the original data of the power grid enterprise are stored in various kinds of power grid design drawings, the power grid intelligent identification technology can effectively visualize the data of such power grid drawings, and then realize the intellectualization which early warning technology means.
