| In order to achieve a convenient man-machine interaction for grounding grids corrosion diagnosis software, a grounding grids topology input edition approach is proposed. A edge edition table with four columns and a node edition table with three columns are introduced to record the processes of input. The operations of adding, eliminating and changing the types of nodes are detailed. The approaches of eliminating redundancy records, compression the sequence numbers of nodes and edges and establishing the relevancy matrix of nodes to branches are described. A grounding grid is used as an example to show the proposed methodologies, the results of which show the feasibility of the proposed approaches.In the process of grounding grids corrosion diagnosis, the original Network topology was broken down into five different structure after hierachical. In order to achieve a variety of topology model, this paper based on multi-view creation method of VC + + , a creation method that a multi-view format is proposed and satisfied a variety of grounding grid model for the display . The method that based on the final results of hierachical---Intrinsic Grounding Grid Network topology to achieve a Intrinsic Grounding Grid modeling approach in a new view .Meanwhile, in the model to solve the existence of serious overlap of the branch solution, achieving intrinsic grounding of the model is automatically created. Intrinsic grounding grid in two model building as an example of the validation results show that the proposed method is convenient and feasible.On the basis of the principle, an application software is developed based onVC++6.0. The software has a good human-machine interaction, and use of graphical in-put techniques, can be a flexible model of grounding grids editor, obtained convenient and intuitive diagnostic results. Test results show that the software and the results fully consistent with the theoretical values.
