Graphical display method of interface information of assemblies of complex electronic equipment

The invention discloses a graphical display method of interface information of assemblies of complex electronic equipment. The method comprises steps as follows: a system receives a user instruction, reads data in a database, assembles assemblies, interfaces and cable graphs according to the data type, displays the graphs on a window with a layout algorithm and expresses the topological connection relation among the assemblies of the electronic equipment, the interfaces and cables in a graphic manner, graph items can receive the user instruction, and the system further reads the database, displays assemblies, interface electrical information, fault detection and other information in a form manner and assists in fault maintenance. Cable connection graphs and connection tables are required to be looked up during maintenance of the complex electronic equipment and looked up in paper maintenance materials such as atlases and the like manually in the traditional method, lookup is time-consuming and labor-consuming
