Abstract: In order to improve the convenience and efficiency of information management for each communication station in a power supply bureau, this paper designs and develops a vector graph editing system for power optical fiber communication network. This system not only has the common operating functions of creating, deleting, selecting, scaling, moving and Undo/Redo, but also realizes the bidirectional data configuration function of graphics object by establishing the association with relational database. In order to improve the editing efficiency of vector graphics, we propose an algorithm for dynamic generating of broken lines by analyzing the position relationship of communication station objects connected to each other in vector graphics. The results of the test show that the designed system is stable, convenient and efficient, and can meet the requirement of vector drawing of electric power optical fiber communication network.
