具有组态功能的光纤通信网络图编辑系统设计

为了提高某供电局对各通信站进行信息管理的便利性和高效性，设计开发一个针对电力光纤通信网络的矢量图编辑系统。该系统不但具有图形对象的创建、删除、选择、缩放、移动、Undo/Redo等常用的编辑功能，而且通过建立与关系数据库的关联，实现对图形对象的双向数据配置功能。为了提高矢量图形的编辑效率，通过分析矢量图中相互连接的通信站对象的位置关系，提出一种折线动态生成算法。测试结果表明，所设计的系统稳定、方便、高效，可满足电力光纤通信网络矢量图的绘制需求。

Design of Optical Fiber Communication Network Diagram

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.
