Abstract:

The graphical interface is one of the basic components of the monitoring configuration software, which has a great impact on the software. However, a variety of configuration software currently used different graphic styles to form the monitor screen, so that different systems interact difficultly. To overcome this shortcoming and improve the reusing rate of code writing monitor screen and enhance applications efficiency of dealing with a lot of graphics information, this paper sets up a monitoring graphics elements library of configuration software, which uses SVG recommended by the international image formats of monitoring interface, and elaborates the way to define equipment element property. Integrating Batik project of ASF (Apache software foundation) and adopting Object Orient Design Thought, the paper analyses and designs the monitoring graphics elements library module of configuration software. Configuring graph's properties as the corresponding with relational SQL datebase which facilitate the programmer inputs data, can improve the total level of the configuration software.

Key words: The configuration software, SVG, Interface, The graphics elements library

摘要： 图形界面是构成监控组态软件的基本组成部分之一,对于该软件具有很大的影响。当前各种组态软件使用各自不同的图形样式来形成监控画面,使不同的软件系统间交互困难。为了克服这个缺点,提高编写监控画面的代码复用率,增强应用程序处理大量图形信息的效率,提出了建立监控组态软件的图形元素库,该库使用的是由国际标准推荐的SVG监控界面标准图片格式,并定义了设备单元属性的方式。同时,结合具有面向对象设计思想的ASF蜡染工程,研究和设计了组态软件监控图形元素库模块。并通过配置图元属性,与关系型SQL数据库对应,方便程序员录入数据,提高组态软件的总体水平。
