基于构件的地面轨道电路信息管理系统

Track Circuit Information Management System Based on Component

在面向对象的基础上 ,引入了软件复用的概念 ,对软件构件的三个典型模型进行了比较分析 ,并利用其中的COM /DCOM模型 ,实现铁路轨道电路信息管理系统 .以软件构件理论为基础 ,本着开放性、可维护性、友好性、可扩展性的原则 ,采用面向对象技术 ,在系统级上解决并实现了软件可重用性 ,提高了软件开发的效率和质量 ,并在Windows 98操作平台上用VisualC + +实现了系统主要部分的编码工作 .在充分研究软件构件理论的基础上 ,利用面向对象技术来实现系统的各主要功能及数据的信息封装 .这使得本软件系统能与外部设备相适应发展 ,也能让用户对其进行二次开发 。

Based on object oriented the software reuse conception is introduced. Compared and analyzed the three software component models, then selected COM/DCOM model as the programming method. Using COM/DCOM model, the railway signaling testing management system is complemented. The main idea is software component theory and application in this paper. The advantage of the system is opening, maintainable, friendly and expandable. Using OOP technique to analyze and design the railway signaling information testing management system, improving quality in the software development and realizing the software reuse. Using Visual C++ to complete coding based on Windows 98 flat. Object oriented technique offers a very important function and encapsulation for the system. It makes the software system can acclimatize to exterior equipment. Moreover, it is convenient for users to employer the software further; therefore it prolongs the life span of the software.
