“VXI总线测试软件平台”主框架的设计

The Architecture Design of the VXIbus Based Test Software Platform

利用面向对象的编程方法 (OOP)和C ++的封装(Encapsulation)、继承 (Inheritance)和多态性 (Polymor phism)来建立功能完善的控件基类。实现控件各种属性设置、用户仪器测试程序的序列化存储、控件的数据流和控制流的分离 ;利用连线实现数据驱动和控制驱动 ;VXI总线测试软件平台运行机制是利用Windows的消息驱动和支持多线程机制来实现用户测试软件的执行和调试。

With the methodology of object oriented programming (OOP),C++ encapsulation, inheritance and polymorphism ,a powerful basic component class is constructed.It is the main task of the architecture design to define components' properties,to serially store user test programs,to detach the data flow from control flow and to drive the data and control by lines.The VXIbus based test software platform employs the mechanism of message driving and multithreads provided by Windows operation system to debug and execute users' programs.
