摘要
传统的面向对象的编程技术,对象与访问该对象的程序只能存在于同一进程中,外部进程无法了解和访问这些对象。提出一种基于CORBA技术的分布式对象模型的电力监控系统的软件设计思路,结合命名服务及CORBA回调技术实现电力监控系统的实时响应性和安全可靠性,最后介绍了系统的整体结构框架和模型,该框架具有良好的可重用性、可移植性、可扩展性和互操作性。并在实践基础上提出对CORBA技术应用的展望,希望寻找一种更适合分布式电力监控系统的通信方法。
An application can＇t interact with object resides otherwhere on network in traditional object-orient programming. A distributed object supervisory control system based on CORBA technology is proposed. This paper carries out the real time response and safety reliability in supervisory control system by adopting multithread combining naming service and callback technology of CORBA. Finally, it expatiates the whole system configuration frame and model. This frame has good characteristic that can be duplicated, transplanted, expanded well. This paper explores the CORBA technology foreground in practice, and hopes to fred a better communications mode of distributed electric supervisory control system.
