摘　　要：随着网络化的日益普及 ,现有计算机系统面临着复杂和难以集成的问题 .以 CORBA为主流技术的分布对象计算技术简单有效地降低了非实时应用的复杂度和集成难度 .但是 ,现有的 CORBA规范无法支持分布实时环境 ,因此 ,有必要研究基于 CORBA的分布实时对象计算技术 .本文分析了现有 CORBA规范的实时特性缺陷 ,以作者设计的基于 CORBA的分布实时对象计算软件 ORBase为例 ,介绍了基于 CORBA的分布实时对象计算的关键技术及其实现 ,为以 CORBA为代表的分布对象计算技术在实时领域的应用和推广做出了有益的尝试 .The computer network becomes more and more popular, which leads to the construction and integration of computer systems to become more and more complex and difficult. The distributed object computing, whose mainstream technology is Common Object Request Broker, has the nature ability to reduce the complexity and difficulty of non real time applications development. Unfortunately, the current CORBA cannot support the real time environment that is very important in the distributed computing. This paper analyses limitations of CORBA in real time applications, and then presents the research of the key technologies in the CORBA based distributed real time object computing, while introduces the implementation of these technologies in ORBase which is a large CORBA based distributed real time object computing software designed by authors. The achievements of this paper are very helpful and useful to improve the CORBA applications in the real time domain.
