摘要
EJB技术是Sun公司近几年提出的建立在J2EE平台上的分布式系统的标准,它实现了跨平台,为构造工业分布式控制系统提供了新途径。本文先介绍了分布式控制系统的模型和工作原理以及基于EJB技术的分布式计算的工作原理,首次研究了采用EJB技术来构造工业分布式控制系统的方法,给出这种新方法的实现过程,最后讨论了这种方法的一些特点,分析了其实时性能。
The EJB(Enterprise Java Bean)technolog y is a distributed system standard which has been devel-oped by Sun Corporation during last years.It realizes the cross -operation platform,provides a new solution for constructing an industrial distributed control system.In this paper,the model and principles of distribut-ed control system as well as the working principle of EJB technolog y are introduced.The method of con-structing an industry distributed control system with EJB is studied,and the realizing procedure is g iven.The characteristics of the new method and its real-time performance is analyzed and discussed also.
