摘　　要：分布式高炉专家系统的一个重要特征实时性通常表现在三方面:(1)对高炉状态的变化作出实时反应;(2)系统各组成部分之间的实时调度;(3)当专家系统的运行结果在网上发布时,所有客户都能够实时地收到更新通知。文中分别采用基于TCP/IP协议的Socket技术、Windows消息机制和DCOM技术来实现上述要求。实验表明系统具有良好的实时性。Real-time characteristic takes an important part in distributed expert system for blust funace. Usually these characteristics can be reflected in three ways. The first way is that the system must respond to the blast furnace＇s state changing in time. The second is that the system must schedule all of its subsystems correctly. The third is that when the system punish its results on internat or internet, it must have the ability to notify all the browsers whennever it updated the results. To satisfy the system＇s requirement, This paper introduce the socket technology of TCP/IP protocol, the Windows＇s message mechanism and the DCOM technique. The practical result has indicated our system has good real-time characteristics.
