摘要
在工业计算机网络中要实现对制造过程的监视、控制和管理,计算机间数据动态交换是关键。介绍了Winsock和DCOM这两种常用的数据动态交换技术在网络监控系统中的应用,并从不同角度对它们作了详细的比较与分析。指出基于Winsock技术的系统具有开发方便、可靠性高、实时性强等优点,但也存在着多种数据交换复杂等不足,故仅适用于一般性的工业控制网络。而COM/DCOM作为一种基于组件对象模型的分布式技术规范,因其独特的标准、结构、特点,为大型复杂的网络监控系统设计开发提供了有效的工具。
The key technique is how to realize the dynamic data exchanging efficiently among computers in a computer network for industrial control system.Introduced the application of Winsock and DCOM in network style monitoring system and analysed the two techniques from different parts.Pointes out that the monitoring system based on Winsock has high reliability,high transmission speed and collection of great amount of data can be satisfied.But it has some shortcomings.So it is suited to ordinary monitoring system.COM/DCOM has excellent criterion,structure and characteristic.It is an effective method to develop complicated monitoring system.
