工业现场控制网络数据动态交换技术的研究

A study on data exchanging in computer networks in industrial environment

从不同角度对 Net DDE、Winsock和 DCOM这三种常用数据动态交换技术做了详细对比分析 ,指出各自的优缺点 ,给出了他们的实现方法 .同时 ,对这三种数据动态交换技术做了试验和验证 。

The key technique is how to realize the dynamic data exchanging efficiently among computers in a computer network for industrial control systems. At present time, there are three techniques, NetDDE, Winsock and DCOM, for dynamic data exchanging in a computer network. This paper analyses these three techniques from different angles, compares theirs characteristics between each other, points out theirs advantages and disadvantages and presents methods for realizing the techniques. These three techniques are tested and verified in computer networks. These three techniques are successfully applied to the airport light monitoring and control system for the Hang Zhou Xiao Shan airport.
