低成本控制与管理网络数据通信系统的设计与应用

Design and Application of a Low Cost Communication System Between Control Network and Management Network

探讨了实现Rosemount DeltaV DCS与PC LAN间数据传输的原理和方法,重点讨论了通信系统的构成、软件的设计思路和通信系统的应用。提出的解决方案具有系统结构简单、可靠性高、实施成本低的特点,设计思路适合于其它控制网络与管理网络间的数据通信。此研究结果已应用于一大型石化装置的生产调优系统开发中,取得了较为理想的效果。

A method of data transfer between Rosemount DeltaV DCS and PC LAN is discussed . The study focuses not only on the system architecture and software design procedures of communication between the DCS and PC LAN but also on the application of the communication system. The raised solution possesses simple structure, high reliability and low cost, which can be applied in other communication system between control network and management network. The study of this paper has been used in an industry application for the development of production optimization system, and the result is satisfactory.
