石油化工工厂网络系统的一体化设计与实现

INTEGRATED DESIGN OF NETWORK SYSTEM FOR PETROCHEMICAL PLANT AND THE IMPLEMENTATION

在对石油化工工厂网络组成和特点等进行分析的基础上,提出了过程控制网与管理信息网一体化设计的理念,并从路由链路设计、过程控制网与管理信息网的安全连接、管理信息网内部的安全域划分等方面进行详细阐述,对工业以及网、OPC、网络安全等实现一体化设计的关键技术进行了分析,从而为实现石油化工厂"管理一体化"提供了一体化的网络平台。

Based on the analysis of network composition of petrochemical plant,this article advances the idea of integrated design of process control network and management information network,introduces in detail the network linkage design,the security linkage between process control network and management information network and the partition of security domains in management information network,and also analyzes key technologies for the integrated design.
