基于OPC 和Java 的远程监控系统架构研究与设计

目前，OPC 技术在过程控制系统中获得了广泛的应用，但OPC 技术以Microsoft 公司的OLE／COM技术为基础，应用基本上仍然局限在Windows 系统平台，而目前企业级的上层应用系统大多采用的是J2EE体系结构，如何在J2EE 体系结构下应用OPC 技术这将是本文要讨论的问题。本文探讨了Java 与OPC 相结合的技术，并构建了一种基于OPC 和Java 技术的分布式远程监控系统。这种系统具有良好的开放性、可扩展性和平台无关性特点。

Research and Design of Distributed Monitoring System Based on OPC and Java Technology
JIAO Qingsong, WU Yingliang （School of Electrical Business, South China University of Technology，Guangzhou 510006，China） Abstract：At present,OPC Technology was applied widely in Process Control system. OPC was based on OLE/COM technology of Microsoft and was confined to Windows.But the application layer mostly adopted the architecture of J2EE in enterprises at present. In this paper the interconnect technology
between Java and OPC was discussed，as well as a new architecture of distributed remote monitoring system was presented.This system had the characteristic of open, extensibility and platform independence.
