目前，OPC 技術(shù)在過程控制系統(tǒng)中獲得了廣泛的應用，但OPC 技術(shù)以Microsoft 公司的OLE／COM技術(shù)為基礎(chǔ)，應用基本上仍然局限在Windows 系統(tǒng)平臺，而目前企業(yè)級的上層應用系統(tǒng)大多采用的是J2EE體系結(jié)構(gòu)，如何在J2EE 體系結(jié)構(gòu)下應用OPC 技術(shù)這將是本文要討論的問題。本文探討了Java 與OPC 相結(jié)合的技術(shù)，并構(gòu)建了一種基于OPC 和Java 技術(shù)的分布式遠程監(jiān)控系統(tǒng)。這種系統(tǒng)具有良好的開放性、可擴展性和平臺無關(guān)性特點。

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.
