目前，OPC 技術在過程控制系統中獲得了廣泛的應用，但OPC 技術以Microsoft 公司的OLE／COM技術為基礎，應用基本上仍然局限在Windows 系統平臺，而目前企業級的上層應用系統大多采用的是J2EE體系結構，如何在J2EE 體系結構下應用OPC 技術這將是本文要討論的問題。本文探討了Java 與OPC 相結合的技術，并構建了一種基于OPC 和Java 技術的分布式遠程監控系統。這種系統具有良好的開放性、可擴展性和平臺無關性特點。

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.
