基于OPC XML-DA的工程支持和服务

Research of the Engineering Support and Service System Based on OPC XML-DA

针对企业底层设备复杂控制和企业应用层管理的需要,结合最新的Web Services技术,通过对OPC XML-DA技术的应用,借助Internet实现远程的工程支持和服务.这是一种全新的框架和实现方式,区别于传统通过COM/DCOM技术来实现的异地通信和控制,能实现真正意义上的跨操作系统的远程工程支持和服务,满足复杂异构设备的远程控制和服务要求.

OPC XML - DA defines a standard method for accessing automation data in the industry field. This protocol relies on Web Service communications allowing a great compatibility and a software/hardware independent definition. In this paper,I propose to develop a system that grounds on the protocol of OPC XML,which supply remote project supports and services for industry clients. It＇s different from the traditional applications that ground on COM/DCOM. It can in deed carry out the applications among different equipments and devices, and can be adopted in different operate system, for example UNIX.
