基于WebService和OPC技术的综合监控系统

Integrated Monitoring System Using WebService and OPC Technology

基于COM/DCOM技术的OPC技术在工业控制和监控系统得到了广泛的应用,但是COM/DCOM的一些技术缺陷还是限制OPC技术进一步的推广应用。本文分析了这些不足,并提出了使用WebService扩展OPC技术的方法,并将这项技术应用到了综合监控系统中。由于本文的方法可以消除平台差异,而且在与其它其系统集成方面更加简单,所以更具实用性。

Based on COM/DCOM technique,OPC protocal is used widely.But there is some drawbacks that prevent it from being even widely used.We analsyze the problem,and propose an integrated monitoring framework using the WebService extending theOPC.The platform difference and information bottleneck is cleared in our method.It s more powerfull and usefull.
