| 摘要: |
| 扼要分析了中间件原理,对Windows平台下通信技术的核心思想进行了集中解剖,得出两者共同的核心价值都在于分离。通过对Windows平台下通信技术的研究,指出了过程控制对象链接嵌入式技术OPC(OLEforProcessControl)的不足,并根据当前工控系统互联的现状,从中间件角度对工控系统互联的核心技术进行了探讨,对工控系统互联技术的发展方向提出了合理见解,认为开发真正开放的工控系统中间件规范是实现分布式工控系统的有效途径。 |

| Abstract: |
| Principle of middleware is analyzed in brief,and the kernel idea of communication technology on Windows platform is studied together.Their common kernel value rests with separation.Based on the research of communication technology on Windows platform,insufficiencies of OPC(OLE for Process Control)are concluded.According to the status quo of interconnection of industrial control systems,its kernel technology is discussed from the view of middleware.The author provides views for its development trend and regards the establishment of real open middleware standard as an effective way for the realization of distributed industrial control system. |
