【摘要】 传统的工业控制软件采用原有的专用驱动模式，工业软件开发商需要开发大量相应的驱动程序来连接各种控制设备。由于不同客户有着不同的需要，同时也存在着不同的数据传输协议，因此也一直没有完整的解决方案。问题的关键在于系统之间的接口没有统一标准，OPC作为一个工业标准应运而生。新兴的、基于微软COM／DCOM技术的OPC“软总线”技术，为工业控制软件的数据通讯(数据采集)、异构系统的集成和多层软件体系架构提供新的标准。可以实现自动化控制软件和硬件的万能连接，从而实现数据的灵活配置和多种系统的真正集成。本文简单阐述了COM／DCOM技术，说明OPC技术实现的基础；全面的介绍OPC的基本概念、OPC的客户／服务器体系结构。本文通过深入研究OPC在异构系统集成中的应用，以宇电智能仪表AJ808为研究对象，探索出OPC数据访问服务器的设计方法，并通过了兼容性测试，实现了驱动程序的标准化，最后通过实例阐述了OPC服务器在组态软件中的实际应用。更多还原

【Abstract】 The traditional industrial control software adopts the already existing customization driver mode, software vendor has to develop a great deal corresponding driver for various kinds of hardwares. Owing to the different requires of clients and the different transport protocols, there are not still whole deal with. The key is that there are not uniform interface between systems.The new developing one, OPC "softbus" technology on the basis of Microsoft COM/DCOM, for the data communication of the industrial control (Data Collection), the integration of the heterogeneous system and the construction of the mufti-layer software system, offer the new standard. OPC can achieve "omnipotent connection" between automatic control software and hardware, and consequently, realize flexible configuration and genuine integration in systems.This thesis, is it to COM/DCOM simple exposition of technology, prove OPC foundation of technology to pass. And it overall illuminates the basic OPC conception, the structure of the C/S. This paper lucubrates the application of OPC in the heterogeneous system integration, and search out the design method of OPC date access server based on yudian intelligent instrument AI808. This server already passes compatibility test and realize the standardization of driver. Finally, this thesis gives a practical application of OPC server in configuration software.更多还原
