摘要
OPC(开放性、生产力和协作);(以前的“OLE for Process Control”)标准今天已被接受为设计和开发制造和过程自动化工业应用的工业标准。然而,由于其复杂性和难度,OPC标准在高校的实际工业应用的发展受到限制。本文不仅介绍了OPC标准的现状,还讨论了OPC标准存在的问题以及如何管理和克服这些问题。然后提出了基于新的OPC统一架构(UA)规范的通用集成体系结构,并给出了仿真的初步结果。介绍了该体系结构的潜在应用领域以及提高系统效率和可靠性的冗余策略。
Research and development of OPC client-server architectures for manufacturing and process automation
The OPC (Openness, Productivity, and Collaboration; formerly "OLE for Process Control") standards today have been accepted as industrial standards for designing and developing industrial applications in manufacturing and process automation. However, the development of real industrial applications using the OPC standards at universities is limited due to the complexity and difficulty. In this paper, not only the current state of the OPC standards is provided, but also the current problems and how they can be managed and overcome are discussed. The general integration architecture based on the new OPC Unified Architecture (UA) specifications is then proposed and presented together with the initial results from the performed simulation. The potential areas of the proposed architecture and the redundancy strategies to increase the efficiency and reliability of the system are also introduced.
