A Fiber-Optic-Based Protocol for Manufacturing System Networking

计算机通信网络对于大规模制造企业中管理、工程设计和生产过程的集成变得越来越重要。采用光纤作为传输介质可以显著提高计算机集成制造（CIM）网络的效率和灵活性。由于光纤的物理特性与同轴电缆的物理特性有很大的不同，因此需要对现有CIM组网架构中的拓扑结构和介质接入机制进行修改。本研究的目的是进行办公室与工厂综合通讯网路的基础与应用研究。该研究将侧重于高速光纤网络协议的开发和分析，该协议将集成实时分布式制造过程与工程设计和工厂管理数据库。(1)制造自动化协议，(2)技术和办公协议，(3)综合业务数字网等国家重点项目将直接受益于本研究。

Computer communication networks are becoming increasingly important for integration of administrative, engineering design, and production processes in the large-scale manufacturing business. The efficiency and flexibility of networks for computer-integrated manufacturing (CIM) can be significantly improved by using optical fibers as the transmission media. Since the physical characteristics of optical fibers are significantly different from those of coaxial cables, the topology and medium access mechanisms in the existing CIM networking architectures need to be revised. The objective of this research is to conduct basic and applied research in integrated office and factory communication networks. The research will focus on the development and analysis of a high- speed fiber-optic-based network protocol that will integrate real- time distributed manufacturing processes with engineering design and plant management databases. Projects of national importance like (1) Manufacturing Automation Protocol, (2) Technical and Office Protocols, and (3) Integrated Services Digital Network will directly benefit from this research.
