【摘要】 柔性制造系统是具有柔性且自动化程度高的制造系统。FMS的复杂性决定了其控制系统的研究开发是一项技术复杂、周期长、成本高的活动。为能及时快速满足市场需要,开发出具有可配置性、可重构性的FMS控制系统具有较大的实际应用意义。本文分析了FMS集中式、递阶式、分布式、混合式控制系统体系结构特点。以一般的FMS为背景,采用递阶分布式作为控制系统的体系结构,同时对FMS递阶分布式控制系统的组成、体系结构特点进行了论述。基于对FMS控制系统建立的功能模型与面向对象模型,对控制系统中的各功能组件进行了设计,建立了基于CORBA组件技术的控制系统软件结构模型。将开发的控制系统模型在北京交通大学的教学型柔性制造系统中得以应用,并论述了嵌入式系统的开发和移植以及CORBA技术如何在嵌入式操作系统上得以实现的基本过程。最后,分析了模型的应用效果和所开发的控制系统的特点,并总结了全文工作的主要内容,讨论了一些不足和今后应该进一步开展的工作。图30幅,表1个,参考文献48篇。更多还原

【Abstract】 FMS (Flexible Manufacturing System) is a manufacturing system with flexible character and high degree of automation. As a result of its complexity, developing control system for FMS needs much time, money and technology. It will make great significance to develop control system with the characteristics of configurability and reconfigureability to satisfy the market requires rapidly.After analyzing the characteristics of centralized, hierarchical, distributed, hybrid-architecture, hierarchical distributed control system architecture of FMS is built under the background of general FMS, the components and characteristics of this architecture is discussed. Based on the functional model and object-oriented model of FMS, the functional components of control system are designed, and the software architecture model of the control system is proposed with the CORBA component technology. The software architecture model has been applied to a didactical FMS in Beijing Jiao Tong University, and the process is described that embedded system is transplanted to an ARM embedded development platform and CORBA is realized on an embedded operating system. Finally, application effects of model and the characteristics of developed control system are described, and the research work of the whole dissertation is concluded, the problem and further work is discussed.更多还原
