【摘要】：随着科学技术的发展和生活水平的提高,传统的大批量生产方式已不能满足企业的要求,人们对产品的需求向着多样化、新颖化的方向发展。为了满足多品种、小批量的生产方式的需要,一门新的现代制造技术——柔性制造系统(FMS)应运而生,并得到迅速的发展。柔性制造系统将微电子学、计算机和系统工程等技术有机地结合起来,有效并较好的解决了机械制造高自动化与柔性的矛盾。柔性制造技术已成为各工业化国家机械制造自动化的研制发展重点,对制造业的发展和进步发挥了重要作用。本文结合具体的工程实践,介绍了从FMS的设计、安装、调试,到最后系统试运行的整个研发过程。在FMS的设计阶段,根据加工工艺和加工对象的具体要求,对系统进行结构和布局设计。根据FMS控制系统的特点,选用Petri网模型对系统进行建模。研究了Petri网的基本概念和特点,对FMS的各个子系统进行建模,并对模型进行性能分析,验证模型的可行性。在FMS物流系统方面,提出利用RFID技术解决FMS中工件监控和管理问题。而系统的实时通信方面采用Profibus现场总线,运用Profibus现场总线,构建三层递阶式通信结构,解决管理层与单元层、单元层与设备层之间的通信；最后通过系统运行实例,验证系统功能的有效性。
[Abstract]:With the development of science and technology and the improvement of living standards, the traditional mass production mode can not meet the requirements of enterprises, people's demand for products towards the direction of diversification and novelty, in order to meet the needs of a variety of varieties. FMS (flexible Manufacturing system), a new modern manufacturing technology, has been developed rapidly. FMS will be microelectronics. Technologies such as computer and systems engineering are organically integrated. It has effectively solved the contradiction between high automation and flexibility in mechanical manufacturing. Flexible manufacturing technology has become the focus of the research and development of mechanical manufacturing automation in various industrialized countries. It plays an important role in the development and progress of manufacturing industry. This paper introduces the whole research and development process from the design, installation, debugging of FMS to the final system trial run. It is in the design stage of FMS. The structure and layout of the system are designed according to the specific requirements of the processing process and the machining objects. The characteristics of the FMS control system are also discussed. Petri net model is used to model the system. The basic concept and characteristics of Petri net are studied. Each subsystem of FMS is modeled and the performance of the model is analyzed. Verify the feasibility of the model. In the FMS logistics system. This paper proposes to use RFID technology to solve the problem of monitoring and management of workpiece in FMS, while Profibus fieldbus and Profibus fieldbus are used in the real-time communication of the system. A three-level hierarchical communication structure is constructed to resolve the communication between the management and the unit layer and between the unit layer and the device layer. Finally, the effectiveness of the system function is verified by a system running example.
