【摘要】：近几年,国家制造业信息化、敏捷化工程的大力推进,在离散型装备制造业中,以ERP为代表的上层生产管理信息系统和以SFC为代表的底层车间控制自动化系统一定程度上为企业创造了效益。但是上层PMI类系统与底层SFC类系统间的断层,造成企业对制造过程管理监控不足,严重制约了精益化管理的推进。MES的提出很好弥补了PMI与SFC之间的断层,实现了系统间实时制造信息的交互共享,增强了企业对质量、成本、资源等的控制能力,推动了企业CIMS战略的发展。市场主体向买方的转变,对企业应对市场变化和柔性制造的能力提出了更高的要求,现有MES的生产信息采集方式在信息的实时性、准确性等方面都存在不足。近几年,RFID技术的不断成熟,其在自动对象标识、数据存储等方面的优越性,为满足MES中生产信息采集系统的实时性、精确性要求提供了强有力的技术支撑,因此将RFID技术与MES系统原理相结合的研究分析具有一定的理论实用价值。本文在研究MES基本原理、体系结构、数据集成方式、生产信息采集系统架构、计划调度算法的基础上,分析了装备制造业生产制造特点、MES功能优势及不足,并针对现状提出了基于RFID的装备制造业MES的研究方案,利用Multi-Agent技术和CORBA理论设计了方案的功能结构模型,给出了实现的技术方法；重点研究基于RFID的生产信息采集系统,提出解决RFID技术与MES结合关键问题的技术方法和车间RFID网络规划模型,并提出基于Metropolis规则的改进遗传算法来解决RFID网络规划中覆盖率及读写器冲突的问题,实例验证中取得了满意效果；最后,给出了本文提出方案在S公司的具体实现,并分析研究方案的实际应用效果。实践证明本文提出的基于RFID的装备制造业MES应用方案的可行性及研究成果的实用性,为进一步的研究和应用提供了依据和方向。
[Abstract]:In recent years, the national manufacturing industry informatization, agile project vigorously promote, in discrete equipment manufacturing industry, represented by ERP, the production management information system and automatic control system with the bottom of the workshop represented by SFC to a certain extent for enterprises to create benefits. But the upper class PMI system and the SFC system the fault caused by deficiency of enterprise of manufacturing process management, seriously restrict the lean management to promote.MES offers very good make up between PMI and SFC faults, realizes the interactive real-time manufacturing information system sharing between enterprises to enhance the quality, cost, ability to control resources, promote the development of the CIMS strategy of enterprises.
The main body of the market to the buyer's change, put forward higher requirements on the ability of enterprises to cope with the market changes and flexible manufacturing, the existing MES production way of collecting information in real-time information, accuracy and other aspects are insufficient. In recent years, the development of RFID technology, the automatic object identification, the superiority of the data storage, to meet the real-time production information acquisition system in MES, provides a strong technical support accuracy requirements, so will study the principle of RFID technology combined with MES system analysis theory has certain practical value.
In this paper, the basic principle, the system structure of MES, data integration, production information acquisition system architecture based scheduling algorithm, analysis of the equipment manufacturing industry production characteristics, advantages and disadvantages of MES function, and according to the present situation this paper puts forward a scheme of RFID system equipment manufacturing industry based on MES, designed the function structure model the scheme of using Multi-Agent technology and CORBA theory, gives the implementation method; focus on the production of RFID data collection system, we propose a method to solve the car and RFID technology combined with MES key issues of RFID network planning model, and proposes an improved genetic algorithm based on Metropolis rule to solve the coverage rate and the reader collision the problem of RFID network planning, example verification achieved satisfactory results; finally, this paper presents the implementation scheme in S company, and analysis research The actual application effect of the case.
Practice has proved that the feasibility and research results of MES application plan based on RFID in equipment manufacturing industry proposed in this paper provide a basis and direction for further research and application.
