【摘要】：在“工业4.0”的大背景下,模具加工自动化是未来模具技术发展的主要趋势,模具车间物流自动化作为模具加工自动化的组成内容,是今后模具行业发展的一个重要方面。模具车间现场物流过程信息的实时采集则是实现物流自动化的关键。本文结合模具车间物流特点,将RFID(Radio Frequency IDentification)技术引入到模具生产物流过程,重点围绕物流信息的自动采集和处理,深入研究了基于RFID的模具车间物流系统的实现及其涉及到的关键技术。首先,通过充分分析模具车间物流过程,确定物流信息特征及处理需求,结合物联网技术,构建了基于RFID的模具企业物流管理系统架构。在此基础上提出了基于RFID的物流运输过程事件处理机制,通过对物流过程中海量标签事件进行有效的过滤、封装,以及对关键性业务事件的处理、融合使其最终转化为模具企业最为关心的监控事件。基于上述的事件信息处理,实现了物流过程中各种信息的有效转化与快速传输。然后,针对模具车间物流任务生成特点,提出了物流小车调度机制,通过任务分配策略将物流任务及时的分配给物流小车,并在拥塞避免的前提下完成小车物流路线的规划工作,在物流任务执行过程中实时检测拥塞冲突,发生冲突时及时的采取拥塞避免策略。最后,在上述研究的基础上,采用C/S和B/S相结合的混合开发模式,开发了基于RFID的模具车间物流系统,实现了对加工现场物流信息的实时采集、对物流资源的实时调度和对物流过程的实时监控,为模具加工自动化的全面推进奠定了良好的基础。
[Abstract]:Under the background of "Industry 4.0", the automation of mould processing is the main trend of the development of mould technology in the future. As a component part of the automation of mould processing, the automation of mould shop logistics is an important aspect of the development of mould industry in the future. The real-time collection of material flow information in mould workshop is the key to realize logistics automation. Based on the characteristics of mould shop logistics, this paper introduces RFID(Radio Frequency identity technology into the process of mould production logistics, focusing on the automatic collection and processing of logistics information. The realization of mould workshop logistics system based on RFID and its key technology are studied. Firstly, the logistics management system architecture of mould enterprise based on RFID is constructed by fully analyzing the process of mould shop logistics, determining the characteristics of logistics information and processing requirements, and combining with the technology of Internet of things. On this basis, this paper puts forward the event handling mechanism of logistics transportation process based on RFID, which can effectively filter, encapsulate and deal with the key business events through the effective filtering and encapsulation of mass label events in the logistics process. The fusion turns it into the monitoring event that the mould enterprise is most concerned about. Based on the above-mentioned event information processing, all kinds of information in the process of logistics are effectively transformed and quickly transmitted. Then, according to the characteristics of logistics task generation in mould workshop, the scheduling mechanism of logistics vehicle is put forward, and the logistics task is assigned to logistics cart timely through task allocation strategy. Under the premise of avoiding congestion, the planning of vehicle logistics route is completed, the congestion conflict is detected in real time during the process of logistics task execution, and the congestion avoidance strategy is adopted in time when the conflict occurs. Finally, on the basis of the above research, a mould workshop logistics system based on RFID is developed by using the mixed development mode of C / S and B / S, which realizes the real-time collection of the material flow information on the processing site. The real-time scheduling of logistics resources and the real-time monitoring of logistics process lay a good foundation for the overall promotion of die processing automation.
