基于RFID技术的制造过程链节点信息监控研究

针对目前缺少能够自动、实时、准确地获取离散制造过程中发生的各种信息的监控平台,提出了基于RFID技术的制造过程链节点信息监控研究.首先构造制造过程链节点信息模型,模型中包括制造过程及状态信息.其次分析模型中参数的获取途径和方法,给出模型中参数与输入变量的计算方法,实现数据采集系统的数据到监控平台的模型信息的映射,最后构建信息采集工具和监控平台.通过在某产品制造过程中应用,表明通过节点信息监控不但改变物流与信息流不同步、不同时,使制造过程中各环节的生产计划与制造执行相一致.

Research on monitoring system of workshop manufacturing process based on RFID

In order to catch production logistics information automatically,real time and exactly,the viewpoint based on data acquisition monitoring model of work in process（WIP） status was put forward.The concept of monitoring model of lean production logistics operation is put forward,with the model based on the real time data acquisition combining the characteristics of tracking and managing WIP in production workshop.The WIP status monitoring model and computing expressions are given in this paper on the basis of status identification and tracking to WIP.It is pointed out that the intelligent data acquisition and sensor network technologies are key points of realizing lean production logistics.Finally,the lean production logistics operation monitoring model is presented by analyzing the structure of the production logistics monitoring system.The development of the monitoring applying system proves the model is practicable and algorithmic expressions are correct.
