摘　　要：无线射频识别(radio frequency identification,RFID)技术是实现制造业智能化和制造资源互联的重要信息感知技术,然而柔性制造环境下RFID数据漏读问题严重影响了信息感知质量。通过从单阅读器内部分数据漏读和阅读器层级的整体数据漏读两个方面对RFID数据漏读问题进行分析,构建RFID数据漏读问题模型;考虑工件加工工艺路线和物料搬运路径信息约束,提出基于加工路径约束和固定滑动窗口算法集成(machining path constraint and fixed sliding window algorithm,MPC-FSWA)的漏读数据补全方法。实验研究表明,MPC-FSWA方法能对柔性制造环境下的RFID数据漏读进行有效补全。Radio frequency identification(RFID)is an important information sensing technology to realize the intelligent manufacturing industry and the interconnection of manufacturing resources.However,the RFID data missing problem in the flexible manufacturing environment seriously affects the quality of information sensing.To analyze the RFID data missing problem from the aspects of partial data missing in single RFID level and whole data miss in the multi-RFID environment,a RFID data missing model was built.A machining path constraint and fixed sliding window algorithm integrated(MPC-FSWA)missing date completion approach was proposed,where the constraints of work-piece processing routes and material handling paths were considered.Experimental studies show that the MPC-FSWA approach can effectively complete the RFID missing data in the flexible manufacturing environment.
