摘　　要：针对RFID数据读取不确定性造成的数据冗余和脏数据现象,文章通过标签不同时刻的信号强度估算标签移动的速度和过程时间,利用估算的结果清除冗余数据和脏数据,同时将数据处理和数据输出过程并行执行。该方法大大提升了冗余数据和脏数据清理效果,缩短了算法的执行时间,提高数据的准确性和有效性。仿真实验表明,文中提出的方法与传统RFID数据清洗算法相比,数据清洗效果优势显著,所需处理时间和空间大幅降低。证明了该算法的可行性。In order to handle redundant data and ＂dirty＂ data caused by uncertainty of RFID data reading , this paper proposed a new method ,which estimated the speed of RFID tags movement and process time according to the signal strength of RFID tags at different times and then cleaned redundant data and dirty data based on the results of the estimation. The method ran processing and output of data in parallel. This method greatly enhances the cleaning effect of redundant data and dirty data and shortens the execution time. It also improves accuracy and validity of data. The results of simulation experiments showed that the proposed method, compared with traditional RFID data cleaning algorithm, has the advantages at the effect of data cleaning and greatly reduced time and space of processing. The method is proved to be feasible.
