| 摘要: |
| 为了实现从大量不可靠、冗余的RFID（radio frequency identification）流数据中提取有效信息，提高RFID系统中数据的质量，提出了一种基于有限状态机的RFID 流数据过滤与清理方法.实验结果表明：该方法能够有效过滤系统外标签数据，清理系统内部冗余标签数据，筛选有效标签数据，并能够降低漏读、误读带来的风险.最后，利用地理信息系统的可视化技术，将过滤与清理结果展示在地图上. |

| Abstract: |
| In order to extract useful information from a large number of redundant and unreliable RFID (radio frequency identification) streaming data and improve the data quality of the RFID system, a filtering and cleaning method based on finite state machine for RFID streaming data is proposed. According to the experiment, suppressing interference tag data, filtering redundant tag data and extracting effective tag data can be realized in this method with reduced risk of system omission and false positives. Finally, using GIS technologies the monitoring and tracking results are displayed on the world map. |
