Abstract

The present invention discloses an RFID data cleaning method and apparatus. The method includes the following steps that: a distance from an RFID tag to a reader is determined; if the distance from the RFID tag to the reader is greater than the reading range radius of the reader, it is determined that RFID data carried by the RFID tag are cleaned; and if the distance from the RFID tag to the reader is not greater than the reading range radius of the reader, whether the RFID data are cleaned is determined according to the current reading rate of the reader. According to the RFID data cleaning method and apparatus provided by the technical schemes of the invention, the effective cleaning of the RFID data can be realized, and cleaning efficiency and precision can be improved.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to an RFID data cleaning method and device. Background technique [0002] RFID (Radio Frequency Identification) technology is an automatic identification and data acquisition technology. The basic working principle of RFID is that the reader first sends energy to the RFID tag, the RFID tag returns RFID data to the reader, the reader decodes the RFID data and returns the decoded data to the host. [0003] Compared with ordinary data, RFID data has the following characteristics: [0004] (1) Temporality, dynamics and relevance. Observation data about state changes of tag objects is dynamically generated on site, and these observation data include data such as observation time, object position and object state corresponding to that time. An RFID data does not exist independently, but is interrelated, and relevance is derived from temporality and dynamics. Temporal associati...
