SYSTEM FOR IDENTIFYING MULTIPLE RFID TAGS BASED ON DIFFERENT HAMMING DISTANCES AND ASSIGNMENT OF POINTS, FOR ENVIRONMENTS OF HIGH ELECTROMAGNETIC INTERFERENCE.

摘要

System for identifying multiple RFID tags based on different hamming distances and assignment of points, for environments of high electromagnetic interference, which provides a method for increasing the rate of effectiveness at the moment of identifying the RFID tags with a reduced number of readings. The system needs the number of tags to be identified and uses a database with the information (codes) of the objects to be identified, a RFID reader, which emits a signal to the tags, an antenna for receiving and emitting a signal between the reader and the tags. The fact of performing a reduced number of readings allows the system to obtain free processing time to be applied to other computational instances. In addition, the method increases the reliability during the identification of the RFID tag codes, generating therefore a safety environment for the decision making. The method may be used along with other identification protocols for achieving a higher effectiveness at the moment o f identifying tags.
