METHOD OF DISCRIMINATING RFID TAGS IN MOTION FROM STATIC RFID TAGS

摘要

The invention relates to a method for discriminating tags in motion from static tags. It comprises the following steps:- sending (E1), from first and second remote reading stations (A, B) placed along the path of the tags in motion, first and second interrogation signals destined for the RFID tags, - determining (E2,E3,E4) whether the two reading stations receive response signals from tags in response respectively to said first and second radiofrequency interrogation signals so that, for a current tag, if just one of the two reading stations receives a response signal from said current tag, said current tag is a static tag, and if both reading stations each receive a response signal from said current tag, a method of learning based recognition is applied to determine whether the current tag is static or in motion.
