DEVICE FOR DETECTING THE DIRECTION OF PASSING AN OBJECT TO A DETERMINED FRONTIER ZONE

摘要

The invention relates to a system for detecting the direction of passage of an object comprising an electronic identification means, to a border zone of passage between two distinct spaces. The detection system comprises: a first read-interrogation element ( 16) having a first antenna (16a) having a first detection lobe (16b), the first read-interrogation element monitoring a first region (20a) located on one side of said crossing border zone, - a second read-interrogation (18) comprising a second antenna (18a) having a second detection lobe (18b) not covering the first detection lobe, the second reading-interrogating element monitoring a second region (20b) located on the other side of this crossing border zone, and- processing means (22) connected to the first and second read-interrogation elements, the processing means determining the direction of passage of the object in question. according to the order of crossing of these two regions.
