| 摘要 |
<p>The invention concerns systems for identifying with electronic labels objects of various shapes comprising metal parts likely to disturb the propagation of the interrogating electromagnetic waves of the labels (102). It consists in providing a scanner (107) with a set of antennae (104) whereof the localisation and/or characteristics are different. Said antennae are connected to the scanner by a multiplexer (106). The latter successively activates each of the antennae by means of a brief interrogating signal. When the label (102) reacts to the interrogation of one of said antennae, the whole scanning process of said label by said antenna is launched. It enables to identify casks (101) moving past on a conveyor (103).</p> |
