| 摘要 |
The invention concerns a control and/or monitoring device comprising pairs (P,P') of interactive members ( 1, 2; 1', 2' ) each of which includes an electronic label ( 1, 1' ) identified by a specific identification code (KID 1, KID 1' ) and a reader ( 2, 2' ) communicating with said label ( 1, 1' ). For each pair (P) of interactive members, the inventive device also comprises a state encoder at least partially borne by the label ( 1 ), said encoder producing a state signal which is accessible to the reader ( 2 ) and representing a logic or analog state affecting the label ( 1 ) or a relationship between the label ( 1 ) and the reader ( 2 ).
