Title
(EN) WIRELESS DETONATOR ASSEMBLY
(FR) ENSEMBLE DÉTONATEUR SANS FIL
Abstract
(EN) A wireless detonator assembly which includes a detonator, a receiver, a printed circuit board with a stored key which is hardwired onto the board during manufacture of the detonator assembly and control logic which allows the detonator to be fired only if the control logic extracts from a signal, received by the receiver, a reference key which is identical to the stored key.
(FR) L'invention concerne un ensemble détonateur sans fil qui comprend un détonateur, un récepteur, une carte de circuit imprimé avec une clé mémorisée qui est câblée sur la carte pendant la fabrication de l'ensemble détonateur et une logique de commande qui permet que le détonateur soit déclenché uniquement si la logique de commande extrait à partir d'un signal, reçu par le récepteur, une clé de référence qui est identique à la clé mémorisée.
