Abstract (en)
[origin: CA3122858A1] A method for igniting an assembly of electronic detonators (1) comprises: - receipt, by a receiving device (30) associated with one or more electronic detonators (1), of an ignition command from a transmitted sequence of ignition commands (100) comprising at least two ignition commands, a synchronisation delay (t2, t4) being associated with each ignition command; - counting down, from the time of receipt of the ignition command, the synchronisation delay (t2, t4) associated with the received ignition command; - counting down an ignition delay (tdelay) associated with each electronic detonator (1) from a synchronisation time (Is) corresponding to the time at which the countdown of the synchronisation delay (t2, t4) is complete; and - igniting each electronic detonator (1) once the countdown of the ignition delay (t delay) is complete.
