Abstract: A wireless electronic detonator includes a primary source of energy and at least one functional module. A power switch is disposed between the primary source of energy and the functional module to connect or disconnect the functional module and the primary source of energy. A controller controls the power switch and includes an optical receiver to detect and demodulate a light signal emitted by a control console, The controller generates a control signal according to the demodulated light signal to at least control the power switch. A wireless detonation system includes the wireless electronic detonator and the control console configured to emit a light signal, and method for activating the wireless electronic detonator.

Abstract: A wireless electronic detonator includes an energy source and functional modules. A first switching switch is provided between the energy source and the functional modules, making it possible to connect or not connect the energy source to the functional modules. A control module for controlling the first switching means includes a module for recovering radio energy configured to receive a radio signal from a control console, to recover the electric energy in the radio signal received, to generate an energy recovery signal (VRF) representative of the level of electric energy recovered, and to generate as output a control signal (VOUT) as a function of the recovered energy, the control signal controlling the first switch.

Abstract: A firing method for a set of electronic detonators includes receipt, by a receiving device associated with one or more electronic detonators, of an ignition command from a transmitted sequence of ignition commands including at least two ignition commands, a synchronisation delay being associated with each ignition command. A counting down, from the time of receipt of the ignition command, of the synchronisation delay associated with the received ignition command, and a counting down of an ignition delay associated with each electronic detonator from a synchronisation time corresponding to the time at which the countdown of the synchronisation delay is complete, are carried out. Each electronic detonator is ignited once the countdown of the ignition delay is complete. An electronic detonator includes a reception device, first and second countdown devices and a firing device.
